J&J, partners to discontinue Phase 3 Mosaico HIV vaccine clinical trial

The Janssen Pharmaceutical Companies of Johnson & Johnson, together with a consortium of global partners, yesterday announced the results of an independent, scheduled data review of the Phase 3 Mosaico study of Janssen’s investigational HIV vaccine regimen. The study’s independent Data and Safety Monitoring Board, or DSMB, determined that the regimen was not effective in preventing HIV infection compared to placebo among study participants. No safety issues with the vaccine regimen were identified. In light of the DSMB’s determination, the Mosaico clinical trial will be discontinued. Participant notifications and further analyses of the data are underway. Throughout the trial, study investigators have ensured that any individuals who contracted HIV received prompt HIV treatment and care. "We are disappointed with this outcome and stand in solidarity with the people and communities vulnerable to and affected by HIV. Though there have been significant advances in prevention since the beginning of the global epidemic, 1.5 million people acquired HIV in 2021 alone, underscoring the high unmet need for new options and why we have long worked to tackle this global health challenge. We remain steadfast in our commitment to advancing innovation in HIV, and we hope the data from Mosaico will provide insights for future efforts to develop a safe and effective vaccine," said Penny Heaton, M.D., Global Therapeutic Area Head, Vaccines, Janssen Research & Development.
