Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to test different doses of abemaciclib to find the best dose in participants while receiving hormone therapy and radiation therapy.

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion Criteria
* Aged ≥18 years at signing of informed consent. * Both male and female patients are allowed * Histologically confirmed metastatic breast cancer (mBC), current stage IV. * Plan for palliative radiotherapy to a bone metastasis. * Documented estrogen receptor (ER) positive and/or progesterone receptor (PgR) positive by immunohistochemistry. The threshold to qualify as ER or PgR positive is ≥1% per ASCO/CAP guidelines. * HER2 negative tumor status confirmed by immunohistochemistry or FISH per ASCO/CAP guidelines. * Any line of prior treatments (hormonal therapy and chemotherapy) is permitted including prior abemaciclib, palbociclib and ribociclib. * At the time of enrollment, treating physician has intent to resume abemaciclib (at any dose) following radiotherapy. * Patients who received chemotherapy must have recovered (Common Terminology Criteria for Adverse Events \[CTCAE\] Grade ≤1) from the acute effects of chemotherapy except for residual alopecia or Grade 2 peripheral neuropathy prior to enrollment. A washout period of at least 21 days is required between last chemotherapy dose and enrollment (provided the patient did not receive radiotherapy). * Patients who received radiotherapy must have completed and fully recovered from the acute effects of radiotherapy. A washout period of at least 14 days is required between end of radiotherapy and enrollment. No prior radiotherapy to the current intended target site is permitted (ie. reirradiation is excluded from this study). * The patient must be able to swallow oral medications. * The patient must have adequate organ function per the following criteria (as defined in Table 2): * Patient may remain on hormonal therapy and abemaciclib before enrollment. * Patients must discontinue other CDK4/6 inhibitor (palbociclib or ribociclib) for at least 7 days and recover from the acute effects of therapy (until the toxicity resolves to ≤Grade 1) except for residual alopecia and peripheral neuropathy. * Measurable or non-measurable disease is permitted as defined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1). * Patients must have an Eastern Cooperative Oncology Group (ECOG) status of ≤2 or Karnofsky Performance Status (KPS) ≥60. * Negative β-human chorionic gonadotropin (hCG) pregnancy test for premenopausal women of reproductive capacity (those who are biologically capable of having children) and for women less than 12 months after menopause. * Women of childbearing potential must agree and commit to the use of a highly effective method of contraception as determined to be acceptable by the investigator, from the time of informed consent until 28 days after the last dose of the investigational product. Men must agree and commit to use a barrier method of contraception while on treatment and for 4 weeks after last dose of investigational products. * Patients (or their legally authorized representative) must provide written, informed consent to participate in the study and follow the study procedures * At the discretion of the treating radiation oncologist, radiation to a metastatic bone lesion is indicated	* Bone lesions in the calvarium or spinal column are not eligible for the dose-finding or expansion portions of the study. * Patients currently enrolled in a clinical trial involving an investigational product or non-approved use of a drug or device (other than the study drug/device used in this study), or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study. * The patient has received an experimental treatment in a clinical trial within the last 30 days or 5 half-lives, whichever is longer, prior to the start of study intervention, or is currently enrolled in any other type of medical research (for example: medical device) judged by the sponsor not to be scientifically or medically compatible with this study. * Patients who received radiation therapy ≤14 days prior to initiation of investigational agents are excluded. * Patients are ineligible if they have serious and/or uncontrolled preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study (for example, interstitial lung disease, severe dyspnea at rest or requiring oxygen therapy, severe renal impairment \[e.g. estimated creatinine clearance \<30ml/min\], history of major surgical resection involving the stomach or small bowel, or preexisting Crohn's disease or ulcerative colitis or a preexisting chronic condition resulting in baseline Grade 2 or higher diarrhea). * Females who are pregnant or lactating. * The patient has active systemic bacterial infection (requiring intravenous \[IV\] antibiotics at time of initiating study treatment), fungal infection, or detectable viral infection (such as known human immunodeficiency virus positivity or with known active hepatitis B or C \[for example, hepatitis B surface antigen positive\]. Screening is not required for enrollment. * The patient has a personal history of any of the following conditions: syncope of cardiovascular etiology, ventricular arrhythmia of pathological origin (including, but not limited to, ventricular tachycardia and ventricular fibrillation), or sudden cardiac arrest. * Significant chronic gastrointestinal disorder with diarrhea as a major symptom (e.g., Crohn's disease, malabsorption, or Grade ≥2 diarrhea of any etiology screening). * Malignant spinal cord compression (ESCC2 or above) * Prior radiation therapy to the current target site.
