Brief Summary:

This study seeks to enroll patients with AL amyloidosis, for whom treatment with one of the standard melphalan chemotherapy-based regimens is either not recommended or is not their preference.

Pomalidomide (CC-4047) is a drug given by mouth, which can change or regulate the functioning of the immune system. So, in theory, it may reduce or prevent the production of the amyloid protein. Pomalidomide is not currently FDA-approved for AL Amyloidosis. Pomalidomide is chemically similar to thalidomide and lenalidomide, both of these drugs have been approved by the FDA for treatment of patients with multiple myeloma (MM), a disease similar to AL Amyloidosis.

Participants in this study will receive pomalidomide and dexamethasone. Phase I is a dose-escalation study and dose escalation will proceed through 3 dose-levels according to standard rules in which dose levels are started sequentially after complete evaluation of the occurrence of dose-limiting toxicities. In the Phase II portion, participants will receive pomalidomide and dexamethasone using the defined maximum tolerated dose.

Condition or disease Intervention/treatment Phase
AL Amyloidosis Drug: Pomalidomide Drug: Dexamethasone Phase 1 Phase 2

Detailed Description:

Primary objective:

Determine dose-limiting toxicity (DLT) and the maximal tolerated dose (MTD) of pomalidomide combined with dexamethasone in subjects with previously- treated light-chain (AL)-amyloidosis

Secondary objectives:

Determine the following at the MTD:

  • Hematological complete (CR) very good partial (VGPR) and partial (PR) rates
  • duration of response
  • organ response
  • Time-to-event
  • Survival

Exploratory study objective:

To investigate the relationship of changes in the levels of the biomarkers B-type natriuretic peptide (BNP) and troponin I to frequency of specific adverse events and the occurrence of DLT

    2. Plasmacytosis of bone marrow (<30% plasma cells) with monoclonal staining for kappa or lambda light-chain isotype
    3. dFLC of 50mg/L (dFLC=difference in involved and uninvolved serum free light-chain levels)
  7. Must have received ≥1 prior treatment for AL amyloidosis, if it is intensive chemotherapy and an autotransplant it must be ≥6 months prior to enrollment on this study
  8. Must have recovered from the reversible side effects of any prior therapy; permanent and stable side effects/changes are acceptable. Prior treatment for AL amyloidosis with chemotherapy, thalidomide, lenalidomide or steroids is not an exclusion
  9. Eastern Cooperative Group (ECOG) performance status ≤2 at study entry
  10. Lab test results within these ranges:

    d. Neutrophil ≥1.5 x10e9/L e. Platelets ≥100x10e9/L f. Total bilirubin <1.5mg/dL g. Aspartate aminotransferase (AST or SGOT) and Alanine Aminotransferase (ALT or SGPT) < 2 x Upper limit of normal h. Serum creatinine <2.5mg/dL

  11. Disease free of prior malignancies for at least 5yrs with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma "in-situ" of the cervix or breast.
  12. Females of childbearing potential (FCBP) (a FCBP is a sexually mature woman who has not undergone a hysterectomy or bilateral oophorectomy, or has not been naturally postmenopausal for at least 24 consecutive months) must have a negative serum or urine pregnancy test with a sensitivity ≥ 50 milli-International unit/mL 10-14 days prior to and again ≤ 24 hours of starting pomalidomide and must either commit to continued abstinence from heterosexual intercourse or begin two (2) acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, ≥ 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.
