Although the realization and use of various embodiments of the present invention are discussed in detail below, it should be considered that the present invention provides many applicable inventive concepts that can be incorporated in a wide variety of specific contexts. The specific modalities discussed here are only illustrative of the specific ways to carry out and use the invention and do not limit the scope of the invention.
To facilitate the understanding of this invention, some terms are defined below. The terms defined here have meanings as commonly understood by those of ordinary knowledge in the areas pertinent to the present invention. Terms such as "one", "one" and "o" are not intended to refer to just one entity in the singular, but include the general class of which a specific example can be used for illustration. The present terminology is used to describe specific embodiments of the invention, but its use does not limit the invention except as outlined in the claims.
The present invention includes a modular pharmaceutical facility for the production, for example, of vaccines and includes all necessary quality control, quality assurance, and batch release functions. The final product can be made within the same module or in an adjacent module filled with vaccine in bulk vials, suitable for distribution, and in accordance with all current FDA Good Manufacturing Practice (cGMP) guidelines. The following terms are used interchangeably "modular unit", "structure", "unit" or "module" to describe a unitary structure that includes at least a portion that is a sealable work area or clean room in which one or more functions or processes are conducted that require a controlled work environment and a mechanical service room or area (which can be closed or opened) and which supports the clean room and provides redundant services for the clean room, for example air, electrical, water, wastewater, water removal, chilled and / or heated water, gas, control units and sensors, security. These services will generally be connected to a service source that uses universal connectors, which are those commonly used as connections in the industry (for example, 110 or 220 volt connections, h-1 inch liquid or gas connections, wired connections or wireless for intranet, extranet or Internet and the like).
As used herein, the terms "validation" and "pre-validation" are intended to cover all documented processes or actions performed to demonstrate that a procedure, process or activity will consistently produce an expected result. Validation typically includes qualifying equipment and systems. Validation is an essential component required of Good Manufacturing Practices (GMP) and other requirements of regulatory bodies. For example, in the validation of a pharmaceutical industry installation, the process is carried out before obtaining approval from the regulatory agency for the manufacture and commercial sale of the pharmaceutical product. Validation activities in the pharmaceutical industry may also include experimental tests (pre-validation) before carrying out effective validation to establish validation limits, crucial manufacturing controls, alert limits, etc. to assess the potential outcome of the effective validation course. Validations routinely performed on cleaning validations, process validation, analytical method validation, computer system validation, qualification systems and equipment including: project qualification (DQ), component quality (CQ), installation quality (IQ ), operational qualification (OQ), and process qualification (PQ).
Those skilled in the art will recognize that although the structures, facilities or units described in the present invention are validable, they may not be validated or validated for certain uses and applications, particularly for non-human use or the manufacture of products for non-human consumption ( for example, veterinary applications, agricultural applications, pesticide manufacturing, etc.).
Each modular unit, whether operating alone, in a group or as part of a multimodular unit installation, can include specific enclosed spaces for the manufacture, fermentation, development (for example, in a bioreactor) of the composition requiring an approved GMP or cGMP installation by PDA which includes, for example, GMP controlled areas, lights, consistent with USADA, CDC, PDA or standards for foreign equivalents, including clean room conditions, purification, chromatography, filling in bulk or individual bottles, which can be arranged, for example, inside a factory or standard installation with a sufficiently high free space to accommodate units within it. In one example, modular units can be placed within a building envelope that includes standard electrical connections, water, wastewater, air handling to which the units are connected. The present invention does not require pre-assembly or reassembly of the multiple units since each can function independently and can be used for multiple purposes.
