Larimar Therapeutics Reports Topline Phase 1 Clinical Trial Data Showing Dose-Dependent Increases In Frataxin Levels in Patients With Friedreich's Ataxia

Larimar Therapeutics, Inc. ("Larimar") (NASDAQ:LRMR), a clinical-stage biotechnology company focused on developing treatments for Friedreich's ataxia (FA) and other complex rare diseases, today announced topline data from its Phase 1 multiple ascending dose (MAD) clinical trial (n=27) evaluating CTI-1601 as a treatment for FA.

FA patients participating in the trial received subcutaneous injections of CTI-1601 or placebo at increasing dose levels and frequencies over a 13-day period. Patients in Cohort 1 were dosed with 25 mg of CTI-1601 or placebo daily for four days, and then every third day until Day 13. Cohort 2 patients were dosed with 50 mg of CTI-1601 or placebo daily for seven days, and then once every other day until Day 13. Patients in Cohort 3 received daily injections of 100 mg CTI-1601 or placebo for thirteen days.

Data show that repeated subcutaneous administration of CTI-1601 resulted in dose-dependent increases in frataxin (FXN) levels from baseline compared to placebo controls. These dose-dependent increases in frataxin levels were seen in all evaluated tissues (buccal cells, skin biopsies, and platelets) with daily dosing. The median change from baseline in frataxin levels observed for each dosing group and tissue are shown in the table below.
