General information about the trial
|
|||
Main objective of the trial |
To determine the efficacy of a prolonged treatment with bortezomib twice monthly s.c. in association with dexamethasone, after a salvage treatment containing bortezomib i.v. in relapsed and refractory multiple myeloma patients.
- To assess the safety of prolonged treatment with bortezomib s.c.

||
Protection of trial subjects |
The study will be conducted in accordance with ethical principles founded in the Declaration of Helsinki. The IRB/IEC will review all appropriate study documentation in order to safeguard the rights, safety and well-being of the patients. The study will only be conducted at sites where IRB/IEC approval has been obtained. The protocol, Investigator’s Brochure, informed consent, advertisements (if applicable), written information given to the patients (including diary cards), safety updates, annual progress reports, and any revisions to these documents will be provided to the IRB/IEC by the investigator

Substantial protocol amendments (globally) |
|||
Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
24 Jun 2013 |
Substantial Amendment n.1:
With this amendment a third maintenance arm was added, with subcutaneous Velcade and dexamethasone upon the occurrence of biochemical relapse (Arm C).
It should be noted that a comparison will be made between the control arm Arm B (no maintenance) and the two experimental arms Arm A (prolonged VD) and Arm C to demonstrate the superiority of the experimental arms. This means that the control arm will be the same for both experimental arms, and the two experimental arms will not be compared to each other.
This change led to an increase in the sample, therefore 216 patients will have to be enrolled.
|
||
18 Mar 2014 |
Substantial Amendment n.2:
With this amendment, a change was made to the study design. More precisely, patients randomized to Arm C, upon the occurrence of biochemical relapse, will be treated with 6 cycles of treatment (Velcade and Dexamethasone).
Velcade and Dexamethasone will be administered on days 1, 8, 15, 22.
This treatment will be repeated at each biochemical relapse until the clinical relapse of the disease. |
||
10 Nov 2015 |
Substantial Amendment n.3:
Considering the experimental nature of the maintenance treatment, it was deemed appropriate to reduce the sample of patients to be subjected to the treatment in order to obtain a preliminary evaluation on a small number of patients. Furthermore, this preventive measure will allow us not to expose an excessive number of patients to a treatment that may be too toxic or ineffective.
With this amendment, one of the primary objectives is to evaluate the efficacy and feasibility of maintenance treatment with bortezomib administered in combination with dexamethasone at biochemical relapse, after salvage treatment containing bortezomib. Therefore a comparison will be made between Arm B and Arm C.
With this sample reduction, 46 patients will need to be enrolled (23 per arm). |
||
04 Apr 2017 |
Substantial Amendment n.4:
This amendment was necessary to update the contacts of the Sponsor and the Principal Investigator from the study, as well as update the criteria for evaluating the disease response.
This amendment also transmits the instructions relating to monitoring the temperature of the drug bortezomib, provided by the company supplying the drug B&C, under the instructions of Janssen International.
The participating centers will have to communicate any temperature excursion, verified during transport until delivery to each individual center.
The side effects of the drug Velcade were also updated on the informed consent and those of Dexamethasone were added. |
||
20 Apr 2021 |
Substantial Amendment n.5:
The request for a substantial amendment concerns the change of the promoter of the study from HOVON Foundation to STICHTING EUROPEAN MYELOMA NETWORK (EMN) and the updating of the side effects of the drug bortezomib, reported on the information sheet and informed consent form.
Following this change of promoter, all study documents have been modified. |
