Brief Summary:
In this study will be examined whether alternating treatment between two classes of drugs (TKI's and m-TOR inhibitors) postpones or prevents drug resistance in patients with renal cancer.

Condition or disease Intervention/treatment Phase
Clear Cell Renal Carcinoma Drug: Pazopanib Drug: Everolimus Phase 2

Detailed Description:

Current practice is to treat with VEGFR-TKI or mTOR inhibitors until progression and then continue with the next active agent. From a biological perspective, TKI's will most likely activate compensatory pathways which, may ultimately lead to the development of resistance. Recent studies suggest that resistance to treatment with TKI may be reversible after stopping treatment. There is therefore a rationale to alternate treatment to prevent or delay the occurrence of resistance.

Our hypothesis is that alternating active agents in clear cell renal carcinoma (ccRCC) may reduce side effects, improve tolerability and compliance of treatment and prolong progression free survival and overall survival compared to the standard of care.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Progression free survival [ Time Frame: Randomization until earliest date of disease progression (according RECIST 1.1 criteria) or death, an expected average of one year ]

Secondary Outcome Measures :
  1. Time to second progression [ Time Frame: Time between first and second progression, an expected average of five months ]
    Time between first progression and second progression (PD) per RECIST 1.1 on Everolimus monotherapy (when PD after 8 weeks Pazopanib) or Pazopanib monotherapy (when PD after 8 weeks Everolimus) as second line treatment in experimental arm and time to progressive disease on Everolimus as second line treatment in comparative arm.

  2. Change in Quality of life assessed by the FKSI-DRS and EORTC QLQ-C30 questionnaires compared to baseline [ Time Frame: From randomization until one month after ceasing study medication, an expected average of 18 months ]
    Quality of life will be assessed bi-monthly by using the FACT Kidney Symptom Index (FKSI)-Disease Related Symptom (DRS)and the EORTC QLQ-C30 questionnaire. The symptoms covered by the FKSI-DRS include fatigue, pain, weight loss, dyspnea, cough, fever and hematuria. The EORTC QLQ-C30 questionnaire evaluates five functional scales (physical, role, emotional, social and cognitive functioning), three symptom scales (fatigue, pain, nausea, and vomiting), a global health status/QoL scale, and six single items (dyspnea, diarrhea, constipation, anorexia, insomnia and financial impact).

  3. Toxicity reported as number/percentage of patients with adverse events [ Time Frame: From randomization until one month after ceasing study medication, an expected average of 18 months ]
    Adverse events will be reported according Criteria for Adverse Events v4.0 (NCI CTCAE v4)

  4. Overall survival [ Time Frame: Time between randomization and death, an estimated average of 2-5 years ]
