Recent Publication: A Gatekeeping Procedure to Test a Primary and a Secondary Endpoint in a Group Sequential Design with Multiple Interim Looks

Posted by Cytel

Feb 15, 2018 10:35:00 AM


A recent publication in Biometrics ‘A Gatekeeping Procedure to Test a Primary and a Secondary Endpoint in a Group Sequential Design with Multiple Interim Looks’ greatly extends the results of Glimm et al. ( 2010) and Tamhane et al ( 2010) which studied the problem of testing a primary and secondary endpoint, subject to a gatekeeping constraint, using a group sequential design (GSD) with K = 2 looks. This extends the methodology to provide for multiple (K>2) looks. The methodology is applied to the data from the RALES study (Pitt et al., 1999; Wittes et al., 2001).

How to handle conservativeness of Exact p-value?

Posted by Ashwini Joshi

Sep 18, 2017 7:38:45 AM

 

By Ashwini Joshi

For small sample data or rare events data, exact non-parametric tests perform better than asymptotic tests. But they come with the disadvantage of conservativeness. Many corrections have been suggested to reduce this conservativeness but none of them solve the problems entirely.  StatXact provides various methods of computing exact p-values. Depending upon the problem at hand, the user can decide which one to use.
Let’s consider a hypothetical example of stratified count data. The example shows two sample data with two strata. Events in Treatment1 are rare as compared to the ones in Treatment0. But the event rates are comparable.

Are Adaptive Designs the Answer to Oncology Development Success?

Posted by Cytel

Jul 26, 2017 10:05:39 AM

Sadly, clinical development of anti-cancer therapeutics faces particularly high rates of failure, even in the context of low success in drug development as a whole. Operating costs for oncology trials are also higher than those observed across the spectrum of clinical development.  In a recent article produced for the Pink Sheet ( a leading provider of  insights and analysis for biopharma leaders)  Cytel's Yannis Jemiai explored the key challenges facing oncology development today, and discussed how adaptive designs can help to improve researchers' probability of success. The article tackles the application of adaptive designs in both exploratory and confirmatory development and the potential benefits to stakeholders, including patients.

Jul 13, 2017 5:25:00 AM

By Tejasweeni Rajput

It’s been known for centuries that a picture can tell a thousand words. In an era of new technologies, and increasing volume of information, visualizations can help us to express complex data simply and effectively. Advanced technology is now available that allows statisticians and data scientists to drill down into the data sets to be analysed, and develop dynamic graphics that one can interact with. This marks a leap forward in decision-making capabilities from the static figures which have been traditionally available to us.
