Biowaived Ltd. is officially open for business with the announcement that our laboratory in Sandwich, UK, is operational and prepared to assist clients with their dissolution and biopharmaceutics workflows. Our team of experienced analysts, now equipped with an inventory of qualified laboratory instruments, is prepared to fulfil client requirements with an unwavering dedication to quality of service. We offer a comprehensive range of testing and analytical services, giving clients confidence in their biopharmaceutics risk management, dissolution strategy, and formulation performance. We can help de-risk drug product performance ahead of clinical studies, support biowaiver applications by designing and delivering the required dissolution and solubility work packages and much more.

API Properties
Assessment of a drug product performance starts with understanding the physicochemical properties of the active compound. Knowledge of the compound should be implemented in the design of the formulation and considered when designing in vitro test methods. With our new laboratory set up, we are offering a range of solubilty testing services including pH profiling, ICH M9 solubility studies for BCS-based biowaivers, solubility in biorelevant media, solubility in drug product vehicles, and solubility of amorphous materials. We also offer API physicochemical profiling such as pKa, LogP, Ksp, stability, bile partitioning and intrinsic dissolution rate (IDR).
Dissolution
Our dissolution capabilities extend to USPI (Basket), II (Paddle), III (Reciprocating Cylinder), and IV (Flow-Through Cell) apparatus for use with a range of different dosage forms and methodologies designed to assess in vitro product performance and support drug product development. In addition to standard or compendial dissolution tests we offer biorelevant dissolution studies to provide in vitro data which factors in the critical dissolution attributes affecting drug product performance in vivo enabling correlations to be made between them. If you need assistance with dissolution, our team has extensive experience with analytical method development and validation. With access to HPLC, UPLC, and online-UV technologies, we can design and validate your methods with ultra-fast run times for quick data generation and processing.
Supersaturation & Precipitation
Precipitation in vivo can pose a significant biopharmaceutical risk for basic and acidic compounds. From precipitation of an acidic compound administered as a liquid in the gastric environment to precipitation of basic API upon transition from gastric to intestinal environment, these processes can jeopardize drug product performance and lead to low bioavailability. Several techniques are available in the Biowaived laboratory for the assessment of supersaturation and precipitation. We possess the instrumentation and expertise to adapt dissolution methods to more closely mimic critical in vivo attributes. Two-stage dissolution transfer, biphasic dissolution methodologies and an artificial stomach duodenum (ASD) enable the assessment of supersaturation and precipitation under biorelevant conditions.
PBBM/PBPK & Dissolution Modelling
The in vitro data generated in laboratory must be interpreted and contextualised to aid biopharmaceutical risk assessment. In silico methods are helpful in supporting analytical method development and forecasting drug product performance based on experimental data. We are using Siemens gPROMS Formulated Products as part of dissolution workflows and to optimise dissolution conditions during method development. PBPK modelling is also possible using a range of simulated in vivo conditions, assisting with risk reduction and formulation selection.
