Nucleic Acid and Gene Therapy Bioanalysis / Non-GLP
Specialised bioanalytical and characterization services for nucleic acid therapeutics and gene therapy programmes.
Nucleic acid therapeutics and gene therapy vectors represent some of the most analytically demanding drug modalities in modern pharmaceutical development. From antisense oligonucleotides (ASOs) and RNA interference (RNAi) therapeutics to mRNA therapeutics, viral vectors, and plasmid DNA, these advanced modalities require highly specialised bioanalytical platforms and extensive expertise in the applicable regulatory frameworks.
AMSbiopharma provides a comprehensive portfolio of bioanalytical and characterization services for nucleic acid therapeutics, supporting programmes from early preclinical pharmacokinetic/toxicokinetic (PK/TK) studies through CMC characterization and regulatory submissions.
All bioanalytical studies are performed under controlled quality systems, with method development and validation conducted in accordance with ICH M10 guidelines.

PK/PD Analysis of Oligonucleotides, Transgenes and Viral DNA/RNA
The bioanalysis of therapeutic oligonucleotides and gene therapy vectors in biological matrices requires analytical approaches with significantly greater complexity and sensitivity than those used for conventional small-molecule drugs. The structural similarity between the active therapeutic and endogenous nucleic acid species places exceptional demands on method sensitivity, specificity, and selectivity.
AMSbiopharma provides validated PK/PD bioanalytical services for oligonucleotide therapeutics, supporting preclinical and translational development programmes with robust quantitative data generated using state-of-the-art bioanalytical methodologies.
Key analytical capabilities
- Validated bioanalysis of antisense oligonucleotides (ASOs), RNA interference (RNAi) therapeutics, mRNA therapeutics, and viral DNA/RNA in biological matrices
- Bioanalytical capabilities for plasma, serum, tissue, and cerebrospinal fluid (CSF)
- ICH M10-compliant method development and validation
- Analytical support for tissue distribution and biodistribution studies
Our method development services begin with a comprehensive understanding of the analytical challenge: the physicochemical properties of the analyte, matrix complexity, regulatory context, and performance requirements. Based on this foundation, we design analytical methods optimized for sensitivity, specificity, accuracy, and robustness.
Method validation is performed in accordance with applicable regulatory guidelines — ICH Q2(R2) for quantitative pharmaceutical methods and ICH M10 for regulated bioanalytical methods — covering all required validation parameters: specificity, linearity, range, accuracy, precision, detection and quantification limits, robustness, and stability. Complete validation reports are prepared in a regulatory-ready format.
Method transfer services ensure that validated methods perform consistently in receiving laboratories, through an interlaboratory comparability exercise demonstrating equivalent performance. Transfer documentation complies with applicable regulatory requirements.
Key analytical capabilities:
– Method development for HPLC, UHPLC, GC, LC-MS/MS, HRMS, and other analytical platforms
– Full validation in accordance with ICH Q2(R2), ICH M10, and applicable specific guidelines
– Validation for small molecules, peptides, biologics, and oligonucleotides
– Method transfer with interlaboratory comparability and regulatory documentation
– Phase-appropriate validation strategies for early- and late-stage development programs

Plasmid DNA Isoform Analysis / GMP
Plasmid DNA is a critical component of the drug substance used in the manufacture of gene therapies and DNA vaccines. Plasmid quality, integrity, and isoform distribution are critical quality attributes (CQAs) that must be characterised and controlled throughout the manufacturing process. Regulatory authorities require comprehensive plasmid characterization data as part of the CMC package for gene therapy products.
AMSbiopharma provides validated analytical services for plasmid DNA isoform analysis, enabling the accurate quantification and relative distribution of supercoiled, open circular, and linear plasmid isoforms in both drug substance and drug product samples.
Key analytical capabilities
- Quantification and relative distribution of plasmid DNA isoforms (supercoiled, open circular, and linear)
- Analytical support for in-process quality control and drug substance testing
- Method development to support CMC development and process optimisation
- Applicable to gene therapy vectors and DNA vaccine development programmes
- Method development with appropriate sensitivity and specificity
