A Randomized Phase I Study of a Hepatitis B Antigen Combined With IMP321
A Phase I, Single-Blind Study to Determine the Safety, Tolerability and Pharmacodynamic Profiles of a Hepatitis B Antigen Combined With IMP321 Versus the Hepatitis B Antigen Alone and a Reference Vaccine in Healthy Young Male Volunteers

Descripción detallada
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.
