CADTH: Spinraza Should Not Be Funded for Adults in Canada

In its final decision, the Canadian Agency for Drugs and Technologies in Health (CADTH) recommended against Spinraza (nusinersen) being reimbursed to treat adults with spinal muscular atrophy (SMA).  The decision was met with dismay by the SMA community and Biogen, Spinraza’s manufacturer. “We are absolutely devastated for the…

Zolgensma Label to Include Warning of Acute Liver Failure Deaths

Prescribing information for Zolgensma (onasemnogene abeparvovec-xioi), an approved gene therapy for spinal muscular atrophy (SMA), is being updated following the death of two patients who developed acute liver failure after treatment. Acute liver failure was known to be a potential severe side effect of Zolgensma, highlighted in a…

Support Urged for Parents Informing Their Children of SMA Diagnosis

Children diagnosed with spinal muscular atrophy (SMA) are usually informed about the diagnosis by their parents, who frequently lack support and information about the disease, ultimately leading to poor communication that can be emotionally painful for everyone involved, according to a new study. “Poor communication has a double negative…

Elevated GFAP Levels Linked to More Motor Impairment in SMA

Higher levels of the glial fibrillary acidic protein (GFAP) in the fluid around the brain and spinal cord are associated with poorer motor function among people with spinal muscular atrophy (SMA), a new study reports. These results indicate that cells called astrocytes are more active in advanced SMA, according…

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…
