S. application series number 12/848,856 and international application no PCT/US2010/54755, and its content is incorporated into by reference.
Technical field
The present invention relates to therapy, described therapy comprises that using interferon-' alpha ' treats pathological conditions (for example hepatitis b virus infected).Particularly, the present invention relates to method and system, its mode with body internal interference element-alpha levels of control patient is used interferon-' alpha ', so that the result of optimizing therapeutic regimen.
Background technology
It is a great public health challenge that hepatitis B virus (HBV) infects, and according to estimates, only in the U.S. 730,000 chronically infected adults is just arranged, and annual financial burden is 1,300,000,000 dollars.Present available treatment selects to comprise parenteral medicament and medicinal preparation for oral administration that described pharmacy effect is in different hosts and viral target.These comprise: the medicament of the receptor of targeting on host cell membrane such as the interferon of standard and peg-IFN (peg-interferon), and suppress nucleotide and the nucleoside analog of the dependent archaeal dna polymerase of HBV RNA.
HBV virus is propagated by following manner: blood and blood products, and intravenous drug misuser's syringe needle pollutes, spreads through sex intercourse, and the vertical transmission from infected or carrier parent to the baby.In the world, this disease is most commonly in the some areas in Southeast Asia, Africa and South America.In these areas, cause a high proportion of infected individual to become the chronic carrier of hepatitis B to the baby's at early stage age vertical transmission meeting.HBV can cause acute severe hepatitis, i.e. a kind of fast progressive, frequent cause death disease of form, and wherein a large amount of parts of liver are destroyed.As the result that chronic hepatitis B infects, the male baby who obtains hepatitis B has about 40% chance and dies from liver cirrhosis or primary hepatoma.Infected women has about 15% chance and dies from the similar death that chronic hepatitis B infects at birth.Although the patient usually can be from the acute hepatitis rehabilitation, in some patient, high-caliber virus antigen continues period or the uncertain period of prolongation in blood, cause chronic infection.Chronic infection can cause chronic persistent hepatitis.Chronic persistent hepatitis can cause fatigue, liver cirrhosis and hepatocarcinoma (a kind of primary hepatocarcinoma).The mechanism that HBV brings out cancer is unknown, although according to supposition, it may directly trigger tumor development, or indirectly triggers tumor development by chronic inflammatory disease, liver cirrhosis and the cell regeneration relevant with infection.
Because current clinical practice only causes the removing of HBV in a part of infected individual, thirst for very much new therapy.In addition, the time period that current therapeutic scheme continue to prolong, and the patient often suffers the side effect of many disadvantageous dose dependents, comprises serious influenza sample symptom, and described symptom can adversely affect patient's compliance and result.Therefore, need the method that is used for the treatment of viral infection such as hepatitis B of improvement, in particular for the exploitation of the method and system of using interferon-' alpha ', described replying with the mode of therapeutic outcome for the treatment of of using to optimize comprising this medicament carried out.
Summary of the invention
Disclosure provided herein comprises the result who obtains from clinical trial, and described clinical trial is used for the combined interferon-' alpha ' of research and ribavirin in the patient's of experience chronic hepatitis C treatment continuous subcutaneous administration.The clinical data that obtains from this test shows that the continuous subcutaneous administration of interferon-' alpha ' can be higher than the time period that critical effectiveness threshold value prolongs for the bulk concentration of keeping interferon-' alpha ', and this can promote the virus sweep among the host.
Although the infectious agent with the interferon-' alpha ' treatment in the clinical trial that is discussed below is hepatitis C virus, the method relevant with lasting interferon-' alpha ' level and data go in some other treatment background.Particularly, interferon-' alpha ' has effective antiviral activity, but can directly not act on virus or copy complex.On the contrary, interferon-' alpha ' works by the gene (ISG) of inducing IFN to stimulate, this can in cell, set up non-viral specific antiviral state (referring to, such as people such as Bekisz, Growth Factors 22,243-251 (2004) and Sen, Annu.Microbiol.55,255-281 (2001).Microarray analysis shows that hundreds of genes can be induced by disturbed element-α, and are many relevant with antiviral activity, replys but other gene participates in lipid metabolism, apoptosis, protein degradation and inflammatory cell.In addition, interferon-' alpha ' can promote memory T-cell proliferation, prevention T-apoptosis and stimulate natural killer cell activation and dendritic cell maturation.Under this background, if use (for example via the continuous infusion pump) in the mode that causes this lasting cytokine levels, it is believed that the interferon-' alpha ' that use in so outer seedbed can prevent immunodepletion, and strengthen the adaptive immune response for hepatitis B virus.

