Adjuvant Pazopanib in Stage I NSCLC

The aim of this study is to evaluate the efficacy and safety of pazopanib compared with placebo in patients with T \< or = 5 cm, N0 (stage I according to TNM 2009) completely resected NSCLC.

The study will be conducted in two phases as follows:

* The Phase II component of the study will be a randomized, double-blind, placebo-controlled, multi-centre study performed in France only. After undergoing NSCLC resection, 140 patients will be randomized to receive either pazopanib 400 mg per day or placebo for 24 weeks.
* The Phase III component of the study will be a randomized, double-blind, placebo-controlled, multi-centre study performed internationally. Patients who have completed the Phase II component of the study will be followed and included in the Phase III. Additional patients will also be recruited to a planned total of 355 patients per treatment arm. New patients will be randomized to receive either pazopanib 400 mg per day or placebo for 24 weeks.

    * Bilateral tubal ligation.
    * Or who is post-menopausal:
    * Patients not using hormone replacement therapy (HRT) must have experienced total cessation of menses for ≥1 year and be greater than 45 years in age, OR, in questionable cases, have a follicle stimulating hormone value \>40 mIU/mL and an estradiol value \<40 pg/mL (\<140 pmol/L).
    * Subject using HRT must have experienced total cessation of menses for ≥ 1 year and be greater than 45 years of age OR have had documented evidence of menopause based on FSH and estradiol concentrations prior to initiation of HRT.

    Childbearing potential, including any female who has had a negative serum pregnancy test within 1 week prior to the first dose of study treatment, preferably as close to the first dose as possible, and agrees to use adequate contraception. Contraceptive methods acceptable to the IFCT, when used consistently and in accordance with both the product label and the instructions of the physician, are as follow:
    * An intrauterine device with a documented failure rate of less than 1% per year.
    * Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry and is the sole sexual partner for that female.
    * Complete abstinence from sexual intercourse for 14 days before exposure to investigational product, through the dosing period, and for at least 21 days after the last dose of investigational product.
    * Double-barrier contraception : condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository)
    * Oral contraceptive, either combined or progestogen alone \[Hatcher, 2004\]
    * Injectable progestogen \[Hatcher, 2004\]
    * Implant of levonorgestrel \[Hatcher, 2004\]
    * Estrogenic vaginal ring \[Hatcher, 2004\]
    * Percutaneous contraceptive patches \[Hatcher, 2004\]

    Female patients who are lactating should discontinue nursing prior to the first dose of study drug and should refrain from nursing throughout the treatment period and for 15 days following the last dose of study drug.

    A male with a female partner of childbearing potential is eligible to enter and participate in the study if he uses a barrier method of contraception or abstinence during the study.

2. Presence of any concurrent disease or condition that would make the subject inappropriate for study participation including any unresolved or unstable, serious toxicity from prior administration of another investigational drug or any serious medical disorder that would interfere with the subject's safety, obtaining informed consent, or compliance with all study related procedures.
