Strategic Framework for In Vivo Program Execution

A tailored preclinical strategy is fundamental to the successful translation of advanced therapeutics and complex biologics. Applying proven intelligence in preclinical operations accelerates the path to IND by generating reproducible, robust, high-fidelity data from well-characterized in vivo models. This requires a framework that unites scientific objectives and animal welfare as components of a single, rigorous process.

The transition from a highly controlled in vitro environment to a living system introduces significant biological variability. This transition demands expert oversight and study designs that account for this complexity from the outset.

Unification of Ethical Conduct and Scientific Validity

Executing these programs correctly is a scientific and ethical obligation. “We have to do animal research, so let’s do it well. Let’s do it right the first time,” Dr. Naageshwaran advises. “The most important thing is to do it right the first time so you’re not using any more animals than you’re absolutely required to.” This principle minimizes animal use and directly supports the generation of unambiguous data required for regulatory review.

De-Risking Gene Therapies via Long-Term NHP Safety Studies

For next-generation therapies, particularly those involving AAV-delivered gene editing systems, long-term observation in relevant models is necessary to de-risk clinical translation. Preclinical safety evaluations in nonhuman primate (NHP) models provide durability and safety data, establishing a confident profile for novel platforms before they enter human trials (PMID: 33609733).

Core Methodological and Animal Welfare Standards

Our approach to in vivo operations is built on several core tenets:

• Regulatory Adherence: Strict compliance with all international, federal, and local regulations governing animal care, including a firm commitment to the 3Rs: Replacement, Reduction, and Refinement.
• Enhanced Environments: We provide advanced housing conditions that include comprehensive cognitive and social enrichment programs throughout the in-life phase of NHP studies.
• Immunological Relevance: NHP models are selected to ensure the immune system closely mirrors the human immune response.
• Expert Oversight: All studies are managed by a team of board-certified veterinarians, toxicologists, and skilled technical staff dedicated to animal health and data integrity.
