Posology for Regenerative Therapy.

The science of dosage or posology (from Greek posos, how much, and logos, study) is a branch of pharmacology and therapeutics concerned with treatment dosage and dosage regimen. Establishing optimum dosage underpins every clinical development plan for novel therapeutic candidates. Failure to select the adequate drug dose is a leading culprit for regulatory delays or denial of initial applications for new drugs and, more generally, inadequate dose selection contributes to the high attrition rate of pivotal clinical trials.
