Larimar Therapeutics Inc. said Wednesday it has been cleared by regulators to launch a 25-milligram cohort of a Phase 2 trial studying its CTI-1601 treatment for Friedreich's ataxia.

The clinical-stage biopharmaceutical company said the Food and Drug Administration cleared the cohort's initiation by lifting a full clinical hold and imposing a partial hold.

The program was previously placed on hold by the FDA after the company flagged three mortalities of 34 animals given CTI-1601 in a 26-week non-human primate toxicology study. All three deaths were in the study's two highest-dose groups.

The FDA decided to allow the upcoming Phase 2 trial after Larimar submitted a detailed analysis of its toxicology studies and Phase 1 clinical trials.

The trial is expected to start in the fourth quarter of this year, with top-line data expected in the second half of next year.

Shares edged 2.2% higher to $3.22 in premarket trading.

Friedreich ataxia is a rare inherited disease that causes progressive nervous system damage and movement problems. It usually begins in childhood and leads to impaired muscle coordination that worsens over time, according to the National Institutes of Health.
