The primary objective of this trial is to evaluate the safety of romosozumab in participants with osteogenesis imperfecta (OI) that have completed Study 20200105, regardless of whether they received investigational product (romosozumab) until the last protocol-specified dose or ended investigational product early.
NCT00076830
This study offers evaluation and treatment of patients with a suspected connective tissue disorder. The protocol is not designed to test new treatments; rather, patients receive standard care. The study is designed to: 1) allow NICHD's staff to learn more about connective tissue disorders, 2) train physicians in the evaluation and treatment of these disorders; and 3) establish a pool of patients who may be eligible for other NICHD protocols for connective tissue disorders. (Participants in this protocol will not be required to join another study; the decision will be voluntary.) Patients of all ages with a suspected connective tissue disorder and their unaffected family members may be eligible for this study. Participants undergo diagnostic procedures that may include a medical history, physical examination, X-ray studies, eye examinations, and blood drawing, as well as other specialized tests, when needed. Additional tests may include: * Blood test for DNA genetic analysis * Skin biopsy: Removal of a small piece of tissue for microscopic examination. The area of skin selected for the biopsy is numbed and a small circle of skin, usually from the upper arm, is removed with a surgical cookie cutter-like instrument. * Magnetic resonance imaging (MRI): This test uses a strong magnetic field and radio waves to show structural and chemical changes in tissues. The patient lies on a table that slides into a narrow cylinder containing a magnetic field. Ear plugs are worn to muffle loud knocking and thumping sounds that occur with electrical switching of the magnetic fields. * Computed tomography (CT) scans: This test allows the doctor to view the organs inside the body in small sections. The patient lies in a doughnut-like machine. Scanning can be done from different angles, allowing a three dimensional picture of the part of the body being studied. It may be done with or without injection of a contrast material. * Referral to appropriate sub-specialists when potential complications are found.
NCT00001594
We propose a longitudinal study of the natural history of types III and IV osteogenesis imperfecta for children age birth to 25 years. A consistent objective throughout this study is to obtain a comprehensive assessment of the natural history and progression of the multiple secondary features of osteogenesis imperfecta. In addition to radiographic, bone density, physical rehabilitation and dental manifestations, we will assess the cardiovascular, pulmonary, neurological, and audiology systems. The major objectives of this protocol focus on rehabilitation and physical therapy studies, pulmonary and cardiovascular function, neurological features, audiological studies and genetic and molecular biology aspects of OI. A major objective in this study is to expand the intensive rehabilitation and physical therapy studies of children with types III and IV OI. This objective continues the work that has been done in the Rehabilitation Department of the Clinical Center for the past 20 years on these patients. However, the focus of this objective is changing to include studies of scoliosis and its effect on function, studies of chest proportions and rib deformities, and studies of nonkinetic variables related to motor performance, such as temperament, competence, coping, and resilience in children with OI. The second major objective is the longitudinal study of pulmonary function in children with types III and IV OI. It is well known that cardiopulmonary complications are a major cause of disability and death in adults with OI; the developmental patterns of these complications, and whether susceptible individuals can be identified in childhood, is unknown. The third major objective of these studies of secondary features is to determine the incidence of basilar invagination and develop a monitoring and management plan for this neurological feature. Next, the prevalence, severity, age of onset and genotypic/phenotypic correlation of hearing loss among children with types II and IV OI remains poorly understood; therefore, the study of audiological features is our fourth major objective. The final major objective in this study is the continued study of the genetic and molecular biology aspect of OI. Patients will have skin biopsies for collagen studies at the biochemical and molecular level. Parents will have blood drawn for determination of mosaic status for the mutation that causes their child s OI. These studies will provide further information on genotype/phenotype correlation and other variables in OI genetics. As appropriate, bone chips from emergency or elective surgical procedures on the participants will be used to study osteoblast function in OI.
NCT05317637
Osteogenesis imperfecta (OI) is a group of congenital and heritable bone disorders that currently affects at least 50,000 people in the United States. OI varies in severity from perinatally lethal to mild forms. The majority of cases is caused by a dominant mutation in type I collagen genes (COL1α1 and COL1α2), altering the quantity or quality of type I collagen. Although OI is typically characterized as a disease of the bone, it is perhaps more accurately described as a connective tissue disorder. Type I collagen is a major constituent of lung connective tissue. Respiratory insufficiency is the leading cause of death in patients with OI. Thus, it is important and necessary to understand the etiology of the restrictive pulmonary physiology in the OI population.
NCT07412782
This study evaluates bone mineral density (BMD) in pediatric patients aged 5-18 years with conditions negatively affecting bone health, using REMS (Radiofrequency Echographic Multi Spectrometry), a non-invasive and radiation-free ultrasound technology. Bone health is crucial during childhood, when peak bone mass develops, and reduced BMD is associated with increased fracture risk. DXA is the current reference method but has limitations in children, including radiation exposure and growth-related measurement issues. REMS has been validated in adults and shows promise in pediatrics, despite the lack of reference values. The study is a single-center, national, non-profit interventional study lasting about 12 months. Participants will undergo REMS BMD measurement, clinical history collection, and assessment of anthropometric and pubertal parameters, with prior DXA data collected when available. The primary aim is to describe BMD values measured by REMS in pediatric osteoporosis, with secondary aims including subgroup analyses and comparison with DXA. A sample of 100 patients is planned. Statistical analyses will assess BMD distributions, correlations with clinical variables, and agreement between REMS and DXA using correlation coefficients and Bland-Altman analysis.
