Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a single-arm, non-randomized, single-center trial. Enroll 30 patients with HER2-expressed metastatic colorectal cancer and failure of standard therapy. Divide into 2 cohorts, including 10 patients with low HER2 expression (IHC 2+/FISH negative) and 20 patients with high HER2 expression (IHC 2+/FISH positive or IHC3+). Administer RC48-ADC intravenously in combination with bevacizumab 5mg/kg once every two weeks. Medication must be discontinued until disease progression, intolerable toxicity, informed consent is withdrawn, or investigator judgment is made. The primary endpoints is objective response rate (ORR), and secondary endpoints are progression-free survival (PFS), overall survival (OS), and adverse effects (AE).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age 18 or above, male or female;
  2. Advanced inoperable colorectal cancer confirmed by pathology;
  3. At least 1 measurable lesion meeting RECIST v1.1 criteria;
  4. Patients who had received at least oxaliplatin, irinotecan, and fluorouracil for advanced or metastatic disease progressed or were intolerant were admitted to the study; Patients who had previously received anti-HER2 therapy such as trastuzumab and lapatinib were allowed to be included;
  5. ECOG PS: 0-2 points;
  6. Patients with HER2 expression: IHC results 2+ or 3+.
  7. Predicted survival ≥12 weeks;
  8. Women of childbearing age must already be using reliable contraception or have had a pregnancy test (serum or urine) with negative results within 7 days prior to inclusion and be willing to use an appropriate method of contraception during the trial period and 8 weeks after the last test drug administration. For males, consent is required to use an appropriate method of contraception or surgical sterilization during the trial period and 8 weeks after the last administration of the trial drug;
  9. The subjects voluntarily joined the study and signed the informed consent. The subjects had good compliance and cooperated with follow-up visits.

Exclusion Criteria:

  1. Known allergy to MMAE conjugate of recombinant humanized anti-HER2 monoclonal antibody for injection;
  2. Clinical symptoms or diseases of the heart that are not well controlled, such as heart failure of grade 2 or above; b. Unstable angina pectoris; c. Myocardial infarction within 1 year; d. Clinically significant supraventricular or ventricular arrhythmias requiring treatment or intervention;
  3. There are contraindications for the use of bevacizumab such as severe active bleeding, severe arteriovenous thrombosis events, gastrointestinal obstruction and perforation, and uncontrolled hypertension
  4. Major surgical treatment, open biopsy, or significant traumatic injury was received within 28 years prior to treatment
  5. In the investigator's judgment, subjects had other factors that might have led to the termination of the study, such as other serious medical conditions (including mental illness) requiring concomitant treatment, serious laboratory abnormalities, and family or social factors that might have affected subjects' safety or the collection of data and samples.

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
Objective Response Rate
Time Frame: From Baseline to disease progress, up to 18 months
Objective Response Rate was defined as the proportion of patients with a best objective response of complete response (CR) or partial response (PR) according to RECIST criteria (version 1.1)
From Baseline to disease progress, up to 18 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
Progression free survival
Time Frame: From Baseline to primary completion date, about 2 years
Progression-free survival is defined as the time from enrollment to the first documented disease progression according to RECIST version 1.1, or to death from any cause, whichever occurred first
From Baseline to primary completion date, about 2 years
Overal survival
Time Frame: From Baseline to primary completion date, about 5 years
Time from randomization to death (from any cause)
From Baseline to primary completion date, about 5 years
