FDA Delays Review Action on Liquidia NDA
FDA has told Liquidia Corp. that its earlier user fee review action target date of 1/24 will be missed on the company’s NDA for Yutrepia (treprostinil) inhalation powder for treating pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD). The agency explained that it is confirming the process for adding the PH-ILD indication as an amendment to the NDA, according to Liquidia, adding that it has not received any requests for additional clinical data to support the submission.
“We are in active communication with the FDA regarding the process we followed to amend our NDA to add PH-ILD to the labeled indication,” the company says. “Whether the NDA is amended or supplemented, we will continue to prepare for the final FDA approval of Yutrepia to treat both PAH and PH-ILD patients following the expiration of regulatory exclusivity for [United Therapeutics Corp.’s] Tyvaso on 3/31. “As communicated by the tentative approval to treat PAH, Yutrepia has already met the regulatory standards for quality, safety and efficacy.”
Liquidia notes that FDA 11/5/2021 issued a tentative approval for Yutrepia for treating PAH to improve exercise ability in adult patients with New York Heart Association (NYHA) Functional Class II-III symptoms. And last July, the company filed an amendment to the NDA that sought to add PH-ILD to the label. “The FDA previously confirmed that Yutrepia may include the treatment of PH-ILD to the proposed label for Yutrepia without additional clinical studies,” it says.
