J&S Preclinical Solutions is a consulting firm specializing in preclinical pharmacology and toxicology. We support biotech companies in designing, monitoring, analyzing and reporting studies from proof of concept through GLP toxicology and regulatory submission. Our expertise spans small molecules and biologics, including monoclonal and bispecific antibodies, ADCs, gene therapies, and CAR T cells, across oncology, CNS, autoimmune, and metabolic diseases.

We take a tailored, hands-on approach to each project, combining strategic guidance, study oversight, and regulatory support. By integrating pharmacology and toxicology early and effectively, we help elevate drug development programs and move them forward faster and with greater confidence.
