MAIA Biotechnology (MAIA) said Wednesday initial efficacy data from its phase 2 part C expansion trial of ateganosine showed a 90.5% interim disease control rate in patients with advanced non-small cell lung cancer.
The company said 21 patients received ateganosine followed by Regeneron Pharmaceuticals' (REGN) Libtayo in 21-day treatment cycles.
MAIA added that the initial efficacy results were consistent with the results of the part A and part B studies, despite the part C trial enrolling a more heavily pre-treated patient population.
MAIA Biotechnology shares were down 2.4% in Wednesday trading.
