Healthy Clinical Trial
Official title:
A Phase 1 Monotherapy Study to Evaluate the Safety, Tolerability & Immunogenicity of Vaccination With Candidate Chimpanzee Adenovirus-vectored HepB Virus Vaccine ChAdOx1 HBV in Healthy Participants & Participants With Chronic HepB Infection
This is a Phase 1, first in human study of ChAdOx1-HBV. The study will be conducted in 40 healthy participants and 12 participants with CHB and virally suppressed with oral antiviral medication. This will be an open-label, non randomised dose escalation study comparing the safety, tolerability and immunogenicity of 2 different doses of ChAdOx1 HBV vaccine. T cell responses in healthy participants who have received a prior two-dose series of AZD1222 will be compared with those who have received either the Pfizer COVID 19 vaccine or the Moderna mRNA COVID 19 vaccine.
This is a first in man human study of a therapeutic vaccine for chronic hepatitis B infection(ChAdOx1-1HBV). The vaccine will be given to participants in a dose escalation strategy (two doses). Five healthy participants will be administered the low dose first (cohort 1). Dose escalation will only be initiated in the next 5 healthy participants (cohort 2) following Safety Monitoring Committee (SMC) review. Six CHB participants will be administered the low dose (cohort 3) before the dose escalation is initiated in the remaining 6 CHB participants (cohort 4). Thirty healthy participants (15 who have received two doses of AZD1222 [cohort 5] and 15 who have received at least two prior doses of Pfizer/Moderna mRNA COVID 19 vaccine [cohort 6]) will be dosed in parallel with the high dose used in cohorts 2 and 4. Each participant will receive 1 dose of the vaccine (intramuscular injection). Participants (Volunteers & patients) in cohorts 1 to 4 will attend up to 9 study visits and cohorts 5 & 6 will attend up to 4 visits in total. The last visit will be 24 weeks after vaccination for cohorts 1 to 4 and 12 weeks for cohorts 5 & 6. ;
