About this study
The purpose of this study is to determine maximum tolerated dose (MTD), dose limiting toxicities (DLT) and recommend a proper dose for our phase II study of S-1 when combined with radiation therapy for locally advanced or recurrent gastric cancer.
Read the detailed description
This is a Phase I trial of S-1 given in treatment days with an oral dose from 30mg/m2/d to 80mg/m2/d, concurrently with radiation in patients with locally advanced or locally recurrent gastric cancer. Patients will be treated with external beam radiation therapy in a standard manner. S-1 will be administered for 6 dose levels,30/40/50/60/70/80mg/m2/d. Patients will be assessed for acute toxicities according to Common Toxicity Criteria for Adverse Effects (CTCAE)3.0.

What is being measured
The primary outcome is the main question the study is designed to answer.
To define dose limited toxicities(DLT) of S-1, peroral BID, in treatment days concurrently with radiation therapy (RT) in locally advanced or recurrent gastric cancer.
Dose limited toxicities defined as below: leucopenia ≥4 neutropenia ≥ 4, anemia ≥ 3, thrombocytopenia ≥ 3, alanine aminotransferase/aspartate aminotransferase (AST) ≥ 3, alkaline phosphatase (ALT) ≥ 3, total bilirubin ≥ 3,blood urea nitrogen (BUN)/Cr ≥ 2,non-granular cell decreased fever ≥ 2, nausea/vomiting ≥ 2, fatigue ≥ 3, weight loss ≥ 3, diarrhea ≥ 3, abdominal pain ≥ 3, dysphagia ≥ 3, hand-foot syndrome ≥ 2, neurotoxicity ≥ 2.
Measured: up to 9 weeks
Secondary outcomes (1)
To define maximum tolerated dose(MTD) of S-1, peroral BID, in treatment days concurrently with radiation therapy
If 1 of 3 patients treated within a S-1 dose level experiences DLTs, 3 more patients will be treated at the same level. If a second patient experiences DLTs, then escalation will be stopped and the MTD is defined as the level below DLT dose level.
Measured: up to 9 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing S-1 in people with Gastrointestinal Neoplasms and Gastric Cancer, run by Chinese Academy of Medical Sciences 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 14 inclusion and 7 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 18 Sep 2013. 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 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.
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.
What does the primary outcome measure?
To define dose limited toxicities(DLT) of S-1, peroral BID, in treatment days concurrently with radiation therapy (RT) in locally advanced or recurrent gastric cancer. (time frame: up to 9 weeks). 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 NCT01291407, which also lists 13 linked publications.
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 18 Sep 2013.
