CARLSBAD, Calif. - Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), the leader in antisense therapeutics, announced that Ionis and its collaborators will present data from its neurological disease programs at the Society for Neuroscience (SfN) Annual Meeting in San Diego, California from November 3-7, 2018.

Data and topics covered in a platform presentation and 11 posters will include:

  • The therapeutic potential of antisense therapies targeting glial cells in rare and fatal demyelinating disorders, including Alexander disease, multiple sclerosis, traumatic injuries and stroke.
  • The demonstration of sustained reductions in ataxin-3 (ATXN3) protein and complete rescue of motor and behavioral impairments using ATXN3-targeted antisense oligonucleotides in spinocerebellar ataxia type 3 (SCA3) mouse models, supporting continued development.
  • The observed reductions and reversal of disease markers in animal models of Alzheimer's disease pathogenesis in Down syndrome treated with β amyloid antisense therapy.
  • The in vivo screening platform for amyotrophic lateral sclerosis (ALS) targets used to validate the preclinical efficacy of IONIS-SOD1Rx (also known as BIIB067).
  • Investigations into mechanisms to enhance antisense oligonucleotides crossing the blood brain barrier.
  • Ionis Pharmaceuticals (PRNewsfoto/Ionis Pharmaceuticals, Inc.)

About Antisense Technology
The instructions for making a protein are transcribed from a gene, or DNA, into a different genetic molecule called messenger RNA (mRNA). This process starts with the partial uncoiling of the two complementary strands of the DNA. One strand acts as a template and information stored in the DNA template strand is copied into a complementary RNA. Messenger RNA, or mRNA, are mature, fully processed RNA that code for proteins. Ribosomes, the cell's factories for manufacturing proteins, translate mRNA into proteins.

The mRNA sequence that carries the information for protein production is called the 'sense' strand. The complementary nucleotide chain that binds specifically to the mRNA sense strand is referred to as the "antisense" strand. Information contained in mRNA can be used to design chemical structures called antisense oligonucleotides (ASOs) or antisense drugs, which resemble DNA and RNA and are the complement of RNA.

Antisense drugs bind with high selectivity to the mRNA they are designed to target and interrupt the cell's protein production process by preventing the mRNA instructions from reaching the ribosome, thus inhibiting the production of the protein. Antisense drugs can also be designed to increase protein production for diseases caused by the lack of a particular protein or can modify the processing, or splicing, of the mRNA, which can alter the composition of the protein.

About Ionis Pharmaceuticals, Inc.
As the leader in RNA-targeted drug discovery and development, Ionis has created an efficient, broadly applicable, proprietary antisense technology platform with the potential to treat diseases where no other therapeutic approaches have proven effective. Our drug discovery platform has served as a springboard for actionable promise and realized hope for patients with unmet needs – such as children and adults with spinal muscular atrophy (SMA). We created SPINRAZA® (nusinersen)* and are proud to have brought new hope to the SMA community by developing the first and only approved treatment for this disease.

Our sights are set on all the patients we have yet to reach with a pipeline of more than 40 drugs with the potential to treat patients with cardiovascular disease, rare diseases, neurological diseases, infectious diseases and cancer. We created TEGSEDI™ (inotersen) the world's first RNA-targeted therapeutic approved for the treatment of polyneuropathy of hereditary transthyretin (TTR) amyloidosis (ATTR) in adult patients that our affiliate Akcea Therapeutics is commercializing. Together with Akcea, we are also bringing new medicines to patients with cardiometabolic lipid disorders.

*Spinraza is marketed by Biogen.
