A Phase I/II Trial of Pomalidomide and Dexamethasone in Subjects With Previously-Treated AL Amyloidosis

1. Understand and voluntarily sign informed consent form.

2. ≥18yrs old

3. Able to adhere to the study visit schedule and other protocol requirements.

4. Biopsy proven tissue amyloid deposits or positive fat aspirate

5. Proof of AL type (a or b)

6. Measurable plasma cell dyscrasia (a or b and c of the following required):

1. Monoclonal protein in the serum or urine by immunofixation electrophoresis

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.

13. Able to take aspirin (81 or 325 mg) daily as prophylactic anticoagulation (subjects intolerant to aspirin may use warfarin or low molecular weight heparin).
