VBI Vaccines Reports Rapid Seroprotection Results from an Interim Analysis of a Phase IV Postmarketing Study of its Sci-B-Vac Hepatitis B Vaccine
98.8% of Patients Seroprotected at Two Months Following Second Dose of Sci-B-Vac
CAMBRIDGE, MA (November 14, 2016) - VBI Vaccines Inc. (Nasdaq: VBIV) (TSX: VBV) (VBI) today reported interim results from an ongoing Phase IV postmarketing study to evaluate Sci-B-Vac, VBIs licensed third-generation hepatitis B vaccine, in healthy adults.
In its interim analysis, Sci-B-Vac was found to be well-tolerated and demonstrated rapid onset of protection against the hepatitis B virus (HBV). Seroprotection rates, the percent of patients who produced an antibody response capable of preventing an infection, were as follows:
- 91.9% of study participants were seroprotected at Month 2, one month after receiving a second dose of Sci-B-Vac.
- 98.8% of participants were seroprotected at Month 3, two months after receiving a second dose of Sci-B-Vac, and prior to receiving a third dose.
These interim results further demonstrate that Sci-B-Vac can safely and reliably be used to prevent HBV infection, said Dr. Francisco Diaz-Mitoma, M.D., Ph.D., VBIs Chief Medical Officer. In addition, the results add to a growing body of evidence that suggests persons receiving Sci-B-Vac may develop seroprotection against HBV after receiving just two doses of the vaccine.
We are also in the process of eliciting feedback on our late-stage clinical development plan from European and North American regulatory bodies, said Jeff Baxter, VBIs President and CEO. This encouraging data adds to our excitement about the potential of Sci-B-Vac to protect against HBV infection in major global markets.
This Phase IV study is for routine quality control purposes and to support the existing licensure of Sci-B-Vac in Israel. The study is further designed to validate VBIs new in-house reference standard vaccine for routine quality control purposes, in accordance with the European Pharmacopeia and Israeli Ministry of Health guidelines. The study also seeks to characterize the safety and immunogenicity of Sci-B-Vac to further support planned pivotal clinical trials in Europe and North America. VBI will continue to gather and analyze study data, with final results anticipated in the second half of 2017.
Study Design
This Phase IV study is an open label, single arm, single center clinical study now underway in Israel. VBI enrolled 88 healthy, HBV-seronegative males and females between 20 and 40 years of age. Study participants were vaccinated three times with 10 micrograms/ml of Sci-B-Vac at zero, one, and six months.
The primary endpoint is seroprotection rate. Successful seroprotection against HBV infection is defined by rate and by an anti-HBV surface antibody (anti-HBs) titer of 10 mIU/ml following immunization.
About Sci-B-Vac
Sci-B-Vac is a licensed third-generation hepatitis B vaccine that has demonstrated safety and efficacy in over 300,000 patients. Sci-B-Vac is currently approved for use in Israel and in 14 other countries. In contrast to second-generation hepatitis B vaccines, which contain only one surface antigen (the S antigen), Sci-B-Vac contains the S antigen and the pre-S1 and pre-S2 surface antigens. The composition of Sci-B-Vac may provide more opportunities for the immune system to respond with antibodies that can recognize one or more components of the hepatitis B virus.
