A Phase 2 interventional study of Ixazomib Citrate and Laboratory Biomarker Analysis in Plasma Cell Myeloma and Transplant-Related Carcinoma, sponsored by Fred Hutchinson Cancer Center. Completed at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-25.
Sponsored by Fred Hutchinson Cancer Center · Phase 2, Interventional, and Treatment
This phase II trial studies the safety of alternating ixazomib citrate and lenalidomide as treatment to help keep cancer from coming back after stem cell transplant (maintenance therapy) in treating patients with multiple myeloma. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Lenalidomide may stimulate the immune system to attack cancer cells. Giving ixazomib citrate and lenalidomide as maintenance therapy after transplant may prolong the length of time until the cancer returns.
PRIMARY OBJECTIVES:
I. Evaluate the toxicity of the use of ixazomib (ixazomib citrate) and lenalidomide as maintenance therapy after autologous transplant.
SECONDARY OBJECTIVES:
I. Evaluate the ability to deliver the planned therapy.
II. Assess initial response to therapy.
III. Evaluate the median time to disease progression.
IV. Assess overall survival.
OUTLINE:
Within 30-120 days after completion of autologous transplant, patients receive ixazomib citrate orally (PO) on days 1, 8 and 15 every 28 days for 2 courses, followed by lenalidomide PO once daily (QD) on days 1-28 for 2 courses. Treatment repeats, alternating after every 2 courses, for up to 24 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 3 months for 2 years.
3,632 studies on the registry are indexed under Multiple Myeloma; 745 are open to participants now.

Exclusion Criteria:
Within 30-120 days after finishing autologous transplant, patients receive ixazomib citrate PO on days 1, 8 and 15. Treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients then receive lenalidomide PO QD on days 1-28. Treatment repeats for up to 2 courses in the absence of disease progression or unacceptable toxicity. Patients will continue to alternate between ixazomib citrate and lenalidomide every 2 courses for up to 24 months in the absence of disease progression or unacceptable toxicity.
