What the Analysts think about MREO

Analyst ratings (Buy, Hold, Sell) for Mereo BioPharma Group stock.

Bulls say / Bears say

Strong cash position: $62.5 million as of March 31, 2025, anticipated to fund operations into 2027, lessening near-term financing risk and backing late-stage development (Reuters).
Multiple regulatory designations: setrusumab has orphan drug status from both the EC and FDA, PRIME designation from the EMA, and Breakthrough Therapy designation from the FDA; alvelestat received a positive EMA opinion on orphan designation (final decision expected Q1 2025), strengthening approval prospects (Reuters).
Phase 3 program remains on track: global Orbit and Cosmic studies for setrusumab are progressing toward a second interim analysis in mid-2025 and final data in Q4 2025, with consistent safety profiles supporting continued clinical momentum (Reuters).
Shares plunged 33.7% on July 10, 2025 after the Orbit Phase 3 trial failed to meet early stopping criteria, highlighting high clinical risk and increased investor volatility (Barron's).
The second interim analysis of the setrusumab trial did not reach the statistical threshold for early termination, pointing to efficacy challenges and a longer runway to possible approval (Barron's).
Ultragenyx’s gene therapy (UX111) received a complete response letter from the FDA due to manufacturing concerns, reflecting possible regulatory execution issues for Mereo’s key partner and a risk that resources could be diverted (Reuters).
