nQuery Summer 2019 Release | 41 new sample size tables

From fixed to flexible trial designs, the nQuery Summer 2019 release (ver 8.4) sees the continued strengthening of nQuery to help Biostatisticians and clinical researchers save costs, reduce risk and help clinical trials be successful.

We are delighted to let you know the nQuery Summer 2019 update is now available. For full info on the 41 new sample size tables new tables -  including survival adaptive - go to statsols.com/whats-new. For a quick summary, then please see below.

With increasing costs and high failure rates in drug development, adaptive trials offer one mechanism to alleviate these problems and make clinical trials better reflect the statistical and practical needs of trial sponsors. These issues have also spurred an increasing openness towards innovative clinical trial designs in regulatory agencies around the world.
