Mastocytosis, Indolent SystemicDALY-MASTNCT05923372
Evaluation of the DALY on a Cohort of Patients With Indolent Systemic Mastocytosis
An observational study of Mastocytosis, Indolent Systemic, run by University Hospital, Toulouse at 1 site in France.
Trial summary
Mastocytosis is a group of pathologies characterized by the accumulation and/or clonal proliferation of abnormal mast cells in various organs. The impact of mastocytosis on health, quality of life, the psychoaffective sphere and on professional life constitutes the burden of this disease. Read more about this study

About this study
Official title: Evaluation of the Disability-Adjusted Life Year (DALY) on a Cohort of Patients With Indolent Systemic Mastocytosis (ISM)
Mastocytosis is a group of pathologies characterized by the accumulation and/or clonal proliferation of abnormal mast cells in various organs. The impact of mastocytosis on health, quality of life, the psychoaffective sphere and on professional life constitutes the burden of this disease. The DALY is the disability-adjusted life expectancy, which takes into account the life expectancy and the number of years "lost" due to illness, disability or early death. Due to the major impact of the disease this study evaluates the DALY in indolent mastocytosis patients
Read the detailed description
Mastocytosis is a group of pathologies characterized by the accumulation and/or clonal proliferation of abnormal mast cells in various organs. Mastocytosis is a rare disease with an estimated prevalence of between 1/20,000 and 1/40,000. The impact of mastocytosis on health, quality of life, the psychoaffective sphere and on professional life constitutes the burden of this disease. This is probably important but very little studied so far. The DALY is the disability-adjusted life expectancy. It is calculated by subtracting from life expectancy the number of years "lost" due to illness, disability or early death.
Ignorance of the disease and diagnostic error cause significant distress in patients. In our clinical experience, the impact of the disease on the personal, social, and professional life of our patients is major. It therefore seems important to better specify the impact on the quality of life and the costs of this pathology. The main objective of this study is to evaluate the DALY in indolent mastocytosis patients from the CEREMAST reference center of the Toulouse University Hospital.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Patients with indolent systemic mastocytosis (IMS) | Patients with IMS, included in the CEREMAST registry and who have given their consent to participate |
What is being measured
The primary outcome is the main question the study is designed to answer.
DALY
DALY (Disability Adjusted Life Year): Its calculation consists of subtracting from life expectancy the number of years "lost" due to illness, disability or early death.
Measured: Day 1
Secondary outcomes (2)
Quality of life based on the MC QOL scale
The quality of life of the included patients will be described with the The Mastocytosis Quality of Life Questionnaire (MC-QoL) which has scores from 0 to 100, where higher scores indicate higher health-related quality-of-life impairment
Measured: Day 1
Frequency of symptoms
The frequency of various symptoms of mast cell activation will also be described.
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Mastocytosis, Indolent Systemic, run by University Hospital, Toulouse at 1 site 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 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: status not confirmed, as of the sponsor's last update on 12 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Cristina BULAI LIVIDEANU, MD (0567778138, livideanu.c@chu-toulouse.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
DALY (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05923372, which also lists 11 linked publications.
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 12 Jul 2023.
