AlloVir ($ALVR) has reached a settlement with investors over claims that it misled them about the effectiveness of its lead product, Posoleucel.

Outline

In early 2023, Allovir was accused by independent monitors of hiding that AlloVir’s Phase 3 trials for posoleucel were unlikely to succeed. When the company terminated all three trials and revealed the negative results in December 2023, $ALVR fell over 67%. By March 2024, Allovir faced a lawsuit from investors.

Timeline
  • January 10, 2023 – Independent monitors allegedly determined that AlloVir’s Phase 3 trial for posoleucel was unlikely to succeed, but the company continued the trials without disclosure.
  • December 22, 2023 – AlloVir terminated all three Phase 3 trials, revealing the negative trial results. $ALVR fell over 67% on the news.
  • March 2024 – Investors filed a lawsuit, alleging AlloVir hid key trial failures and misled them about posoleucel’s approval chances.
  • February 2025 – AlloVir agreed to settle to resolve investor claims.
Background

AlloVir is a biotech company that focused on developing posoleucel, a treatment for transplant patients vulnerable to viral infections. After promising Phase 2 results, AlloVir moved forward with three Phase 3 trials in 2022–2023.

However, internal monitoring reviews determined early on that the trials were unlikely to succeed. Despite these warnings, AlloVir continued to promote the trials and sold millions of dollars in stock.

When the company finally announced the trial failures in December 2023, $ALVR collapsed by 67% in a single day.

By March 2024, investors sued, alleging that AlloVir misled them about the drug’s commercial prospects.
