Why In Vivo Biological Testing Matters

While in vitro assays prove that liposomes are safe and highly effective at the cellular level, in vivo biological testing provides the ultimate scientific validation by tracking their performance within a complex, living organism. Through in vivo biological evaluation, three definitive milestones are determined: systemic bioavailability & ADME profiling, systemic safety & tolerability and real-world efficacy. By demonstrating the formulation’s behaviour in a complex biological system while delivering health benefits, in vivo evaluation serves as the essential, data-driven bridge required to confidently advance a product into human clinical trials (CT). It is therefore a prerequisite testing and stepping stone towards clinical trials.
