Study summary

Multiple myeloma is the second most common hematologic malignancy in adults and despite the new therapies that have been developed in the last decades it remains incurable. Over the course of the disease, patients eventually become refractory to the various treatments. Therefore, new therapeutic options which utilize new mechanisms of action are essential.

Melphalan flufenamide (melflufen) represents such an additional therapeutic approach. Melflufen is a peptide-drug conjugate (PDC) which is highly lipophilic and rapidly incorporated into the tumor cells. Once inside the tumor cell, melflufen is hydrolyzed by peptidases, including aminopeptidases and esterases, to release its alkylator payload. The alkylating agent then induces DNA damage resulting in cell death.

Melphalan flufenamid in combination with Dexamethason was approved by the European Medicines Agency (EMA) in August 2022 for the treatment of patients with triple class refractory relapsed/refractory Multiple Myeloma who have received at least 3 prior lines of therapy. For patients with prior autologous stem cell transplantation, the time to progression should be at least 3 years from transplantation.

The non-interventional study MARINA aims to address open scientific questions regarding the effectiveness, as well as therapy and safety management of melflufen in a real-world setting. By collecting comprehensive real-world data - including the Disease Control Rate (DCR) as a key endpoint, which is of most value for patients in this late disease stage - MARINA will investigate the therapeutic benefit of melflufen in routine clinical practice.

Study population

Adult patients (≥18 years old) with relapsed and/or refractory multiple myeloma (R/RMM) pretreated with a proteasome inhibitor, an immunomodulatory drug and a CD38 antibody with decision for treatment with melflufen (Pepaxti®) and dexamethasone in fourth or later line according to SmPC.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with R/RMM who have previously been treated with at least one proteasome inhibitor, one immunomodulatory agent, and one anti-CD38 monoclonal antibody, and who on or after the last therapy
  • Indication and decision for fourth- or treatment with melflufen (Pepaxti®) and dexamethasone, according to current SmPC as assessed by the treating physician
  • Signed and dated written *.
  • Treatment decision before inclusion into this non-interventional study
  • Age ≥18 years

    • Patients are allowed to be enrolled up to 28 days (+ 14 days) after their first dose of melflufen+dexamethasone,, but before any response assessment and second dose of melflufen+dexamethasone. These patients will not participate in the PRO assessments.

Exclusion criteria

Exclusion Criteria:

  • Participation in an interventional clinical trial (except follow-up)
  • Patient unable to consent
  • according to current SmPC
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Disease control rate (DCR)

    DCR is defined as the proportion of patients achieving a remission (i.e., sCR, CR, VGPR or PR or MR) or stable disease as best response according to local medical standards during treatment with melflufen. Patients without response measurement are considered non-responders.

    Time frame: max. 38 months (FPI - LPLV)

Secondary outcomes

  1. Progression-free survival (PFS)

    PFS is defined as the time from start of melflufen treatment until first progression or death from any cause, whichever comes first. Patients without disease progression or death at the time of analysis will be censored at their date of last contact. PFS will be calculated using the Kaplan-Meier method.

    Time frame: max. 38 months (FPI - LPLV)

  2. Overall survival (OS)

    OS is defined as the time from start of melflufen treatment until death from any cause. Patients without documented death will be censored with their date of last contact. OS will be calculated using the Kaplan-Meier method.

    Time frame: max. 38 months (FPI - LPLV)

  3. Overall response rate (ORR)

    ORR is defined as the proportion of patients achieving a remission (sCR, CR, VGPR or PR or MR) as best response according to local medical standards. Patients without response measurement are considered non-responders.

    Time frame: max. 38 months (FPI - LPLV)

  4. Duration of treatment with melflufen

    Duration of melflufen treatment will be calculated in weeks as the time from first application to the last documented application of melflufen.

    Time frame: max. 38 months (FPI - LPLV)

  5. Clinical benefit rate (CBR)

    CBR is defined as the proportion of patients achieving a sCR, CR, VGPR, PR or MR as best response according to local medical standards during treatment with melflufen. Patients without response measurement are considered non-responders.

    Time frame: max. 38 months (FPI - LPLV)

  6. Time to next treatment (TTNT)

    TTNT is defined as the time from start of melflufen treatment until start of the following therapy line or death, whichever comes first. Patients alive and without subsequent treatment at the time of analysis will be censored at their date of last contact. TTNT will be calculated using the Kaplan-Meier method.

    Time frame: max. 38 months (FPI - LPLV)

  7. PFS2

    PFS2 is defined as the time from start of melflufen treatment until progression or death during first subsequent treatment line, whichever comes first. If subsequent line is not reached, previous-line death will serve as event. Patients without progression after the start of the subsequent line or death at the time of analysis will be censored at their date of last contact. PFS2 will be calculated using the Kaplan-Meier method.

    Time frame: max. 38 months (FPI - LPLV)

  8. PFS of first subsequent treatment line

    PFS of first subsequent treatment line is defined as time from start of first subsequent treatment line until first progression thereafter, or death from any cause, whatever comes first. Patients without progression or death at the time of analysis will be censored with their date of last contact. PFS of first subsequent treatment line will be calculated using the Kaplan-Meier method.

    Time frame: max. 38 months (FPI - LPLV)

  9. (Serious) adverse events ((S)AE)