NCT04152551
Osteogenesis Imperfecta-related hearing loss usually occurs in individuals with mild (type I) OI and is much earlier in onset than age-related hearing loss, with the majority of individuals experiencing some minor hearing loss in their 20s. Bisphosphonates have been successfully used to treat otosclerosis, a common cause of hearing loss similar to OI-related hearing loss. As many individuals with OI-related hearing loss also present with otosclerosis and because of their mechanistic similarities, the investigators propose studying the effects of bisphosphonate treatment on individuals diagnosed with both OI type I and hearing loss, thereby determining its effectiveness as a potential treatment for hearing loss. The investigators will enroll 50 individuals diagnosed with type I OI and age 18-100. 25 adults will be enrolled into the treatment arm and receive bisphosphonate treatment (must have at least mild hearing loss), while 25 adults will be enrolled into the control arm. The investigators will enroll 25 children (6-17 years of age) diagnosed with OI who are currently receiving bisphosphonate treatment as part of their care for orthopedic symptoms. The investigators will also observe 25 children (6-17 years of age) diagnosed with OI who are NOT currently receiving bisphosphonate treatment. The study duration is 63 months (approximately 5 years). Enrollment is anticipated to begin in November 2019.
NCT05559801
This is a Phase 1/2 study to determine the safety and efficacy of allogeneic (third party), bone-marrow derived mesenchymal stromal cells (MSCs) for the treatment of Osteogenesis Imperfecta (OI) Type 3. It will evaluate this by looking at whether there are treatment related infusion reactions, and assessing linear growth rates and bone health, both of which are impaired in patients ages 3-10 with Osteogenesis Imperfecta Type 3. This is a single-site non-randomized clinical trial, that will take place at Children's Healthcare of Atlanta (CHOA) at Egleston and Emory Children's Center.
NCT03735537
Osteogenesis imperfecta (OI) is an inherited skeletal disorder characterised by increased risk of fragility fractures. Bisphosphonates are frequently prescribed for adult patients with OI with the aim of preventing fractures but the evidence base for efficacy is poor. Recent evidence suggests that the bone anabolic agent teriparatide (TPTD) increases bone mineral density (BMD) and may have the potential to prevent fractures in OI. The purpose of the TOPaZ Trial is to investigate if a a two-year course of teriparatide (TPTD) followed by antiresorptive therapy with a single infusion of zoledronic acid (ZA) in adults with OI reduces the proportion of patients who experience a fracture as compared with standard care Adult patients with a clinical diagnosis of OI who are willing and able to give informed consent and who do not have contraindications to the study medications will be recruited from participating sites. Participants will be randomised 1:1 to receive either standard care for the duration of the trial or TPTD for 24 months followed by a single infusion of ZA, or another antiresorptive agent in the event that ZA is contraindicated. Participants will attend recruiting centres for a Baseline/Screening visit, at 12 months, 24 months and at the end of the trial for formal study visits with telephone calls every 6 months from a site research nurse. Participants randomised to TPTD will also attend recruiting centre at regular intervals during the 24 month treatment period to collect new supplies of TPTD.

NCT05231668
SAR439459 is a human anti-Transforming growth factor β (TGFβ) monoclonal antibody. This phase 1 clinical study investigates the safety, tolerability, and activity of a single dose of SAR439459 in adult participants with OI. Participants will receive a single IV dose of SAR439459 with safety, pharmacokinetic (PK), and pharmacodynamic (PD) assessments over 24 weeks. There will be up to 3 dose cohorts. In addition to safety, tolerability, and PK assessments, bone mineral density (BMD) will be evaluated by dual-energy Xray absorptimetry (DXA) scan and a series of blood biomarkers will be monitored to document pharmacodynamic effects of the single dose of SAR439459.
NCT04119388
Osteogenesis imperfecta (OI) is a rare genetic disorder of increased bone fragility and low bone mass. It is conceivable that children and adolescents with OI are less active than healthy peers because of frequent fractures, immobilization,functionals limitations and no adapted physicals activity(APA). The hypothesis is that an Adapted physique activity could improve access of activity for patients with Osteogenesis Imperfecta (OI). The aim of the study is to evaluate benefice of APA,improve aerobic capacity, cardiovascular and bone benefits, and gain of quality of life. Children with OI between 6 and 18 years old will have a program of supervised "adapted training program" during one year. The program is adapted at each individual and without risk for the patient.
NCT05312697
The primary objective of the study is to evaluate bone mineral density (BMD) after 12 months of retreatment with monthly setrusumab in adults with osteogenesis imperfecta (OI).
NCT04169568
Osteogenesis Imperfecta (OI) is a genetic disorder caused by mutations to the alpha-1 or alpha-2 chain of type I collagen. Clinically, the disorder is characterized by bones that fracture easily, often from little or no apparent trauma. There is no information about Some institutions perform blood pressure monitoring on these patients with a cuff, while other institutions avoid this method due to concern for fracture. Instead, they use alternative forms of monitoring such as an arterial line. These methods come with their own risks, including clotting, decreased perfusion, and pain. In addition, arterial lines require intensive (and more expensive) monitoring in a pediatric intensive care unit due to risk of dislodgement and rapid blood loss. These blood pressure monitoring recommendations for patients with OI do not appear to be based on strong evidence. Anecdotally, some patients and healthcare professionals report hearing about individuals with OI who have suffered fractures from blood pressure cuffs. However, this is not well documented in the medical literature. Regular and accurate blood pressure monitoring is particularly important in the postoperative period, due to blood loss and fluid shifts, as well as utilization of advanced pain management techniques that can potentially impact blood pressure.
