About this study

Official title: Comparative Study of Clinical Disorders Related to Monoclonal Gammopathy in Patients With Haematological Malignancies in Two Hospitals in Finistère Between 2012 and 2017 (GammaClinik)

Clinical symptoms associated with monoclonal gammapathy have been primarily studied in hematological malignancy and rarely in MGUS and hemopathy. Indeed, most studies focus on a specific type of clinical involvement that does not allow to understand the epidemiological distribution of clinical symptoms in this population. In addition, in most cases, studies of clinical impairment of monoclonal gammapathies focus on one symptom. This study could highlight disparities in the representation of clinical disorders associated with monoclonal gammapathies, depending on whether they are or not associated with a malignant hematology, and would provide a better overall picture of the distribution of these diseases. This study could potentially define prognosis values for certain clinical conditions that we would not find in the group of hematological malignancies. This study would also make it possible to investigate whether there are clinical disorders of monoclonal gammapathies associated with chronic lymphoma/lymphocytic leukemia. This would potentially guide future pathophysiological research. This bicentric study could, depending on the results, be supplemented later by a larger study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Search for a difference in the distribution of the various clinical conditions associated with monoclonal peaks in gammapathies of undetermined significance compared with hematological malignancies.

    The presence of a difference in the distribution of gammopathy-related clinical disorders between GMSI and hemopathies

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Gammopathy, Monoclonal, run by University Hospital, Brest at 2 sites in France.

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 35 inclusion and 1 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: finished, as of the sponsor's last update on 19 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Search for a difference in the distribution of the various clinical conditions associated with monoclonal peaks in gammapathies of undetermined significance compared with hematological malignancies. (time frame: 5 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 19 Aug 2024.
