When the Food and Drug Administration approved Heplisav-B Nov. 9, it marked the first new vaccine for hepatitis B virus (HBV) to be sanctioned in over 25 years.
Heplisav-B is the only two-dose regimen that protects against all known subtypes of HBV in adults 18 years and older, according to a statement released by Dynavax Technologies, the creator of the drug.
“Heplisav-B is the first FDA-approved product for Dynavax and demonstrates our ability to develop innovative products and progress them from discovery to commercialization,” according to Eddie Gray, chief executive officer of Dynavax. “We expect that it will become an essential tool in the public health community’s fight to prevent hepatitis B [infection], and we look forward to making Heplisav-B available to clinicians and their adult patients.”
Incidence of HBV has increased sharply from 2012 to 2015 in the United States, with reported cases rising from 2,895 to 3,370, according to the Centers for Disease Control and Prevention.
From 2014 to 2015, acute HBV infection increased 20.7%, according to the CDC report.
The new vaccine’s approval came after review of safety and efficacy data from three phase 3 trials comparing Heplisav-B with Engerix-B, another HBV vaccine currently available, that is given in a three-dose regimen.
In one study of 2,032 patients between the ages of 18 and 55 years, seroprotection rate in the Heplisav-B group (1,511) was 95%, compared with 81.5% in the Engerix-B group (521).
Heplisav-B patients were given a two-dose regimen of the drug at 0 and 1 months, followed by a placebo at 6 months, while investigators administered Engerix-B at all three intervals in the comparator subjects.
The FDA’s decision to green-light the new vaccine follows a recommendation for approval from the FDA’s Vaccines and Related Biological Products Advisory Committee, held at the end of July this year.
During the advisory committee meeting, members were concerned about an increased relative risk for acute myocardial infarction of 6.97 in Heplisav-B patients (14), compared with Engerix-B patients (1).
The recommendation for approval came with the caveat of conducting postmarketing analysis for the risk of AMI in Heplisav-B patients, which Dynavax is conducting through the Kaiser Permanente system in California.
“To evaluate the risk of AMIs, the study will enroll 25,000 Heplisav-B patients and 25,000 Engerix-B patients over approximately 10 months and follow them for 1 year after vaccination,” according to a statement from Dynavax. “In addition we will evaluate the rate of immune-mediated diseases in these patients in an additional 5,000 Heplisav-B recipients and 5,000 Engerix-B recipients.”
Dynavax is currently set to introduce Heplisav-B commercially in the United States in 2018, with the cost of the drug set to be released soon.
“Dynavax is in the process of finalizing the price of a two-dose series of Heplisav-B, and they plan to disclose it shortly after approval,” according to the company. “Their pricing and access strategy will be aimed at ensuring that populations at risk of infection are able to access this new vaccine, while recognizing the value it brings to the health care system with a two-dose regimen and higher rates of protection compared to Engerix-B.”
