Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

|Langerhans Cell Histiocytosis|
The majority and diversity of clinical manifestations in LCH are attributed to immunological dysfunction resulting from langerhans cell (LC) derived cytokine secretion both at the lesional and systemic level. In a recent study, Receptor Activator of Nuclear Factor Kappa-B Ligand (RANKL) was found to be abundantly expressed in cells within diverse LCH lesions from adult patients, especially in inflammatory infiltrates, a finding in line with a previously reported high osteoprotegerin (OPG) and low RANKL levels in the serum of patients with or without bone involvement. RANKL expression was associated with concomitant p65 Nuclear Factor Kappa-B (NFκB) nuclear staining, the main downstream effector of RANKL signaling, suggesting that lesional cell activation may be triggered locally by RANKL. Combining the serum and the lesional results, it can be inferred that there is an ongoing process of countervailing OPG production against lesional RANKL, which could be one of the self defense mechanisms among LCH patients. Therefore, the use of denosumab seems a rational treatment option in LCH in order to support and enhance the defensive OPG action and hopefully control or even interrupt the lesional immunological process. The primary study objective is to assess the therapeutic efficacy of denosumab 120 mg every 8 weeks (Q8W) sc in adult LCH patients. Secondary Objectives: 1. To define an uniform treatment approach for LCH patients with mild symptoms and low risk disease. 2. To explore the efficacy of denosumab 120 mg Q8W sc in reducing disease reactivations after treatment completion. 3. To illustrate the safety profile of denosumab in LCH patients. The primary efficacy endpoint is defined as the percentage of patients with progression of disease at Month 8.
