In-Process and Release Tests at Althea

Althea gives you access to a broad range of technologies for on-site release and in-process testing as well as stability studies for drug substances, developmental formulations and clinical trial products. On-site efficiencies provide you with time saving performance that is critical to IND, IMPD and early-phase clinical studies.

Both our Quality Assurance group and Analytics teams work together to execute the highest quality release tests and deliver you the data you need for clinical trial approval process. Our analytical scientists design, implement, and manage stability studies that are appropriate for your specific product and stage of clinical testing.

ICH compliant protocols are used to monitor the stability and release readiness of your product. The Althea analytical team is in direct communication with your clinical development team consistently sharing data, coordinating schedules, and planning upcoming tests.
