MSR™ MicroSphere Refiner - Advancing Aseptic Processing for Polymeric Microspheres

The MSR™ MicroSphere Refiner, acGMP piece of equipment was designed by PSL to provide drug manufacturers with an all-in-one, innovative solutionto carry out a variety of aseptic procedures at different scales with their microspheres. Polymeric microspheres are complex injectable drugs that provide sustained and controlled release of the drug load into a patients body, offering patient well-being and superior treatment adherence than usual delivery methods.

The MSR™ helps overcome the challenges of polymeric microsphere processingsuch as filtration and drying inefficiencies, poor batch reproducibility, and lack of sterility assurance.

PSL analyzed systemic industry difficulties and gained a deeper understanding of microsphere processes with end users in the field. Using a Quality-by-Design (QbD) methodology, focusing on the properties and process behavior of polymeric microspheres, pioneeringMSR™ technology can now be used to conquer the challenges in microsphere scale-up development.

Features and Benefits

An All-in-One Solution

Drug producers can use the MSR™ MicroSphere Refiner, a piece of Current Good Manufacturing Practice (cGMP) equipment, to finish various aseptic operations with their microspheres at different scales.

Because it can perform the following tasks in a single system, it naturally maximizes product recovery, batch repeatability, and production flexibility:

Classification, filtration, and dewatering of microspheres

Washing microspheres

Drying microspheres, including freeze-drying

Microsphere discharge and recovery

Batch Reproducibility – At the Touch of a Button

The MSR™ MicroSphere Refiner is a completely automated device that eliminates the need for manual handling of products during the production process. This minimizes the possibility of human error while optimizing batch-to-batch reproducibility.

At the push of a button, production can begin, and pre-planned process recipes can be followed.

Thanks to the PSL automation and configurator platform, drug producers can pre-design and pre-load software process recipes with the necessary process parameters appropriate for their particular production needs. This increases the speed and adaptability of their production operations.

PSL can comply with major international software automation practices and regulations, such as GAMP5 (Good Automated Manufacturing Practice, version 5 by ISPE) and 21 CFR Part 11, developed by the US FDA for electronic records and signatures.

Product Recovery – A Crucial Requirement

Because microspheres are an extremely expensive element in the development and production of drugs, pharmaceutical companies must maximize product recovery to maintain their competitiveness worldwide. This essential requirement was considered when designing the core elements of MSR™ technology.

The MSR™ MicroSphere Refiner's product recovery process is unique since it is automated and eliminates the need for operators to manually offload products through an aseptic isolator, for example.It helps maximize product yield by minimizing the number of transfers and connections.

Production Agility, Delivered

The MSR™MicroSpehere Refiner is suited to many product applications. It is designed to enable companies to maintain their agility and quickly adjust to shifting production needs.

Process, PAT-Verified

The US FDA promotes using Process Analytical Technology (PAT) in the pharmaceutical sector to ensure improved product quality control and a faster time to market.

Drug makers have welcomed the PAT approach because MSR™ technology enables them to monitor their microsphere product quality and integrity in real-time during several production phases, including filtration and drying processes (including lyophilization).

The trial-and-error approach is reduced with the inclusion of PAT. This helps shorten the time it takes for pharmaceutical companies to develop drugs for microspheres, typically more complex than conventional drugs, and helps them progress toward right-first-time manufacturing.

Successful Scale-up

For most drug producers, large or small, developing sophisticated drug formulations such as microsphere delivery systems has always been difficult. It is essential to ensure that the process technology selected for the R&D stage can be fully scaled to bigger production batches.

Drug makers may have to pay millions if they discover too late that a microsphere method is not scalable.

The MSR™ scale-up approach was created to make developing microsphere pharmaceuticals more straightforward, starting from the preliminary R&D stages and moving through GLP batches, clinical trials, and finally commercial production.

The solutions can guarantee that important production factors like filtration time, washing time, drying time, etc., as well as important process objectives like product yield, product quality and integrity, batch uniformity, etc., can be maintained at each scale.