For example, a complete manufacturing facility can be built, within hours to days, from pre-assembled, pre-approved modular units that include all the necessary equipment for the desired function (s) for that unit within the facility manufacturing. These modular GMP modular units by design allow for the design of multiple installations for quick installation and reinstallation of units based on project needs. For example, a modular unit may include an independent bioreactor, the necessary liquid handling devices, refrigerators, tissue culture hoods and microbiology test equipment, basic laboratory equipment (pipettes, sterile pipette tips, development media, Petri dishes, incubators, and other general laboratory supplies), which have been tested and pre-validated to comply with cGMPs or other requirements in accordance with the regulatory body or in accordance with applicable codes, statutes, regulations, standards or equivalent. A modular unit for protein isolation, adjacent, but completely independent of the bioreactor unit, can be positioned and in communication with the bioreactor unit in such a way that the materials manufactured in the bioreactor are quickly and easily transferred to the protein isolation unit which has pre-approved and validated protein separation units, for example, centrifuges, liquid chromatography columns, spectrophotometers, polyacrylamide gel electrophoresis (PAGE) units and bulk packaging units. The bulk protein can then be transmitted to a packaging unit that includes all the equipment needed to fill individual doses of the protein, small molecules or other agent being manufactured.
In addition, the use of individual molecules provides rapid exchange and continuous product manufacture in the event that part of the manufacturing process must be changed or revalidated (for example, in the case of the manufacture of different biological substances or detection of contamination) without the need to re-certify the entire installation. The addition of more modular units also allows for very rapid expansion that can be customized for short periods of time. For example, a facility may receive the addition of modular units for expansion for a short period of time and the isolation of a vaccine for a short period of time and the reinstallation of those units elsewhere after the end of the production course. In fact, the present invention can be used in existing manufacturing facilities for short-term expansion of manufacturing capacity without the need to revalidate new manufacturing capacity or costly long-term installation of an additional production line that will only be used by a short time.
The modular units of the present invention can be used as independent installations (provided that include all the equipment necessary to manufacture, insulate and package) or they can be placed within an existing structure. An example of such a structure is an empty factory or building. Such a structure could be of standard construction, precast concrete, flat slab with smooth flat floors, inclined concrete wall, double T shaped precast ceiling and having steel or other walls (which can also be lined with epoxy for cleaning ability). Inside the building, the modular units provide the exclusive wet laboratory, bioprocess development and purification units needed for manufacturing. These units are simply lifted into position (for example, pushed on aerostatic bearings, pulleys, pallets), connected to a power source and, if necessary, a supply of water and / or waste water.
The present invention allows the designer to connect a modular unit in operation to one or more additional modules in operation without deranging the function or compatibility of the original modular unit (s). In addition, the designer also has the ability to disconnect a functioning module from one or more additional functioning modules without deranging the function or compatibility of the original modular unit (s).
Yet another design option for the modular units of the present invention is the addition of an efficient energy recovery system that allows for energy recapture at a much higher rate than can be expected with existing methods. In this modality, the modular unit can also be connected to the central HVAC system of the building that houses the modular units. The intake and exhaust of the redundant HVAC systems of the modular units can be connected to the central HVAC of the building in this way improving the energy efficiency of both units. For example, the modular units of the present invention can be placed inside a second environment (a building with room temperature or less humidity), which has the modular unit interacting dynamically with that second environment. In this form of operation, the modular unit can use ambient air that does not need to be treated by a large and expensive external air handling unit.
Another major improvement over existing projects is the ability of modular units to serve multiple customers with a single group of modular units. For example, a biotechnology research park or similar business facility could host several different companies, each having its own production facility or modular unit. A distinct advantage of using modular units is that each completely independent modular unit can contain scrap, spills, hazardous, individual, etc., without affecting any other structures (within a process flow or affecting an adjacent production facility, for example , when an installation has several production lines or different companies).
When the modular unit needs to be connected to a water source, the incoming water could be purified in an adjacent modular unit that could serve several different production lines or the module itself could include a water purification unit. The modular unit of the present invention has the advantage that redundant air handling units, electrical panels and even water filtration units can be in the portion of the modular unit that is adjacent to the clean room and can be serviced without service has to enter the clean room area. When handling wastewater, the modular unit can include sink pumps to eliminate waste. In addition, the inlet bag / outlet bag filters connected to the air handling inlets can also be changed without the need to enter the clean room area. These externally accessible portions of buildings, or compartments, allow maintenance personnel to service the unit without the need to dress and enter the clean room area.
Duplicate processes and equipment for handling air, exhaust, etc. with fault tolerance / automatic switching allows the user, for example, from an external panel or via the Internet, to switch from a first system to a second system if the sensors inside the modular unit detect a problem with a component in the first system or as part of regular maintenance.
