Clinical Hold on Translate Bio’s MRT5201
FDA has placed on clinical hold a Translate Bio IND submission for MRT5201 for treating ornithine transcarbamylase (OTC) deficiency, due to additional clinical and nonclinical questions. The company submitted the IND in December to support the initiation of a Phase 1/2 clinical trial in patients with OTC deficiency. It says it expects to receive formal written communication with additional information from FDA in the near future and it will subsequently respond as promptly as possible.
Translate Bio says MRT5201 is designed to treat patients with OTC deficiency by intravenous delivery of mRNA encoding fully functional OTC enzyme to the liver to enable the hepatocytes to produce the normal enzyme. The therapy has been granted an orphan drug designation for treating the condition.
