Abstract

A method for enhancing the immune response to a selected antigen is disclosed. The method entails delivering a particulate adjuvant composition transdermally, preferably using a needleless syringe system. Also described are methods for forming crystalline particles from pharmaceutical compositions and then delivering the same to a subject. The crystallized compositions are particularly suitable for transdermal vaccine delivery using a needleless syringe system.

Description

Transdermal delivery of particulate vaccine compositions
The present invention relates to microparticle compositions.More particularly, the present invention relates to send the method for microparticle compositions, promptly form crystalline particle, then it is delivered to the method for main body by pharmaceutical composition.The suitable especially needleless injector system transdermal administration vaccine that uses of this microparticle compositions.
In non-intestinal delivery technique, deliver drugs in the skin surface and the ability by skin surface (transdermal administration) has many advantages.Particularly, compare with traditional drug-supplying system, transdermal administration safety, convenience and do not have injury, and the danger that infects as acupuncture pain, processed individuality, the pollution that is brought to the healthcare worker by shank and disposable pin once in a while or the danger of infection have been avoided sending together subject matter with non-intestinal.In addition, this blood concentration of sending also institute's administration has given highly control.
Recently, described a kind of novel transdermal administration drug system, it need use needleless injector with control dosage, thereby the microgranule that will contain solid drugs is injected not have and hindered skin and hinder skin by nothing.Particularly, the US5630796 that people such as Bellhouse have has described a kind of needleless injector, and it sends the drug particle that transmits with hypersonic air flow.This needleless injector (also being referred to as " PowderJect needleless injection device ") is used for transdermal administration powdered drug chemical compound and compositions, is used for the gene material being delivered to living cells (for example gene therapy) and being used for biologics is delivered to skin, muscle, blood or lymph.Also needleless injector and surgical knot can be share in to organ surface, solid tumor and/or operation chamber (for example cavity after tumor bed or the tumor resection) delivering drugs and biological preparation.Use this equipment can be safely and easily send and to suit to be roughly the pharmaceutical agent of solid, particulate form preparation.
A concrete needleless injector generally includes an elongated tubular product such nozzle, but it has the rupture disc that the air flue of originally sealing in this nozzle also roughly is placed on this nozzle upstream end place.Be positioned at this rupture disc place and use a launch device to transmit but medicament particle to be transmitted is treated, this launch device with a gas pressure in this diaphragm upstream one side, this air pressure be enough to break this diaphragm and in nozzle, produce hypersonic air flow (containing the medicine particle) to send from its downstream.Therefore the transfer rate of these particles with the 1-8 Mach number can be transmitted from needleless injector, but this transfer rate can easily obtain by the rupture disc that breaks.
The structure of another kind of needleless injector generally includes aforesaid similar elements, it is the drug particle that replacement transmits in hypersonic air flow, the nozzle downstream is equipped with a bistable state diaphragm, this diaphragm can move between static " oppositely " position (wherein diaphragm has a concave surface to contain the medicine particle on downstream face) and movable " turning up " position (wherein the result of the supersonic shock wave effect of diaphragm upstream face makes its downstream face outwards protrude).In this mode, drug particle contained in the diaphragm concave surface is shifted target skin or mucomembranous surface with ultrasonic initial velocity onto from transdermal administration equipment.
Use above-mentioned needleless injector structure that the particle that particle size range is about 0.1-250 μ m is usually carried out transdermal administration.Particle greater than about 250 μ m also can be transmitted by this equipment, and its upper limit is that particle size is brought the injury that things turn out contrary to one's wishes to Skin Cell.The actual range of the particle penetration that is transmitted depends on initial velocity and the skin density and the kinematic viscosity of particle size (for example nominal particle diameter is that the supposition particle is for spherical), particle density, particle impacting skin surface.The target particle density that is used for Needleless injection is generally about 0.1-250g/cm 3, injection speed is generally about 200-3000m/sec.
Unique especially characteristic of needleless injector is the strict control ability of the particle penetration degree of depth that transmits, and makes the target administration arrive diverse location thus.For example, can select particle characteristics and/or equipment operation parameter, thereby for example different intradermal or the length of penetration of subcutaneous transmission are provided.A kind of approach need select particle size, particle density and initial velocity so that about 2-10kg/sec/m to be provided, more preferably from about the momentum density of 4-7kg/sec/m (for example, particle momentum is divided by the particle front face area).Can reach the transmission accurate control, tissue selectivity of drug particle to this control of momentum density.
