Palvella Therapeutics (PVLA) said Wednesday that no additional efficacy study has been planned for Qtorin rapamycin in microcystic lymphatic malformations to support the planned submission of a new drug application in H2.
The company said that based on the minutes of its pre-NDA meeting with the US Food and Drug Administration, the planned filing would be supported by the existing evidence package.
The evidence package will include efficacy and safety results from a phase 3 trial, data from a phase 2 study used as basis for Qtorin rapamycin's breakthrough therapy designation, as well as real-world evidence from published literature and clinical experience with off-label rapamycin in microcystic lymphatic malformations, according to the company.
