26 Clinical Trials for Various Conditions
The purpose of this study is to evaluate the safety, tolerability, and identify potentially effective dose(s) of TYRA-300 in children with achondroplasia with open growth plates.
This is an observational study of individuals with achondroplasia in the United States. The primary study population consists of pediatric individuals treated and untreated with VOXZOGO™. Study enrollment started in February 2023. The projected total duration of the study is approximately 5 years at minimum from start of study recruitment in February 2023, with the duration of individual prospective follow-up differing depending on the time of enrollment. The study duration may be extended based on decisions by the study sponsor. Data will be collected in two formats for the primary pediatric study population: 1. Participant-mediated access to electronic health records(including medical imaging, when available) which will enable retrospective and prospective collection of secondary data reflecting real-life treatment use and clinical care. . 2. Primary data collection of Clinical Outcome Assessments (COAs) and questionnaire data. Data will be collected in the following format for the adult cohort: - Participant-mediated access to electronic health records (including medical imaging, when available) which will enable retrospective and prospective collection of secondary data reflecting real-life treatment use and clinical care. The primary study population will include approximately 150 pediatric individuals with achondroplasia regardless of their treatment status with VOXZOGO™. Individuals may change status from untreated to treated during the prospective period of the study (or vice versa) however they will only be counted once, based on their treated status at the point of enrollment. The secondary study population will include 20 adolescent and adult participants.
This is a Phase 3, multicenter, double-blind, randomized, placebo-controlled study to evaluate the efficacy and safety of infigratinib in children and adolescents with achondroplasia (ACH) who have completed at least 26 weeks of participation in the QED-sponsored study PROPEL (QBGJ398-001).
This trial is a Phase 2, multicenter, double-blind, randomized (ratio 2:1 TransCon CNP vs. placebo), placebo-controlled trial, designed to evaluate the safety, tolerability, and efficacy of 100 μg CNP/kg of Navepegritide (TransCon CNP) administered SC once-weekly for 52 weeks in infants with genetically verified heterozygous ACH, aged 0 to \< 2 years at the time of randomization.
TransCon CNP administered once-weekly in children and adolescents with achondroplasia who have completed a prior TransCon CNP clinical trial. Participants who complete a prior TransCon CNP trial and meet all eligibility criteria will be invited to continue into the long-term open label extension trial to receive 100 µg CNP/kg/week of TransCon CNP. Trial treatment will be completed when the participant reaches 16 years of age for females and 18 years of age for males and have femur and tibial epiphyseal closure. TransCon CNP treatment will continue if femur and tibial epiphyseal closure is not confirmed at the age of 16 years for females, and 18 years for males. Treatment with TransCon CNP will be completed once femur and tibial epiphyseal closure is confirmed by radiographic imaging. The trial duration is individual for each trial participant. Visits will occur every 12-14 weeks throughout the trial.
The purpose of this study is to learn about the study medicine (called recifercept) in people with achondroplasia. Achondroplasia is a very rare disease and patients of achondroplasia have short arms and legs. The study will include data already collected from a recifercept clinical trial and data collected from a separate study of achondroplasia. This study will compare patient experiences and will help the investigators determine if the study medicine, recifercept, is effective.
The purpose of this clinical trial is to evaluate efficacy and safety of once weekly SC doses of 100 µg CNP/kg compared to placebo on Annualized Growth Velocity after a 52-week randomized treatment period in children aged 2 to 11 years with genetically confirmed Achondroplasia. The double-blind, placebo-controlled treatment period is followed by an Open Label Extension (OLE) period of a 52-week duration.
This is a Phase 2, multicenter, open-label, extension (OLE) study to evaluate the long-term safety, tolerability, and efficacy of infigratinib, an FGFR 1-3-selective tyrosine kinase inhibitor, in subjects with ACH who previously completed a QED-sponsored interventional study, and potentially in additional subjects who are naïve to infigratinib treatment. Quality of Life assessments for this subject population will also be evaluated. Treatment-naïve subjects must have at least a 6-month period of growth assessment in study QBGJ398-001 (PROPEL) and will be enrolled in this OLE study only after a dose to be explored further is identified in Phase 2 Study QBGJ398-201 and subjects are not otherwise eligible to enroll in another QED-sponsored Phase 2 or Phase 3 ACH study.
