  • Products in current clinical pipelines are much more specific to patient and disease. Many companies are further stratifying their products by coupling it with a clinical diagnostics which in turn makes the product oriented to a specific patient sub-groups and is of higher value. Time to clinic and time to market is critical in order to maximize the financial gain for the particular product. Also patients depend on these critical products. Many of the products that are in the clinical pipeline tend to be point at the filling stage requiring containment of the product. Because the products are being produced at smaller volumes building leaner, modular and simpler facilities minimize the invested capital required to bring these products to market. Superior fill-finish flexibility allows the company to make a single fill line investment with the ability to manufacture multiple products irrespective of the format, product or dosing requirements.
  • Here is an chart that illustrates the various process involved in aseptically filling products in various formats on traditional dedicated fill lines. Each container format has a specific process and hence a specific machine for the given container. Before moving on, let’s take notice that there are several process commonalities between the formats. Vials and cartridges require a stopper and a cap, cartridges and syringes both have pistons inserted post filling
  • As illustrated on the previous slide traditional aseptic manufacturing is a dedicated process that is specific to the container format. You can’t make a traditional vial “mono-bloc” style filler fill and insert a piston into a syringe. The ability to add additional filling capabilities to a facility once you are fully invested in fill line for a particular container can be costly, have a long lead schedule and can be disruptive to current manufacturing operations. Suffice it to say, to be able to fill additional formats with traditional aseptic fill lines is a significant time and capital investment. Traditional fill lines especially for those handling non-nested containers can have some processing challenges like glass on glass contact, machine jams and broken or fallen containers to name a few. Traditional fill lines are very efficient for filling products and containers that do not require flexibility.
  • Flexible aseptic processing is an alternative approach, which leverages the commonalities between the various container fill-finish processes but using a single manufacturing platform. This is done by integrating industry leading technologies such as single-use disposables, isolator barrier technology, automation and robotics, and lastly ready-to-fill nested formats. Simplifies the manufacturing process by eliminating the container preparation process at the manufacturing site. The end result is a manufacturing process that has the flexibility to fill multiple container formats and sizes on a single modular platform. Some of the other key benefits derived from this is the ability to standardize the facility for not only your current manufacturing site, but you are able to transplant the same floor plan elsewhere globally because the equipment remains the same. Facility floor space and utilities required for the operation are also reduced. Lastly and more importantly a flexible asset can be utilized irrespective of the container to be processed.
  • Options are available for all formats to be supplied in ready-to-fill configurations just like BD has done for years with the Hypak syringe. Ompi’s EZ-Fill nested vials and cartridges have the same presentation as nested syringes having a nest which holds and locates the vial within the tub. A tyvek lid and liner seal the containers within the tub.
