Pomerantz Law Firm Investigates Mereo BioPharma Amid Securities Fraud Claims

Investor Alert: Investigation into Mereo BioPharma Group plc

The Pomerantz Law Firm has announced an investigation concerning Mereo BioPharma Group plc (NASDAQ: MREO) on behalf of concerned investors. This investigation comes in light of alarming reports regarding the company's Phase 3 clinical trial results for setrusumab, a treatment designed to address issues related to bone metabolism.

Background of the Investigation

Mereo's financial integrity has come under scrutiny due to assertions that the company, along with some of its executives and board members, may have perpetrated securities fraud or engaged in unlawful business practices. Investors may find it critically important to evaluate their legal options in light of these allegations.

Among the pivotal moments of concern was an announcement made by Mereo during the pre-market hours on December 29, 2025, which revealed lackluster outcomes from two Phase 3 studies of setrusumab. Notably, neither trial met its primary endpoints related to the reduction of annualized clinical fracture rates when compared to placebo or the traditional treatment, bisphosphonates. This disappointing news prompted a sharp decline in the company's stock price, dropping by $2.02 or nearly 88%, to settle at a mere $0.28 per share after the announcement.

What the Trial Results Indicated

While the primary endpoints were not reached, both trials showed positive results in secondary metrics, specifically achieving statistically significant improvements in bone mineral density when juxtaposed with their respective comparators. However, the glaring absence of progress on the primary endpoints has raised red flags among analysts and investors alike. Furthermore, the safety profile of the treatment appears unchanged, further complicating the narrative surrounding Mereo's current financial health and future prospects.

This situation has prompted an outcry among the investor community, as many are now questioning the viability of their investments in Mereo and whether they were adequately informed about the risks involved in these clinical trials. Their concerns have opened pathways for potential legal avenues against the company, highlighting the role of investor protection in such scenarios.