Exemplary aspect of the present invention and embodiment
Present disclosure comprises the result from clinical trial, the new therapeutic scheme of described clinical experimental study, and described new therapeutic scheme comprises: in the patient of experience chronic hepatitis C treatment, the interferon-' alpha ' that continuous subcutaneous administration and ribavirin are combined.The clinical data that obtains from this test shows that the continuous subcutaneous administration of interferon-' alpha ' can be higher than the time period that critical effectiveness threshold value prolongs for the bulk concentration of keeping this therapeutic agent.This clinical data further shows, eliminates hepatitis C virus among the patient that these therapeutic schemes can the conventional antiviral therapy of former confirmation be difficult to treat.As a result, that therapeutic scheme disclosed herein has solved is long-standing, but not have the needs of solution, particularly optimize the needs of the administration of interferon-' alpha ' in the mode that overcomes the problem relevant with the conventional therapy scheme.Those skilled in the art are apparent, can make different combinations and/or modification and variation in such therapeutic scheme, and this depends on the different physiological parameter of observing in the patient.For example, make an explanation or the feature described can be used for another embodiment as the part of an embodiment, to produce other embodiment.
Although the infectious agent with the interferon-' alpha ' treatment in the clinical trial that is discussed below is hepatitis C virus, the method relevant with lasting interferon-' alpha ' level and data go in some other treatment background.Particularly, interferon-' alpha ' has effective antiviral activity, but can directly not act on virus or copy complex.On the contrary, interferon-' alpha ' works by the gene (ISG) of inducing IFN to stimulate, and this can set up non-viral specific antiviral state in the patient.For example, observing interferon-' alpha ' usually can promote memory T-cell proliferation, prevention T-apoptosis and stimulate natural killer cell activation and dendritic cell maturation.
HBsAg removes and seroconversion (by characterizing in the loss that is with or without anti--HBs antibody and forms lower serum HBsAg) be to the outstanding feature thing of the successful immunological response of HBV infection and to clinical cure near the result.The HBsAg removing is defined as, and HBsAg disappears from serum.The HBsAg seroconversion is defined as, and HBsAg disappears and anti--HBs antibody occurs.When the removing of considering to be used for the treatment of the different therapeutic agents that HBV infects and seroconversion are renderd a service, the research indication, therapy based on interferon, peg-IFN α (peg interferon a particularly, PEGIFNa), realize that HBsAg removes and seroconversion aspect obviously be better than the nucleoside/nucleotide analog (referring to, such as people such as Lau, N Engl J Med 2005,352:2682-2695; The people such as Marcellin, N EnglJ Med 2004,351:1206-1217; The people such as Marcellin, Gastroenterology 2009,136:2169-2179; The people such as Chan, Ann Intern Med 2005,142:240-250; The people such as Chan .Hepatology 2005,41:1357-1364; With the people such as Tian, Zhonghua Gan Zang Bing Za Zhi 2006,14:806-810.The nucleoside/nucleotide analog also shows other shortcoming, the course for the treatment of that comprises the development of resistance and do not have to establish.
In some research on the impact of interferon-' alpha ' in the individuality that HBV infects, notice, HBsAg clearance rate in the patient who accepts the PEG-IFNa monotherapy is significantly higher than those patients that accept conventional IFNa monotherapy, namely may be because their different pharmacokinetics and pharmacodynamics distribute the phenomenon cause (referring to, such as people BMC Infectious Diseases2011 such as Li, 11:165; The people Zhonghua Gan Zang Bing Za Zhi 2006 such as Tian, 14:806-810; The people Chinese J Exp Clin Virol 2006 such as Cui, 20:331-333; The people Journal of Medical Forum 2010 such as Li, 31:51-53; With people Clinical Medical Journal of China 2006,13 such as Guan; 959).In these researchs, use conventional (not Pegylation) IFNa the next day of per once, it reaches rapidly peak concentration in blood, and the compartment of terrain reduces.Use weekly PEG-IFNa once, its effective haemoconcentration continue a week (referring to such as people such as Lau, Liver International 2009,29:125-129).At present, about the up-to-date treatment guide prompting of the management of CHB, should use PEG-IFNa and substitute conventional IFNa, to improve antiviral response.
