Eligibility

Inclusion Criteria:

• A subject will be eligible for inclusion in this study only if all of the following criteria are met:

• Signed, written informed consent prior to performing any study-related procedures

• Female subjects =18 years of age

• FIGO Stage IVB, or recurrent or persistent cervical cancer

• Life expectancy of at least 12 weeks

• ECOG status of 0 or 1.

• Histologically confirmed FIGO Stage IVB, or recurrent or persistent squamous cell carcinoma, adenosquamous carcinoma, or adenocarcinoma of the cervix which is not amenable to curative treatment with surgery and/or radiation therapy

Each lesion must be = 20 mm when measured by conventional techniques, including palpitation, plain x-ray, CT and MRI, or =10 mm when measured by spiral CT.

• At least one "target lesion" to be used to assess response as defined by Response Evaluation Criteria in Solid Tumors (RECIST; Terasse, 2000). Tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy.

• Received 0 or 1 prior chemotherapy regimen for metastatic disease.

• Note: Chemotherapy given in combination with radiation therapy as a radiosensitizer does not count toward this prior therapy limit

• Recovered from the effects of surgery or chemotherapy. At least three weeks must have elapsed from the last administration of chemotherapy.

• Adequate organ and bone marrow function as defined in Table 1.

• Table 1:(Definitions for Adequate Organ Function)

• System:(Laboratory Values)

• Subjects may not have had a transfusion within 7 days of screening assessment.

• Calculated by Cockcroft Gault formula See Appendix 7: Renal Function Tests

• A patient should first be screened with dipstick urinalysis. If urine protein by dipstick analysis is =2+, then a 24-hour urine protein must be assessed and 24 hour urine protein must be <1 g protein to be eligible.

• Ability to swallow and retain oral medication.

• A female is eligible to enter and participate in this study if she is of:

• Non-childbearing potential (i.e., physiologically incapable of becoming pregnant), including any female who has had:

• A bilateral tubal ligation

• Is post-menopausal (total cessation of menses for = 1 year)

• Childbearing potential, has 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 follows:

• 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 investigation 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.

• 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 as outlined in the protocol. Procedures conducted as apart of routine clinical management of the patient (e.g., blood count, imaging study) and obtained prior to signed informed consent may be utilized for screening purposes provided these tests are obtained as specified in the protocol

Exclusion Criteria:

• A subject will not be eligible for inclusion in this study if any of the following criteria apply:

• Neuroendocrine or small cell carcinoma of the cervix.

• Prior use of any biologic therapy with VEGF, VEGFR, or ErbB1/ErbB2 inhibitors.

• Concurrent cancer therapy (chemotherapy, radiation therapy, surgery, immunotherapy, biologic therapy, hormonal therapy, and tumor embolization).

• Concurrent treatment with an investigational agent or participation in another clinical trial.

• Use of an investigational anti-cancer drug within 28 days or 5 half-lives, whichever is longer, preceding the first dose of study medication.

• Has taken or is taking prohibited medications listed in the protocol.

• Any serious and/or unstable pre-existing medical, psychiatric, or other conditions that could interfere with patient's safety, obtaining informed consent or compliance to the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-free Survival (PFS) in Interim Analysis	PFS is defined as the interval between the date of randomization and the date of disease progression or death due to any cause. The study was designed to test Combination vs. Lapatinib first. The result indicated that Combination would not show improvement over Lapatinib even if followed until the final analysis and the Combination arm was terminated. The monotherapy arms continued to the final analysis. Data shown here are from this interim analysis.	From randomization until at least 35 PFS events in pairwise comparison of the three treatment arms (Interim Analysis; up to 52.14 weeks)	No
Primary	Progression-free Survival (PFS) in Final Analysis	PFS is defined as the interval between the date of randomization and the date of disease progression or death due to any cause. This study began as a 3-arm study. The combination arm was terminated at the interim analysis. The monotherapy arms continued to final analysis. Data shown here are from the final analysis.	From Randomization until 105 total PFS events in combined population of two monotherapy arms (up to 85.57 weeks)	No
Secondary	Overall Survival	Overall survival is defined as the time from randomization until death due to any cause.	From Randomization (11 December 2006) until approximately 78% overall survival events at the time of the second overall survival update (3 March 2010) (up to 168.29 weeks)	No
Secondary	Clinical Benefit Response	Clinical benefit response is defined as the number of participants with evidence of complete (CR) or partial (PR) tumor response or stable disease (SD) for at least 6 months (183 days). 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; Stable Disease, small changes that do not meet previously given criteria. Confirmation requires at least 2 assessments of CR/PR with at least 4 weeks between assessments.	From Randomization until 105 total PFS events in combined population of two monotherapy arms (up to 85.57 weeks)	No
Secondary	Response	Response is defined as the number of participants achieving either a complete or partial tumor response per RECIST criteria. 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.	From Randomization until 105 total PFS events in combined population of two monotherapy arms (up to 85.57 weeks)	No
Secondary	Time to Response	For the subset of participants who showed a confirmed CR or PR, time to response was defined as the time from randomization until the first documented evidence of CR or PR (whichever status was recorded first). 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.	From Randomization until 105 total PFS events in combined population of two monotherapy arms (up to 85.57 weeks)	No
Secondary	Duration of Response	For participants who had a CR or PR, the duration of response was defined as the time from first documented evidence of PR or CR until the first documented sign of disease progression or death. 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.	From Randomization until 105 total PFS events in combined population of two monotherapy arms (up to 85.57 weeks)	No
Secondary	Safety and Tolerability of Pazopanib, Lapatinib and the Combination of Pazopanib and Lapatinib	Safety was assessed as the number of participants experiencing a serious adverse event (SAE) or an adverse event (AE). See the adverse event module for safety data.	From Randomization (11 December 2006) until last participant had last visit (28 July 2011) in combined population of two monotherapy arms (up to 241.43 weeks)	No
