TL;DR
Using the estimated effect size difference for the main trial and using a one-sided CI allows us to calculate a sample size for a pilot trial, which will make its results more useful than at present.

When designing a clinical trial an appropriate justification for the sample size should be provided in the protocol, but there are a number of settings when undertaking a pilot trial when there is no prior information to base a sample size on.

BMC Medical Research MethodologyWhat is a pilot or feasibility study? A review of current practice and editorial policy
1,555 Citations2010Mubashir Arain, Michael J. Campbell +2 more
Pilot studies are still poorly reported, with inappropriate emphasis on hypothesis-testing, and authors should be aware of the different requirements of pilot studies, feasibility studies and main studies and report them appropriately.
Journal of Clinical EpidemiologyThe size of a pilot study for a clinical trial should be calculated in relation to considerations of precision and efficiency
1,075 Citations2011Julius Sim, Martyn Lewis
Trialists should calculate the appropriate size of a pilot study, just as they should the size of the main RCT, taking into account the twin needs to demonstrate efficiency in terms of recruitment and to produce precise estimates of treatment effect.
Statistics in MedicineOn the use of a pilot sample for sample size determination
1,042 Citations1995Richard Browne
To compute the sample size needed to achieve the planned power for a t-test, one needs an estimate of the population standard deviation sigma, and Monte Carlo simulations indicate that using a 100(1-gamma) per cent upper one-sided confidence limit on sigma will provide a sample size sufficient to achieve that power.
Statistics in MedicineThe role of internal pilot studies in increasing the efficiency of clinical trials
443 Citations1990Janet Wittes, Erica Brittain
This paper proposes designs, which are term internal pilot studies, that designate a portion of the main trial as a pilot phase, and recommends considering a similar approach for a number of types of endpoints.
