Why
  1. Recurrence describes something many studies share rather than a condition a study is about.
  2. The study's listed conditions name Multiple Myeloma.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The importance of real-world evidence studies stems from the following considerations. The study population of a specific clinical trial needs to meet strict inclusion and exclusion criteria, which result in a population of participants that is not necessarily representative of the study population of interest treated in routine care. Furthermore, the outcomes of a clinical trial occur under controlled conditions that do not necessarily reflect the routine healthcare practice. This is especially true among patient populations with challenging to treat disease such as in MM, where personalized therapeutic approaches are commonly considered taking into consideration the patients' age and associated comorbidities, among other factors. In addition, observational studies, due to their non-interventional nature, often show increased degree of heterogeneity across the enrolled patient populations compared to clinical studies, thus aiding generalizability of the results.

In light of the above and due to the scarcity of evidence regarding the outcomes for patients with RRMM receiving Pom/LoDex in routine clinical practice, this retrospective chart review and prospective observational study aims to assess the PFS and response to treatment as well as to obtain real-world evidence on the utilization patterns and management strategy of Pom/LoDex in routine clinical care settings in Greece.

This is a non-interventional, multicenter, single-country, retrospective chart review and prospective cohort study which will include a representative sample of patients with RRMM who have been initiated on Pom/LoDex between 01 January 2016 and 28 February 2019 in the third line and beyond treatment setting under routine care conditions in Greece.

The study will be carried out by hospital-based hematology specialists practicing in geographically diverse locations throughout Greece and will be conducted under real-world conditions of daily clinical practice.

Study population

A total of 100 adult patients with RRMM who have been initiated on Pom/LoDex treatment as indicated in the product's Summary of Product Characteristics (SmPC) (i.e., after having received at least two prior therapies including both lenalidomide and bortezomib and whose disease progressed after the last treatment) between 01 January 2016 and 28 February 2019 and who are eligible for participation in the study according to the inclusion and exclusion criteria -as outlined in Section 10- are planned to be recruited in the present clinical study. For the justification of the sample size please refer to Section 13.1.

Eligibility criteria

  • Patients eligible for inclusion in this study have to meet all of the following criteria:

    • Adult subjects (aged ≥18 years) of either gender.
    • Subjects with a documented RRMM diagnosis according to IMWG or EBMT criteria prior to Pom/LoDex treatment.
    • Subjects who have been initiated on Pom/LoDex treatment as per the product's Summary of Product Characteristics (SmPC) between 01 January 2016 and 28 February 2019, after having received at least two prior therapies including both lenalidomide and bortezomib and whose disease progressed after the last treatment.*
    • Note: Retrospective patients who at the time of their enrollment in the study have already completed 3 or more cycles with Pom/LoDex must have available at least one post-baseline response assessment
    • Subjects with available medical files/records and detailed historical data on their disease course and clinical management.
    • Provision of signed form (ICF) for collecting and analyzing medical data pertinent to the objectives of this study.**

      • Note: For retrospective subjects who are deceased at the date of enrollment into the study a waiver of consent will be requested by the Hospital Scientific Committee and/or Administrative Board of each participating site to either implement a hospital ICF already in place or provide written approval of this study- specific waiver. In the occasion that waiver of consent is not granted by the Scientific Committee and/or Administrative Board of the study site, deceased subjects will not be enrolled in the study.

Exclusion Criteria:

A patient who meets any of the following criteria will be excluded from participation in this study:

  • Prior (within the 3 years preceding initial diagnosis of MM).
  • Concurrent administration of anti-cancer regimens for malignancies other than MM.
  • Subjects currently participating or who have participated, during the treatment phase, in any program with interventions outside of routine clinical practice.
Terms in these criteria, in plain language(3)

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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Feb 2020, 27 months.

Of 66 industry-sponsored observational studies under Multiple Myeloma, half reached primary completion within 49 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 70. This study's 27 months is below that.

Counting every sponsor, half of 239 studies reached it within 61 months; a quarter within 30 and three quarters within 126.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 12, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
