6:00 pm Dinner Short Course*
6:30-9:30 SC1: Examining the Safety and Toxicity of Nucleic Acid Therapeutics - Detailed Agenda
Nucleic acid drugs continue to deliver on their promise to become a third therapeutic modality, besides small molecules and biologics. Several antisense oligonucleotide drugs have been on the market for some time, while the first RNAi approval was granted
last year (2018). In addition, numerous mRNA and CRISPR therapeutic programs have entered clinical stages. Despite the common “nucleic acid” component, the mechanisms of action and of non-specific effects differ for each of these drug
types.
Topics to be discussed include:
- Different types of nucleic acid-based drugs
- Mechanisms of actions and non-specific effects
- Current approaches to address non-specific and potentially toxic effects
Aimed at both novice and advanced nucleic drug developers, the course will:
- Introduce and explain the differences between various types of nucleic acids drugs
- Summarize our current understanding of the origins of non-specific and potentially toxic effects
- Provide certain directions as to how to minimize the potential toxic effects of nucleic acids drugs

8:15 RNA Targeting with Antisense Oligonucleotides: Present and Future
Richard S. Geary, PhD, Senior Vice President, Development, Ionis Pharmaceuticals
The number and chemical breadth of antisense oligonucleotide (ASO) medicines has rapidly grown in both clinical development and in market approvals. As the technology matures and innovations in delivery and increased safety margins are discovered, the
ASOs currently in development are well balanced between rare and broad diseases. Some of the unique aspects associated with single strand ASO chemistry, distribution, cell uptake, clinical pharmacology and safety will be discussed as applied to clinical
development examples and overall research progress.

Lubo Nechev, PhD, Vice President Process and Analytical Sciences, Alnylam Pharmaceuticals
ONPATTRO (patisiran), the first RNA interference (RNAi) therapeutic approved in the United States and the European Union is targeting transthyretin (TTR) for the treatment of hereditary ATTR amyloidosis. Patisiran comprises a double stranded RNA API
in a lipid nanoparticle formulation for intravenous administration. The presentation will discuss the development of the CMC strategy for patisiran from early stage to approval.
11:20 Stage 3 Continued Process Verification of Commercial Oligonucleotide Synthesis: Monitoring Strategy and Process Observations
Francis Ring, Assistant Director, Manufacturing & Operations, Ionis Pharmaceuticals
As more Oligonucleotide Therapies are approved, it is important to develop appropriate Continued Process Verification procedures, both to satisfy regulatory requirements and to inform future process development. Since 2010, across three compounds,
Ionis has been performing validated solid-phase syntheses. The process data collection, analysis, and reporting strategy will be described, along with their evolution over time. Additionally, notable process trends and observations will be presented.
11:50 Enabling Rapid Start-Up with End-to-End Antisense Oligonucleotide Capability and Streamlined Business Processes
Sheron Branham, Associate Director, ASO Process Engineering and Manufacturing, Biogen
Biogen is the first innovator to internalize end-to-end ASO manufacturing capability while others have chosen to outsource. By vertically integrating their ASO supply chain, Biogen has been able to significantly reduce turnaround time and supply
risk. The presentation will highlight how the facility and the business processes were designed to maximize flexibility and prepare for potential rapid growth in the future.
12:20 Enjoy Lunch on Your Own
2:00 siRNA Case Study: Development and Implementation of Late Stage CMC Strategies
Vidhya Gopalakrishnan, PhD, Senior Vice President, Pharmaceutical Development, Quark Pharmaceuticals
Assay testing or weight-based determination of API content is an important aspect of release testing. Determining the assay of double-stranded oligonucleotide therapeutics is complicated. Because the duplex is formed by annealing two single strands,
there will likely be closely related duplex variants arising from annealing of the impurities of the single strands thus making it difficult to discriminate variants from the parent duplex. This presentation will discuss findings from a comparative
assessment of specific denaturing and non-denaturing chromatographic methods for assay measurement of a siRNA duplex and implications for release testing.
2:30 Combining siRNA and Peptides for Improved Delivery – CMC Aspects
Marc Lemaitre, PhD, COO, Sirnaomics and ML_Consult
Branched peptides containing histidines and lysines (HK) have been shown to be effective carriers for DNA and siRNA. We will discuss the specific aspects of CMC for the development of such a product.

drug modalities are offering a better alternative. This course will bring together experts who will share their perspectives on the opportunities and challenges underlying the generation of novel, more targeted and effective oligonucleotide-based
therapies for cancer immunotherapy. Some topics that will be discussed include:
- Modulating the tumor microenvironment using novel approaches and drug modalities
- Emerging immuno-oncology targets (TLRs, STING, RIG-1 and more) for intervention using oligos
- Preclinical and clinical evaluation of new immunomodulatory pathways and nucleic acids
- Synthesis and delivery of oligonucleotides (siRNA, antisense, aptamers and others) for cancer immunotherapy

9:50 FEATURED PRESENTATION: Regulatory CMC Experience for OnpattroTM (patisiran), a First-in-Class siRNA Therapeutic
Saraswathy (Sara) Nochur, PhD, Chief Regulatory Officer, Alnylam Pharmaceuticals
OnpattroTM (patisiran) became the first FDA/EMA-approved treatment of polyneuropathy caused by hereditary transthyretin-mediated amyloidosis (hATTR), and the first regulatory approval of a new class of drugs called small interfering ribonucleic
acid (siRNA). CMC development of OnpattroTM involved extensive innovation, challenges due to complexity of the product (consisting of double-stranded siRNA and lipid components including novel excipients), and well-planned interactions
with regulatory agencies. Regulatory CMC experience on Onpattro development and registration will be provided.

11:35 Strategies for Identity Testing of Oligonucleotide Therapeutics
Hong Jiang, Scientist II, Analytical Development, Biogen
Due to their polymeric nature and high molecular weight, establishing identity of oligonucleotide therapeutics is significantly more challenging compared to synthetic small molecules. The commonly accepted identity tests for small molecules,
such as IR spectrum and retention time matching with a reference standard, are generally insufficient for identity confirmation of an oligonucleotide. In this presentation I will discuss various risk factors during the manufacturing process
that can potentially lead to an oligonucleotide of an incorrect structure, along with currently available analytical methods that can detect certain structural changes and confirm the identity. A risk-based framework for the selection
of identity tests and how it can be integrated into a robust control strategy will be proposed.
12:05 pm Regulatory Agency Questions and Learnings from Recent Commercial Submissions
Jennifer Franklin, Director, CMC Regulatory Affairs, Ionis Pharmaceuticals
Recent CMC questions received from global regulatory agencies for an antisense oligonucleotide drug will be detailed, along with a discussion of the response strategies that led to their successful resolution, and ultimately, to drug approval.
Regulatory challenges and learnings from the review and approval process in the US, EU, and Canada will also be examined.

5:30-8:30 SC3: CRISPR-Based Gene Editing for Targeted Therapies - Detailed Agenda
While the challenges and risks associated with oligonucleotide therapies still remain, there is a new and better understanding of how genes can be effectively manipulated and delivered. With the rise of gene editing tools and enhanced
knowledge of targeted delivery, these therapeutic modalities are once again being embraced with renewed hope and enthusiasm. This course helps you understand how gene editing – particularly the one enabled by the CRISPR (Clustered
Regularly Interspaced Short Palindromic Repeats)/Cas9 system – works, and how it can be used to help develop targeted therapies with good efficacy and delivery.