As disclosed herein, if regulate the administration of interferon-' alpha ' (for example not peg-IFN) in the mode (for example by the continuous infusion pump) that in the patient, produces this lasting cytokine levels, it is believed that, the interferon-' alpha ' that use in outer seedbed like this can promote it preventing immunodepletion and strengthening for the effect in the adaptive immune response of hepatitis B virus, thereby causes larger removing and seroconversion speed.
Embodiment of the present invention comprise: continuous subcutaneous administration interferon-' alpha ' is being higher than the critical lasting time period of effectiveness threshold value in the body in order to keep this therapeutic agent by the bulk concentration among the hepatitis b virus infected patient.For example, exemplary embodiment of the present invention comprises: continuous subcutaneous administration interferon-' alpha ' is higher than at least at least 1 week at least 48 weeks of 100-700pg/mL (for example 300pg/mL) in order to keep the bulk concentration of this therapeutic agent.In typical embodiments of the present invention, the embodiment of the not Pegylation of interferon-' alpha ' concentration (for example 100-700pg/mL) expression interferon-' alpha ' 2a or interferon-' alpha ' 2b (is for example produced by Schering Corporation

)/sky continued at least 1 week at least 48 weeks, for example as discussing in detail among the embodiment 2 below.Another exemplary scheme comprises: continuous administration IFN-α 80 continued at least 1 week at least 48 weeks in 000IU/kg/ days.Another exemplary scheme comprises: continuous administration IFN-α 120 continued at least 1 week at least 48 weeks in 000IU/kg/ days.Another exemplary scheme comprises: continuous administration IFN-α 160 continued at least 1 week at least 48 weeks in 000IU/kg/ days.Another exemplary scheme comprises: use weekly continuously hypodermically happy can the continuing at least 1 week to arrive at least 48 weeks by 1.5 μ g/kg of wearing.Usually, in such scheme, the patient also receives oral nucleoside analog, such as lamivudine, adefovir dipivoxil, Entecavir, Sebivo or tenofovir two pyrrole furan esters.
Finished the patient after first therapeutic scheme of very first time section (such as 1,2,3,4,5,6 or 7 day, 1,2,3 or 4 weeks etc.), can analyze, to observe for example serum interferon-alpha levels and safety/tolerance data and outcome measure, such as exemplary measuring disclosed herein.Such as what discuss among the embodiment 3 below, then can design based on this analysis result the therapeutic scheme of patient-specific.For example, suppose that described analysis shows that the cyclical level of interferon-' alpha ' is in the target scope, the patient can continue the treatment of appointment in the remaining time of the course for the treatment of.Perhaps, can use the therapeutic scheme of patient-specific to the patient, described therapeutic scheme is designed to for example compare increase serum interferon-alpha levels with first therapeutic scheme that is administered to described patient.
Embodiment of the present invention comprise system in addition, and such as comprising those of computer processor etc., described processor etc. are attached to the medicament infusion pump, and are fit to send interferon-' alpha ' according to particular treatment.In some embodiment of the present invention, described system comprises one or more controlling organizations, and described controlling organization is designed to regulate sending of interferon-' alpha ', for example allows to distribute to send it those according to predetermined infusion.For example, in some embodiment of the present invention, processor control therapeutic scheme, described therapeutic scheme comprises the infusion distribution that is designed to consider following factor: one or more features of patient (for example body weight), and/or one or more features of the hepatitis virus of infected patient (for example genotype), and/or be administered to one or more features (for example it and polyalkylene glycol moiety puts together) of patient's therapeutic agent.Randomly, such distribution is selected from a plurality of predetermined infusions distributions.In certain embodiments of the invention, described system can operationally be attached to input, described input provides the information (for example being attached to the input of sensor) about the exogenous IFN-α concentration among the patients serum, then regulate the dosage of the interferon-' alpha ' that is administered to the patient with described processor, thereby regulate serum-concentration in the body that obtains up or down (thereby for example falling in the predetermined target level scope).
