Summary
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.

Exclusion Criteria:

- Previous anti-tumour therapies, including prior experimental agents or approved anti-tumour small molecules and biologics, within 28 days before the start of protocol treatment. Steroid therapy to stop rapid relapse during this period is permitted, but must be stopped 7 days prior to study drug administration.

- Participants who have received growth factor support or platelet support within 14 days prior to registration

- Participants with uncontrolled concurrent illness or circumstances that could limit compliance with the study.

- Patients with significant cardiovascular or pulmonary disease

- Active symptomatic fungal, bacterial, and/or viral infection including known active HIV or known viral (A, B, or C) hepatitis.

- Pregnant or breast feeding females

- Unable to take corticosteroid therapy at study entry

- Participants with known hypersensitivity to any components of bortezomib, (such as boron, mannitol), vorinostat or dexamethasone.

- Participant has known CNS metastases and/or carcinomatous meningitis.

- Participants with a history of a gastrointestinal surgery or other procedures that might, in the opinion of the Investigator, interfere with the absorption or swallowing of the study drug(s)
