AUTOMATED DOWNSTREAM PROCESSING OF A BIOLOGIC PRODUCT
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present application claims benefit of U.S. Provisional Patent Application No. 63/079,860, filed September 17, 2020, the disclosure of which is incorporated by reference herein in its entirety.
FIELD OF THE INVENTION
[0002] The present disclosure provides an automated downstream processing module for processing of a biologic product and methods of using said module. The downstream processing module can process a biologic product from any source, including an automated fully-enclosed upstream production module.
BACKGROUND OF THE INVENTION
[0003] As anticipation builds about accelerated clinical adoption of advanced biologic products such as therapeutic cells, proteins, nucleic acids and other products, more attention is turning to the underlying manufacturing strategies that will allow these products to benefit patients worldwide. While biologic product therapies hold great promise clinically, high manufacturing and processing costs relative to reimbursement present a formidable roadblock to commercialization. Thus, the need for cost effectiveness, process efficiency and product consistency is driving efforts for automation in numerous biologic product therapy fields.
[0004] Automation of various processes is involved in producing biologic products for therapy and various devices and methods have been described, such as in Published U.S. Patent Application No. 2019-0169672 and U.S. Patents 9,701,932 and 9,534,195, which are hereby incorporated by reference. There is a need however for automation of downstream processing of biologic products and integration of biologic product production with automated downstream processing for the isolation or purification of biologic products within a commercial manufacturing platform. The benefits of automation of downstream processing of biologic products include labor time savings associated with using automation as well as improved product consistency, decreased room classification, decreased clean room footprint, decreased training complexities, and improved scale-up and tracking logistics. Furthermore, software can be used to streamline the documentation processes by using automatically generated electronic batch records to provide a history of all processing equipment, reagents, operator identification, in-process sensor data, and so forth.
[0005] An automated, self-contained system in which a biologic product is purified, isolated, and further processed would revolutionize the field of biologic product therapy. There is an urgent need for technology that would allow control of the critical steps of downstream biologic product processing and provide reproducible and stable results, while simultaneously limiting contamination and reducing cost.

[0083] In some embodiments, the method for downstream processing of a biologic product comprises introducing a biologic product into a downstream processing module.
[0084] As referred to herein, the word “introducing” can mean adding the biologic product to one of a plurality of chambers or can indicate the presence of the biologic product within the cassette prior to beginning the method.
[0085] In some embodiments, the method for downstream processing includes sensing and/or adjusting one or more of the following: pressure, temperature, pH, conductivity, UV absorption, and cell density.
[0086] FIG. 6 shows an exemplary block diagram of suitable activities that take place within downstream processing module 108. As shown, in embodiments, an expanded cell product (sample) is first subjected to primary recovery to remove cells from a cell culture broth. Cells are then suitably lysed to expose the biologic product, suitably by mechanical (e.g., beads, shaking, etc.) or chemical means (e.g., lysis buffers, detergents, etc.). A capture step is then used to isolate the biologic product. This isolating is suitably a bind/elute column step in which the biologic product remains in the matrix and impurities flow through. Suitable column conditions and media are known in the art. A retronectin or fibronectin coated surface can also be used. This capture step can be repeated as many times as desired until the total amount of biologic product is collected. This isolation can also include the use of sedimentation columns, as well as chromatography columns and various affinity columns, including sepharose columns that can include functionalized surfaces. Following the initial capture, the pH solution is suitably titrated from about pH 5 up to about pH 7.
[0087] A polishing step is then carried out, for example a membrane polishing step in a flow- through mode, to purify the biologic product. In such a polishing, impurities are absorbed on the membrane and the desired biologic product flows through. An exemplary polishing step utilizes a strong ion exchanger such as a SARTOBIND® Q ion exchanger (SARTORIUS®, Gottingen, Germany). This polishing step removes undesired viruses, DNA, producer cell proteins, leached protein A and endotoxins. Exemplary buffers and conditions for carrying out the polishing step are known in the art.
[0088] Following the polishing, a pH titration and hold step are suitably carried out. This suitably involves dropping pH down to below pH 6 or pH 5, holding for a desired time, and then titrating the pH back up to about pH 7. The processing suitably further includes concentrating or diafiltering the biologic product to achieve the desired concentration.
[0089] Following the concentrating, the biologic product can then be formulated for final product. This can include the addition of various excipients (e.g., salts, buffers, osmolarity adjusting agents), as well as different media, etc. The biologic product is then suitably held at a reduced temperature (e.g. about 4-8 °C) until it can be either administered to a patient, or packaged/shipped or stored.
