Accelerating the speed of innovative anti-tumor drugs to first-in-human trials incorporating key de-risk strategies.

Pharmaceutical companies have recently focused on accelerating the timeline for initiating first-in-human (FIH) trials to allow quick assessment of biologic drugs. For example, a stable cell pool can be used to produce materials for the toxicology (Tox) study, reducing time to the clinic by 4-5 months. During the coronavirus disease 2019 (COVID-19) pandemic, the anti-COVID drugs timeline from DNA transfection to the clinical stage was decreased to 6 months using a stable pool to generate a clinical drug substrate (DS) with limited stability, virus clearance, and Tox study package.

A functional motif QLYxxYP is essential for osteopontin induced T lymphocyte activation and migration.

Osteopontin (OPN) plays an important role in regulating lymphocyte adhesion and cytokine production associated with inflammatory processes and autoimmune diseases. Here we developed and characterized a monoclonal antibody F8E11 specific for human OPN (hOPN). F8E11 could inhibit OPN-induced lymphocyte activation and migration.
