What is being tested
- Drug RBS2418
- Drug Placebo
What it is measuring
Progression Free Survival
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 RBS2418, an ENPP1 inhibitor, can strengthen the immune response against colorectal cancer. By preventing breakdown of cGAMP, a chemical signal that activates antigen-presenting cells and then T cells, they expect it may help the immune system recognise and attack tumour cells better than placebo.
The trial asks whether adding RBS2418 can delay cancer growth compared with placebo, measured mainly by progression-free survival, while also assessing safety and immune responses. An improvement would mean longer before the cancer progresses, without unacceptable side effects.
Worth knowing: This is a placebo-controlled phase 2 trial, so its main outcome is time before progression rather than overall survival, and the treatment has not yet been shown to work.
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
RBS2418 is a specific immune modulator that works through the inhibition of ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) and is designed to lead to anti-tumor immunity by protecting endogenous 2'-3'-cyclic guanosine monophosphate-adenosine monophosphate (cGAMP) from hydrolysis and leading to the activation of antigen-presenting cells followed by T cell activation. The hypothesis is that RBS2418 versus placebo will be generally safe, well-tolerated, immunogenic, and will lead to anti-tumor responses in adult subjects for the treatment of advanced, metastatic, and progressive colorectal cancer (CRC).

Who the trial is looking for
Inclusion Criteria
1. At least 18 years of age on the day of signing informed consent.
2. Male and female subjects with advanced, metastatic, progressive CRC who have received, been ineligible for, intolerant to, or declined all approved standard of care (SOC) therapies for metastatic CRC, as per local SOC treatment regimens. Additionally, subjects must have documented PD based on two scans performed within 2 to 4 months of study initiation.
3. Have histologically or cytologically confirmed CRC diagnosis based on pathology report.
4. Willing to submit a pre-treatment tissue sample (archival, or fresh tissue if archival is not available).
Exclusion Criteria
1. Any approved anti-cancer therapy including chemotherapy, targeted small molecule therapy, systemic immunotherapy, or radiation therapy within 2 weeks prior to the first dose of study treatment; or if subject has not recovered (i.e., ≤ to Grade 1 or returned to baseline level) from AEs due to a previously administered agent; the following exceptions are allowed:
- Palliative radiotherapy for bone metastases or soft tissue lesions should be completed >7 days prior to the first dose of study treatment.
- Hormone-replacement therapy or oral contraceptives.
- Subjects with Grade 2 neuropathy or Grade 2 alopecia.

Where it is running
Running at 5 sites. Listed in: Puerto Rico, United States, Vietnam.
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?
