Criteria
Inclusion Criteria:

- Cytopathologically or histologically confirmed dx of multiple myeloma

- Relapsed or refractory to the most recently received therapy.

- All pts must have received prior lenalidomide therapy and been determined to be
refractory, relapsed, or intolerant.

- Measurable disease, as indicated by one or more of the following:

Serum M-protein ≥ 0.5 g/dL Urine Bence Jones protein ≥ 200 mg/24 hr Elevated Free Light
Chain as per IMWG criteria, and abnormal ratio

- Pts must be ≥ 18 years of age

- Life expectancy of more than 3 months

- ECOG PS of 0-2

- Adequate hepatic function, with bilirubin < 2 times the upper limit of normal (ULN),
and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 times ULN

- Uric acid must be within laboratory normal range

- CrCl ≥ 50 mL/min

- Additional Laboratory Requirements ANC ≥1.0 x 109/L Hgb ≥8 g/dL(transfusion permitted)
Platelet count ≥50.0 x 109/L

- Screening ANC should be independent of granulocyte-and granulocyte/macrophage colony
stimulating factor (G-CSF and GM-CSF) support for at least 1 week and of pegylated
G-CSF for at least 2 weeks

- Pts may receive RBC or platelet transfusions, if clinically indicated, in accordance
with institutional guidelines

- Screening platelet count should be independent of platelet transfusions for at least 2
weeks.

- Written informed consent in accordance with federal, local, and institutional
guidelines

- FCBP must agree to ongoing pregnancy testing

- FCBP must have a negative serum or urine pregnancy test and agree to birth control.

- Male pts must agree to never have unprotected sexual contact with a female who can
become pregnant and must agree to either completely abstain from sexual contact with
females who are pregnant or are able to become pregnant. The patient must agree to
inform his physician if he has had unprotected sexual contact with a female who can
become pregnant or if he thinks for any reason that his sexual partner may be
pregnant.

- Male pts cannot donate semen or sperm while taking pomalidomide and for 28 days after
completing the study.

- All pts must be counseled at a minimum of every 28 days about pregnancy precautions
and risks of fetal exposure.

- Pts must agree to take enteric-coated aspirin 81 mg orally daily, or if history of
prior thrombotic disease, must be fully anticoagulated with warfarin (INR 2-3) or be
treated with full-dose, low molecular weight heparin, as if to treat deep venous
thrombosis (DVT)/pulmonary embolism (PE)at the investigator's discretion

Exclusion Criteria:

- Pts with known sensitivity to any immunomodulatory drugs (IMiDs)

- Use of any other experimental drug or therapy within 21 days prior to first dose

- Exposure to any prior chemotherapy, steroid use, or other myeloma treatment within 14
days prior to first dose. Pts currently on long term steroids do not require any
washout period. in addition, steroid use for spinal cord compression is permitted and
does not require a washout period.

- Radiation therapy within 14 days prior to first dose

- Known allergies to carfilzomib or Captisol

- POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and
skin changes)

- Current diagnosis of plasma cell leukemia

- Waldenström's macroglobulinemia

abnormalities uncontrolled by conventional intervention or myocardial infarction in
the previous six months prior to first dose.

the Investigator's discretion, may require active treatment or intervention for any
other malignancy within 8 months of starting study treatment.

- Serious psychiatric or medical conditions that could interfere with treatment

- Significant neuropathy (Grade 3, Grade 4, or Grade 2 with pain) at the time of the
first dose and/or within 14 days before enrollment

- Contraindication to any of the required concomitant drugs, including proton-pump
inhibitor (e.g. lansoprazole), enteric-coated aspirin or if a history of prior
thrombotic disease, warfarin or low molecular weight heparin

- Pts in whom the required program of oral and intravenous fluid hydration is
contraindicated, e.g. due to pre-existing pulmonary, cardiac, or renal impairment

- Pts with primary systemic amyloidosis

- Pts who have received prior treatment with carfilzomib (Phase II only)

- Pts who have received prior treatment with pomalidomide (Phase II only)

- Pts who have received prior treatment with both carfilzomib & pomalidomide (Phase I
only)
