Abstract

The invention relates to a system, comprising: a) a sample processing unit, comprising an input port and an output port coupled to a rotating container having at least one sample chamber, the sample processing unit configured provide a first processing step to a sample or to rotate the container so as to apply a centrifugal force to a sample deposited in the chamber and separate at least a first component and a second component of the deposited sample; and b) a sample separation unit coupled to the output port of the sample processing unit, the cell separation unit comprising separation column holder (42), a pump (64) and a plurality of valves (1-11) configured to at least partially control fluid flow through a fluid circuitry and a separation column (40) positioned in the holder, the separation column configured to separate labeled and unlabeled components of sample flowed through the column.

First claim

The invention claimed is:

1. A device for preparing a cell population for therapy for a patient in need thereof,
wherein the device comprises the following components:
a sample processing unit that includes an input port operably connected to a sample chamber, wherein the sample chamber is configured to incubate or culture cells, and is also configured to centrifuge cells contained in the chamber,
a sample separation unit that includes a separation column,
fluid circuitry that interconnects the sample processing unit and the sample separation unit, so that a sample can flow between the sample processing unit and the sample separation unit in either direction;
a pump, and
a plurality of valves that are configured and positioned to control fluid flow through the fluid circuitry;
wherein the components of the device are constructed and arranged so that a user of the device can prepare the cell population according to the following procedure:
receiving a sample of cells through the input port into the sample chamber,
centrifuging the sample in the sample chamber to separate and remove red cells,
transferring the sample from the sample chamber to the sample separation unit,
separating target cells from non-target cells using the separation column, allowing the non-target cells to pass to a waste container,
transferring the separated target cells back to the sample chamber, and
adjusting the cells in an infusion solution to produce a pharmaceutical product having a desired volume or cell concentration;
wherein the components of the device are arranged in a closed system, thereby configuring the device to perform said procedure in a sterile environment whereby the pharmaceutical product produced from the device is suitable for cellular therapy of a patient in need thereof.

2. The device of claim 1 , installed with a disposable single-use tubing set that includes at least the sample chamber, the separation column, and the fluid circuitry.

3. The device of claim 1 , wherein the device is configured to deliver gas and culture medium to the sample chamber to support cultivation of the cells in the chamber.

4. The method of claim 1 , wherein the sample chamber comprises a detection window through which to monitor cells in the chamber during centrifugation.

5. The device of claim 1 , operatively connected with and controlled by a computer.

6. The device of claim 5 , wherein the computer is programmed to control flow of fluids through the fluid circuitry and the separation column, to control placement and/or magnetic field strength of the separation column so as to retain and release magnetically labeled target cells, and thereafter to deliver the pharmaceutical product into an output container for administration to the patient.

7. The device of claim 2 , wherein the sample chamber in the disposable single-use tubing set is configured to receive gas and culture medium to support cultivation of cells in the chamber, and also comprises a detection window through which to monitor cells in the chamber during centrifugation.

8. The device of claim 1 , wherein the components of the device are constructed and arranged so that the user can combine cells in the sample chamber with a reagent that includes DNA, RNA, or a virus that has been introduced into the device, and then cultivate or incubate the cells with the reagent in a cell culture medium in the sample chamber, whereby genetically modified cells are produced.

9. The device of claim 8 , wherein the components of the device are constructed and arranged so that the user can centrifuge the genetically modified cells in the sample chamber to remove a volume of the cell culture medium, and thereafter to combine and the genetically modified cells in an infusion solution for administration to a subject in need thereof.

10. The device of claim 5 , wherein the computer is programmed to perform the following steps:
combine cells in the sample chamber with a reagent that includes DNA, RNA, or a virus,
cultivate or incubate the cells with the reagent in a cell culture medium in the sample chamber whereby genetically modified cells are produced;
centrifuge the genetically modified cells in the sample chamber to remove a volume of the cell culture medium, and thereafter
formulate the genetically modified cells in a suitable volume of an infusion solution for administration to a subject in need thereof.

11. The device of claim 5 , wherein the computer is programmed so that said procedure is fully automated.

12. The device of claim 1 , wherein the components of the device are constructed and arranged so that the user can separate and genetically modify a cell population selected from hematopoietic stem or progenitor cells, T cells, dendritic cells, NK-cells, B-cells, monocytes, and cord blood cells, and thereafter to formulate the genetically modified cells in an infusion solution for administration to a subject in need thereof.

13. The device of claim 12 , wherein cells in the cell population are positive for one or more markers selected from CD133, CD34, CD3, CD4, CD8, CD56, CD19, CD14, CD141 (BDCA-3), CD303 (BDCA-2), CD304 (BDCA-4), CD144, CD10, (BDCA-1), NKp46, NKp80, CD45RO, CD45RA, CD137, CD25, and CD138.

14. The device of claim 1 , wherein the components of the device are constructed and arranged so that the user can introduce magnetic particles into the device, and label target cells bearing a particular cell surface marker with the magnetic particles.

15. The device of claim 1 , wherein the separation column is configured to retain target cells labeled with magnetic particles, while non-target cells that are not labeled with magnetic particles are delivered to the waste container.

16. The device of claim 1 , connected to an output container that contains cells prepared in the device and formulated in an infusion solution for administration to a subject in need thereof, wherein the cells have been genetically modified.

17. A disposable single-use tubing set for installation on a device according to claim 1 , comprising the following components: said sample processing unit with said sample chamber, said separation unit with said separation column, and said fluid circuitry interconnecting the sample processing unit and the sample separation unit,
wherein the components are constructed and arranged for carrying out said procedure.

18. A method of using a device according to claim 13 to prepare a cellular product enriched in target cells, the method comprising:
receiving a sample of cells through the input port into the sample chamber,
