This is a Phase I/II study using the combination of twice weekly ixazomib plus pomalidomide and dexamethasone in relapsed and or refractory multiple myeloma (RRMM) patients.


This is a Phase I/II clinical trial. A Phase I clinical trial tests the safety of an investigational drug and tries to define the appropriate dose of the investigational drug to use for further studies. "Investigational" means that the drug is being studied.

The FDA has approved both pomalidomide and ixazomib individually for the treatment of multiple myeloma. Dexamethasone, also FDA approved, is a type of steroid and is usually combined with other chemotherapy for the treatment of blood cancers, such as myeloma and leukemias.

  • Ixazomib targets a part of cells called proteasomes. It works by slowing down or blocking proteasomes from doing their job of digesting proteins. In myeloma cells, there is a greater need for proteasomes to digest proteins; the buildup of excess proteins causes cell death.
  • Pomalidomide has also been shown to cause tumor cell deaths. Dexamethasone can stop white blood cells from traveling to areas myeloma cells are causing damage. When combined with myeloma drugs, it sometimes makes those drugs work better.

In this research study, the investigators are:

  • Testing the safety of ixazomib when given with pomalidomide and dexamethasone
  • Pomalidomide and ixazomib are given individually for the treatment of multiple myeloma. Dexamethasone is also given for multiple myeloma
  • Ixazomib when combined with pomalidomide and dexamethasone may help control the disease
  • Ixazomib is FDA approved to treat multiple myeloma
  • The investigators are looking for the highest dose of ixazomib that can be given safely in combination with pomalidomide and dexamethasone

Inclusion Criteria

Patients with relapsed and relapsed refractory myeloma may be eligible for this trial of they meet all the following entry criteria
Previously diagnosed with MM based on standard IMWG criteria and currently requires treatment
Patient has given voluntary written informed consent before performance of any study-related procedures not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care
Patient had received at least two previous therapies OR received 1 prior line of therapy if previously treated with an IMiD plus a proteasome inhibitor and has demonstrated disease progression on or within 60 days of completion of the last therapy
Patient has measurable disease defined as at least one of the following according to Standard Diagnostic Criteria (Rajkumar 2014)
Serum IgG, IgA, or IgM M-protein 0.5 g/dL, or
Serum IgD M-protein 0.05 g/dL, or
Urine M protein 200 mg/24 hours or
Serum free light chain (FLC) assay: Involved FLC assay 10 mg/dL (100 mg/L) and an abnormal serum FLC ratio (<0.26 or >1.65)

Platelet count 75,000 cells/dL (75 x 109/L) (without transfusions required during the 14 days prior to initiation of therapy)
Hemoglobin 8.0 g/dl (RBC transfusions are permitted)
Total Bilirubin 1.5 X upper limit of normal (ULN) (except subjects with Gilbert Syndrome, who can have total bilirubin < 3.0 mg/dL)
AST (SGOT) and ALT (SGPT) 3.0 x ULN
Calculated creatinine clearance 45 mL/min
ECOG performance status 2 (Karnofsky 60%, see Appendix A)

Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the POMALYST REMS program
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria

Prior exposure to ixazomib OR is refractory to pomalidomide
Patients that have previously been treated with ixazomib, or participated in a study with ixazomib,whether treated with the agent or not, are also excluded
Participation in other clinical trials, including those with other investigational agents not included in this trial, within 30 days of the start of this trial and throughout the duration of this trial
Diagnosed or treated for another malignancy within 3 years prior to enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low risk prostate cancer after curative therapy
Known GI disease or is in need of, or has had a previous GI procedure that could interfere with the oral absorption or tolerance of ixazomib or pomalidomide including difficulty swallowing
Known central nervous system involvement
Systemic treatment, within 14 days before the first dose of treatment, with strong CYP3A or inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of St. John's wort OR systemic treatment within 14 days of the first dose of treatment with a strong inhibitor of CYP1A2 (ciprofloxacin, fluvoxamine, cimetidine, enoxacin, ethynyl estradiol, mexiletine)
Any medical or psychiatric illness/social situation that in the Investigator's opinion, would impose excessive risk to the patient, would adversely affect his/her participating in this study or would limit compliance with study requirements
Any active, or uncontrolled cardiovascular conditions, including but not limited to uncontrolled hypertension, uncontrolled cardiac arrhythmias, symptomatic congestive heart failure, unstable angina, grade 3 thromboembolic event or myocardial infarction within the past 6 months
The following therapies within the stated time frames prior to initiation of therapy

Those who require a limited course of radiation for management of bone pain more than 14 days out from initiation of therapy are not excluded
If the involved field is small, 7 days will be considered a sufficient interval between radiotherapy and administration of the ixazomib
Daily requirement for corticosteroids (equivalent to > 10 mg/day prednisone, though >10mg/day is acceptable if physiological levels require, so long as the dose is stable for at least 7 days prior to initiation of therapy. Inhalation corticosteroids are exempt from this criterion
