Deciphering Antitumour Response and Resistance With INtratumour Heterogeneity
University College, London
DARWIN II is a multi-arm non-randomised phase II trial, Eligible patient will be those who relapse with NSCLC (clinical trials.gov ref. NCT02183883). . The trial will investigate assess if intra-tumour heterogeneity (clonal vs subclonal actionable mutation) is associated with PFS. Patients without an actionable mutation will receive MPDL3280A (atezolizumab), a monoclonal antibody targeting anti-PDL1, as monotherapy or in combination with chemotherapy, The options for combination therapy will vary depending on the histology of the NSCLC (i.e. non-squamous or squamous). Patients with BRAFV600 mutations, HER2 Amplification, ALK/RET gene rearrangements will be enrolled into arms treating with vemurafenib, trastuzumab emtansine and alectinib respectively. DARWIN II will include extensive exploratory biomarker analysis to investigate a number of genomic and immune markers that may predict response to MPDL3280A (atezolizumab) and help guide future clinical trial design.

NCT03025763 - Network Of Clinical Research Studies On Craniosynostosis, Skull Malformations With Premature Fusion Of Skull Bones

Network Of Clinical Research Studies On Craniosynostosis, Skull Malformations With Premature Fusion Of Skull Bones
Icahn School of Medicine at Mount Sinai
Craniosynostosis (CS) is a common malformation occurring in ~4 per 10,000 live births in which the sutures between skull bones close too early, causing long-term problems with brain and skull growth. Infants with CS typically require extensive surgical treatment and may experience many perioperative complications, including hemorrhage and re-synostosis. Even with successful surgery, children can experience developmental and learning disabilities or vision problems. Most often, CS appears as isolated nonsyndromic CS (NSC). Of the several subtypes of CS, unilateral or bilateral fusion of the coronal suture is the second most common form of CS accounting for 20-30% of all NSC cases. The etiology of coronal NSC (cNSC) is not well understood, although the published literature suggests that it is a multifactorial condition. About 5-14% of coronal craniosynostosis patients have a positive family history, with a specific genetic etiology identified in >25% of cNSC cases, suggesting a strong genetic component in the pathogenesis of this birth defect. The causes for cNSC and its phenotypic heterogeneity remain largely unknown. An international team of investigators will generate large genomic and gene expression datasets on samples from patients with cNSC. State-of-the-art imaging, genetic, and developmental and systems biology approaches will be used to quantitatively model novel pathways and networks involved in the development of cNSC. Novel variant-, gene- and network-level analyses will be performed on the genomic data obtained from cNSC cases, their relatives, and controls to identify novel variants and genetic regions associated with cNCS. Quantitative, analytical, and functional validations of these predictions will provide insights into the etiology and possible therapeutic targets for CS and potentially other bone-related disorders.

NCT01721720 - Genetic, Brain Structure, and Environmental Effects on ADHD

Genetic, Brain Structure, and Environmental Effects on ADHD
National Human Genome Research Institute (NHGRI)
Background: - Attention deficit hyperactivity disorder (ADHD) is one of the most common and inheritable of all neuropsychiatric disorders. It causes problems with attention and impulse control. However, the genetic component of ADHD has not been fully studied, including how genes interact with the environment. Researchers want to study children and adults who have ADHD. They will look at how genetic, brain structure, and environmental factors affect ADHD in children and adults. Objectives: - To study genetic, brain structure, and environmental factors in ADHD in children and adults. Eligibility: - Individuals at least 3 years of age who have ADHD. Design: - Participants will be screened with a physical exam and medical history. - Participants will be interviewed about their ADHD. They will also complete behavior and psychological tests. Parents or guardians will complete the tests along with participants under 18 years of age. - Participants will provide saliva or blood samples. - Participants will also have imaging studies of the brain. - Participants under 25 years of age will return once a year to repeat the tests. Those over 25 years of age will have only the one set of tests. Those who are starting stimulant drugs and who are receiving behavioral treatment for the first time will also have another set of tests 12 weeks after the start of treatment.

