XNW27011 Study of Advanced Solid Tumor Subjects Who Failed Standard Therapies.
China240 participantsStarted 2023-07-27
Plain-language summary
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Patients are willing and able to provide written informed consent or where consent is provided by legally authorized representatives.
. Age ≥18 years old when signing the informed consent form.
. Patients with a histologically or cytologically-confirmed, locally advanced or metastatic solid tumor, which has failed on standard therapy or is intolerable to available standard therapy, or there is no available standard therapy for the tumor. The advanced solid tumors include but are not limited to gastric and gastroesophageal junction adenocarcinoma, pancreatic adenocarcinoma, esophageal adenocarcinoma, ovarian cancer, lung cancer, colorectal cancer, andbiliary tract cancer.
. The enrollment is not restricted to patients with tumor expressing CLDN18.2. However patients are required to provide tumor tissue sections for CLDN18.2 expression confirmation.
. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Phase I (Dose Escalation):To determine the maximum tolerated dose (MTD) and/or the recommended Phase 2 dose (RP2D) of XNW27011
Timeframe: Baseline up to approximately 2 years
2
Phase Ⅱ (Dose Expansion):To evaluate the objective response rate (ORR) of XNW27011 by cohorts at RP2D. The objective response includes the complete response (CR) and the partial response (PR).
. At least one measurable cancer lesion as defined by the Response Evaluation Criteria in Solid Tumors (RECIST version 1.1).
. Adequate organ function, evidenced by the following laboratory results:
Exclusion criteria
. Prior severe allergic reaction or intolerance to a monoclonal antibody, including humanized or chimeric antibodies.
. Prior severe allergic reaction or intolerance to the Topoisomerase I Inhibitor or Topoisomerase Inhibitor-Based ADC (e.g: Fam-trastuzumab deruxtecan-nxki, Sacituzumab govitecan-hziy, Irinotecan, Topotecan) or any excipient in the XNW27011 formulation.
. Having any of the following medical conditions in the past or at present:
. Acquired or congenital immunodeficiency diseases or organ transplantation.
. Past myocardial infarction (within 6 months before the first administration), hospitalization for congestive heart failure within 12 months before the first administration, severe or unstable angina, coronary or peripheral artery bypass grafting, New York Heart Association (NYHA) grade Ⅲ or IV heart failure, uncontrollable hypertension (Systolic BP ≥ 160 mmHg and/or diastolic BP ≥ 100 mmHg at rest).
. Concomitant diseases that will seriously endanger the safety of the subject or affect the completion of the tests, such as active gastrointestinal bleeding, active peptic ulcer, intestinal obstruction, intestinal paralysis, interstitial pneumonia, lung fibrosis, kidney failure, and uncontrolled diabetes(HbA1c\>8%).
. History of or currently suffering from uncontrolled primary or metastasized brain tumors, except that the investigator believes that the disease has been stabilized in patients, or whose local treatment has ended.
. History of significant cerebrovascular disease/event, including stroke or intracranial hemorrhage, within 6 months before the first dose of the XNW27011.
