Description

Influenza virus and oil in water emulsion adjuvant are induced the purposes in the immunogenic composition that the B-memory cell of CD-4 T cell and/or improvement replys in preparation
Technical field
The present invention relates to influenza vaccine formulation and the vaccination regimen that is used for immunity antagonism influenza disease.Specifically; The present invention relates to contain bacterin preparation, its purposes in medicine of oil in water emulsion adjuvant and the 3D-MPL that chooses wantonly; Especially it is increasing the purposes aspect the immunne response of influenza antigens; And relate to method for preparing, but wherein said O/w emulsion comprises sterol metabolism oil and emulsifying agent.
Technical background
Influenza virus is one of the most ubiquitous virus in the world, both can infect the mankind, also can infect domestic animal.Influenza produces great financial burden, sickness rate and even mortality rate.
Influenza virus is the RNA enveloped virus, and particulate diameter is about 125nm.Basic composition is of influenza virus: inner is and the bonded ribonucleic acid of nucleoprotein (RNA) nucleocapsid or core that external packets is around the viral tunicle of double-layer of lipoid structure and outer glycoprotein.Virus mainly is made up of stromatin by film inner layer, and skin mainly is the lipid material that the host originates.Influenza virus comprises two kinds of surface antigens: glycoprotein neuraminidase (NA) and hemagglutinin (HA), they are emerging on the particle surface with the long furcella of 10-12nm.Be exactly these surface proteins, especially hemagglutinin, determined the antigenic specificity of influenza subtype.
These surface antigens experience the change that some causes the variation of influenza antigen property progressively, sometimes apace.These antigenic changes are called ' drift ' and ' conversion '; Be unpredictalbe, see to have remarkable influence, because they finally cause occurring new influenza strain by the immunology viewpoint; Can make the viral escape immune system, almost all cause well-known epidemic diseases every year.
The strains of influenza viruses that joins each season in the influenza vaccines is confirmed by collaborative national health management board of WHO and production of vaccine merchant jointly.
HA is a most important antigen of confirming the serological specificity of different influenza strains.The albumen of this 75-80kD comprises numerous antigenic determinants, wherein several being located in the zone that the experience sequence changes in the different strains (strain specific determinant), and remaining is arranged in the total zone of many HA molecules (common determinant).
Influenza virus all causes almost annual winter is very popular, the infection rate of first (A) type or second (B) type virus in the time period in 6 weeks up to 40%.Influenza infection produces various diseases, by subclinical infection to slight upper respiratory tract infection to serious viral pneumonia.Typical flu outbreak causes that the sickness rate of pneumonia and lower respiratory illness increases, and evidence is that admission rate or mortality rate increase.Severity of disease is mainly determined by host's age, its immune state and infection site.
65 years old with above old people especially vulnerable, account for the 80-90% of all influenza associated deaths of developed country.The individuality of suffering from basic chronic disease also very might experience this complication.The child also possibly suffer from serious disease.Therefore, these colonies especially need protected.Except these ' risks ' the colony, the health adult's inoculation to contacting with the old people is also recommended by health authority.
Inoculation plays a crucial role to controlling annual flu outbreak.Present available influenza vaccines are inactivation influenza vaccines or attenuated live influenza vaccines.The inactivation influenza vaccines by 3 kinds maybe forms the antigen preparation thing forms: the inactivation totivirus, wherein the virion of purification by detergent or other reagent destruction with the subvirus body (so-called " split vaccine ") of lipin dissolving peplos or the HA or the NA (subunit vaccine) of purification.These inactivated vaccines intramusculars (i.m.) or intranasal (i.n.) give.
The influenza vaccines of all kinds all are trivalent vaccine usually.In general, their antigen of containing derives from two kinds of influenza A virus strains and a kind of Influenza B virus strain.According to single radiation immunity diffusion (SRD) (J.M.Wood etc.: An improved single radialimmunodiffusion technique for the assay of influenza haemaggiutininantigen:adaptation for potency determination of inactivated whole virusand subunit vaccines.J.Biol.Stand.5 (1977) 237-247; J.M.Wood etc.; International collaborative study of single radial diffusion and Immunoelectrophoresis techniques for the assay of haemaggiutininantigen of influenza virus.J.Biol.Stand.9 (1981) 317-330) detection; In most of the cases, standard 0.5 ml ID contains 15 μ g hemagglutinin antigen components of every kind of strain.
Present available influenza vaccines be considered to all age group all be safe (De Donato etc., 1999, Vaccine, 17,3094-3101).But, evidence suggests that seldom current influenza vaccines have effect in the child below 2 years old.And prevention has typically confirmed that the report ratio of the vaccine potency of influenza disease is 23-72% to old people, and this significantly is lower than effective percentage (Govaert, 1994, J.Am.Med.Assoc, 21, the 166-1665 of the 60-90% that younger adult is reported; Gross, 1995, Ann Intern.Med.123,523-527).Showed already; The effectiveness of influenza vaccines is relevant with the serum titer that the hemagglutination that is directed against Strain suppresses (HI) antibody; Several researchs have found that the HI titre that more old adult shows is lower than younger adult (Murasko, 2002, Experimental gerontology after the influenza immunity; 37,427-439).
The immunogenic novel vaccine that therefore, still need have improvement.Vaccine antigen is a kind of method that might strengthen the immunne response of subvirus isoantigen with the preparation of effective adjuvant.
Subunit influenza vaccines commercialization with the adjuvant MF59 adjuvantization of O/w emulsion form; Ability (De Donato etc., 1999, Vaccine that it induces the antibody titer that is higher than antibody titer that no adjuvant subunit vaccine obtains have been shown; 17,3094-3101).But, in publication afterwards, identical vaccine do not show its compare pattern that no adjuvant split vaccine improves (Puig-Barbera etc., 2004, Vaccine 23,283-289).
The influenza vaccines that still need improve are especially for elderly population.

Detailed Description Of The Invention
The inventor has been found that; Reply than what obtain with no adjuvant virus or its antigenicity prepared product; Contain influenza virus and antigenicity prepared product thereof and can reply at the CD4 T-cellullar immunologic response and/or the B cell memory of anti-said antigen of philtrum improvement or antigenic composition, but said oil in water emulsion adjuvant contains metabolism oil, sterol such as alpha-tocopherol and emulsifying agent together with the influenza preparation of oil in water emulsion adjuvant.Require the preparation of protection to be advantageously used in the CD4-T cell response of inducing influenza, this is replied and can detect the influenza epi-position of being offered by MHC II quasi-molecule.The applicant finds now, and the immune system that the said preparation efficient targeting is cell-mediated is so that increase the reactivity (when inoculation and infection) to the influenza strain of homology and drift.
Of the present invention have adjuvant influenza compositions to have several advantages:
1) immunogenicity of improving: they allow the weak immunne response among the old people (more than 50 years old, common over-65s) is returned to visible level in youngster (antibody and/or t cell response);
2) the cross protection pattern of improving: increase the cross-protection of resistance different (drift) influenza strain;
3) they also allow to use the antigen dose of minimizing to obtain similar replying, and have therefore guaranteed the effectiveness that in emergency circumstances (for example is very popular) and increases.
Specifically, according to people's number of subjects purpose evaluation of satisfying the protective effect of influenza dependency, compositions of the present invention can provide better anti-influenza serum protective effect after the immunity again.And the compositions that the present invention uses can also be induced following trend: than no adjunvant composition, inoculate B cell memory behind the people experimenter first time and reply higherly, and the humoral response after inoculating is higher.
The inventor also can show; Than the individuality that obtains the protection antibody level with no adjunvant composition, require the adjunvant composition that has of protection can in more individuality, induce and keep resisting the protection antibody level (for example referring to table 43) of the whole 3 kinds of strains that exist in the vaccine.
