Introduction
The hERG screening market size stands at USD 7.85 billion in 2025 and is forecast to reach USD 10.98 billion by 2030, expanding at a 8.60% CAGR. HERG screening is widely used to evaluate the potential risk of drug-induced cardiac arrhythmia, making it a routine requirement in preclinical safety workflows. Regulatory expectations around cardiotoxicity screening and the need to reduce late-stage drug failures continue to support the relevance of this market across global research settings.
According to the Mordor Intelligence HERG screening market analysis, demand is closely linked to growth in drug discovery pipelines, particularly in small-molecule therapeutics. Pharmaceutical sponsors increasingly rely on in vitro and cell-based assays to identify hERG-related liabilities before clinical stages. This focus on early-stage risk assessment supports consistent adoption of screening solutions across contract research organizations, academic research centers, and in-house discovery units, contributing to sustained hERG screening market growth.
Key Trends
-
Integration into Lead Optimization Workflows hERG screening is increasingly embedded into routine lead optimization stages, enabling early detection of cardiac risk and helping developers minimize downstream development delays and clinical-stage failures.
-
Emphasis on Early Cardiac Risk Identification Drug developers are prioritizing early safety assessment to align with regulatory expectations, reinforcing demand for standardized, reproducible hERG screening platforms.
-
Rising Adoption of High- and Medium-Throughput Screening High-throughput and medium-throughput approaches are gaining preference as they enable faster evaluation of large compound libraries, supported by automation for consistent and scalable data generation.
-
Growing Outsourcing to Specialized Service Providers Pharmaceutical companies, particularly small and mid-sized players, are increasingly outsourcing hERG screening to CROs with cardiac safety expertise to manage costs, improve flexibility, and ensure regulatory compliance.
