About this study

Official title: A Phase II Study of Gemcitabine and TS-1 in Patients With Previously Untreated Metastatic or Recurrent Biliary Tract Cancer

In current study, we evaluate the efficacy of gemcitabine and TS-1 combination chemotherapy in advanced BTC.

Read the detailed description

At present, surgery is the only curative treatment option for biliary tract cancer (BTC). However, less than 25% of patients are resectable at presentation with high relapse rates after surgery. Because of the low incidence and heterogeneity of BTC, clinical trials are difficult to conduct in these patients, hampering the evaluation of optimal chemotherapy regimens. Owing to the lack of randomized phase III studies, there is no standard regimen for palliative chemotherapy of GBC and CC. But the exploration of an optimal regimen for standard first-line chemotherapy for BTC is imperative in order to improve survival in these patients.

Gemcitabine has demonstrated antitumor activity as monotherapy in phase II trials in BTC patients with response rates ranging from 22 to 36% (2001 Proc Am Soc Clin Oncol 20:A626, 2001 J Clin Oncol 19(20):4089-4091, 2001 Ann Oncol 12(2):183-186).

As with most gastrointestinal tumors, 5-fluorouracil (5-FU) is the most studied drug as a single agent or a combination in different dosages and schedules with response rates of 10-20% and with median survival of 7-9 months in BTC (2005 Cancer 103:111-118, 2001 Clin Cancer Res 7:3375-3380).

The combination of gemcitabine and fluoropyrimidine in biliary cancers is worthy of further evaluation. The toxicity profiles of these agents are known to be non-overlapping, and combinations have been well tolerated. Oral fluoropyrimidines are considered to be an alternative to conventional protracted 5-FU infusion as far as they provide comparable efficacy and compliance.

S-1 is oral fluoropyrimidine preparation developed by Taiho Pharmaceutical Co., Ltd. (Tokyo, Japan) that combines tegafur with two 5-FU modulators, 5-chloro-2, 4-dihydroxypyridine (CDHP) and potassium oxonate (Oxo), in a molar ratio of 1:0.4:1. Tegafur, a prodrug of 5-FU, is converted to 5-FU mainly in liver and tumor cells. CDHP, a reversible inhibitor of dihydropyrimidine dehydrogenase, suppresses the degradation of 5-FU, thereby maintaining high concentrations of 5-FU in plasma and tumor cells. CDHP also decreases cardiotoxic and neurotoxic effects by reducing the production of F-b-alanine (FBAL), the main catabolite of 5-FU. Several phase II trials showed that TS-1 monotherapy or combination with CDDP, paclitaxel or irinotecan was effective palliative treatment option for advanced gastric cancer and colorectal cancer.

In current study, we evaluate the efficacy of gemcitabine and TS-1 combination chemotherapy in advanced BTC.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Gemcitabine TS-1 in people with Biliary Tract Cancer, run by Samsung Medical Center.

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 1 inclusion and 1 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: stopped early, as of the sponsor's last update on 21 May 2014. Status can change between updates, so confirm with the study contact before making plans.

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 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 was stopped early (reason given: The objective response rate by more than two people are confirmed.). Results are not available in the source record.

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?

Response rate (time frame: 1year 6months). 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 21 May 2014.
