In this September 6, 2024 episode by SciPod Health and Medicine, SciPod summarizes the recent paper “Lecanemab for Patients with Early Alzheimer Disease: Bayesian Analysis of a Phase 2b Dose-Finding Randomized Clinical Trial” by Dr. Donald Berry (Founder of Berry Consultants) and Scott Berry (President of Berry Consultants).

Using FACTS to design a large 2-arm safety study, borrowing information from a previous trial, exploring alternative endpoints and using an enriched population.

A Phase 2 dose finding study using a Bayesian dose response model and response adaptive randomization across multiple doses and treatment regimens. Includes a presentation of the interim analyses from the actual trial that lead to the successful phase 3 trial of Lecanemab.

A randomized two arm study, using a utility weighted modified Rankin score and rules for adapting the enrolment criteria based on the location of the haemorrhage.

Designing a phase 1 dose escalation using Bayesian Logistic Regression Model (BLRM), with open enrolment (rather than cohort) using FACTS N-CRM.

Using FACTS to design a two-arm study where differences in adherence between the arms drive the effect size. Uncertainty in the effect size prompted spacing the interims to correspond to different sample sizes resulting in irregular interim analyses. Using a uses a finite mixture model from previous data on the analysis endpoint to justify the irregular interims.

Is this the most complex and most successful trial ever designed and run? Looking at the AWARD 5 trial for what became Eli Lilly’s Trulicity drug. The drug used response adaptive randomization, longitudinal modelling, dose response modelling and a utility function combining 4 endpoints. The trial selected a successful dose and switched early from phase 2 to a successful phase 3.

What makes GBM AGILE an innovative trial?

How is GBM AGILE paving the way for more innovative research?

Global Coalition for Adaptive Research released a series of Spotlight short videos presented by Don Berry on the GBM AGILE Trial.

Roger J. Lewis, MD, PhD, lectured on REMAP-ILD at HCOR scientific meeting (Sao Paulo, Brazil).

Dr. Melanie Quintana, statistical scientist and director at Berry Consultants, discussed innovative clinical trial design in ALS research at the 2023 MDA conference.

In this video we look at the different types of MAMS designs that includes Platform Trail designs. We look at the different design issues and analysis methods available for these sorts of trials. Originally aired November 9, 2023

In this video we look at designing Phase 2 Basket Trials where a treatment is explored in a large number of sub-groups (too many to be able to suitably power the trial in each sub-group).

In this video we look at designing seamless phase 2/3 trials, where a multi-arm phase 2 transitions when it can, selecting a dose and transitioning to a confirmatory phase 3.

In this video we look at designing response adaptive randomization (RAR) and arm dropping multi-arm phase 2 trials.

In this video we look at designing Group Sequential trials for confirmatory phase 3 trials, where the trial includes interims to stop early for efficacy and futility.

In this video we look at the issues around designing Phase 1 Dose Escalation trials in oncology, where the aim is to explore increasing dose levels up to a limiting rate of toxicities.

Looking at RAR with 3 aims: 1) A surprising amount of the literature considers just the two arm setting, when arguably the most interesting setting for this technique is the multi-arm one. 2) There have been a number of papers over the years critical of RAR and I’d like to add present some results in favour of RAR. 3)
