- Has received prior therapy with an anti-programmed cell death protein 1 (anti-PD-1), anti-programmed cell death-ligand 1 (anti-PD-L1), or anti-PD-L2 agent or with an agent directed to another co-inhibitory T-cell receptor (i.e., cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], OX-40, CD137 [tumor necrosis factor receptor superfamily member 9 (TNFRSF9)]) or has previously participated in a Merck pembrolizumab (MK-3475) clinical trial.
- Has received prior anticancer therapy, monoclonal antibody, chemotherapy, or an investigational agent or device within 4 weeks or 5 half-lives (whichever is longer) before first dose of study treatment or not recovered (i.e., must be ≤ Grade 1 or at Baseline) from AEs due to previously administered agents.
- Has received a live vaccine within 30 days prior to the first dose of study treatment.
- Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study treatment.
A Randomized, Phase 3, Double-blind, Placebo-controlled Study of Pazopanib With or Without Abexinostat in Patients With Locally Advanced or Metastatic Renal Cell Carcinoma
Treatment Agent: Abexinostat
Synopsis: The purpose of this study is to compare the safety and effectiveness of pazopanib plus abexinostat to that of pazopanib plus placebo. This will be accomplished by monitoring how your disease is progressing. To do this, the study doctor and staff will assess how the disease affects your ability to complete daily living activities, test your blood for levels of thyroid hormone and liver enzymes; review results from scans of your tumor(s) and electrocardiogram (ECG) tests (painless, non-invasive tests that show how your heart works); and monitor your general health and vital signs. There will also be a test to find out how much of the medication is in your blood.
Abexinostat has been used in 16 other experimental studies that the Sponsor has conducted. Altogether, 487 people have been exposed either to abexinostat alone or to abexinostat combined with other treatments. One completed study used the same drugs that will be used in this study: abexinostat and pazopanib. The study was done in patients with renal cell carcinoma and it was found that the drugs were tolerated well.
This is a study to find out whether the investigational new drug, abexinostat, will improve the effects of pazopanib (the approved drug) in treating renal cell carcinoma. Because we do not know if abexinostat will improve the effects of pazopanib in treating renal cell carcinoma, we need to compare pazopanib plus abexinostat and pazopanib plus placebo. Participants with renal cell carcinoma who agree to be in this study will take pazopanib and either tablets containing abexinostat or placebo. A placebo is a tablet that does not contain active study medication(s).

- Patients have histologically confirmed RCC with clear cell component.
- Patients have locally advanced and unresectable or metastatic disease.
- Measurable disease as assessed only by the investigator (not verified by IRC) according to RECIST version 1.1.
- Patients must not have had any prior vascular endothelial growth factor (VEGF) tyrosine kinase inhibitor treatment in either (neo)adjuvant or locally advanced/metastatic setting. Up to 1 line of prior cytokine or immune checkpoint inhibitor treatment is allowed in either the (neo)adjuvant or metastatic setting provided screening scans indicate progressive disease (PD) during or following completion of treatment.

- Has persistent clinically significant toxicities (Grade ≥ 2; per NCI CTCAE version 5 from previous anticancer therapy (excluding alopecia which is permitted and excluding Grades 2 and 3 laboratory abnormalities if they are not associated with symptoms, are not considered clinically significant by the investigator, and can be managed with available medical therapies).
- Has untreated central nervous system (CNS) metastases. Patients with treated CNS metastases are eligible provided imaging demonstrates no new or progressive metastases obtained at least 4 weeks following completion of treatment. CNS imaging during Screening is not required unless clinically indicated.
- Has an additional malignancy requiring treatment within the past 3 years. Patients with the following concomitant neoplastic diagnoses are eligible: non-melanoma skin cancer, carcinoma in situ, and non-muscle invasive urothelial carcinoma.
- Poorly controlled hypertension, defined as systolic blood pressure ≥ 160 or diastolic blood pressure ≥ 100 mmHg. Use of anti-hypertensives and rescreening is permitted.
