A Phase 1 Study of JNJ-78306358, a T Cell Redirecting Bispecific Antibody Targeting HLA-G for Advanced Stage Solid Tumors

Study start date: October 24, 2021

Inclusion Criteria * Histologically or cytologically confirmed, metastatic or unresectable solid tumor of one of the following types: a. Renal Cell Carcinoma (RCC): clear cell or papillary carcinoma, b. ovarian cancer: high grade serous epithelial ovarian; primary peritoneal or fallopian tube cancer; 1. low grade or non-serous histologies are not allowed; c. colorectal cancer (CRC); d. other tumor types (including lung adenocarcinoma, endometrial cancer, and pancreas cancer) may be enrolled with sponsor approval * Measurable or evaluable disease: a. Part 1: either measurable or evaluable disease; b. Part 2: at least one measurable lesion per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. Participants with ovarian cancer without a measurable lesion must have disease evaluable per RECIST version1.1 (example ascites) or have Cancer antigen 125 (CA 125) greater than (\>) 2\*upper limit of normal (ULN) within 2 weeks prior to first dose of study drug * Progressed during or after the following prior therapies for metastatic disease, unless participant was ineligible to receive them: a) RCC: clear cell histology: an antiangiogenic agent and an immune checkpoint inhibitor, administered as 1 or more lines of therapy. For papillary renal carcinoma 1 line of systemic therapy; b. CRC: at least 2 lines of therapy including a fluoropyrimidine, oxaliplatin, and irinotecan given with or without antiangiogenic therapies or epidermal growth factor receptor (EGFR) antibodies. In addition, prior treatment with anti-programmed cell death protein 1 (PD1) antibody is required for high microsatellite instability (MSI-H) CRC; c. ovarian cancer: at least 2 lines of therapy, including at least 1 line with platinum. Maintenance therapy after completion of platinum-containing regimen, example with bevacizumab or a poly- Adenosine di-phosphate (ADP) ribose polymerase inhibitor will not count as a separate line of therapy; d. other tumor types: at least 2 lines of systemic therapy * Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1 * Selected participants in pharmacokinetics/pharmacodynamic (PK/PD) cohorts and in Part 2 must agree to undergo the mandatory tumor biopsies Exclusion Criteria: * Active central nervous system involvement * Toxicity from prior anticancer therapy has not resolved to baseline levels or to Grade less than or equal to (\<=) 1 (except alopecia, vitiligo, peripheral neuropathy, or endocrinopathies that are stable on hormone replacement, which may be Grade 2) * Clinically significant pulmonary compromise * Autoimmune or inflammatory disease requiring systemic steroids or other immunosuppressive agents (example, methotrexate or tacrolimus) within 1 year prior to first dose of study drug * Solid organ or bone marrow transplantation
