Study summary

This study will involve 27 centers in Italy. Since this is a multidisciplinary disease, participating centers may be from various medical areas (hematology, dermatology, allergy, etc.).

The study will last 10 years. The first patient is estimated to be enrolled in January 2021, while the last patient is expected to be completed in January 2031.

This is a retrospective and prospective registry. Since no intervention is foreseen, it can be considered an observational study.

The primary objective is to understand the clinical implications of mastocytosis, including the natural course of the disease, treatments and outcomes, variability in medical care, and disease burden.

Secondary objectives:

  • To estimate the prevalence, incidence, and clinical course of mastocytosis
  • To provide clinicians with prospective data to assist in the clinical management of individual patients
  • To systematically collect data that can be integrated with data from other studies to support aggregate and comparative analyses.

Approximately 1,500 patients already treated at participating centers will be enrolled.

It is estimated that approximately 250-300 new patients will be included in the registry each year.

Patients ≥18 years of age and diagnosed with mastocytosis will be included in the study.

Each participant must be able to provide written informed consent to be enrolled.

There are no exclusion criteria. Variables to be collected. The study objectives will be assessed through data collection of the clinical and biological variables collected.

Eligibility criteria

INCLUSION CRITERIA Age ≥ 18 years Diagnosis of mastocytosis according to current WHO criteria. Ability to give according to ICH/EU GCP, and national/local regulations.

EXCLUSION CRITERIA No exclusion criteria are expected.

Terms in these criteria, in plain language(1)

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.

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.
