Not heeding earlier FDA advice has earned Levo Therapeutics Inc. a complete response letter (CRL) for its NDA seeking approval for intranasal carbetocin (LV-101) in hyperphagia associated with Prader-Willi syndrome (PWS). The CRL followed a 12-1 negative advisory committee vote in November.
Compelling testimony from parents who saw life-altering changes in their children who participated in Levo Therapeutics Inc.’s intranasal carbetocin clinical trial wasn’t enough to counter what the FDA’s Psychopharmacologic Drugs Advisory Committee saw as a lack of “substantial evidence” to support the drug’s effectiveness in treating hyperphagia associated with Prader-Willi syndrome (PWS).
The FDA has one question for its Psychopharmacologic Drugs Advisory Committee when it meets Nov. 4: Has Levo Therapeutics Inc. provided substantial evidence that the company’s carbetocin nasal spray is effective in treating hyperphagia associated with Prader-Willi syndrome?
While privately held Levo Therapeutics Inc.’s phase III study of LV-101 (intranasal carbetocin) for treating Prader-Willi syndrome (PWS) failed to meet its primary outcome measurements, the company’s CEO told Bioworld the first secondary endpoint showed a statistical significance that raised her hopes the FDA might approve the selective oxytocin-receptor agonist for the indication.