Therefore, in another embodiment again, require the compositions of protection can guarantee the persistence immunne response of influenza relevant disease.Specifically, said persistence refer to that the HI antibody mediated immunity is replied can be after inoculation at least 3 months, preferably satisfy administrative standard after at least 6 months.Specifically; Require the compositions of protection to induce protection antibody level in the individuality>70% after at least 3 months, aptly in the individuality>80% or aptly in the individuality>90% at least a influenza strain that exists in the vaccine, preferred institute toxic strain.One concrete aspect, after inoculation, obtained at least 6 months to exist in the anti-vaccine combination at least a, aptly two kinds or all strains>90% protection antibody level.
Strains of influenza viruses and antigen
Influenza virus or its antigenicity prepared product can be cracking influenza virus or its lytic virus antigenicity prepared product used according to the present invention.In an alternate embodiment, the influenza virus prepared product can comprise the inactivation influenza antigens of another type, the for example HA of inactivation totivirus or purification and NA (subunit vaccine), or influenza virus particles.In another embodiment again, influenza virus can be attenuated live influenza virus prepared product.
Aptly, cracking influenza virus or its lytic virus antigenicity prepared product are inactivation virus prepared product used according to the present invention, and wherein virion destroys with detergent or other reagent of lipin dissolving peplos.Aptly; Lytic virus or its lytic virus antigenicity prepared product are prepared as follows: with the full influenza virus of organic solvent or the detergent fragmentation infectivity or the inactivation of concentration of ordinary dissolution, remove whole or most of lytic agents and some or most of viral lipid material subsequently.Said its lytic virus antigenicity prepared product refers to possibly stand purification to a certain degree with respect to lytic virus and has kept the lytic virus prepared product of most of antigenic characteristic of lytic virus component.For example, when in ovum, producing, lytic virus can be by removing in the ovum foreign protein, and when perhaps in cell culture, producing, lytic virus can be by removing in the host cell impurity.Lytic virus antigenicity prepared product can comprise the lytic virus antigenicity component of more than one Strain.The vaccine that contains the vaccine (being called ' cracking influenza vaccines ') of lytic virus or contain lytic virus antigenicity prepared product generally comprises remaining stromatin and nucleoprotein, comprises lipid and membrane envelope albumen sometimes.This split-virus vaccine comprises major part or whole virus structural proteins usually, but the ratio that not necessarily in totivirus, exists with them is identical.
Perhaps, influenza virus can be the whole virus vaccine form.For pandemicity, it can show the advantage that surmounts split-virus vaccine, because it has avoided the relevant uncertainty that whether can successfully produce split-virus vaccine to new strains of influenza viruses.For some strain, the conventional detergent that is used to produce lytic virus can damage virus, and makes it useless.Although often might use different detergents and/or develop different split vaccine production methods, this can be consuming time, maybe be unavailable under pandemicity.The totivirus method also has the production of vaccine ability bigger than lytic virus except largely the definitiveness, because in the essential additional purification step of the suitable split vaccine of preparation, quite a large amount of antigen losses is arranged.
In another embodiment, the influenza virus prepared product is the subunit influenza vaccines form of purification.The subunit influenza vaccines generally comprise two kinds of main envelope protein HA and NA, possibly have the additional advantage that surmounts totivirus body vaccine, because their general reactionless originality, especially in the inoculator of youth.But the subunit vaccine recombinant production perhaps can be by disruptive virion purification.
In another embodiment, the influenza virus prepared product is the virion form.Virion is spheric unilamellar vesicle, and it has kept the functional viral envelope glycoprotein HA and the NA of true conformation, inserts in the phospholipid bilayer film of virion.
That said influenza virus or its antigenicity prepared product can be the ovum source or the tissue culture source.
For example, influenza antigen of the present invention or its antigenicity prepared product can derive from conventional embryonated egg method, and this method is cultivated influenza virus in ovum, and the allantoic fluid of purification collection.Ovum can be accumulated at short notice in a large number.Perhaps, they can derive from the new production process of any using-system culture, to cultivate virus or express recombinant influenza virus surface antigen.Be suitable for cultivating viral cellular matrix and comprise for example MDCK; For example MDCK or MDCK clone cell, MDCK like cell; MK cells, for example the AGMK cell comprises the Vero cell; Suitable pig cell system, or be suitable for producing any other mammalian cell types of the influenza virus of vaccine use.Suitable cellular matrix also comprises people's cell, for example the MRC-5 cell.Suitable cellular matrix is not limited to cell line; For example naive cell like little CEF, also comprises avian cell lines.
Influenza antigen or its antigenicity prepared product can be through any productions in numerous business methods, for example in the middle cracking influenza virus method of describing of patent No. DD 300833 and DD 211444 (being attached among this paper by reference).The cracking influenza virus uses solvent/detergent treatment to produce traditionally, for example TRI N BUTYL PHOSPHATE, perhaps diethyl ether combination Tween TM(being called " Tween-ether " cracking), this method is still used in some manufacturer.Other decomposition agent that uses at present comprises detergent or proteolytic enzyme or bile salts, the NaTDC of for example in patent No. DD155875 (being attached among this paper by reference), describing.The detergent that can be used as decomposition agent comprises cationic detergent, for example cetrimide (CTAB); Other ion detergent, for example lauryl sulfate, taurodeoxycholate; Or nonionic detergent, as above-mentioned a kind of, comprise Triton X-100 (for example at Lina etc., 2000, Biologicals 28, in the method that 95-103 describes) and Triton N-101; The perhaps combination of any two or more detergents.
The method for preparing of split vaccine can comprise numerous different filtrations and/or other separating step; Ultra centrifugal, ultrafiltration, band centrifugation and chromatography (for example ion exchange) step like various combinations; And optional for example employing heat, formaldehyde or β-propanoic acid lactone or ultraviolet deactivation step, it can carry out before or after cracking.Cracking process can be in batches, continuously or semi-continuous process carry out.The preferred cracking and the purification process that are used for the cracking immunogenic composition are described in WO02/097072.
Preferred cracking influenza vaccines antigen preparation thing of the present invention comprises the Tween 80 and/or the Triton X-100 of the remaining residual volume of production process, but these materials can add or adjust its concentration after the cracking antigen preparation.Preferably, Tween 80 exists with Triton X-100.The preferable range of the final concentration of these nonionic surfactant is in the vaccine dose: Tween 80:0.01-1%, more preferably from about 0.1% (volume)
Triton X-100:0.001-0.1% (weight/volume), more preferably 0.005-0.02% (weight/volume).
In a specific embodiments, the final concentration of Tween 80 is in the scope of 0.045%-0.09% (weight/volume).In another embodiment; Antigen provides as 2 times of spissated mixture; Its Tween that has 80 concentration must be used 2 times of adjuvant (or in control formulation, using buffer) dilutions when final preparation in the scope of 0.045%-0.2% (weight/volume).
In another embodiment, the final concentration of Triton X-100 is in the scope of 0.005%-0.017% (weight/volume).In another embodiment; Antigen provides as 2 times of spissated mixture; The Triton X-100 concentration that it has must be used 2 times of adjuvant (or in control formulation, using buffer) dilutions when final preparation in the scope of 0.005%-0.034% (weight/volume).

etc.But specially suitable metabolism oil is zamene.Zamene (2,6,10,15,19; 23-hexamethyl-2,6,10,14,18; 22-tetracosa carbon six alkene) being a kind of unsaturated oils, being present in a large number in the shark liver oil, be present on a small quantity in olive oil, wheat germ oil, Testa oryzae oil and the yeast, is to be used for preferred especially oil of the present invention.But zamene is a metabolism oil because of the following fact: it is the biosynthetic intermediate of cholesterol (Merck index, the 10th edition, an entry number 8619).
O/w emulsion is from well-known in this area, shown to can be used as adjunvant composition (EP 399843; WO 95/17210).
