Phase 2 & 3
Waitlist Available
Research Sponsored by Eli Lilly and Company
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Progressive disease at study entry demonstrated during continuous androgen-deprivation therapy (ADT)/post orchiectomy defined as one or more of the following: PSA progression, Radiographic progression per Response Evaluation Criteria in Solid Tumors (RECIST)1.1 for soft tissue and/or per Prostate Cancer Working Group 3 (PCWG3) for bone, with or without PSA progression, Have adequate organ function, Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.
Metastatic prostate cancer documented by positive bone scan and/or measurable soft tissue metastatic lesions by CT or magnetic resonance imaging (MRI).
Must not have
Prior treatment with abemaciclib or any cyclin-dependent kinase (CDK) 4 & 6 inhibitors.
Gastrointestinal disorder affecting the absorption or ability to swallow large pills.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up baseline to date of death due to any cause (estimated up to 40 months)

Summary

This trial is testing a new combination of drugs for prostate cancer that has spread and is no longer responding to hormone therapy.

Who is the study for?
Men with advanced prostate cancer that has spread and is resistant to hormone therapy can join. They must have a specific type of prostate cancer confirmed by tests, worsening disease despite ongoing hormone treatment, and their body should be functioning well enough (ECOG 0-1). Men who've had certain other treatments or have serious heart, liver, or digestive problems cannot participate.
What is being tested?
The trial is testing the safety and effectiveness of adding abemaciclib to the standard treatment for this stage of prostate cancer: abiraterone acetate plus prednisone. Some participants will receive a placebo instead of abemaciclib to compare outcomes.
What are the potential side effects?
Abemaciclib may cause diarrhea, fatigue, nausea, low blood cell counts increasing infection risk; Abiraterone Acetate might lead to high blood pressure, fluid retention; Prednisone can cause weight gain, mood changes.