[0090] In some embodiments, the fully enclosed, downstream processing module receives and/or provides input to a further microprocessing unit. [0091] In some embodiments, the biologic product is produced in a fully enclosed automated process, and can be produced any time prior to introduction into the processing module. The biologic product can be produced and immediately introduced to the downstream production module without delay. In some embodiments, the biologic product can be produced seconds, minutes, hours, days, or weeks before being introduced to the downstream processing module. Suitably, in some embodiments, the biologic product is produced from a batch, a semi-fed batch, a fed-batch, a perfusion or a continuous fermentation process.
[0092] In some embodiments, the biologic product produced is a mammalian cell, or produced within a mammalian cell or any other cell as described herein. In some embodiments, the biologic product is a polypeptide, an antibody, nucleic acid, or any other product as described herein.
[0093] In some embodiments, the method comprises membrane polishing and/or formulating the biologic product as described herein.
[0094] In still further embodiments, provided herein is a method for providing fully integrated automated upstream production and downstream processing of a biologic product.
[0095] Suitably, the method for providing fully integrated automated upstream production and downstream processing of a biologic product utilizes an upstream production module and a downstream processing module as described herein.
[0096] In some embodiments, the method comprises producing a biologic product within an upstream production module, wherein the production module comprises: a cell culture chamber, one or more of a temperature sensor, a pH sensor, a glucose sensor, a lactose sensor, an oxygen sensor, a carbon dioxide sensor, and an optical density sensor, and mechanisms to adjust one or more of a temperature, a pH level, a lactose level, an oxygen level, a carbon dioxide level, and an optical density.
[0097] As illustrated in FIG. 1, suitably manipulation 104 and expansion 106 or the production process, take place within a fully enclosed cell engineering system 102. Suitably, the upstream production module is an automated system. [0098] As referred to herein, “manipulation” can include transduction or transfection, genetic modification with a plasmid or vector, activation, or modulation of culture media conditions to stimulate production of a biologic product.
[0099] In embodiments, the manipulating and expanding of cells described herein take place in a cassette 202 of a fully enclosed production module 102 (see FIG. 2 and FIG. 4). Cassette 202 can include a low temperature chamber, for storage of a cell culture media; a high temperature chamber for carrying out processes involved in producing a biologic product (e.g., transfection, activation, etc.), wherein the high temperature chamber is separated from the low temperature chamber by a thermal barrier, the high temperature chamber including a cell culture chamber; and one or more fluidics pathways connected to the cell culture chamber, wherein the fluidics pathways provide recirculation, removal of waste and homogenous gas exchange and distribution of nutrients to the cell culture chamber without disturbing cells within the cell culture chamber. FIG. 4 shows a flow diagram of elements of a biologic product production process that can be performed in a cassette 202 as described in embodiments herein.
[00100] FIG. 5 shows a flow diagram of various components of a cassette 202. FIG. 5 shows a schematic illustrating the connection between cell culture chamber 510, and satellite volume 530. Also illustrated in FIG. 5 are the positioning of various sensors (e.g., pH sensor 550, dissolved oxygen sensor 551), as well as sampling/sample ports 552 and various valves (control valves 553, bypass check valves 554), as well as one or more fluidic pathways 540, suitably comprising a silicone-based tubing component, connecting the components. As described herein, use of a silicone-based tubing component allows oxygenation through the tubing component to facilitate gas transfer and optimal oxygenation for the cell culture. Also shown in FIG. 5 is the use of one or more hydrophobic filters 555 or hydrophilic filters 556, in the flow path of the cassette, along with pump tube 557 and bag/valve module 558. FIG. 5 also illustrates exemplary positions for input 580, where a biologic product producer cell can be introduced into the cassette 202, as well as output 590, where the expanded cell lines can be withdrawn and transferred to a downstream processing module 108.
[00101] As shown in FIG. 1, following the expansion, the produced biologic product is transferred to downstream processing module 108. As used herein “transferred” suitably refers to the direct connection between the fully enclosed cell engineering system 102 and downstream processing module 108, for example by connecting the output 590 of the system 102 to an input of downstream processing module 108 so as to maintain a closed system and process. As described herein, all of the elements of the automated production and processing method (from manipulation, expansion, isolation to purification) are suitably performed in a closed and automated process. The term “closed” process suitably refers to the use of a cartridge and other contained systems that do not allow for interaction with the external environment (unless desired), with a direct connection to a downstream processing module 108, so as to maintain a sterile process. The “automated” process or “automation” of the process refers to the control of one or more process described herein by an external control, including a microprocessor, to monitor and change one or more of a temperature, a pH level, a glucose level, a lactose level, an oxygen level, a carbon dioxide level, an optical density, a pressure, a conductivity, a UV absorption, or a cell density based on a defined, or pre-set set of circumstances or desired characteristics.
