425: Minovia Therapeutics Reports Positive Interim Phase 2 Data for MNV-201 in Pearson Syndrome and Announces SPAC Merger

Minovia Therapeutics announced positive interim Phase 2 trial results for MNV-201 in Pearson Syndrome, showing a favorable safety profile and preliminary efficacy signals, alongside progress towards a business combination with Launch One Acquisition Corp.

Summary

• Interim results from the ongoing Phase 2 trial of MNV-201 in Pearson Syndrome demonstrated a positive safety profile, meeting the primary safety endpoint.
• No treatment-related severe adverse events (SAEs) were reported, and no anti-mitochondrial antibodies were detected; most adverse events were transient and resolved within four days, primarily associated with the apheresis procedure.
• Preliminary efficacy data at the six-month follow-up indicated improved growth parameters (height standard deviation score) for two of the first three patients, and quality of life scores also showed improvement for two of these patients.
• Data from two compassionate use patients with Kearns-Sayre syndrome (KSS) also showed a favorable safety profile and improved quality of life scores.
• The FDA granted MNV-201 both Fast Track and Rare Pediatric Disease Designation, which can accelerate development and review, and potentially lead to a pediatric priority review voucher (PRV) historically valued over US$100 million, though the PRV program is currently on hold.
• Minovia entered a definitive business combination agreement with Launch One Acquisition Corp. (Nasdaq: LPAA), with the combined company expected to trade on Nasdaq under a new ticker symbol following the projected closing in late 2025.
• The Phase 2 trial is expected to conclude before the end of 2025, and registrational studies are anticipated to initiate in 2026.