Said system provides a kind of unique apparatus that is sent to vaccine antigen in skin or the tissue or passes through skin or tissue.But, to render a service in order to increase antigen, many antigens need use immunological adjuvant.Immunological adjuvant plays the immunoreation that increases iuntercellular and body fluid.These adjuvants comprise store adjuvant, absorption and/or precipitation the antigen of giving and be used for keeping antigenic chemical compound here at injection position.The typical case stores adjuvant and comprises aluminium compound and water-in-oil emulsion.
Increase antigenicity although store adjuvant, when subcutaneous or intramuscular injection, often caused serious persistent local response, for example rheumatic granulomas, abscess and cicatrization.Other adjuvant, for example lipopolysaccharide and muramyldipeptide can cause pyrogenic reaction and/or conjunctivo-urethro-synovial syndrome (influenza class symptom, dispersivity joint do not accommodate anterior uveitis, arthritis and urethritis sometimes) by injection.Therefore, need one effectively and the method for safe and continuous transmission adjuvant, thereby improve given antigenic immunoreation.

Contain selected antigen and adjuvant together composition or with the main body adjuvant vaccine combination of administration altogether, when it have than the equivalent antigen that does not give adjuvant larger cause immunoreactive ability the time, demonstrate " the immunogene performance of raising ". Since the stronger immunogenicity of antigen or since in the main body of giving antigen more low dosage or still less the antigen of dosage reach immune response, so vaccine combination can present " the immunogene performance of raising ". The immunogenicity of this raising can be by following mensuration: adjunvant composition and antigen controlling agent are administered into animal body, Application standard is measured relatively antigen titration degree and/or relatively the two iuntercellular immunity, this standard test such as the known radiommunoassay in capable territory, enzyme linked immunosorbent assay (ELISA), CTL mensuration etc. For the purposes of the present invention, " effective dose " of adjuvant should be to improve the altogether amount of administration antigen immune reaction, so that antigen presentation goes out the immunogenicity that improves as mentioned above.
Similarly, " effective dose " of antigen be stimulate immunoreactive amount in the main body to antigen. Immune response can be body fluid, intercellular and/or the protective immune response.
Term used herein " altogether administration " is as when adjuvant and the common administration of vaccine antigen, the meaning is or while or parallel adjuvant and the antigen of transporting, for example when both in same combination, occurs or both in while almost but administration in the composition that diverse location is separating, and adjuvant and antigen are carried at different time in separate compositions. For example, can before or after carrying antigen, identical or different position carry adjunvant composition. Carry adjuvant and carry between the antigen can the interval a few minutes, by several hours, by several days. And, although use Transdermal Delivery such as needleless injector that preparation compositions is administered into skin, can use traditional medicine-feeding technology, as passing through traditional syringe and traditional vaccine rifle administration of vaccines composition.
Term used herein " processing " comprises arbitrarily following: prevention infection or infect again reduces or eliminates symptom, and reduces or eliminate pathogen fully.Processing can play prevention (before the infection) or treatment (after the infection) effect.
" vertebrates main body " meaning is heart-shaped member, particularly mammal of any subphylum, includes, but not limited to human and other primates.The concrete age do not indicated in this term.Therefore, adult and newborn individuality all should be included.
Medicine separately or with other medicines or reagent, is typically made the pharmaceutical composition that can contain one or more additional materials such as carrier, carrier and/or excipient." carrier ", " carrier " and " excipient " typically refer to inertia, nontoxic and not with compositions in other component with harmful interactive material of mode.Can use these materials to increase the amount of solid in the drug particles compositions, for example use those of dispute mist drying or Freeze Drying Technique preparation.The example of used usually " excipient " or " carrier " comprises pharmaceutical grade glucose, sucrose, lactose, trehalose, mannitol, Sorbitol, inositol, glucosan, starch, cellulose, sodium phosphate or calcium, calcium sulfate, citric acid or tartaric acid (with its pharmaceutically acceptable salt), glycine, high molecular weight polyethylene glycol (PEG) and its combination.Illustration excipient with used as stabilizers comprises common obtainable cryoprotector and antioxidant.B. universal method
The invention provides delivery of particulate pharmaceutical composition, particularly vaccine combination.Can use transdermal needleless injector administration device to these microparticle compositions of body delivery.On the existing inoculation method basis that relies on conventional needle and injector to inject technology usually, be improved to the ability of tissue with microgranule (powder) form as skin transdermal administration vaccine combination.Thus, nearly all present vaccine is all by administered intramuscular.But the vaccine of being injected needs the partial draining lymph node, so that the beginning immunoreation.Most of vaccine combination of intramuscular injection will be diffused into surrounding tissue and circulation, therefore loss or diluted very soon.On the contrary, when skin transdermal administration vaccine combination for example, such loss will not take place.This is because the vascularity of upper layers of skin is poor, therefore has the antigenic ability of stronger reservation.Because the course of dissolution of particulate vaccine compositions in skin is slow, so it is retained in the skin better.Cellular component in the skin also can help strengthening the performance of the vaccine of transdermal administration.This is owing to there is the dense network of arborescent cell in the hypodermic layer of langerhans' cells and skin in the epidermal area.These cells are very important to beginning and maintenance immunoreation.By near these immunocytes, carrying vaccine combination, can reach the immunoreation stronger than traditional intramuscular injection.These immunocytes also can be picked up this vaccine and move on to the partial draining lymph node, thus the beginning immunoreation.
