RAS Targeted Therapy Resistance Breakthrough: mTORC1 is Key, Dalifarnib Combination Therapy Brings Hope

2026-03-12 07:35:33

RAS mutations account for approximately 30% of malignancies, but resistance limits clinical benefits. New research reveals sustained mTORC1 activity as a non-genetic driver of RAS inhibitor resistance. Farnesyltransferase inhibitor Dalifarnib (KO-2806) blocks mTORC1 activation via RHEB, achieving rapid durable tumor regression when combined with RAS inhibitors.
