About this study

Official title: Local, Multicentre, Non-Interventional Study of Early Diagnostics of Multiple Myeloma Relapses Evaluation in Real Life Practice in the Russian Federation

The main aim of this study is to learn how long it takes for people with MM to have a relapse after their first treatment. Not all participants will have a relapse during the study.

Participants will visit their clinic every 3 months and be treated according to their clinic's standard practice.

The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.

Read the detailed description

This is a non-interventional, prospective study of participants with MM relapses. This study will assess the low detection rate of biochemical relapses which will improve routine clinical practices and management of participants with MM in real world practice.

The study will enroll approximately 350 participants. The data will be collected both prospectively and/or retrospectively at the specialized care (hematology) and will be recorded into electronic case report forms (e-CRFs) of the electronic data capture (EDC) system. All the participants will be assigned to a single observational cohort:

  • Participants With MM

This multi-center study will be conducted in the Russian Federation. The overall duration of the study will be approximately 4 years. The overall time for treatment and follow-up period will be approximately 2.5 years for each participant.

Study groupRoleWhat they receive
Participants With MMParticipants diagnosed with MM (complete response [CR], very good partial response [VGPR] and partial response [PR]) and who have received one prior first line treatment within 3 months preceding the enrollment, will be observed retrospectively and medical data will be monitored and collected prospectively every 3 months until the second biochemical and symptomatic relapse is identified.

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple Myeloma, run by Takeda at 24 sites in Russia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 22 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Russia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Median Time From the Start of First Line Therapy of Participants With MM to First Biochemical Relapse of MM (time frame: From the start of the first line therapy until first biochemical relapse (up to approximately 4 years)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2026.
