Filter by:This is a Phase 2, Open-Label, Extension Study to Evaluate the Long-Term Safety, Tolerability, and Efficacy of BMN 111 in Children with Achondroplasia. The primary objective is to evaluate the long-term safety and tolerability of daily SC injections of BMN 111 in children with ACH who have completed two years of treatment in the 111-202 study.
The purpose of this study is to create an electronic registry to house phenotypic information from patients with achondroplasia. The initial focus of this registry will be to include U.S. patients with achondroplasia. Once populated, the collective data can be queried to pursue clinical research questions pertaining to health outcomes and treatment options for patients with this conditions. The registry is longitudinal in nature with the functionality to retrospectively enter patients' clinical data from the prenatal period up through the most recent encounter, with all intervening data entered in a chronologic fashion.
This is a Phase 2, open-label, sequential cohort dose-escalation study of BMN 111 in children with achondroplasia. The primary objective is to assess the safety and tolerability of daily BMN 111 administered to children with achondroplasia.
Multicenter, multinational study to collect consistent baseline growth measurements on pediatric patients with Achondroplasia being considered for subsequent enrollment in future studies sponsored by BioMarin. No study drug is administered.
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.
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.
This study is conducted in Japan. The aim of this study is to assess the incidence rate of adverse drug reactions (ADRs) when using somatropin (Norditropin®) for treatment of for achondroplasia without epiphyseal line closure under normal clinical practice conditions.
This study is conducted in Japan. The aim of the study is to evaluate the efficacy of somatropin (Norditropin®) on adult height (cm) in patients with achondroplasia / hypochondroplasia enrolled in the GH-1941 study (NCT01516229).
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.
