Interventions

  • Zorifertinib and Osimertinib Combination Therapy — DRUG
    Zorifertinib is an oral tablet (50 mg or 100 mg). Osimertinib is an oral tablet (80 mg). In this Phase 1 study, all participants will receive the combination. Osimertinib is given at a fixed dose of 80 mg once daily. Zorifertinib is given twice daily, with dose levels under evaluation (starting at 100 mg BID, potentially escalating to 150 mg BID, 200 mg BID, or higher). Dose escalation follows a "3+3" design based on dose-limiting toxicity (DLT) assessment in the first 21-day cycle. Treatment continues until disease progression, unacceptable toxicity, or meeting other discontinuation criteria.

Study Details

This is a clinical trial that aims to test Zorifertinib when used together with a known drug, Osimertinib. The goal is to learn if this combination is safe and works for people with advanced Non-Small Cell Lung Cancer (NSCLC) whose cancer has spread to the membranes surrounding the brain and spinal cord (a condition called leptomeningeal metastases) after being treated with Osimertinib.

Arms

  • Experimental: Zorifertinib + Osimertinib (Dose Escalation)
    All enrolled participants will receive the investigational combination therapy of Zorifertinib and Osimertinib. This is a Phase 1 study consisting of a dose escalation part (Part A) and a dose expansion part (Part B). In Part A, Zorifertinib dose will be escalated (starting at 100 mg twice daily) alongside a fixed dose of Osimertinib (80 mg once daily) using a "3+3" design to determine the recommended dose. In Part B, additional participants will receive the combination at the recommended dose to further evaluate safety, efficacy, and pharmacokinetics. Treatment continues until disease progression, unacceptable toxicity, or meeting other discontinuation criteria.

Primary Outcome Measure

Determination of Recommended Dose Based on Incidence of Dose-Limiting Toxicities (DLTs) [ Time Frame: During the first 21 days of continuous administration for each participant in the dose-escalation phase. ]
