A Clinical Study of Bemcentinib With Standard of Care Chemoimmunotherapy in Untreated Advanced/Metastatic Non-small Cell Lung Cancer Patients With a Mutation in the STK11 Gene

Phase 1b/2a Safety and Tolerability Study of Bemcentinib With Pembrolizumab/Carboplatin/Pemetrexed in Subjects With Untreated Advanced or Metastatic Non-squamous Non-small Cell Lung Cancer (NSCLC) Without/With a STK11 Mutation

The primary purpose of this study is to determine the safety and tolerability of the combination of bemcentinib with chemo-immunotherapy (CIT) to identify the recommended phase 2 dose (RP2D) when administered as first line (1L) treatment in participants with locally advanced (Stage IIIb/IIIC) or metastatic (Stage IV) non-squamous NSCLC with no actionable mutations and to determine the anti-tumor activity of the combination of bemcentinib with CIT when administered as 1L treatment in participants with locally advanced (Stage IIIb/IIIc) or metastatic (Stage IV) non-squamous NSCLC with serine/threonine kinase 11 (STK11) mutation and no actionable mutations.

Main Inclusion Criteria:

• Histologically-confirmed or cytologically confirmed diagnosis of advanced (Stage IIIb/IIIc) or metastatic (Stage IV) (AJCC Edition 8) non-squamous NSCLC not amenable to curative therapy, irrespective of PD-L1 status and without actionable mutations (Phase 1b) targetable with first-line treatment.
• Histologically-confirmed or cytologically confirmed diagnosis of stage of advanced (Stage IIIb/IIIC) or metastatic (Stage IV) (AJCC, Edition 8) non-squamous NSCLC with STK11 mutation, not amenable to curative therapy, irrespective of PD-L1 status and without actionable mutations (phase 2a) targetable with first-line treatment.
• Have not received prior systemic treatment for their advanced/metastatic NSCLC
• Have measurable disease per RECIST 1.1 as assessed by the investigator

Main Exclusion Criteria:

• Has received any prior chemotherapy or biological therapy for locally advanced (Stage IIIb/IIIc) or metastatic (Stage IV) adenocarcinoma of the lung
• Received radiation therapy within 2 weeks prior to starting study treatment or has not recovered (i.e. <=Grade 1 at baseline) from AEs due to a previous radiation therapy
• Major surgery within 28 days prior to start of study treatment and failure to have recovered adequately from the complications of the surgery/intervention prior to the first dose of study treatment
