New textbook chapter – Modelling Drug Induced Proarrhythmic Risk and a challenge for whole-heart computational modellers
A little note to say that a textbook chapter I wrote last year is now online and available as part of the Springer Reference work “Drug Discovery and Evaluation: Safety and Pharmacokinetic Assays“ The chapter is available here, and if … Continue reading
2021 CiPA in-silico Modelling Workshop
Abstract submission for the 2021 CiPA in-silico modelling meeting is open now. Continue reading
Arrhythmic risk: regression, single cell biophysics, or big tissue simulations?
On the 15th March I presented at an FDA public Advisory Committee hearing on the proposals of the CiPA initative. CiPA aims to replace the current testing for increased drug-induced Torsade de Pointes (TdP) arrhythmic risk, which is a human … Continue reading
Uncertainty quantification for ion channel screening and risk prediction
This post accompanies our new paper in Wellcome Open Research. Regular readers of this blog will know that I worry about uncertainty in the numbers we are using to model drug action on electrophysiology quite a lot – see our … Continue reading
Should I work with IC50s or pIC50s?
When you are expressing how much a drug inhibits something, it’s common to fit a Hill curve through a graph of concentration against % inhibition as shown here: In our case this is often ‘% inhibition’ for a given ionic … Continue reading
Are 30 compounds enough to test our simulations?
I’ve just contributed to a new review ‘Recent developments in using mechanistic cardiac modelling for drug safety evaluation’, which discusses where we are with using mathematical models of the electrical activity of cardiac muscle cells to predict whether new drugs … Continue reading
In-silico Action Potential Prediction Web Portal
This post is to announce that we are making our in-silico action potential prediction web portal (AP-predict) available for public use. The portal is free, you just need to register for an account. We’d be happy to have any feedback on … Continue reading
