A Phase II/III Study of HR070803 in Combination With Oxaliplatin, 5-fluorouracil, Calcium Folinate and Bevacizumab Versus FOLFOX in Combination With Bevacizumab for First-line Treatment of Advanced Colorectal Cancer

November 16, 2025 updated by: Jiangsu HengRui Medicine Co., Ltd.

A Phase II/III, Double-blind, Randomized, Multi-center Study of HR070803 in Combination With Oxaliplatin, 5-fluorouracil, Calcium Folinate and Bevacizumab Versus FOLFOX in Combination With Bevacizumab for First-line Treatment of Advanced Colorectal Cancer

This is a double-blind, randomized, multi-center, II/III study in at least 606 patients with advanced colorectal cancer. The study is being conducted to evaluate the safety of HR070803 combined with oxaliplatin, 5-FU/LV and bevacizumab in phase II and to evaluate the efficacy of HR070803 in combination with oxaliplatin, 5-FU/LV, and bevacizumab versus HR070803 simulator in combination with FOLFOX and bevacizumab for first-line treatment of patients with unresectable metastatic colorectal cancer.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adverse Events (AE) According to NCI-CTCAE v5.0（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant after signing the informed consent form and which does not necessarily have to have a causal relationship with this treatment. An AE could be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a study treatment, whether or not considered related to the study treatment. Any worsening (i.e., any clinically significant adverse change infrequency and/or intensity) of a preexisting condition that is temporally associated with the use of study treatment, is also an AE.
From Baseline to primary completion date, about 48 months
Serious Adverse Events (SAE)（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
An SAE is defined as any of the following adverse events in a participant or clinical investigation participant after signing the informed consent form and which does not necessarily have to have a causal relationship with this treatment: events that result in death, life-threatening events; events requiring hospitalization or prolonged hospitalization; events leading to permanent or severe disability/loss of function (significant impairment of the ability to carry out normal life functions); congenital abnormalities or birth defects; a medically important event or intervention may be required to prevent any of these outcomes.
From Baseline to primary completion date, about 48 months
Progression-Free Survival (PFS) Assessed by IRC（Phase III）
Time Frame: From Baseline to primary completion date, about 48 months
from randomization to PD or death from any cause
From Baseline to primary completion date, about 48 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Response Rate (ORR) Assessed by investigator（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
The proportion of patients who acquired complete response and partial response during treatment.
From Baseline to primary completion date, about 48 months
Disease Control Rate (DCR) by investigator（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
The proportion of patients who acquired complete response and partial response and stable disease during treatment.
From Baseline to primary completion date, about 48 months
Duration of Overall Response (DoR) by investigator（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
For subjects who demonstrated CR or PR, response duration is defined as the time from the date of first response (CR or PR) until the date of first documented disease progression or death.
From Baseline to primary completion date, about 48 months
Progression-Free Survival (PFS) Assessed by investigator（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
from randomization to PD or death from any cause.
From Baseline to primary completion date, about 48 months
Overall Survival (OS)（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months
from randomization to death from any cause.
From Baseline to primary completion date, about 48 months
Characterize the PK（Phase II）
Time Frame: From Baseline to primary completion date, about 48 months

Duration of Overall Response (DoR) by IRC and investigator（Phase III）
