Title:

P6-10-13 An update to a Phase I trial of CFI-402257, an oral TTK inhibitor, in patients with advanced solid tumors with HER2-negative breast cancer expansion cohorts

Published date:
11/22/2022
Excerpt:
CFI-402257 was dosed once daily on a continuous schedule in 28-day cycles at a starting dose of 5 mg….advanced Her2-negative (ER+ or TNBC) with 1-4 prior lines of chemotherapy for metastatic disease (Cohort B), and ER+/Her2- breast cancer in combination with Fulvestrant...CFI- 402257 is well tolerated as mono and combination with fulvestrant. Efficacy signals are emerging with pts in the combo cohort demonstrating anti-tumor activity.

Abstract P1-18-17: Phase I study of cfi-402257, an oral ttk inhibitor, in patients with advanced solid tumors with breast cancer expansion cohorts

Published date:
02/15/2022
Excerpt:
PR’s confirmed by the Investigator have been seen to date in 33% of the cohort C subjects (2/6 patients), with an additional two cPR’s seen in the breast cancer population (ER+/HER2-) from the expansion cohorts….CFI-402257 is generally well tolerated and continues to enroll at 168 mg daily with a manageable AE profile and early signs of anti-tumor activity.
