SteerOn offers Integrated Discovery Chemistry Services helping clients to fast tract their IND submission
Toxicology provides vital information used by regulatory agencies and decision-makers to implement programs and policies aimed at limiting our exposure to harmful substances. This helps prevent diseases and negative health outcomes.
Pharmacovigilance involves detecting, assessing, understanding, and preventing adverse effects or other issues related to medicines and vaccines. Before authorization, all medications and vaccines undergo rigorous safety and efficacy testing in clinical trials.
A CMC consultant can guide you through each step of your project, including writing requests for proposals (RFP) and contacting qualified CDMOs (Contractors).
