On August 29th 2018, the FDA announced (1) that it would be establishing a Complex Innovative Trial Design (CID) Pilot Meeting Program. This follows the release earlier in August of a draft guidance (2) to help advance effective and innovative clinical trial designs early in drug development that can expedite new cancer therapies.

At Cytel we believe that expert statistical input has the power to shape the future of clinical development: de-risking portfolios, accelerating timelines, and increasing the probability of success.
In this blog we talk to Benjamin who lives in France, to find out more about his career path, achievements, current role at Cytel and his interests outside of work.

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

In 2011, Cytel organized its first East User Group Meeting (EUGM) in Paris. Since then, we have held an EUGM almost every year, alternating between locations in Europe and North America. These meetings have been a great success, giving opportunities for customers and industry colleagues to meet each other as well as with key opinion leaders, whilst learning more about our East software and...

We continue our case study series with this example of a Phase 3 design that uses Bayesian decision making combined with frequentist final analysis.
Clinical Development Background
Our biopharmaceutical client’s lead drug candidate is a late clinical-stage cancer immunotherapy for treatment of a rare oncology indication. Clinical development of therapies in this indication faces inherent...

In this blog, Adam Hamm, PhD, Director Biostatistics at Cytel shares some of the most important knowledge he uses in his day to day work as a biostatistician working extensively in oncology research. Adam has broad experience with statistical analysis and methodology over all phases (I-IV) of development, in particular working in the oncology arena.
As a Director of Biostatistics at...

Single ascending dose (SAD) and multiple ascending dose (MAD) studies are typically the first in human studies. They seek to gain information on safety and tolerability, general pharmacokinetic (PK) and pharmacodynamic ( PD) characteristics, and of course identify the maximum tolerated dose (MTD).
Conventionally, SAD and MAD studies were conducted separately, but increasingly are combined...

As a group, Cytel had over 40 successful regulatory interactions last year, many of which supported approvals for innovative trial design approaches. In this blog we look at some of the key success factors for regulatory interactions regarding adaptive designs.

The Global Cardiovascular Clinical Trialists Forum is a key event bringing together leading experts from across the spectrum of opinion leaders, clinical trialists, investigators, regulators, statisticians and practitioners to address the most pressing questions in cardiovascular clinical development today. At the December conference, eminent biostatisticians Cyrus Mehta and Stuart Pocock...

In April, we interviewed NIHR research fellow Munya Dimairo about the paper, ‘Adaptive designs undertaken in clinical research: a review of registered clinical trials’ (Hatfield et al, 2016), for which Munya was a co-author.
During the previous interview, we discussed the barriers to uptake of adaptive designs, and the urgent need for a cross-sector discussion and work on reporting guidance...

At a recent Pfizer/ Cytel seminar on rare disease and oncology development, Cytel’s Lingyun Liu presented innovative work on a patient enrichment design. In this blog, we share some design and operational considerations. This approach can help mitigate against underpowering of a clinical trial where there is uncertainty and heterogeneity of treatment effect among subpopulations.

While adaptive designs can deliver significant benefits to clinical development- including ethical benefits for patients, reduced costs, and improved likelihood of trial success- they are not suitable for every clinical trial. In making the assessment of whether or not to choose an adaptive design, trial planners need to weigh the strategic benefits against the practical implications.

Adaptive sample size re-estimation designs are an important part of the statistician's toolkit. In this first in a series of East Insight videos, Cytel Statistician Charles Liu walks us through the creation of an adaptive sample size re-estimation design in East with a 5 minute demo. Watch the video and download the accompanying slidedeck to recreate the steps.

Unlike statistics which has been around in some form for hundreds of years, pharmacometrics is, by comparison, a relatively new discipline and only entered the clinical development world in the last 30 years. Situated at the intersection of mathematical modeling, simulation, and big data, pharmacometrics leverages the best practices of translational research to generate clinical development...

Adaptive designs have the potential to accelerate clinical development, and improve the probability of trial success. While the principle is simple- to reduce the uncertainty in clinical development by obtaining additional information from the ongoing trial- the statistical methodologies can be complex, and expert support is often required to conduct the clinical trial design. There's also...

While some progress has been made in terms of scientific development in Neuroscience and Neuropsychiatry indications, the pace of translation into more effective treatments remains elusive.
At the recent Cytel seminar co-hosted with Pfizer, Abdul J. Sankoh of Sage Therapeutics presented on some of the challenges in these therapeutic areas and discusses strategies moving forward. He bases...
