Clinical Hold on LogicBio Gene Therapy
FDA has placed a clinical hold on LogicBio Therapeutics’ Phase 1/2 SUNRISE clinical trial involving LB-001 in pediatric patients with methylmalonic acidemia (MMA). According to the company, four patients have been dosed in the SUNRISE trial with LB-001, a single-administration, adeno-associated virus (AAV) genome editing therapy. One patient reportedly experienced a drug-related serious adverse event (thrombotic microangiopathy (TMA)), which it says has been previously reported in association with other AAV genetic therapies. “The patient was hospitalized and responded well to intravenous fluids and parenteral nutrition,” LogiBio says.
The company says it subsequently implemented additional safety measures in the SUNRISE trial, and reported it to FDA and the trial’s Data Safety Monitoring Board (DSMB). Last month, another patient dosed in the SUNRISE trial experienced a case of TMA. After this report, the agency notified the company that the SUNRISE trial has been placed on clinical hold. “LogicBio will be working closely with the FDA and the DSMB to determine the next steps for the SUNRISE trial and the LB-001 program,” the company says.