Another feature of the modular units of the present invention is the ability to use connection devices that are well known to maintenance personnel.
For example, modular units can use standard fast-acting connectors for chilled water, electricity, etc. that allow the user to switch the modular units externally into operation. An advantage of the present invention is that it can take advantage of the existing building infrastructure, for example, mechanical equipment such as boilers, clean steam generator and compressors that can be easily connected to the units. The building's existing maintenance facilities and staff serve to maintain cGMP services and equipment and environmental service compatibility from outside the modular unit.
The present invention also includes a comprehensive management system that provides for monitoring and maintaining the module including electricity, water, fire, security, video, etc. externally.
The modular units of the present invention can be made, for example, from a welded aluminum frame, with an aluminum wall structure of materials and coatings that can be cleaned in the drug production environment, in accordance with cGMPs as described by USED, CDC, FDA or equivalent regulatory agency. Stainless steel installations and surfaces can also be used when needed, but could increase the weight of the unit if there is a weight limit. The HVAC system can divide the set into four zones: a service corridor that will be an unclassified controlled space, dressing rooms and undressing rooms that will be classified as Class 10,000 (ISO 7) and a processing area that can be classified as in
Class 10, 100, 1,000, 10,000 or higher depending on the requirement. Within the modular unit, the appropriate pressure cascade of at least 0.035 inches of water column is created by adjusting the inlet and exhaust fan outlets and adjusting the return air volume in each space. For example, pressure changes are usually made between the process area and the dressing rooms, and dressing rooms up to the corridor. Outgoing air filtration will be provided by a "in bag / out bag" HEPA or ULPA filtration module. The incoming air will be pre-filtered with a series of filters applied integral with the air handler, which can be exchanged externally from the clean room. The floors can be, for example, monolithic epoxy, and the ceilings can use 2x4 non-detaching roof tiles in conjunction with the indispensable fan-driven HEPA filters.
The environment of the modular unit, for example, within the clean room portion of the modular unit or even the maintenance portion of the modular unit, can be controlled and monitored externally using standard network information and remote system monitoring systems. All instrumentation and process equipment, where appropriate, will also have data interfaces installed on site and remote data collection and will be addressable via Internet protocol (IP).
The modular units will be equipped to easily interface with services such as individual electrical connections, chilled water supply, external supply of gas, compressed air and liquid nitrogen if necessary for the process. In addition, modular units can be equipped with aerostatic bearings, so that modular units can be easily moved to other areas to be reconfigured in near real time to support the required processes and swing capabilities without disturbing ongoing operations.
Each modular unit can be pre-assembled with a final documentation package that can include: the design, structural, mechanical, electrical and plumbing drawings, system dossiers, installation qualification and operational qualification plan and executed documents, maintenance records , and pro-forma quality assurance documents including basic standard operating procedures. These can be provided in hard copy, or provided via a display panel inside the modular unit or externally (including inside the maintenance compartment) which is electronic and can include the necessary access code / password protection. In reality, the entire unit may include security features such as access code / password protection to enter the clean room and / or maintenance compartment, systems within the clean room (for example, all equipment within the room, for example , bioreactors, columns, centrifuges, computers, assembly lines, input / output lines (liquid, solid, gas), electronic connections (including wired and wireless connections), data storage medium, liquid storage medium and samples , storage of controlled substances (including safes or storage cages), incubators, refrigerators or freezers, -70 ° or other low-temperature storage medium and entry or access to laboratory equipment and supplies.
GENERAL: The redundant HVAC system can include two or more 100% redundant air systems, each having an air handler with exhaust air damper, exhaust fan with exhaust air damper, and / or a duct heater electric. In operation, the HVAC system can include: a Building Automation System (BAS) that can start / stop the HVAC equipment (and others) electronically or mechanically. An air system that can be "ON" continuously (for example, having instant automatic switching between systems, including an "unoccupied" mode operating continuously). Advance and delay systems can be switched based on need, for example, weekly or monthly. The air system can include one or more dampers, limit switches; air damper and exhaust system exhaust fan delay controllers; fan discharge switches; valve control and even duct heater controls.
