About this study

Official title: A Phase Ib/II Study to Evaluate the Safety and Efficacy of IBI363 in Combination With Bevacizumab With or Without Nab-Paclitaxel as Second-Line Therapy in Patients With Advanced Gastric Cancer

This study is for patients with advanced or metastatic gastric cancer whose disease has worsened after first-line systemic therapy. IBI363 is an investigational antibody that may help the immune system recognize and attack cancer cells. This trial will evaluate IBI363 in combination with bevacizumab, with or without nab-paclitaxel, as a second-line treatment.

The study has two parts. In the phase Ib part, small groups of patients will receive IBI363 plus bevacizumab with or without nab-paclitaxel to evaluate the safety, side effects, and tolerability of the combination and to determine an appropriate dose for further study. In the phase II part, additional patients will receive the selected regimen to assess the preliminary antitumor activity of IBI363 in combination with bevacizumab ± nab-paclitaxel, including tumor response and other clinical outcomes, as well as to further describe the safety profile. Treatment will continue until disease progression, unacceptable toxicity, withdrawal of consent, or other reasons defined in the protocol.

    Measured: 12 months after the last subject participating in

  3. Time to Response (TTR)

    Time to response is defined as the time from first dose of study treatment to the date of first documented CR or PR according to RECIST v1.1.

    Measured: 12 months after the last subject participating in

  4. Duration of Response (DoR)

    Duration of response is defined as the time from the first documented CR or PR to the first documented disease progression or death from any cause, according to RECIST v1.1.

    Measured: 12 months after the last subject participating in

  5. Progression-Free Survival (PFS)

    Progression-free survival is defined as the time from first dose of study treatment to the first documented disease progression according to RECIST v1.1 or death from any cause, whichever occurs first.

    Measured: 12 months after the last subject participating in

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing IBI363, Bevacizumab and Nab-paclitaxel in people with Advan'ce'd and Advanced, run by The First Affiliated Hospital of Zhengzhou University 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 29 inclusion and 45 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: opening soon, as of the sponsor's last update on 23 Jan 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 combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Yongxu Jia (0086-15237128281, fccjiayx@zzu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence and Severity of Adverse Events (time frame: From first dose of study treatment until 90 days after the last dose or end of study, whichever occurs first.). 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 23 Jan 2026.
