Definitions
- the invention relates to a method for inactivating viruses in a fluid according to the preamble of claim 1, a method for incubating a fluid according to the preamble of claim 8 and an incubation device for incubating a fluid according to the preamble of claim 9.
- Inactivation of viruses is required, for example, in processes in which active viruses are contained in certain biopharmaceutical products, such as protein solutions.
- the viruses can be added to the process during production from an external source, for example from starting materials used for fermentation, or from internal sources, for example from the cell line used for the process. By inactivating the viruses, subsequent infection of patients through potential viral contamination in the product can be reliably prevented.
- a starting fluid contaminated with active viruses is first mixed in a mixing arrangement with a virus-inactivating reagent to form a reactive fluid.
- Mixing involves adding the reagent to the starting fluid and at least partially homogenizing it.
- Possible reagents include agents that lower or raise the pH value of the fluid so that the viruses are inactivated in an acidic or basic environment, for example through an oxidation reaction.
- alternative virus-inactivating agents and chemicals that cause corresponding inactivation can also be used as reagents.
- the active viruses are inactivated by incubating the reactive fluid.
- the reactive fluid is incubated for a required time so that a certain proportion of the initially active viruses are inactivated. It is usually not necessary to inactivate all active viruses, but only a certain proportion of active viruses.
- the inactivation of the viruses in the reactive fluid is stopped. This is done by mixing the reactive fluid with another reagent or by removing the virus-inactivating reagent from the reactive fluid.
- the pH value is increased or decreased again by mixing the reactive fluid with another reagent.
- the reagent is previously mixed with an alternative virus-inactivating agent or an alternative virus-activating chemical as a reagent, however, this is removed from the reactive fluid. By mixing with another reagent or by removing the reagent contained, the reactive fluid becomes a resulting fluid.
- the known prior art (US 2013/0260419 A1), from which the invention is based, relates to such a method.
- a fluid contaminated with active viruses is mixed with a pH-lowering reagent in a mixing arrangement comprising several mixers and incubated in the mixing arrangement, whereby the active viruses are inactivated over time.
- the inactivation is then stopped by mixing the fluid with another pH-increasing reagent and the resulting fluid is thereby produced.
- the invention is therefore based on the problem of designing and developing the methods known from the prior art in such a way that a flexible process for inactivating viruses in a fluid that can be individually adapted to different process conditions.
- Reactive fluid can be taken up separately in each of the containers and incubated for a certain incubation time under certain, in particular adaptable, incubation conditions, while in the mixing arrangement further starting fluid can be mixed with the virus-inactivating reagent.
- Reactive fluid can be taken up separately in each of the containers and incubated for a certain incubation time under certain, in particular adaptable, incubation conditions, while in the mixing arrangement further starting fluid can be mixed with the virus-inactivating reagent.
- the reactive fluid from the first mixing arrangement can then be passed into a second of the containers and incubated without this affecting the incubation in the first of the containers. After incubation in the first container, it can be emptied and the incubated reactive fluid can be further processed, while at the same time the reactive fluid continues to be incubated in the second container. In the first mixing arrangement, further mixing can already take place during this.
- the active viruses are inactivated by incubating the reactive fluid in a container arrangement different from the first mixing arrangement with several separate containers, wherein the reactive fluid is passed from the first mixing arrangement to the container arrangement before incubation.
- the reactive fluid held in the separate containers can easily be incubated for longer, while at the same time the mixing arrangement mixes additional starting fluid and virus-inactivating reagent to form reactive fluid and then directs the reactive fluid into another of the containers without affecting the incubation of the other containers. If, for example, a larger amount of fluid is to be incubated, the reactive fluid can easily be directed into several containers, in particular without the need for complex redesigns.
- Claims 2 and 3 define preferred embodiments with regard to the mixing in the first mixing arrangement.
- the embodiments according to claim 2 enable alternating mixing of fluid in the first mixing arrangement.
- discontinuous inflowing starting fluid can also be mixed with the virus-inactivating reagent to form the reactive fluid by distributing successive input streams of starting fluid to different mixers and/or tangential flow filters.
