Bioanalytical Solutions for Clinical Trials
With over two decades of experience, Synexa is a bioanalytical CRO operating at the forefront of scientific innovation, offering a wide range of bioanalytical solutions, including mass spectrometry (LC‑MS/MS), immunoassays, radiopharmaceutical bioanalysis, and custom assay development to support small and large molecule drug development.
Our integrated bioanalysis services span the full drug development lifecycle, from discovery and preclinical through to clinical phases, providing comprehensive PK, TK and PD analysis, immunogenicity assessment, and assay development. We generate robust, accurate, and regulatory-ready data to accelerate and de-risk your therapeutic pipeline.

Bioanalytical Services

Mass Spectrometry
Precise, sensitive quantification of small and large molecules using mass spectrometry platforms to support robust pharmacokinetic and biomarker analysis.

Immunoassay Services

Radiopharmaceutical Bioanalysis
Specialised radiopharmaceutical bioanalysis solutions enabling accurate measurement of radiolabelled compounds, delivering critical comprehensive insights into biodistribution, pharmacokinetics, and safety profiles.

Biosimilars
Support biosimilar development with bioanalytical, immunogenicity, and PK services, delivering robust comparability data to demonstrate safety, efficacy, and regulatory confidence.
Bioanalytical Assays
Immunogenicity Testing
Assessing the immunogenicity of therapeutic drugs is particularly important when considering the significance of anti-drug antibodies (ADA) in clinical studies. Our customisable assay panels are developed through rigorous method development and validation to ensure regulatory and sponsor-specific requirements are met, whilst simultaneously providing useful, clinically relevant data to facilitate the progression of your therapeutic pipeline.
Pharmacodynamic (PD) Assays
Our PD assays, renowned for their sensitivity and specificity, are custom-developed and validated by our expert scientists, in collaboration with your team and according to your requirements. Assays are compatible with sample material from an extensive array of matrices and therefore are suitable for large-scale, high-throughput clinical bioanalysis studies.
Pharmacokinetic (PK) and Toxicokinetic (TK) Assays
Synexa’s comprehensive Pharmacokinetic (PK)/Toxicokinetic (TK) bioanalytical services meticulously assess absorption, distribution, metabolism, excretion and kinetics of toxic substances. Our expertise ensures that customers receive crucial insights, optimising drug safety and efficacy for successful therapeutic development.
Regulatory Expertise
Our Experts Help You Navigate Complex Regulatory Requirements
Synexa supports pharmaceutical and biotechnology companies with regulated bioanalytical services aligned with global quality and compliance standards. Our GCP/GLP-certified and GCLP-accredited labs follow internationally recognised guidelines, including those of the FDA, EMA, MHRA, and ICH, and are supported by robust quality systems. Our facilities are regularly inspected by leading regulatory authorities, including the MHRA and FDA. We also welcome client audits and inspections, reinforcing our commitment to transparency, integrity, and delivering reliable, high-quality data.
