First Steps for a New Validation Strategy for a Family of Oligonucleotide Sequences
Prosensa is in a unique position developing six oligonucleotide sequences for sub-populations of Duchenne Muscular Dystrophy patients, restoring the dystrophin production in muscle cells. The processing for the sequences is highly similar. A new validation strategy, creating a shared design space, will enable Prosensa to reduce validation and accelerate development of new sequences for other sub-groups of DMD patients.

When to Choose Recombinant vs. Synthetic Production of Peptides: The Complexities of a "Simple" Decision
As the complexity of peptides grows, the age-old question of synthetic vs. recombinant production gets more difficult to answer. In this forum, a panel of experts from industry will discuss what factors need to be part of the decision. Some of the questions we hope to probe in the discussion include:
  1. The role of manufacturing capacity. When is a peptide "too big" for synthetic production?
  2. Considerations from a regulatory perspective - NDA vs. BLA?
  3. The route for introduction of bio-similar peptides.
  4. The need for structural specificity to hit the receptor; can it be managed by production method?

Solving Aggregation Aggravation: From Peptide T to Monomeric DAPTA, A Peptide HIV Antiviral that Reduces Cellular Infectious Viral Load (Reservoirs)
After several clinical trials and two decades, chemically pure formulations of the viral envelope- derived octapeptide (which appeared no more viscous than water) were discovered to have lost all bioactivity by gradual aggregation. Detecting aggregation of the octapeptide by bioassay and physical methods permitted the development of a potent, non-aggregating intranasal formulation still fully active two years out.

From R&D to Revolutionary Peptide ProductionSponsored by
Lonza developed and patented an evolution of conventional liquid phase peptide synthesis (LPPS) that combines the best characteristics of LPPS with the key benefits of solid phase peptide synthesis (SPPS). Lonza kept standard reagents and protected amino acids involved in SPPS for its new approach, in addition no special C-terminal anchor where found needed. The higher purity of crude peptide product created by Lonza lessens the purification load and helps reduce the development time normally associated with LPPS, while generating a greater yield of higher-purity peptides.

Preclinical Evaluation of Immunomodulatory Effects of Oligonucleotides and Formulations: Challenges and Strategies
Oligonucleotide therapeutics fall into two categories: Those that take advantage of immunomodulatory effects and those that try to avoid them. Preclinical models of immunomodulatory effects, either beneficial or toxic, are problematic at best. This panel will discuss the practical value of preclinical models for oligonucleotide and formulation lead development, the challenges of simple versus complex formulations of oligonucleotides, the pros and cons of in vivo versus ex vivo models, the regulatory requirements for immunotoxicity testing, and the impact on chronic versus acute use and routes of administration.
Key discussion points:
  • When is an immunomodulatory response a toxicity or a beneficial effect?
  • How do we distinguish between nucleic acid and formulation component immunotoxicity?
  • How much value is there in screening nucleic acid and formulation components separately for immunotoxicity?
  • What are meaningful preclinical screens for the immunomodulatory interactions between oligonucleotide API and formulation components?
  • Will chemical modifications of oligonucleotides alone solve immunotoxicity problems?
  • Are preclinical models of immunomodulatory effects of any real value, or will each new Phase 1 be a high-risk gamble?
  • Have any consistent cytokine release signals emerged in preclinical models that are of any predictive value?
  • Given the struggle to identify relevant preclinical species indicative of immunotoxicity, are non-human primates the best surrogate to date?
  • Are human cells or whole blood the answer to accurately evaluate positive and negative immunomodulatory effects?

Alternative Delivery Platforms for Oligonucleotide and Peptide Therapeutics
Peptides and oligos are not normally amenable to oral administration due to hydrolysis by gut enzymes and poor absorption from the GI tract. As a result, administration by injection is often the default delivery route and can become a source of noncompliance. The Strategy Discussion Forum will address the advantages/disadvantages of alternative delivery platforms and their acceptability to physicians, patients and health providers. Additionally, the commercial suitability and viability of alternative delivery technologies for different types of oligo and peptide drug substances and dosages will be discussed. The forum will also examine the pros and cons of introducing alternative delivery formats during different stages of the drug development process.

Conjugation: From a One-Off Approach to a Platform Technology - Pros and Cons
The benefits of conjugating oligonucleotides or peptides (PEGylation, mAb conjgate, etc.) will be briefly reviewed via examples. The panel will then discuss the pros and cons of a platform strategy for conjugation. For established modalities, the need to screen conjugate components in a systematic fashion and ultimately to generate candidates to feed the pipeline has led to a push in the industry for a platform approach to conjugation. Platformization can help speed development by building on lessons learned and compress overall timelines. At the same time, a too rigid strategy can hinder innovation or delay adoption of new technologies. Panelists will discuss how companies bring the necessary flexibility to their conjugates platform strategy or opt for a one-off approach.
