Phase Market Share (2025)
| Phase | Value Share (%) |
|---|---|
| Clinical | 61.3% |
In 2025, the clinical phase segment will still dominate the global large molecule bioanalytical testing services market with more than 61.3% share of the total market value. A clinical-stage test is, however, of growing importance as biopharmaceutical pipelines expand, and as biologics are being approved simultaneously across multiple therapeutic areas. This phase takes place under stringent regulatory supervision, involving the extensive testing of large molecules for safety, efficacy, immunogenicity and pharmacokinetics.
With sponsors striving to shorten drug development timelines and comply with the likes of the FDA, EMA, and PMDA, the need for high-quality clinical bioanalytical testing services has increased. Testing services during this step primarily involve the development and validation of complex assays and their application to sample analysis to support decision-making for dosage adjustments or monitoring adverse effects.
Rapid developments in monoclonal antibodies, fusion proteins, and gene therapies increased the demand for accurate large molecule analysis in the clinic. To address these needs, service providers are investing into the latest available LC-MS/MS instrumentation, ligand binding assays and high-throughput platforms.
And as innovation continues and more biologics move into late-stage development, clinical testing services will continue to represent a critical backbone of large molecule bioanalytical strategies.
Type Market Share (2025)
| Type | Value Share (%) |
|---|---|
| Pharmacokinetics | 57.8% |
As per projections, Pharmacokinetics (PK) will dominate the large-molecule bioanalytical testing services market by 2025, with a share of 57.8% of the overall market due to the rising incidence of chronic diseases. PK studies form the foundation for finding appropriate doses and therapeutic windows by predicting how a biologic is absorbed, distributed, metabolized and cleared from the body.
PK studies for large molecule drugs, e.g. monoclonal antibodies and therapeutic proteins, help us to optimize efficacy while reducing toxicity. They are key for the development of biosimilars, where comparative studies demand accurate and validated bioanalytical methods to compare with reference products.
Molecular complexes are increasingly making up the fabric of biologics, thus PK test patterns have also branched out to cover population-based mixture testing, live bioavailability evaluation, and other improved methods.
While these critical advances can be reached through the testing of small-molecule drugs (SMDs), the acute demand for biologics to target, such areas such as oncology, autoimmune disorders and rare diseases, has pushed PK testing of biologics to the forefront of preclinical and clinical development programs.
From multiplex assays and automation solutions to ML and AI tools that allow for the enhancement of data accuracy and interpretation, CROs and bioanalytical labs are continuously expanding their service repertoire.
And pharmacokinetics, with its key role in regulatory submissions and lifecycle management of large molecule drugs, continues to be the most significant and widespread type of testing carried out in the bioanalytical services space.
The growing elements of biologics, biosimilar and cell and gene therapies are filing extensive large molecule bioanalytical testing services market protocols. These services are essential for confirming the safety, efficacy, and pharmacokinetics of large molecule therapeutics including monoclonal antibodies, fusion proteins, and peptides.
Market drivers include an increase in outsourcing in drug development, increasing regulatory complexity, advances in ligand binding assays (LBA) and increasing use of LC-MS/MS quantification of complex biologics.
