Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
For phase 1: Participants must have received at least 1 prior line of systemic therapy for KS with either plateau in response, progressive disease, or inadequate response to treatment. Previous local therapy or radiation is not considered systemic therapy
For participants with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
Must not have
Pregnant persons are excluded from this study because abemaciclib is CDK inhibitor with the potential for teratogenic or abortifacient effects
No active KSHV-associated multicentric Castleman disease, KSHV-associated inflammatory cytokine syndrome or primary effusion lymphoma
Timeline
Screening 3 weeks
Treatment Varies
Follow Up every 3 cycles until completion of therapy, then every 3 months for 6 months, then every 6 months for 2 years, then annually for 2 years

Summary

This trial is studying a drug called abemaciclib to see if it can help treat people with Kaposi sarcoma.

Who is the study for?
Adults over 18 with Kaposi Sarcoma (KS), either HIV-positive on effective therapy or HIV-negative, can join. They must have tried at least one KS treatment without success for phase 1, or not received any systemic therapy for phase 2b. Participants need good organ and marrow function, no severe infections, controlled hepatitis if present, and agree to use contraception.
What is being tested?
The trial is testing Abemaciclib's safety and effectiveness in shrinking KS tumors. It involves taking the drug orally every day in cycles of 28 days until cancer progression or unacceptable side effects occur. The study includes regular health checks, lesion assessments, quality of life questionnaires, and follow-ups for up to two years post-treatment.
What are the potential side effects?
Abemaciclib may cause side effects such as fatigue; low white blood cell counts which can lead to infection risk; nausea; diarrhea; hair loss except alopecia or neuropathy that persists after other treatments; potential harm to a fetus so pregnant women are excluded.
