Minovia Therapeutics Announces Interim Data from Phase 2 Trial in Pearson Syndrome Demonstrating No Treatment-Related Serious Adverse Events and Preliminary Signal for Efficacy Measured by Growth

Data presented at the UMDF meeting highlighting first three of expected six subjects and two compassionate use patients provide encouraging results supporting continuation of trial

Haifa, ISRAEL – July 24, 2025 – Minovia Therapeutics Ltd. (“Minovia” or the “Company”), a clinical-stage biotechnology company developing novel therapies to treat mitochondrial diseases and combat age-related decline, announces positive interim results of the ongoing Phase 2 trial of the Company’s lead investigational compound MNV-201 in Pearson Syndrome, a fatal pediatric mitochondrial disease characterized by sideroblastic anemia (a disorder causing abnormal red blood cell development), failure to thrive and exocrine pancreas dysfunction. The interim analysis was presented at the United Mitochondrial Disease Foundation (UMDF) Annual Meeting on June 20, 2025. The analysis showed that MNV-201 has a positive safety profile even in this fragile patient population, currently meeting the Phase 2 trial’s primary safety endpoint.

Minovia Co-founder and CEO, Natalie Yivgi-Ohana, Ph.D., stated, “These Phase 2 data show extremely encouraging results, even in such a small patient sample. Pearson Syndrome is a devastating condition seen in young children. The clinical experience from our first-generation product helped identify a novel primary endpoint for this heterogenic group of patients and resulted in positive interactions with the FDA that could be leveraged towards MNV-201 development, enabling the current clinical trial. MAT’s unique mechanism of action provides a novel approach to addressing these devastating mitochondrial deletion syndromes. We look forward to finalizing patient recruitment and to providing the mitochondrial disease community with future updates on trial progress.”

In the presentation, Minovia’s Chief Scientific Officer Noa Sher reported no treatment related severe adverse events (SAEs) and no anti-mitochondrial antibodies were detected. In addition, all adverse events were transient in nature and the majority resolved within four days. Most adverse events were associated with the apheresis procedure necessary to procure patient-derived cells and conducted prior to the drug’s administration. In addition to safety data, Minovia is collecting preliminary efficacy data based on a novel endpoint identified through a natural history study performed at the Children’s Hospital of Philadelphia (CHOP) and supported by Minovia funding. Results indicate that at the six-month follow-up, two of the first three patients experienced improved growth parameters relative to those prior to treatment, as measured by height standard deviation score. Quality of life scores also showed improvement for two of the first three patients. The Company continues to enroll patients in the trial, which is expected to conclude before the end of 2025.

In addition to the three patients in the trial, the Company gathered data from two compassionate use patients affected by Kearns-Sayre syndrome (KSS), another mitochondrial deletion syndrome. In addition to a favorable safety profile, early data indicates improved quality of life scores for both patients.

The FDA has granted both Fast Track and Rare Pediatric Disease Designation to MNV-201, which is in Phase 2 clinical trials for the treatment of Pearson Syndrome, an ultra-rare and life-threatening mitochondrial disorder affecting children. The Company is advancing interactions with the FDA to align on a pivotal trial design and expects to initiate registrational studies in 2026.

FDA’s Fast Track Designation is designed to accelerate the development and review of therapies for serious or life-threatening conditions with unmet medical need. The designation provides Minovia with the opportunity for increased FDA interactions, potential eligibility for priority review, and the opportunity for a rolling submission of a future Biologics License Application (BLA) for MNV-201. Concurrently, Rare Pediatric Disease Designation (RPD) is granted to drugs which are under development for rare childhood diseases and provides the Company with the potential to receive a pediatric priority review voucher (PRV) if the drug is initially approved for that rare childhood disease. A PRV grants the holder an expedited six-month review of a new drug application. PRVs are tradeable and have historically commanded prices in excess of US$100 million; however, PRV programs are currently on hold awaiting reauthorization by Congress.

The Company also recently announced entry into a definitive business combination agreement (the “Business Combination Agreement”) with Launch One Acquisition Corp. (Nasdaq: LPAA, “Launch One”), a publicly traded special purpose acquisition company. Following the expected closing of the transaction contemplated by this Business Combination Agreement (the “Business Combination”), projected for late 2025, the combined company will operate as Minovia Therapeutics and trade on Nasdaq under a new ticker symbol.

About MNV-201

MNV-201 is a first-in-class cell therapy that uses Minovia’s proprietary Mitochondrial Augmentation Technology (MAT) to add healthy, energy-producing mitochondria into a patient’s own stem cells — aiming to restore organ function and improve health. In early-stage clinical studies, MAT has demonstrated a strong safety profile and signs of multi-system benefit in patients with Pearson Syndrome, including improvements in growth, muscle function, hematologic stability, and improved quality of life.

About Pearson Syndrome

Pearson Syndrome is caused by large-scale deletions in mitochondrial DNA (mtDNA) that impair the energy-generating function of cells, leading to bone marrow failure, metabolic crises, and organ dysfunction. With no approved therapies, current care is purely supportive, and patients die during childhood.

About Minovia Therapeutics

Minovia Therapeutics, chaired by John Cox, is a clinical-state biotechnology company working on treatments to replace dead or defective mitochondria with new healthy mitochondria, helping people with mitochondrial diseases and fighting aging. Its main treatment, MNV-201, is already being tested for Pearson Syndrome and Myelodysplastic Syndrome. Minovia is also developing ways to help people live longer, healthier lives. Based in Haifa, Israel, where it operates a GMP facility for mitochondrial drug substance and drug product manufacturing for clinical trials related to its therapy, Minovia is planning to expand to the U.S. For more information, visit www.minoviatx.com.

There may be additional risks that neither Launch One nor Minovia presently know or that Launch One and Minovia currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Any forward-looking statements made by or on behalf of Launch One or Minovia speak only as of the date they are made.