Aptly, but metabolism oil exist with the amount of 0.5% to 20% (final concentration) of immunogenic composition cumulative volume, preferably 1.0% to 10% amount with cumulative volume exists, preferably 2.0% to 6.0% amount with cumulative volume exists.
In a specific embodiments, but metabolism oil exists with about final quantity of 0.5%, 1%, 3.5% or 5% of immunogenic composition cumulative volume.In another embodiment, but metabolism oil exist with about final quantity of 0.5%, 1%, 3.57% or 5% of immunogenic composition cumulative volume.
Preferably, O/w emulsion of the present invention system has the little oil droplet granularity of sub-micrometer range.Aptly, the diameter of oil droplet is in the scope of 120-750nm, and more preferably diameter is in the scope of 120-600nm.Most preferably, O/w emulsion comprises oil droplet, and the diameter of its at least 70% (with intensitometer) is lower than 500nm, and more preferably the diameter of at least 80% (with intensitometer) is lower than 300nm, and more preferably the diameter of at least 90% (with intensitometer) is in the scope of 120-200nm.
Oil droplet granularity of the present invention, promptly diameter provides with intensity.There is several method to measure droplet diameter size with intensitometer.Intensity uses particle size measuring instrument to detect, and detects through the dynamic light scattering such as Malvern Zetasizer 4000 or preferred Malvern Zetasizer 3000HS aptly.Detailed method provides at example II .2.First probability is to measure z average diameter ZAD through dynamic light scattering (PCS-photon correlation spectroscopy method); The extra polydispersity index (PDI) that provided of this method, ZAD and PDI this two all use the cumulant algorithm computation.These values do not need the information of particle refractive index.Second method is to measure full particle size distribution through another kind of algorithm Contin or NNLS or automatization " Malvern " method (default algorithm that is provided by particle size measuring instrument) to calculate droplet diameter.Mostly the particle refractive index owing to the complex combination thing is unknown under the situation, thus can only consider intensity distributions, if needs are arranged, by this acquisition average strength that distributes.
O/w emulsion comprises sterol.Sterol is well-known in this area, and for example cholesterol is known, for example is disclosed in Merck Index, the 11st edition, 341 pages, is naturally occurring sterol in the Animal fat.Other suitable sterol comprises cupreol, stigmasterol, ergosterol, alpha-tocopherol and ergocalciferol.Said sterol exists with the amount of 0.01% to 20% (weight/volume) of immunogenic composition cumulative volume aptly, and preferably the amount with 0.1% to 5% (weight/volume) exists.Preferably; When sterol is cholesterol; Its amount with 0.02% to 0.2% (weight/volume) of immunogenic composition cumulative volume exists; More preferably the amount with 0.02% (weight/volume) of 0.5ml vaccine dose volume exists, and perhaps the amount with 0.07% (weight/volume) of 0.5ml vaccine dose volume exists, and perhaps the amount with 0.1% (weight/volume) of 0.7ml vaccine dose volume exists.
Aptly, sterol is the alpha-tocopherol or derivatives thereof, for example the alpha-tocofecol succinic acid ester.Preferably; Alpha-tocopherol exists with the amount of 0.2% to 5.0% (volume) of immunogenic composition cumulative volume; More preferably the amount with 2.5% (volume) of 0.5ml vaccine dose volume exists; Perhaps the amount with 0.5% (volume) of 0.5ml vaccine dose volume exists, and perhaps exists with the 1.7-1.9% (volume) of 0.7ml vaccine dose volume, preferred 1.8% amount.For the purpose of distinct, the concentration that provides with volume can change the concentration of representing with weight/volume into through using following conversion coefficient: 5% (volume) alpha-tocopherol concentration equals 4.8% (weight/volume) alpha-tocopherol concentration.
O/w emulsion also can contain emulsifying agent.Amount that can 0.01-5.0% with immunogenicity composition weight meter (w/w) emulsifying agent exists, and (w/w) exists with the amount of 0.1-2.0% preferably by weight.Weight preferred concentrations in total compsn is 0.5-1.5% (w/w).
Emulsifying agent can be suitably Tween-81 (Tween 80).In a specific embodiments, 0.5ml vaccine dose volume contains 1% (w/w) Tween80, and 0.7ml vaccine dose volume contains 0.7% (w/w) Tween 80.In another embodiment, the concentration of Tween 80 is 0.2% (w/w).
Oil in water emulsion adjuvant can be used for other adjuvant or immunostimulant, but therefore important embodiment of the present invention is the oil-in-water preparation that contains zamene or another kind metabolism oil, alpha-tocopherol and tween 80.O/w emulsion also can comprise span 85 and/or lecithin.Typically, oil-in-water comprises the zamene of the 2-10% of immunogenic composition cumulative volume, the alpha-tocopherol of 2-10% and the Tween of 0.3-3% 80, and can be according to the method production of describing among the WO 95/17210.Preferably, zamene: the ratio of alpha-tocopherol is equal to or less than 1, because it provides more stable emulsion.Span 85 (Tween-85) also can be for example exists with 1% level.
The immunogenicity characteristic that is used for the immunogenic composition that the present invention inoculates for the first time
In the present invention; Than the CD4 T-cellullar immunologic response that the corresponding compositions (this paper is called ' common compositions ') with no adjuvant (promptly not containing any external source adjuvant) obtains, the influenza compositions can be induced the CD4 T-cellullar immunologic response of the improvement of anti-at least a composition antigen or antigenic composition.
Said ' the CD4 T-cellullar immunologic response of improvement ' refers to that the CD4 that after adjuvant immunity originality compositions is arranged, in human patients, obtains replys and is higher than the immunne response that obtains behind the same combination that is not having adjuvant.For example; With do not have after immunogenic composition adjuvant, that contain influenza virus or its antigenicity prepared product inductive replying and compare; When containing influenza virus or its antigenicity prepared product, in human patients, obtain higher CD4 T-cell response, but said oil in water emulsion adjuvant comprises metabolism oil, sterol such as alpha-tocopherol and emulsifying agent together with the immunogenic composition of oil in water emulsion adjuvant.This preparation will be advantageously used in the CD4-T cell response of inducing resisiting influenza virus, and this is replied and can detect the influenza epi-position of being offered by MHC II quasi-molecule.
Preferably, by being used for of the present inventionly having the inductive said immunne response of adjuvant cracking influenza virus compositions to be higher than with the inductive immunne response of any other no adjuvant normal flow influenza vaccine (for example subunit influenza vaccines or full influenza virus vaccine).
Particularly but not exclusively, acquisition among said ' the CD4 T-cellullar immunologic response of improvement ' patient's (being seronegative patient promptly) of on immunology, just exempting to said influenza virus or antigen.This seronegativity possibly be never in the face of this virus or antigenic said patient's (so-called ' originally ' patient) result, is the said patient's that when meeting with, can not reply said antigen result perhaps substitutingly.Preferably; The CD4 T-cellullar immunologic response of said improvement obtains in the impaired experimenter of immunne response; The impaired experimenter of said immunne response for example is the old people; Be generally 65 years old or more than, or have the excessive risk medical conditions less than 65 years old adult (' excessive risk adult '), or the child below 2 years old.
The CD4 T-cellullar immunologic response that improves can be estimated through detecting the cell number that produces any following cytokine:
Produce the cell of at least two kinds of different cytokines (CD40L, IL-2, IFN γ, TNF α)
Produce the cell of CD40L and another kind of cytokine (IL-2, TNF α, IFN γ) at least
Produce the cell of IL-2 and another kind of cytokine (CD40L, TNF α, IFN γ) at least
Produce the cell of IFN γ and another kind of cytokine (IL-2, TNF α, CD40L) at least
Produce the cell of TNF α and another kind of cytokine (IL-2, CD40L, IFN γ) at least
When with do not have adjunvant composition and compare the cell concentration that produces any above cytokine after adjunvant composition is being arranged when higher, with the CD4 T-cellullar immunologic response that has improvement.Usually, at least a, preferred two kinds in 5 kinds of situations mentioning of preceding text will be implemented.In a specific embodiments, compare with no adjuvant group, there is in the adjuvant group cell of producing whole 4 kinds of cytokines to exist with a large amount more.
