2.Male or female patients with age =18 years without upper age limit
3.Patients with refractory or relapsed MM after at least first-line chemotherapy (CTx) or PBSCT (autologous and allogeneic SCT). All lines of relapse are eligible.
4.Measurable disease, defined as any quantifiable serum M-protein value OR in light-chain-MM elevated measurable serum free light chains OR in non-secretory MM measurable disease in terms of extramedullary sites and/or Bone marrow (BM) plasmocytosis >10%, 24-h-urine M-protein
5.Non-secretory disease allowed, provided magnetic resonance imaging (MRI) or positron emission tomography (PET) or computed tomography (CT) scan can accurately measure at least one plasmocytoma lesion and/or BM-plasmocytosis allows to determine response
6.Patient must be at least 30 days from prior CTx, radiation therapy, biological therapy, immunotherapy, major surgery or any other investigational anticancer therapy prior to the first dose of study drugs.
7.KPS =60%
8.Normal serum potassium and magnesium
9.Adequate BM function (ANC =1000/mm3, platelet count =50.000/mm3, Hb >7 g/dl, unless myelosuppression is secondary to BM plasmocytosis >70% involvement)
10.Adequate hepatic and renal function (AST and ALT =2.5 times ULN, Bilirubin =1.5 times ULN, eGFR >20 ml/min)
11.Patient is able to swallow pills/oral medication

Exclusion Criteria

1.Patient has had prior treatment with Vorinostat or HDAC inhibitors
2.Patient has previously been unable to tolerate prior treatment with Bortezomib, Doxorubicin (or other anthracyclines) or Dexamethasone, or has a known hypersensitivity to any components of Bortezomib, Doxorubicin, Vorinostat or Dexamethasone
3.Previous treatment above maximum cumulative doses of doxorubicin (> 550mg/m2), daunorubicin (> 550mg/m2), epirubicin (> 900mg/m2), idarubicin (> 120mg/m2), and/or other anthracyclines.

5.Patients with other active severe illness, including patient is known to be Human Immunodeficiency Virus (HIV) positive or has clinically active Hepatitis B or C.
6.Patient has preexisting NCI CTC =grade 3 neuropathy.
7.Patient with known CNS MM-involvement and/or MM-related/induced meningitis
8.Concomitant use of any other investigational drug or participation in a clinical trial within the last thirty days before the start of this study, previous participation in this study
9.Known or persistent abuse of medication, drugs or alcohol
10.In case of a patient without legal capacity who is unable to understand the nature, significance and consequences of the study, a legal representative has to give and sign the patient informed consent form.
11.Persons who are in a relationship of dependence/employment with the sponsor or the investigator
12.Female patients with current or planned pregnancy or during nursing period
