Sample text

An assessment of efficacy is made, and those treatments that seem effective enough proceed to Stage 2, though not all will past the first stage (another form of ‘pick the winner’). 3 Choosing outcome measures Phase II studies should be conducted in a relatively short space of time, and the main endpoint should be compatible with this, as well as being clinically relevant. Therefore, several surrogate endpoints can be used (page 17). Observed changes in a validated surrogate endpoint may indicate an effect on a true endpoint.

4 Summary points r Phase I studies are small and aim to provide a first assessment of safety in human subjects r There are simple designs for determining the dose of a new drug that has an acceptable number of serious side-effects r Trials of new, safer therapies may need to have different biological endpoints as well as toxicity r Reports of phase I studies should provide clear information on the pharmacological properties of a new drug, including plasma concentration curves over time, and details of adverse events.

If a different risk were assumed, such as 1 in 4, the decision rules would need to change. While this design is simple, there are limitations. If the starting dose is too low, there may be no DLTs until after several doses have been administered. Therefore several subjects would have been treated without providing much information about the MTD of the new drug, and the trial would take longer. e. the study stops too early. If the drug is not too toxic, the design can be adapted to reduce the probability of stopping early.
