Ixazomib Citrate, Pomalidomide, Dexamethasone, and Stem Cell Transplantation in Treating Patients With Relapsed or Refractory Multiple Myeloma

• Status: Active, not recruiting
• Trial end date: 2022-07-24
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well ixazomib citrate, pomalidomide, dexamethasone, and stem cell transplantation works in treating patients with multiple myeloma that has come back or does not respond to treatment. Giving chemotherapy, such as pomalidomide and dexamethasone, before a stem cell transplant helps kill any cancer cells that are in the body and helps make room in the patient?s bone marrow for new blood-forming cells (stem cells) to grow. After treatment, stem cells are collected from the patient's blood and stored. More chemotherapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. Giving ixazomib citrate in addition to pomalidomide, dexamethasone, and stem cell transplantation may work better in treating patients with relapsed or refractory multiple myeloma.

• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject; (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

• Must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, OR

• Agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject; (Periodic abstinence [e.g., calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception)

• Willing to follow the requirements of the Pomalyst REMS program

• Willing to return to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)

Exclusion Criteria:

• Diagnosed or treated for another malignancy =< 2 years prior to registration or previously diagnosed with another malignancy and have any evidence of residual disease

• NOTE: If there is a history or prior malignancy, patient must not be receiving other specific treatment for their cancer; patients with non-melanoma skin cancer or carcinoma in situ of any type, or low-risk prostate cancer after curative therapy, are not excluded if they have undergone complete resection

• NOTE: Platelet transfusions to help patients meet eligibility criteria are not allowed =< 3 days prior to study registration

• Any of the following:

• Pregnant persons

• Nursing persons

• Persons of childbearing potential who are unwilling to employ adequate contraception

• Co-morbid systemic illnesses or other severe concurrent disease which, in the judgment of the investigator, would make the patient inappropriate for entry into this study or interfere significantly with the proper assessment of safety and toxicity of the prescribed regimens; NOTE: this includes uncompensated heart or lung disease

• Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm; NOTE: Bisphosphonates are considered to be supportive care rather than therapy and are allowed while on protocol treatment

• Patient has >= grade 2 peripheral neuropathy, or grade 1 with pain on clinical examination during the screening period

• Major surgery =<14 days prior to registration

• Systemic treatment with strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital) or use of Ginkgo biloba or St. John?s wort =< 14 days prior to registration

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. NOTE: Any electrocardiogram (ECG) abnormality at screening must be documented by the investigator as not medically relevant

• Corrected QT (QTc) > 470 milliseconds (msec) on a 12-lead ECG obtained during the screening period; Note: If a machine reading is above this value, the ECG should be reviewed by a qualified reader and confirmed on a subsequent ECG

• Failure to have fully recovered (i.e., =< grade 1 toxicity) from the reversible effects of prior chemotherapy

• Radiotherapy =< 14 days prior to registration; NOTE: If the involved field is small, 7 days will be considered a sufficient interval between treatment and administration of the ixazomib

• Central nervous system involvement with disease under study (myeloma), or concurrent AL amyloidosis or plasma cell leukemia

• Patients that have previously been treated with ixazomib, or participated in a study with ixazomib whether treated with ixazomib or not
