Turning Point Therapeutics Initiates TRIDENT-2 Clinical Study Investigating Repotrectinib-Trametinib Combination in KRAS G12D Mutated Advanced Solid Tumors
“We are pleased to initiate the TRIDENT-2 study and explore a potential new treatment option for patients with KRAS-driven solid tumors,” said
The Phase 1b portion of the study will examine the safety, tolerability, pharmacokinetics, and any early signals of efficacy of repotrectinib in combination with trametinib in patients with KRAS G12D mutated advanced solid tumors. After determination of a recommended Phase 2 combination dose, the study includes a Phase 2 dose expansion portion with the primary endpoint of objective response rate.
Results from preclinical studies presented at the 2021
The frequently mutated Kirsten Rat Sarcoma (KRAS) viral oncogene is associated with a broad range of human cancers, including approximately 30% of non-small cell lung, 40% of colorectal and more than 90% of pancreatic cancers. KRAS G12D mutations are known to occur across multiple tumors types, including an estimated 30% of pancreatic, 15% of colorectal and 5% of both endometrial and non-small cell lung cancers.
Therapeutic targeting of KRAS has proven challenging, in part due to resistance and adaptive upregulation of alternative signaling pathways that promote tumor cell survival, as well as concurrent secretion of various cytokines and growth factors.
Turning Point Therapeutics is a clinical-stage precision oncology company with a pipeline of internally discovered investigational drugs designed to address key limitations of existing cancer therapies. The company’s lead drug candidate, repotrectinib, is a next-generation kinase inhibitor targeting the ROS1 and TRK oncogenic drivers of non-small cell lung cancer and advanced solid tumors. Repotrectinib, which is being studied in a registrational Phase 2 study in adults and a Phase 1/2 study in pediatric patients, has shown antitumor activity and durable responses among kinase inhibitor treatment-naïve and pre-treated patients. The company’s pipeline of drug candidates also includes TPX-0022, targeting MET, CSF1R and SRC, which is being studied in a Phase 1 trial of patients with advanced or metastatic solid tumors harboring genetic alterations in MET; TPX-0046, targeting RET, which is being studied in a Phase 1/2 trial of patients with advanced or metastatic solid tumors harboring genetic alterations in RET; and TPX-0131, a next-generation ALK inhibitor, which is being studied in a Phase 1/2 trial of previously treated patients with ALK-positive advanced or metastatic non-small cell lung cancer. Turning Point’s next-generation kinase inhibitors are designed to bind to their targets with greater precision and affinity than existing therapies, with a novel, compact structure that has demonstrated an ability to potentially overcome treatment resistance common with other kinase inhibitors. The company is driven to develop therapies that mark a turning point for patients in their cancer treatment. For more information, visit www.tptherapeutics.com.