Microparticle compositions has also been strengthened the safety and the effect of immunomodulator commonly used such as adjuvant to the transdermal administration of skin or mucosal tissue.Immunomodulator is the important component of vaccine and immunization therapy normally.Immunomodulator has many functions, comprises for example reinforced immunological, inhibition immunity and regulates immunity.The effect of vaccine or immunization therapy has been strengthened in the reinforcement of immunity.The reinforcement of immunity also makes immune system react to more low dose of vaccine combination.For example, aluminum (Alum) adjuvant immunity regulator is used to prepare diphtheria and tetanus toxin vaccine, thereby strengthens their immunogenicity.Some have the immunomodulator that suppresses immune performance and also are used to handle some disease, as auto-immune disease and organ transplantation.Immunomodulator also can instruct immune system generation or Th1-or the reaction of Th2-type, perhaps a kind of reaction conversions of having set up is arrived another kind of.This immunity modulating performance is extremely important to immunotherapy.For example, have the immune main body of being partial to the reaction of Th2-type and be easy to the allergy.The immunomodulator that therefore can help to improve the reaction of Th1-type is used for immunotherapy so that these individual desensitizations.
With regard to the traditional vaccine compositions, typically carry immunomodulator by intramuscular injection.One of problem of this injecting method is that immunomodulator arrives body circulation toxicity afterwards.Reason for this reason, many immunomodulators all can not be used for human body.Because most of injected material is very fast from the injection position diffusion, therefore usually in order to enter circulation effectively, intramuscular injection also needs the immunomodulator (transdermal administration immunomodulator relatively) of high dose.Thus, may need an adjuvant with its activity of generation in injection position or partial draining lymph node, thereby improve immune performance.
According to the present invention, immunomodulator to the transdermal administration of skin or mucosal tissue because of following former thereby favourable.At first, skin and mucosa are the very effective positions of immune system.As mentioned above, the dense network (for example, the arborescent cell of langerhans' cells in the epidermal area and skin layer) that in each layer of skin, has immunocyte.Mucomembranous epithelial cell contains a large amount of Intradermal arborescent cell of going up.These cells are to beginning and keep immunoreation, make their immunity modulation cause target is very important.By carrying immunomodulator in the very near place of these cells, avoid simultaneously because diffusion and disappearing fast, reach than being feasible by the stronger immune modulation effect of intramuscular injection.The effective dose of immunomodulator also can reduce greatly.Help reducing the toxicity relevant than low dosage with many immunomodulators.
Therefore, in one embodiment, the present invention needs a step with traditional pharmacy formation crystalline particle (suitable transdermal administration).Although method of the present invention can be widely used for any pharmaceutical composition, this paper specifically consults and uses liquid state (moisture) or recombinates the method illustration the present invention as raw material of dry vaccine combination.
A kind of conventional method of preparation and storage vaccine medicine relates to freezes in method (lyophilization).Lyophilization relate to one from material dewatered technology, and relate to quick freezing under low-down temperature, then under condition of high vacuum degree by the distillation fast dewatering.This technological model ground produces the low density porous particle with open matrix structure.Be stable on these chemistry of particles, but when it being added in aqueous environment, just recombinate (decompose and/or enter solution) fast.
Other method by sensitivity or preparation of temperature-sensitive biomolecule and storage vaccine combination is a spray drying.Spray drying relates to uses a nozzle, spray webbing dish or miscellaneous equipment with one or more solid solution atomizations, then evaporating solvent from droplet.More particularly, spray drying relates to liquid pharmaceutical (for example solution, serosity, emulsion etc.) with high degree of dispersion and mixes with the hot-air of appropriate volume and evaporate and dry liquid droplet.The normally narrow meshed even spheroidal particle of the feature of spray-dried medicament.These Particle Density are low and dissolution velocity is fast.
