Is this compound cardiotoxic, and by what mechanism?

Start with a fast in-silico read on a validated human iPSC-cardiomyocyte model: which ion currents reproduce the signal, whether it is dose-dependent and reversible, and the one experiment that would confirm it. Before you commit wet-lab time.

what we offer
in-silico cardiac read

A fast mechanism read on your compound's cardiac signal (QT, QRS, or repolarization change). It runs on a validated iPSC-cardiomyocyte action-potential model (Kernik-Clancy 2019) with a virtual cell population, and returns the ion-current change that reproduces the effect, the dose-response and reversibility, and the assay that would confirm it. No wet lab. Days to a first read.

ion-channel panel read

Bring your ion-channel panel (hERG, Nav1.5, Cav1.2). We run it through the same iPSC-cardiomyocyte model and return which currents are consistent with your signal, ranked, on the human iPSC-CM substrate, with the identifiability limits stated per current.

co-designed wet confirmation

When the read points to a wet answer, we design the iPSC-cardiomyocyte pilot around your question and run it through partner labs (paired morphology and transcriptomics, or functional electrophysiology). You keep your results.

Cardiac safety is moving to human iPSC-cardiomyocytes and in-silico models, the path the FDA's 2025 new-approach-methods roadmap prioritizes. We start in silico, on a validated cardiomyocyte model, so you get a mechanism read in days without standing up an assay. When a read needs empirical confirmation, we design the wet pilot around your question and run it through partner labs. Public iPSC-CM cardiotoxicity data is narrow: the widely-cited sets cover a single drug (Burridge 2016, doxorubicin) or a single drug class (Sharma 2017, tyrosine-kinase inhibitors), and none pairs morphology with transcriptomics across a broad panel. We start in silico, and generate the confirmatory wet data only when a read calls for it.

what a read delivers
what's in a read

The mechanism: the ion-current change (for example hERG/IKr, Nav1.5, or Cav1.2) that reproduces your signal, with the competing hypotheses ranked.

Dose and reversibility: the dose-response and washout behavior the model predicts.

The confirming experiment: the single assay that would discriminate the causes, from an identifiability analysis of the model.

Limits of the read: a single-cell model is a proxy for tissue-level conduction, so the read ranks and bounds causes rather than proving one, and states per current what it can and cannot resolve.

how an engagement runs
Week 0
In-silico read
Your compound's signal in, a mechanism read out on the validated iPSC-CM model. Days, no wet lab.
->
if needed
Confirmatory design
The identifiability analysis names the one assay that would confirm the cause.
->
weeks
Co-funded wet pilot
We design and broker the iPSC-CM pilot through partner labs. You keep your results.
inside the wet pilot, when it runs
01 design
Scoped design
The pilot is designed around the confirmatory question from the in-silico read.
02 execute
Partner lab
The pilot runs at a partner CRO. Perturb designs it and reads the result.
03 measure
Multimodal
Cell Painting and DRUG-seq, co-measured on matched parallel arms (morphology + transcriptomics).
04 analyze
Mechanism
Results are read against the model to confirm or refine the mechanism.
-> The read designs the pilot; the pilot confirms the read.

The read designs the pilot. The in-silico read names the confirmatory question, so the wet pilot targets the mechanism rather than running a broad screen.

interactive model
open the interactive cardiomyocyte model ->

Knock down a cardiac gene and watch the action potential change in real mV and ms, computed by a published, validated electrophysiology model (Kernik-Clancy 2019). Each channel case reproduces a known channel-disease phenotype.
