Primary purpose: TREATMENT

Brief summary: The study will investigate the effects of adding carfilzomib to the combination of pomalidomide and dexamethasone in sequential dose escalation cohorts in patients with relapsed or refractory multiple myeloma. This portion of the study is complete.

This study will also investigate the effects of adding daratumumab to the combination of carfilzomib, pomalidomide and dexamethasone.

Detailed description: Patients receive carfilzomib, pomalidomide, and dexamethasone in 28 days treatment cycles. Study treatment continues for as long a their myeloma does not worsen and they do not have unacceptable side effects. After completion of study treatment, patients are followed for up to 2 years.

Eligibility criteria: Inclusion Criteria:

* Relapsed and relapsed/refractory multiple myeloma requiring systemic therapy
* Failed at least one prior treatment for multiple myeloma (must have received lenalidomide)

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

  * Serum M-protein \>= 0.5 g/dL
  * Urine M-protein \>= 200 mg/24 hours
  * If serum protein electrophoresis is felt to be unreliable for routine M-protein measurement, then quantitative immunoglobulin levels are acceptable
  * Involved serum free light chains ≥ 10 mg/dL (free light change ratio must be abnormal)
* Aged 18 years or older

* Must agree to practice abstinence or use two acceptable methods of birth control
* Men must agree to use latex condom during sexual contact with women of childbearing potential (even if post vasectomy)
* Must agree to adhere to all study requirements, visit schedule, outpatient treatment, required concomitant medications, and laboratory monitoring

* Any clinically significant medical disease or condition that, in the investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent
* Significant neuropathy (grades 3-4, or grade 2 with pain) at the time of the first dose and/or within 14 days before enrollment
* Contraindications to any of the required concomitant drugs, including proton-pump inhibitor (eg, lansoprazole), enteric-coated aspirin, allopurinol or if a history of prior thrombotic disease, warfarin or low molecular weight heparin
