VALENCIA, Calif. — It seems that MannKind has experienced a setback with a drug designed to control hyperglycemia in Type 1 and Type 2 diabetes patients.
The Food and Drug Administration on Thursday issued a complete response letter to the drug maker regarding Afrezza (insulin human [rDNA origin]) inhalation powder. The regulatory agency requested that the company conduct two clinical trials, one in patients with Type 1 diabetes and one in patients with Type 2 diabetes, with its next-generation inhaler, to assure it works as effectively as MedTone, its predecessor.
