Biomarkers are indicators of normal physiological and pathogenic processes, and/or responses to therapeutic interventions. They are fundamentally required in drug development, facilitating response monitoring, dose optimization, and for identifying variations in drug response among patients. In general, biomarkers are of vast significance to biopharma, diagnostics, personalized medicine, and overall healthcare industry. predicts that the biomarkers market valued at USD 58.6 billion in 2022 is expected to register a Compound Annual Growth Rate (CAGR) of 14.3% during the forecast period between 2023 to 2032. Biomarkers can be classified based on their nature, functional application. The BEST (Biomarkers, EndpointS, and other Tools) resource categorizes biomarkers into seven types as summarized in Figure 1.

Biomarker landscape assessment is a comprehensive overview that identifies, analyses, and categorizes biomarkers in disease or drug development, focusing on their specificity, sensitivity, and utility. It is pivotal in healthcare and translational research. In the latter, the process validates biomarkers identified in preclinical studies for clinical relevance, aiding in the development of diagnostic tools, prognostic indicators, and safe and efficacious therapeutic interventions. Biomarkers play essential roles in various aspects of drug discovery and development like in validation of potential drug targets, and assessment of the mechanism of action (MoA). It plays a crucial role in clinical trials by facilitating patient stratification, endpoint selection, and treatment monitoring, thereby enhancing trial efficiency and success rates. The systematic assessment of the biomarker landscape is pivotal for the progression of personalized medicine. It involves identifying and understanding biomarkers linked to specific disease subtypes and therapeutic interventions. Moreover, biomarkers help to optimize patient outcomes while concurrently mitigating adverse effects.

Major challenges in biomarker landscape assessment:

Biomarker landscape assessment for a drug, a disease, or a target is associated with multiple challenges. Some of the major challenges are listed in Figure 2.

Biomarkers play a crucial role in various aspects of healthcare, including disease diagnosis, prognosis, drug development, and monitoring therapeutic effects. Despite their immense potential, the conventional process of identifying biomarkers is often laborious and resource intensive. Both healthcare and pharmaceutical companies seek streamlined solutions to identify potential biomarkers and assess their translatability from pre-clinical models to clinical settings. Furthermore, the landscape of biomarker evaluation is undergoing a transformative shift with the integration of AI/ML models. These sophisticated algorithms enable the analysis of complex, high-throughput multi-omics, GWAS, and clinical data, revolutionizing biomarker assessment.

At Excelra, we offer tailored biomarker assessments designed to meet the unique requirements of our global Biotech and Pharma clients.