NCT03276702 - Tumor Rebiopsy in Children and Adolescents With Recurrent or Progressive Solid Malignancies

Tumor Rebiopsy in Children and Adolescents With Recurrent or Progressive Solid Malignancies
St. Jude Children's Research Hospital
It has been shown that the genomic landscape of tumors can dramatically change at the time of disease progression. This suggests that therapies aimed at treating the tumor at diagnosis may not be relevant at the time of relapse. Obtaining fresh tissue at the time of relapse could facilitate the identification of potential targets that have developed through mutational evolution of the primary tumor and would provide an unprecedented opportunity to expand the library of patient derived xenografts (PDX) that are available for comprehensive preclinical testing in the setting of relapsed disease. The purpose of this observational study is to prospectively collect fresh tumor tissue from pediatric patients with solid tumors who have recurrent or progressive disease and submit this tissue for comprehensive genomic analysis using clinically available CLIA-certified platforms that include WGS, WES and RNAseq, and to assess the reasons for a patient and/or a parent for making a decision to proceed with or refuse a re-biopsy procedure in the presence of a recurrent or progressive solid tumor. The data obtained will be used to develop new novel therapies that incorporate new pharmacological agents in pediatric solid tumors. PRIMARY OBJECTIVES: - To prospectively collect fresh tumor tissue from pediatric patients with solid tumors who have recurrent or progressive disease and submit this tissue for comprehensive genomic analysis. - To assess the reasons a patient and/or a parent make the decision to proceed with or refuse a re-biopsy procedure in the presence of a recurrent or progressive solid tumor. SECONDARY OBJECTIVES: - To estimate refusal and acceptance rates for re-biopsy and the parental/patient attitudes towards a re-biopsy. - To estimate the incidence of complications associated with biopsy. - To estimate the percentage of procedures that fail to obtain adequate tissue for genomic analysis.

NCT02215928 - Genomic Profiling in Recommending Treatment for Patients With Metastatic Solid Tumors

Genomic Profiling in Recommending Treatment for Patients With Metastatic Solid Tumors
Stanford University
This research trial studies using genomic profiling to recommend anticancer treatment to patients with cancer that has spread beyond the original site of the tumor (metastatic cancer). Genomic profiling studies the deoxyribonucleic acid (DNA) of a tumor to detect genetic changes or abnormalities. This information can then be used to recommend treatments that may be more likely to result in a beneficial response. It is not yet known whether genomic profiling will detect abnormalities that can be used to make treatment recommendations and whether treatment based on genomic profiling is more effective than standard treatment.

NCT03186625 - Impact of Traditional Chinese Medicine on the Gut Microbiota-dependent Trimethylamine N-oxide

Impact of Traditional Chinese Medicine on the Gut Microbiota-dependent Trimethylamine N-oxide
Guangdong Provincial Hospital of Traditional Chinese Medicine
Recent studies highlight the participation of gut microbes in the pathogenesis of both atherosclerotic heart disease and its adverse thrombotic events. Trimethylamine N-oxide (TMAO) is a plasma metabolite shown to be formed through a metaorganismal pathway involving nutrient precursors abundant in a Western diet and the sequential action of gut microbiota. Numerous studies reveal an association between systemic TMAO levels and cardiovascular risks in a variety of stable cohorts. The purpose of this study is to evaluate the efficacy of traditional Chinese Medicine formular (Compound pseudo-ginseng granules ) on the level of TMAO for the patient with acute coronary syndrome(ACS) undergoing percutaneous coronary intervention. 80 patients with ACS would be randomly allocated into interventional group(IG) and control group(CG). The patients in the IG would be administered by oral Compound pseudo-ginseng granules (twice per day ) for 90 days and those in the CG would receive the placebo twice per day during the same period. All of subjects would be administered with standard therapy in accordance with AHA/ACC guideline for ST-elevation myocardial infarction(STEMI) and Non ST-elevation myocardial infarction(NSTEMI).The primary endpoint is the plasma level of TMAO at 90-day follow-up. The second endpoint is the level of lipid, score of The Seattle Angina, fecal DNA extraction and pyrosequencing.