In a method of the present invention, fluid composition (moisture or the spray-dried or freeze dried compositions of recombinating) is transformed into suitable drying, the crystalline powder that is conveyed into and/or passes through skin or mucosal tissue.Can be with this fluid composition and appropriate carrier or mixed with excipients with reinforcement crystallization formation, particle structure, rigidity and/or density feature.Preferred carrier or excipient comprise pharmaceutical grade sugar and analog, comprise for example trehalose.Then said composition is carried out drying under suitable evaporation conditions, obtain crystal composition.This crystallization can be shifted out from desiccated surface or container then, for example use mortar and pestle broken gently.The gained crystalline powder can be put into the kit of suitable administration then, thereby use needleless injector that it is administered into main body.
Although in the present invention without limits, above-mentioned method can be used for obtaining size at the about 250 μ m of about 0.1-, and about 250 μ m of preferably about 10-and particle density are the about 25g/cm of about 0.1- 3Crystalline particle.These crystalline particles can be used for handling or the prevention various diseases.
In another embodiment, the present invention relates to delivery of particulate compositions, particularly adjuvant and vaccine combination.As mentioned above, adjuvant and vaccine combination can be crystal form, perhaps can be with amorphous particulate form administration.
The used antigen of the present invention can use produced in several ways well known by persons skilled in the art.Particularly, can use the standard purification technique directly to separate antigen by natural source.Perhaps, can use known technology reorganization ground to produce antigen.Referring to, Sambrook for example, Fritsch﹠Maniatis, Molecular Cloning:ALaboratoryManual, Vols. I, II and III, SecondEdition (1989); DNA Cloning, Vols. I, and II (D.N.Glover ed.1985).Can described aminoacid sequence be that the basis is through the synthetic antigen used herein of the chemical polymerization thing synthetic method of for example solid phase method of peptide synthesis also.These methods are known to those skilled in the art.Referring to, J.M.Stewart and J.D.Young for example, Solid Phase Peptide Synthesis, 2 NdEd., Pierce Chemical Co., Rockferd, IL (1984) and G.Barany andR.B.Merrifield, The Peptides:Analysis, Synthesis, Biology, editors E.Gross and J.Meienhofer, Vol.2, Academic Press, NewYork, (1980), pp.3-254, for solide phase peptide synthesistechniques:and M.Bodansky, Principles of Peptide Synthesis, Spinger-Verlag, Berlin (1984) and E.Gross and J.Meienhofer, Eds., The Peptides:Analysis, Synthesis, Biology, supra, Vol.1, forclassical solution synthesis.
In case after obtaining, interested antigen is formed particulate vaccine compositions as described herein and it is administered into main body, usually with the immunological adjuvants that is used to improve the antigen immune reaction.As explained above, this adjuvant can appear at identical or the independent group compound in, can with vaccine combination administration, perhaps administration before or after the antigen administration simultaneously.In addition, can carry out the adjuvant administration in identical or different position.
Unfortunately, the toxicity height of most of known adjuvants.Therefore, the adjuvant that only suitable at present human body uses is Alum, the aluminum salt composite.
But many adjuvants are used for zooscopy and carry out clinical preceding and clinical research over against several adjuvants that human body uses.
