Turning Point Therapeutics Initiates Global Phase 1/2 Forge-1 Clinical Study of TPX-0131, a Next-Generation ALK Inhibitor
Investigational New Drug Application Cleared
Study Initiated in
The investigational new drug (IND) application for TPX-0131 is Turning Point’s third IND to be cleared by the FDA in less than 2 years, and FORGE-1 is the company’s fourth clinical study to initiate during the same period of time.
The study was initiated in
“With a lack of available therapies to address a broad spectrum of ALK resistant mutations, we are encouraged by the preclinical potency for TPX-0131, particularly against the G1202R solvent front mutation which is reported to occur in more than 40% of biopsies with resistance mutations,” said
ALK alterations are estimated to be responsible for 3% to 5% of non-small cell lung cancer (NSCLC) cases annually in the
“Our clinical study of TPX-0131 will begin with a Phase 1 dose finding portion in patients previously treated with up to 2 prior ALK tyrosine kinase inhibitors, a population we believe is underserved today by available therapies that are less potent against known resistant mutations of ALK,” said
The Phase 1 dose finding portion of the FORGE-1 study will enroll patients with locally advanced or metastatic TKI-pretreated ALK-positive NSCLC. Patients with up to 2 prior ALK TKIs and 1 prior platinum-based chemotherapy will be enrolled. The study endpoints include safety and tolerability, determination of the maximum tolerated dose and/or the recommended Phase 2 dose, and objective response rate by RECIST 1.1.
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.