Embodiment 2: give the subcutaneous company of patient that can not make to the conventional therapy scheme HCV infection of replying The clinical research of continuous infusion interferon-' alpha '
Background and principle
The treatment of chronic hepatitis C has shown inhomogeneous success, and current clinical practice has only been eliminated HCV in about 50% infected individual.As a result, exist one group of remaining factor such as virogene type, they can for example be reduced in the response rate in the genotype 1.Use Polyethylene Glycol interferon-' alpha ' and ribavirin to HCV genotype 1 patient's optimal treatment, caused between 41-60% virological response (SVR) rate that continues (referring to, such as people Lancet2001 such as Manns; 358:958-965; The people N Engl J Med 2002 such as Fried; 347:975-982; The people Ann Intern Med 2004 such as Hadziyannis; 140:346-355; With people C.JHepatol 2005 such as Zeuzem; 43:250-257).These results' improvement and former nonresponder's again treatment is considered to the ultimate challenge of this area.
By keeping constant blood levels, the Pegylation of interferon (IFN) α has improved the pharmacokinetic profiles of conventional interferon-' alpha '.This has realized weekly 1 time IFN-α administration, and produces higher response rate.But, verified and since the IFN-α volume of distribution that causes of Pegylation be subject to remarkable restriction (referring to, such as people Semin Liver Dis 2003 such as Zeuzem; 23 supplementary issue 1:23-8), namely a reduction biological activity also reduces the factor that treatment is renderd a service potentially.As disclosed herein, the continuous administration by puting together the IFN-α that carries out chemical modification with polyhydric alcohol not, full effect IFN-α albumen that can be by lasting and constant level is provided (having the albumen with the pharmacokinetic profiles of endogenous interferon equivalence) overcomes these problems.
In chronic hcv patients, studied continuous IFN-α infusion aspect.For example, the people such as Carreno in 28 days patient of 12 continuous subcutaneous IFN-α 2a of usefulness (9MIU) treatment, observe Serum ALT remarkable reduction (referring to, such as people J Med Virol1992 such as Carreno; 37:215-219).Do not observe the irreversible side effect that needs dosage to revise.In the research from people such as Schenker, among the patient with the IFN-α 2b course of therapy of standard before 7, with 60, the speed of 000IU/h (1,000 ten thousand IU/ week), by continuous h inf use IFN-α 2b continue 3 months period (referring to, such as people J Interferon Cytokine Res1997 such as Schenker; 17:665-670).At the infusion site place, continuous infusion is well tolerated.In addition, compared with former intermittent administration, the type of systemic side effects is similarly, but intensity is lower.
With regard to h inf, Medtronic Inc. have a kind of pump delivery system (
Figure BDA00001901483400531
The little infusion pump of 508 types), this system the every day in 10 chronic hcv nonresponders 9 μ gIFN α con-1 continuous administration in show good safety and toleration characteristic (referring to, such as people Hepatology 2003 such as Tong; 38:304A).Preliminary data from the people's such as Tong research shows, compares with other therapeutic alliance, and at similar time point place, HCV RNA significantly reduces.In addition, the IFN-α of high dose and PEG-IFN-α produced among the former nonresponder result that improves (referring to, such as people J Viral Hepat 2003 such as Vrolijk; 10:205-209; The people Hepatology 200542:657A such as Marcellin; With people J Hepatol2006 such as Cornberg; 44:291-301).Although in these researchs, see more continually side effect, do not think that toleration significantly is lower than standard care.
