Refractory Tumor

This study is a first-in-human, open-label, 2-part, Phase 1 dose escalation study of DO-2, administered orally to patients with advanced or refractory solid tumours, with MET aberrations, and no available, approved therapeutic alternative. The dose escalation is completed, Part 2 of the study is ongoing.

Lung cancer is the most common cause of cancer-related death worldwide. Approximately 85% to 90% of lung cancer cases are non-small cell lung cancer (NSCLC), of which KRAS is one of the most common driver genes, occurring in 25-30% of lung adenocarcinomas and 3-5% of squamous cell carcinomas. KRAS-mutant NSCLC had been considered undruggable in past decades. This research sought to address a significant challenge in treating NSCLC with KRAS mutations, which are notoriously difficult to target effectively. Here, we proposal that the combined use of anlotinib and trametinib combined with tislelizumab may form an effective strategy for the treatment of KRAS-mutant NSCLC patients.
