Brief Summary:
The purpose of this study is to evaluate the safety and tolerability, pharmacokinetics (PK) pharmacodynamics and preliminary antitumor activity of vobramitamab duocarmazine (MGC018) in patients with advanced solid tumors.

Condition or disease Intervention/treatment Phase
Squamous Cell Carcinoma of Head and Neck Triple Negative Breast Cancer Melanoma Advanced Solid Tumor, Adult Metastatic Castrate Resistant Prostate Cancer Non Small Cell Lung Cancer Biological: vobramitamab duocarmazine Biological: retifanlimab Phase 1 Phase 2

Detailed Description:

This Phase 1/2 study will characterize safety, dose-limiting toxicities (DLTs), and maximum tolerated/administered dose (MTD/MAD) and anti-tumor activity for vobramitamab duocarmazine as monotherapy (Module A) in patients with advanced solid tumors. 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), triple-negative breast cancer (TNBC), squamous cell carcinoma of the head and neck (SCCHN), and melanoma. 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, vobramitamab duocarmazine in combination with retifanlimab will not enroll.
