Phase: Phase 2
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Parallel Assignment
Masking: None (Open Label)
Enrollment: 128.0
Sex: All

Healthy volunteers: No
Keywords: NSCLC; phase 2 study; TAS-114; S-1

Summary:

      This is a randomized, open-label, Phase 2 study of TAS-114 administered in combination with
      S-1, to investigate the efficacy, safety and tolerability of the TAS-114/S-1 regimen in
      patients with advanced or metastatic NSCLC.

      The study will be conducted internationally in 2 regions: Asian [Japan] and Western [Europe
      and US]. Patients will be randomized into TAS-114/S-1 arm versus S-1 control arm in a 1:1
      ratio.

             agree to use effective birth control during the study (prior to the first dose and for
             6 months after the last dose) if conception is possible during this interval.

         10. Willing and able to comply with required scheduled visits and study procedures.

          1. Treatment with any of the following within the specified time frame prior to the study
             drug administration:

               -  Major surgery within prior 4 weeks and minor surgery within 7 days;

               -  Radiotherapy for extended field within prior 4 weeks or limited field within
                  prior 2 weeks;

               -  Any anticancer therapy or investigational agent within prior 3 weeks.

          2. A serious illness or medical condition

          3. Concomitant treatment with the following drugs that may interact with S-1:

             Sorivudine, brivudine, uracil, eniluracil, folinate/folinic acid, Cimetidine,
             dipyridamole, and nitroimidazoles, including metronidazole and
             misonidazoleMethotrexate, Clozapine,Allopurinol,Phenytoin,Flucytosine, a fluorinated
             pyrimidine antifungal agent,Coumarin-derivative anticoagulant

          5. Previous use of TAS-114, S-1, and 5-FU drugs;

          6. A pregnant or lactating female or possibly pregnant women, or men or women wishing to
