HERG Screening Market Overlook

Market Overview

The global HERG screening market was valued at USD 2,082.76 million in 2023 and is expected to grow at a CAGR of 12.7% during the forecast period.The global HERG (human Ether-à-go-go-Related Gene) screening market is witnessing a strong upward trajectory, driven by the growing need for early detection of cardiac safety risks in drug development. HERG screening is a critical component in the pharmaceutical industry’s effort to identify compounds that could potentially induce cardiac arrhythmias, especially Torsades de Pointes, by inhibiting the HERG potassium ion channel. As cardiovascular safety remains a key regulatory concern, HERG screening has become an essential tool in preclinical and clinical drug assessments.

With continuous innovation in in vitro electrophysiology, automation, and predictive modeling, the HERG screening market is rapidly evolving. Regulatory agencies like the FDA and EMA have emphasized the importance of cardiac safety evaluation in new drug submissions, creating a standardized and regulated environment for HERG assays. As drug development pipelines grow and personalized medicine becomes more prominent, demand for robust screening systems is expected to rise significantly.

Key Market Growth Drivers

1. Increased Focus on Drug Safety

Cardiotoxicity is one of the leading causes of drug withdrawals from the market, making safety screening essential in early drug discovery stages. HERG channel inhibition is a well-documented indicator of potential proarrhythmic effects. With regulators demanding in-depth cardiac evaluations for any new molecular entity (NME), HERG screening has transitioned from being a recommended practice to an essential safety requirement.

2. Stringent Regulatory Requirements

Global regulatory bodies, including the International Council for Harmonisation (ICH), have established specific guidelines—particularly ICH S7B and E14—that stress the importance of HERG testing. These frameworks mandate preclinical and clinical evaluations of a compound’s potential to affect cardiac ion channels. Pharmaceutical firms must comply with these stringent benchmarks to avoid delays or failures in the drug approval process.

3. Technological Advancements in Screening Platforms

Modern HERG screening systems have evolved to include automated patch-clamp systems, fluorescence-based high-throughput screening, and induced pluripotent stem cell (iPSC)-derived cardiomyocyte models. These innovations reduce manual labor, increase assay reliability, and provide better physiological relevance. The ability to generate large volumes of data with high accuracy makes advanced HERG screening tools highly desirable across pharma and biotech companies.

4. Rising Investments in R&D and Personalized Medicine

The growing investment in R&D for targeted therapies and precision medicine has fueled demand for predictive safety pharmacology tools. HERG screening offers valuable insights into how drugs will behave across different genetic profiles, thereby supporting safer and more effective therapeutic development. As pharma companies strive to reduce late-stage attrition, the integration of robust cardiac screening early in the pipeline is becoming increasingly vital.

Market Challenges

1. High Costs of Advanced Screening Technologies

While new HERG screening platforms offer higher precision and throughput, they come with significant capital investment. The cost of automated electrophysiology equipment, software licenses, and skilled labor can be prohibitively expensive for small- to mid-sized research organizations. This cost barrier often leads to outsourcing HERG screening to specialized CROs (Contract Research Organizations), potentially slowing down internal workflows.

2. Complexity of Cardiac Electrophysiology

HERG assays are only part of a broader cardiac safety picture. The interpretation of data from in vitro HERG inhibition studies must be complemented by other ion channel tests and in vivo studies. Variability in cell lines, assay protocols, and temperature sensitivity also adds to the complexity, which may lead to inconsistent results across labs. Improved standardization is still a work in progress.

3. Limited Adoption in Emerging Economies

Although awareness of HERG screening is growing globally, adoption in emerging markets lags behind due to lower R&D spending and infrastructure constraints. Many pharmaceutical and biotech firms in regions like Latin America, Africa, and parts of Asia may prioritize more immediate challenges over complex safety screening processes unless exporting to more regulated markets.
