Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   44334   clinical trials with a EudraCT protocol, of which   7366   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).

    General information about the trial
    Main objective of the trial
    The primary objective of this single-arm, Phase 2 study was to evaluate the efficacy (overall response rate [ORR]) of melflufen treatment in relapsed-refractory multiple myeloma (RRMM) patients. ORR was defined as the proportion of patients for whom the best overall confirmed response to treatment with melflufen was stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR).
    Protection of trial subjects
    Prior to the initiation of any trial-specific procedures, all participating trial subject were required to sign an informed consent that had previously been reviewed and approved by an ethics committee. The safety, dose and dosing schedule of melflufen and dexamethasone in RRMM had previously been evaluated in a clinical study with patients having late-stage relapsed and relapsed refractory multiple myeloma (RRMM). The current study was designed based on well-established guidance for oncology studies including RRMM management, response assessment, and National Comprehensive Cancer Network Guidelines. Safety was monitored through the following safety assessments: documentation and follow-up of AEs and SAEs, physical examination (vital sign measurements and assessment of ECOG PS and neurological status), chest radiographs, 12-lead ECG, routine safety laboratory tests including additional reporting requirements of Grade 3 and 4 thrombocytopenia and neutropenia. Any AE that occurred after the first dose of study medication up to 30 days after the last study drug administration was recorded in the CRF and was followed for 30 days after the last study drug administration or until resolution, whichever came first. Laboratory abnormalities assessed as clinically significant were also recorded as adverse events. The Investigator recorded the grade of each clinically significant laboratory abnormality and evaluated any relationship to the study drug and clinical condition. Results were published only at a group level with no availability of individual patient data.
    Background therapy
    Patients with Relapsed Refractory Multiple Myeloma (RRMM) often have disease that is refractory to multiple drugs. In earlier treatment lines, novel agents are commonly administered in combination, resulting in disease resistant to multiple drug classes. Therefore, there is an urgent need to develop new therapies with different safety and tolerability profiles for patients with late-stage RRMM who have exhausted available therapies. Melflufen combined with dexamethasone, has the potential to fill this unmet medical need by providing a novel mechanism of action, clinically meaningful efficacy, and manageable safety in patients with RRMM.
    Evidence for comparator
    No comparator was used in the current study.

    Recruitment
    Recruitment details
    The study was conducted by 16 Investigators at 17 sites (one Investigator enrolled patients at 2 sites) and patients were enrolled in France, Italy, Spain, and the United States. The first patient initiated study treatment on December 28, 2016 and the date for last patient last visit was November 16, 2021.

    Pre-assignment
    Screening details
    Screening assessments were performed between Day -21 and Day -1. The purpose of the Screening Period was to obtain informed consent and to establish protocol eligibility. Out of the 215 screened subjects, 165 met the eligibility criteria and 157 were enrolled in the study.

    Arm description
    This was a single-arm study and all enrolled subjects/patients were treated with 28-day cycles of therapy with melflufen on Day 1 and dexamethasone on Days 1, 8, 15 and 22. Treatment was continued until documented progressive disease, unacceptable toxicity, or the patient/physician determined it was not in the patient´s best interest to continue participation in the study.

    Dexamethasone 40 mg was self-administered orally once weekly on Days 1, 8, 15 and 22 of each 28-day cycle. Melflufen was also given to the patients on Day 1 of each cycle, in addition to intake of dexamethasone. Dexamethasone 20 mg instead of 40 mg was used by subjects ≥ 75 years of age. Overall in the trial, dexamethasone was administered in the pharmaceutical form of tablets (all countries) but in some cases it was administered as injections (US only).

    The primary endpoint of this Phase 2 study was to measure the overall response rate (ORR) to treatment with melflufen in relapsed-refractory multiple myeloma (RRMM) patients. Overall response rate was defined as the proportion of patients for whom the best overall confirmed response was stringent complete response (sCR), complete response (CR), very good partial response (VGPR) or partial response (PR). All tumor response and progression-dependent endpoints were assessed by the Investigator using the International Myeloma Working Group Uniform Response Criteria (IMWG-URC).

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    31 May 2018
    The sample size was expanded to 150 patients and the two previously included patient populations were grouped into one patient population. Initially, patients were either refractory to Pomalidomide or refractory to an anti-CD38 MAb. Once it was observed that more than 70% of patients were refractory to both and the original hypothesis was void, the two groups were merged into one with the possibility to be Pomalidomide and/or anti-CD38 MAb refractory.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
