Conditions

Carcinoma, Non-Small-Cell Lung

Brief summary

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.

Interventions

Bemcentinib capsules will be administered daily orally.

DRUGPembrolizumab

Pembrolizumab will be administered as an intravenous (IV) infusion as part of CIT every 3 weeks.

DRUGPemetrexed

Pemetrexed will be administered as an IV infusion as part of CIT every 3 weeks.

DRUGCarboplatin

Carboplatin will be administered as an IV infusion as part of CIT every 3 weeks up to 4 cycles. Each cycle = 21 days.

Inclusion criteria

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

The following assessments were performed: Informed Consent, Demographics, Medical/Surgical History including NSCLC diagnosis and prior anticancer treatments, Pregnancy/FSH, ECOG performance score, Vital signs, Physical examination, Echocardiogram, Laboratory Safety Testing, ECG, Tumour imaging/sampling and biopsies & blood sampling for genomic DNA/serum biomarkers.

Participants by arm

ArmCount
Phase 1b Cohort 1: Bemcentinib 75 mg
Participants with previously untreated locally advanced (Stage IIIb/IIIc)/metastatic (Stage IV) non-squamous NSCLC without actionable mutations received oral bemcentinib 75 mg once daily until a reason for discontinuation had been met or for up to 2 years, whichever occurred first along with CIT (pembrolizumab infusion followed by pemetrexed and carboplatin). CIT was administered on day 1 of 21-day cycles via intravenous (IV) infusions and comprised pembrolizumab, pemetrexed, and carboplatin. Carboplatin was administered for a maximum of 4 cycles only.
3
Phase 1b Cohort 2: Bemcentinib 100 mg
Participants with previously untreated locally advanced (Stage IIIb/IIIc)/metastatic (Stage IV) non-squamous NSCLC without actionable mutations received oral bemcentinib 100 mg once daily until a reason for discontinuation had been met or for up to 2 years, whichever occurred first along with CIT (pembrolizumab infusion followed by pemetrexed and carboplatin). CIT was administered on day 1 of 21-day cycles via intravenous (IV) infusions and comprised pembrolizumab, pemetrexed, and carboplatin. Carboplatin was administered for a maximum of 4 cycles only.
3
Phase 1b Cohort 3: Bemcentinib 150 mg
Participants with previously untreated locally advanced (Stage IIIb/IIIc)/metastatic (Stage IV) non-squamous NSCLC without actionable mutations received oral bemcentinib 150 mg once daily until a reason for discontinuation had been met or for up to 2 years, whichever occurred first along with CIT (pembrolizumab infusion followed by pemetrexed and carboplatin). CIT was administered on day 1 of 21-day cycles via intravenous (IV) infusions and comprised pembrolizumab, pemetrexed, and carboplatin. Carboplatin was administered for a maximum of 4 cycles only.
4
Phase 2a Expansion Cohort: Bemcentinib 100 mg (as the Dose Determined From Phase 1b)
Participants with previously untreated advanced (Stage IIIb/IIIc)/metastatic (Stage IV) non-squamous NSCLC having a serine/threonine kinase 11 (STK11) mutation as identified by Next Generation Sequencing (NGS) and without actionable mutations will receive bemcentinib, at RP2D identified in Phase 1b, once daily until a reason for discontinuation has been met or for up to 2 years, whichever occurs first along with CIT (pembrolizumab infusion followed by pemetrexed and carboplatin). CIT was administered on day 1 of 21-day cycles via intravenous (IV) infusions and comprised pembrolizumab, pemetrexed, and carboplatin. Carboplatin was administered for a maximum of 4 cycles only.
