This is an open-label, single arm, multi-center study of oral panobinostat administered in combination with bortezomib and dexamethasone in patients with relapsed, and relapsed and refractory multiple myeloma. - Panobinostat will be administered in combination with bortezomib and dexamethasone over 2 weeks in each 21 day cycle; the third week will be without administration of any drug. - Treatment phase 1 will consist of 8, 21 day cycles (24 weeks). Patients with clinical benefit at the end of cycle 8 as per investigator assessment may continue to receive study treatment in phase 2 for a maximum of an additional 24 weeks. - Patients who have not achieved or maintained at least "no change" (EBMT response criterion) by 8 cycles must discontinue from study treatment - The protocol will remain open in each participating country until drug is commercially available and reimbursable or until July 2017, whichever comes first (except in Norway where this protocol will end by March 2016). Dosing schedule for treatment is detailed below: Treatment Phase 1 (weeks 1-24 starting C1D1) - PAN given three times per week (TIW), weeks 1 & 2 of each 3-week cycle (Cycle days 1,3,5,8,10, and 12) - BTZ given twice a week (BIW) weeks 1 & 2 of each 3-week cycle (Cycle days 1,4,8, and 11) - Dex given for 2 days twice a week (BIW), with BTZ on weeks 1 & 2 of each 3-week cycle (Cycle days 1,2,4,5,8,9,11, and 12) Treatment Phase 2 (24 weeks starting C9D1) - PAN given TIW, weeks 1 & 2 of each 3-week cycle (Cycle days 1,3,5,8,10, and 12) - BTZ given once a week, weeks 1 & 2 of each 3 week cycle (Cycle days 1 and 8) - Dex for 2 days once a week with BTZ, weeks 1 & 2 of each 3-week cycle (Cycle days 1,2,8, and 9)
Panobinostat (PAN [LBH589]) is an orally administered pan-deacetylase inhibitor (DACi) belonging to a structurally novel class of compounds deregulating cell proliferation and survival mechanisms of cancer cells.

Placement of an intrauterine device (IUD) or intrauterine system (IUS) 3. Barrier methods of contraception: Condom or Occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
Women are considered post-menopausal and not of child bearing potential if they have had 12
months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age
appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy
(with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of
oophorectomy alone, only when the reproductive status of the woman has been confirmed by
follow up hormone level assessment is she considered not of child bearing potential.
