A Phase II Study of Belinostat in Combination With Bortezomib in Patients With Relapsed, Refractory Multiple Myeloma

• Status: Terminated
• Trial end date: 2007-06-01
• Target enrollment: 0
• Participant gender: All

Summary

This open-label study will assess anti-tumor activity and safety of belinostat in combination with bortezomib (Velcade®) in multiple myeloma patients refractory to or relapsed from at least one prior bortezomib-containing regimen. Subjects will be administered both PXD101 and bortezomib on the same days: i.e. days 1, 4, 8, and 11 of a 3-week cycle, for up to 8 cycles.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Onxeo
• Treatments: Belinostat; Bortezomib

Criteria

Inclusion Criteria:

• Diagnosis of multiple myeloma.

• Status of refractory to or relapsed from at least one prior bortezomib-containing regimen.

• Progressive disease.

• Age >= 18 years.

• Karnofsky performance status >= 60%

• Acceptable liver function:

• Bilirubin =< 1.5 x ULN (upper limit of normal)

• Estimated life expectancy greater than 3 months.

• Signed, written IRB (institutional Review Board)-approved informed consent.

Exclusion Criteria:

• Non-secretory multiple myeloma or symptomatic amyloidosis.

• Hypersensitivity to bortezomib, boron, or mannitol.

• Less than 4 weeks since prior chemotherapy, radiotherapy, endocrine therapy, or immunotherapy, except if disease is rapidly progressing.

• Less than 4 weeks since prior use of other investigational agents.

• Serious concomitant systemic disorders (e.g. active infection).

• Significant cardiovascular disease.

• Marked baseline prolongation of QT/QTc (corrected QT interval)interval.

• Non-willingness to use effective contraceptive methods for patients of child-bearing age / potential.

• Pregnant or breast-feeding women.

• Known HIV positivity.

• Prior treatment with belinostat (PXD101), or any other HDAC (histone deacetylase) inhibitor.

• Altered mental status which precludes an understanding of the Informed Consent Document.
