Inhaled Gene Therapy for Lung Cancer Gets ‘Expedited’ Status
FDA has granted Krystal Biotech a Regenerative Medicine Advanced Therapy (RMAT) designation for KB707, an inhalable gene therapy being investigated for treating advanced or metastatic non-small cell lung cancer (NSCLC). KB707 is described as a redosable herpes simplex type 1 virus-based immunotherapy that is designed to deliver genes directly into a tumor to produce IL-2 and IL-12 cytokines.
“The FDA’s decision to grant RMAT designation to KB707 reflects both the urgent unmet need for new NSCLC therapies as well as the promising early clinical evidence of efficacy we have observed with inhaled KB707 in patients with advanced NSCLC,” the company says.
The designation is based on early clinical data from the ongoing Phase 1 KYANITE-1 study in patients with heavily pre-treated advanced NSCLC. According to the company, the trial has demonstrated consistent and meaningful antitumor activity, including durable responses and clinically significant tumor reductions in patients receiving inhaled KB707. Enrollment in the KYANITE-1 trial (NCT06228326) remains ongoing. Krystal says additional data will be presented at upcoming scientific meetings.
