Study Details

Study Description

Brief Summary

This is an open-label, randomized, phase II study to evaluate the clinical activity of pembrolizumab in combination with pazopanib compared to pazopanib monotherapy.

Condition or Disease Intervention/Treatment Phase
  • Drug: pembrolizumab, pazopanib
Phase 2

Detailed Description

Pembrolizumab will be given for a maximum of 2 years i.e. a total of 35 cycles of pembrolizumab with the q3 week dosing. Participants who complete study intervention after 2 years of pembrolizumab can be treated with pazopanib monotherapy based on physician's judgement. The duration of optional pembrolizumab crossover treatment will be maximum of 2 years i.e. a total of 35 cycles of pembrolizumab for patients progressing on pazopanib.

  • International normalized ratio (INR) OR prothrombin time (PT) and activated partial thromboplastin time (aPTT) : ≤1.5 × ULN unless participant is receiving anticoagulant therapy as long as PT or aPTT is within therapeutic range of intended use of anticoagulants

  1. The participant (or legally acceptable representative if applicable) provides written informed consent for the trial.

  2. A male or female participant must agree to use a contraception as detailed in Appendix 2 of this protocol during the treatment period and for at least 120 days after the last dose of study treatment and refrain from donating sperm during this period.

  3. A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least one of the following conditions applies:

  4. Not a woman of childbearing potential (WOCBP) as defined in Appendix 2 OR

  5. A WOCBP who agrees to follow the contraceptive guidance in Appendix 2 during the treatment period and for at least 120 days after the last dose of study treatment.

  6. Archival tumor tissue sample or newly obtained [core, incisional or excisional] biopsy of a tumor lesion not previously irradiated has been provided. Formalin-fixed, paraffin embedded (FFPE) tissue blocks are preferred to slides. Newly obtained biopsies are preferred to archived tissue.

Exclusion Criteria:
  1. Receipt of the last dose of anticancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) 28 days prior to the first dose of study drug

  2. Any previous treatment with a PD1 or PD-L1 inhibitor, anti-PD-L2 agent, stimulatory/co-inhibitory T-cell receptor (eg. CTLA-4, OX-40, CD137), and/or pazopanib

  11. Has known active CNS metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are radiologically stable: without evidence of progression for at least 4 weeks by repeat imaging (note that the repeat imaging should be performed during study screening), clinically stable and without requirement of steroid treatment for at least 14 days prior to first dose of study intervention).

  12. Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment and is allowed.

  13. Has a history of or current(non-infectious) pneumonitis/interstitial lung disease that required steroids

  14. Has a known history of Human Immunodeficiency Virus (HIV) infection. Note: No HIV testing is required unless mandated by local health authority.

  15. Concurrent active Hepatitis B (defined as HBsAg positive and/or detectable HBV DNA) and Hepatitis C virus (defined as anti-HCV Ab positive and detectable HCV RNA) infection.

  • Note: Hepatitis B and C screening tests are not required unless:

  • Known history of HBV and HCV infection

  • As mandated by local health authority

  1. Known active infection requiring systemic therapy.
  • Active infection including tuberculosis

  • Active hepatitis B (HBsAg reactive and HBV DNA is detected)

  • Active hepatitis C (anti-HCV reactive and HCV RNA [qualitative] is detected)

  • Human immunodeficiency virus infection

  1. Is pregnant or breastfeeding or expecting to conceive or father children within the projected duration of the study, starting with the screening visit through 120 days after the last dose of trial treatment.

  2. Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients.

  3. Has had an allogenic tissue/solid organ transplant.

  4. Has a history or current evidence of any condition, therapy, or laboratory abnormality or other circumstance that might confound the results of the study, interfere with the participant's participation for the full duration of the study, such that it is not in the best interest of the participant to participate, in the opinion of the treating investigator.