Nearest test confirms, when realizing SVR, best RBV dosage (approximately 15mg/kg/ days) important as the IFN-α dosage of the best (referring to, such as people J Hepatol2004 such as Reddy; 40:149; With people Hepatology 2005 such as Shiffman; 42:217A).Observe in nearest research significantly that higher SVR leads, the RBV administration that described investigation and comparison is fixing and based on the administration of body weight (referring to, such as people Hepatology 2005 such as Jacobson; 42:77A).Nonresponder's moderate proportions is associated with relatively poor patient's compliance, may be subjected to the impact of following factor: neuropsychiatric ill effect, the doctor who regulates or stop medicament based on cytopenia.Reduce if prevented the dosage that is caused by adverse events or laboratory abnormalities, SVR leads may be higher.
This embodiment provides the data from clinical trial, and described clinical trial design becomes to check that the continuous administration of IFN-α is on the patient's of verified (PEG-) IFN-α/RBV therapeutic alliance refractory impact.For the patients with chronic hepatitis C of former (PEG-) IFN-α/RBV therapeutic alliance refractory, we have studied and 15mg/kg/ days RBV

Combined high dose IFN-α 2b (Intron
Figure BDA00001901483400541
) continuous 48 weeks of subcutaneous administration and best side effect control, in order to keep IFN-α 2b and 48 weeks of RBV of the highest possibility dosage.As discussed below, we observe with weekly 3 times or every day 1 subcutaneous injection IFN-α 2b compare, continuous subcutaneous pump is sent the toleration of the raising of IFN-α 2b, and because antiviral activity and the biological value of the increase that the lasting and higher level of full effect interferon-alpha proteins causes.
The aspect of this clinical experimental study is disclosed below.

Adverse events
Interferon Alpha-2b
The ill effect that runs at most generally includes: headache, tired, generate heat/shiver and myalgia.These seriousness is normally light, and observes tachyphylaxis in therapeutic process.Important side effect comprises neuropsychiatric symptom, such as drowsiness, depression and emotional lability.Based on the WHO/NCI standard, the seriousness of most of significant changes of hematology's value (Hb, WBC, neutrophil cell and platelet) is slight or medium (grade 1 or 2).
Other side effect comprises bringing out of anorexia, the erythema at the place, injection site, diarrhoea and autoimmune disease (particularly thyroiditis).
Ribavirin
The side effect of frequent report is: feel sick, anorexia, dyspepsia, dizziness, rash, pruritus, macule, cough, nasal congestion, dyspnea.In the former research, the most seriousness in these events is slight to medium.The main toxicity of ribavirin is hemolytic anemia, and this observes in the patient of PEG-IFN-α/ribavirin therapy of about 13%.Reported the fatal and nonfatal myocardial infarction in the patient with anemia that ribavirin causes.
Dosage is regulated or is interrupted
Usually reduce to realize the control of common adverse events by dosage; But, in development, the gestation of life-threatening adverse events, cardiopathic discriminating or heart dysfunction or do not meet in the situation of requirement of birth control practice, must for good and all interrupt IFN-α 2b and RBV therapy.
The medicament of coexistence
In therapeutic process, can use acetaminophen the side effect of IFN-α 2b is minimized.Total daily dose of acetaminophen should be no more than 4 grams.In the situation of anemia, can use erythropoietin, and allow blood transfusion.If depression or depressed symptom occur, allow to use optionally serotonin reuptake inhibitor (SSRI).Except the medicine or therapy in culling level, mentioned, in research process, allow the medicament of coexistence, as long as this is expected not impact of result of study.The use of the medicament of coexistence must be recorded in CRF (statement type, dosage and persistent period).If possible, the medicament of existing coexistence should not change in research process.

1. the preliminary analysis of clinical testing data
A. background:
Compare with the IFN-α of standard, the Pegylation of known IFN-α can improve the PK with higher SVR and distribute.But volume of distribution and biological activity significantly reduce.Under this background, confirm from the preliminary clinical data of clinical trial, not only can stop the crest relevant with adverse events to the continuous exposure of therapeutic IFN-alpha level, and can stop with inferior therapeutic drug levels and virus and break through relevant trough.
