Brief summary

The purpose of this study is to determine the recommended phase 2 dose (RP2D) regimen(s) of JNJ-78306358 in Part 1 (Dose Escalation) and to determine the safety of JNJ-78306358 at the RP2D regimen(s) in Part 2 (Dose Expansion).

Detailed description

JNJ-78306358 is a bispecific antibody binding to CD3 on T cells and human leukocyte antigen G (HLA-G) on cancer cells. The study consists of a screening phase, a treatment phase, and a post-treatment follow-up phase. Study evaluations include safety, pharmacokinetics, biomarkers, immunogenicity, and efficacy (disease evaluations). The total study duration will be up to 2 years 4 months.

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

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants with Incidence of Adverse Events (AEs)Up to 2 years and 4 monthsAn AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
Number of Participants with AEs by SeverityUp to 2 years and 4 monthsNumber of participants with AEs by severity will be reported. Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0 with the exception of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) events, which will be graded according to the American Society for Transplantation and Cellular Therapy (ASTCT) guidelines. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death related to adverse event.
Part 1: Number of Participants with Dose-limiting Toxicity (DLT)Up to 21 daysNumber of participants with DLT will be assessed. The DLTs are specific adverse events and are defined as any of the following: high grade non-hematologic toxicity, or hematologic toxicity.

Secondary

MeasureTime frameDescription
Area Under the Serum Concentration-time Curve From Time t1 to t2 (AUC[t1-t2]) of JNJ-78306358Up to 2 years and 4 monthsAUC(t1-t2) is defined as the area under the serum concentration-time curve from time t1 to t2.
Accumulation Ratio (RA) of JNJ-78306358Up to 2 years and 4 monthsRA is calculated as area under the plasma concentration-time curve from time zero to 24 hours (AUC \[0-24\]) value at steady state divided by AUC (0-24) value after first dose.
Overall Response Rate (ORR)Up to 2 years and 4 monthsORR is defined as the percentage of participants who achieve complete response (CR) or partial response (PR), according to response evaluation criteria in solid tumors (RECIST) version 1.1 and gynecological cancer inter group (GCIG) Cancer antigen 125 (CA 125) response criteria (for ovarian cancer participants only).
Duration of Response (DOR)Up to 2 years and 4 monthsDuration of response (DOR) will be calculated among responders (PR or better) from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the RECIST version 1.1 response criteria and GCIG CA 125 response criteria (for ovarian cancer participants only) or death due to any cause, whichever occurs first.
Number of Participants with Anti-JNJ-78306358 AntibodiesUp to 2 years and 4 monthsNumber of participants with anti-JNJ-78306358 antibodies will be reported.
Maximum Serum Concentration (Cmax) of JNJ-78306358Up to 2 years and 4 monthsCmax is defined as maximum serum concentration of JNJ-78306358.
Time to Reach Maximum Observed Serum Concentration (Tmax) of JNJ-78306358Up to 2 years and 4 monthsTmax is defined as time to reach maximum observed serum concentration of JNJ-78306358.