In fact can give the back at single by the CD4 T-cellullar immunologic response that the improvement that adjuvant influenza compositions gives arranged of the present invention obtains.For example earthshaking meaning will be arranged at the outburst situation of the fast development agent method that places an order.In some cases, especially for elderly population, perhaps for the child (below 9 years old) of the inoculation of influenza first, give two doses identical this in season compositions possibly be useful.Second dose of said same combination (still being counted as ' compositions that is used for inoculating first ') can give in the process that initial immunne response is developing, and has time enough at interval.Usually, second dose of compositions gives several weeks or about 1 month (for example 2 weeks, 3 weeks, 4 weeks, 5 week or 6 weeks) after first dose, to help to trigger the immune system in no response or the low responder.
In a specific embodiments; Reply with inductive B memory cell in no adjunvant composition immune body and to compare, give said immunogenic composition and in the patient that adjuvant immunity originality compositions is arranged, alternatively or extraly induce the B-memory cell of improvement to reply.The B-memory cell that improves is replied to mean and when meeting with antigen, can be divided into the lymphocytic frequency of the plasmacytic peripheral blood B of antibody-secreting property and increase, and this stimulates and detect (referring to the embodiment part, for example the method for Elispot B cell memory) through vitro differentiation.
In another specific embodiments again, with the compositions inoculation CD8 is replied no detectable influence with the inoculation first that adjuvant is arranged.
The applicant is surprisingly found out that; Contain with the influenza virus of oil in water emulsion adjuvant preparation or compositions effective promotion t cell response in the immunocompromised host crowd of its antigenicity prepared product, but said oil in water emulsion adjuvant comprises metabolism oil, sterol such as alpha tocopherol and emulsifying agent.The applicant shows; According in elderly population, carrying out the relatedness evaluation that influenza inoculates back influenza vaccines protective effect; Compare with the serum protection that provides with no adjuvant influenza vaccinations, give single agent such as of the present invention the inoculation first can provide better serum protection with immunogenic composition.Than the immunne response that no adjuvant formulation obtains, require the adjuvant formulation that has of protection can also induce the CD4 T-cellullar immunologic response of the improvement of resisiting influenza virus.The responsiveness that this observed result increases in the time of maybe be with inoculation or in the face of the infection of influenza antigens property contact is relevant.And it also maybe be relevant with cross reactivity, and the ability that promptly strain is replied to the variant influenza is higher.Replying of this improvement maybe be useful especially in the crowd of immunocompromised host such as elderly population (65 years old with more than) and especially excessive risk elderly population.This can cause reducing whole M & M, and prevents promptly being admitted to hospital of pneumonia and other influenza appearance disease.This also can be useful to infant population (below 5 years old, preferred below 2 years old).And, and to compare with inductive the replying of no adjuvant formulation, it allows the more persistent CD4 t cell response of induction time, for example still has 1 year after the inoculation first.
Preferably, CD4 T-cellullar immunologic response for example at the CD4 T-cellullar immunologic response of the improvement of just not exempting to obtain among the experimenter, comprises that inducing cross reactivity CD4 T to assist replys.Specifically, the amount of cross reactivity CD4 T cell increases.Said ' cross reactivity ' CD4 replys the total epi-position that refers between the strain of CD4 T-cell-targeting influenza.
Usually, available influenza vaccines are only effectively resisted the influenza infection strain of the hemagglutinin with similar antigenicity characteristic.When infecting minor variations (the for example accumulation of point mutation or point mutation that (circulation) property influenza virus has experienced surface glycoprotein (hemagglutinin specifically); Cause amino acid change) time (antigenic drift variant Strain); Vaccine still can provide some protective effects; But it possibly only provide limited protective effect, because the new variant that produces possibly escaped previous influenza infection or inoculate inductive immunity.Antigenic drift be the annual popular reason that takes place during being very popular for twice (Wiley&Skehel, 1987, Ann.Rev.Biochem.56,365-394).Inducing to the present composition of cross reactivity CD4 T cell provides extra advantage; Because it also can provide cross-protection; In other words be the protective effect that anti-allos infects; Said allos infects the infection that is promptly caused by the circulation strains of influenza viruses, and this circulation strains of influenza viruses is the variant (variant for example drifts about) of the strains of influenza viruses that comprises in the immunogenic composition.This possibly be favourable when the circulation strain is difficult in ovum, breed or is difficult in tissue culture, produce, and makes the drift strain as alternative work strain.This accepts for the first time with some months or 1 year the experimenter at interval also maybe be favourable when inoculating for the second time, is used for the influenza strain of the immunogenic composition of immunity for the second time and is the drift variant strain of the strain that the compositions that is used for inoculating first uses.
Detection with cross reactivity CD4 T-cell after the influenza vaccinations
After giving classical trivalent influenza vaccines (3 week); The frequency of the peripheral blood CD4 T-cell that antigenicity strain prepared product (totivirus or cracking antigen) is replied significantly increases, a kind of antigen that exists in said antigenicity strain prepared product and the vaccine (H3N2:A/ Panama/2007/99; H1N1:A/ New Caledonia/20/99; B:B/ Shandong/7/97) (referring to EXAMPLE III) homology.If the influenza strain with being categorized as drift strain (H3N2:A/ Sydney/5/97, H1N1:A/ Beijing/262/95, B:B/ Pyrusussuriensis/166/98) stimulates peripheral blood CD4 T-cell again, then can see sizable frequency increases.
On the contrary, if be categorized as drift strain (H2N2:A/ Singapore/1/57 with the expert of the art; H9N2:A/ Hong Kong/1073/99) influenza strain stimulates peripheral blood CD4 T-cell again, then after inoculation, does not have observable increase.
The CD4 T-cell of influenza strain that can discern homology and drift simultaneously called after " cross reactivity " in presents.Require the adjuvant influenza compositions that has of protection purposes in the present invention can demonstrate the cross reactivity of different hypotype, because there is the observable cross reactivity of anti-drift influenza strain.
Consistent with above observed result, identify different influenza strains total CD4T-cell epitope (Gelder C etc., 1998, Int Immunol.10 (2): 211-22 at philtrum; Gelder CM etc., 1996 J Virol.70 (7): 4787-90; Gelder CM etc., 1995 J Virol.199569 (12): 7497-506).
In a specific embodiments; There is adjunvant composition that additional benefit can be provided; These interests provide the better protective effect of anti-circulation strain; Said circulation strain has experienced the about-face (for example gene recombinaton, the for example gene recombinaton between two different plant species) (antigenic drift) of hemagglutinin, and present available vaccine is invalid to it.

Perhaps, at least a strain is relevant with the outburst of being very popular, and perhaps has and the relevant potentiality of outburst that are very popular.
As a setting, in the time period between being very popular, with the relevant transmission of influenza virus of pandemic influenza virus before.Virus is propagated between the people with the immunity level different with the life early infection.In the time period of common 2-3, this propagation promotes changing to such an extent that be enough in general groups, cause the selection of epiphytotics new strain again; This process is called ' antigenic drift '.' drift variant ' all had Different Effects in different communities, area, country or continent in arbitrary year, although its general impacts often are similar in several years.In other words, when the crowd occurring it is not had the new influenza virus of immunity, flu outbreak takes place.Typical flu outbreak causes that the sickness rate of pneumonia and lower respiratory illness increases, and evidence is that admission rate or mortality rate increase.Old people or the people who suffers from basic chronic disease most possibly experience this complication, and the child also possibly suffer from serious disease.
