FDA Cites Krazati Provider Web Page
The CDER Office of Prescription Drug Promotion (OPDP) says a Web page targeting providers with information on the efficacy of Mirati Therapeutics’ Krazati (adagrasib) tablets, for oral use, as shown in the KRYSTAL-1 trial, makes false or misleading claims about the drug’s benefits. An 8/1 untitled letter says the violations are particularly concerning because the promotional communication makes misleading representations about Krazati efficacy in patients with KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer. The letter says the FDA Bad Ad program has received multiple complaints about the Web page.
OPDP says Krazati is indicated for treating adults with KRAS G12C-mutated locally advanced or metastatic non-small cell lung cancer as determined by an FDA-approved test, who have received at least one prior systemic therapy. The indication was approved under accelerated approval based on objective response rate and duration of response.
The letter details listings in the Web page’s Efficacy menu section covering some efficacy metrics. OPDP challenges the listings and their supporting data, saying the trial was not designed to evaluate the claimed results.
Mirati was told to respond with a list of all its Krazati promotional materials that make similar representations and a plan for either discontinuing such communications or stopping the distribution of the drug.
