5 Clinical Trials for Various Conditions
This study is to evaluate long-term safety, tolerability and efficacy for AFQ056 in patients who have completed an AFQ056A study in Parkinson's disease L-dopa induced dyskinesias (PD-LID).
This study will assess the efficacy and safety of modified release AFQ056 in patients that have Parkinson's Disease L-dopa Induced Dyskinesias (PD-LID)
Subjects stable on L-Dopa and oral ropinirole will have their ropinirole replaced with the Ropinirole Implant(s). The Ropinirole Implant was designed using the ProNeura™ implant technology where the implant is inserted under the skin. This study will measure how much ropinirole is released in the blood during 12 weeks of ropinirole implant treatment, and evaluate the side effects of this new formulation.
This application seeks renewed support for MH59803, "Dopaminergic substrates of startle gating across species," to extend a clear path of "bench-to-bedside" progress towards a critical paradigm shift in therapeutic models for schizophrenia (SZ) and schizoaffective disorder, depressed type (SZA): the use of Pharmacologic Augmentation of Cognitive Therapies (PACTs). This novel therapeutic strategy for SZ/SZA directly addresses the need for more effective treatments for this devastating disorder. MH59803 has investigated the neural regulation of laboratory-based measures of deficient information processing in SZ/SZA patients, using rodents and healthy human subjects (HS) to explicate the biology of these deficits, and to establish a rational basis for developing novel therapies for SZ/SZA. In its first 9 years, MH59803 studies of the neural regulation of prepulse inhibition (PPI) of startle in rats focused on basic neurobiological and molecular mechanisms. Over the past 2 years of support, MH59803 studies moved "from bench-to-bedside," focusing on dopamine (DA) agonist effects on PPI and neurocognition in HS, and their regulation by genes identified in cross-species studies. These studies detected biological markers that predict PPI-enhancing and pro-cognitive effects of the DA releaser, amphetamine (AMPH) in humans, leading to specific predictions of AMPH effects on PPI, neurocognition and Targeted Cognitive Training in SZ/SZA patients. If confirmed in the present application, these predictions could help transform therapeutic approaches to SZ/SZA. This renewal application of MH59803 thus reflects a logical progression of studies at systems and molecular levels, translated first to HS, and now to potentially transformative therapeutic models in SZ/SZA patients.
