- Conditions
- Multiple Myeloma in Relapse
- Interventions
- Registration Number
- NCT01394354
- Lead Sponsor
- University Hospital Freiburg
- Brief Summary
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.
- Detailed Description
A first cohort of three patients will be treated at the starting dose level of Vorinostat 100 mg/d, on day 1-4, 8-11, and 15-18 in combination with BDD.
The dose level of Vorinostat will be escalated in each new cohort:
if no dose limiting toxicity (DLT) has been observed in the previous dose level in 3 patient, the second cohort of 3 new patients will be treated with Vorinostat 200 mg/d and the third cohort will be given Vorinostat with 300 mg/d.
Bortezomib will be administered intravenously (i.v.) 1.3mg/m2 d1, 8, 15. Doxorubicin will be administered i.v. with a total dose of 18 mg/m2 per cycle (9 mg/m2, d1 and 8).
Dexamethasone will be administered per os (p.o.) with 40mg (first cycle) and 20mg (all other subsequent cycles) on d1, 8, 15, 22.

Group Intervention Description 1 Vorinostat Vorinostat. To determine the MTD, dose escalation for Vorinostat will be conducted following the "3 + 3 design The first cohort of 3 patients will be given 100mg/d on days 1-4, 8-11, 15-18. The second cohort of 3 new patients will be treated with Vorinostat 200mg/d. The third cohort will be given Vorinostat 300mg/d. Cycles will be repeated every 28 days. Maximum treatment cycles: 6. Bortezomib will be administered intravenously (i.v.) 1.3mg/m2 BSA an days 1, 8, 15. Doxorubicin will be administered i.v. with a total dose of 18mg/m2 BSA per cycle (9mg/m2 BSA, d1 and 8). Dexamethasone will be administered per os (p.o.) with 40mg (first cycle) or 20mg (all other cycles) on d1, 8, 15, and 22. 1 Bortezomib Vorinostat.

- Primary Outcome Measures
Name Time Method Maximal Tolerated Dose (MTD) 28 days (within first treatment cycle) The Maximal Tolerated Dose (MTD) is estimated as the highest dose at which less than two DLTs in 6 patients are observed in the first cycle. MTD estimation is based on the phase I part of the trial. However, the number of DLT's in the first cycle of the phase II patients will be inspected and discussed as well. The primary target variable is the occurrence of any dose-limiting toxicity (DLT) in MM patients during the first 28 days of treatment.
- Secondary Outcome Measures
Name Time Method Duration of Response up to one year after inclusion of the last patient Clinical assessment
Response up to 1 year after inclusion of the last patient complete remission (CR, including stringent CR \[sCR\]), very good partial response (vgPR), partial remission (PR), stable disease (SD), progressive disease (PD). These parameters will be evaluated according to IMWG criteria.
Quality of Life during screening period (within 28 days) before start of treatment and at EOT (whether after the completion of the anticipated 6 cycles of chemotherapy or at an earlier time point if patient has to stop treatment because of clinical reasons) Assessment with Quality of Life-Questionnaire SF-12
Overall survival (OS) up to 1 year after inclusion of the last patient estimation by using Kaplan-Meier method
Rates of Adverse Events (AE),Serious Adverse Events and AEs leading to permanent treatment discontinuation 9 months throughout time of treatment (6 months) + 3 months after end of treatment (Follow-up).
Rates of AE, Serious AE and AEs leading to permanent treatment discontinuation will be provided with accompanying 2-sided 95% confidence intervals. Safety parameters will be analyzed descriptively.
An AE is any untoward medical occurrence in a patient administered any dose of VBDD study drugs and is defined in detail in the clinical trial protocol. An AE can be any unfavorable sign (incl. an abnormal lab and ECG-findings etc.), symptom, or disease related or not to the study drug.Progression-free survival (PFS) up to 1 year after inclusion of the last patient estimation by using Kaplan-Meier method