B. method:
Combined with the RBV (1000-1600mg/ days) based on body weight, use the infusion device (Medtronic MiniMed 508) that is used for infusion of insulin, by continuous subcutaneous administration, 30 HCV genotype 1 (n=24) and 4 (n=6) patient accept 6,9 or 12MIU IFN α-2b (n=10/ group) every day.Then assess safety, toleration, dynamics of virus and pharmacokinetics.Has the previous history that treatment unresponsiveness (n=20), recurrence (n=7) or virus is broken through (n=3) during the former PegIFN-α of the patient who in this research, comprises/RBV treatment.N=13 position patient has liver cirrhosis when the treatment beginning.Permission records the HCVRNA feminine gender in the 24th when week by TaqMan HCV check, and (patient of LLD<15IU/mL) finishes the treatment of 48 weeks.
C. PRELIMINARY RESULTS:
In the 4th when week, use respectively 6,9 and 12MIU IFN-α/sky, observe 1.19 (95%C10.55-1.83), 1.21 (95%CI 0.38-2.04) and 2.67 (95%CI 2.38-2.97) log 10The average HCV RNA decay of IU/mL (12MIU with respect to 9MIU/6MIU, p<0.0001).IFN-alpha levels dose dependent ground increases, and reaches peak level between 48 hours and the 1st week, succeeded by steady-state level.Between 48 and 96 hours, the 1-(2-amino-4-hydroxy-6-pteridinyl)-1,2,3-propanetriol level similarly increases in 3 groups, has higher a little steady-state level in the 12MIU group.6,9 and 12MIU IFN-α/sky, the HCV RNA that was implemented in for the 24th week in 2 (20%), 5 (50%) and 5 (50%) patients is negative respectively.The AE major part is slight to medium, normally IFN-α-relevant.6 SAE of 5 patient experiences, comprise: at the community acquired pneumonia in the 10th week, diarrhoea, dehydration and heating in the 12nd week, upper respiratory tract infection in the 6th week, injection site reaction in the 18th week, the epilepsy (all 12MIU) that brings out in the hyperglycemia in the 21st week subsequently, and at the injection site reaction (9MIU) in the 12nd week.SAE can cause 3 patients' treatment time-out and 3 patients' permanent interruption; 4 in them have liver cirrhosis.Do not observe with patient's pump and handle relevant problem.
D. preliminary analysis:
9 and 12MIU/ days dosage, the continuous subcutaneous administration of IFN-α in the patient who is difficult to treat shows the high the 24th all response rates.Compare with lower dosage, every day, 12MIU IFN-α showed obvious stronger HCV RNA decline when the 4th week.Found that good safety and toleration distribute.Be appreciated that the relevant adverse events of typical interferon in the maximum dose level group in 12MIU IFN-α/sky and in liver cirrhosis patient, seem more remarkable.
2. the sign of the aspect of preliminary clinical testing data
Some important parameters when present disclosure has been established by continuous h inf with interferon-' alpha ' treatment hepatitis.
The SCIN-C test that (Erasmus Medical Center) carries out in the Erasmus medical center in the Rotterdam, NED city is 3 groups (therapeutic scheme) research, has 10 experimenters in each group/scheme.Interferon-' alpha ' dosage in the test is to use 6MIU, 9MIU and 12MIU by pump every day, uses concomitantly the oral ribavirin based on body weight.Patient under study for action is former treatment loser, and all is genotype 1 or 4.Treatment in the past and the specific data of some experimenter are shown in following table 2.
Table 2-SCIN-C number of subjects certificate
Figure BDA00001901483400641
Figure BDA00001901483400651
Based on the data from this table, we have following summary statistics:
Genotype 124/30 (80%), the 12nd all interferon-' alpha ' nonresponder the 10/30 (33%), the 24th all HCV positives 12/30 (40%), recurrence/bounce-back 8/30 (26.7%).Verified in clinical practice, be difficult to most again treat the 12nd all nonresponders, and recidivist and bounce-back person's treatment difficulty is minimum.
In research process, the blood levels of measurements interference element-α, the patient's who is produced by the therapeutic scheme that uses in this test pharmacokinetics and pharmacodynamics information (such as average interference element-α and neopterin concentrations) for example are presented among Fig. 1.Be presented at the data acknowledgement among Fig. 1, have the strong dose response to the interferon-' alpha ' of using according to disclosed therapeutic scheme.The data that are presented among Fig. 1 further confirm, send the interferon-' alpha ' of higher concentration according to the therapeutic scheme that uses in this test, can cause the interferon-' alpha ' of the correspondingly higher concentration that continues in vivo.
