Adaptive Pembrolizumab and Axitinib for the Treatment of Advanced Clear Cell Renal Cell Carcinoma
This phase II trial studies how well adaptive treatment with pembrolizumab and axitinib works in treating patients with clear cell renal cell carcinoma (ccRCC) that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Typically, patients with advanced ccRCC are treated continuously regardless of whether tumor size is decreasing. During adaptive treatment, patients are closely monitored to see when the tumor size decreases. Once this happens, the combined drugs are stopped, and patients are closely monitored to see if the tumor size increases again, at which point the drugs are restarted. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib is in a class of medications called tyrosine kinase inhibitors. It interferes with cell communication and growth and may prevent tumor growth. Giving adaptive treatment with pembrolizumab and axitinib may be effective in treating advanced ccRCC.

Subjects requiring intermittent use of bronchodilators, inhaled steroids, or local steroid injections will not be excluded from the study. Subjects with hypothyroidism, or adrenal or pituitary insufficiency who are stable on hormone replacement will not be excluded from the study
- Has a known additional malignancy that has progressed or has required active treatment in the last 1 year. Note: Basal cell carcinoma of the skin, squamous cell carcinoma of the skin, superficial bladder cancer, or carcinoma in situ such as breast cancer in situ are acceptable if they have undergone potentially curative therapy
- Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are radiologically stable, i.e., 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 C1D1
- Has a history of (non-infectious) pneumonitis that required steroids in the past 6 months or current pneumonitis
- Has an active infection requiring systemic therapy
- Has a known history of human immunodeficiency virus (HIV) infection (e.g. HIV 1 and/or 2 antibodies), that is not well controlled

- 12-lead electrocardiogram (ECG) will be performed during screening. If the initial QT interval corrected by Fridericia's correction formula (QTcF) is found to be > 500 msec, two additional EKGs separated by at least 3 minutes should be performed. If the average of these three consecutive results for QTcF is ≤ 500 msec, the subject meets eligibility in this regard

PRIMARY OBJECTIVES:
I. Assess the acceptability of enrollment on an adaptive therapy approach.
II. Assess the median 12 months progression-free survival (PFS) rate of patients on adaptive therapy.
III. To assess the feasibility, acceptability and preliminary efficacy of a response-based multi-drug adaptive therapy approach with pembrolizumab-axitinib (pembro-axi) in patients with metastatic clear cell renal cell carcinoma (mccRCC).
IV. To evaluate patient reported outcomes, health care utilization, and healthcare costs of a response-based multi-drug adaptive therapy approach with pembro-axi in patients with mccRCC.
SECONDARY OBJECTIVES:
I. Assess the improvement of patient reported outcomes (PROs) of patients on adaptive therapy.
II. Assess the median progression-free survival (PFS) time of patients on adaptive therapy.
III. Assess the median overall survival (OS) time of patients on adaptive therapy.
IV. Assess the proportion of subjects with persistent disease control not requiring disease reinitiation for more than 12 months after therapy discontinuation.
V. Assess safety and toxicity.
VI. Assess intra-tumoral changes in radiomic properties as indicators of evolution, response, and resistance to treatment via traditional and novel radiomically defined habitats.
OUTLINE:
PEMBRO-AXI: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1 of each cycle and axitinib orally (PO) twice daily (BID) on days 1-21 of each cycle. Cycles repeat every 21 days for up to 3 cycles in the absence of disease progression or unacceptable toxicity. After completion of cycle 3, patients undergo disease response assessment with computed tomography (CT) or magnetic resonance imaging (MRI). Patients whose tumor has decreased in size by > 20% move to the observation phase. Patients whose tumor has not decreased in size by > 20% continue to receive pembro-axi every 21 days for up to 48 months in the absence of disease progression or unacceptable toxicity. Patients continue to undergo disease response assessment with CT or MRI every 9 weeks and move to the observation phase once tumor size has decreased by > 20%.
OBSERVATION PHASE: Patients undergo blood sample collection every 3 weeks and CT or MRI every 9 weeks. Patients whose tumor increases to its original size or more resume pembro-axi therapy as described above.
Patients undergo blood sample collection, and CT or MRI throughout the study and may optionally undergo biopsy on study. Patients may also undergo biopsy during screening.
After completion of study treatment, patients are followed up at 30 days and then every 6 months until death or 2 years after end of therapy visit, whichever comes first.
