Pharmaceutical Stability Studies and Services

Pharmaceutical Stability Studies and Services

We help our clients understand the stability and quality of drug products (finished formulation) by providing stability testing services as per ICH guidelines.

We aim at providing pharmaceutical stability solutions that include the study of product-related factors that influence the quality of a drug, such as the:

Interaction of an API with excipients Identification and prevention of degradation pathways in product Container closure systems

All stability samples are stored under controlled conditions such as incubators and stability chambers for accelerated or long-term or intermediate stability studies. The suitability of a drug substance or a drug product for its intended use is defined by attributes such as identity, strength, and purity.

Thermal Stability

In general, the drug substance and drug product are evaluated under storage conditions (with appropriate tolerances) that test their thermal stability and if applicable, their sensitivity to moisture. The storage conditions and the lengths of studies are defined by regulatory guidelines.

Conditions

Drug Substances:

  • Long term: 25°C ± 2°C/60% RH ± 5% RH or 5°C ± 3°C
  • Accelerated: 40°C ± 2°C/75% RH ± 5% RH

Drug Product:

  • Long term: 25°C ± 2°C/60% RH ± 5% RH or 30°C ± 2°C/75% RH ± 5% RH
  • Intermediate: 30°C ± 2°C/65% RH ± 5% RH
  • Accelerated: 40°C ± 2°C/75% RH ± 5% RH

Photostability

The intrinsic photostability characteristics of a new drug substance or drug product are assessed to demonstrate that light exposure does not result in unacceptable change. Usually, we conduct photostability testing for a single batch of the material selected as described under the selection of batches in the parent guideline. Under some circumstances, these studies can be repeated if certain variations and changes are made to the product (such as formulation and packaging). The repeat study helps us understand photostability characteristics determined at the time of initial filing and the type of variation and/or change made.

A systematic approach to photostability testing is recommended, based on studies such as:

  • Tests on the drug substance
  • Tests on the exposed drug product outside of the immediate pack
  • Tests on the drug product in the immediate pack
  • Tests on the drug product in the marketing pack

In-use Stability

Our in-use stability testing services help to establish the period during which a multi-dose product can be used while retaining quality within an accepted specification once the container is opened. The continued integrity of products in multi-dose containers after the first opening is an important quality issue.

Neoantigen Specific T cells For Cancer Immunotherapy

Neoantigen specific T cells for cellular cancer immunotherapy An effective anti-tumor immune response in human is marked by presence of T cells reactive against neoantigens. Neoantigens are HLA-bound unique peptides arise from tumor-specific somatic mutations. Neoantigens are highly immunogenic because they are not present in normal tissues and hence...

Alternate end-game strategies towards Nirmatrelvir synthesis: Defining a continuous flow process for the preparation of an anti-COVID drug

2023

Scalable alternate end-game strategies for the synthesis of the anti-COVID drug molecule Nirmatrelvir (1,PF-07321332) have been described. The first involves a direct synthesis of 1 via amidation of the carboxylic acid 7 (suitably activated as a mixed anhydride with either pivaloyl chloride or T3P) with the ...
