Feasibility Study of Pazopanib in Combination With Chemotherapy in Gynaecological Tumors
Trial end date:
SummaryThis 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.
Accepts Healthy Volunteers?No
- 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)
- 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))
- Partial thromboplastin time (PTT) (≤1.2 X ULN)
p Total bilirubin (≤1.5 X upper limit of normal (ULN))
- AST and ALT (≤ 2.5 X ULN)
- Serum Creatinine (≤ 1.5 mg/dL)
- Or, if serum creatinine >1.5 mg/dL, (≥ 50 mL/min)
- Calculated creatinine clearance
- 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
- Childbearing potential, including any female who has had a negative serum pregnancy
test within 2 weeks prior to the first dose of study treatment, preferably as close to
the first dose as possible, and agrees to use adequate contraception. GSK acceptable
contraceptive methods, 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.
- 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.
- A subject will not be eligible for inclusion in this study if any of the following
- Prior use of anticancer therapy (except cytoreductive surgery [debulking]) for their
- Presence of bulky, residual, squamous cell tumors.
- Is unable to discontinue prohibited medications, as listed in Section 8.2 for 14 days

dosing, including but not limited to:
- Malabsorption syndrome

pressure medication is permitted prior to study entry provided the subject has 2
consecutive blood pressure readings less than 140/90 mmHg, each separated by a minimum
