Detaljert beskrivelse
In each cohort, 8 subjects will receive the hepatitis B antigen (10 µg) with IMP321 at one dose, 2 subjects will receive the reference hepatitis B antigen (10 µg) alone with physiological saline and 2 subjects will receive the commercial vaccine Engerix B® (20 µg).
Engerix B® will be administered intramuscularly. The other treatments will be administered subcutaneously.
The four successive cohorts of volunteers will be:
Cohort A:
- 8 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with IMP321 (3 µg),
- 2 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with physiological saline,
- 2 subjects treated by the commercial hepatitis vaccine Engerix B® (20 µg HBsAg with alum).
If the tolerability of this cohort is acceptable, the following cohort will be done.
Cohort B:
- 8 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with IMP321 (10 µg),
- 2 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with Physiological saline,
- 2 subjects treated by the commercial hepatitis vaccine Engerix B® (20 µg HBsAg with alum).
If the tolerability of this cohort is acceptable, the following cohort will be done.
Cohort C:
- 8 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with IMP321 (30 µg),
- 2 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with physiological saline,
- 2 subjects treated by the commercial hepatitis vaccine Engerix B® (20 µg HBsAg with alum).
If the tolerability of this cohort is acceptable, the following cohort will be done.
Cohort D:
- 8 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with IMP321 (100 µg),
- 2 subjects treated by hepatitis B antigen (10 µg HbsAg, subtype adw, without alum) with physiological saline
- 2 subjects treated by the commercial hepatitis vaccine Engerix B® (20 µg HBsAg with alum).
Blood samples will be collected on the morning of days 1, 29, 36, 57 and 85 for pharmacodynamic evaluation.
Monitoring for the occurrence of adverse events (AE), changes in physical examination, vital signs (blood pressure, pulse rate, respiration), electrocardiograms (ECG) and clinical laboratory tests (biochemistry, haematology, urinalysis) will be performed before and after each dose of the study drug to assess safety and tolerability.

- with any clinically significant abnormality following review of pre-study laboratory tests and full physical examination ;
- who have received any experimental drug within the exclusion period defined in the National Register for Healthy Volunteers of the French Ministry of Health ;
- who forfeit their freedom by administrative or legal award or who were under guardianship ;
- unwilling to give their informed consent ;
- who present a positive laboratory test for Hepatitis B surface antigen (HbsAg), HBc antibodies, HIV 1 and 2 antibodies and HCV antibodies ;
- who have a history of allergy or intolerance to the study drug ;
- who had a history of serious allergy, asthma, allergic skin rash or sensitivity to any drug ;
- who are known or suspected alcohol or drug abusers ;
- who present a positive laboratory test for urine drug screening (opiates, barbiturates, amphetamine, cannabis) ;
- who undergo surgery or have donated blood within 1 month prior to the start of the study ;
- who have taken any prescribed or over the counter drug (including antacid drug), with the exception of paracetamol (up to 3 g per day) within 1 week prior to the first dose administration ;
- who receive any drug known to affect hepatic metabolism like cimetidine, ketoconazole, fluconazole, itraconazole, phenytoin, rifampicin, rifabutin within 1 month prior to the first dose administration ;
- who receive any drug known to affect renal tubular secretion like probenecid, beta-lactam antibiotics within 2 weeks prior to the first dose administration ;
- who present any clinical condition or prior therapy which, in the opinion of the investigator, made the subject unsuitable for the study.
