J AND S Preclinical Solutions

About J AND S Preclinical Solutions

Finding solutions to your preclinical challenges

J&S Preclinical Solutions is a team of highly experienced consultants working at the interface of pharmacology, toxicology, and nonclinical drug development. We support biotech and pharmaceutical companies and venture capital partners in assessing and/or advancing their nonclinical programs from target assessment through first-in-human and beyond, including GLP toxicology, bioanalytical support and regulatory submissions.

Our expertise spans both small molecules and biologics, including monoclonal and bispecific antibodies, ADCs and gene therapies - across therapeutic areas including oncology, immunology, CNS, infectious diseases, and metabolic diseases.

Every project is unique, with its own challenges. Rather than applying standard solutions, we build tailored strategies that align science, risk, and regulatory expectations. Our strength lies in combining high-level strategic thinking with hands-on and effective execution, providing clarity, direction and momentum. We work alongside your team—challenging assumptions, asking critical questions, solving critical issues, and building an actionable nonclinical development plan, together.

By integrating pharmacology and toxicology early and intelligently, we are well positioned to de-risk programs, unlock critical decisions, and empowering clients to accelerate projects with confidence.

Curious about how we can help de-risk and accelerate your development program? Whether you are exploring a new asset, refining your nonclinical strategy, or working through a nonclinical development challenge, we invite you to connect with us and start a conversation.
