Phase 2 Study of Study of Tesevatinib in Subjects With NSCLC and Brain or Leptomeningeal Metastases

Non-Small Cell Lung Cancer Clinical Trial

Official title: A Phase 2, Multicenter Study of Tesevatinib in Subjects With Non-Small Cell Lung Cancer, EGFR Activating Mutation, Prior Treatment With a Tyrosine Kinase Inhibitor, and Brain Metastases or Leptomeningeal Metastases

Status Completed

Clinical Trial Summary

A study to assess the activity of tesevatinib in subjects with non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations who have disease progression with Brain Metastases (BM) or Leptomeningeal Metastases (LM) or who have either BM or LM at initial presentation (IP)

Clinical Trial Description

This was a multicenter, phase 2, open-label study to assess the activity of tesevatinib, in subjects with non-small cell lung cancer (NSCLC) and activating epidermal growth factor receptor (EGFR) mutations, and brain metastases (BM) or leptomeningeal metastases (LM). After completion of the screening assessments and confirmation of study eligibility, tesevatinib was orally administered to all subjects at a dose of 300 mg once daily (QD). Tumor response, both in the central nervous system (CNS) and outside the central nervous system (non-CNS), was assessed after the second cycle of treatment and then at the end of every two cycles of treatment thereafter. Subjects were treated with tesevatinib 300 mg QD until disease progression or the subject experienced unacceptable toxicity. Subjects who discontinued tesevatinib therapy were followed for survival. Subjects with NSCLC + EGFR mutations were assigned to one of three cohorts: - Cohort A: Brain Metastases (BM). Subjects had progressed with BM. - Cohort B: Leptomeningeal Metastases (LM). Subjects had initially presented or progressed with LM. - Cohort C: Brain Metastases at Initial Presentation (BM-IP). Subjects had no prior systemic therapy. Each of the three cohorts was to have 20 subjects, for a total of 60 subjects. All three cohorts were enrolled simultaneously. The primary objectives were to include: - Clinical activity of tesevatinib of subjects in Cohort A (BM) and Cohort C (BM-IP) as measured by Response Criteria in Solid Tumors (RECIST) version 1.1 which evaluated changes in BM size. - Clinical activity of tesevatinib of subjects in Cohort B (LM) as measured by improvement in Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 symptoms and signs. Efficacy assessments included response to treatment using RECIST criteria, progression-free survival (PFS), time to progression (TTP), overall survival (OS), and Quality of Life (QOL) questionnaires. Safety assessments included adverse event (AE) monitoring, electrocardiogram (ECG), Eastern Cooperative Oncology Group (ECOG) Performance Status, laboratory testing, physical examination, vital signs, and pregnancy testing. In addition, pharmacokinetic (PK) and pharmacodynamic (PD) assessments were performed. An End of Treatment Visit occurred within 3 days after the subject's last dose of study drug. This could have occurred at the visit when disease progression was diagnosed. Subjects were continued to be followed for disease progression and survival. A follow-up visit occurred 30 days (± 5 days) after the last dose of study drug. This visit may have occurred prior to 30 days if a new therapy was started within 30 days of last dose of study drug. For long-term follow-up, after subjects withdrew from the active treatment portion of the study, they were contacted by telephone every 8 weeks to assess survival status and any subsequent anti-cancer treatment. ;