All participants who completed the prior study to assess long-term safety, tolerability, pharmacokinetics and efficacy, and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll in this open-label extension (OLE) study for up to an additional 24 months of treatment. Approximately 63 participants will be offered to continue at the previously received dose of Recifercept either Low Dose Medium Dose High Dose or at the therapeutic dose once it is identified. Participants will attend the clinic monthly for 24 months. Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements \& patient/caregiver quality of life questionnaires.
Approximately 63 participants will be randomized to one of three doses to receive Recifercept either * Low Dose * Medium Dose * High Dose Participants will will attend the clinic at baseline and at Day 1, 4, 8, 15, 29 \& then Month 2, 3 6, 9 \& 12. Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements \& patient/caregiver quality of life questionnaires Participants will received treatment with Recifercept for 12 months. All participants who complete the study and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll into an open-label extension (OLE) study. A PK cohort will include 12 participants who will randomly receive a single dose of 3 mg/kg of Phase 2 study (process 1c) formulation and a single dose of 3 mg/kg of the proposed Phase 3 (process 2) study formulation in a cross over study. Dose of the cohort could be changed due to emerging safety and efficacy data in the study.
This is a Phase 2, multicenter, open-label, dose-escalation and dose-expansion study to evaluate the safety, tolerability, and efficacy of infigratinib, a fibroblast growth factor receptor (FGFR) 1-3-selective tyrosine kinase inhibitor, in children 3 to 11 years of age with Achondroplasia (ACH) who previously participated in the PROPEL study (Protocol QBGJ398-001) for at least 6 months.

Achondroplasia and hypochondroplasia are the most common forms of dwarfism. Recent studies have shown that a small hormone called C-type natriuretic peptide (CNP) is an important regulator of linear growth. The investigators believe that genetic abnormality that causes achondroplasia and hypochondroplasia also disrupts CNP signaling, which may contribute to the growth problem. The investigators propose to look at levels of this and other closely related hormones in children and adults with achondroplasia or hypochondroplasia to see if they are different from levels in healthy people. The investigators hypothesis is that CNP levels are elevated in children with achondroplasia or hypochondroplasia, compared the healthy population. Another hypothesis is that CNP levels are not elevated in adults with achondroplasia or hypochondroplasia, since adults have no growth-plate cartilage. By studying the potential role of the CNP system in achondroplasia and hypochondroplasia, not only will the investigators provide further insight into the pathophysiology of these common syndromes, the investigators will also provide greater insight into the regulation of normal linear growth.
Since the gene responsible for achondroplasia was identified in 1994, it has become possible to test for achondroplasia prenatally. Moreover, prenatal genetic testing for achondroplasia is relatively simple and is highly likely to be informative for any couple seeking testing. Four diagnostic laboratories in the U.S. are currently performing prenatal genetic testing for achondroplasia. Before prenatal genetic testing for achondroplasia becomes more widely available, however, it is essential that we learn more about the lives of affected individuals and their families, the implications of offering testing for achondroplasia, and the education and the counseling needs of this community. Personal interviews and stories have been published and discussed at national meetings (Ablon 1984). We conducted a pilot telephone interview survey of 15 individuals with achondroplasia. What is needed now is a large scale quantitative study of the community of little people and their families. To meet this need, we have developed a survey tool to analyze family relationships, quality of life, tendencies toward optimism or pessimism, information-avoiding or information-seeking behaviors, social support, involvement in Little People of America Inc. (LPA), self-esteem, sociodemographics and views on achondroplasia, religiousness, reproductive and family plans, genetic testing, and abortion. The self-administered survey will be completed nationally by a sample of persons with achondroplasia and their family members.
The purpose of this study is to establish the bioequivalence of a single SC dose of BMN 111 administered using a vial and syringe versus using an injector pen.
The purpose of this study is to measure how much of the study drug gets into the blood- stream and how long it takes the body to get rid of it when given as a single dose. Information about any side effects that may occur will also be collected.
