LONDONandNEW YORK, Sept. 22, 2020 (GLOBE NEWSWIRE) -- MeiraGTx Holdings plc(Nasdaq: MGTX), a vertically integrated, clinical stage gene therapy company, today announced nine-month results from the ongoing Phase 1/2 clinical trial(NCT03252847) of AAV-RPGR, an investigational gene therapy for the treatment of X-linked retinitis pigmentosa (XLRP), will be presented in an oral session at the EURETINA 2020 Virtual Meeting taking place October 2-4, 2020.
Details of the presentation are listed below. Data is embargoed until the date and time of presentation.
Title: Phase 1/2 Clinical Trial of AAV-RPGR Gene Therapy for RPGR-Associated X-Linked Retinitis Pigmentosa: 9-month ResultsPresenter: Michel Michaelides, BSc MB BS MD(Res) FRCOphth FACSDate and Time: Saturday, October 3, 10:45am EDT (4:45pm CEST)Session: EURETINA Session 11: Late Breaking & Reviews
MeiraGTx and Janssen Pharmaceuticals, Inc. (Janssen), one of the Janssen Pharmaceutical Companies of Johnson & Johnson, are jointly developing AAV-RPGR as part of a broader collaboration to develop and commercialize gene therapies for the treatment of inherited retinal diseases.
In July 2020, MeiraGTx announced six-month data from the ongoing Phase 1/2 MGT009 clinical trial, which demonstrated AAV-RPGR was generally well tolerated and produced significant improvement in vision in the dose escalation phase of the trial.
About AAV-RPGRAAV-RPGR is an investigational gene therapy for the treatment of patients with X-Linked Retinitis Pigmentosa (XLRP) caused by mutations in the eye specific form of theRPGRgene (RPGRORF15). AAV-RPGR is designed to deliver functional copies of theRPGRgene to the subretinal space in order to improve and preserve visual function.MeiraGTxand development partner Janssen are currently conducting a Phase 1/2 clinical trial of AAV-RPGR in patients with XLRP with mutations inRPGRORF15. AAV-RPGR has been granted Fast Track and Orphan Drug designations by theU.S. Food and Drug Administration(FDA) and PRIME, ATMP and Orphan designations by theEuropean Medicines Agency (EMA).
About the Phase 1/2 MGT009 Clinical TrialMGT009 is a multi-center, open-label Phase 1/2 trial (NCT03252847) of AAV-RPGR gene therapy for the treatment of patients with XLRP associated with disease-causing variants in theRPGRgene. MGT009 consists of three phases: dose-escalation, dose-confirmation, and dose-expansion. Each patient was treated with subretinal delivery of AAV-RPGR in the eye that was more affected at baseline. The patients other eye served as an untreated control. In dose-escalation (n=10), adults were administered low, intermediate, or high dose AAV-RPGR. The primary endpoint was safety. Visual function was assessed at baseline, three, six, nine and 12 months with Octopus 900 full-field static perimetry and mesopic fundus-guided microperimetry (MP); mean retinal sensitivity, visual field modeling and analysis (VFMA; Hill-of-vision volumetric measure), and pointwise comparisons were examined.
About X-Linked Retinitis Pigmentosa (XLRP)XLRP is the most severe form of retinitis pigmentosa (RP), a group of inherited retinal diseases characterized by progressive retinal degeneration and vision loss. In XLRP, both rods and cones function poorly, leading to degeneration of the retina and total blindness. The most frequent cause of XLRP is disease-causing variants in theRPGRgene, accounting for more than 70% of cases of XLRP, and up to 20% of all cases of RP. There are currently no approved treatments for XLRP.
AboutMeiraGTxMeiraGTx(Nasdaq: MGTX) is a vertically integrated, clinical stage gene therapy company with six programs in clinical development and a broad pipeline of preclinical and research programs.MeiraGTx has core capabilities in viral vector design and optimization and gene therapy manufacturing, as well as a potentially transformative gene regulation technology. Led by an experienced management team,MeiraGTxhas taken a portfolio approach by licensing, acquiring and developing technologies that give depth across both product candidates and indications. MeiraGTxs initial focus is on three distinct areas of unmet medical need: inherited retinal diseases, neurodegenerative diseases and severe forms of xerostomia. Though initially focusing on the eye, central nervous system and salivary gland,MeiraGTxintends to expand its focus in the future to develop additional gene therapy treatments for patients suffering from a range of serious diseases.
