Unveiling the Power of Oligonucleotide Therapeutics

Oligonucleotide therapeutics, a mouthful to pronounce but an exciting field nonetheless, holds immense potential for revolutionizing modern medicine. Ionis Pharmaceuticals, the trailblazing leader in this domain, has harnessed the power of RNA-targeted therapies to develop groundbreaking treatments. 

At the forefront of their innovation is the concept of antisense technology, which involves manipulating the building blocks of genetic material to target and modulate disease-causing genes. By leveraging the natural processes within our cells, Ionis is paving the way for innovative approaches to previously untreatable diseases. With their pioneering research, Ionis is bringing the future of medicine into the present.

One of the key breakthroughs in oligonucleotide therapeutics achieved by Ionis is their ability to design molecules called antisense oligonucleotides (ASOs). These ASOs are custom-built to bind to specific RNA molecules, regulating their function and altering disease processes at the genetic level. 

The versatility of ASOs allows for the development of targeted therapies for a wide range of conditions, from genetic disorders to neurological diseases and even certain types of cancer. Ionis Pharmaceuticals has truly unlocked the potential of oligonucleotide therapeutics to address unmet medical needs.

A Well-Deserved Award: Recognizing Breakthrough Research

In the ever-evolving world of scientific research, recognition plays a vital role in driving progress forward. Ionis Pharmaceuticals’ dedication to pushing the boundaries of oligonucleotide therapeutics has not gone unnoticed. 

In 2019, the company received the prestigious OTS Paper of the Year Award for their publication titled “Chemical Modification of PS-ASO therapeutics reduces cellular protein-binding and Improves the therapeutic index” in Nature Biotechnology. This highly esteemed accolade recognizes the most impactful paper in the field of oligonucleotide therapeutics, shedding light on the immense value of Ionis research.

The awarded publication showcases Ionis’ commitment to basic research and highlights the significance of chemical modifications in enhancing the efficacy and safety of their antisense oligonucleotide therapies. 

By reducing cellular protein binding, Ionis scientists have improved the therapeutic index, which is a measure of the balance between efficacy and toxicity. This breakthrough not only demonstrates the ingenuity of Ionis researchers but also opens new horizons for the development of even better medicines in the field of oligonucleotide therapeutics. 

Ionis CEO and founder, Stanley Crooke, M.D., Ph.D., played a pivotal role as one of the contributing authors of the award-winning publication. This recognition not only reflects Ionis’ commitment to scientific excellence but also reaffirms its position as a pioneer in the field.

The Rising Star: Holly Kordasiewicz and the Young Investigator Award

Every field needs fresh faces and innovative minds to drive progress forward. The Oligonucleotide Therapeutics Society (OTS) recognizes the outstanding achievements and contributions of professional scientists through the Mary Ann Liebert, Inc. publishers Young Investigator Award. 

In 2019, this prestigious honor went to Holly Kordasiewicz, Ph.D., Ionis’ executive director of neurological disease drug discovery. Dr. Kordasiewicz’s dedication to unraveling the mysteries of neurodegenerative diseases has earned her this well-deserved recognition.

Neurodegenerative diseases, such as spinal muscular atrophy, Huntington’s disease, and amyotrophic lateral sclerosis, pose immense challenges for patients and researchers alike. Dr. Kordasiewicz’s transformative antisense medicines offer hope to countless individuals affected by these devastating conditions. 

Her groundbreaking research and innovative approach have shed light on potential therapeutic strategies to combat these diseases. By targeting the underlying genetic factors contributing to neurodegeneration, Dr. Kordasiewicz and her team at Ionis are pioneering new avenues for treatment.

Ionis Presentations: Unveiling the Future of Oligonucleotide Therapeutics

When it comes to showcasing its groundbreaking research, Ionis Pharmaceuticals doesn’t hold back. The 15th Annual Meeting of the Oligonucleotide Therapeutics Society in Munich, Germany, provided an ideal platform for Ionis scientists to present their latest advancements in antisense technology. These presentations covered a range of topics, each shedding light on the potential of oligonucleotide therapeutics to transform the landscape of medical treatments.

On October 2019, Ionis scientists delved into the fascinating realm of RNA processing. Their presentation titled “Cleavage of pre-mRNA in the Nucleus by RNase H1-dependent Antisense Oligonucleotides Causes RNA Polymerase II Transcription Termination” highlighted the mechanisms by which antisense oligonucleotides can modulate gene expression at the transcriptional level. Understanding these intricate processes is crucial for harnessing the full potential of oligonucleotide therapeutics.

Another captivating presentation titled “Development and Characterization of AZD8701, a High-Affinity Antisense Oligonucleotide Targeting FOXP3 to Relieve Immunosuppression in Cancer” took place that year. The Ionis team showcased their efforts to tackle the challenges posed by immunosuppression in cancer. 

By specifically targeting the FOXP3 gene, which plays a crucial role in immune regulation, Ionis aims to develop therapies that enhance the anti-cancer immune response. This novel approach holds immense promise for improving cancer treatment outcomes.

Moreover, the conference provided an opportunity to honor the recipients of prestigious awards. Dr. Kordasiewicz, the winner of the Young Investigator Award, delivered a captivating talk on her groundbreaking research in the treatment of neurodegenerative diseases. The recognition bestowed upon her by the OTS serves as a testament to her dedication and the potential of oligonucleotide therapeutics in addressing unmet medical needs.

Beyond the Stage: Ionis’ Poster Presentations

While oral presentations often steal the spotlight at scientific conferences, poster presentations are the unsung heroes that offer a more intimate glimpse into ongoing research. 

Ionis Pharmaceuticals made sure to captivate the audience with its visually engaging and information-packed posters. These displays covered a range of topics, each shedding light on various aspects of oligonucleotide therapeutics and Ionis’ cutting-edge research. One of the posters, titled “Invalidation of GSK3B in the Pancreatic Beta Cell as a Therapeutic Target for T2D,” focused on investigating potential therapeutic strategies for type 2 diabetes (T2D). 

By exploring the role of GSK3B, a protein kinase implicated in diabetes, Ionis scientists aim to identify novel approaches to modulating pancreatic beta cell function. This research represents a step forward in the quest to develop more effective treatments for T2D, a prevalent and challenging disease.

Another poster presentation titled “Improved Safety & Tolerability Profile with Ligand Directed Delivery of Antisense Oligonucleotides in Humans: An Integrated Comparison of Parent 2′-OMethoxyethyl Chimeric ASOs to the GalNAc3-Conjugates” tackled the critical issue of safety and tolerability in oligonucleotide therapeutics. 

Ionis researchers explored ligand-directed delivery systems, such as GalNAc3-conjugates, to improve the safety profiles of antisense oligonucleotides. By optimizing delivery mechanisms, Ionis aims to enhance the therapeutic potential of its RNA-targeted drugs while minimizing side effects.

Additionally, Ionis presented a poster titled “Controlling Chirality of Phosphorothioates in Antisense Oligonucleotides Does Not Enhance Potency or Duration of Effect in the CNS,” which focused on the role of chirality in antisense oligonucleotides’ potency and efficacy in the central nervous system. The research aimed to explore the impact of chirality on therapeutic outcomes, providing valuable insights into the design and optimization of antisense therapies for neurological diseases.

Ionis Pharmaceuticals: A Beacon of Hope for Patients

Beyond the groundbreaking research, awards, and conference presentations, Ionis Pharmaceuticals ultimately strives to bring hope to patients facing unmet medical needs.
