Trial size 43 participants
Trial identifier NCT01566747, ICORG 10-01


This is a phase II open label, single arm study evaluating treatment with pazopanib post sunitinib treatment in 43 patients with metastatic renal cell carcinoma. Patients will receive 800mg pazopanib per day given continuously until disease progression. Patients must have received treatment with sunitinib and relapsed. Patient must have received prior treatment with sunitinib for at least 12 weeks. Prior treatment with either temsirolimus or everolimus in addition to sunitinib is allowed. The trial design uses a Simons two stage design with an interim analysis planned after the first 15 evaluable patients. If 8 or more of the first 15 evaluable patients remains disease free at 4 months, then a further 28 patients will be enrolled for a total of 43 metastatic renal cell cancer patients. It is estimated that there could be up to 10% of patients dropping out and so to achieve the required number of 43 evaluable patients the study will recruit up to 48 patients to ensure that 43 complete if stage 2 is required.

Patients will receive treatment until disease progression, unacceptable toxicity or withdrawal of patient consent. Response assessments will be carried out every 8 weeks until disease progression. Safety assessments will be carried out every 4 weeks (plus a visit for liver function tests after 2 weeks) for the first six months and then every eight weeks until disease progression. A further safety assessment will be carried out 4 weeks after treatment discontinuation.

Eligibility Criteria

Male or female participants at least 18 years old.

Inclusion Criteria: 1. 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 part of the subject's routine clinical management (e.g., blood count, imaging study) and obtained prior to signing of informed consent may be utilized for screening or baseline purposes provided these procedures are conducted as specified in the protocol. Note: It is not necessary that informed consent be obtained within the protocol-specified screening window. 2. Age ≥ 18 years 3. Diagnosis of metastatic/unresectable renal cell carcinoma of the clear cell type or with a component of clear cell histology 4. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 5. Measurable disease by RECIST criteria (Version 1.1) 6. Eligible patients must have been treated with sunitinib for a minimum of 12 weeks (2 cycles). Patients must have evidence of progressive disease following treatment with sunitinib as assessed by the site investigator on the basis of CT scans and other appropriate clinical documentation. Patients who received sunitinib for 12 weeks (2cycles) but stopped the drug due to toxicity rather than disease progression are also eligible for this study. The Investigator should be aware of the patient's intolerance/toxicity with prior sunitinib treatment and take this in to account when assessing eligibility for the pazopanib study. Patients who have had prior treatment with either temsirolimus or everolimus are also eligible for the trial. No other prior treatment with bevacizumab, sorafenib, immunotherapies, chemotherapy, biologic therapy or investigational therapy is allowed. Previous radiotherapy (RT) is permissible provided the measurable disease is outside the RT port. RT must be completed > 2 weeks prior to registration. 7.

Subjects 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 or urine 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.
