  11. The antibody titer of the neutralizing antibody

    The immunogenicity of M802 will be collected by testing the antibody titer of the neutralizing antibody.

  12. ORR

    Objective response rate (ORR) is defined as the proportion of patients with complete response (CR) and partial response (PR), based on RECIST Version 1.1.

    Measured: From the time of first dosing (Day 1) until disease progression or toxicity intolerance (up to 1 years).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Chort 1 of M802, Chort 2 of M802 and Cohort 3 of M802 in people with HER2-Positive Solid Tumors, run by Wuhan YZY Biopharma 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 13 inclusion and 17 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 20 Jul 2025. 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?

MTD (time frame: From the time of first dosing (Day 1) until the forth dosing (Day 28)). The study lists 2 primary outcomes in all. 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 20 Jul 2025.