- the mixing of the starting fluid and the reagent can take place in a first mixer while a second mixer is filled with starting fluid or the reactive fluid of the first mixer can be emptied while the starting fluid and the reagent are mixed in the second mixer.
- a step-by-step adjustment of the pH value can be carried out by increasing or lowering the pH value in several steps according to a preferred embodiment of claim 3.
- Claims 4 and 5 define preferred embodiments with regard to the mixing in a second mixing arrangement and the removal by a separating arrangement.
- An embodiment according to claim 4 with a second mixing arrangement enables the reactive fluid to be mixed with another reagent after the incubation of the fluid and thus stops the inactivation after the viruses in the fluid have been inactivated. It is conceivable, for example, that a pH value that was lowered or increased for inactivation is raised or lowered again and thus neutralization of the virus-inactivating reagent takes place.
- An alternative embodiment according to claim 4 with a separation arrangement enables the virus-inactivating reagent to be removed from the reactive fluid after incubation of the fluid and thus a stopping of the inactivation after the viruses in the fluid have been inactivated.
- An embodiment according to claim 5 with the second mixing arrangement makes it possible in particular to mix discontinuously flowing in reactive fluid with the further reagent to form the resulting fluid by distributing successive input flows to different mixers and/or tangential flow filters. Additionally or alternatively, an embodiment according to claim 5 enables a continuous outflow of resulting fluid. For example, it is possible for a first mixer to be emptied and resulting fluid to flow out, while in a second mixer reacting fluid is mixed with a further reagent to form the resulting fluid. As soon as mixing has taken place in the second mixer, the second mixer can be emptied and the resulting fluid can flow out. For an embodiment according to claim 5 with the separating arrangement, the above-mentioned advantages also arise.
- the embodiment according to claim 6 relates to the filling of the containers with reactive fluid from the first mixing arrangement and the emptying of reactive fluid into the second mixing arrangement or into the separating arrangement from the containers, which can in particular be controlled individually.
- the sequential or simultaneous or at least partially simultaneous filling or emptying enables the method to be adapted particularly easily with regard to the fluid quantities and the incubation times.
- the embodiment according to claim 7 enables a translation of a discontinuous inflow of starting fluid into a continuous outflow of resulting fluid after virus inactivation has taken place.
- This makes it possible to use the method also for input streams of starting fluid that flow in discontinuously due to a previous discontinuous process, such as a previous chromatography, for example a rapid cycling chromatography, or a previous batch process, and at the same time to achieve a continuous outflow.
- a method for incubating a fluid, preferably for inactivating viruses, with the features according to claim 8 is proposed.
- an incubation device for incubating a fluid, in particular for inactivating viruses.
- Such an incubation device can be used, for example, in the proposed methods described above. In this respect, reference may be made to all of the above statements on the proposed methods.
- the incubation device has a second mixing arrangement or a separation arrangement.
- the reactive fluid can be mixed with another reagent that stops the virus inactivation after incubation via the second mixing arrangement.
- the virus-inactivating reagent can be separated from the reactive fluid after incubation via the separation arrangement. This makes it possible, in particular, to stop the inactivation process.
- Claims 11 to 13 define advantageous embodiments with regard to the first mixing arrangement and the second mixing arrangement and the separating arrangement.
- discontinuously flowing fluid can also be mixed by alternately using the mixer(s) and/or the tangential flow filter(s) for mixing, or mixed fluid can flow out continuously by alternately emptying the mixer(s) and/or alternately flowing through the tangential flow filter(s) (claim 11).
- starting fluid can be mixed with a reagent in a first mixer, while a second mixer can be filled with starting fluid at the same time, or reactive fluid can be emptied from the first mixer and starting fluid can be mixed with a reagent in the second mixer at the same time.
- the same advantages arise for an embodiment of the separation arrangement according to claim 11, through which, for example, discontinuously flowing in fluid can also be processed and through which fluid from which the reagent has been removed can flow out continuously.
- the modular expandability of the incubation device (claim 12) makes it possible to adapt it particularly flexibly and individually to the process and the process conditions, in particular without having to make major redesigns to the incubation device.