New influenza virus in unpredictalbe interval, occurs, it has the critical surfaces antigenemia cell agglutinin with the complete different subtype of strain that seasonal current is capable before.At this moment, the antigen of generation can have 20% to 50% variation with previous corresponding albumen in philtrum circulation strain.This can cause viral escape ' herd immunity ', and generation is very popular.This phenomenon is called ' antigen conversion '.It is generally acknowledged that taken place at least in the past to be very popular, the influenza virus of different plant species such as fowl or swine influenza virus had passed species barrier at that time.If these viruses have the potentiality of interpersonal propagation, they can whole world diffusion in several months to one year, causes being very popular.For example, nineteen fifty-seven (Asia influenza is very popular), the H2N2 subtype virus has replaced H1N1 virus, and H1N1 virus just circulates among the crowds from the beginnings in 1918 that at first are separated to this virus at least.H2HA and N2 NA have experienced antigenic drift between nineteen fifty-seven to nineteen sixty-eight; The H3N2 influenza virus sub-strain that is occurred in nineteen sixty-eight (Mao flu is very popular) until HA substitutes, and after this N2 NA continues drift (Nakajima etc., 1991 together with H3 HA; Epidemiol.Infect.106,383-395).
Giving its strains of influenza viruses characteristic that causes the outbreak potential that is very popular is: compare it with the hemagglutinin in the current circulation strain and comprise new hemagglutinin, its can with or without the change of neuraminidase hypotype; It can be in the crowd horizontal transmission; It is morbific to the people.New hemagglutinin can be (possible many decades) also unconspicuous hemagglutinin, for example H2 in the crowd in long-time section.It does not also have circulation hemagglutinin in the crowd, the H5 that for example in bird, finds, H9, H7 or H6 before perhaps can be.Under any situation, most of or at least vast scale so that whole colony all do not run into antigen in the past, on immunology, be former initial state to antigen.
In general, under the environment that is very popular, some colony is increased by the risk of influenza infection.Old people, chronic disease and child be susceptible especially, but many youngsters are also risky with surperficial healthy people.For the H2 influenza, the risk that the partial mass of being born after nineteen sixty-eight bears increases.These colonies are importantly protected as soon as possible and with simple mode effectively.
Another crowd who bears the risk of increase is the traveller.Today, whenever people than travelling more often in the past, and area China and Southeast Asia that maximum new virus occur have become welcome Reiseziel in recent years.This change of communication mode can make new virus in about several weeks rather than in several months or several years, arrive the whole world.
Therefore, for these crowds, need the inoculation protection to come under pandemicity or under potential pandemic situation especially to influenza.Suitable strain is but is not limited to: H5N1, H9N2, H7N7, H2N2 and H1N1.
Perhaps, said compositions can comprise more than 3 valencys, and for example two kinds of non-strains that are very popular add a kind of strain that is very popular.Perhaps, said compositions can comprise 3 kinds of strains that are very popular.
In a further embodiment; The present invention relates to a kind of vaccination regimen; Wherein inoculation first uses the cracking influenza compositions that contains at least a influenza strain to carry out; Wherein said influenza strain can cause the outburst of being very popular potentially, inoculates to use perhaps perhaps to carry out for the circulation strain of classical strain as epidemic strain.
CD4 epi-position among the HA
This antigenic drift mainly is present in the epi-position district of virus surface proteins hemagglutinin (HA) and neuraminidase (NA).Knownly be used for escaping that any difference of CD4 and B cell epitope all will play an important role in the influenza inoculation between the different influenza strains that the adaptability of host immune system replys by virus, and like this really.
Identify the total CD4 T-cell epitope of different influenza strains (referring to for example: Gelder C etc., 1998, Int Immunol.10 (2): 211-22 at philtrum; Gelder CM etc., 1996 JVirol.70 (7): 4787-90; With Gelder CM etc., 1995 J Viroi.1995 69 (12): 7497-506).
In a concrete embodiment; Inoculate and use the reinforcement compositions that contains influenza virus or its antigenicity prepared product to carry out, said influenza virus or its antigenicity prepared product and influenza antigen that is used for inoculation for the first time or the total common CD4 T-cell epitope of its antigenicity prepared product.Therefore; The immunogenic composition that the present invention relates to contain influenza virus or its antigenicity prepared product and oil in water emulsion adjuvant is inoculated the purposes in the component first what produce the multiple dose vaccine; But said oil in water emulsion adjuvant contains metabolism oil, sterol such as alpha-tocopherol and emulsifying agent; Said multiple dose vaccine also comprises as the influenza virus of booster dose or its antigenicity prepared product, the total common CD4 T-cell epitope of the influenza antigen of the dosage that gives or its virus antigenicity prepared product when they were inoculated with the first time.
Inoculation method
Compositions of the present invention can give through any suitable pipeline, for example Intradermal, mucosa such as intranasal, oral, intramuscular or subcutaneous.Other pipeline is well-known in this area.
The intramuscular pipeline is preferred to adjuvant influenza compositions is arranged.
Intradermal delivery is another suitable approach.Any suitable device all can be used for intradermal delivery, for example at US 4,886, and 499, US 5,190,521, US 5; 328,483, US5,527,288, US 4,270,537, US 5; 015,235, US 5,141, and 496, the hour hand device described among the US 5,417,662.Intradermal vaccine also can give through the device that the restriction pin gets into effective penetration length of skin, for example is described in device and the function equivalent thereof of WO99/34850 and EP1092444, and these two documents are attached among this paper by reference.Rapid injection device also suits, its through liquid fast injection device or through the effusive pin transmit fluid vaccine that pierces through horny layer and produce to arrive corium to corium.Rapid injection device is described in for example US5, and 480,381, US 5,599,302, US 5,334,144, US 5,993; 412, US 5,649, and 912, US 5,569,189, US 5,704,911, US 5,383; 851, US 5,893, and 397, US5,466,220, US 5,339,163, US 5,312; 335, US 5,503, and 627, US 5,064,413, US 5,520,639, US 4,596; 556, US 4,790, and 824, US 4,941,880, US4,940,460, WO 97/37705 and WO 97/13537.Pulverized powder/granule transfer device also suits, and it uses the vaccine of Compressed Gas powder quick form to pass through skin outer layer to corium.In addition, conventional syringe can be used for the classical Mantoux test method that Intradermal gives.
The approach that gives that another is suitable is a subcutaneous route.Any suitable device all can be used for subcutaneous transmission, for example classical pin.Preferably, use for example disclosed needleless fast injection device service in WO 01/05453, WO01/05452, WO 01/05451, WO 01/32243, WO 01/41840, WO 01/41839, WO 01/47585, WO 01/56637, WO 01/58512, WO 01/64269, WO01/78810, WO 01/91835, WO 01/97884, WO 02/09796, WO 02/34317.More preferably, said device is filled with liquid vaccine preparation in advance.
Perhaps, the vaccine intranasal gives.Typically, the vaccine topical administration preferably is not drawn in the lung in nasopharynx part.It is desirable to use bacterin preparation is transmitted into nasopharynx part and does not have or do not make it get into the intranasal transfer device in lung basically.
It is sprayer unit that the preferred intranasal of vaccine of the present invention gives device.Suitable commercial nose sprayer unit comprises Accuspray TM(Becton Dickinson).Nebulizer produces very tiny droplet, and it can be drawn in the lung easily, therefore can not effectively arrive nasal mucosa.Therefore not preferred nebulizer.
The preferred spray devices that is used for the intranasal purposes is the device of the pressure independent that provides of performance and user.These devices are called pressure territory device.Only, critical pressure just discharges liquid when being provided by nozzle.These devices obtain the spraying of drop size rule more easily.Be applicable to that pressure of the present invention territory device is known in this area, be described in for example WO 91/13281 and EP 311 863 B and EP 516 636, these documents are attached among this paper by reference.This device can be bought by Pfeiffer GmbH, also is described in Bommer, R.PharmaceuticalTechnology Europe, in JIUYUE, 1999.