AIR SUPPLY FAN CONTROL: Constant speed air supply fans can be operated from inside the clean room, remote automatic start / stop switches, and / or a Building Automation System (BAS) to monitor , for example, the status of the ventilator. If the forward air supply fan stops for any reason, the forward air system will be stopped according to the air system stop command and, optionally, an audible, visual and / or silent alarm.
TEMPERATURE CONTROL: The temperature in the unit can be controlled by means of the air handling unit and / or a chilled water valve (CHW) that modulates the control coil leaving the air temperature and / or the temperature control in the clean room, dressing room or undressing room and / or maintenance room. The system also includes a duct heater that can be modular to control the temperature of the space.
EXHAUST FAN CONTROL: Constant speed exhaust fans will be capable of remote automatic start / stop and can be monitored via BAS, which monitors the status of the fan. If the fan (s) stops for any reason, the air handling system will be stopped, and an alarm will be sent to BAS and the redundant unit will immediately start operating.
CONTROL OF COLD WATER SYSTEM: The chilled water system will be capable of remote automatic start / stop. The chilled water system will be enabled whenever the incoming air temperature of the air handling unit (AHU) is above the determined temperature of the chilled water coil discharge air. From a system start command, the CHW pump will be activated and the chiller controls will be enabled; the chiller will be activated when flow is provided. From a system stop command, the chiller will be disabled, and the pump will continue to run for 5 minutes and then stop. BAS will monitor the status of the pump. If the pump fails, the chiller will be disabled, and an alarm will be sent to BAS. BAS will monitor the status of the chiller and can provide instant automatic switching capability by automatically switching to a redundant chiller. If the chiller fails, the pump will be stopped 5 minutes later, and the alarm will be sent by BAS.
ADDITIONAL MONITORING POINTS AND SYSTEM ALARMS: The pressure of the space can be monitored, for example, the pressure in the clean room. If the pressure drops to 0.0 inches of water column (WC) or below, an alarm can be sent to BAS. Several pressure sensors mounted on the modular unit (for example, one in the corridor, one in each of the dressing rooms and one in the main laboratory area of the modular unit) can be provided and monitored. When an alarm is sent to BAS, the system can call pre-programmed emergency phone numbers and / or communicate electronically via text or email.
Additional points that can be monitored on the modular unit include, for example, a static pressure exhaust sensor in communication with the air handling units (AHUs). For example, BAS can determine if there is a belt failure whether in the HAUs or EFs by using, for example, an amperage sensor that monitors the change in ampere consumption in the engine. Another sensor can be a Pitot tube in the supply air duct and exhaust air duct that monitors the static pressure connected to the BAS. In addition, gravity dampers, automatic dampers and damper end switches and controls can also be connected to and monitored by BAS.
Figure 1 shows a modular unit 10 of the present invention. The modular units of the present invention can be made, for example, from a welded aluminum frame, with an aluminum wall structure complete with materials and coatings that can be cleaned in the drug production environment and are in accordance with cGMPs as described by the USDA, CDC, FDA or equivalent regulatory agency. The modular unit 10 includes two parts, a clean room 12 and a maintenance room 14. The clean room 10 includes a dressing room 16, which in this example provides the only entry point 18 for clean room 12, and a room to strip off 20. In this configuration, the clean room 12 includes a -80 ° C freezer 22, an incubator 24, a biosafety cabinet 26 and cabinet 28, which are pre-installed in this clean room configuration 12. The freezer -80 ° C 22, an incubator 24, a biosafety cabinet 26 and cabinet 28 can be fixed to the walls and floor using pre-installed fixing points that can be positioned throughout the interior of the clean room 12, or can be installed under measure. The maintenance room 14 is separated from the clean room 12 by a wall 30 that isolates the clean room 12 from the maintenance room 14. The maintenance room 14 has a single entry point 32, through which maintenance personnel can attend to portions of physical installation of the modular unit 10 without having to access the clean room 12. All wiring, plumbing and air ducts of the modular unit (not shown), are pre-installed on the walls of the modular unit and are sealed in such a way that the clean room 12 is isolated from the environment around clean room 12. A redundant HVAC system 34 is found in maintenance room 14 and may include an inlet / outlet bag filtration system 36. Electrical box 38 is found inside maintenance room 14 and may include not only an electrical panel / breaker box for modular unit 10, but may also include wired and / or wireless communication equipment. In this example, the return air ducts 40 are positioned on the floor of the clean room and are returned via a sealed duct to the HVAC 34 system.
