Filter by:This is a Phase 2, randomized, placebo-controlled crossover trial to assess the safety and efficacy of NB-001 in children and adolescents with 22q11DS that manifest commonly associated neuropsychiatric conditions.
To evaluate the safety and tolerability of ZYN002 administered as a transdermal gel formulation, for up to 38 weeks, in patients ages 4 to < 18 years, in the treatment of 22q.11.2 Deletion Syndrome (22qDS).
Chromosome 22q11.2 deletion syndrome (22q11DS) is a neurogenetic condition associated with a high risk of psychiatric disorders, including schizophrenia spectrum disorders. This population is characterized by a specific neurocognitive profile and atypical brain development. Methylphenidate is a psychostimulant used in the treatment of attention deficit with/without hyperactivity (ADHD). Although ADHD is one of the most important co-morbidities in 22q11DS, affecting 35-45% of patients, to date only two studies have focused on quantifying the efficacy of this treatment in this population. The objective of this study is to quantify the improvement in cognitive performance as well as the differences in brain connectivity associated with the methylphenidate molecule in a population at risk of cognitive impairment and the development of schizophrenia.
The 22q11.2 microdeletion syndrome (22q11.2DS) is a rare disease with a psychiatric phenotype. Indeed, the diagnosis of schizophrenia is made in 5 to 10% of adolescents and 25 to 40% of adults carrying the 22q11DS. Thus, although this pathology has been able to provide a genetically homogeneous model for the study psychosis etiology, it is not currently possible to establish a link between genomic rearrangement and psychotic symptoms. However, this robust model of genetic vulnerability could provide us a lot of translational informations about schizophrenia genetics. To go furthermore, twin studies have provided us precious data for the study of hereditary diseases. Combining this two approaches, the translational 22q11.2 project proposes a molecular study of two monozygotic 22q11.2DS twins discordant for the psychiatric phenotype -one carrying schizophrenia and the other having no psychiatric symptoms-.
This is a 5-week, multi-center, open-label, dose optimization trial in subjects aged 12-17 years with 22q11DS who have a diagnosis of anxiety disorder, and/or ADHD, and/or ASD. Approximately 12 subjects will be initiated, dose optimized, and maintained on NFC-1 over a period of 5 weeks.
22q11.2 microdeletion seems the prenatally under-diagnosed . Indeed , there is a mismatch between the series on the heart rate of 22q11.2 antenatal 84% against 30% in the adult series despite a perinatal mortality of 16% suggesting opportunities for improvement in the prenatal diagnosis of fetus with a microdeletion 22q11.2 , especially without heart disease
In January 2007, the American Congress of Obstetricians and Gynecologists (ACOG) revised its guidelines that now recommend physicians are ethically obligated to fully inform all pregnant women that screening for fetal chromosomal abnormalities including biochemical screening tests and invasive procedures such as CVS or amniocentesis is available, regardless of age. Further, it is entirely up to the patient to decide whether or not she wishes to be screened for fetal chromosomal abnormalities without judgment from the physician. Noninvasive laboratory-developed tests (LDTs) that detect an abnormal amount of maternal and fetal DNA in an expectant mother's blood sample (known as circulating cell-free DNA) are now available. These LDTs have not been cleared or approved by the U.S. Food and Drug Administration (FDA). Although LDTs to date have not been subject to U.S. FDA regulation, certification of the laboratory is required under the Clinical Laboratory Improvement Amendments (CLIA) to ensure the quality and validity of the test. To sample collection study will obtain whole blood specimens from pregnant subjects to be used for development of prenatal assays to assist in the screening for fetal genetic abnormalities, infectious and other diseases, and blood group typing through detection of circulating cell-free DNA extracted from maternal plasma.

This multi-center prospective observational study is designed to track birth outcomes and perinatal correlates to the Panorama prenatal screening test in the general population among ten thousand women who present clinically and elect Panorama microdeletion and aneuploidy screening as part of their routine care. The primary objective is to evaluate the performance of Single Nucleotide Polymorphism (SNP)-based Non Invasive Prenatal Testing (NIPT) for 22q11.2 microdeletion (DiGeorge syndrome) in this large cohort of pregnant women. This will be done by performing a review of perinatal medical records and obtaining biospecimens after birth to perform genetic diagnostic testing for 22q11.2 deletion. Results from the follow-up specimens will be compared to those obtained by the Panorama screening test to determine test performance. Specific test performance parameters will include: PPV, specificity, and sensitivity.
The goal of this study is to collect preliminary data on the efficacy of a cognitive remediation program in improving the neurocognitive deficits in children with chromosome 22q11.2 deletion syndrome (22q11DS). This study involves a two part approaching including a computerized cognitive remediation program (CCRP, Posit Science, CA) in combination with a Social Cognitive Training (SCT) program. The computer-based training program has shown encouraging results in improving learning deficits in individuals with schizophrenia and we now seek to adapt them to children with 22q11DS, who have unique needs due to their lower IQ and high risk of psychosis in late adolescence and adulthood. The SCT is a small-group intervention program based on cognitive enhancement therapy, which has been shown to improve social cognition and functionality in adults with schizophrenia. A preliminary study will be performed using this two-pronged approach, to establish the feasibility and gather preliminary data on neurocognition before and after the intervention in these children; these data would enable a larger randomized controlled study to assess the efficacy of this approach.