Fig. 2 has shown the viral attenuation curve in the patient of interferon-' alpha ' resistance seriously (so and these patients be difficult to treatment).As shown in Figure 2, in 6MIU/ days treatment groups, there are 5 experimenters to show significant resistance.In these 5 experimenters, only patient 8 shows sane replying in the 8th week, subsequently bounce-back.In the former treatment, all these 5 experimenters treated unsuccessfully in the 12nd week or the 24th week.5 experimenters with more sane HCV decay in Fig. 3, have been shown.
The data that Fig. 3 provides show steadily and surely replying in the 6MIU treatment group.In the lowest dose level treatment group, recording patient 2 and 3 by the quantitative RNA test in the 24th when week is that virus is negative, but is measured as the positive by the qualitative high sensitivity test when the 24th week, and withdraws from research.Other experimenter proceeds research.
In 9MIU/ days groups, there is the experimenter of 4 interferon-' alpha ' resistances.This data show is in Fig. 4 A.More interested is that 6 bit tables in 10 experimenters of 9MIU/ days groups reveal steadily and surely replys.Data show is in Fig. 4 B.In these experimenters of 9MIU/ days groups, be the interferon-' alpha ' resistance in the former PEG treatment all.
In 12MIU/ days treatment groups, there is not the experimenter of interferon-' alpha ' resistance.3 experimenters withdraw from, but 9 have shown quite sane replying up to now, as shown in Figure 5.The dynamics of virus summary data is shown in following table 3-5.

3. the discussion of data:
EVR (EVR) is defined as, and in the patient with low initial virus load, virus load is reduced by at least 2log or virus feminine gender before the 12nd week.The EVR also clinical success with final is relevant consumingly, but does not resemble the RVR strong.In SCIN-C test, 4 (50%) among 8 patients with the viral data that record realized EVR at 6MIU/ days in the treatment group, and 3 (50%) among 6 patients with the viral data that record realized EVR at 9MIU/ days in the treatment group.In maximum dose level group (12MIU/ days), all 6 experimenters' (100%) that arrived for 12 weeks show EVR.
Virus negative (VN) is the continuous demands of SCIN-C scheme when the 24th week.Not that the negative patient of virus is interrupted in this research when the 24th week.In 6MIU/ days treatment groups, 1 (12.5%) among 8 experimenters with 24 weekly datas is that virus is negative, and 2 experimenters still are in the treatment.At the middle dosage of 9MIU/ml, 2 (25%) among 8 experimenters with 24 all measurement results are that virus is negative, and 3 experimenters are still in treatment.In 12MIU/ days treatment groups, 2 experimenters have reached VN when the 24th week, and 2 experimenters are virus-positives when the 24th week, and 3 experimenters are retained in the treatment.
Viral attenuation data when 4 time-of-week point as shown in Figure 6.Shown in the curve among this figure, when 4 week, between dosage, there is significant difference.This is more clearly shown by Fig. 7, the figure illustrates the virus decay (all patients) that realizes by administration.
Data provided herein show, with oral ribavirin based on weight, using insulin pump is safe and effective by h inf continuous administration interferon-' alpha ', and confirm first, by the blood levels of control interferon-' alpha ', we can obtain the dynamics of virus of dose dependent.Although this data acknowledgement the effectiveness of disclosed method in the patient of experience chronic hepatitis C treatment, it will be understood by those skilled in the art that, these methods can be used for originally patient for the treatment of hepatitis c, also consider the importance of for example carrying out the scheme of observing, with produce higher treatment success rate (rather than, for example, adopt the conventional therapy scheme of observing, to have higher mortality).
