This study will treat patients with advanced NSCLC with EGFR or HER2 mutation who have progressed following prior therapy. This is the first time this drug is tested in patients, and so it will help to understand what type of side effects may occur with the drug treatment. It will also measure the levels of drug in the body and preliminarily assess its anti-cancer activity as monotherapy.
Description: To investigate the safety and tolerability of DZD9008 when given orally to patients with advanced NSCLC with EGFR or HER2 mutations; To establish Maximum Tolerated Dose (MTD) (if possible) and Recommended Phase 2 Dose (PR2D) of DZD9008 when given orally in patients with advanced NSCLC with EGFR or HER2 mutations.Measure: Part A: Safety and tolerability of DZD9008. Time: 28 days after the first multiple dose
Description: To evaluate anti-tumor activity of DZD9008 in advanced NSCLC patients with EGFR Exon20 insertion, HER2 Exon20 insertion or EGFR uncommon mutations at defined dose(s) (Part B)Measure: Part B: Objective Response Rate (ORR) according to RECIST 1.1. Time: through the study completion, an average of around 1 year
Description: To characterize the pharmacokinetics (PK) of DZD9008 following a single oral dosing and at steady state after multiple oral dosing, and renal excretion of DZD9008Measure: Plasma DZD9008 concentration Time: Through cycle 3 day 1 (8 days for Cycle 0, 28 days for Cycle 1, then 21 days for each subsequent cycle)
