A Study of JNJ-1761981 in Participants With Solid Tumors
What this study is about
The purpose of Part 1 of this study is to determine a safe, tolerable, and feasible recommended total dose of intratumorally administered JNJ-1761981. The purpose of Part 2 of this study is to identify the optimal volumetric dose of JNJ-1761981 for the treatment of tumor lesions.

The purpose of Part 1 of this study is to determine a safe, tolerable, and feasible recommended total dose of intratumorally administered JNJ-1761981. The purpose of Part 2 of this study is to identify the optimal volumetric dose of JNJ-1761981 for the treatment of tumor lesions.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Part 1: Individuals with a diagnosis of locally advanced or metastatic disease (solid tumors except tumors of the central nervous system \[CNS\]) who have previously received available standard therapy and progressed, or cannot tolerate standard therapy, or for whom there is no standard of care per regional guidelines
- Part 2 Cohort A: Individuals with histologically or cytologically confirmed metastatic tumors of adenocarcinoma or squamous cell carcinoma histology, for which any platinum-based systemic regimen is considered a standard of care (per national comprehensive cancer network \[NCCN\] guidelines) and whose disease has progressed after standard therapy
- Eastern cooperative oncology group performance status (ECOG) performance status of Grade 0 or 1
- Part 2 Cohort A participants planned to receive optional cetrelimab (participants not meeting this criterion may still be enrolled in the study but cannot receive cetrelimab): Thyroid function laboratory values within normal range except for participants on thyroid hormone replacement therapy
- A participant of childbearing potential must practice at least 2 highly effective methods of contraception throughout the study and through 14 months (for women) and 11 months (for men) after the last dose of JNJ-1761981 or 5 months after the last dose of cetrelimab or other anti-PD(L)1 treatment, whichever is later
Exclusion criteria
- Active symptomatic disease involvement of the central nervous system
- Prior or concurrent second malignancy (other than the disease under study) that due to natural history or treatment is likely to interfere with any study endpoints of safety or the antitumor activity of the study treatment(s)
- Active bleeding diathesis or requirement for therapeutic anticoagulation that cannot be interrupted or altered for procedures
- Known allergies, hypersensitivity, or intolerance to JNJ-1761981 or its excipients
- Lesions invading or adjacent to major blood vessels or other critical structures (for example, airways) not suitable for injection
Where
- Jacksonville, Florida
- Rochester, Minnesota
- The Bronx, New York
- Houston, Texas
Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
