Summary:

      The main objective of this study is to investigate whether administration of maintenance
      temozolomide following standard treatment could possibly prevent or delay the onset of brain
      metastases in patients with controlled non-small cell lung cancer (NSCLC).
    

Eligibility criteria:

        Inclusion Criteria:

          -  Adult subjects (age >=18 years), of either sex, and of any race.

          -  Subjects must have stage IV or III with pleural and/or pericardial effusion

        histologically confirmed NSCLC.

          -  Subjects must have completed 2-6 cycles of a standard systemic therapy, with or
             without radiation therapy, consisting of at least 2 anti-tumor agents as first-line
             treatment for Stage III/IV disease, and have documented complete response (CR),
             partial response (PR), or stable disease (SD) per Response Evaluation Criteria in
             Solid Tumors (RECIST).

          -  Response must be confirmed within 4-8 weeks of completing first-line chemotherapy.
             Study treatment must begin within 12 weeks of completing first-line chemotherapy.

          -  Female subjects of childbearing potential or male subjects with female partner of
             childbearing potential must agree to use a medically accepted method of contraception
             or be surgically sterilized prior to Screening, while receiving study drug, and for 30
             days after stopping study drug. Female subjects of childbearing potential must have a
             negative pregnancy test confirmed prior to dosing with study drug.

          -  Subjects must be free of any clinically relevant disease (other than stage III/IV
             NSCLC) that would, in the principal investigator and/or Sponsor's opinion, interfere
             with the conduct of the study or study evaluations.

          -  Subjects must be able to adhere to the dosing and visit schedules, and agree to report
             medication taken, concomitant medications, and adverse events (AEs).

          -  Eastern Cooperative Oncology Group (ECOG) performance status <=2.

          -  Clinical laboratory tests (complete blood count [CBC], serum chemistries) must be
             obtained within 14 days prior to randomization and meet specified criteria.

        Exclusion Criteria:

          -  Brain metastases documented on post-chemotherapy magnetic resonance imaging (MRI).

          -  Documented history of brain metastases.

          -  Subject has received more than one prior anti-tumor regimen for Stage III/IV disease.
             "Regimen" refers to single drug or planned combination of two or more anti-tumor
             therapies. Bevacizumab (Avastin®) as part of a planned sequence of therapy after
             first-line platinum-containing double regimen is not considered a second regimen.
             Neo-adjuvant treatment for resectable subjects is not considered a second regimen.

          -  Subject has used any investigational product within 4 weeks prior to enrollment.

          -  Subject is currently receiving immunotherapy or chemotherapy, cytotoxic or targeted
             therapy as treatment for active systemic disease. Bevacizumab (Avastin®) as part of
             the prescribed standard first-line regimen is allowed.

          -  Female who is pregnant, or intends to become pregnant, during the study.

          -  Subject is in a situation or condition that, in the opinion of the investigator, may
             interfere with optimal participation in the study.

          -  Subject is currently participating in any other clinical study, with the exception of
             observational long-term follow-up.

          -  Subject is allergic to, or has sensitivity to, the study drug or its excipients.

          -  Documented symptomatic, progressive or new bone metastases following the first-line
             chemotherapy with or without radiation therapy (biphosphonate use for prophylaxis or
             as a maintenance therapy is allowed).

          -  No prior malignancy except for adequately treated basal cell or squamous cell skin
             cancer, in situ cervical cancer, or other cancer for which the subject has been
             disease-free for 5 years.
