February 6, 2024 updated by: Gruppo Italiano Malattie EMatologiche dell'Adulto

Langerhans Cell Histiocytosis in Adults: a Collaborative, Prospective-retrospective, Observational GIMEMA Study

This is a multicenter, retrospective and prospective, observational, no profit study including adult patients with LCH, diagnosed starting from January 2001 to two years after the first enrolled patient. Each patient will be followed up to one year after the last enrolled patient. Each patient will be followed up to one year after the last enrolled patient.This study plans to collect clinical information at the time of diagnosis and at various follow-ups to evaluate the efficacy of first-line therapies. Diagnostic and therapeutic data will be collected from routine clinical evaluations and laboratory and instrumental investigations carried out during clinical practice

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multicenter, retrospective and prospective, observational, no profit study including adult patients with LCH, diagnosed starting from January 2001 to two years after the first enrolled patient. Data from patients, diagnosed from January 2001 to the date of patient enrolment, is considered retrospective, while data collected after patient enrolment, and up to two years after the first enrolled patient, is considered prospective. At least one year of follow-up is expected for each patient. Each patient will be followed up to one year after the last enrolled patient. This study plans to collect clinical information at the time of diagnosis and at various follow-ups to evaluate the efficacy of first-line therapies. Diagnostic and therapeutic data will be collected from routine clinical evaluations and laboratory and instrumental investigations carried out during clinical practice. A sub-cohort of patients with available biological data on somatic mutations of the RAF-MEK-ERK genes will also be evaluated.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

adult patients with LCH, diagnosed starting from January 2001 to two years after the first enrolled patient.

Description

Inclusion Criteria:

  • Confirmed histological and immunohistochemical diagnosis of LCH (CD1a+, S-100+, CD207+), from January 2001 up to two years after the first enrolled patient. Patients with isolated vertebra plana, not related to a malignancy, and without a soft tissue component, are included without a histological and immunohistochemical diagnosis;
  • Age ≥18 years at the time of definitive diagnosis;
  • Signed, written informed consent, according to ICH/EU/GCP, and national, local laws.

Exclusion Criteria:

  • Age ≥18 years and presumptive diagnosis of LCH, or definitive diagnosis of non-Langerhans Histiocytosis (Juvenile xantogranuloma, Rosai-Dorfman disease, Erdheim-Chester disease, etc.).

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 15, 2021

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
