About this study
Official title: Randomized, Double-blind, Phase 3 Study Evaluating TAS-102 Plus Best Supportive Care (BSC) Versus Placebo Plus BSC in Patients With Metastatic Gastric Cancer Refractory to Standard Treatments
The purpose of this trial is to compare the effects of TAS-102 and best supportive care (BSC) with Placebo (an inactive drug) and best supportive care on metastatic gastric cancer.
Read the detailed description
This is a multinational, double-blind, two-arm, parallel, randomized, Phase 3 study evaluating the efficacy and safety of TAS-102 plus BSC versus placebo plus BSC in participants with metastatic gastric cancer who have previously received at least 2 prior regimens for advanced disease. Eligible participants will be centrally randomized (2:1) to TAS-102 + BSC (experimental arm) or placebo + BSC (control arm).
- Conditions
- Refractory Metastatic Gastric Cancer
- Being tested
- TAS-102, Placebo
- Keywords
- Gastric Cancer, Metastatic Gastric Cancer
- Medical subject headings
- Stomach Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
TAS-102Drug
35 mg/m2/dose of TAS-102 orally, twice daily on days 1-5 and days 8-12 of each 28-day cycle.
PlaceboDrug
35 mg/m2/dose of placebo orally, twice daily on days 1-5 and days 8-12 of each 28-day cycle.
| Study group | Role | What they receive |
|---|---|---|
| TAS-102+BSC | Experimental | Participants received 35 milligrams per meter square (mg/m^2) of TAS-102 tablets orally twice daily (BID) for 5 days per week (i.e., from Days 1 to 5 and Days 8 to 12) for 2 weeks followed by 14 days rest in each 28-day cycle along with BSC until a discontinuation criterion (participant withdrawal, disease progression, irreversible treatment-related Grade 4 non-hematologic event, physician's decision, pregnancy or death) was met. Receives: Drug: TAS-102 |
| Placebo+BSC | Experimental | Participants received 35 mg/m^2 of matching placebo for TAS-102 tablets orally BID for 5 days per week (i.e., from Days 1 to 5 and Days 8 to 12) for 2 weeks followed by 14 days rest in each 28-day cycle along with BSC until discontinuation criterion (participant withdrawal, disease progression, irreversible treatment-related Grade 4 non-hematologic event, physician's decision, pregnancy or death) was met. Receives: Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Overall Survival (OS)
OS was defined as the time from the date of randomization to the date of death due to any cause. Participants without documented death were censored at last follow-up or cut-off date, whichever comes first. OS was estimated by Kaplan-Meier method.
Measured: From the date of randomization to the data cut-off date (maximum duration: up to approximately 46 months)
Secondary outcomes (2)
Progression-Free Survival (PFS)
PFS was defined as the time from randomization until the date of first occurrence of investigator-assessed radiological disease progression or death due to any cause, whichever came first. Disease progression as per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) for target lesions were defined as target lesions with at least 20 % relative increase in the sum of diameters with reference to the smallest sum on study, including the baseline sum and this sum demonstrated an absolute increase of at least 5 millimeter (mm) or the appearance of one or more new lesions or Unequivocal progression of existing non-target lesions. All alive participants with no disease progression as of the analysis cut-off date were censored at the last tumor assessment. PFS was estimated by Kaplan-Meier method.
Measured: From the date of randomization to the cut-off date (maximum duration: up to approximately 46 months)
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAE)
Any untoward medical condition that occurs in a participants while participating in a clinical study and does not necessarily have a causal relationship with the use of the study medication was considered an adverse event (AE). A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. TEAEs/TESAEs were defined as events that started on or after treatment or started before treatment and worsened after the start of treatment through 30 days after the last dose of study treatment.
Measured: From the first dose of study treatment until 30 days after the last dose of study treatment (maximum duration: up to approximately 46 months)

A Phase 3 study testing TAS-102 in people with Refractory Metastatic Gastric Cancer, run by Taiho Oncology, Inc. at 139 sites in 18 countries.
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 7 inclusion and 5 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 139 sites in United States, Italy, France, Turkey (Türkiye), Japan and 13 more countries. 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 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?
Yes. Results are posted in the registry (first posted 16 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Overall Survival (OS) (time frame: From the date of randomization to the data cut-off date (maximum duration: up to approximately 46 months)). 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 NCT02500043, which also lists 6 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 3 Sep 2024; AzTrials last refreshed its copy on 7 Nov 2026.
