In Vivo Bioequivalence

The Laboratory of Bioequivalence and Molecular Biology provides full assistance in:

In vivo bioequivalence trial design
Preparation and review of Case Report Forms (CRFs)
Preparation of Informed Consent Form (ICF)
Preparation and translation of the Protocol/ammendments (in compliance with ANMAT, FDA, ICH, GCP)
Selection of the clinical study site and investigators
Regulatory approvals (Local Ethics Committee, IRB/IEC, National Regulatory agency ANMAT)
Drug Plasma concentration determination method

Final clinical and statistical report

The Laboratory’s facilities include two ThermoSeparation HPLCs, with autosampler and variable wavelength UV detector.

We also offer the possibility to analyze samples with other detection methodologies, such as GC, LC-MS/MS, RIA, EIA, etc.

HPLC and all other support equipment (centrifuges, scales, evaporator, etc) are periodically calibrated according to global and consistent Standard Operating Procedures (SOPs).

Similar or generics?

An original or innovator drug: is the one that contains a new active ingredient on which a complete research and development has been made. It is therefore the first, and sometimes the only one, that contributes to own data of security and therapeutic effectiveness. The developing, proprietary laboratory of the rights, commercializes it under a registered brand-name. Once the patent rights expired, the active ingredients contained in innovator products can be commercialized freely by different laboratories.

A generic drug: is a medicine with the same pharmaceutical form and equal qualitative and quantitative composition than the innovator product. It must demonstrate therapeutic equivalence by means of bioequivalence studies. The generic drug is interchangeable with the reference product since they have the same therapeutic effectiveness. They can only be commercialized once the patent of the innovator brand-name product has expired.

Design of a Bioequivalence Study

In the design of an In vivo Bioequivalence study, it is important to consider the following issues:

Study Purpose: drug development, local regulatory requirements, global market goals, marketing.
Drug characteristics: analytical method to be used for its quantization, half life of the drug that will determine the study timelines, eventual adverse events, etc. All these matters affect both study costs and ethical and regulatory issues.
Clinical Study Site and Analytical Laboratory selection: compliance with GCP, GLP, SOPs and certifications.
Study population: number of volunteers to be enrolled in the study, depending on the aims of the study and drug variability, which can be estimated from bibliography or a pilot study.
Study design: simple cross-over (AB/BA) or replicate (ABAB/BABA). The replicate design reduces the sample size (N) but lengthens study times. Group sequential design may also be proposed.


Bioequivalence Criteria

The European Agency of Medicaments (EMEA) accepts wider criteria like 75-133% and even 70-143%, especially for high variability drugs (more than 30% coefficient of variation).

Validated Methods

At the Laboratory of Bioequivalence and Molecular Biology we validate the analytical methods according to ICH guidances, evaluating the following parameters:

Selectivity / specificity
Precision (Precision, Intra-analysis precision, intermediate precision)
Linearity and range
Limit of Detection
Limit of Quantification
Accuracy / Recovery
Recovery of the plasma extraction method
Stability of the drug in plasma at -20oC, room temperature and freeze/thaw cycles

At present, we have validated analytical methods for the following antiretrovirals and we are currently undergoing validations for the simultaneous determination of antiretrovirals and other drugs according the need of our clients.