Surprisingly, being considered to human body usually uses the too high adjuvant of toxicity can use this method administration., very unclear by concrete theoretical the constraint, use the transdermal administration method to the percutaneous drug delivery adjuvant, arborescent cell interaction in langerhans' cells and the cortex in the epidermal area of permission skin.These cells are important to beginning and maintenance immunoreation.Therefore, can be by aim at the adjuvant effect that administration obtains raising to these cells or near it.In addition, because the vascularization of upper layers of skin is poor, the amount that enters body circulation adjuvant reduces, and has therefore reduced toxic effect.And because Skin Cell constantly comes off, residual adjuvant is eliminated rather than is adsorbed.And, carry the amount of adjuvant to lack than the amount of using conventional art such as intramuscular injection to carry.Therefore, the present invention can use various adjuvants effectively, and does not have toxicity together.These adjuvants include, but not limited to the adjuvant that formed by for example aluminum salt (Alum) such as aluminium hydroxide, aluminum phosphate, aluminum sulfate; Oil-in-water and water in oil emulsion liquid formulation as Complete FreundsAdjuvant (CFA) and Incomplete Freunds Adjuvant (IFA); By the adjuvant that the bacterial cell wall fraction forms, for example comprise the adjuvant of single phosphinylidyne lipoid A (MPL) (people (1985) Tet.Lett.26:1545-1548 such as Imoto), trehalose dimycolate (TDM) and cell wall skeleton (CMS); Derive from the bacteriotoxic adjuvant of ADP-ribosylation, the potent toxin of lineup's body comprises that diphtheria toxin, diphtherotoxin, pertussis toxin, PT (PT), cholera toxin (CT), escherichia coli heat-labile toxin (LT1 and LT2), false unit cell mattress belong to A type endotoxin, bacillus botulinus C2 and C3 toxin and from the toxin of bacillus perfringens, Clostridium spiroforme and clostridium difficile, particularly ADP-ribosylation bacteriotoxin mutant CRM for example 197, avirulence diphtheria toxin mutation (referring to, people (1992) Vaccine such as people (1989) Adv.Exp.Med.Biol.251:175 such as Bixler and Constantino for example); The Saponin adjuvant of the particle that produces as Quil A (US5057540) or by the Saponin of for example ISCOMs (immunostimulating complex); Cytokine, for example interleukin (as IL-1, IL-2, IL-4, IL-5, IL-6, IL-7, IL-12 etc.), interferon (as IFN-), macrophage clone stimulating factor (M-CSF), tumor necrosis factor (TNF) etc.; Muramyl peptide such as N-acetyl group-muramyl-L-threonyl-D-isoglutamine (thr-MDP), N-acetyl group-non-muramyl-L-alanyl-D-isoglutamine (nor-MDP), N-acetyl group muramyl-L-alanyl-D-isoglutamine base-L-alanine-2-(1 '-2 '-two palmityls-sn-glycerol-3 hydroxyl phosphorus acyloxy)-ethamine (MTP-PE) etc.; Derive from CpG family molecule, CpG dinucleotide and comprise the synthesis of oligonucleotides nucleotide of CpG composition adjuvant (referring to, people J.Immunol. (1998) 160:870-876 such as people Vature (1995) 374:546 such as Krieg and Davis for example), for example TCCATGACGTTCCTGATGCT (SEQ ID NO:1) and ATCGACTCTCGAGCGTTCTC (SEQ ID NO:2); And synthetic adjuvant, as PCPP people Vaccines (1998) 16:92-98 such as (poly-[two (carboxyl phenoxy groups) are phosphazine] () Payne.These adjuvants can be from many suppliers such as Accurate Chemicals, RibiImmunechemicals, Hamilton, MT, GIBCO, Sigma, and St.Louis, MO is commercially available.
In case after obtaining, will have or not have antigenic adjuvant interested to use any suitable granulating technique to form the particle of suitable transdermal administration, these technology for example have air-dry (crystallization), lyophilization (lyophilizing), spray drying or supercritical fluid technology.As mentioned above, also said composition can be made crystal composition.
After their form, use suitable transdermal administration technology with this particle transdermal administration to mammalian tissues.The various particle acceleration equipments of suitable transdermal administration substances of interest are known in the art, and can find use in enforcement of the present invention.The particle that particularly preferred transdermal drug delivery system uses needleless injector will contain solid-state drug is transmitted in intact skin and the tissue with control dosage or passes through wherein.Referring to, people's such as Bellhouse US5630796 for example, it has been described a kind of needleless injector and (also has been referred to as " PowderJect _Needleless injection device ").Other needleless injector structure is known in the art and description is arranged in this article.
To prepare the mode that is complementary particle is administered in the main body, and its amount is for reaching the effective dose of required physiological reaction with dosage.This reaction that produces should have the effect of preventing and/or treating.Therefore, for example, if just carrying antigen or vaccine combination, conveying capacity should enough produce immunoreation.If adjuvant and antigen are carried altogether, its conveying capacity should be enough to improve the antigenic immunoreation of common conveying so.Obviously, the amount for the treatment of administration composition depends on the concrete material carried, pending main body and waits the disease of preventing or handling.
