Novartis to Start AVXS-101 IT Confirmatory Study
Novartis Gene Therapies says that based on an FDA recommendation it will undertake a pivotal confirmatory study to supplement the existing STRONG data on the intrathecal formulation of AVXS-101 in older patients with spinal muscular atrophy. The company says the agency acknowledged the potential of AVXS-101 IT in the patient population.
Guidance from FDA provided clarity on the path to registration for AVXS-101 IT, Novartis says, and trial design and other details are being evaluated.
The agency had placed a 10/2019 partial clinical hold on clinical trials for intrathecal administration of AVXS-101 following an AveXis (now Novartis Gene Therapies) communication to health authorities and clinical trial investigators based on findings from a small AveXis-initiated pre-clinical study in which animal findings showed dorsal root ganglia mononuclear cell inflammation, sometimes accompanied by neuronal cell body degeneration or loss.
The clinical hold did not affect the intravenous administration of Zolgensma (onasemnogene abeparvovec-xioi), also known as AVXS-101 intravenous administration.
