Brief Summary in Lay Language

Patients who suffer from multiple myeloma (MM) and received at least one prior MM therapy and whose disease progressed may be eligible to be treated in this study. The primary goal of the study is to assess the highest dose of Vorinostat (V) with 100mg, 200mg or 300mg), given in combination with fixed doses of Doxorubicin (D), Bortezomib (B) and Dexamethasone (D) with still acceptable side effects for the treated patient (=Maximal Tolerated Dose, MTD) (Phase I part). When the MTD is determined, additional patients may be enrolled and treated with VBDD (Phase II part).
In the final evaluation, data in regard to response rates, duration of response, progression-free and overall survival, safety of the VBDD therapy, patient´s quality of life before and after VBDD treatment, will be assessed. Furthermore, the effect of vorinostat on the plasma cells in patient´s blood and bone marrow samples will be investigated in the laboratory.

Brief Summary in Scientific Language

Prospective, open, non-randomized, non-controlled, monocenter, phase I/II clinical study with a consecutive 3 to 3 group design. Primary objective of the study is the determination of the maximum tolerated dose (MTD) of Vorinostat (V), given in combination with fixed doses of Doxorubicin (D), Bortezomib (B) and Dexamethasone (D).
Secondary objectives are:
Assessment of safety and tolerability of VBDD; efficacy data of VBDD.

Interventions/Observational Groups

  •   Vorinostat 100 mg/d, on 12 days in combination with BDD in a 28-d-cycle.
    The dose level of Vorinostat will be escalated in each new cohort if no dose limiting toxicity (DLT) occurs to 200 mg/d and 300 mg/d.
    Bortezomib will be administered intravenously (i.v.) 1.3mg/m2 on 3 days in a 28-d-cycle.
    Doxorubicin will be administered i.v. with a total dose of 18 mg/m2 per cycle.
    Dexamethasone will be administered per os (p.o.) with 40mg (first cycle) and 20mg (all other subsequent cycles) on 4 days in a 28-d-cycle.

Primary Outcome

Maximum tolerated dose (MTD) of Vorinostat, given in combination with fixed doses of Doxorubicin, Bortezomib and Dexamethasone.
The primary target variable is the occurrence of any dose-limiting toxicity (DLT) in MM patients during the first 28 days of treatment.

end of 1:1-Block primary endpoint
start of 1:1-Block secondary endpoint

Secondary Outcome

• Response rates: complete remission (CR, including stringent CR [sCR]), very good partial response (vgPR), partial remission (PR), stable disease (SD), progressive disease (PD)
• Duration of response in all 3 groups (level 0 vs. 1 vs. 2) with VBDD
• Progression-free (PFS) and overall survival (OS)
• Safety
• Specific myeloma prognostic parameters
• Quality of Life before and after VBDD treatment
