An Open-Label, Multicenter, Phase 2 Study of the Safety and Efficacy of KRT-232 in Subjects With Relapsed or Refractory Small Cell Lung Cancer (SCLC)
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, for the treatment of patients with relapsed or refractory small cell lung cancer. This study will be conducted in 2 parts. Part 1 will evaluate two treatment arms, each with a different KRT-232 dose. Part 2 will continue the evaluation of the selected treatment arms from Part 1.
• Histologically or cytologically confirmed diagnosis of SCLC documented as TP53WT
• Disease must be measurable per RECIST Version 1.1
• Evidence of radiographic progression during or after at least one prior platinum-containing therapy with no curative therapy available. Subjects who have received only one prior line of therapy must not be candidates for platinum-based regimens at relapse.
• Subjects must have received a checkpoint inhibitor (PD-1 or PD-L1) unless contraindicated if checkpoint inhibitors are approved and available.
• ECOG ≤ 2
