Awards & highlights


This trial is testing the safety and effectiveness of combining two drugs, ZEN003694 and binimetinib, to treat patients with solid tumors that have spread or can't be removed by surgery.

Who is the study for?
Adults with advanced/metastatic or unresectable solid tumors that have specific RAS alterations, including triple negative breast cancer. Participants must be in a stable condition, not pregnant or breastfeeding, and willing to use contraception. They should be beyond certain periods after previous treatments and agree to sign informed consent.Check my eligibility
What is being tested?
The trial is testing the combination of ZEN003694 (a BET protein inhibitor) and binimetinib (a kinase inhibitor) on patients with solid tumors having RAS mutations. The study has two parts: finding the best dose without severe side effects and then giving this dose to more people to learn about its safety.See study design
What are the potential side effects?
Potential side effects include issues related to organ inflammation, digestive system disturbances, blood disorders, fatigue, increased risk of infection due to immune system suppression, as well as possible reactions at the infusion site.

1Treatment groups
Experimental Treatment
Group I: Treatment (ZEN-3694, binimetinib)Experimental Treatment6 Interventions
Patients receive ZEN-3694 PO QD and binimetinib PO BID on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. During the dose expansion phase, patients will have two mandatory biopsies - one before beginning the study and the second at day 15 of cycle 1. The study biopsy takes small pieces of cancer tissue from patient's body to look for markers (substances made by, on, or in tumor cells) related to how the study treatment works. Patients also undergo collection of blood samples at screening and on study and undergo CT or MRI throughout the trial.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
BET inhibitors, like ZEN003694, work by targeting bromodomain and extra-terminal proteins that regulate genes essential for cancer cell growth and survival. MEK inhibitors, such as Binimetinib, block the MEK1 and MEK2 proteins in the MAPK/ERK pathway, which is often overactive in cancer cells, leading to uncontrolled proliferation. These targeted therapies are important for cancer patients because they can more precisely disrupt the specific pathways driving their cancer, potentially leading to better outcomes and fewer side effects compared to traditional chemotherapy.
