New Approach Methodologies (NAMs) for cardiac safety assessment

Future-proof your cardiac safety strategy with human-relevant data

The drug discovery industry is undergoing a significant shift towards New Approach Methodologies (NAMs) that provide more predictive, human-relevant data while reducing reliance on traditional animal models. Regulatory agencies, pharmaceutical companies and biotechnology organisations are increasingly incorporating NAMs into non-clinical development to improve decision-making, strengthen evidence packages and support the development of safer medicines. As the industry moves towards more predictive, human-relevant approaches, organisations are seeking partners that can help them implement NAMs effectively and generate data that supports confident development decisions.

At Metrion, we help clients integrate human induced pluripotent stem cell-derived cardiomyocyte (hiPSC-CM) assays into modern cardiac safety assessment strategies through advanced electrophysiology and human-relevant in vitro models. By combining clinically relevant cellular models with deep expertise in cardiac ion channel pharmacology, we can generate high-quality electrophysiology data that provide mechanistic insight into cardiac ion channel function and proarrhythmic risk, helping clients make more informed development decisions.

For many organisations, adopting these approaches provides a competitive advantage through earlier identification of potential cardiac liabilities, improved confidence in candidate selection, and the potential to shorten development timelines while reducing costly late-stage failures.

What are New Approach Methodologies (NAMs)?

New Approach Methodologies (NAMs) encompass a broad range of innovative technologies designed to improve the prediction of human biological responses. These approaches include human cell-based assays, advanced in vitro models, computational methods and integrated testing strategies that can complement or, in some cases, reduce reliance on traditional animal studies.

In cardiac safety assessment, NAMs provide an opportunity to evaluate compound effects using human-derived systems that better reflect human cardiac electrophysiology and ion channel pharmacology than many traditional experimental models.

Why are NAMs important for cardiac safety?

Cardiac safety remains one of the most critical areas of risk assessment during drug development. Unexpected cardiovascular liabilities can lead to programme delays, regulatory challenges and costly late-stage attrition.

Traditional approaches remain essential components of non-clinical development but they may not always accurately predict human-specific cardiac responses. Human-relevant NAMs, especially human induced pluripotent stem cell (hiPSC) derived cardiomyocytes can help address this challenge by providing insight into compound effects on cardiac ion channels and electrophysiological function earlier in development.

By incorporating NAMs into cardiac safety strategies, drug developers can:

  • Identify cardiac liabilities earlier in discovery
  • Improve confidence in compound progression decisions
  • Improve prediction of QT prolongation risk
  • Generate more human-relevant safety data
  • Support more efficient non-clinical development programmes
  • Help reduce reliance on animal-intensive studies
  • Strengthen IND-enabling evidence packages
  • Reduce the risk of costly late-stage failures

Action potential waveform analysis in human iPSC-cardiomyocytes enables mechanistic assessment of multichannel cardiac effects

Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), combined with optical voltage imaging, provide a powerful platform for evaluating integrated multichannel cardiac effects in a human-relevant model. In our study, concentration-dependent changes in action potential waveforms reflected known ion channel pharmacology and distinguished compounds with similar action potential prolongation but different underlying mechanisms. When integrated with automated patch clamp data, this approach provides deeper mechanistic insight into proarrhythmic risk and demonstrates how complementary NAMs can strengthen modern cardiac safety assessment.

Metrion's NAMs-enabled cardiac safety capabilities

Metrion combines deep ion channel expertise in ion channels with industry-leading electrophysiology capabilities to help clients implement modern, human-relevant cardiac safety assessment strategies.

Our capabilities include:

Clinically translatable human iPSC-derived cardiomyocyte assays

Human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes provide a physiologically relevant model for evaluating drug-induced effects on cardiac electrophysiology. Identifying potential cardiac liabilities early is essential for reducing risk during drug development.

Our hiPSC-derived cardiomyocyte assay, performed using the VOLTA optical platform, provides clinically relevant data to help predict the effects of novel compounds on cardiac electrophysiology, including the assessment of QTc and QRS prolongation before clinical studies begin.

By generating translational safety data at an early stage, the assay enables more confident decision-making when prioritising compounds. Early identification of cardiac safety concerns helps minimise late-stage attrition, reducing development costs and accelerating the progression of the most promising candidates.

Frequently asked questions

What are New Approach Methodologies (NAMs)?

NAMs are innovative scientific approaches that improve the prediction of human biological responses using technologies such as human cell-based assays, advanced in vitro models, computational modelling and integrated testing strategies.

How can NAMs improve cardiac safety assessment?

NAMs can provide more human-relevant and mechanistically informative data, helping researchers identify cardiac liabilities earlier and make better-informed development decisions.

Do NAMs replace traditional safety pharmacology studies?

Not currently. NAMs are generally used alongside established safety pharmacology approaches to provide complementary data and strengthen overall risk assessment strategies. Their role continues to evolve as regulatory acceptance increases.

How do NAMs help reduce animal use in drug discovery?

NAMs can provide human-relevant mechanistic data that complements traditional non-clinical studies and may help reduce reliance on animal-intensive testing approaches. By generating earlier insight into compound safety and efficacy, NAMs can support more informed decision-making and contribute to leaner development programmes.

How can Metrion support NAMs-based cardiac safety strategies?

Metrion provides human-relevant cardiac safety assays, ion channel screening and electrophysiology expertise that help clients generate high-quality data for modern cardiac safety assessment programmes.

Can NAMs help strengthen IND submissions?

Human-relevant mechanistic data generated using NAMs can provide valuable supporting evidence within broader non-clinical development programmes and help increase confidence in regulatory submissions.

Supporting ion channel biologics discovery: Why functional electrophysiology is critical

Biologic modalities may offer opportunities to achieve levels of subtype selectivity that can be difficult to obtain using traditional small molecules, particularly across closely related ion channel family members. This may enable more precise modulation of disease-relevant targets while potentially reducing unwanted off-target activity.
