About this trial
The investigational drug to be studied in this protocol, BCA101, is a first-in-class compound that targets both EGFR with TGFβ. Based on preclinical data, this bifunctional antibody may exert synergistic activity in patients with EGFR-driven tumors.
Eligibility criteria
Qualifiers
Patient must have measurable disease amendable to biopsy and be willing to undergo both a pre-treatment and on-treatment biopsy, as well as provide archival tumor if available from the primary tumor (a paraffin embedded tumor tissue block sufficient to obtain at least 10 sections of 4 to 5 micrometer thickness).
Patient must have a performance status of ≤1 on the Eastern Cooperative Oncology Group Performance Scale.
Patients must have evaluable or measurable disease (computed tomography [CT]/magnetic resonance imaging [MRI] scans performed within 21 days before the screening visit are acceptable) demonstrating measurable disease, i.e., at least 1 unidimensional measurable lesion as defined by Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST 1.1) and Immune Response Evaluation Criteria in Solid Tumors (iRECIST).
Expansion Cohort 3: Squamous Carcinoma of the Anal Canal (SCAC), locally advanced/unresectable or metastatic.
Disqualifiers
For Part A: Exposure to anti-EGFR antibodies within 4 weeks of the first dose of study drug.
Prior treatment with any anti-TGFβ therapy.
Prior history of Grade ≥ 2 intolerance or hypersensitivity reaction to cetuximab or other anti-EGFR therapy or other murine proteins or prior discontinuation of therapy in the setting of toxicity related to treatment.
Pregnant or breastfeeding women.
