Abstract 88P

Background

In patients with refractory CRC, FTD–TPI has been associated with a significant improvement in overall survival (OS). However, there is no data regarding the activity of FTD–TPI in patients with BRAF mt mCRC. Our aim is to describe the safety and activity of FTD–TPI in patients with BRAF mt mCRC.

Methods

This is a multicenter, international cohort including patients with BRAF mutated mCRC treated with FTD–TPI from 2016 to 2023, at 4 hospitals in Spain and Italy. Survival analysis was performed using Kaplan-Meier curves. Analysis on OS was calculated in the overall population and based on the already published prognostic groups (ESMO Open 2020): good prognosis characteristics -GPC- (< 3 metastatic sites and time from metastases to FTD–TPI≥ 18 months), and poor prognosis characteristics -PPC- (≥ 3 metastatic sites or time from M1 to TAS < 18 months).

Results

Overall, 26 patients were included, median age was 69 years, 13 (50%) patients were female, and 20 (77%) patients had ECOG 1. Regarding tumor characteristics, (14) 56% of the tumors were right-sided, 6 (23%) tumors were MSI, and 13 (50%) patients had liver metastases. 54% of the patients had previously received ≥4 lines, and 17 patients received only 1-2 FTD–TPI cycles (range 1-7). Median progression-free survival (mPFS) was 2.3 months (m) (95%CI 2.0-3.2 m), whereas mOS was 6.6 m (95%CI 4.4-12 m). mOS based on prognostic groups were 7.6 m vs 4.2 m (HR 0.65, 95%CI 4-10, p 0.3) for patients with GPC (n: 14) and PPC (n: 12) respectively. Exploratory analysis identified ECOG as the only feature associated with survival. Patients with ECOG 0, 1, and 2 had a mOS of 12 m (reference), 5.9 m (HR 1.65 95%CI 0.47-5.80, p 0.4), and 1.7 m (HR 6.03 95%CI 1.1-33, p 0.038). Dose modifications were required in 40% of the patients, and G3-4 adverse events (AE) were observed in 19% of the patients. The most frequent G3-4 AEs were neutropenia (8%), anemia (8%), and asthenia (4%).

Conclusions

Overall, patients with BRAF mutant mCRC achieved modest benefit when treated with FTD–TPI. However, pts with GPC and ECOG 0 achieved longer OS compared with PPC or ECOG 1-2 pts. Thus, FTD–TPI remains a therapeutical option for some pts with BRAF mt mCR. Because of modest sample size, further validation is needed.
