PhUSE 2017 took place in Scotland’s capital city Edinburgh, 8th - 11th October, and brought together a range of experts to tackle the most pressing issues facing statistical programmers today. We found this year's event informative and well attended. In this blog we share some highlights from the sessions and posters the Cytel team attended. We will share Cytel's own contributions in a separate article.

In this blog we are excited to unveil a new project which we have been hard at work on over the last few months.
2017 marks a very special milestone for Cytel – our 30th anniversary. Cyrus Mehta and Nitin Patel founded Cytel in 1987 with an initial objective to solve a specific problem in computational statistics.

At the Chief Medical Officer Summit earlier this year, Cytel's Director of Quantitative Pharmacology and Pharmacometrics Cecilia Fosser, and Senior Director, Business Development, Chuck Gelb presented on how model-informed drug development (MIDD) techniques can improve decision-making and Probability of Success ( PoS) of clinical trial programs. In this blog, we share some highlights and the informative10-minute video replay of their talk which includes a modeling and simulation case study.

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.

At the East User Group meeting (EUGM) on 25th and 26th October, we will welcome a number of renowned industry speakers to discuss some of the most promising approaches in innovative trial design. Over the next few weeks, we will profile a number of the speakers and their talks. In this blog, we talk with Bob Beckman M.D in advance of his presentation ‘Design Concept for a Confirmatory Basket Trial'. This, the first part of a two-part interview will reveal Bob’s insights into basket trials and their potential. The second part of the blog will delve more deeply into the design concept itself and will be published after the East User Group Meeting. To learn more, read on.

Last month, Cytel statisticians headed to Baltimore for the Joint Statistical Meetings and shared some of their latest research and insights. In this blog we will summarize our highlights -both from Cytel contributions and the sessions Cytel delegates attended. We also provide access to the valuable slide decks from the Cytel authored presentations.

As a biometrics -focused CRO, Cytel regularly works across a program of studies, providing data consistency, and helping to minimize the oversight burden for the sponsor. In this case study, we describe our work with a client on two Phase 1 studies, and how we were able to carry a number of important efficiencies from the first study to the second.

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.

The Joint Statistical Meetings (JSM) is the largest and arguably most highly respected gathering of statisticians in the world. It will bring together over 6000 statisticians and runs from Saturday, July 29, to Thursday, August 3, 2017. With over 600 sessions, it can be a challenge to identify the most crucial ones to attend. To help out, we've asked some of the Cytel team for their top picks this year.
Topics: Oncology, Clinical Research Services, Statistical Programming, Statistical Analysis, Clinical Development Strategy, Adaptive Clinical Trials, Statistical Innovations in Clinical Development, biostatistics

With adaptive and innovative trial designs on the rise, operational implementation of interim analyses, including management of Independent Data Monitoring Committees is increasingly important. In this blog, we will share a case study of how Cytel provided a client with seamless Independent Data Monitoring Committee support encompassing committee selection and management, independent statistical services, and ACES software.

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.

The Adaptive Designs and Multiple Testing Procedures Workshop (ADMTP), the first joint meeting of the Adaptive Designs Working Group of the MRC Hubs for Trials Methodology Research and the joint ADMTP Working Group of the International Biometrics Society German and Austro-Swiss Regions, took place in Cambridge, UK last month.

The ethical benefits of adaptive clinical trials have been widely acclaimed: higher prospects for patients to be enrolled into the correct trial arm ; shorter trials for the most effective new therapies (see the early stopping outcome of the MUSEC trial) ; and enrollments commensurate with the needs of research, i.e. the last patient enrolled is not superfluous to a trial’s outcomes (e.g. according to one clinical biostatistician, “trial designs that learn more and treat better with less burden and sacrificing of patients”) .
However, the acknowledgement that ethical benefits exist is a separate question from the degree to which they exist when compared to a more traditional design.

Clinical data transparency improves decisions for all healthcare stakeholders including patients, caregivers, healthcare providers, payers, and regulators.
The topic of transparency and the process by which clinical trial data can be effectively anonymized and disclosed for use by researchers has become a hot topic in recent years. In this blog, we will discuss the broader context of patient privacy and the key considerations for biopharmaceutical companies in this area.

Since 2011 we have been celebrating Cytel's birthdays by holding an East Annual Symposium and User Group Meeting ( EUGM), alternating locations between Europe and the United States. Our keynote speakers have featured some of the industry's most eminent biostatistics thought leaders including Stuart Pocock, Dave DeMets, Chris Jennison, Sue Todd, and Franz Koenig. Each annual event has been a great success with a mix of scientific presentations, animated discussion, round tables and pre-conference software workshops.

The Population Approach Group in Europe (PAGE) represents a community with a shared interest in data analysis using the population approach. Each June, a meeting of the community is held at a different European location. At this year's meeting in Budapest, Hungary, Cytel's Director of Quantitative Pharmacology and Pharmacometrics, Cecilia Fosser, showcased innovative work on creating model based predictions of pharmacodynamic responses in ulcerative colitis patients. Fosser presented a poster Model based predictions of the PTG-100 pharmacodynamic responses in ulcerative colitis patients created in collaboration with colleagues from Protagonist Therapeutics.
In this blog we share the abstract and link to access an electronic copy of the poster .