NCT02628808 - Susceptibility Genes in Autism Spectrum Disorders

Susceptibility Genes in Autism Spectrum Disorders
Institut National de la Santé Et de la Recherche Médicale, France
The main objective of the study is to define, for Autism Spectrum Disorder, the extent of genetic variation in synaptic pathways that may be targeted for therapeutic development. For this purpose the investigators will take advantage of large, well-characterized cohorts of patients with Autism Spectrum Disorder for genetic screenings. Targeted sequencing of selected synaptic genes, previously associated with Autism Spectrum Disorder, will be carried out in these cohorts with deep coverage of coding regions and a strong focus on previously untested regulatory regions. Genomic data from Copy Number Variant, whole genome sequencing and exome sequencing, available for some of these patients, will be integrated in the overall analysis. The investigators will strongly emphasize the establishment of comprehensive genotype/phenotype correlations and set up an induced Pluripotent Stem Cells collection from selected patients with synaptic mutations for functional and expression analysis.

NCT02542670 - Genetic Variants of Selected Genes in Colo-Rectal Cancer Patients.

Genetic Variants of Selected Genes in Colo-Rectal Cancer Patients.
Sherief Abd-Elsalam
Colorectal cancers (CRC) are the third most common human malignancy, and are also the leading cause of cancer related deaths worldwide. Early detection of premalignant lesions such as adenomatous polyps has decreased the risk of CRCs; however, cases which are initially undetected and progress to advanced CRC with distant metastasis are still unfortunately incurable. The development of CRC is a complex and heterogeneous process arising from an interaction between multiple etiological factors, including genetic factors and environmental factors such as diet and lifestyle. The challenges are to understand the molecular basis of individual susceptibility to colorectal cancer and to determine factors that initiate the development of the tumor, drive its progression, and determine its responsiveness or resistance to antitumor agents. Next generation sequencing(NGS)-driven genomic studies are already reporting novel features of cancer genomes beyond the traditional mutational categories. Recent advance in sequencing technology has enabled comprehensive profiling of genetic alterations in CRC.These methods are facilitating an increase in the efficiency and resolution of detection of each of the principal types of somatic cancer genome alterations, including nucleotide substitutions, small insertions and deletions, copy number alterations, chromosomal rearrangements,DNA methylation sequencing such as bisulfite-sequencing and microbial infections. Besides the microsatellite instability (MSI), some researchers reported novel mitochondrial mutations in the cancer genomes. NGS technology will help the investigators for understanding of entire CRC genomes and the obtained knowledge will lead to a better diagnosis and personalized targeted therapeutics for CRC management

NCT02534519 - Whole Genome Sequencing for Blood Group Genotyping and Definition as Exemplified on U- and St(a)+.

Whole Genome Sequencing for Blood Group Genotyping and Definition as Exemplified on U- and St(a)+.
Blood Donation Service Zurich, SRC
No health condition(s) are studied. Genetic background of blood groups is studied. U- and Stones(a)+ ("Caucasian type") are used as proof-of-principle samples. Disease associations of all blood group genes investigated are very rare, e.g. < 1 among 1'000 Swiss individuals (see table 1), and are not to be expected in the course of this study. Genomic DNA of 2 U- samples were both provided as blinded reference material from New York and Vienna blood centres, respectively. Both donors are lost for follow up, and although there is no documented evidence for refusal of the respective donors to use their material in research projects, samples still lack informed consent.

