C4 Therapeutics, Inc. announced that the first patient has been dosed in its Phase 1/2 clinical trial of CFT1946, an orally bioavailable mutant-selective BiDAC(TM) degrader for the treatment of BRAF V600 mutant solid tumors. The Phase 1/2 clinical trial will primarily investigate safety, tolerability, and anti-tumor activity, with secondary and exploratory objectives to characterize the pharmacokinetic and pharmacodynamic profile of CFT1946. The initial arm of the Phase 1 portion of the study will evaluate CFT1946 as a single agent in patients with BRAF V600 mutant solid tumors. As the Phase 1 trial progresses, an additional arm of the trial will evaluate CFT1946 in combination with
trametinib, also in patients with BRAF V600 mutant solid tumors. Following the identification of the recommended dose(s), the Phase 2 portion of the trial is expected to expand to three investigational arms to evaluate: (1) CFT1946 monotherapy in patients with V600 mutant melanoma or non-small cell lung cancer (NSCLC) after prior BRAF inhibitor treatment; (2) CFT1946 in combination with trametinib in patients with V600 mutant melanoma or NSCLC after prior BRAF inhibitor treatment; and (3) CFT1946 in combination with trametinib in patients with V600 mutant NSCLC who have not previously been treated with a BRAF inhibitor. CFT1946 is C4T's third oncology program to enter clinical studies from its proprietary TORPEDO(R) platform.
