This is a Phase 3 study to evaluate posoleucel (ALVR105, Viralym-M); an allogeneic, off-the-shelf multi-virus specific T cell therapy that targets six viral pathogens: BK virus, cytomegalovirus, adenovirus, Epstein-Barr virus, human herpesvirus 6 and JC virus.
Phase 2/3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Assess the Safety and Efficacy of ALVR105 Posoleucel (ALVR105,Viralym-M) Compared to Placebo for the Prevention of AdV, BKV, CMV, EBV, HHV-6, and JCV Infection and/or Disease, in High-Risk Patients After Allogeneic Hematopoietic Cell Transplant
This is a Phase 2/3, multicenter, randomized, double-blind, placebo controlled trial comparing posoleucel to placebo for the prevention of infection or disease due to AdV, BKV, CMV, EBV, HHV-6, or JCV in high-risk adult and pediatric patients after allogeneic HCT.
There are 2 parts to the study, a Phase 3 randomized study cohort described in this posting, and an open label Phase 2 cohort described in NCT04693637, which has completed enrollment. In this Phase 3 part, approximately 302 eligible allogeneic HCT recipients will be enrolled and will receive 7 doses of posoleucel or placebo over 12 weeks, followed by a 12 week follow-up period.
