Molecular Feedback Loop May Explain Motor Neuron Damage

The RNA-binding protein Mid1 increases levels of the mutated androgen receptor (AR) that drives nerve cell degeneration in spinal and bulbar muscular atrophy (SBMA), a new study shows. Since Mid1 is expressed mainly in lower motor neurons, the nerve cells mainly affected in SBMA, the study’s researchers proposed that…

Spinraza Improves, Stabilizes SMA-related Motor Function: Study

Spinraza (nusinersen) treatment was generally well tolerated and led to improved or stabilized motor function for nearly 300 children with spinal muscular atrophy (SMA) in Poland, a new study reports. The study, “Safety, tolerability, and efficacy of a widely available nusinersen program for Polish children with Spinal Muscular…

Manitoba Newborn Screening Program Expands to Include SMA

The newborn screening program at Cadham Provincial Laboratory in Manitoba, Canada, is expanding to include spinal muscular atrophy (SMA), according to an announcement from Audrey Gordon, the province’s health minister. “Early diagnosis is the key to improving outcomes for babies born with metabolic, endocrine or genetic disorders such as…

Evrysdi Gets FDA Approval for SMA Babies Under 2 Months Old

The U.S. Food and Drug Administration (FDA) has extended its approval of Evrysdi (risdiplam) to treat babies with spinal muscular atrophy (SMA) who are younger than 2 months old. Evrysdi, an oral therapy that works by increasing the levels of the survival motor neuron (SMN) protein that is missing in…

CADTH Panel Recommends Against Reimbursing Spinraza for Adults

A committee of the Canadian Agency for Drugs and Technologies in Health (CADTH) has issued a draft recommendation advising Spinraza (nusinersen) should not be reimbursed for the treatment of adults with spinal muscular atrophy (SMA).  CADTH is an independent, nonprofit organization that provides evidence-based advice to…