II. the additional analysis of clinical testing data
As noted above, for clinical trial, with 1: 1: 1 ratio randomization, use insulin pump to accept 6,9 or 12MIU IFN α-2b (Medtronic MiniMed 508) totally 48 weeks every day by continuous subcutaneous administration 30 HCV genotype 1 (n=24) and 4 (n=6) patients.All patients in test accept the ribavirin (1000-1600mg) based on body weight.Having analyzed the blood serum designated object (1-(2-amino-4-hydroxy-6-pteridinyl)-1,2,3-propanetriol, 2,5-oligoadenylate synthetase OAS], B2M) of HCVRNA level, serum I FN-alpha levels, immune activation, external T cell proliferation and IFN-γ generates.T=0,4,8,12,24,48,72,96 hours, the 1st, 2,3,4 and 24 weeks after treatment, collect blood sample.Use clinical trial, assessment safety and toleration, and study former dynamics of virus (nonreply: n=20 for the treatment of among the failed patient; Recurrence: n=7; Or virus breaks through: n=3).6,9 and 12MIU group in, liver cirrhosis is present in respectively among 3,3 and 7 patients.
Virological response is shown in following table 6.In the 4th week, 6,9 and 12MIU IFN-α/sky, observe 1.19 (95%C10.55-1.83), 1.21 (95%CI 0.38-2.04) and 2.67 (95%CI2.38-2.97) log respectively 10The average HCV RNA decay of IU/ml (12MIU with respect to 9MIU/6MIU, p<0.0001).Among the nonresponder before 20, record by the PCR during the treatment, 9 become HCV RNA feminine gender, and 3 reach SVR (accept 12MIU/ days for 2, accept 9MIU/ days for 1).
Based on the HCV RNA load in the 4th when week, we identify n=13 respondent (>2log declines), n=10 centre respondent's (1-2log decline) and n=5 nonresponder's (<1log decline).In the respondent, observe the decay of typical two-phase virus.Have during in the 4th week all patients (n=5) of the virological response that realize to continue after 48 weeks for the treatment of>the HCV RNA of 2log descends.IFN-alpha levels dose dependent ground increases, and reaches peak level between 48 hours and the 1st week, succeeded by stable state.The respondent realizes the IFN-alpha levels (in 4th week, average 304.0 with respect to 160.2pg/ml) higher than the nonresponder.Between 48 and 96 hours, in all patients, 1-(2-amino-4-hydroxy-6-pteridinyl)-1,2,3-propanetriol similarly increases, and has higher steady-state level in accepting 12MIU/ days patient.In all patients, B2M increases mediumly; In the respondent, observe higher baseline values (average 16.9 with respect to 13.4ug/ml).2,5-OAS level reached peak value between 24 and 96 hours, slow-decay does not have difference in respondent and nonresponder subsequently.When carrying out In vitro culture with IFN-α in Most patients, baseline T cell proliferation reduces consumingly, and this prompting is to the responsiveness of IFN-α, no matter therapeutic outcome.But, at T=24 hour, in the nonresponder, observe IFN-α about the desensitization of T cell proliferation to cell especially.When external use IFN-α cultivates, baseline IFN-y production is the variable between the patient.When external use IFN-α cultivates, T=0 and T=24 hour, in limited nonresponder's group, observe the unresponsiveness that IFN-γ produces.
AE in most of the cases is slightly to moderate, and is the typical case of IFN-α treatment, but development stimulates and/or abscess 5 patients at the place, injection site.Reported 6 kinds of serious adverse events (SAE) in 5 experimenters, this causes the lasting interruption in 3 experimenters.All SAE are consistent with high dose IFN-α treatment.In the interruption that is caused by SAE, 2 experimenters accept 12MIU/ days, and 1 patient accepts 9MIU/ days dosage.
Clinical testing data shows that former PegIFN-α/RBV treats among the failed patient, and the continuous IFN-α treatment of high dose can be induced the strong HCV RNA decay when the 4th week.Serum interferon-alpha levels can be predicted and reply, but other immune activation mark can not.As a result, test shows, in the colony that this is difficult to treat, uses the continuous pump treatment, can send safely the dosage of IFN-α.The typical relevant AE of IFN-α shows dose dependent.In deliberately treatment was analyzed, it was 20% (6/30) that SVR leads.In meeting program analysis, it is 25% (6/24) that SVR leads, and wherein 4 in 6 of high dose group reach SVR.By the successful management of side effect, sending continuously of IFN-α can show significant clinical benefit.Interesting ground, before the treatment beginning and soon afterwards, external T cell and IFN-γ propagation can identify unlikely makes the patient who replys.
