Isunakinra Alone and in Combination With Pembrolizumab in Patients With Colorectal Cancer (MSS)
What this study is about
This study will enroll patients with colorectal cancer that is locally advanced or metastatic. The tumor must be microsatellite stable (MSS), have a tumor mutational burden that is high (TMB-H) and be kras mutated. Patients must have been treated with available approved treatments already.

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
- 1\. Subjects must have:
- Histologically or cytologically confirmed adenocarcinoma of the colon or the rectum
- Tumor is determined to be RAS-mutated (KRAS, NRAS or HRAS) and microsatellite stable/proficient in mismatch repair, as assessed by immunohistochemistry (IHC) and/or polymerase chain reaction (PCR)/next generation sequencing (NGS) in a Clinical Laboratory Improvement Act (CLIA) environment and with a tumor mutational burden (TMB) of 10 MB or more. 2\. The study patients are required to have measurable disease by radiographic criteria (RECIST 1.1 and iRECIST). 3\. Prior therapy: Patients must have completed or had disease progression on at least one prior line of disease-appropriate therapy for metastatic disease (with or without PD-1 inhibitors), with no available therapy likely to convey clinical benefit, or not be candidates for therapy of proven efficacy for their disease. 4\. There should be a minimum of 4 weeks from any

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.