Drop (water is detected as the liquid) scope that preferred intranasal device produces is 1-200 μ m, preferred 10-120 μ m.Have the suction risk less than 10 μ m, the drop that therefore it is desirable to below the 10 μ m is no more than about 5%.The above drop of 120 μ m spread not as less drop good, be no more than about 5% so it is desirable to the above drop of 120 μ m.
The dose double transmission is the more preferably characteristic that is used for the intranasal transmission system of vaccine of the present invention.The dose double device comprises two sub-doses of single vaccinating agent, and each nostril gives a sub-doses.In general, two sub-doses are present in the container, and the structure of device allows each single sub-doses that effectively transmits.Perhaps, can use single dose device to give vaccine of the present invention.
Perhaps, the present invention has also imagined epidermis or transdermal route of inoculation.
In a specific embodiments of the present invention, but the adjuvant immunity originality compositions intramuscular that has that gives first give, the reinforcement compositions that adjuvant is arranged or do not have an adjuvant can give through different approaches, for example Intradermal, subcutaneous or intranasal.In another embodiment, the compositions that gives first can comprise the standard HA content of each influenza strain 15 μ g, strengthens the HA that compositions can comprise low dosage, promptly is lower than 15 μ g, and can smaller size smaller gives according to the approach of giving.
Inoculation colony
The target group of inoculation can be the people of immunocompromised host.Compare with health adult, the people of immunocompromised host generally can not reply antigen, especially influenza antigens well.
Preferably, target group are the colonies that influenza just do not exempted from, and (for example with respect to the strain that is very popular) of they or former initial state perhaps before can not be replied influenza infection or inoculation.Preferably, target group are old peoples, be suitably 65 years old with more than; Younger excessive risk adult (be 18-64 year) is for example the people of health institution's work; The Young Adults that perhaps has high risk factor such as cardiovascular diseases and pneumonopathy or diabetes.Another target group are all 6 months children with above child, an especially 6-23 monthly age, and they have experienced the high relatively influenza admission rate of being correlated with.Preferably, target group are old peoples of over-65s.
Vaccination regimen, administration and additional effect standard
Aptly, immunogenic composition of the present invention is standard 0.5ml ID under most of situation, according to spreading (SRD) (J.M.Wood etc.: J.Biol.Stand.5 (1977) 237-247 according to single radiation immunity; J.M.Wood etc., J.Biol.Stand.9 (1981) 317-330) detect, contain 15 μ g hemagglutinin antigen components of each influenza strain.Aptly, the vaccine dose volume between 0.5ml to 1ml, specifically standard 0.5ml or 0.7ml vaccine dose volume.According to the HA concentration in the stock solution sample, can slightly adjust dose volume routinely.
Aptly, said immunogenic composition contains HA antigen-for example every influenza strain 1,2,3,4,5,6,7,8,9,10,11,12,13 of low dosage or any among the 14 μ gHA.Suitable low dosage HA between every influenza strain 1-7.5 μ gHA, aptly between every influenza strain 3.5-5 μ g HA, for example every influenza strain 3.75 μ g HA, typically every approximately influenza strain 5 μ gHA.
Advantageously, vaccine dose of the present invention, especially low dosage vaccine can be to provide than the little volume of routine injection cracking influenza vaccines that is generally every dose about 0.5,0.7 or 1ml.Small size dosage of the present invention preferred every dose less than 500 μ l, more preferably every dose less than 300 μ l, most preferably every dose is no more than about 200 μ l or following.
Therefore, be the dosage that in small size, has low antigen dose according to the preferred small size vaccine dose of one aspect of the invention, 15 μ g or about 7.5 μ gHA or about 3.0 μ g HA (every strain) for example have an appointment in about 200 μ l volumes.
Influenza medicine of the present invention preferably satisfies some international standard of vaccine.
Proposed to detect the standard that influenza vaccines are renderd a service in the world.The European Union's official standard that in following table 1, has shown effective influenza vaccine.In theory, for satisfying European Union's requirement, all influenza strains that in vaccine, comprise, influenza vaccines only need be satisfied a standard in the table.Compositions of the present invention satisfies at least one in these standards aptly.
Yet in practice, all Strain must satisfy at least two or whole three in the said standard, particularly for new generation vaccine (new generation vaccine that for example transmits through different approaches).In some cases, two standards maybe be enough.For example, can accept all Strain and satisfy two in three standards, and part but be not that whole Strain satisfy the 3rd standard (for example two kinds in three kinds of Strain).Requirement to adult colony (18-60 year) and old people colony (greater than 60 years old) is different.

Until attacking back 5 days per 15 minutes record temperature, calculate meansigma methods preceding 3 days of attack by Japan and China.The result of baseline to baseline body temperature is shown in Figure 10 A (having shown-1 to+3 days result) and 10B (having shown-2 to+3 days result).
After attack, only after with common vaccine of trivalent cracking or PBS immunity, observe the body temperature peak value.After trivalent split vaccine immunity, do not observe peak value with AS03 or AS03+MPL adjuvantization.
V.3.2. virus shedding (Figure 11)
Every group of 6 animals are carried out the titration of virus of nose cleanout fluid.
Carry out the nose cleaning through in two nostrils of clear-headed animal, giving 5ml PBS.Inoculum is collected in the culture dish, and places the shuttle of-80 ℃ (dry ice).
All nose samples are all at first through Spin X filter (Costar) aseptic filtration, to remove any germ contamination.The nose cleanout fluid of the continuous 10 times of dilutions of 50 μ l is transferred in the microtitration plate that contains 50 μ l culture medium (10 holes/dilution factor).Then with 100 μ l mdck cells (2.4 * 10 5Individual cell/ml) adds each hole, and in 35 ℃ of incubations, reaches cell until control cells and converge, for example 5-7 days.Behind 6-7 days incubations, take out culture medium carefully, add the culture medium that 100 μ l contain 1/20WST-1, incubation is 18 hours again.
The survivaling cell number that the intensity of the cured dyestuff of yellow first that when survivaling cell reduction WST-1, produces and titration of virus experiment are present in the hole when finishing is proportional, and quantitative through the absorbance that detects each hole at suitable wavelength (450nm).The intercepting value defined is not for infecting OD meansigma methods-0.3 OD (0.3 OD is equivalent to not infect control cells OD ± 3 standard deviation) of control cells.Be defined as negative score during OD <be defined as positive score during the intercepting value, on the contrary, OD>intercepting value.The virus shedding titre is measured through " Reed and Muench ", and is expressed as Log TCID 50/ ml.
Than common vaccine of trivalent cracking or PBS, after attacking, observe lower virus shedding with the trivalent split vaccine of AS03 or AS03+MPL adjuvantization.The protective effect of adopting AS03 is than AS03+MPL good slightly (referring to attacking the back the 2nd day).Because every group size of animal is few, so be not sure of significance,statistical.
V.3.3. experiment conclusion
Than the common vaccine of trivalent cracking, observe higher humoral response (HI titre) (2 kinds in 3 kinds of strains (being H3N2 and B strain) are at least 2 times) to whole 3 kinds of strains with the trivalent split vaccine of AS03 or AS03+MPL adjuvantization.
With regard to regard to the protection in the ferret is renderd a service, AS03 and AS03+MPL preparation demonstrate extra interests (lower virus shedding and temperature) (Figure 10 and 11).
After the attack, do not observe the reinforcement of humoral response after the trivalent split vaccine immunity with AS03 or AS03+MPL adjuvantization.

V.4. ultimate principle and target
This research has been studied the effectiveness that adjuvant is arranged or do not have the various trivalent split vaccines of adjuvant through ability that alleviates symptom (body temperature) and the effect that allos is attacked the virus shedding in the immune ferret nasal discharge in back thereof.
