Publication in Cancer Research Details Atebimetinib’s Broad, Durable Preclinical Activity and Favorable Tolerability Across RAS- and RAF-Mutant Tumors via Deep Cyclic Inhibition
July 21, 2026 4:05 PM EDT- Atebimetinib showed broad antitumor activity across KRAS-, NRAS-, and BRAF-mutant models, including colorectal, lung, and melanoma, by resisting the RAF-mediated bypass signaling that has constrained other MEK inhibitors -
- In head-to-head in vivo studies, atebimetinib produced deeper, more durable tumor growth inhibition than the FDA-approved MEK inhibitor binimetinib -
- Atebimetinib was associated with favorable tolerability in preclinical models, consistent with Deep Cyclic Inhibitor technologys design to decouple antitumor activity from the toxicity of continuous MAPK suppression -
- In a preclinical cancer... More
