Summary of the technology
We are looking for a licensing agreement with a company with expertise in the field of neurosciences. More particularly, we are willing to find a company involved in the development of therapeutic solutions for the rare disease Spinal Muscular Atrophy (SMA).
Description of the technology
Researchers in the University of Lleida have preclinical evidence for the positive effects of a calpain inhibitor in in vitro and in vivo models for SMA (severe model and mild model for SMA). When treated with this inhibitor, mice survival is substantially prolonged and the clinical course of the disease is improved by means of attenuating body weight loss and motor behavior (righting reflex and tube test). The treatment increases SMN protein level in motor neurons and also prevents neurite degeneration in SMA mutants MNs.
Spinal Muscular Atrophy (SMA) is a genetic neuromuscular disease characterized by muscle atrophy and weakness. The disease generally manifests early in life and is the leading genetic cause of death in infants and toddlers. SMA is caused by defects in the Survival Motor Neuron 1 (SMN1) gene that encodes the SMN protein. The SMN protein is critical to the health and survival of the nerve cells in the spinal cord responsible for muscle contraction (motor neurons).
Disease modifying therapeutic approaches are currently aiming to increase SMN protein levels, using gene therapy to add an exogenous copy of SMN, or protecting motor neurons from degenerating. However, there is no effective treatment for SMA, particularly for the most severe forms (type I and type II).
SMA has generally been believed to affect as many as 10,000 to 25,000 children and adults in the United States, and therefore it is one of the most common rare diseases. One in 6,000 to one in 10,000 children are born with the disease. In Spain, there are around 60 new SMA diagnoses every year.
Spinraza© (Nusinersen, Biogen) is the only drug approved by the FDA and EMA, but there are other candidates in the pipeline. The SMA therapeutics pipeline is segmented into early stage candidates and late stage candidates under development, as Spinraza© long-term effects are still unknown.
