NOVARTIS AG CHF0.50(REGD) Novartis Announces Avxs-101 Intrathecal Study Update

TIDMNOVN
-- FDA placed a partial hold on AVXS-101 intrathecal clinical trials for SMA
patients based on findings in a small pre-clinical animal study
-- Adverse events that might be expected from the pre-clinical findings have
not been seen in a thorough review of human safety data from all
available sources to date
-- Zolgensma(R) (onasemnogene abeparvovec-xioi) also known as AVXS-101
intravenous administration is not impacted and remains available in the
US
-- Novartis is working with FDA to determine next steps to release partial
hold and resume dosing in the AVXS-101 intrathecal trials
Basel, October 30, 2019 -- Novartis today announced the United States
Food & Drug Administration (FDA) placed a partial hold on clinical
trials for intrathecal administration of AVXS-101. The announcement
follows an AveXis 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
(DRG) mononuclear cell inflammation, sometimes accompanied by neuronal
cell body degeneration or loss. This partial hold by the FDA does not
impact marketed Zolgensma(R) or AVXS-101 intravenous (IV) clinical
trials.
AveXis is studying AVXS-101 intrathecal administration in patients with
spinal muscular atrophy (SMA) Type 2. The partial hold impacts
enrollment in the high dose cohort of the STRONG trial, an ongoing,
open-label, dose-comparison, multi-center trial designed to evaluate the
efficacy, safety and tolerability of one-time intrathecal administration
of AVXS-101. The low and mid dose cohort enrollment has previously been
completed and interim results have been presented.
The clinical significance of the DRG inflammation observed in this
pre-clinical animal study is not known and was not seen in prior animal
studies with AVXS-101. DRG inflammation can be associated with sensory
effects. Of note, we have completed a thorough review of human safety
data from all available sources to date and no adverse effects related
to sensory changes have been seen in AVXS-101 intrathecal or Zolgensma.
We are working with health authorities to confirm further guidance to
clinical investigators.
We will continue to closely monitor for any reports of related safety
events in patients. We remain confident that the overall benefit-risk
profile for patients on treatment is favorable and we continue to
advance our AVXS-101 intravenous clinical studies. We will work
diligently with FDA to identify any additional actions necessary to
resume dosing in the AVXS-101 intrathecal clinical trials.
AveXis and Novartis remain committed to researching and developing gene
therapies for SMA, a rare and devastating genetic disease.
About AVXS-101 Intrathecal Administration
Investigational IT administration of AVXS-101 is currently being
evaluated in patients with SMA Type 2 in a Phase 1/2 clinical trial.
Zolgensma in the United States
Indication
Zolgensma (onasemnogene abeparvovec-xioi) is an adeno-associated virus
vector-based gene therapy indicated for the treatment of pediatric
patient less than 2 years of age with spinal muscular atrophy (SMA) with
bi-allelic mutations in the survival motor neuron 1 (SMN1) gene.
Limitation of Use
The safety and effectiveness of repeat administration of Zolgensma have
not been evaluated.
The use of Zolgensma in patients with advanced SMA (e.g., complete
paralysis of limbs, permanent ventilator-dependence) has not been
evaluated.
Important Safety Information
Acute Serious Liver Injury
Acute serious liver injury and elevated aminotransferases can occur with
Zolgensma. Patients with pre-existing liver impairment may be at higher
risk. Prior to infusion, assess liver function of all patients by
clinical examination and laboratory testing (e.g., hepatic
aminotransferases [aspartate aminotransferase and alanine
aminotransferase], total bilirubin and prothrombin time). Administer
systemic corticosteroid to all patients before and after Zolgensma
infusion. Continue to monitor liver function for at least 3 months after
infusion.
Thrombocytopenia
Transient decreases in platelet counts, some of which met the criteria
for thrombocytopenia, were observed at different time points after
Zolgensma infusion. Monitor platelet counts before Zolgensma infusion
and on a regular basis afterwards.
Elevated Troponin-I
Transient increases in cardiac troponin-I levels (up to 0.176 mcg/L)
were observed following Zolgensma infusion in clinical trials. The
clinical importance of these findings is not known. However, cardiac
toxicity was observed in animal studies. Monitor troponin-I before
Zolgensma infusion and on a regular basis for at least 3 months
afterwards.
Adverse Reactions
The most commonly observed adverse reactions (incidence >=5%) were
elevated aminotransferases and vomiting.

About Spinal Muscular Atrophy (SMA)
SMA is a severe neuromuscular disease characterized by the loss of motor
neurons leading to progressive muscle weakness and paralysis. SMA is
caused by a genetic defect in the SMN1 gene that codes SMN, a protein
necessary for survival of motor neurons.[3],[4] The incidence of SMA is
approximately 1 in 10,000 live births and it is the leading genetic
cause of infant mortality.[1],[4] The most severe form of SMA is Type 1,
a lethal genetic disorder characterized by rapid motor neuron loss and
associated muscle deterioration, resulting in mortality or the need for
permanent ventilation support by 24 months of age for more than 90
percent of patients if left untreated.[5] More than 30% of patients with
SMA Type 2 will die by age 25.2
