6:00 pm Dinner Short Course*

6:30-9:30 SC1: Examining the Safety and Toxicity of Nucleic Acid Therapeutics

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

8:00 am Breakfast Breakout Roundtable Discussions

CRITICAL FEEDBACK ON REGULATORY SUBMISSIONS

9:15 Chairperson’s Opening Remarks

Paul Manley, President & Principal Consultant, Orvieto Consulting


9:20 FDA PERSPECTIVE: CMC Regulatory Considerations for Oligonucleotide Therapeutics

Mohan Sapru, PhD, CMC Lead and Application Technical Lead, Office of New Drug Products, Member, Emerging Technology Team (ETT), Office of Pharmaceutical Quality, CDER/FDA

Oligonucleotide therapeutics involves the use of a still-evolving class of very promising therapeutic agents that have the potential to target any protein including those considered “undruggable” using small molecule or protein therapeutics. However, the use of therapeutic oligonucleotides often poses unique scientific and regulatory challenges mainly because: a) they are extremely diverse in terms of their structural characteristics and pharmacological properties, b) they have features of both small molecule drugs and biologics, and c) the mechanism(s) of their toxicological and safety liabilities is not well understood. Furthermore, there are currently no ICH or FDA regulatory guidelines that specifically address quality expectations for therapeutic oligonucleotides. This presentation will aim to discuss salient CMC regulatory considerations for synthetic therapeutic oligonucleotides with emphasis on a broader perspective of designing control strategies for lifecycle management of oligonucleotide-based drug products.

9:50 Regulatory CMC Experience for OnpattroTM (patisiran), a First-in-Class siRNA Therapeutic

Samantha Gao-Sheridan, PhD, Senior Director, Regulatory Affairs CMC, 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.
