New drug cocktails tested for tough colorectal cancer
NCT ID NCT04294160
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tested several drug combinations in 122 adults with advanced or metastatic BRAF V600 colorectal cancer. The goal was to find safe doses and understand side effects. The trial was terminated, so final results are not available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dabrafenib, Trametinib, LTT462, LXH254, TNO155, Spartalizumab, Tislelizumab
- What this could lead to
- If successful, this could help identify safer and more effective drug combinations for treating advanced BRAF V600 colorectal cancer.
- What could go wrong
- This was a very early (Phase 1) study that was terminated, so results are limited. The combinations may not work better than existing treatments and could have significant side effects.

Key Inclusion Criteria: * Patients must have a site of disease amenable to biopsy, and be a candidate for tumor biopsy according to the treating institution's guidelines. Patients must be willing to undergo a new tumor biopsy at baseline and during on study therapy. Exceptions may be considered after documented discussion with Novartis. * All patients must have a BRAF V600 mutation confirmed by local assessment. * Patients with unresectable advanced/metastatic BRAF V600 cancer of the colon or rectum with measurable disease as determined by RECIST v1.1 * Patients must have documented disease progression following, or are intolerant to, 1 or 2 lines of chemotherapy for advanced/metastatic disease Key Exclusion Criteria: * Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy, or in-situ cervical cancer, or other tumors that will not affect life expectancy * Impairment of gastrointestinal function or gastrointestinal disease that may signficantly alter the absorption of study drugs * History of or current evidence/risk of retinal verin occlusion or serous retinopathy * History of or current interstitial lung disease or non-infectious pneumonitis * Patients with a known history of testing positive for HIV * Clinically significant cardiac disease at screening * Any medical condition that would, in the investigator's judgment, prevent the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures. * Pregnant or lactating women Other protocol-defined inclusion/exclusion may apply.
