Advanced Solid Tumor, Adult Metastatic Castrate Resistant Prostate Cancer Non Small Cell Lung Cancer Triple Negative Breast Cancer | Biological: MGC018 Biological: MGA012 | Phase 1 Phase 2 |
This Phase 1/2 study will characterize safety, dose-limiting toxicities (DLTs), and maximum tolerated/administered dose (MTD/MAD) and anti-tumor activity for MGC018 as monotherapy (Module A) in patients with advanced solid tumors. Each module consists of a Dose Escalation (3+3+3 design) followed by a Cohort Expansion Phase. Patients with solid tumors will be enrolled in the Dose Escalation Phase; Cohort Expansion will include metastatic castrate-resistant prostate cancer (mCRPC), non-small cell lung cancer (NSCLC), and triple-negative breast cancer (TNBC). Patients who do not experience unacceptable toxicity or meet criteria for permanent discontinuation may undergo additional cycles for up to two years. Patients in Cohort Expansion will be followed for survival every 3 months for 2 years following last dose.
Module B, MGC018 in combination with MGA012, Dose Escalation and Cohort Expansion will commence only upon sponsor notification to all study investigators.
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 150 participants |
Allocation: | Non-Randomized |
Intervention Model: | Sequential Assignment |
Intervention Model Description: | Dose escalation will use a 3+3+3 design to identify an MAD or MTD, followed by a Cohort Expansion. |
Masking: | None (Open Label) |
Primary Purpose: | Treatment |
Official Title: | A Phase 1/2, First-in-Human, Open-Label, Dose-Escalation Study of MGC018 (Anti-B7-H3 Antibody Drug Conjugate) Alone and in Combination With MGA012 (Anti-PD-1 Antibody) in Patients With Advanced Solid Tumors |
