Lot & Final Drug Product Release Testing

To ensure that client biopharmaceuticals, pharmaceuticals and medical devices are produced according to the strict requirements of Good Manufacturing Practice (GMP) and that the release testing packages are carefully designed to demonstrate that compliance, we provide a full range of product release support, from addressing biosafety concerns and analyzing potency using suitable bioassays, to determining purity and other biochemical characteristics. Our commitment to providing rapid turnaround times for all testing helps minimize the period between production and release.

We work closely with operational staff, offering flexibility to meet clients' manufacturing schedules.

Typical Release Testing Program

EU Release

All marketed products or investigational medicinal products (IMPs) manufactured outside the EU require re-testing at an EU-based facility. We can provide this service through our local European facilities. Testing programs may include differing combinations of microbial testing, biochemical analysis, purity, safety and potency testing, as required by the regulatory authority for market entry.

Technology Transfer

Controlled management of technology transfer is key to the efficient establishment of an effective lot release program at a contract research organization. Our team initiates discussions with clients regarding their methods at the earliest stages, and carefully studies how their process is actually conducted. This approach allows us to transfer and establish client methods at our facility in the shortest timeline, and maintain control of these methods throughout the life of the product. Our experience with technology transfer, our focus on communication and our rigorous generation of documentation and study performance enables us to support the client in the most effective and timely manner possible.