- a recirculation section (claim 13) it is possible to return the already mixed fluid to a mixer and/or tangential flow filter of the first mixing arrangement and/or to a filter and/or a centrifuge of the second mixing arrangement and to repeat at least part of the mixing process, in particular optionally, or the separation process, i.e. the removal of the reagent, in particular optionally.
- the incubation device has a first distributor and/or a second distributor.
- the reactive fluid from the first mixing arrangement can be conducted into the containers of the container arrangement via the first distributor, and the reactive fluid from the containers of the container arrangement can be conducted into the second mixing arrangement or separation arrangement via the second distributor.
- containers can be optionally connected and/or separated from the first distributor and/or the second distributor.
- the incubation device to be further adapted flexibly and individually to the process and the process conditions without major redesign, for example by connecting containers to the distributors if larger amounts of fluid are to be incubated and/or the incubation time is to be increased, or by separating containers from the distributors if smaller amounts of fluid are to be incubated and/or the incubation time is to be reduced. It is also conceivable to connect containers of different sizes. According to a further embodiment according to claim 15, the containers are designed to be hangable, which enables a particularly space-saving incubation of fluid. A further embodiment according to claim 15 provides that the containers have at least one pressure equalization opening. Pressure equalization in the containers can take place via the pressure equalization opening, so that when the containers are filled and emptied with fluid, no overpressure or underpressure occurs within the containers.
- a weighing device and/or a flow sensor and/or a fill level probe is or are provided, via which the mass, the fill quantity and/or the fill level within the containers can be determined, so that, in particular at any time, it can be determined which containers are filled and/or emptied.
- a pump arranged downstream of the first mixing arrangement in the flow direction pumps the reactive fluid from the first mixing arrangement to the containers and/or a pump arranged downstream of the containers in the flow direction pumps the reactive fluid from the containers to the second mixing arrangement or the separating arrangement.

- the inactivation of the viruses in the reactive fluid F is stopped by mixing the reactive fluid F with another reagent R2, see Fig. 1. While the virus-inactivating reagent R1 can initiate the virus inactivation, this can be stopped by the other reagent R2. This is preferably done after incubation. Alternatively, the inactivation of the viruses in the reactive fluid F is stopped by removing the virus-inactivating reagent R1 from the reactive fluid F, see for example Fig. 3.

- the incubation device 1 is, here and preferably, designed as a single unit. Alternatively, however, it is also conceivable that the incubation device 1 is designed as several units.
- the container arrangement 3 is, here and preferably, fluidically connected to the first mixing arrangement 2. As a result, reactive fluid F can flow from the first mixing arrangement 2 to the container arrangement 3 and the containers 4 can be filled.

- Internals in the present context are means which are at least partially in contact with the reactive fluid F held in the containers 4 and which influence it, such as mixing means such as stirrers, or flow breakers or packings or certain temperature control means. Sensors for measuring properties of the reactive fluid held in the containers 4 are not to be understood as internals in the present context.
- the containers 4 have internals, such as mixing means for homogenizing the fluid held in the containers 4.
- the incubation device 1 preferably has a second mixing arrangement 7 for mixing the reactive fluid F with the further virus inactivation-stopping reagent R2, as shown for example in Fig. 7b). is shown.
- the second mixing arrangement 7 is here and preferably different from the container arrangement 3 and further preferably downstream of the first mixing arrangement 2 and the container arrangement 3 in the flow direction of the fluid.
- the incubation device 1 preferably has a separation arrangement 8 for removing virus-inactivating reagent R1 from the reactive fluid F, see, for example, Fig. 3.
- the separation arrangement 8 is preferably different from the container arrangement 3 and more preferably downstream of the first mixing arrangement 2 and the container arrangement 3 in the flow direction of the fluid.
- the incubation device 1 with the separation arrangement 8 has proven to be particularly useful in cases in which the virus inactivation is stopped, for example, by removing the virus-inactivating reagent R1.
- the separation arrangement 8 preferably comprises at least one separation means, such as a filter 11, such as a tangential flow filter or a membrane filter, and/or a centrifuge, such as a fluidized bed centrifuge.
