Inovio Pharmaceuticals (NASDAQ:INO) announced its HIV vaccine produced a high immune response rate in human studies.
As quoted in the press release:
The vaccine candidate, PENNVAX-GP, consists of a combination of four HIV antigens designed to cover multiple global HIV strains and generate both an antibody (humoral) immune response as well as a T cell (cellular) immune response to both potentially prevent and treat HIV.
These preliminary results are from a study supported by the HIV Vaccine Trials Network (HVTN) and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) in collaboration with Inovio. The study evaluated a four-dose regimen of PENNVAX-GP DNA vaccine administered by intradermal (ID) or intramuscular (IM) administration in combination with a DNA encoded immune activator, IL-12 (INO-9012). Overall, 71 of 76 (93%) evaluable vaccinated participants showed a CD4+ or CD8+ cellular immune response to at least one of the vaccine antigens (env A, env C, gag, or pol). Similarly, 62 of 66 (94%) evaluated participants demonstrated an env specific antibody response. None of the placebo recipients (0 of 9; 0%) demonstrated either a cellular or an antibody response in the study. Notably, amongst the participants receiving PENNVAX-GP vaccine and IL-12 with intradermal immunization, 27 of 28 (96%) participants demonstrated a cellular response and 27 of 28 (96%) demonstrated an HIV env specific antibody response.
