Brief Summary:
The main purpose of the study is to evaluate safety and efficacy of taletrectinib (also known as AB-106 or DS-6051b) monotherapy in the treatment of advanced NSCLC.

Condition or disease Intervention/treatment Phase
Non Small Cell Lung Cancer Drug: Taletrectinib Phase 2

Detailed Description:

This is a global Phase 2, multicenter, single-arm, open label study of taletrectinib in patients of NSCLC harboring with ROS1 fusion gene.

About 224 patients will be enrolled and divided into 6 cohorts, depending on past history of ROS1 TKI treatment.

In the cohorts open to enrollment, taletrectinib will be administered either 400mg or 600mg once daily in 21-day cycles. In one cohort, this will be in combination with carboplatin and pemetrexed both administered by IV infusion in 21-day cycles for 4 cycles. Patients will continue with the treatment on taletrectinib until progression of disease as determined by the investigator.

The tumor response evaluation will be conducted on a regular basis until progression of disease. Long-term survival follow up will be conducted as well.

  4. Patients with central nervous system (CNS) involvement, including leptomeningeal carcinomatosis, must be stable, either asymptomatic or previously treated and controlled within 14 days of first dose.
  5. The patient can be either ROS1 TKI treatment naïve or treated with prior ROS1 TKI(s).
  6. The patient must have at least 1 measurable disease per RECIST 1.1 as assessed by the investigator.
  7. Eastern Cooperative Oncology Group Performance Status: 0 or 1.
  8. Patient with a life expectancy ≥12 weeks based on the judgement of investigator.
  9. Patients with adequate organ function meeting the following criteria:

    1. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT): ≤3.0 × upper limit of normal (ULN) (or ≤5.0 × ULN, for patients with concurrent liver metastases)
    2. Serum total bilirubin: ≤1.5 × ULN (≤3.0 × ULN for patients with Gilbert syndrome or if liver function abnormalities are due to underlying malignancy)
