NCT ID: NCT05966064 Recruiting - Fibrous Dysplasia Clinical Trials

DEnosumab for the Treatment of FIbrous Dysplasia/McCune-Albright Syndrome in Adults (DeFiD)

DeFiD
Start date: June 13, 2023
Phase: Phase 4
Study type: Interventional

Fibrous Dysplasia/McCune-Albright syndrome (FD/MAS) is a rare disease, consisting of the replacement of normal bone tissue with fibrous tissue. FD lesions may be isolated in one or more bones or may be associated with endocrinopathies in McCune-Albright syndrome. Bone lesions constitute of weak bone tissue, leading to higher risk of fractures, pain and decreased quality of life. There is no cure for FD lesions and current therapies failed to soothe patients' complaints or to display any effect on progression of the lesions on imaging. However, the RANKL-inhibitor Denosumab demonstrated encouraging results in mouse models and in off-label clinical use, leading to clinical, biochemical and radiographical improvements. Study's aim is to investigate whether 3-monthly Denosumab will improve the clinical, radiological and biochemical manifestations of FD bone lesions.

Fibrous Dysplasia, McCune-Albright Syndrome Patient Registry

Start date: October 31, 2016
Phase:
Study type: Observational [Patient Registry]

The FD/MAS Patient Registry is an IRB-approved research study that that invites the patients and families to help answer some of the biggest questions about FD/MAS by completing questionnaires about their lives with FD or MAS. Have you enrolled in the FD/MAS Patient Registry yet? Are you up-to-date on your surveys? Take a trip to www.fdmasregistry.org today to learn more about the project, enroll, complete your surveys, or make sure you aren't due to provide more info!

NCT ID: NCT00001727 Recruiting - Clinical trials for McCune-Albright Syndrome

Screening and Natural History of Patients With Polyostotic Fibrous Dysplasia and the McCune-Albright Syndrome

Start date: December 13, 1998
Phase:
Study type: Observational

Polyostotic fibrous dysplasia (PFD) is a sporadic disorder which affects multiple sites in the skeleton. The bone at these sites is rapidly resorbed and replaced by abnormal fibrous tissue or mechanically abnormal bone. PFD may occur alone or as part of the McCune-Albright Syndrome (MAS), a syndrome originally defined by the triad of PFD, cafe-au-lait pigmentation of the skin, and precocious puberty. The bony lesions are frequently disfiguring, disabling and painful, and depending on the location of the lesion, can cause significant morbidity. Lesions in weight-bearing bones can lead to disabling fractures, while lesions in the skull can lead to compression of vital structures such as cranial nerves. The natural history of this disease is poorly described and there are no clearly defined systemic therapies for the bone disease. This is a data collection and specimen acquisition protocol. The purpose of the study is to define the natural history of the disease by following PFD/MAS subjects over time and by using in vitro experimentation with samples/tissue from subjects with the disease. Study Objectives 1. Primary Objective Define the natural history of disease by gaining clinical and basic information about PFD/MAS by following subjects clinically and using in vitro experimentation with tissue from subjects with the disease. 2. Secondary Objective Refer eligible subjects for enrollment into other appropriate research protocols, if any are currently active. Study Population The study population will include: 1. Subjects with known or suspected Polyostotic Fibrous Dysplasia (PFD) or in combination with McCune-Albright Syndrome (MAS) 2. Subjects who meet eligibility criteria will be accepted regardless of gender, race, or ethnicity Design This study is an observational/natural history study of PFD/MAS. Outcome Measures Primary 1. Successfully enroll subjects with PFD or MAS for the collection, evaluation and analysis of data obtained from clinical visits. 2. Obtain onsite and offsite research tissue (waste tissue) from patients with PFD/MAS that are enrolled onto this study or from individuals with PFD/MAS that are offsite and willing to donate waste tissue to NIH. Research tissue will be used with existing primary cell culture technology (ongoing in our laboratories) to: - understand the basic bone biology of the pathologic cell (or cells) involved in the lesions of PFD/MAS - determine the presence or absence of mutated cells at "uninvolved sites" to formulate better strategies of predicting the initiation of new lesions, the natural history of lesion progression and/or response to therapy - understand osteogenic differentiation, in particular, the role of G(s)alpha in these lesions, which will be transferable to our understanding of bone biology in general - understand the pathophysiology of FD and/or endocrine lesions - develop better methods of identifying and expanding unaffected bone cells from patients with PFD in an effort to create better grafting material(s) 3. Identify and predict clinical and biological behavior of fibrous dysplastic bone lesions based on: - stability, rate of growth, rate of change, progression and regression, and development of new lesions - differences between cranial, axial and appendicular lesions 4. Define the natural history of the multiple endocrinopathies associated with MAS and the response to standard of care medications 5. Define clinical and biological aspects of the disease not previously identified 6. Generate future research studies related to PFD alone or in combination with MAS Secondary 1) Successfully enroll eligible subjects into active research protocols applicable to the FD/MAS population....
