Ixazomib With Pomalidomide, Clarithromycin and Dexamethasone in Treating Patients With Multiple Myeloma
Study Details
Study Description
Brief Summary
This phase I/II trial studies the side effects and best dose of clarithromycin when given together with ixazomib citrate, pomalidomide, and dexamethasone and to see how well it works in treating patients with multiple myeloma that has not responded to previous treatment. Biological therapies, such as clarithromycin, pomalidomide, and dexamethasone, use substances made from living organisms that may stimulate the immune system in different ways and stop cancer cells from growing. Ixazomib citrate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving clarithromycin with ixazomib citrate, pomalidomide and dexamethasone may be a better treatment for patients with multiple myeloma.

OUTLINE: This is a phase I, dose-escalation study of clarithromycin followed by a phase II study.
Patients receive pomalidomide orally (PO) once daily (QD) on days 1-21; ixazomib citrate PO on days 1, 8, and 15; clarithromycin PO twice daily (BID) on days 15-21 of course 1 and days 1-21 and courses 2-6; and dexamethasone PO on days 1, 8, 15, and 22. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.
MAINTENANCE THERAPY:
Patients receive pomalidomide, ixazomib citrate, and dexamethasone as above and receive clarithromycin PO BID or QD. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 2-3 months for up to 3 years.

Outcome Measures
Primary Outcome Measures
- MTD of clarithromycin when given in combination with ixazomib citrate, pomalidomide, and dexamethasone assessed by the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (Phase I) [28 days]
The MTD is defined as the highest dose tested in which fewer than 33% of patients experience a dose limiting toxicity and at least 6 patients have been treated at that dose. The MTD will be the recommended Phase 2 dose, provided that other safety considerations are acceptable.
Secondary Outcome Measures
- Clinical best response [Up to 3 years]
Will be listed for each patient and summarized using standard descriptive methods.
Other Outcome Measures
- Change in immune modulation with the addition of clarithromycin (Phase II) [Up to 3 years]
Regression methods (adapted for repeated measures) will be used to describe the changes over time; these regression models will contain contrasts to compare changes from baseline to day 15, and from day 1 of subsequent cycles. P-values calculated based on the regression analyses will be used to calibrate the strength of associations and patterns observed, rather than for drawing definitive conclusions. Additional analysis will be undertaken to explore the relationship between changes (or lack of changes) and response.
- Change in immune modulation without the addition of clarithromycin (Phase II) [Baseline to up to 3 years]
Regression methods (adapted for repeated measures) will be used to describe the changes over time; these regression models will contain contrasts to compare changes from baseline to day 15, and from day 1 of subsequent cycles. P-values calculated based on the regression analyses will be used to calibrate the strength of associations and patterns observed, rather than for drawing definitive conclusions. Additional analysis will be undertaken to explore the relationship between changes (or lack of changes) and response.
- Pharmacokinetic parameters of ixazomib citrate (Individual and mean plasma ixazomib concentration data) [At 0.5, 1, 1.5, 2, 4, 8, and 24 hours after ixazomib citrate administration on days 1 and 8]
Individual and mean plasma ixazomib concentration data will be plotted over time. A summary table will be presented for the plasma concentration data.
