About this study

Official title: A Randomized, Multicenter, Phase Ⅱ/Ш Clinical Study to Evaluate the Efficacy of KN026 in Combination With Chemotherapy in Subjects With HER2 Positive Advanced Unresectable or Metastatic Gastric Cancer (Including Gastro-esophageal Junction Adenocarcinoma) Who Have Failed First-line Therapy.

KN026-001 is a two-stage study (Open-label stage/Randomized stage). Open-label stage is designed to evaluate the safety and efficacy of KN026 and chemotherapy when given together. Randomized stage is designed to evaluate the OS and PFS in patients receiving KN026 and chemotherapy compared to patients receiving placebo and chemotherapy.

Read the detailed description

KN026-001 is a two-stage randomized, multicenter, phase Ⅱ/Ⅲ clinical study to evaluate the efficacy of KN026 in combination with chemotherapy in subjects with HER2-positive advanced unresectable or metastatic gastric cancer, including adenocarcinoma of the gastro-esophageal junction, who have failed first-line therapy.

Stage 1 is an open-label, multicenter, phase Ⅱ study to evaluate the safety and ORR in subjects receiving KN026 in combination with chemotherapy. Stage 2 is a randomized, double-blind, placebo-controlled phase Ш study to evaluate the OS and PFS in subjects receiving KN026 in combination with chemotherapy compared to placebo in combination with chemotherapy.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing KN026/Placbo Injection, Paclitaxel Injection and Docetaxel Injection in people with Stomach Cancer, run by Shanghai JMT-Bio 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 11 inclusion and 30 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: looking for participants now, as of the sponsor's last update on 19 Dec 2023. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression Free Survival (PFS) according to RECIST 1.1 by IRC (time frame: Up to 2.5 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?
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 19 Dec 2023.
