CHIT1 Immune Protein May Be Marker of Response to Spinraza

Levels of an immune protein called CHIT1 change over time in children with spinal muscular atrophy (SMA) who undergo treatment with Spinraza (nusinersen), a small study reports. The findings thus suggest that the protein’s levels — in the cerebrospinal fluid or CSF, the liquid surrounding the brain and…

Evrysdi Found to Help Previously Treated SMA Patients in Trial

Treatment with Evrysdi (risdiplam) increased levels of SMN protein and stabilized motor function in a Phase 2 clinical trial that enrolled spinal muscular atrophy (SMA) patients who had previously been on other therapies, two-year data show. “These important data demonstrate the safety and efficacy of Evrysdi in a…

New Study Suggests Zolgensma Could Work in Adults With SMA

The gene therapy Zolgensma (onasemnogene abeparvovec-xioi), approved in the U.S. for very young children with spinal muscular atrophy (SMA), potentially could work for adults with the rare genetic disorder, a new study suggests. The study reports that few adults with SMA were found to have antibodies against the…

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…
