Dossiers and Stability Studies

Stability and BA/BE studies for pharmaceuticals and biologicals, plus eCTD dossier preparation for US, EU and other regulated and emerging markets worldwide.

Through active involvement in manufacturing and direct interaction with laboratories and manufacturers, GNH USA can undertake internationally acceptable stability studies, BA/BE studies and eCTD dossier preparation.

Stability & BA/BE

Internationally acceptable study quality

Stability studies for Zone 4 countries

ICH-compliant stability protocols for high-temperature/high-humidity zones.

BA / BE studies

Bioavailability and bioequivalence studies for pharmaceuticals and biologicals.

Bioavailability

BA data for a formulation provides an estimate of the relative fraction of an orally administered dose absorbed into the systemic circulation. BA studies also yield pharmacokinetic information on distribution, elimination, the effects of nutrients, and dose proportionality.

Bioequivalence

BE and product-quality BA focus on the release of a drug substance from a drug product and subsequent absorption into the systemic circulation.

CTD dossier preparation

Dossiers that meet the most demanding standards

Years of preparing dossiers for products manufactured by us across many countries — competent and well-equipped to deliver eCTD dossiers for EU, US and other regulated markets, as well as semi-regulated and unregulated markets.
  • eCTD format

    Electronic Common Technical Document compatible with FDA, EMA and equivalent regulators.

  • Regulated markets

    EU and US standards — quality, safety, efficacy and module 3 strength.

  • Semi-regulated & unregulated

    Dossiers tuned to local registration requirements outside the major regulators.

  • Manufacturer-grade insight

    Our own manufacturing experience informs the dossiers we prepare.

FAQ

Frequently asked questions

What is an eCTD dossier?

The electronic Common Technical Document (eCTD) is the standard electronic format for submitting regulatory dossiers. GNH USA prepares eCTD dossiers compatible with the FDA, EMA and equivalent regulators.

Which markets do you prepare dossiers for?

We prepare dossiers for regulated markets such as the US and EU, as well as semi-regulated and unregulated markets, tuned to each market's local registration requirements.

What is the difference between bioavailability and bioequivalence studies?

Bioavailability (BA) studies estimate the fraction of an administered dose that reaches systemic circulation, while bioequivalence (BE) studies compare a product's drug release and absorption against a reference. GNH USA undertakes both for pharmaceuticals and biologicals.

Do you offer stability studies for hot and humid climates?

Yes. We run ICH-compliant stability studies, including Zone IVb protocols for high-temperature and high-humidity countries.

Why choose a partner with manufacturing experience for dossiers?

GNH USA's direct involvement in manufacturing and its laboratory relationships inform the dossiers we prepare, improving the quality and acceptability of submissions.
