First-in-human to proof-of-concept clinical studies
Quotient Sciences' first-in-human clinical studies are backed by extensive clinical and medical expertise, along with comprehensive formukation, manufacturing, and pharmacy capabilities.
Our fully integrated programs span all types of drug modalities and include single and multiple ascending dose (SAD/MAD) studies in healthy volunteers, special populations, and patient cohorts.
At our clinics in the US and UK, we have the ability to recruit patients across various therapeutic areas such as inflammation, metabolic diseases, and CNS disorders for initial proof-of-concept.
Exploratory and regulatory driven studies for registration and product labelling
Draw on our extensive clinical and medical expertise for your Phase 1 clinical pharmacology studies and product labeling purposes. Our capabilities include a range of study types, such as TQT, drug-drug interaction (DDI), food effect, bioavailability/bioequivalence (BA/BE), and human ADME studies.
Phase 1 clinical pharmacology studies can be executed standalone or bundled together for cost and time efficiencies. Additionally, we have the capacity to swiftly recruit large panels of healthy volunteers and special populations.
Purpose-built Phase I units, dedicated to the success and safety of your study.
