The purpose of this study is to determine the safety, tolerability, and maximal tolerated dose (MTD) of the combination of Abemaciclib and Sunitinib administered orally in patients with advanced and metastatic renal cell carcinoma. This study consists of two parts: Dose Escalation and Dose Expansion. During the dose escalation phase, participants will be sequentially enrolled in a standard 3 x 3 dose escalation study design to receive oral Abemaciclib in Combination with Sunitinib. The purpose of this dose escalation is to determine the maximal tolerated dose based on assessment of any dose limiting toxicity. The Dose Expansion Phase will enroll additional participants at the established maximal tolerated dose to further evaluate safety, tolerability, as well as the pharmacokinetics and pharmacodynamics of this combination drug regimen.


Renal cell carcinoma (RCC) accounted for about 64, 000 new cancer diagnoses in the USA in 2018. Up to 30% of those diagnoses will be patients with metastatic disease. Additionally, up to 50% of patients who undergo partial or radical nephrectomy will develop metastatic disease.. There is no cure for metastatic RCC, thus, metastatic RCC represents a significant cancer burden. Numerous directed therapies are available to improve overall survival but these do not result in durable complete responses. However, recent pre-clinical studies of RCC have demonstrated that Abemaciclib, a CDK4/6 and PIM1 kinase inhibitor, induces rapid, dramatic, and sustained tumor regression when used in combination with Sunitinib.

Our objectives for this study are as follows:

Primary Objectives:

  • Determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D) of the combination of Abemaciclib with Sunitinib for patients with metastatic renal cell carcinoma. Additionally, determine pharmacokinetics (serum trough levels) of Abemaciclib and Sunitinib at steady state.
  • Continued safety assessment of the combination of Abemaciclib and Sunitinib at the established maximum tolerated dose (i.e. the recommended Phase II dose)

Secondary Objectives:

Determine any anti-tumor activity in the dose expansion phase of the study. Tumor related activity will be assessed by:

  • Length of progression free survival
  • Disease response rate
  • Time to disease response
  • Disease control rate
  • Duration of response
  • Overall survival and progression free survival

Yes No Not Sure

Inclusion Criteria

Is your age greater than or equal to 18 yrs?
Gender: Male or Female
Do you have Renal Cell Carcinoma Metastatic?
Do you have any of these conditions: Do you have Renal Cell Carcinoma Metastatic??
Do you have any of these conditions: Do you have Renal Cell Carcinoma Metastatic??
Do you have any of these conditions: Do you have Renal Cell Carcinoma Metastatic??
Has histologic or cytologic evidence of metastatic renal cell carcinoma with histology predominantly (>50%) clear cell renal cell carcinoma solid neoplasm
Has evidence of metastatic disease. Intermediate and poor risk patients according to International Metastatic Renal Cell Carcinoma Database criteria (IMDC) must have received prior combination ipilimumab and nivolumab therapy and subsequently experienced disease progression, or been offered ipilimumab and nivolumab combination therapy and refused, or be ineligible for combination ipilimumab and nivolumab therapy. Patients with favorable risk disease have no eligibility requirement for prior use of ipilimumab and nivolumab immunotherapy
Intermediate and poor risk patients (according to IMDC criteria) must also have received prior cabozantinib therapy and subsequently experienced disease progression, or been offered cabozantinib therapy and refused, or be ineligible for cabozantinib therapy. Patients with favorable risk disease have no eligibility requirement for prior use of cabozantinib. Cytoreductive nephrectomy is allowed but not mandatory
Has in the opinion of the investigator, a predicted life expectancy of more than 3 months
Has presence of at least 1 lesion that is measurable or evaluable using RECIST v1.1. This is defined in at least one dimension as 20 mm with conventional techniques or as 10 mm with spiral CT, MRI or calipers by clinical exam
Has either archival tissue for analysis or will require confirmation of disease with fresh biopsy. Tissue will not be required pre/post treatment for biomarker analysis
Has an Eastern Cooperative Oncology Group (ECOG) performance score of 0, 1, or 2
Patients with central nervous system metastases must have received surgical and/or radiation treatment, the metastases must be neurologically stable, and patients must be off corticosteroids or receiving a stable low-dose regimen of corticosteroids (i.e., a daily dose of 10 mg or less of prednisone or equivalent) for at least 4 weeks prior to the first dose of study drug
Has completed any prior anticancer treatment and must have recovered from any acute toxicities. The period between the last dose of prior treatment and the first dose of study drug treatment must be at least 1 week for radiotherapy, at least 3-4 weeks from prior VEGFR/mTOR/ or immunotherapy or any other tyrosine kinase inhibitor (TKI) therapy, and at least 4 weeks for treatment with investigational drugs
Must be able to swallow capsules and tablets
Has adequate organ function (i.e. lung, liver, kidney, bone marrow), as evidenced by multiple laboratory value results within specific parameters
Women of childbearing potential (WOCP) as defined as not surgically sterile or not postmenopausal) must have a negative result for a serum pregnancy test before study drug administration on cycle 1 day 1. WOCP must use a medically accepted method of contraception and must agree to continue use this method for the duration of the study and for 30 days after discontinuation of study drug
If male, is surgically sterile, or, if capable of producing offspring, is currently using an approved method of birth control and agrees to continued use of this method for the duration of the study (and for 30 days after taking the last dose of study drug because of the possible effects on spermatogenesis)

Exclusion Criteria

Predominately non-clear cell renal cell carcinoma histology (i.e. >50%)
Has had chemotherapy within 4 weeks or radiotherapy within 1 week prior to first dose of study drug or those who have not recovered from toxicities due to agents administered more than 4 weeks earlier
Has ongoing or active infection requiring parenteral antibiotics
Has uncontrolled hypertension despite adequate therapy (i.e., systolic blood pressure higher than 150 mm Hg or diastolic blood pressure higher than 90 mm Hg found on 2 separate occasions separated by 1 week)
Has diabetes mellitus with occurrence of more than 2 episodes of ketoacidosis in the 12 months prior to the first dose of study drug
Has an active second malignancy other than curatively resected basal cell carcinoma of the skin, squamous cell carcinoma of the skin, in situ carcinoma of the cervix, or other cancers for which they are treated with curative intent, and no known active disease in the 3 years prior to enrollment
Has a primary brain tumor or has brain metastases from a non-renal cell cancer

Has a known history of pulmonary fibrosis or any other restrictive lung disorder
Has any other concurrent conditions including a medical, psychiatric, or social condition that, in the opinion of the investigator, could preclude the patient's participation in the study, pose an undue medical hazard, or interfere with the interpretation of the study results, including, but not limited to, patients with congestive heart failure (New York Heart Association [NYHA] Class III or IV), cardiac arrhythmia, or acute coronary syndromes within 6 months of enrollment
Has used an investigational drug within 4 weeks prior to first dose of study drug or is currently participating in another investigational study