In the configuration illustrated in Figure 2, two modular units 10 are shown and can be connected via a service corridor 50, which can be a controlled space, dressing room and undressing room that will be classified as Class 10,000 (ISO 7 ) and a processing area that can be classified into Class 10, 100, 1,000, 10,000 or higher depending on the requirement.
Figure 3 shows two modular units 10, with service aisle 50 and details of an air duct and filtration system connected to air handling units 60. Within the modular unit 10, the appropriate pressure cascade of at least 0.035 inches of water column is created inside the ducts 60 through the use of changes in the size of the duct and / or deflectors and return ducts 66. For example, pressure changes are usually made between the pressure area and the dressing room 16, and the strip room 20 for corridor 50. Exit filtration will be provided by HEPA or ULPA filtration of "inlet bag / outlet bag", and HEPA 62 filters, which alternate with lighting accessories 64. The Incoming air can be pre-filtered with a series of plicated filters integral with the air handling system 24, which can be exchanged externally from the clean room 12. The filters can be, for example, monolithic epoxy, and ceilings can use 2x4 ceiling tiles without detachment in conjunction with indispensable fan-driven HEPA filters. Figure 4 shows a side view in which the ducts 60 are shown in relation to the return ducts 66.
The present invention includes one or more of the following sensors and, optionally, electronic reporting units that inform, in real time or based on a predetermined or programmable program, in which the sensors can inform the status of the various areas or systems of the modular units , including: room temperature (degrees C or F); relative humidity of the room; four pressure sensors (for example, 1 in the hall, 1 in the dressing area, 1 in the undressing area, 1 in the laboratory / clean room); ambient air temperature (degrees C or F); ambient relative humidity; HEPA filter life cycle status (for example, measured in inches); chilled water temperature (degrees C or F); chilled water pressure (psi); air supply fan status (2 each); exhaust fan status (2 each); chilled water status (degrees C or F); chilled water supply and return temperature (degrees C or F); status of the chilled water pump or various sensors to read the status and performance in: temperature, CO2, air flow, on / off, security, door position, entry and exit of personnel, inventory control.
Strengthened for harsh environments: The structure and portability of clean rooms provides use as a strengthened facility for harsh environments. As previously described here the clean room can be used as a standalone unit or can be combined with other modules that serve as support units, such as a unit to contain cooling equipment, and / or a unit to contain mechanical equipment (such as a set of generators, a compressor, and / or water containment and / or purification equipment). Such a clean room or set of clean rooms can be transported to an area by various means, such as air force C17 transport, truck, or boat with the intention of quickly setting up a clean room installation in an area other than has infrastructure for that. Such an assembly could be quickly dismantled and removed.
Hospital / Surgical / Screening: The structure, portability, and controlled environment of the clean rooms provide use as a hospital unit or units, surgical set or sets, and / or screening facilities for areas where infrastructure is not otherwise available. such facilities or in areas where such facilities have recently been destroyed, or in areas where additional facilities are required before one can be built. The controllability of the indoor environment and the ability to create a Class 100 or Class 1,000 compliant environment would be suitable for a burn unit, where all patients are at risk of infection from exposure to airborne microbes.
Compactly portable: The units described here are compact enough to be transported in a variety of ways, including, but not limited to, highways, train, sea, and air. The units can be placed in a flat-bodied trailer pulled by a semi-trailer, sealed in transport containers for rail or sea transport, or placed in an air transport plane, such as a Boeing C-17 Globemaster military transport plane III. The units are designed and built to withstand the physical effort of displacement by road, train, sea, and air and have such a weight as to be portable through these means of transport. The units of the present invention can also be constructed with structural lifting points and lifted by means of hydraulic lifters inserted at these points to be lifted up slightly above the level of a flat body trailer. The flat body trailer is then moved back under the unit and lowered and secured for transport.
