FDA Denies Petitions, Approves Nocdurna
CDER has denied two petitions asking it to deny approval for a Ferring NDA for Nocdurna (desmopressin) sublingual tablets to treat nocturia due to nocturnal polyuria, and has approved the Nocdurna NDA. The denial letter says the petitions were submitted by Serenity Pharmaceuticals and Avadel Specialty Pharmaceuticals. The letter notes that FDA approved an Avadel NDA for Noctiva 3/3/17.
Each petition argued against approving the Nocdurna NDA for varied reasons. Serenity said that there was no reason for FDA to approve another drug that may be less safe and effective for the same clinical indication. Avadel asked that the agency not approve a desmopressin NDA unless specific conditions it called for were met. FDA said it considered all the issues and denied the petitions.
The denial letter says the agency properly applied the same approval standards to both the Nocdurna and Noctiva applications. For the Nocdurna application, the letter says, “FDA is satisfied that Ferring presented substantial evidence of effectiveness and that the benefits of Nocdurna outweigh its risks when used in accordance with its approved labeling.”
