Brief Summary:
This is an open-label, two-arm, multicenter feasibility study to evaluate the safety and tolerability of pazopanib in combination with carboplatin and paclitaxel in female subjects with newly diagnosed advanced gynaecological tumors. Subjects will have received no prior therapy for their disease. A minimum of 12 and a maximum of 46 subjects will be enrolled. Dose schemas for each study arm are described in the protocol. For each arm, six subjects will be evaluated in treatment cohorts, which will be expanded to 20 subjects if initial toxicity is acceptable. Overall safety and tolerability of the regimen will be based on dose limiting toxicities, adverse events, and percentage of subjects that complete 6 courses of study treatment. Antitumor activity will be assessed using RECIST criteria and cancer antigen 125 (CA-125) responses.

Actual Study Completion Date : April 2008

Arm Intervention/treatment
Experimental: Arm A
Oral Pazopanib 800 mg once a day+ carboplatin area under the concentration-time curve (AUC) 5 intravenous (IV) over 1 hour every 3 weeks + paclitaxel 175 mg/m^2 IV over three hours day one q 3 weeks for six cycles
Drug: pazopanib (GW786034)
800 mg orally once a day for 6 cycles

Drug: carboplatin
IV over one hour every 3 weeks of 6 cycles

Drug: paclitaxel
IV 175 mg/m^2 given over 3 hours on day one of a 21 day cycle for six cycles

Experimental: Arm B
Oral Pazopanib 800 mg once a day+ carboplatin AUC 6 IV over 1 hour every 3 weeks + paclitaxel 175 mg/m^2 IV over three hours day one q 3 weeks for six cycles
Drug: pazopanib (GW786034)
800 mg orally once a day for 6 cycles

Primary Outcome Measures :
  1. Number of Participants Experiencing Serious Adverse Events and Non-serious Adverse Events [ Time Frame: Baseline to End of Study (up to a year) ]
    Safety and tolerability were measured by the number of participants with serious adverse events and non-serious adverse events. See the "Adverse Event" section of the results record for additional details and data.

Secondary Outcome Measures :
  1. Overall Response [ Time Frame: Baseline until either response or progression (up to 2 years) ]
    Although the study protocol specified several efficacy analyses, due to poor tolerability of the combination regimen and the consequent early withdrawal of most participants, which led to a small sample size, efficacy analyses were not performed. Overall response is defined as the number of participants with CR or PR per Response Evaluation Criteria In Solid Tumors (RECIST): CR, all detectable tumor has disappeared; PR, a >=30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum.

  2. Cancer Antigen (CA-125) Response [ Time Frame: Baseline until response (up to 2 years) ]
    Defined as the number of participants who achieved a confirmed CA-125 response, which is defined as at least a 50% reduction in CA-125 levels from a pre-treatment sample.

  3. 18-week Progression Free Survival [ Time Frame: Baseline to Week 18 ]
    Defined as the number participants who have not had radiological disease progression per RECIST, confirmed CA-125 progression, or death due to any cause by the end of 18 weeks.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Inclusion Criteria
  • A subject will be considered eligible for inclusion in this study only if all of the following criteria are met:
  • Subjects must provide written informed consent prior to performance of study specific procedures or assessments, and must be willing to comply with treatment and follow up.
  • Procedures conducted as a part of routine clinical management of the subject (e.g., blood count, imaging study) and obtained prior to signed informed consent may be utilized for Screening or Baseline purposes provided these tests are obtained as specified in the protocol).
  • Female subjects ≥18 years of age with newly diagnosed advanced gynaecological malignancies for whom carboplatin and paclitaxel based chemotherapy is indicated. Patients may have surgery to debulk or resect disease but may not have received chemotherapy or radiotherapy.
  • Histological confirmation of the following: epithelial ovarian cancer, endometrial carcinoma, uterine sarcoma, mixed Müllerian tumour, fallopian tube carcinoma, primary peritoneal carcinoma, cervical carcinoma or vulvar carcinoma.
  • Performance status must be ECOG 0 1.
  • Adequate organ system function as defined in Table 6
  • Table 6 Definitions for Adequate Organ Function
  • System (Laboratory Values)
  • Hematologic:
  • Absolute neutrophil count (ANC) (≥ 1.5 X 109/L)
  • Hemoglobin1 (≥9 g/dL)
  • Platelets (≥100 X 109/L)
  • International normalized ratio (INR)(≤ 1.2 X upper limit of normal (ULN))

  • Urine Protein to Creatinine Ratio2 (<1)
  • Patients may not have had a transfusion within 7 days of screening assessment.
  • If UPC ≥1, then a 24-hour urine protein must be assessed. Patients must have a 24-hour urine protein value <1g to be eligible.
  • Measurable or non-measurable disease.
  • A female subject is eligible to enter and participate in the study if she is:
  • Of non-childbearing potential (i.e., physiologically incapable of becoming pregnant) including any woman who:
  • Has had a hysterectomy, or
  • Has had a bilateral oophorectomy (ovariectomy), or
  • Has had a bilateral tubal ligation, or
  • Is post-menopausal
  • Subjects 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 (FSH) value >40 mIU/mL and an estradiol value < 40pg/mL (<140 pmol/L).
  • Subjects who are using hormone replacement therapy and whose menopausal status is in doubt will be required to use a highly effective method of contraception (as outlined in this inclusion criterion) if they wish to continue their HRT during the study. Otherwise, these subjects must discontinue HRT prior to study enrollment to allow confirmation of post menopausal status. For most forms of HRT, at least 2-4 weeks must elapse between the cessation of HRT and determination of menopausal status; length of this interval depends on the type and dosage of HRT. Following confirmation of post menopausal status, these subjects can resume HRT during the study without use of contraception.

  • An intrauterine device with a documented failure rate of less than 1% per year.
  • Vasectomized partner who is sterile 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 with spermicidal jelly, foam suppository, or film; diaphragm with spermicide; or male condom and diaphragm with spermicide).

Note: Oral contraceptives are not reliable due to potential drug-drug interactions.

  • Female subjects 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 14 days following the last dose of study drug.
  • Recovered from the effects of surgery.
  • Prior radiotherapy is permissible, provided at least 4 weeks have elapsed since the last treatment to allow for full bone marrow recovery.
