FURMO-002: A Phase 1b Dose Escalation and Dose Expansion Study Evaluating the Safety, Pharmacokinetics, and Antitumor Activity of Furmonertinib in Patients with Advanced or Metastatic Non-Small Cell Lung Cancer (NSCLC) with Activating EGFR or HER2 Mutations, Including Exon 20 Insertion Mutations

The purpose of this study is to learn about how the study drug, furmonertinib, works in patients with NSCLC who have a mutation in the EGFR or HER2 gene and how it may help them. For patients with this type of NSCLC, the study will help researchers to learn how safe the study drug is, to learn how much of the study drug to give to patients, and to compare the effects, good or bad, of the study drug.
