Modis Therapeutics Announces Presentation at International World Muscle Society Congress 2018

Presentation by Dr. Michio Hirano on Mitochondrial DNA Depletion Disorders will Highlight Clinical Data on Treatment of Thymidine Kinase 2 Deficiency (TK2d) with Deoxynucleoside Therapy

Oakland, Calif., October 3, 2018 – Modis Therapeutics announced today that Dr. Michio Hirano, Professor of Neurology and Chief of the Division of Neuromuscular Medicine, Columbia University Irving Medical Center, has been invited to speak at the 23rd International Annual Congress of the World Muscle Society (WMS) which is being held October 2-6 in Mendoza, Argentina.

The invited lecture, “Deoxynucleoside Therapy for Mitochondrial DNA Depletion Disorders,” will be held during the Mitochondrial Disease II session from 11am to 12pm ART on October 4th.  The presentation will highlight clinical results of treatment of TK2d patients with deoxynucleoside therapy.  Modis Therapeutics is working with Dr. Hirano, Columbia University Irving Medical Center and a consortium of international collaborators to develop deoxynucleoside combination therapy, MT1621, for TK2d.  The data presented is part of a larger cohort being analyzed in a Modis sponsored study.

Dr. Carmen Paradas, Neurologist and Clinical Researcher in the Neuromuscular Diseases Unit at Hospital Universitario Virgen del Rocio and Instituto de Biomedicina de Sevilla, commented, “my colleagues and I have treated a number of TK2 patients and have found that deoxynucleosides provide clear clinical benefit in infantile, childhood and adult-onset patients as compared to the morbidity and mortality reported in two recently published natural history studies of TK2d.” 1,2

About TK2 Deficiency

Thymidine kinase 2 deficiency (TK2d) is a genetic disorder that results in mitochondrial dysfunction, leading to inadequate energy production in cells. TK2d may present at all ages and causes progressive and severe muscle weakness, respiratory insufficiency, and is often fatal. There are currently no approved therapies for this disease.
