Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

- - Female subjects of childbearing potential must have a negative serum pregnancy test at screening.
- - The patient must be ≥18 years old - Capable of understanding and complying with the protocol and has signed the informed consent document.
- - Able to swallow study drug.
- - Sexually active patients (male and female) must use medically acceptable methods of contraception during the course of the study and for 3 months after completion of study treatment.
- - Confirmed availability of formalin-fixed, paraffin-embedded (FFPE) tumor tissue - Patients with tumor that is felt to be accessible to biopsy must be willing to provide tissue from a newly obtained core biopsy of a tumor lesion at baseline.
- - Received a prior CDK4/6 inhibitor.
- - Undergone major surgery within 14 days of the initial dose of study drug - Received another investigational agent (defined as any agent/device that has not received regulatory approval for any indication) within 14 days of the first dose of study drug for a nonmyelosupressive agent, or 21 days of the first dose of study drug for a myelosuppressive agent.
- - Has any severe concurrent disease, infection, or comorbid condition that renders the patient inappropriate for enrollment in the opinion of the investigator.
- - Has an active bacterial, fungal, and/or known viral infection.
- - Documented brain metastases that are untreated, symptomatic, or require therapy to control symptoms.
- - Any corticosteroid use for brain metastases must have been discontinued without the subsequent appearance of symptoms for ≥2 weeks before the first study drug.
- - Treatment for brain metastases may have included whole brain radiotherapy, radiosurgery, or a combination as was deemed appropriate by the treating physician.
- - Patients who meet the above criteria and are clinically stable on anti-convulsant medication are eligible only if their anti-convulsant does not alter hepatic cytochrome P450 activity in a way that might interfere with metabolism of abemaciclib.
- - Pregnant women are excluded from this study because of the potential for teratogenic effects.
- - Lactating women are excluding from the study.
- - Individuals with a history of a second malignancy are ineligible except for the following circumstances: individuals with a history of other malignancies are eligible if they have been disease-free for at least 5 years and are deemed by the investigator to be at low risk for recurrence of that malignancy.
- - Have received any live vaccination within 28 days of first dose of study drug.
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied. The FDA (the U.S. Food and Drug Administration) has not approved abemaciclib as a treatment for any disease. Some triple-negative breast cancers show expression of the Rb protein and are referred to as "Rb-positive." The Rb protein is important because it controls the way that cancer cells divide and grow. Drugs like abemaciclib work by changing the way that Rb functions. This can potentially stop cancer cells from dividing, and can also potentially lead to cancer cell death. In this research study, the investigators are are looking to see how safe abemaciclib is and how well it will work to help people with triple-negative breast cancer that is Rb-positive.
-Abemaciclib will be administered orally, twice daily on days 1 to 28
Drug: - Abemaciclib
Abemaciclib (LY2835219) has been shown in vitro to be a selective ATP-competitive inhibitor of CDK4 and CDK6 kinase activity that prevents the phosphorylation and subsequent inactivation of the Rb tumor suppressor protein, thereby inducing G1 cell cycle arrest and inhibition of cell proliferation.
