What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Injectable ALK-N001Drug

    Also called QHL-1618

    Injectable ALK-N001 is administered intravenously every 2 weeks (Q2W; 28-day treatment cycle). Two predefined dose levels are available: 37.5 mg/m² (Dose A) and 50 mg/m² (Dose B). Enrollment or suspension of dose groups may be determined by the Safety Review Committee (SRC) based on safety, PK, PD and preliminary anti-tumor activity data.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate (ORR), assessed per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1

    ORR is defined as the proportion of participants with confirmed complete response (CR) or partial response (PR) as evaluated by RECIST V1.1.

    Measured: Up to approximately 24 months from the first dose.

Secondary outcomes (7)
  1. Duration of Response (DOR)

    Description: DOR is defined as the time from the first documentation of CR/PR until the first documented progressive disease (PD) or death from any cause.

    Measured: Up to approximately 24 months from the first dose.

  2. Disease Control Rate (DCR)

    DCR is the proportion of participants achieving CR, PR, or stable disease (SD) per RECIST V1.1.

    Time Frame: Up to approximately 24 months from the first dose.

    Measured: Up to approximately 24 months from the first dose.

  3. Progression-Free Survival (PFS)

    PFS is the time from study enrollment to documented PD or death from any cause. 6-,12-,24-month PFS rates will be calculated.

    Measured: Up to approximately 24 months from the first dose.

  4. Overall Survival (OS)

    OS is defined as the time from enrollment to death from any cause. 12-,24-month OS rates will be calculated.

    Measured: Up to approximately 24 months from the first dose.

  5. Safety (Adverse Events and Serious Adverse Events)

    Incidence, severity and relatedness of AEs and SAEs; laboratory tests, 12-lead ECG, vital signs, physical examination and ECOG performance status.

    Measured: From informed consent until 28±7 days after last dose.

  6. Population Pharmacokinetics (PopPK) of total DXD and free DXD

    Characterize PopPK profiles of total DXD and free DXD.

    Measured: From first dose up to end of treatment.

  7. Exposure-Response (E-R) relationship of total DXD and free DXD

    E-R relationship between total/free DXD exposure and efficacy, safety and biomarkers.

    Measured: From first dose up to approximately 24 months after first dose.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Injectable ALK-N001 in people with Advanced Gastrointestinal Tumors, run by Zhejiang Anglikang Pharmaceutical Co., Ltd..

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 16 inclusion and 21 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 17 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

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 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?

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?

Objective Response Rate (ORR), assessed per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (time frame: Up to approximately 24 months from the first 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 17 Sep 2026.
