Regulated Bioanalysis
What is the purpose of all this regulated bioanalysis?
Pharmacodynamics (PD) and
Pharmacokinetics (PK)
• Tandem Labs helps pharmaceutical companies obtain the necessary
information to make assessments regarding PD/PK of new drugs that are
being developed.
• Pharmacodynamics (PD) is the study of the biochemical and physiological
effects of drugs on the body (i.e. what the drug does to a body).
• Pharmacokinetics (PK) describes the drug concentration/time course in
body fluids resulting from administration of a certain drug dose (i.e. what
the body does to a drug).
• Tandem Labs use mass spectrometry to provide both qualitative and
quantitative information to our pharmaceutical partners during all phases
of the drug development process.

Drug Development
• Qualitative Analysis (by Mass Spectrometry)
•
In Vitro
•
High-throughput screening (lead generation, identification, and
optimization)
•
Metabolite Identification (cytochrome P450 enzymes)
• Quantitative Analysis (by Mass Spectrometry)
•
In Vitro
•
•
Solubility, plasma protein binding, permeability, plasma stability,
metabolic stability
In Vivo (preliminary animal studies)
•
Determine basic PK parameters (e.g. half-life, oral bioavailability ,
clearance and tissue distribution)
•
Qualified Assays / “Fit for Purpose”; less stringent acceptance criteria,
“quick and dirty”
Preclinical
Drug Development
• Quantitative Analysis (by Mass Spectrometry)
• Exploratory Toxicology (non-GLP)
• Dose range finding studies
• Different species and methods of administration
• Multiple dosing regimens
• Definitive Toxicology (GLP) – validated assays
• General toxicology studies
• Different species and methods of administration
• Immunogenicity studies with non-human primates (NHPs)
• Dose formulation analysis
• Safety is the key focus
Clinical Drug Development
• Clinical (Phases I-IV)
•
Quantitative Analysis (by Mass Spectrometry)
•
Validated Assays – not GLP; however, conducted under
the principles of GLP
•
First in Human
•
Single Ascending Dose (SAD)
•
Multiple Ascending Dose (MAD)
•

•
Special Populations
•
Elderly, renal impaired, hepatic impaired
•

•
Bioequivalence (BE)
Quantitative Analysis
by LC/MS
• Method Development
• Extraction conditions, chromatography conditions, MS parameters
• Very challenging; dictated by the chemistry of the analytes, maximum
sensitivity often required, instability, non-specific binding, tight time
pressures.
• Method Validation
• Highly regulated; A/P, stability, robustness, selectivity, matrix effects, etc.
• Constantly evolving requirements; additional tests
• Sample Analysis
• Tight time pressures, sample dilution, sample discrepancies with clinics, ISR

Mass Spectrometry
in Drug Development
Why is Mass Spectrometry such a good tool for these applications?
• Selective
• Allows the discrimination of a target analyte to the exclusion of other
interferences.
• Sensitive
• Can routinely detect analytes at ng/mL, pg/mL and sub pg/mL levels.
• Compatible with other separation techniques
• “hyphenated methods”
• GC-MS, LC-MS, UPLC-MS, CE-MS, etc.
• Robust / High throughput
• Versatile
Mass Spectrometry
in Drug Development
Why is Mass Spectrometry such a good tool for these applications?
• Selectivity
• Biological samples are first extracted (PPE, SPE, LLE, SLE)
• Chromatographic Separation (GC, HPLC, UPLC, Microflow LC)
• Multiple MS Techniques
• Full Scan
• SIM
• MS/MS (SRM, Product Ion, Precursor Ion, Neutral Loss)
• TOF/MS
• HRAM
Mass Spectrometry
in Drug Development
• MS/MS (tandem MS, triple-quadrupole MS) and Selected Reaction
Monitoring (SRM) is by far the most commonly used technique for
quantitative bioanalysis for PK/PD testing.
Mass Spectrometry
in Drug Development
• LC ionization techniques have also revolutionized
quantitative MS bioanalysis for PK/PD testing.
• Ionization is required for mass spectrometry (charged species;
m/z)
• GC/MS applications were limited to volatile, thermally stable
compounds for ionization.
• Atmospheric ionization techniques (ESI, APCI) removed these
limitations, allowing for LC/MS applications to expand to a wider
variety of compounds.

Mass Spectrometry
in Drug Development
• Types of compounds analyzed with LC/MS techniques:
• Small Molecules (MW < 800 amu)
• Traditional drugs, NCEs
• Large Molecules (MW > 800 amu; up to 10-40,000 Da)
• Biologics
• Peptides
• Oligonuclieotides
• SiRNA
• Lipids
• Biomarkers
• Proteins
