Brief Summary

This is a Phase 1/2, open-label first-in-human study of the safety, pharmacokinetics (PK), pharmacodynamics, and anti-tumor activity of BLU-451 monotherapy and BLU-451 in combination with platinum-based chemotherapy (carboplatin and pemetrexed). All participants will receive BLU-451 on a 21-day treatment cycle.

Detailed Description

The study is a Phase 1/2 Study of BLU-451 in Advanced Cancers with Epidermal growth factor receptor (EGFR) Exon 20 Insertion Mutations (Ex20ins). The study has two phases:

An initial Phase 1 portion will enroll participants with metastatic cancer with EGFR Ex20ins or other selected EGFR mutations that have progressed after prior systemic therapies and will determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of BLU-451.

Part 1B dose-escalation will enroll participants with metastatic Non-small Cell Lung Cancer (NSCLC) in the USA only to determine the MTD and/or RP2D of BLU-451 in combination with carboplatin and pemetrexed.

A Phase 2 portion will further evaluate the efficacy and safety of BLU-451 as monotherapy at RP2D in participants with NSCLC.

Phase I - Part 1A Dose EscalationBLU-451BLU-451 monotherapy with dose escalation in participants with metastatic cancer with EGFR Ex20ins or other selected EGFR mutations that have progressed after prior systemic therapies.
Phase I - Part 1B Dose Escalation (US only)CarboplatinBLU-451 with dose escalation in combination with carboplatin and pemetrexed in participants with metastatic NSCLC with common EGFR mutations. This arm will enroll participants only in the United States.
Phase I - Part 1B Dose Escalation (US only)PemetrexedBLU-451 with dose escalation in combination with carboplatin and pemetrexed in participants with metastatic NSCLC with common EGFR mutations. This arm will enroll participants only in the United States.
Phase II - Cohort 2ABLU-451EGFR Ex20ins participants who have previously received platinum-based chemotherapy and either amivantamab or mobocertinib will receive BLU-451.

Phase I - Part 1B Dose Escalation (US only)BLU-451BLU-451 with dose escalation in combination with carboplatin and pemetrexed in participants with metastatic NSCLC with common EGFR mutations. This arm will enroll participants only in the United States.
Phase II - Cohort 2DBLU-451Participants with EGFR Ex20ins who have previously received platinum-based chemotherapy and both amivantamab AND mobocertinib, OR received any investigational Ex20Ins targeted agent(s) will receive BLU-451. Participants with Ex20ins or atypical mutations enrolled in other cohorts and who have other oncogenic drivers by central testing at baseline will be moved to this arm.
Phase II - Cohort 2BBLU-451EGFR Ex20ins participants who have previously received platinum-based chemotherapy but have not received a prior EGFR Ex20ins-targeted agent will receive BLU-451.
Phase II - Cohort 2CBLU-451EGFR Ex20ins participants with at least one measurable lesion in brain per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 who have previously received platinum-based chemotherapy will receive BLU-451. Previous treatment with EGFR Ex20Ins-targeted therapies is allowed but not required.
Phase II - Cohort 2EBLU-451Participants with EGFR Ex20ins who have not received prior systemic therapy in metastatic setting will receive BLU-451.
Phase II - Cohort 2FBLU-451Participants with EGFR atypical mutations (e.g., G719X, L861Q) who have previously received at least one EGFR tyrosine kinase inhibitor (TKI) will receive BLU-451. Participants with with other atypical EGFR mutations, such as S768I, may be enrolled if approved by Sponsor Medical Monitor.
Phase II - Cohort 2GBLU-451Participants with EGFR atypical mutations (e.g., G719X, L861Q) who have not received prior systemic therapy in metastatic setting will receive BLU-451. Participants with with other atypical EGFR mutations, such as S768I, may be enrolled if approved by Sponsor Medical Monitor.
