Epic Bio Presents Proprietary Gene Expression Modulation System (GEMS) Demonstrating Precise Engineering of DUX4 Gene in Facioscapulohumeral Muscular Dystrophy

SOUTH SAN FRANCISCO, Calif. – October 13, 2022 – Epic Bio, a biotechnology company developing therapies to modulate gene expression using compact, non-cutting dCas proteins, today announced a presentation on the company’s unique engineering platform, called the Gene Expression Modulation System (GEMS), at the co-hosted Solebury / BMO Fall Private Company Showcase.

“We are excited to show the scientific community a new approach to treating genetic and non-genetic diseases. Our dCas proteins anchor our GEMS platform and have been uniquely designed to work in tandem with our customized library of modulators (gene activators and suppressors),” said Amber Salzman, Ph.D., Chief Executive Officer of Epic Bio. “I am excited by the data we will present today on Facioscapulohumeral Muscular Dystrophy (FSHD), the second most prevalent form of muscular dystrophy. Notably, our in vitro results demonstrate the utility of our dCas to suppress DUX4 expression by up to 95%. We view this to be a tremendous step forward to finding a one-and-done treatment for this debilitating disease. Following on from this, we have submitted a request to the FDA for a pre-IND meeting to align on the IND submission package and Phase 1 clinical design.”

Epic Bio’s GEMS platform integrates its dCas proteins with customized guide RNA and modulator proteins to develop effective and safe approaches to treat diseases. Epic Bio’s dCas proteins are half the size of standard Cas9 proteins, thus enabling Epic Bio to deliver single AAV vectors to all tissues and organs.

About FSHD

Facioscapulohumeral Muscular Dystrophy is estimated to be the second most common muscular dystrophy, affecting 1 in 8,000 patients1,2. The genetic muscle disorder primarily affects the face, scapula, and the humerus region. The loss of movement is accompanied with chronic pain, anxiety, and depression. Symptoms usually start before age 20 and may lead to being wheelchair-bound by age 50. There are no treatment options for FSHD, and patients manage symptoms through the use of assistive devices, physical therapy, and orthopedics. For more information on FSHD, please visit