V.5. experimental design
(Hampshire UK) obtains the 14-20 female ferret (Mediterranean ferret (Mustela putorius furo)) (6 ferret/groups) in age in week by MISAY Consultancy.Test 4 groups:
*Fluarix
*Trivalent split vaccine AS03
*Trivalent split vaccine AS03+MPL
*PBS
Ferret at the 0th day with xenogenesis hypotype strain H1N1 A/ Stockholm/24/90 (4 LogTCID 50/ ml) just exempt from.At the 21st day, with the combination intramuscular injection ferret of H1N1 A/ New Caledonia/20/99 of total man's dosage (500 μ g vaccine doses, 15 μ g HA/ strains), H3N2 A/ Panama/2007/99 and B/ Shandong/7/97 (17.5 μ g HA).Passed through the intranasal approach with xenogenesis hypotype strain H3N2 A/ Wyoming/3/2003 (4.51 Log TCID at the 43rd day then 50/ ml) attack ferret.
V.6. result
Result's sketch map provides in Figure 12 and Figure 13.
V.6.1. temperature monitoring
During attacking, monitor a temperature with pick off and through tele rcording.The inspection and rebuild all implants, before putting into the abdominal cavity, newly calibrate through DSI.All animals all are housed in the independent cage independently between these detection periods.
Result (Figure 12) shows:
-in the high transmutability of just exempting between one group of front and back observation and another group.Baseline seems before just exempting from, to exempt from than just back high.
Although there is high transmutability in-body temperature, only in the ferret of PBS (6/6 ferret), the common vaccine of trivalent cracking (5/6 ferret) and AS03 adjuvant trivalent split vaccine (2/6 ferret) immunity, after attacking, observe peak value.After with the immunity of AS03+MPL adjuvant trivalent split vaccine, do not observe peak value (0/6 ferret).
-with regard to the heating prevention, it is effective that anti-allos strain AS03 seems to be not so good as AS03+MPL.We can not conclude that the adjuvant differences is the probability that comes from the preceding antibody horizontal of different attacks.
V.6.2. virus shedding (Figure 13)
Carry out the nose cleaning through in two nostrils of clear-headed animal, giving 5ml PBS.Inoculum is collected in the culture dish, and places the shuttle of-80 ℃ (dry ice).
All nose samples are all at first through Spin X filter (Costar) aseptic filtration, to remove any germ contamination.The nose cleanout fluid of the continuous 10 times of dilutions of 50 μ l is transferred in the microtitration plate that contains 50 μ l culture medium (10 holes/dilution factor).Then with 100 μ l mdck cells (2.4 * 10 5Individual cell/ml) adds each hole, and in 35 ℃ of incubations, reaches cell until control cells and converge, and for example reaches 5-7 days.Behind 6-7 days incubations, take out culture medium carefully, add the culture medium that 100 μ l contain 1/20 WST-1, incubation is 18 hours again.
The survivaling cell number that the intensity of the cured dyestuff of yellow first that when survivaling cell reduction WST-1, produces and titration of virus experiment are present in the hole when finishing is proportional, and quantitative through the absorbance that detects each hole at suitable wavelength (450nm).The intercepting value defined is not for infecting OD meansigma methods-0.3 OD (0.3 OD is equivalent to not infect control cells OD ± 3 standard deviation) of control cells.Be defined as negative score during OD <be defined as positive score during the intercepting value, on the contrary, OD>intercepting value.The virus shedding titre is measured through " Reed and Muench ", and is expressed as Log TCID 50/ ml.
Virus shedding after just exempting from
Detect and just exempt from preceding the 1st day to the virus shedding of just exempting from the 7th day 12 the blood ermines in back.The result representes with hybrid mode.
Virus sweep in the ferret is arranged just exempting from back 7 days observation stations.
Virus shedding after the attack
Detect 6 ferret/rents by attacking preceding 1 day to attacking back 7 days virus shedding.
Attacked back 2 days; Than ferret with common vaccine of trivalent cracking and PBS immunity; In ferret, observe significantly lower virus titer (compare with common vaccine, the difference of adjuvant group AS03/AS03+MPL is respectively 1.25/1.22 log and 1.67/1.64 log) of statistics with AS03 and the immunity of AS03+MPL adjuvant trivalent split vaccine.
At the 50th day, in the nose cleanout fluid, do not detect virus.
V.6.3. hemagglutination suppresses test (HI titre) (Figure 14 A and B)
Just exempt from preceding 1 day, just exempt from back 21 days, back 22 days of immunity and attack and collected blood serum sample in back 14 days.
Use hemagglutination inhibition test (HI) to measure anti-hemagglutinin antibody titer to H3N2 influenza virus (vaccine strain and attack strain).The HI testing principle is based on the specific anti influenza antibodies suppresses the hemagglutination of little chicken red blood cell (RBC) through influenza virus haemagglutinin (HA) ability.Serum at first uses 25% neuraminic acid enzymatic solution (RDE) to handle, and heat inactivation, to remove nonspecific inhibitor.After the pretreatment, with every kind of influenza strain incubation of 2 times of dilution serum and 4 HAUs.Add little chicken red blood cell then, and the record coagulation suppresses.Titre is expressed as the dilution inverse of the highest serum that suppresses hemagglutination fully.Because first serum dilution is 1: 10, so be to equal 5 titre with undetectable horizontal recording.
The result:
The result is shown in Figure 14 A and 14B.After with the immunity of H3N2 A/ Panama, the humoral response (HI titre) that in the ferret with AS03 or the immunity of AS03+MPL adjuvant trivalent split vaccine, observes is than using no adjuvant (common) trivalent split vaccine (Fluarix TM) humoral response that observes behind the immune ferret is high.
In the ferret immune, observe similar HI titre with H3N2 A/ Panama of AS03 or AS03+MPL adjuvantization.
Only behind the vaccine immunity that contains A/ Panama H3N2 strain, observe cross reactivity HI titre (after with the common vaccine immunity of trivalent cracking, not observing) to allos strain A/ Wyoming H3N2 with AS03 or AS03+MPL adjuvantization.
In with allos strain A/ Panama H3N2 immunity and ferret, observe the enhancing of A/ Wyoming specificity HI titre with A/ Wyoming H3N2 attack.As expect that attack on the contrary with homology, allos is attacked and caused with the Panamanian specificity HI of A/ titre increase in the ferret of A/ Panama H3N2 immunity of AS03 and AS03+MPL adjuvantization.
V.6.4. the conclusion that should test
As expect, compare with the situation (do not have and strengthen) after homology is attacked, after allos is attacked, observe the reinforcement of anti-H3N2 HI titre.
But, after allos and homology are attacked, observe similar protective effect (virus shedding).Example VI-have the influenza vaccines of adjuvant and no adjuvant just to exempt from clinical preceding evaluation the in the mice at C57BI/6
VI.1. experimental design and target
Common with Fluarix (no adjuvant) vaccine is compared, and in Explo-Flu-001 clinical research (referring to EXAMPLE III), observes to the CD4 t cell response of trivalent influenza split vaccine AS03 significantly higher.Between these two groups, do not observe the difference of CD8 T cell and humoral response this two.

XII.3. immunogenicity result
XII.3.1.CMI terminal point and result
The main terminal point of estimating
At the 21st day: in the test that produces at least two kinds of different cytokines (IL-2, IFN-γ, TNF-α and CD40L), according to per 10 6All experimenters' of influenza specific C D4 T-lymphocyte frequency CMI replys in the individual cell
Reply for estimating CMI, analyze the frequency of influenza specific C D4 as follows:
The ANCOVA model that use relates to the logarithmic transformation titre obtains the GM ratio according to influenza specific C D4 frequency between the group that Adjuvanted vaccines and Flu YNG inoculation is arranged.The ANCOVA model comprises as the vaccine group of fixed effect with as logarithmic transformation titre before the inoculation of regressor.GM ratio and 98.75%CI thereof derive from the exponential transform of correspondence group opposite in the model.The 98.75%CI of the GM of adjustment obtains through the exponential transform of the 98.75%CI of the group least square method of above ANCOVA model.
