About

This is Phase I, randomized, open-label, active-controlled study to evaluate the safety, tolerability, and immunogenicity of a hepatitis B vaccine administered trans-dermally via microneedle array patch (MAP) compared to the intra-muscular (IM) hepatitis B vaccine (Euvax B™), administered at Day (D) 0, Week (W) 4, W26 among healthy adults aged 19 to 40 years in the Republic of Korea.

Full description

This is Phase I, randomized, open-label, active-controlled study to evaluate the safety, tolerability, and immunogenicity of a hepatitis B vaccine administered trans-dermally via microneedle array patch (MAP) compared to the intra-muscular (IM) hepatitis B vaccine (Euvax B™), administered at Day (D) 0, Week (W) 4, W26 among healthy adults aged 19 to 40 years in the Republic of Korea.

Healthy adults between 19 to 40 years of age will be screened for eligibility criteria. A total of 40 subjects will be enrolled, 30 subjects administered trans-dermally via MAP and 10 subjects administered with active comparator vaccine via intramuscular injection. Subjects will be randomized to either transdermal MAP arm or IM Injection arm with ratio of 3:1. At D0, subject will receive 1st vaccination, followed by 2nd and 3rd vaccination at W4 and W26, respectively.

For the first five (5) subjects who completed Week 1 visit, all available clinical laboratory and adverse event data will be reviewed in a rolling manner by Study Medical Monitor and Site PI. Further enrollment will be paused during safety review by the independent data safety monitoring board (DSMB). If there are no safety findings judged to be of clinical concern and has not met the trial halting criteria specified in the protocol section 10.1.4, subsequent dosing (2nd dose) will be opened for the first 5 subjects and enrollment of the remaining 35 subjects will begin. If any of the halting rules are met, the study will be halted immediately for DSMB review/recommendation.

After all enrolled subjects complete Visit 6 (4 weeks after 3rd dose), the DSMB will be convened to review the safety and immunogenicity data once available to look at the sero-protection rates and titers to formulate further recommendations and be diligent in case there are non-responders to MAP Hep B vaccine. All SMC and DSMB meetings will be conducted per SMC and DSMB charter, respectively.

The solicited and unsolicited adverse events will be recorded up to 7 days and 28 days, respectively for each injection. Relatedness of all adverse events that occurred in the MAP arm will be assessed to biologics component (active ingredient; HBsAg) as well as medical device component (microneedle patch). Serious adverse events (SAEs) and adverse events of special interest (AESIs) will be collected throughout the study.

Should the criteria for any temporary pause of immunization rule be met, at any time, further enrollment and administration of investigational product will be paused for further evaluation. The Sponsor will consult the DSMB, if needed, to determine whether to enroll and/or continue enrollment and/or dosing of remainder of the subjects.

All subjects will be followed for 52 weeks following the 1st vaccination. Week 52 of the last subject enrolled will be the End of Study (EOS) visit.
