What We Do

Clinical trials to test new drugs are commonly classified into four phases. It may take several years for a drug to pass through all the phases. If the drug successfully passes through the first three phases, it will usually be successfully approved for use in the general population.

Phase I trials are the first-stage of testing in human subjects. Normally a small (20-80) group of healthy volunteers will be selected. This phase is designed to assess the safety and tolerability of a therapy.
Phase II trials are performed on larger groups (20-300) and are designed to assess clinical efficacy of the therapies. This phase can also be broken down to phase IIA and phase IIB.
Phase III trials are controlled trials on large patient groups (300-3000+). This phase is aimed at the efficacy of the new therapy. Some phase III trials are an attempt at “label expansion”. In other words, exploring additional uses beyond the original use for which the drug was designed. This phase is also used to support marketing claims.
Phase IV trials involve the post-launch safety surveillance and ongoing technical support of a drug. This phase is designed to detect any rare or long-term adverse effects over a much larger patient population and timescale.
