Pipeline
Solutions for unmet medical needs
We are advancing a pipeline of allogeneic, off-the-shelf virus-specific T cell (VST) therapies to treat or prevent life-threatening viral diseases with limited to no treatment options in immunocompromised patients.

Posoleucel targets six devastating viral pathogens: adenovirus (AdV), BK virus (BKV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus 6 (HHV-6), and JC virus (JCV), and has the potential to transform care for transplant recipients.

Definitions
Allo-HCT: allogeneic HCT; Auto-HCT: autologous HCT; POC: Proof-of-concept; High-risk general population: immunocompromised cancer patients, the elderly and very young.
Expanded Access Policy
Enrolling in a clinical trial is the most common way that persons who seek access to an investigational drug may receive that drug, and AlloVir’s clinical studies should be the primary route by which patients receive access to AlloVir’s investigational drug(s).
We treat individuals at high risk
Our allogeneic, off-the-shelf VST candidates benefit patients with T cell deficiencies, including transplant recipients, immunocompromised cancer patients, the elderly and the very young, who are at a higher risk of the devastating consequences of viral diseases.
