Phase 1
Active, not recruiting
Conditions
Prostatic Neoplasms
Interventions
Drug: LHRH agonist/antagonist
Registration Number
NCT05999968
Lead Sponsor
Eli Lilly and Company
Brief Summary

The main purpose of this study is to learn more about the safety and tolerability of abemaciclib when given in combination with darolutamide to participants with prostate cancer that has spread after initial treatment. Participation may last up to 32 months.

Target Recruitment
10
Inclusion Criteria
  • Histologically confirmed adenocarcinoma of the prostate.

  • Metastatic castration-resistant prostate cancer evidenced by:

    • Prostate-specific antigen (PSA) or radiographic progression despite castrate levels of testosterone
    • At least 1 bone metastasis on bone scan and/or 1 soft tissue metastasis on computed tomography/magnetic resonance imaging (CT/MRI)
  • Participants who have not undergone bilateral orchiectomy must continue luteinizing-hormone-releasing hormone (LHRH) agonists/antagonists throughout the study.

  • Have adequate organ function.

  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.

Exclusion Criteria
  • Prior treatment with cyclin-dependent kinase 4 and 6 (CDK4 and CDK6) inhibitors or darolutamide.
  • Prior systemic therapy for metastatic castration-resistant prostate cancer(mCRPC) with cytotoxic chemotherapy, PARP inhibitors, novel hormonal agents (NHAs) (enzalutamide, apalutamide, and abiraterone), and radiopharmaceuticals.
  • Serious preexisting medical condition(s) that, in the judgment of the investigator, would preclude participation in this study.
  • Clinically significant heart disease as evidenced by myocardial infarction, arterial thrombotic events, severe or unstable angina, or congestive heart failure (New York Heart Association Class III or IV) within 6 months of assignment to treatment.
