Posoleucel is under clinical development by AlloVir and currently in the Phase III in clinical pathway. The characteristics of the clinical trial as well as other attributes related to the drug, regulations, and company play a fundamental role in ensuring the likelihood of transition that the drug moves from its current development stage to next.

According to GlobalData, the latest event to affect Posoleucel’s likelihood of approval (LoA) and phase transition for Hemorrhagic Cystitis (Haemorrhagic Cystitis) took place on 05 Oct 2021, which increased the likelihood that the drug progresses to the next phase in its clinical pathway and increased the likelihood of final approval for this indication.

GlobalData uses proprietary data and analytics to provide a complete picture of this assessment in their Posoleucel Likelihood of Approval (LoA) and Phase Transition Success Rate (PTSR) Report.

Posoleucel overview

Posoleucel (ALVR-105) is under development for the prophylaxis and treatment of hematopoietic stem cell transplant-associated viral infections such as refractory cytomegalovirus infection (CMV), adenovirus infection, Epstein–Barr virus infection, human herpesvirus 6 infection, hemorrhagic cystitis, BK virus infection, polyomavirus Infections (JC virus), and multi-virus infections. The drug candidate is an allogeneic, off-the-shelf multi-virus specific T-cell therapy, administered through intravenous injection and infusion. It was also under development for the prophylaxis and treatment of solid organ transplant (SOT) associated infections such as nephritis (BK-nephritis) and viral infections associated with primary immunodeficiency disorder.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
