Quality Without Compromise

Built on a Culture of Quality

At OneSource, quality is not a checkpoint. It is a continuous, embedded function across development, manufacturing, and supply.

Our operations are designed to deliver consistent, reliable outcomes by integrating quality into every stage of the product lifecycle. From early development through commercial production, teams work within a unified framework that prioritizes compliance, process control, and data integrity.

This approach ensures that products meet global regulatory expectations while maintaining the consistency required for successful commercialization.

An Approach to Quality Focused on Consistency and Compliance

Our quality policy is centered on delivering products that consistently meet customer expectations while adhering to the highest global regulatory standards.

This is achieved through a combination of structured systems, disciplined execution, and continuous oversight. Rather than reacting to issues, our teams are trained and empowered to identify risks early and maintain control throughout development and manufacturing.

Quality Management Systems Designed for Control and Transparency

OneSource operates a robust, digitally enabled Quality Management System (QMS) that supports governance, traceability, enhanced visibility, and structured oversight across sites.

Quality systems are built to ensure:

- Proactive risk identification and mitigation
- Consistent execution across facilities and programs
- Full traceability of materials, processes, and outcomes

These systems are supported by integrated digital platforms, including enterprise resource planning, document management, training systems, and laboratory information management systems. Together, they provide a unified view of quality across operations and enable informed decision-making.

A digital-first approach to quality

Data-driven quality management with periodic analytics and quality metrics

Integrated systems across manufacturing and laboratory operations

Transparent, traceable data supporting audit readiness

cGMP Quality Control Across the Product Lifecycle

Quality control at OneSource spans the full lifecycle of drug substance and drug product development and manufacturing.

Analytical and quality teams work closely with development and manufacturing groups to ensure that methods are transferred, validated, and executed consistently across all facilities. This includes:

Raw material testing and qualification
In-process testing and monitoring
Final product release testing
Stability studies aligned with global guidelines

Each facility is equipped with dedicated Quality Control laboratories to support these activities, ensuring that testing is performed with speed, accuracy, and consistency.

Comprehensive Microbiological Control

Maintaining sterility and controlling contamination are critical across multiple modalities supported by OneSource.

Dedicated microbiology laboratories support:

Environmental monitoring across classified manufacturing areas
Microbial identification and culture handling
Endotoxin and bioburden testing
Sterility assurance programs

These capabilities enable consistent control of microbiological risk and support the production of high-quality sterile and non-sterile products.

Inspection Readiness as a Standard Practice

Inspection readiness is not an event, but an ongoing state.

Through continuous monitoring, internal audits, and structured quality reviews, OneSource maintains readiness for regulatory inspections at all times. This is reflected in a strong track record of successful inspections across global regulatory agencies.

By combining disciplined systems with experienced teams, OneSource ensures that quality and compliance are sustained consistently, not just demonstrated when required.