Usually, the adjuvant of about 0.5 μ g-1000 μ g, more preferably the about 500 μ g of 1 μ g-adjuvant and most preferably from about the adjuvant of the about 300 μ g of 5 μ g-be effective to improving the antigenic immunoreation of giving.Therefore, for example, for CpG, the employed dosage range of this method is about 0.5-50 μ g, more preferably about 25 μ g of 1-and about 20 μ g of 5-most preferably.Similarly, concerning Alum or PCPP, the employed dosage of this paper is the about 500 μ g of about 25 μ g-, preferably about 250 μ g of about 50-and about 150 μ g of 75-most preferably from about.Concerning MPL, the employed dosage range of this method is about 10-250 μ g, preferably about 20-150 μ g and about 75 μ g of 40-most preferably from about.
Those skilled in the art use conventional method just can easily measure the dosage of other adjuvant.Dosage depends on and comprises common administration antigen, and this adjuvant is as many factors of the ability of immunostimulant.
Similarly, if transdermal with identical or different composition forms administration antigen, usually with 50ng-1mg and more preferably the about 50 μ g antigens of 1 μ g-be used to produce immunoreation.Required accurate amount is according to age of pending main body and conventional health status, treatment conditions and specific antigen or selected antigenic severity, administration position, and other factors and changing.Those skilled in the art can be by reading this description and easily measuring suitable effective dose by routine test.
It can be unit dose or multiple dose that dosage is handled.For vaccine combination, multiple dose is a kind of: the vaccinated phase I can be individual individually dosed for 1-10, then give other dosage at following interval, select to keep and/or the reinforced immunological reaction, for example second dosage was at 1-4 month, if necessary, after some months, give later dosage.Dosage mechanism also to small part, is determined and is relied on doctor's judgement by the needs of main body.And, if wish prophylactic words, before infecting for the first time, give said composition usually with interested pathogen.If wish treatment, for example reduce symptom or recurrence, after infecting for the first time, give said composition usually.C. test

Particulate vaccine compositions
Carrying out following research is in order to evaluate different excipient and prilling process the physical property of gained particulate vaccine compositions to be made the influence of vaccine immunogenicity again with these.Subunit protein antigen of select diphtheria toxin, diphtherotoxin (dT), purifying and the different excipient preparations that comprise mannitol (adding polyvinylpyrrolidone (PVP)), sucrose and trehalose.Also comprise two kinds of powder-making techniques, lyophilization and air-dry (evaporation drying).In order to test every kind of goods, using 3 " stainless steel sift of diameter partly classifies the gained microparticle compositions by following particle:<20 μ m, 20-38 μ m, 38-53 μ m and 53-75 μ m.
The physical characteristic of particulate vaccine compositions comprises the evaluation to size distribution, osmotic energy, light microscopy, scanning electronic microscope examination, absolute density, pore size distribution, surface area analysis and X-ray powder diffraction.
In order to measure with needleless injection device (PowderJect for example _Needleless injection device) carries or the immunogenicity of making vaccine again by conventional syringe/pin injection, 0 and 4 weeks inoculation Balb/C mouse (female, 6-8 age in week).Use PowderJect _The mouse of needleless injection device inoculation accepts to be equipped with 5 μ g vaccines of 1mg excipient.With conventional needle and syringe peritoneal injection contrast mouse.Strengthen two weeks in the past after, from 8 mouse, collect serum and compile, measure dT antibody by ELISA.
The result of the physical characteristic of microparticle compositions is as follows: (1) air-dry method produces the high density crystalline particle, and produces the noncrystalline powder of low relatively density during lyophilization; (2) the particle size distribution demonstration does not rely on excipient and used granulation process.These particles through screening be divided into 5 classes (<20 μ m, 20-38 μ m, 38-53 μ m, 53-75 μ m and>75 μ m), and the Mass Distribution of each part is about equally.
The result of immunogenicity evaluation be described in following table 1 and 2 and Fig. 1 in.This shows the immunogenicity between the different particulate vaccine compositions closely similar (between the different big fraction of all goods and same article).All microparticle compositions by the needleless injector administration cause than the higher antigen titration degree of matched group (conventional needle and syringe administration).The trehalose excipient demonstrates better slightly than other goods, and 20-53 μ m partly demonstrates higher immunogenicity (referring to Fig. 1).But<20 μ m and>75 μ m particles part are all compared according to the immunogenicity of (Aquo-composition, conventional needle and syringe administration) and are wanted high.Also can find out the Needleless injection (PowderJect of crystallization vaccine combination particle _) administration generation comparison photograph (conventional needle and syringe) seroconversion rate (referring to table 2) that injecting method is high.Thus, at single PowderJect _The animal of 97% (having 157 in 162) produces serum antibody after the inoculation, yet the seroconversion rate of matched group is 37.5% (having 3 in 8).