- the virus-inactivating reagent R1 can be separated from the reactive fluid F via the separation means.
- the second mixing arrangement 7 is structurally identical to the first mixing arrangement 2. Alternatively, however, it is also conceivable that they are structurally different.
- the first mixing arrangement 2 and the second mixing arrangement 7 each have, here and preferably, a dynamic mixer 5, 9.
- the dynamic mixer 5, 9 can be equipped with a driven stirrer, in particular a magnetic stirrer, rod stirrer, etc.
- first mixing arrangement 2 and/or the second mixing arrangement 7 have at least one static mixer 5, 9, as shown in Figures 5, 6 and 8a) for the first mixing arrangement 2, and/or at least one dynamic mixer 5, 9 and/or at least one tangential flow filter 6, 10, in particular a single-pass tangential flow filter, which or which is or are preferably different from the containers 4.
- first mixing arrangement 2 has a dynamic mixer 5
- second mixing arrangement 7 has a tangential flow filter 10.
- static mixers 5, 9 the flow movement of the fluid flowing through the mixer 5, 9 can cause mixing.
- Static mixers 5, 9 are often flowed through by a continuous fluid flow.
- dynamic mixers 5, 9 a movement of mixing elements can cause movement and mixing of the fluid.
- Dynamic mixers are often operated discontinuously, so that the fluid flow flows discontinuously out of the dynamic mixer 5, 9.
- Tangential flow filters 6, 10 In tangential flow filters 6, 10, the flow movement of the fluid flowing through the tangential flow filter 6, 10 can cause mixing. Tangential flow filters 6, 10 are often flowed through by a continuous fluid flow. Tangential flow filters 6, 10 can fulfill a dual function, because tangential flow filters 6, 10 can cause mixing of the fluid flowing through the tangential flow filter 6, 10 and at the same time preferably filter out at least part of the fluid flowing through. In this case, part of the fluid is separated by the tangential flow filter 6, 10 as permeate and the other part of the fluid is separated by the tangential flow filter 6, 10 as retentate. The separation in tangential flow filters 6, 10 can lead to concentration, in particular of the active or inactivated viruses, in the retentate. The concentration can lead to smaller volume flows of the retentate being subsequently processed.
- the tangential flow filter 6 and/or the tangential flow filter 10 can preferably be designed as a single-pass tangential flow filter. In single-pass tangential flow filters, the fluid flows through the filter once and is filtered in the process.

- the mixers 5 are preferably different from the containers 4 and further preferably arranged parallel to one another in terms of flow. Due to the fluidically parallel arrangement, the starting fluid AF can be introduced into the mixers 5 optionally sequentially or partially simultaneously or at the same time. In particular in the case of discontinuous inflow of starting fluid AF, the respective starting fluid AF can thus be mixed in the various mixers 5, in particular alternately.
- one of the two mixers 5 can first be filled with starting fluid AF, the virus-inactivating reagent R1 can be added and the starting fluid AF and the virus-inactivating reagent R1 can be mixed.
- the mixers 5 are designed as dynamic mixers 5
- the mixers 5 are designed as static mixers 5.
- the fluidically parallel arrangement preferably allows fluid to be conducted from one mixer 5 into another mixer 5.

- the first mixing arrangement 2 can alternatively also have two tangential flow filters 6 or at least one mixer 5 and at least one tangential flow filter 6. These are preferably different from the containers 4 and are preferably arranged in parallel or in series with one another in terms of flow.
- the second mixing arrangement 7 has at least two mixers 9.
- the Mixers 9 are, here and preferably, different from the containers 4 and, here and preferably, arranged fluidically parallel to one another. Due to the fluidically parallel arrangement, reactive fluid F can be introduced into the mixers 9 either sequentially or partially simultaneously or at the same time. Reactive fluid F from the containers 4 can be mixed in the various mixers 9, in particular alternately. For example, one of the two mixers 9 can first be filled with reactive fluid F, the additional reagent R2 can be added and the reactive fluid F and the reagent R2 can be mixed to form the resulting fluid RF.
- the fluidically parallel arrangement preferably also allows fluid from one mixer 9 to be optionally conducted into another mixer 9.
