Global, Phase 3, randomized, multicenter, open-label study evaluating the efficacy and safety of furmonertinib (firmonertinib) at 2 dose levels (160 mg once daily [QD] and 240 mg QD) compared to platinum-based chemotherapy in previously untreated patients with locally advanced or metastatic non-squamous Non-Small Cell Lung Cancer (NSCLC) with Epidermal Growth Factor Receptor (EGFR) exon 20 insertion mutations. A target of approximately 375 patients will be randomized in a 1:1:1 ratio to treatment with furmonertinib 240 mg QD, furmonertinib 160 mg QD, or platinum-based chemotherapy.

Key Inclusion Criteria:

• Histologically or cytologically documented, locally advanced or metastatic non-squamous Non-Small Cell Lung Cancer (NSCLC) not amenable to curative surgery or radiotherapy.
• Documented results of the presence of an Epidermal Growth Factor Receptor (EGFR) exon 20 insertion mutation in tumor tissue or blood from local or central testing.
• No prior systemic anticancer therapy regimens received for locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) including prior treatment with any Epidermal Growth Factor Receptor (EGFR)-targeting agents (e.g., previous (EGFR) TKIs, monoclonal antibodies, or bispecific antibodies).
• Patients who have received prior neo-adjuvant and/or adjuvant chemotherapy, immunotherapy, or chemo radiotherapy for non-metastatic disease (excluding EGFR-TKIs) must have experienced a treatment free interval of at least 12 months.
• Patients with a history of treated CNS metastases or new asymptomatic CNS metastases are eligible.
