FDA sets TRYNGOLZA review period

FDA determined TRYNGOLZA had a regulatory review period of 2,534 days (testing phase 2,289 days; approval phase 245 days). The agency verified key dates: IND effective January 13, 2018; NDA submitted April 19, 2024; NDA approved December 19, 2024. This determination establishes the maximum potential length of a patent extension for U.S. Patent No. 9,163,239 and could allow the company extra exclusivity that may affect competition and drug prices.

Company requests 1,390‑day extension

Ionis Pharmaceuticals has applied for patent term restoration for U.S. Patent No. 9,163,239 and is seeking 1,390 days of patent extension. If granted, 1,390 days would add roughly 3.8 years of additional exclusivity to the patent term.
