Restoring muscle, rebuilding lives

ABOUT REGERNA

At Regerna Therapeutics, we are pioneering cutting-edge therapies to restore and regenerate functional muscle for patients suffering loss of muscle from injury, aging and dystrophies.

We are developing a new class of regenerative therapeutics that offer the potential to improve the lives of patients with muscle disorders.

Our mission is to bring life-changing therapies to patients living with conditions where muscle loss severely impacts quality of life.

SCIENCE

Regerna is pioneering a new class of regenerative medicines

RNA modulation is central to many diseases, where disruptions in RNA stability, splicing, or translation can lead to impaired gene expression and cellular dysfunction. RNA-binding proteins, which regulate these processes by recognizing specific RNA sequences, are dysregulated in many diseases. 

At Regerna, we are building a first-in-class RNA-binding proteins therapeutic platform to precisely correct these RNA defects.  Our lead therapeutic, AUF1, is a master controller of muscle repair and regeneration. 


Process Of Muscle Functional Recovery

AUF1 stabilizes and increases translation of muscle, mitochondrial, NMJ regeneration mRNAs
(e.g., PGC1-alpha, utrophin, and other key promoters)

AUF1 degrades mRNAs that inhibit muscle regeneration
(e.g., TNF-alpha, MMP9, Twist, and other key inhibitors)

Our lead mRNA Binding Protein, AUF1, is a Master Regulator of Muscle Repair and Regeneration

SCIENCE

AUF1 orchestrates and controls the full cascade of functional muscle regeneration - activating mitochondria, restoring neuromuscular junctions, and driving strength at the molecular level.

Impact of AUF1 Supplementation in Damaged or Dysfunctional Muscle

  • Increases muscle strength and endurance

  • Restores functional control

  • Reduces impact of injury and risk of further injury

  • Utrophin is a homolog that compensates for lack of dystrophin in DMD mice

  • Number and activity of mitochondria improved by AUF1 Boosts energy, activity and recovery of muscle

  • Maintains and builds ability to regenerate

Broad range of potential therapeutic indications

Societal problem: Loss or absence of functional muscle

A massive unmet need, leading healthcare economic burden and key driver of morbidity and mortality in aging and metabolic disorders.

Severe muscle loss, aging, injury, or atrophy

  • Sarcopenia is an age-related condition characterized by the progressive loss of skeletal muscle mass, strength, and function. This decline is driven by factors including reduced muscle protein synthesis, mitochondrial dysfunction, chronic inflammation, and decreased physical activity. As muscle fibers deteriorate, elderly individuals often experience reduced mobility, diminished endurance, and a heightened risk of injury and falls leading to hip fractures and, all too often, premature death. 

    Currently, there are no approved pharmacological treatments for sarcopenia. 

    Regerna’s programs are focused on restoring muscle mass and function by targeting key molecular pathways that are impaired with aging and are involved in muscle regeneration, mitochondrial biogenesis, and protein homeostasis. Though these unique compounds, we hope to offer a therapeutic approach to counteract age-related muscle degeneration.

  • Muscular dystrophies are a group of genetic disorders characterized by progressive muscle weakness and degeneration of the skeletal muscles. Over time, muscle fibers are replaced by fat and connective tissue, leading to decreased muscle function, reduced mobility, and premature death. Duchenne Muscular Dystrophy (DMD), a severe form of muscular dystrophy caused by the absence of dystrophin, affects approximately1 in 5,000 boys.

    Our lead program focused on DMD, REG-A40, comprised of the mRNA binding protein AUF1 delivered via AAV8 gene therapy, has demonstrated the ability to enhance muscle strength and endurance, promote muscle regeneration, and stimulate mitochondrial biogenesis. These effects are achieved because AUF1 increases utrophin, a paralogue of dystrophin, thereby restoring muscle stability and function.
