| Eligibility |
- INCLUSION CRITERIA:
- Patients must have histologically confirmed Kaposi sarcoma (KS) confirmed by the
Laboratory of Pathology, NCI.
- All patients should have either five measurable cutaneous KS lesions with no previous
local radiation, surgical or intralesional cytotoxic therapy that would prevent
response assessment for that lesion; or other assessable disease
- Group I: KS requiring systemic therapy (no prior therapy required) and:
- Group I patients should have one or more of the following:
- T1 KS, KS on skin sufficiently widespread that it is not amenable to local
therapy, or KS affecting quality of life due to local symptoms or psychological
distress
- KS patients with an inadequate response to pomalidomide (either progressive
disease or stable disease requiring additional therapy after 4 months)
- KS patients with an inadequate response to liposomal doxorubicin, paclitaxel, or
other systemic chemotherapy (either progressive disease or stable disease
requiring additional therapy after 6 cycles)
- Group I will exclude patients eligible for Group II (below). Patients with a
history of multicentric Castleman disease (MCD) in the absence of any active
disease (as assessed by the PI) are eligible for Group I.
- A wash out period off treatment of 3 weeks will be required, except in the
case of patients with progressive, severe disease in which delay of
treatment cannot be justified (i.e. symptomatic pulmonary KS)
- Group II: KS (no prior therapy required):
- Concurrent active KSHV-associated multicentric Castleman disease (MCD)
- Active KSHV Inflammatory Cytokine Syndrome (KICS), including those also meeting
clinical criteria for KS immune reconstitution syndrome (KS IRIS)
- At least five measurable cutaneous KS lesions with no previous local radiation,
surgical or intralesional cytotoxic therapy that would prevent response assessment for
that lesion; or other assessable disease
- ECOG Performance Status (PS):
- Group I: less than or equal to 2
- Group II: less than or equal to 3
- ECOG PS of 4 will be allowed in Group II only if symptoms due to pulmonary KS.
(with Karnofsky = 20%).
- Measurable disease by the criteria proposed by the AIDS Clinical Trials Group Oncology
Committee (for KS).
- Patients can be HIV positive or negative.
- HAART for HIV+ patients:
- All HIV+ patients must be willing to be compliant with HAART
- Group I-on HAART for 1 month with stable disease; however, no minimum time
restriction for patients with progressive and/or end-organ threatening disease
- Group II-no minimum time restriction on prior HAART, patients may be HAART naive.
- Age greater than or equal to 18 years.
--Because no dosing or adverse event data are currently available on the use of
pomalidomide in combination with liposomal doxorubicin in patients <18 years of age,
children are excluded from this study, but may be eligible for future pediatric
trials.
- Patients must have normal organ and marrow function as defined below:
- Absolute neutrophil count greater than or equal to 1,000/mcL
- Platelets >75,000/mcL
- Hemoglobin
- Group I: greater than or equal to 8 gm/dL;
- Group II: if anemia attributed to KS, KSHV-MCD, or KICS greater than or
equal to 7gm/dL, otherwise greater than or equal to 8 gm/dL
- Total bilirubin less than or equal to1.5 upper limit of normal unless the patient
is receiving a protease inhibitor known to be associated with increased bilirubin
(e.g. atazanavir), in which case total bilirubin less than or equal to 7.5 mg/dL
with direct fraction less than or equal to 0.7
- AST(SGOT)/ALT(SGPT) less than or equal to 2.5 X institutional upper limit of
normal
- Creatinine within normal institutional limits OR Creatinine clearance >60
mL/min/1.73 m(2) as estimated by either Cockroft-Gault or 24-hour urine
collection for patients with creatinine levels above institutional normal
- Cardiac ejection fraction greater than or equal to 50% by echocardiogram
- Patients with a cumulative lifetime history of anthracycline greater than 430 mg/m(2)
are eligible, after consultation with a cardiologist, if there are none of the
following cardiac risk factors:
- Diabetes mellitus
- History of acute coronary syndrome
- Hypertension; defined as a sustained systolic blood pressure greater than 140
mmHg and/or diastolic blood pressure greater than 90 mmHg OR use of an
antihypertensive medication for the indication of hypertension.
- All study participants must agree to be registered into the mandatory POMALYST REMS
program, and be willing and able to comply with the requirements of the POMALYST REMS
program
- Females of reproductive potential must adhere to the scheduled pregnancy testing as
required in the POMALYST REMSTM program
- Able to take aspirin 81mg daily or if intolerant of aspirin, able to take a substitute
thromboprophylaxis such as low molecular weight heparin at a thromboprophylactic dose
(such as enoxaparin 0.5mg/kg once daily)
- Because pomalidomide is an agent with the potential for teratogenic or abortifacient
effects, females of childbearing potential (FCBP) must have a negative serum or urine
pregnancy test with a sensitivity of at least 25 mIU/mL within 14 days prior to and
again within 24 hours before starting pomalidomide and must either commit to continued
abstinence from heterosexual intercourse or begin TWO acceptable methods of birth
control, one highly effective method and one additional effective method AT THE SAME
TIME, at least 28 days before she starts taking pomalidomide. FCBP must also agree to
ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact
with a FCBP even if they have had a vasectomy. All subjects must be counseled at a
minimum of every 28 days about pregnancy precautions and risks of fetal exposure.
- Ability of subject to understand and the willingness to sign a written informed
consent document.
EXCLUSION CRITERIA:
- Patients who are receiving any other investigational agents.
- Patients with primary effusion lymphoma or other concurrent malignancy, except for
basal cell carcinoma or squamous carcinoma of the skin or in situ cervical or anal
dysplasia
- History of malignant tumors other than KS or KSHV-MCD, unless:
- In complete remission for greater than or equal to 1 year for the time complete
remission was first documented
- Resected basal cell or squamous cell carcinoma of the skin
- In situ cervical or anal dysplasia
- Uncontrolled intercurrent illness including, but not limited to, uncontrolled active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements
- History of allergic reactions attributed to thalidomide, lenalidomide, or other
compounds of similar chemical or biologic composition to pomalidomide or other agents
used in study
- Because there is an unknown but potential risk for adverse events in nursing infants
secondary to treatment of the mother with pomalidomide, breastfeeding should be
discontinued if the mother is treated with pomalidomide. These potential risks may
also
apply to other agents used in this study.
