Vorinostat and Bortezomib in Treating Patients With Relapsed or Refractory Multiple Myeloma
Study Details
Study Description
Brief Summary
This phase I trial is studying the side effects and best dose of vorinostat when given together with bortezomib in treating patients with relapsed or refractory multiple myeloma. Vorinostat and bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving vorinostat together with bortezomib may kill more cancer cells

Detailed Description
PRIMARY OBJECTIVES:
-
Determine the maximum tolerated dose (MTD) of vorinostat (SAHA) when given together with bortezomib in patients with relapsed or refractory multiple myeloma (MM).
-
Determine the toxicity of this regimen in these patients.
SECONDARY OBJECTIVES:
-
Determine whether giving SAHA together with bortezomib inhibits histone deacetylation in normal cells (buccal mucosal cells and/or peripheral blood monocytes) as well as in MM cells.
-
Evaluate the effect of dexamethasone when given together with SAHA and bortezomib.
-
Explore molecular mechanisms involved in apoptosis in MM mediated by SAHA and bortezomib.
-
Correlate change of histone acetylation with clinical outcome in patients treated with this regimen.
OUTLINE: This is a multicenter, dose escalation study of vorinostat (SAHA).
Patients receive bortezomib IV on days 1, 4, 8, and 11 followed by oral SAHA twice daily on days 4-11. Beginning in course 3, some patients may receive low-dose oral dexamethasone on days 4-8. Treatment repeats every 21 days for up to 8 courses in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients receive escalating doses of SAHA until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. An additional cohort of 10 patients receive treatment at the MTD.
Patients undergo blood collection and tumor biopsies periodically during study for pharmacologic and biomarker correlative studies.
After completion of study treatment, patients are followed at least once a month.

Outcome Measures
Primary Outcome Measures
- Maximum tolerated dose (MTD) of SAHA in combination with bortezomib determined by dose-limiting toxicities [21 days]
Secondary Outcome Measures
- Inhibition of histone deacetylation [Up to 1 month]
- Response [Up to 1 month]
The estimates and the corresponding 90% confidence intervals will be calculated.
- Survival (disease specific and overall) [Up to 1 month]
Will be estimated using the Kaplan-Meir method.
