Compound class: Antibody
Comment: Apitegromab (SRK-015) is an anti-myoststin (GDF8) monoclonal antibody that is being developed by Scholar Rock . Antagonism of myostatin's inhibitory effect on skeletal muscle mass is being predicted to combat muscle atrophy that is observed in patients with the neuromuscular degenerative disease spinal muscular atrophy (SMA). SRK-015 binds to promyostatin and latent myostatin in both serum and muscle . In a mouse SMA model, a precursor of SRK-015 (muSRK-015P) increased muscle mass and function, which is indicative of therapeutic potential.
The primary defect in SMA occurs in defective production of survival motor neuron (SMN) protein and there are already approved drugs that are designed to promote production of functional SMN. Each drug uses a different mechanism to achieve this effect: Roche's Evrysdi® (risdiplam) is a SNM-2 splicing modifier, Biogen's Spinraza® (nusinersen) is an antisense oligonucleotide and Novartis have their gene therapy Zolgensma® (onasemnogene abeparvovec). Myostatin inhibition is likely to be considered as an adjunct to these existing therapies.
Peptide sequences submitted for the INN match patened sequences that are claimed in Scholar Rock's patent WO2017120523A4, and refer to a humanized IgG4 monoclonal referred to as Ab2 in the patent .
Ligand Activity Visualisation Charts
These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.✖