NCT03858777 - Cell Free DNA in Cardiac Sarcoidosis

Cell Free DNA in Cardiac Sarcoidosis
Nabeel Hamzeh
Sarcoidosis is a multisystem granulomatous disease of unknown cause that can affect any organ in the body, including the heart. Granulomatous myocarditis can lead to ventricular dysfunction and ventricular arrhythmias causing significant morbidity and mortality. Immunosuppressive therapy (IST) has been shown to reverse active myocarditis and preserve left ventricular (LV) function and in some cases improve LV function. In addition, IST can suppress arrhythmias that develop due to active myocarditis and prevent the formation of scar. The potential role of cardiac biomarkers, including brain natriuretic peptide (BNP), atrial natriuretic peptide (ANP), and cardiac troponins, in detecting active myocarditis is limited and studies have been disappointing. At present, there are no biomarkers to detect active myocarditis and the use of advanced imaging modalities (FDG-PET) for assessing and monitoring active myocarditis is not feasible or practical and is associate with high radiation exposure. As such, a biomarker that is reflective of active myocarditis and that is cardiac specific will assist physicians in assessing the presence of active myocarditis to guide therapeutic decisions and to assess response to therapy which can limit further cardiac damage. Cell free DNA (cfDNA) are fragments of genomic DNA that are released into the circulation from dying or damaged cells. It is a powerful diagnostic tool in cancer, transplant rejection and fetal medicine especially when the genomic source differs from the host. A novel technique that relies on tissue unique CpG methylation patterns can identify the tissue source of cell free DNA in an individual reflecting potential tissue injury. We will be conducting a pilot study to explore the utility of this diagnostic tool to identify granulomatous myocarditis in patients with sarcoidosis.

NCT02770339 - Pharmacogenomic Profiling of Pediatric Patients

Pharmacogenomic Profiling of Pediatric Patients
University of Alabama at Birmingham
The purpose of this study is to determine the proportion of children presenting to a pediatric emergency department with an acute mental health/behavioral crisis or clinical drug toxicity who have a "match" or "mismatch" between the genes for drug metabolizing enzymes and their current or recent drug therapy. The investigators will utilize a readily available and FDA-approved cheek swab DNA test --GeneSight®--in these children that categorizes patients into 3 different type of groups - RED, YELLOW, and GREEN based on individuals' abilities to metabolize psychotropic drugs . Specific objectives include: - The relationship of genomic mismatch to serum drug concentrations, either low or high - The proportion of children with a genomic mismatch who present to PED with intentional self-injury. - The relationship between match versus mismatch and self- and caregiver-reported outcomes of functioning, drug efficacy, and drug tolerability. - Examine the proportion of children/adolescents who present to PED with an adverse drug reaction to one or more psychotropic with a genomic mismatch. - Quantify the specific adverse reactions related to a mismatch of genotypes.

NCT02459743 - Molecular Disease Profile of Hematological Malignancies

Molecular Disease Profile of Hematological Malignancies
University of Pavia
In this prospective multicentric study, the University of Pavia together with the Fondazione IRCCS Policlinico San Matteo, Pavia and the IRCCS Fondazione Maugeri, Pavia, Italy will provide a systematic analysis of gene mutations in hematological malignancies by using NGS techniques. Patients with a conclusive diagnosis of haematological malignancies according to WHO criteria referred to the Rete Ematologica Lombarda clinical network (REL, www.rel-lombardia.net) will be enrolled. The investigators will analyse genomic DNA extracted from hematopoietic cells at different time points of patient disease. The study contemplates the use of molecular platforms (Next Generation Sequencing, NGS) aimed at the identification of recurrent mutations in myeloid and lymphoid neoplasms, respectively. Screening of gene mutations by NGS will be prospectively implemented in the context of REL clinical network. Patient samples will be analyzed at diagnosis and sequentially during the course of the disease at specific timepoints. The researchers will analyze the correlations between somatic mutations, specific clinical phenotypes (according to the WHO classification) and disease evolution. This will allow to: 1) identify new recurrent genetic mutations involved in the molecular pathogenesis of hematological malignancies; 2) define the role of mutated genes, distinguishing between genes which induce a clonal proliferation of hematopoietic stem cells, and genes which determine the clinical phenotype of the disease; 3) identify mutations which are responsible for disease evolution; 4) define the diagnostic/prognostic role of the identified mutations, and update the current disease classifications and prognostic scores by including molecular parameters. A systematic biobanking of biological material will be provided.
