About this study
Official title: A PhaseⅠ,Open-label, Single-center Study to Evaluate Safety and Pharmacokinetics of Recombinant Anti-Epidermal Growth Factor Receptor (EGFr) Antibody in Patients With Metastatic Colorectal Cancer
A single-central,open-label,safety,pharmacokinetics,phase I study. Biological:Recombinant Anti-EGFr Antibody Two dose levels: Low-dose level patients received initial dose 100 mg/m2 and 4 weeks later 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.High-dose level patients received cetuximab initial dose 400 mg/m2 and 4 weeks later loading 400 mg/m2 and 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.
Read the detailed description
Two dose levels were tested: Recombinant Anti-EGFr Antibody Low-dose level patients received initial dose 100 mg/m2 and 4 weeks later 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent.High-dose level patients received cetuximab initial dose 400 mg/m2 and 4 weeks later loading 400 mg/m2 and 250 mg/m2 weekly maintenance to the disease progression or unacceptable toxicity or death or withdraw informed consent. Dose limiting toxicity (DLT) was defined as: grade 4 or 3-time grade 3 cutaneous toxicity,successive 3-time infusion suspension due to grade 3 cutaneous toxicity,any other ≥grade 3 adverse reaction or acute pneumonia, interstitial pneumonia, and other lung diseases.
Cohorts of 3 patients receive single dose of low-dose group of Recombinant Anti-EGFr Antibody. If the ratio of the dose limiting toxicity (DLT) after a single dose is not more than a third, then high-dose group can be treated.After high-dose(initial dose 400 mg/m2, iv., 2 h),safety will be observed and blood sampling will be taken for a single dose pharmacokinetic analysis.After 4-week continuous administration (loading dose 400 mg/m2, iv., 2 h; maintenance dose 250 mg/m2, iv, 1 h, q1w) until disease progression, unacceptable toxicity reaction, death or revocation of informed consent.As the blood concentration reach steady state, blood sampling will be collected for steady-state pharmacokinetic analysis, for 1 week.After completion of the steady-state pharmacokinetics,patients can receive chemotherapy,and safety (including immunogenicity) and curative effect will be observed.

Measured: 4 weeks after the single dose
Secondary outcomes (2)
Change from baseline in serum antibody and its neutralizing ability
Measured: Prior to the single dose on day 1 and on the 1st day of 1、2、4、6、9 week after the first administration until 1 month after the last administration.
Pharmacokinetics (PK): Area Under the Concentration Curve (AUC) of anti-EGFR antibody after single dose and under the stable blood concentration.
Measured: 4 weeks after the single dose and 1 week under the stable blood concentration after weekly administration.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Recombinant Anti-EGFr Antibody in people with Metastatic Colorectal Cancer, run by Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd. at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 12 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of patients with dose limiting toxicity. (time frame: 4 weeks after the single dose). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 May 2026.
