ICH Q1A–Q1F Stability Study Protocol & Chamber Pull Automation Guide for QC Labs

International Council for Harmonisation (ICH) guidelines (Q1A(R2) for new drug substances, Q1B for photostability, Q1C for new dosage forms, Q1D for bracketing and matrixing, Q1E for data evaluation) dictate long-term (25°C/60% RH, 30°C/65% RH), intermediate (30°C/65% RH), and accelerated (40°C/75% RH) testing programs.

Managing hundreds of stability protocols, pull dates (1, 2, 3, 6, 9, 12, 18, 24, 36, 48, 60 months), orientation states (upright, inverted), and packaging types on manual spreadsheets frequently leads to missed pull windows, delayed testing, and compromised regulatory submissions.

Novaqis LIMS transforms stability operations into a governed, automated workflow: • Protocol Designer: Define study types (real-time, accelerated, zone IVb climatic zones, photostability) with pre-configured testing matrices and sampling intervals. • Dynamic Pull Calendar & Notifications: Automated generation of sample pull worklists with configurable grace periods (e.g. ±1 day for 1-month pulls, ±3 days for 12-month pulls) and automated email/SMS alerts to QC stability analysts. • Chamber Inventory & Spatial Mapping: Track stability sample containers across specific rack, shelf, and tray locations inside temperature/humidity-controlled chambers.

Novaqis LIMS automatically plots assay degradation, impurity growth, and dissolution trends over time, executing linear and poolability regression analysis (95% confidence intervals) to mathematically project expiration dates and shelf-life claims for global regulatory dossiers.
