This study is a follow up to the HP-CD-CL-2002 clinical study. It evaluates the long-term safety in patients with Parkinson's disease after implantation of an investigational drug delivery system (DDS) with or without infusions of CDNF. All patients will have at least the port explanted.
A non-randomized, monocentric clinical study with a four month follow-up period , using a cord blood serum (CBS) eye drops in glaucoma patients. The purpose of the study analyzes whether the addition of CBS to hypotonic therapy is able to slow down the progression of anatomical and functional damage induced by glaucoma. The study evaluates the differences after two months of treatment as compared to baseline and after two-month from the end of the treatment.
Details regarding the degenerative spine disorders will be collected with a specific focus on the use of osteobiologics in treating degenerative conditions and their impact on fusion, as well as patient-reported outcomes for these conditions.
The purpose of the interventional study is to determine whether Nicotinamide is effective at upregulating the Frataxin (FXN) gene in patients with Friedreich's ataxia (FRDA) where this gene is abnormally 'switched off'. The purpose of the non-interventional study is to investigate the use of novel, highly-sensitive technology to capture clinical deficit and measure subtle changes in the activities of daily living and to correlate functional changes to levels of expression of Frataxin protein and the epigenetic structure of the Frataxin gene over a 9-12 month period without nicotinamide. Healthy volunteers will be included as comparators in this part of the study.
This pilot study will assess the feasibility of using heavy water as a safe 'tracer' for biomarker studies of diseases of the brain and spinal cord, that, together, are also called the central nervous system (CNS). Heavy water, also called deuterated water or D20, is the same as normal drinking water except the hydrogen atoms have been replaced by deuterium, a naturally occurring isotope of hydrogen. In particular, this study will use heavy water to define: 1) The rate of immune cell proliferation (growth) in the cerebrospinal fluid (CSF) compared to blood. This study will be examining a particular type of immune cell called T lymphocytes. 2) This study will also examine selected molecules generated by nerve cells of the CNS to understand their rate of secretion and turnover in healthy control participants, HIV-1-infected participants and participants with a non-HIV-related neurodegenerative disease such as Parkinson's disease (PD). This study will involve the administration of heavy water orally for either seven days, 12 days or six weeks. Measurements will be taken by lumbar puncture (LP, also known as a spinal tap). Blood (approximately five tablespoons per visit) will also be obtained at each of the lumbar puncture appointments. If this method can be used to establish the rates of immune cell turnover and the production rates of neuronal molecules using cerebrospinal fluid, it will provide unique data that is important to understand chronic neurodegenerative conditions, like PD, and to measure responses to targeted therapies. Hypothesis: 1. D2O, administered orally, can be used to measure the proliferation rates of CSF T cells (and, eventually, of their major phenotypic subsets). 2. D2O can be used to assess the turnover and production rates of CNS constituents that are normally or pathologically shed or secreted into the CSF, including (eventually): cargo molecules transported specifically in neurons in the CNS, such as chromogranin-A and -B, neuregulin-1 (specifically the extracellular secreted ectodomain of neuronal differentiation factor (NDF) isoform type α1, α2, β1, and the acetylcholine receptor inducing activity isoform (ARIA), secreted amyloid precursor protein (sAPP), alpha-synuclein; and APP metabolites amyloid beta (Aβ) 41 and 42.
This trial is a multicenter, unblinded, single-arm pilot study, lasting one year (plus one year extension Amendment n.3 25 August 2009, plus two years follow-up Amendment n.7) , to evaluate the efficacy and safety of the chelator therapy with deferiprone on cerebral iron accumulations. The drug will be administered in the dosage of 15 mg/kg twice daily. The safety and tolerability of the drug will be evaluated by measuring hemochrome every seven days with leukocyte formula count. At 3, 6 and 12 months from the start of treatment, a neurological evaluation will be performed using several specific evaluation scales (International Cooperative Ataxia Rating Scale (ICARS); Unified Parkinson's Disease Rating Scale (UPDRS); Burke-Fahn-Marsden (BFM)). Every 6 months of treatment, a brain magnetic resonance image (MRI) aimed at measuring iron overload quantitatively, if possible.
Human fibroblasts and possibly other human somatic cells may be reprogrammed into induced pluripotent stem (iPS) cells by the forced expression of transcription factors (1-5). The iPS cells seem to share many properties with human embryonic stem cells. Induced pluripotent stem cells potentially may be useful in the future as an unlimited source of cells for transplantation. The major goal of the project is to develop human iPS cells from cell cultures from skin biopsies or the patient's hair. The iPS cells will be developed primarily for modeling diseases and drug discovery as well as basic research, and for developing the technology that may eventually allow the use of iPS cells for future transplantation therapy. The iPS cells developed in the course of this application are not intended for use in transplantation therapy. Future development of iPS cells for clinical transplantation therapies will be subjected to the appropriate authorization by ethical and regulatory committees.
