Larimar Therapeutics Provides Update on CTI-1601 Clinical Program

BALA CYNWYD, Pa., Feb. 14, 2022 (GLOBE NEWSWIRE) -- Larimar Therapeutics, Inc. (“Larimar”) (Nasdaq: LRMR), a clinical-stage biotechnology company focused on developing treatments for complex rare diseases, today announced that it has received feedback from the U.S. Food and Drug Administration (FDA) regarding the clinical hold on Larimar’s CTI-1601 program. FDA stated it is maintaining its clinical hold at this time and that additional data is needed to resolve the clinical hold. Larimar is further analyzing previously completed studies, and is evaluating if additional studies are warranted. The Company also intends to engage FDA to determine how best to provide these data. Larimar is currently reassessing guidance on the timing of the planned Jive open-label extension and pediatric multiple-ascending dose clinical trials as it works to meet the agency’s request.

“Patient safety is our top priority,” said Carole Ben-Maimon, MD, President and Chief Executive Officer of Larimar. “Our next step is to engage with the agency to determine how we can meet their request in the most efficient and expeditious manner. Based on all available clinical and non-clinical data, we continue to believe there is a path forward through the resolution of the CTI-1601 clinical hold. We have a robust Phase 1 dataset, which demonstrates proof-of-concept for CTI-1601 as a frataxin replacement therapy and its differentiated mechanism of action (MOA). We believe this MOA leaves CTI-1601 uniquely positioned to address the urgent need for disease modifying therapies in Friedreich’s ataxia (FA), as it is designed to address the root cause of this devastating disease. We remain committed to CTI-1601’s further development and are working towards this goal with a strong cash position which provides runway at least into 2023. We intend to operate under a cost reduction plan while resolving the clinical hold to manage burn and extend our cash runway if needed.”

The CTI-1601 program was placed on a clinical hold by the FDA following the Company’s notification to the agency of mortalities which occurred at the highest dose levels in a 26-week non-human primate (NHP) toxicology study that was designed to support extended dosing of patients with CTI-1601. At the time of the notice, Larimar had no interventional clinical trials with patients enrolled or enrolling. The recent feedback from the FDA follows Larimar’s submission of a complete response including a comprehensive study report from the 26-week NHP toxicology study.

Data from the Phase 1 single- and multiple-ascending dose (MAD) clinical trials indicated that repeated subcutaneous injections of CTI-1601 were generally well tolerated at doses up to 100 mg administered daily for up to 13 days. No serious adverse events, important medical events, or treatment-related severe adverse events were reported in the trial and the number and severity of adverse events did not increase with increasing exposure to CTI-1601. The most common adverse events were mild and moderate injection site reactions. Data from the MAD trial also showed that daily subcutaneous injections of CTI-1601 at doses of 50 mg or 100 mg resulted in frataxin levels in peripheral tissues (buccal cells) that were at or in excess of those that would be expected in phenotypically normal heterozygous carriers.

About CTI-1601
CTI-1601 is a recombinant fusion protein intended to deliver human frataxin into the mitochondria of patients with Friedreich’s ataxia who are unable to produce enough of this essential protein. CTI-1601 has been granted Rare Pediatric Disease designation, Fast Track designation and Orphan Drug designation by the U.S. Food and Drug Administration (FDA), Orphan Drug Designation by the European Commission, and PRIME designation by the European Medicines Agency.