[00102] In embodiments, the closed and automated process is a self-adjusting process, that is one that does not require input from an external (human) user and is able, via various computer programs and conditions, to determine the required modifications to a cell culture or other characteristics to optimize the automated process. In embodiments, the closed and automated process includes monitoring with one or more of a temperature sensor, a pH sensor, a glucose sensor, a lactose sensor, an oxygen sensor, a carbon dioxide sensor, and an optical density sensor. As described herein, the use of these various sensors in the fully enclosed cell engineering system occurs at various times and locations within the system and work together in concert to provide the optimization. For example, the closed and automated process can adjust (e.g., raise or lower) one or more of a temperature, a pH level, a glucose level, a lactose level, an oxygen level, a carbon dioxide level, and an optical density of the biologic product-producing cell culture, based on the monitoring.
[00103] The automated process can also be based on the unique characteristics of the starting cell population that produces or is the biologic product, including for example, the total cell number, the source of the cells, the density of the cells, the age of the cells, etc. These starting cell population characteristics can be input into a computer control system prior to beginning the automated methods, upon which the system will make various initial modifications to optimize the methods, e.g., lactose, oxygen and carbon dioxide concentration, flow rates, incubation times, pH, etc. Alternatively, the monitoring of cell processes enables the automated characterization of the progress of the cell culture sequence from the starting population to enable case-by-case adjustment of conditions for optimized final cell culture properties.
[00104] In further embodiments, the production module recirculates nutrients, waste, released cytokines, and/or dissolved gases during the various method processes. This recirculation helps aid in the production of the desired biologic product. Other mechanisms for optimizing the production of the biologic product include modifying and controlling the flow rate of the media provided to the cells that produce the biologic product. As the cells begin to grow, the circulation rate of the media provided is increased, which improves gas exchange and allows oxygen and carbon dioxide to either enter or leave the cell culture, depending on the conditions of the cells and the requirements at the time.
[00105] In embodiments, the steps of the method are performed in a closed and automated process, and suitably include monitoring with one or more of a temperature sensor, a pH sensor, a glucose sensor, a lactose sensor, an oxygen sensor, a carbon dioxide sensor, and an optical density sensor, and automatically adjusting one or more of a temperature, a pH level, a glucose level, a lactose level, an oxygen level, a carbon dioxide level, and an optical density.
[00106] In embodiments, the method further comprises processing the biologic product within a downstream processing module, wherein the downstream processing module comprises: a housing, one or more units configured to isolate, hold and/or elute the biologic product; one or more sensors and/or mechanisms to detect and/or adjust one or more of the following parameters: pressure, temperature, pH, conductivity, UV absorption, and cell density; and a fluid containment system in fluid communication with said units, sensors and/or mechanisms, wherein each of the steps of the downstream processing method that occurs in the downstream processing module are contained in the housing.
[00107] In exemplary embodiments, the method comprises the upstream production module in fluid communication with the downstream processing module. [00108] In further embodiments, the unit configured to isolate, hold and/or elute the biologic product comprises one or more of the following: a chromatography column; a chromatography filter; a concentration and/or buffer exchange unit; a primary recovery filter; a pH sensor; and a pH adjustment mechanism. Suitably, in some embodiments, the unit comprises a disposable unit. In some embodiments, the disposable unit is a cassette.
[00109] In some embodiments, the disposable unit and/or cassette are: a chromatography column; a chromatography filter; a concentration and/or buffer exchange unit; a primary recovery filter; a pH sensor; and a pH adjustment mechanism.
[00110] In further embodiments, the production and/or processing module receives and/or provides input to a further microprocessing unit.
[00111] In still further embodiments, the biologic product is produced from a batch, a semi-fed batch, a fed-batch, a perfusion and/or a continuous fermentation process.
[00112] In some embodiments, the biologic product produced is a mammalian cell, or produced within a mammalian cell or any other cell as described herein. In some embodiments, the biologic product is a polypeptide, an antibody, nucleic acid or any other product as described herein.
[00113] In some embodiments, the method comprises membrane polishing and/or formulating the biologic product as described herein.
