Bortezomib is an established treatment in multiple myeloma; it is common practice in the UK to administer bortezomib with dexamethasone. This practice is based on data that supports improved response rates with this combination.
Recent trial data indicates that the addition of vorinostat to bortezomib treatment overcomes treatment resistance to bortezomib. As such this current trial is designed to investigate the efficacy, safety and tolerability of combination treatment with vorinostat, bortezomib and dexamethasone in patients with relapsed and relapsed refractory myeloma.
A comparison of this Phase II trial with the pivotal Phase III trial conducted by MSD (using the labelled bortezomib indication without dexamethasone) will address the impact of dexamethasone in regards to tolerability and additional efficacy in myeloma patients.

|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|
|Official Title:||A Phase II Trial of Combination Treatment With Vorinostat, Bortezomib and Dexamethasone in Patients With Relapsed and Relapsed Refractory Multiple Myeloma|
|Study Start Date :||August 2013|
|Primary Completion Date :||August 2015|
|Estimated Study Completion Date :||August 2017|
Experimental: Vorinostat Velcade Dexamethasone (VVD)
Up to 8 cycles of VVD followed by vorinostat maintenance until disease progression.
Cycles 1-8 (21-day cycle)
Drug: Vorinostat Velcade Dexamethasone
Other Name: Bortezomib (velcade)
- Overall response rate to vorinostat, bortezomib and dexamethasone. [ Time Frame: up to 24 weeks ]To assess the number and proportion of participants with at least a partial response (PR) or better within 8 cycles of protocol treatment with vorinostat, bortezomib and dexamethasone.
- Number of dose reductions during treatment with vorinostat, bortezomib and dexamethasone. [ Time Frame: up to 24 weeks ]To assess the dose reduction profile of combination treatment with vorinostat, bortezomib and dexamethasone. The proportion of participants experiencing a dose reduction or terminating treatment early due to toxicity will be assessed.
- Overall numbers and rates of adverse events [ Time Frame: Up to 18 months ]Safety and toxicity analyses will summarise the overall serious adverse event and adverse events rates including the number and proportion of participants with at least one safety event. SAEs will be additionally presented by the relationship to study treatment, seriousness criteria, event outcome, duration and by MedDRA body system coding.
- Progression free survival [ Time Frame: Up to 18 months ]A progression-free survival curve will be calculated using the Kaplan Meier method and median PFS estimates will be presented
- Maximum response to treatment [ Time Frame: Up to 24 weeks ]The overall number and proportion of participants in each response category within 8 cycles of treatment and overall across all treatment including the maintenance phase
- Time to maximum response [ Time Frame: Up to 18 months ]The time to maximum response will be calculated from the date of registration to the date of maximum response. Participant's who progress and do not achieve a maximum response will be censored at the time of progression. Median time to maximum response will be presented.
- Matched pairs analysis [ Time Frame: Up to 24 months ]A matched pairs analysis will be carried out looking at overall response, PFS, dose reductions and toxicity in participants treated with vorinostat in combination with bortezomib and dexamethasone (VVD) in this current study compared to participants randomised to the bortezomib/vorinostat (VV) arm in the pivotal MSD phase III study.
