About

Fruquintinib with PD-1 inhibitors (FP) and TAS-102 with bevacizumab (TB) are two common therapies for patients with previous-treated metastatic colorectal cancer (mCRC). However, it's still not clear that which therapy can bring better prognosis. Our study sought to investigate the efficacy and safety of fruquintinib with PD-1 Inhibitors versus TAS-102 with bevacizumab in Late-Line mCRC between July 2019 to October 2022July 2019 and June 2021 at the Hunan Cancer Hospital.

Full description

This is a retrospective cohort study conducted in Hunan Cancer Hospital. Patients (pts) with mCRC who had received at least the 2nd line treatment were eligible. Propensity score (PS) would be calculated to balance the baseline characteristics of two arms. Overall survival (OS) was set as the primary endpoint. From July 2019 to October 2022, 106 eligible pts in total were enrolled. According to the treatment received, 72 and 34 pts were respectively allocated into FP cohort and TB cohort.

Enrollment: 106 patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers

Trial design

106 participants in 2 patient groups

Fruquintinib plus PD-1 inhibitors

Description:

In fruquintinib plus PD-1 inhibitors group,The patients were treated orally with Fruquintinib (5mg once daily for 14 days on/7 days off, over a 21-day cycle), combined with 1 of the 5 anti-PD-1 antibodies (i.e., nivolumab, pembrolizumab, camrelizumab, sintilimab, or toripalimab). The anti-PD-1 antibody was administered intravenously on day 1, and its recommended dosage was as follows: nivolumab: 240 mg, every 2 weeks; pembrolizumab, camrelizumab, and sintilimab: 200 mg every 3 weeks; and toripalimab: 240 mg every 3 weeks.

Treatment:

Drug: Fruquintinib

Drug: PD-1 inhibitors

TAS-102 plus bevacizumab

Description:

In TAS-102 plus BEV group, Patients received TAS-102 (35 mg/m²orally twice a day on days 1-5 and 8-12, every 28 days) and bevacizumab (5 mg /kg, intravenously, on days 1 and 15, every 28 days). Bevacizumab was approved to be a 30-minute intravenous infusion before TAS-102.

Treatment:

Drug: Trifluridine/Tipiracil

Drug: Bevacizumab
