About this trial
Background:
Kaposi Sarcoma (KS) is common in people with human immunodeficiency virus (HIV) but can also occur in people who do not have HIV. KS tumors usually involve the skin, but may also involve lymph nodes, lungs, bone, and gastrointestinal tract. Researchers want to see if a drug that is currently used to treat a type of breast cancer can help.
Objective:
To find a safe dose of abemaciclib to treat KS and to see if it can shrink lesions or tumors.
Eligibility:
People ages 18 and older with KS.
Design:
Participants will be screened with some or all of the following:
Medical history
Physical exam
Blood and urine tests
Chest x-ray and/or computed tomography scans
Lung or gastrointestinal tract exam with an endoscope (a flexible instrument to examine the interior of the organ)
Medicine review
Heart function tests
KS lesion assessment
Skin sample from a KS lesion
Treatment will be given in 28-day cycles. Participants will take the study drug tablets by mouth everyday. They will keep a medicine diary. They will get the study drug until their cancer gets worse or they have unacceptable side effects. Participants who stopped taking abemaciclib because it was no longer providing additional benefit may be able to restart abemaciclib again.
Participants will have a study visit at the beginning of each cycle. At these visits, they will repeat some screening tests. They may have medical photographs taken of body surfaces. They may complete questionnaires about their quality of life. They may give skin and saliva samples. For skin samples, an area of skin will be numbed. A small circle of skin over an area affected by KS will be removed.
Participants will have follow-up visits for up to 2 years after treatment ends.
Eligibility criteria
Qualifiers
Participants must have Kaposi sarcoma confirmed by the Laboratory of Pathology, NCI
All participants in Groups 1, 2a, or 2b or 4 should have at least five measurable cutaneous KS lesions per AIDS Clinical Trials Group Oncology Committee (ACTG) criteria with no previous local radiation, surgical or intralesional cytotoxic therapy that would prevent response assessment for that lesion and/or evaluable disease per RECIST criteria.
Measurable disease by the criteria proposed by the AIDS Clinical Trials Group Oncology Committee.
Participants in Group 3 must have Stage T1 KS with at least five measurable cutaneous KS lesions per ACTG criteria and/or evaluable disease per RECIST criteria.
Disqualifiers
Participants who have had chemotherapy or immunotherapy within 3 weeks prior to entering the study.
Participants 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.
Participants who have not recovered from adverse events due to prior anti-cancer therapy (i.e., have residual toxicities > Grade 1) with the exception of alopecia or neuropathy.
Participants who are receiving any other investigational agents.
