Gene therapy project about LGMD2E funded by GFB


2012

THE GENE THERAPY PROJECT FUNDED BY GFB STARTS

In 2012 the beta-sarcoglycan gene transfer project for treatment of Limb Girdle Muscular Dystrophy Type 2E had already been started at the Research Institute by Nationwide Children’s Hospital - Columbus Ohio.

Dr. J.R. Mendell and Dr. L. Rodino Klapac had started their work, the scientific way to be followed is based on their experiences, gained by completing a similar trial for the treatment, throughout a gene transfer therapy, of the Limb Girdle Muscular Dystrophy Type 2D.

Dr. Mendell explained in details aims and phases of the pathway to be followed:

Aim 1. Determination of pre-clinical efficacy of the transfer of human b-sarcoglycan gene, using recombinant adeno-associated virus to act as delivery vehicle, in b-sarcoglycan deficient mice. Time required: one year.

Aim 2. Regulatory preparation for a “recombinant adeno-associated virus human b-sarcoglycan” gene transfer intramuscular clinical trial, including formal toxicology/biodistribution study and clinical vector production. Time required: about one year.

Aim 3. Perform an intramuscular clinical gene therapy trial with recombinant adeno-associated virus human b-sarcoglycan transfer (into the “extensor digitorum brevis” muscle) in LGMD2E patients. Time required: about one year starting since the closing of the previous aim.

2015

THE SECOND STEP IS CONCLUDED

Currently the second phase of the project is finished. On August 2015 was published the first and the second steps of the project on Gene Theraphy magazine. Beta-Sarcoglycan gene transfer decreases fibrosis and restores force in LGMD2E mice .

TOWARDS THE CLINICAL TRIAL

On March, 17th GFB ONLUS took part to the congress Myology 2016 in Lyons, where we met Prof. Mendell. Present were Beatrice Vola (President of GFB), Marco Perlini (Vice President), Dr. Francesca De Santis (Polyclinic Hospital of Milan) and an interpreter.

SEPTEMBER 2016: Another big effort for the association with its offices in Talamona in the province of Sondrio. On Friday, 9th September GFB ONLUS sent another contribution to Columbus Ohio, of 202.500 $. From 2012 up to now we have financially supported the American laboratories with a total of 1.322.500 $. GFB is at the moment the only financier of the project.

On April 2017 was published the second article about  the Gene Therapy project.

"Systemic AAV-Mediated Beta-sarcoglycan Delivery Targeting Cardiac and Skeletal Muscle Ameliorated Histological and Funcional Deficits in LGMD2E Mice"

Myonexus Therapeutics Company is finally born - the journey towards the clinical trial

The aim of Myonexus Therapeutics Company, born in Columbus in May 2017, is to develop the gene therapy for Limb-girdle muscular dystrophy (LGMD) types 2B, 2C, 2D, 2E and 2L (within year 2027).
GFB Onlus is entered in the Myonexus. Our association, which represents one of the Company backers, sent on June 15th 2017 a total amount of 225.000 $. Together with GFB Onlus, both LGMD2D Foundation and KURT + PETER Foundation have contributed in this project as well.
Particularly, as regarding LGMD2E, two different clinical trials are planned, respectively for years 2017 and 2020; the last one (of 2020) will take place in Milan, too.

MAY 2018

GFB Onlus Announces that Myonexus, a Biotechnology Company in which it has Invested, Signed an Exclusive Partnership with Sarepta Therapeutics for the Advancement of Multiple Gene Therapy Programs Aimed at Treating Distinct Forms of Limb-Girdle Muscular Dystrophies

On May 3rd, 2018 Sarepta Therapeutics, Inc. (NASDAQ:SRPT), a commercial-stage biopharmaceutical company focused on the discovery and development of precision genetic medicine to treat rare neuromuscular diseases, and Myonexus Therapeutics, Inc., a clinical-stage biotechnology company developing transformative gene therapies for various forms of Limb-girdle muscular dystrophies (LGMDs), entered into an exclusive partnership to advance multiple gene therapy programs aimed at treating distinct forms of LGMDs.

GFB Onlus took part at the signing of this agreement between Sarepta and Myonexus, two biotechnology companies headquartered in the United States. GFB Onlus financed most of the pre-clinical work on MYO-101, the LGMD2E Gene Therapy.

FIRST PATIENTS ARE TREATED IN OCTOBER

Myonexus Therapeutics has announced the start of a systemic gene therapy clinical trial for Beta-sarcoglycanopathy, or LGMD2E. The first patient of the Trial was treated in October 2018 and all the patients of the first group will be treated in 2018, the first results will be announced in early 2019. Michael Triplett, president of Myonexus, has declared that Myo-101 can be the first complete therapy for LGMD2E patients. Myo-101 is the culmination of years of hard work and experiments, added Dr. Jerry Mendell.

FEBRUARY 2019

PRELIMINARY RESULTS ON TRIAL LGMD2E AND ACQUISITION OF MYONEXUS

On  February 27, Sarepta published preliminary results on the first gene therapy trial performed on patients with LGMD2E in Columbus Ohio, USA. Program in which the first three patients treated demonstrated the robust and widespread expression of the beta-sarcoglycan protein. Following these promising results Sarepta announced that it will acquire Myonexus Therapeutics.
