Stability Studies from Early Development to Late-Stage

Stability Tests

Stability testing studies evaluate the long-term stability of a drug product in its final primary packaging material under controlled storage conditions. In regular intervals, the chemical, physical, structural, and colloidal stability of the drug product is assessed by using stability indicating analytical methods.

Critical quality attributes (CQA) and relevant degradation pathways, as identified during preformulation and forced degradation studies, are monitored to assure the efficacy, quality, and safety of the drug product over its intended shelf-life. We perform such studies in accordance with ICH guidelines by using suitable climate chambers at controlled temperature and relative humidity (r.h.). We offer stability testing as part of formulation development projects, supply of pre-clinical material or as independent service package.

Storage Conditions

At Coriolis, we harness the knowledge gained in hundreds of projects to quickly obtain optimal test conditions for your drug substance, reflecting its major degradation pathways and assessing its critical quality attributes.

Standard storage conditions at Coriolis Pharma include the following*:

Frozen storage Storage according to ICH

-156 °C

-80 °C

-40 °C

-30 °C

-20 °C

2-8 °C

25 °C at 60% r.h.

30 °C

40 °C at 75% r.h.


*virtually any other temperature and relative humidity conditions can be offered as well, e.g., for kinetic studies.

Quality and Biosafety

Quality & Biosafety Level

We provide all our services with the highest quality standards. Each project is carried out by experienced scientists and every report or data presentation is comprehensively checked by a scientific reviewer. We offer stability tests under R&D and GMP conditions according to your development stage. Depending on your molecule we offer this service up to biosafety level S2.

Our Services for Long-Term Stability

Evaluating the long-term stability of a drug product is usually accompanied by other types of stability testing, such as forced degradation studies, in-use stability studies and comparability studies.


Forced degradation studies

Forced degradation studies are essential to understand the criticality of certain types of stress for the stability of drug substance. Our scientists develop and apply conditions, which simulate chemical, physical, or mechanical stress during production, transport and handling.

This knowledge is then applied to optimize the drug product formulation, design better primary packaging, and adjust procedures for production, transport, and handling.

In-use stability studies

In a clinical setting, a drug product may be diluted and encounters different surface materials before it is finally administered to the patient.

Therefore, our expert scientists assess the stability of a drug product during clinical use and handling, e.g., effects of dilution, compatibility with clinical diluents and materials, etc. We tailor such studies to the intended procedures and utilize a dedicated set of stability indicating analytical methods.

Comparability studies

The physico-chemical comparability, including comparability of stability profiles, is required for the development of biosimilar drug products, but can, among other scenarios, be crucial when comparing samples from different production processes or manufacturing facilities.

By using sensitive analytical methods and by applying relevant conditions for stability testing, we set up comparability studies specifically for your drug product. We provide the required experience and scientific know-how to detect critical differences between your samples with statistical relevance.