The result- Rational analysis (table 47)
After the external stimulation again with " antigen II of merging ", the lymphocytic adjustment back GM of influenza specific C D4 T-and the GM ratio (and 98.75%CI) that produced at least two kinds of cytokines (IL-2, IFN-γ, TNF-α and CD40L) in the 21st day are shown in table 47.The adjuvant influenza vaccines are arranged for every kind, the upper limit of the bilateral 98.75%CI of GM ratio is far below 2.0 clinical limit.This has shown the Fluarix that gives than in the 18-40 adult in year TMTwo kinds of giving to old experimenter of vaccine have the non-bad effect property of adjuvant influenza vaccines with regard to frequency after the inoculation of influenza specific C D40.

The result- Descriptive analysis (Figure 26)
The main discovery is:
If CMI replys in youngster than in the old people high before the inoculation
After the inoculation,
Zero influenza vaccines have been replied booster action to the CMI in the Young Adults (18-40 year)
Zero CMI in the old people who accepts the adjuvant influenza vaccines reply with Young Adults in CMI reply quite.
When we contrast Fluarix (18-40 year) and FlU/AS03+MPL (concentration 1), except IFN γ, for all tests, with Fluarix TM(18-40 year) compares, and the difference of CD4 T lymphocyte responses that is directed against all cells factor of being studied (IL-2, CD40L, TNF-α and IFN-γ) before the inoculation and between the inoculation back is all significantly higher when employing has Adjuvanted vaccines.
Should be pointed out that stimulated in vitro with Flu strain (i) B/ Jiangsu, (ii) A/H3N2/ New York and (iii) the A/H3N2/ Wyoming carry out, rather than be included in the A/H1N1/ New Caledonia in the vaccine.But the preliminary data that comprises from a part of experimenter's A/H1N1/ New Caledonia vaccine strain shows that the result is similar.
The result- Estimate the 3rd terminal point (table 48)
In order to estimate the 3rd terminal point, detected the frequency of influenza specific C D4/CD8 T-lymphocyte and memory B cell at the 0th, 21,90 and 180 day.
Summed up for every kind of antigen, each vaccine group the influenza specific cell factor lymphocytic frequency of male CD4/CD8 T-(descriptive statistics) at the 0th and 21 day.
The local difference that non parametric tests (Wilcoxon check) is used to contrast between two groups (has the adjuvant influenza vaccines to Fluarix TM), calculate in each test to every kind of antigenic statistical p-value.In each test, calculate 21 days/0 day descriptive statistics of replying individual variation between (before the inoculation back/inoculation) to each inoculation group and every kind of antigen.
Non parametric tests (Wilcoxon check) is used to contrast individual variation (inoculation before the inoculation back/inoculation), calculates every kind of antigenic statistical p-value in each different check.
The p-value that is used to contrast the Wilcoxon check of influenza specific C D4 T-lymphocyte frequency difference is shown in table 48.

Group 1: with the influenza vaccines (concentration 1) of AS03+MPL adjuvantization
Group 2: with the influenza vaccines (concentration 2) of AS03+MPL adjuvantization
Main Conclusions is:
(a) the GM frequency all is similar in all old subject group before the inoculation of influenza specific C D4, but more excellent in the adult in 18-40 year.
(b) in the old experimenter that the Adjuvanted vaccines inoculation is arranged and at Fluarix TMAmong the 18-40 year adult of inoculation, the lymphocytic inoculation of influenza specific C D4 T afterwards (the 21st day) frequency is similar.
(c) and Fluarix TMCompare, with after Adjuvanted vaccines inoculation is arranged, afterwards (the 21st day) frequency is significantly higher for the lymphocytic inoculation of influenza specific C D4 T among the old experimenter.
(d) all similar basically in all groups before the inoculation of influenza specific C D8 T cell with inoculation back GM frequency.
The result- Estimate the HI terminal point
Observational variable:
At the 0th, 21,90 and 180 day: the serum hemagglutination suppressed (HI) antibody titer, to each test separately (resist-H1N1, resist-H3N2 and anti--B antibody) of 3 kinds of strains of influenza viruses that provide in the vaccine.
The intercepting value of the HI antibody of anti-all vaccine antigens is confirmed (equaling 1: 10) by laboratory before analysis.Seronegativity experimenter is the experimenter that its antibody titer is lower than the intercepting value.Seropositivity experimenter is the experimenter of its antibody titer more than or equal to the intercepting value.Being lower than the antibody titer of measuring the intercepting value provides with any value of half intercepting value.
Based on the HI antibody titer, calculate following parameter:
(j) at the geometric mean titer (GMT) of the HI antibody of the 0th day and 21 days, adopt the antilogarithm of logarithm titre conversion meansigma methods to calculate
(k) the seroconversion factor (SF) the 21st day the time is defined as than the increase multiple of the 0th day serum HI GMT the 21st day the time.
(I) serological conversion rate (SC) the 21st day the time is defined as inoculator's percentage rate of HI titre before the inoculation<1: 10 and inoculation back titre >=1: 40, or titre before the inoculation >=1: 10 and inoculation back titre have the minimum inoculator's percentage rate that reaches 4 times of increases.
(m) the serum protective rate (SPR) the 21st day the time is defined as the inoculator's of serum HI titre >=1: 40 percentage rate.
Obtain the 95%CI of the GM of each group respectively.Suppose the number conversion titre and at first to obtain 95%CI number conversion titre meansigma methods with the unknown variance normal distribution.Then through the index conversion of the 95%CI of number conversion titre meansigma methods being obtained the 95%CI of GM.
The serology result of the disappearance that antibody specific detects is not replaced.Therefore, put serum-free in preset time and learn the determination and analysis that result's experimenter does not influence this time point.
The HI result ( Figure 27 and table 49)
GMT is in the same range as in 4 treatment groups before the inoculation of the HI antibody of whole 3 kinds of vaccine strains.After inoculation, the standard Fluarix in the same community, 2 kinds of adjuvants that increase the humoral response among the old people have tangible effect.
GMT is
For AS03+MPL (concentration 2), significantly higher to the GMT of H1N1,
For two kinds of adjuvants, significantly higher to the GMT of H3N2 and B,
Inoculate back 21 days, Fluarix (18-40 year) experimenter replys higher to the HI of New Caledonia and the strain of B/ Jiangsu.
Shown in table 49; In the experimenter more than 60 years old, there are the adjuvant influenza vaccines to exceed European official to the requirement of the lytic virus body influenza vaccines of every year registration [" about being used for the guide explanation that requires of the coordinated flow influenza vaccine that changes of strain of immunological evaluation year " (CPMP/BWP/214/96)].
After inoculation, with regard to the serum protective rate of HI antibody, Fluarix (>=65 years old) group and following group have significant difference:
Flu AS03+MPL (concentration 2) is for the strain of A/ New Caledonia
For each vaccine strain, 2 kinds of serum protective rates that adjuvant influenza vaccines groups arranged are in the same range as than Fluarix (18-40 year) group.
With regard to the positive rate of rotation of HI antibody, Fluarix (>=65 years old) group and following group have significant difference:
Flu AS03+MPL (concentration 2) is for the strain of A/ New Caledonia
Flu AS03+MPL (concentration 1) is for the strain of B/ Jiangsu
For each vaccine strain, 2 kinds of positive rates of rotation that adjuvant influenza vaccines groups arranged are in the same range as than Fluarix (18-40 year) group, except the strain of New Caledonia.
