Guidelines for Stability Testing of Orphan Drugs

1) Purpose

The purpose of this SOP is to outline the procedures for conducting stability studies on orphan drugs. Orphan drugs, designed to treat rare diseases, require stability testing to ensure their safety, efficacy, and quality under various storage conditions throughout their shelf life.

2) Scope

This SOP applies to all orphan drugs produced, handled, or stored by the organization, including oral, injectable, and other dosage forms. It is intended for personnel involved in formulation development, quality control, and regulatory affairs.

3) Responsibilities

Formulation Scientist: Responsible for designing the stability study protocol and selecting appropriate testing parameters.

Quality Control (QC) Team: Responsible for conducting stability tests according to the approved protocol and documenting results.

QA Team: Responsible for reviewing data, ensuring regulatory compliance, and approving the final stability report.

4) Procedure

4.1 Study Design:

1. Identify stability-indicating parameters (e.g., potency, purity, dissolution rate, and content uniformity)

   relevant to the orphan drug formulation.
2. Select appropriate analytical methods to evaluate these parameters.
3. Define storage conditions (e.g., room temperature, refrigeration) based on product characteristics and regulatory guidelines.
4. Develop a study protocol outlining the objectives, sampling schedule, and analytical methods to be used.

4.2 Sample Preparation:

1. Prepare samples from representative production batches and label them with batch
