| NCT05256290 | Phase 1/2 Study of Silevertinib (BDTX-1535) in Patients With Glioblastoma or Non-Small Cell Lung Cancer With EGFR Mutations | PHASE1 | ACTIVE NOT_RECRUITING | 200 | — | — | Mar 31, 2022 | Jun 1, 2026 | Dec 9, 2025 | 25 | United States |
Dose-limiting toxicities (DLTs) in Cycle 1
Objective response rate (ORR) as assessed by Investigator using RECIST version 1.1
| Arm | Type | Description |
|---|---|---|
| Phase 1 Dose Escalation - Monotherapy (Recruitment Closed) | EXPERIMENTAL | * Advanced/metastatic NSCLC with acquired resistance EGFR mutation (eg, C797S), following a 3rd generation EGFR inhibitor in the 1st line setting (in the absence of concurrent T790M). * Advanced/metastatic NSCLC with non-classical EGFR mutation (eg, G719X) following standard-of-care therapy with an EGFR inhibitor * Recurrent GBM with confirmed EGFR alterations (including amplification, mutation, and/or variant) |
| Phase 2 Cohort 1: NSCLC EGFR Non-Classical Driver Mutations | EXPERIMENTAL | Advanced/metastatic NSCLC with a non-classical driver EGFR mutation following up to 2 lines of therapy with only 1 prior EGFR targeted regimen (third-generation preferred; other approved EGFR inhibitors acceptable) |
| Phase 2 Cohort 2: NSCLC EGFR Acquired Resistance (C797S) Mutation | EXPERIMENTAL | Advanced/metastatic NSCLC with the acquired resistance C797S EGFR mutation following up to 2 lines of therapy, including only 1 EGFR targeted regimen, which must be a third generation EGFR TKI (eg, osimertinib) |
| Phase 2 Cohort 3: Treatment Naive NSCLC EGFR Non-Classical Driver Mutations | EXPERIMENTAL | Treatment-naïve (first-line) advanced/metastatic NSCLC with a non-classical driver EGFR mutation (1 cycle of chemotherapy or immune checkpoint inhibitor are permitted). Patients with co-occurring L858R mutations and a non-classical mutation are eligible for inclusion. |

| silevertinib (BDTX-1535) monotherapy | DRUG | Silevertinib (BDTX-1535) is a 4th generation irreversible brain penetrant EGFR MasterKey inhibitor, which targets a family of oncogenic EGFR classical and non-classical driver and resistance mutations in NSCLC. |
Phase 2 Eligibility: Key Inclusion Criteria Required for locally advanced or metastatic NSCLC: * Measurable disease by RECIST 1.1 criteria. * Adequate bone marrow or organ function. * Life expectancy of ≥ 3 months. * Sufficient performance status. * Confirmed NSCLC, without small cell lung cancer ...