Designed for maximum cleaning capacity: As cleaning capacity is crucial for the aseptic environment provided by clean rooms, floors, windows, and walls, they are made in such a way as to reduce, if not completely eliminate, cracks, crevices, joining spaces and others. areas where dust and microbes can settle or accumulate. The windows are flush mounted inside to reduce the small areas in which dust and microbes can accumulate and to increase the ease of cleaning of the joint in which a window meets a wall. The floors are covered with a monolithic application of an epoxy resin. The walls are similarly covered with a monolithic application of epoxy resin. This creates increased cleaning capacity of both the wall and the floor surfaces, but more importantly, it reduces the number of joints and cracks within the wall and floor surfaces as well as eliminating a joint and / or crack where the wall meets the floor.
Clean rooms are built in multiple dimensions, including 12 feet by 43 feet, 15 feet by 43 feet, and 18 feet by 43 feet. The height can be from 10 feet up to 18 feet. Lengths can be adjusted as required below 43 feet. These dimensions allow ultimate flexibility in use in transportation. The 12-foot-wide units are more applicable for air and sea transport, while road transport allows for up to 18 feet in width. The height can be increased to 18 feet to allow for the installation of larger equipment, such as large bioreactors that require such superior space.
The clean rooms of the present invention can be made with monolithic epoxy walls and floors. This provides a very resistant surface that can be properly cleaned for use in Level 3 Biological Safety (BSL3) and Level 3 Animal Biosafety (ABSL3). The clean rooms can be operated in a completely isolated negative pressure mode and then connected to a modular clean corridor. This fact provides at least three levels of air cascade essential in BSL3 applications. A new approach was also designed by the present inventors for the ABSL3 installation that uses the cleanroom portability for maximum advantage and a new paradigm. The project is illustrated in Figure 5. The concept is that the animals remain in one place and that the services and procedures are brought to them through mobile clean rooms. The outer row of clean rooms represents areas for animals being treated in separate studies.
Services such as providing food and removing waste can be facilitated through mobile cleanrooms. Experimental support services such as imaging, surgery, necropsy and others can be taken to the individual animal containment area. Animals can be transferred in confinement to the required service and returned if applicable to their habitat clean rooms. This approach allows for higher confinement for these processes since the animals will not be transported throughout a building to different laboratories for sophisticated treatment or diagnosis and other procedures. Containment is facilitated by a coupling system that provides a confined passage for animals. The pressure can be maintained negatively for both clean rooms in relation to the gray space. Both clean rooms are isolated from the gray space by filtering both inlet and exhaust air.
The clean rooms can be used as manufacturing or medical facilities for the military and others because it is built for air transport on cargo planes such as a C-17 military transport. Factories configured by multiple modules can be transported and quickly enabled with independent chilled water, energy and steam service modules. Other intended uses are for medical and surgical treatment sets in remote areas.
Filling of antigens at the site of a bioterrorism or biological "hot zone": A clean mobile unit can be designed with a sterile filling machine to fill injector tips that are used for pneumatically driven injection. This indicates that a clean room could be transported by air to an event location where bulk pharmaceutical substance could be delivered directly from the manufacturer to the location in bulk filled containers containing hundreds or thousands of doses, for example, 250 ml and 1 mg per ml producing 2,500 doses in 100 micrograms per dose in a dose size of 0.1 ml. The fact that the bulk material could be delivered to the site without the need for filling in individual doses. This could save weeks on delivery to a "hot zone" since an intermediate filling step would not have to be performed.
A specially designed chamber will allow the transfer of waste from the clean room to a sealed portable container for transporting solid and liquid waste from a process. This container is portable and fits with an exclusive passage for the transfer of waste materials. The outer door of the passage is then closed followed by the inner door in the clean room and the transfer is completed.
The clean rooms of the present invention have been included in a new concept involving up to six different processes for manufacturing biotherapeutic media that can be done in the same gray space infrastructure as illustrated in Figure 6. Due to the confinement and flexibility, multiple processes can be implemented and changed without disrupting other depositaries in space.
Modular clean rooms are being used for processing the downstream portion in biology or in a very large commercial vaccine facility. Eight clean rooms are used for downstream processing including tangential flow filtration, chromatography, sterile filling, buffer preparation, equipment washing and quality control testing.
