About this study
Official title: A Phase I/II, Open-Label, Nonrandomized, Dose-Finding Safety, Tolerance, Pharmacokinetic, and Efficacy Study of Orally Administered S-1 in Combination With Cisplatin in Patients With Advanced Gastric Cancer
The purpose of the phase 1 portion of the study is to determine the safe dose of S-1 and cisplatin that can be administered in gastric cancer patients.
The purpose of the phase 2 portion of the study is to determine the antitumor activity of the S-1 and cisplatin regimen established from phase 1 in patients with advanced gastric cancer.
Read the detailed description
S-1 is an oral fluoropyrimidine which combines tegafur (a 5-FU prodrug) with two classes of modulators which:
- inhibit dihydropyrimidine dehydrogenase (DPD) and
- block phosphorylation of 5-FU in gastrointestinal tissues.
S-1 is designed to enhance the the clinical utility of an oral fluoropyrimidine while ameliorating the disadvantage of gastrointestinal toxicity.
5-Fu and cisplatin have been used as a standard treatment in gastric cancer and preliminary data indicate that S-1 plus cisplatin may result in superior tolerability and efficacy in advanced gastric cancer.
S-1 is currently approved in Japan for treatment of gastric cancer and head and neck cancer.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of the phase 1 portion of the study is to determine the safe dose of S-1 and cisplatin that can be administered in gastric cancer patients.
The purpose of the phase 2 portion of the study is to determine the antitumor activity of the S-1 and cisplatin regimen established from phase 1 in patients with advanced gastric cancer.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing S-1 and cisplatin in people with Gastric Cancer, run by Taiho Oncology, Inc. at 11 sites in United States.
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 17 inclusion and 13 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: finished, as of the sponsor's last update on 3 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in United States. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
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 3 Sep 2024; AzTrials last refreshed its copy on 7 Nov 2026.
