Brief summary

This is a Phase 1 study of BBP-398, a SHP2 inhibitor, in combination with nivolumab, a PD-1 antibody, in patients with NSCLC with a KRAS mutation. The study involves 2 parts: Phase 1a Dose Escalation and Phase 1b Dose Expansion.

Detailed description

The primary objective for Phase 1a Dose Escalation is to evaluate the safety, tolerability, and RP2D of BBP-398, a SHP2 inhibitor, when used in combination with nivolumab in patients with advanced NSCLC with a KRAS mutation who have failed standard of care treatment. The primary objective for Phase 1b Dose Expansion is to evaluate the antitumor activity of BBP-398, as defined by the ORR (per investigator) according to RECIST v1.1, when used in combination with nivolumab in patients with advanced NSCLC with a KRAS mutation who have failed standard of care treatment.

Inclusion criteria

Key Inclusion Criteria: * Patients must have histologically documented, locally advanced and unresectable, or metastatic NSCLC with documentation of a KRAS mutation within the 1 year prior to screening. * Patients must have measurable disease by RECIST v1.1. * Patients must have a minimum life expectancy of \>12 weeks after start of study treatment. * Patients must have progression or disease recurrence on or after at least one prior line of systemic therapy, which must include platinum-based doublet chemotherapy and anti-PD-(L)1 therapy. * Patients must have experienced progressive or recurrent disease occurring either during treatment or within 90 days after discontinuing anti-PD-(L)1 therapy. * Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1. * Patients must have adequate organ function. Key

Exclusion criteria

* Patients that have participated in an interventional clinical study within the last 4 weeks. * Patients that have received radiotherapy or proton therapy with a limited field of radiation for palliation within 1 week of the start of study treatment, OR radiation to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the start of study treatment. * Patients with known central nervous system (CNS) tumors or active CNS metastases. * Patients that have experienced progressive disease (PD) within the first 120 days of initiating treatment with an anti- PD-(L)1 agent (e.g., primary refractory). * Patients that have a history of allogenic bone marrow transplant. * Patients that have select known or suspected autoimmune disease. * Patients that have a condition requiring systemic treatment with either corticosteroids (\>10 mg prednisone equivalent) or other immunosuppressive medication within 14 days of study start. * Patients that have received any live/attenuated vaccine within 30 days of first study treatment.

Design outcomes

Primary

MeasureTime frameDescription
Phase 1a Dose Escalation: Assess safety, tolerability, and recommended phase 2 dose (RP2D) of BBP-398 in combination with nivolumabCompletion of 1 Cycle (28 days)
Phase 1b Dose Expansion: Assess antitumor activity of BBP-398 in combination with nivolumabCompletion of 1 Cycle (28 days)Anti-tumor activity will be defined by objective response rate (ORR) according to RECIST v1.1

Secondary

MeasureTime frameDescription
Assess preliminary antitumor activity of BBP-398 in combination with nivolumabCompletion of 1 Cycle (28 days)Anti-tumor activity will be defined by objective response rate (ORR) \[escalation\], duration of response (DOR) and progression free survival (PFS), as defined by RECIST v1.1. and overall survival (OS) \[both escalation and expansion\]
Phase 1b Dose Expansion: Assess safety and tolerability of BBP-398 at the RP2D, in combination with nivolumabCompletion of 1 Cycle (28 days)
