(CRXL) said initial data from a phase I trial involving Merck & Co., Inc.'s, experimental HIV vaccine look encouraging. The HIV vaccine, based on a recombinant adenovirus, is produced on Crucell's proprietary PER.C6 cell technology platform to facilitate the industrial-scale manufacturing of a safe vaccine to meet global demand.
The data, presented at the 9th Conference on Retroviruses and Opportunistic Infections in Seattle, show that the vaccine for both the prevention and treatment of HIV was generally well-tolerated by the healthy volunteers enrolled in the study and generated a substantial and prolonged specific T cell response. In comparison to vaccinations with naked DNA, the adenovirus-based vaccine showed a stronger anti-HIV immune response.
Merck & Co. has stressed that the data are preliminary and inconclusive as the phase I trial is still ongoing and that it is too early to speculate on when data of the entire phase I trial will be presented. Last month, Merck & Co. released data showing that monkeys that had been given the vaccine did not develop AIDS after being infected with an HIV-like virus. According to UNAIDS, five million people were infected with HIV in 2001, bringing the total number of people living with HIV to 40 million.
Crucell's CEO Dinko Valerio said that though the results are preliminary and inconclusive, research is on the right track. "The data further confirm that Merck & Co.'s adenovirus-based HIV vaccine is one of the most promising candidates to date. Crucell ...
