About this study

Official title: A Phase I/Ⅱ, First-in-Human Study of XNW27011 in Patients With Locally Advanced and/or Metastatic Solid Tumors

This is a global, multi-center, open-label, Phase I/II first-in-human study of XNW27011 monotherapy as an investigational product (IP) in patients with locally advanced and/or metastatic solid tumors who have failed or are intolerant to standard therapies. XNW27011 is an antibody-drug conjugate (ADC) targeting Claudin 18.2 (CLDN18.2), a transmembrane protein important to tight junctions. The study consists of 2 parts: Part 1 is the dose-escalation phase (Phase I), and Part 2 is the does-expansion phase (Phase II). In phase I part of the study, approximately 42 patients with locally advanced and/or metastatic solid tumors will be enrolled, irrespective of CLDN18.2 expression. However, the most recently available tumor tissue specimen will be collected (if available) for a retrospective CLDN18.2 expression confirmation. In phase II part of the study, only patients with confirmed CLDN18.2 expression by IHC in the central laboratory will be enrolled.The phase II part of the study will consist of the following four groups，Up to three dose cohorts for each patient group are planned currently. Each dose cohort will include approximately 20 patients. Approximately 240 patients evaluable will be enrolled in Phase Ⅱ part of the study.

What participants receive

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

  • XNW27011Drug

    Eligible patient(s) in each dose cohort will receive the assigned XNW27011 dose administration every 3 weeks (Q3W, cycle) until intolerable toxicity, progression of the disease without clinical benefit, or withdrawal of informed consent.

    An accelerated titration scheme will be used for the first two dose levels (0.6 mg/kg and 1.2 mg/kg) starting from 0.6 mg/kg dose as follows:

    The first patient will be enrolled for 0.6 mg/kg dose. If the subject shows no significant toxicity in cycle 1 (DLT observation period), the second patient will be enrolled for 1.2 mg/kg.

    3 + 3 dose escalation:3 patients will be enrolled to the dose cohort first，If 1 of 3 patients experiences a DLT, up to 3 more patients will be enrolled in the same dose cohort.. If none of the additional 3 patients experiences a DLT, dose escalation will continue to the next dose.Dose escalation will be stopped when 2 or more patients out of 3 to 6 patients at the same dose level experience a DLT.

  • XNW27011Drug

    Group A: Gastric/gastroesophageal junction adenocarcinoma with CLDN18.2 expression, tentatively expand with 3.6, 3.0, 2.4 mg/kg. Group B: Pancreatic adenocarcinoma with CLDN18.2 expression, tentatively expand with 3.6, 3.0, 2.4 mg/kg. Group C: Ovarian cancer with CLDN18.2 expression, tentatively expand with 3.6, 3.0, 2.4 mg/kg. Group D: Other tumors with CLDN18.2 expression, including but not limited to esophagus adenocarcinoma, lung cancer, colorectal cancer, and biliary tract cancer,tentatively expand with 3.6, 3.0, 2.4 mg/kg.

Study groups in NCT06792435
Study groupRoleWhat they receive
Phase I Dose EscalationExperimentalBased on the preclinical data of XNW27011, the dose-escalation study will start from the initial dose of 0.6 mg/kg. Dose escalation will be performed by using a modified Fibonacci method with a slightly fine-tuned dose escalation amplitude. The first two dose escalations will be by 100% of the preceding dose and thereafter by 50%, 33%, 25% and 25% of the preceding doses. Therefore, there are 7 dose cohorts for projected dose escalations as follows
Receives: Drug: XNW27011
Phase II: Expanded cohortsExperimentalThe SRC will select up to 3 recommended doses for Phase II study based on the safety, PK, ADA and preliminary efficacy data from Phase I study (dose escalation). Phase Ⅱwill include 4 patient groups, and up to 3 dose cohorts for each patient group. Approximately 20 Chinese or U.S. patients will be enrolled to each dose cohort with an approximately total of 240 patients in the Phase II study to further evaluate the antitumor activity, safety, tolerability, PK and incidence of ADA for XNW27011.
Receives: Drug: XNW27011

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing XNW27011 in people with Pancreatic Adenocarcinoma Metastatic and Lung Cancer (NSCLC), run by Astellas Pharma Global Development, Inc. 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 44 inclusion and 48 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: under way, not looking for participants, as of the sponsor's last update on 11 Aug 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?

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?

Phase I (Dose Escalation):To determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of XNW27011 (time frame: Baseline up to approximately 2 years). 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?

On the ClinicalTrials.gov record for NCT06792435.

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.
