About this trial
The researchers are doing this study to find out whether the combination of abemaciclib and cabozantinib is a safe and effective treatment for people with metastatic clear cell renal cell carcinoma (ccRCC) and translocation-associated renal cell cancer (tRCC). The researchers will test different doses of the study drugs to find the highest doses that cause few or mild side effects in participants.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age ≥ 18 years at the time of informed consent
Patient must be able to provide informed consent, or a legal authorized representative (LAR) must be identified to provide consent in cases where the patient cannot
Signed and dated IRB-approved Informed Consent Form
Patient must have a histologically confirmed diagnosis of metastatic stage IV clear cell renal cell carcinoma or metastatic stage IV translocation-associated renal cell carcinoma.
Disqualifiers
Prior treatment with abemaciclib or cabozantinib.
Receipt of any type of anti-cancer antibody, cytotoxic anticancer therapy, or any other investigational agents within 2 weeks of treatment start or 5 half-lives, whichever is shorter. For immune checkpoint inhibitors, patients must have discontinued treatment 28 days prior to trial enrollment.
Symptomatic brain metastasis or leptomeningeal disease requiring steroid use. Patients are eligible if they are neurologically stable for 4 weeks, have completed radiation therapy or surgery, and recovered from side effects. Patients must have discontinued steroid therapy for at least 2 weeks prior to first dose of study treatment.
Diagnosis of another malignancy within 2 years before first dose of study treatment, except for superficial skin cancers, or early stage cancers previously treated with curative intent.

Trial outcomes
Primary outcomes
Maximally Tolerated Dose (MTD) (Phase Ib)
The phase 1b portion of the trial will require between 4 and 24 patients in a 3+3 dose escalation design across four planned separate dose levels. The MTD will be defined as the dose level at which a dose limiting toxicity (DLT) occurs in at most 1 out of 6 patients in that dose level. CTCAE v5.0 will be used for toxicity evaluation.
Secondary outcomes
Objective Response Rate (ORR) (Phase II)
per RECIST 1.1 for abemaciclib plus cabozantinib
