Digital Transformation of a Biopharma Quality Control Lab

Significance of the Topic

In recent years, biopharmaceutical quality control laboratories have faced growing regulatory pressure to transition to paperless environments. This digital transformation supports faster turnaround times, robust data integrity, and optimized resource utilization. By integrating cloud-based data management and laboratory information systems, QC labs can enhance compliance, traceability and overall operational efficiency without compromising analytical quality.

Objectives and Study Overview

This work demonstrates the deployment of a small-scale monoclonal antibody (mAb) release testing laboratory fully digitalized through Agilent OpenLab CDS and SLIMS. Two chromatography systems were dedicated to aggregation and charge variant assays, representing critical quality attribute monitoring. The primary goal was to streamline the workflow from sample submission to final report generation, minimizing manual steps and maintaining regulatory alignment.

Used Instrumentation

• Agilent 1290 Infinity II bio high-speed pump (G7132A)
• Agilent 1290 Infinity II bio flexible pump (G7131A)
• Agilent 1290 Infinity II multisampler with cooling option (G7137A)
• Agilent 1290 Infinity II multicolumn thermostat with bio heat exchanger (G7116B)
• Agilent 1290 Infinity II diode array detector (G7117B)
• SLIMS 6.9
• OpenLab CDS client/server 2.7 and Sample Scheduler 2.7
• Microsoft Azure cloud servers

Methodology and Cloud Infrastructure

A network architecture connected onsite LC instruments to cloud-hosted OpenLab CDS and SLIMS via the corporate LAN and Agilent instrument controllers. SLIMS managed sample registration, test requests, resource inventory and protocol execution. Mobile phase preparation and sample sequencing were implemented as visualized SLIMS workflows, automatically deducting reagents and tracking consumable status. Chromatography methods and processing templates were preconfigured and triggered directly from SLIMS, ensuring seamless transfer of method parameters to OpenLab instruments.

Main Results and Discussion

The integrated digital workflow enabled real-time monitoring of mAb aggregation and charge variants. Sample A01 met all predefined specifications, while sample A02 exceeded acidic and basic variant limits, triggering an out-of-specification alert. Automated rule-based evaluation and centralized archiving provided clear audit trails and facilitated rapid decision making. User access control and standardized SOP enforcement reduced variability and enhanced data integrity.

Benefits and Practical Applications

• Shortened turnaround times through automated data flow
• Comprehensive resource management of columns and reagents
• Improved compliance with electronic SOPs and audit readiness
• Enhanced traceability via versioned data archiving
• Reduced manual errors in sample preparation and instrument operation

Future Trends and Opportunities

Next-generation lab informatics will leverage artificial intelligence for predictive analytics, real-time instrument performance monitoring and automated anomaly detection. Increased adoption of Internet of Things sensors and edge computing will further bolster data fidelity. Cloud-first architectures will enable greater scalability, collaboration and regulatory reporting capabilities across global QC networks.

Conclusion

This study illustrates a practical blueprint for fully digitalizing a biopharma QC lab. By integrating SLIMS and OpenLab CDS in a cloud-based environment, the laboratory achieved robust sample management, resource tracking and data integrity. The resulting end-to-end workflow improves efficiency, compliance and decision support, laying the groundwork for future innovation in pharmaceutical analytics.
