Janssen to Highlight Innovation in Retinal Pipeline at the Association for Research in Vision and Ophthalmology (ARVO) 2023 Annual Meeting

Important new data on Janssen's investigational gene therapy portfolio, including botaretigene sparoparvovec (bota-vec) and JNJ-1887, will be presented

RARITAN, N.J., April 21, 2023 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that five company-sponsored presentations will be featured during the Association for Research in Vision and Ophthalmology (ARVO) 2023 Annual Meeting in New Orleans from April 23-27, 2023. Janssen presentations will include updates from the Phase 1/2 MGT009 trial for investigational gene therapy botaretigene sparoparvovec (bota-vec, formerly AAV-RPGR) in patients with the inherited retinal disease (IRD) X-linked retinitis pigmentosa (XLRP) associated with the retinitis pigmentosa GTPase regulator (RPGR) gene, and pooled safety analysis data from two Phase 1 trials of the investigational gene therapy JNJ-81201887 (JNJ-1887); one trial in patients with geographic atrophy (GA), a late-stage and severe form of age-related macular degeneration (AMD) and one trial in wet AMD (Abstracts #5446 and #732-C0314).^1,2

"People living with retinal diseases, including XLRP and geographic atrophy, are often faced with the inevitable fate of going blind. In this new era of innovation, we're taking a cutting-edge approach to saving sight through groundbreaking technologies such as gene therapy, and we're thrilled to showcase some of this research at this year's ARVO annual meeting," said James List, M.D., Ph.D., Global Therapeutic Area Head, whose team oversees a portfolio of programs including Retina at Janssen Research & Development, LLC. "We are on a bold mission to restore and preserve vision for people living with retinal diseases, and these important data bring us one step closer to building a brighter future for the patients we serve."

XLRP is a rare condition estimated to impact one in 40,000 people globally.^3,4 People with XLRP have progressive vision loss, starting in childhood with night blindness.⁵ Over time, they lose their peripheral vision followed by central vision loss leading to legal blindness by the average age of 40.⁵ Currently, no treatments are approved for XLRP.⁵ Geographic atrophy is an advanced form of AMD.⁶ It affects more than five million individuals worldwide and is a leading cause of blindness in people over 65 years of age.⁶ It has a devastating impact on these patients and their quality of life, including their ability to read, drive and perform other day-to-day activities.⁶

A complete listing of Janssen-sponsored abstracts being featured at the ARVO Annual Meeting is provided below. Abstracts can also be found on the ARVO Annual Meeting website.

Janssen will also have an interactive Retina Medical Affairs exhibit booth (location #709) at the ARVO annual meeting. For more information about Janssen Retina's research and portfolio, please visit www.retina.janssen.com.

About botaretigene sparoparvovec (bota-vec)
Botaretigene sparoparvovec (bota-vec) is being investigated in collaboration with MeiraGTx Holdings plc for the treatment of patients with X-linked retinitis pigmentosa (XLRP) caused by disease-causing variants in the eye-specific form of the RPGR gene. Through a one-time administration, bota-vec is designed to deliver functional copies of the RPGR gene to counteract the loss of retinal cells with the goal of preserving and potentially restoring vision for those living with XLRP. The Phase 3 LUMEOS clinical trial (NCT04671433) is actively dosing patients to study bota-vec for the treatment of patients with XLRP with disease-causing variants in the RPGR gene. Bota-vec has been granted Fast Track and Orphan Drug designations by the U.S. Food and Drug Administration (FDA) and PRIority MEdicines (PRIME), Advanced Therapy Medicinal Product (ATMP) and Orphan designations by the European Medicines Agency (EMA).

About the Janssen and MeiraGTx Strategic Collaboration
In January 2019, Janssen Research & Development, LLC entered into a worldwide collaboration and license agreement with MeiraGTx Holdings plc, a clinical-stage gene therapy company, to develop, manufacture and commercialize its clinical-stage inherited retinal disease portfolio. Botaretigene sparoparvovec (bota-vec) is being developed as part of a collaboration and license agreement. In addition to forming a research collaboration to explore new targets for other inherited retinal diseases, Janssen is working with MeiraGTx to build core capabilities in viral vector design, optimization and manufacturing.

About JNJ-1887
JNJ-81201887 (JNJ-1887), formerly referred to as AAVCAGsCD59, is an investigational one-time gene therapy for the treatment of people with geographic atrophy, an advanced form of age-related macular degeneration (AMD). JNJ-1887 is designed to increase the expression of a soluble form of CD59 (sCD59) intended to protect retinal cells, thus slowing and preventing disease progression. The Phase 2b PARASOL clinical trial (NCT05811351) is actively enrolling patients to study JNJ-1887 for the treatment of adults 60 or older with advanced dry AMD with geographic atrophy. JNJ-1887 has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) and Advanced Therapy Medicinal Product (ATMP) designation by the European Medicines Agency (EMA).
