What it is measuring
Recommended phase 2 dose (RP2D) of pidnarulex (CX-5461) with anti-programmed cell death protein 1 (anti-PD-1) (Phase 1)
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
What this trial is trying to do
The researchers are testing whether pidnarulex, which may block enzymes involved in tumour-cell growth and damage tumour DNA, can be combined with cemiplimab, an immune treatment that blocks PD-1 (a protein that can restrain immune attacks). The idea is that the drug combination might make treatment-resistant, microsatellite-stable colorectal cancer more vulnerable to the immune system.
The trial will first establish a tolerable dose and then assess whether the combination controls cancer that has stopped responding to previous treatment. Improvement would mean acceptable side effects and longer periods before the cancer grows, although the listed early outcome is dose and safety rather than survival.
Worth knowing: This is a phase I/II trial, so its early part is mainly testing safety and dose; it has no stated comparison group.
Written from the trial's own registry entry to explain what the researchers are testing and why. Nothing here is a result — this trial has not reported one — and it is not a view on whether the treatment works or on whether it would suit you.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
This phase I/II trial studies the side effects and best dose of pidnarulex when given together with cemiplimab and to see how well it works in treating patients with microsatellite stable (MSS) colorectal cancer (CRC) that does not respond to treatment (refractory). Pidnarulex may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving pidnarulex with cemiplimab may be safe, tolerable and/or effective in treating patients with refractory MSS CRC.

Who the trial is looking for
Inclusion Criteria
- Patients must have pathologically confirmed colorectal adenocarcinoma that is unresectable and/or metastatic and for which standard curative or palliative measures do not exist or are no longer effective
- Patients must have measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1
- Patients must have pathologically confirmed proficient mismatch repair proteins (pMMR) and/or not microsatellite-high status (non-MSI-H). This may be confirmed by local tissue testing of the primary tumor and/or any metastatic lesion utilizing approved immunohistochemistry (for mismatch repair status) and/or polymerase chain reaction or next generation sequencing (for microsatellite status) assays. Historical (i.e., previously obtained) biopsy mismatch repair (MMR) and microsatellite instability (MSI) status may be utilized. If historical tissue is available, MMR and/or MSI testing may be performed on that tissue if not done previously. Clinical documentation of the patient's MMR and/or MSI status in the medical record may also be utilized to determine MMR and/or MSI status for the purposes of eligibility.

Where it is running
Running at 6 sites. Listed in: United States.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
