** There is a "high unmet need" in spinal muscular atrophy despite approved therapies, which slow neuron loss but do not stop disease progression, says brokerage
** Scholar Rock's therapy, apitegromab, addresses this need by reducing "muscle atrophy by inhibiting myostatin, a protein which causes muscle breakdown, addressing key symptoms of the disease" - BofA
** Brokerage estimates the therapy to record $2 bln in peak sales in 2037
** Even as the U.S. FDA declined to approve the company's filing for the drug due to issues at a third-party manufacturing facility, BofA views this as a "timeline delay rather than as a risk to approval"
** As of last close, shares down 10% YTD
