Abstract

Cartridge for manufacturing a population of cells suitable for formulation as a cellular therapeutic are disclosed herein, along with systems for operating the cartridges and performing methods to generate the population of cells suitable for formulation as a cellular therapeutic. The population of cells suitable for formulation as a cellular therapeutic can be T-cells, including CAR T-cells. The systems and methods can be largely automated.

First claim

What is claimed:

1 . A cartridge for manufacturing a population of cells, comprising:
a sealed enclosure with an inlet port and an outlet port, comprising: a first fluidic network connected to the outlet port; a first reagent reservoir connected to the first fluidic network; a first cell analysis region connected to the first fluidic network; and a chamber for culturing cells, wherein the chamber comprises: a first input opening for introduction of fluid into the chamber; a first output opening for removal of fluid from the chamber; and a second output opening for removal of fluid from the chamber;
wherein:
the chamber is connected to each of the outlet port, the first reagent reservoir, and the first cell analysis region via the first fluidic network;
the first and second output openings are positioned at different vertical elevations within the chamber; and
an internal surface of a base of the chamber comprises a plurality of concave features defined thereon.

2 . The cartridge of claim 1 , wherein the first output opening of the chamber is located in the base of the chamber, wherein the second output opening of the chamber is located above the base, and wherein the second output opening is located at or above a position in the chamber that corresponds to at least 15% of a vertical height of the chamber.

3 . The cartridge of claim 1 , wherein the first fluidic network comprises a plurality of valves and a plurality of channels.

4 . The cartridge of claim 3 , wherein a single valve in the plurality of valves of the first fluidic network is connected to, and thereby regulates flow through, the first output opening and/or the second output opening of the chamber, and wherein the single valve of the first fluidic network is directed connected to, and thereby regulates flow through, both the first output opening and the second output opening of the chamber.

5 . The cartridge of claim 1 further comprising: a second fluidic network, and wherein the second fluidic network comprises a plurality of valves and a plurality of channels.

6 . The cartridge of claim 5 , wherein the second fluidic network is connected to the inlet port or the first input opening of the chamber.

7 . The cartridge of claim 5 , further comprising: a first reservoir for cell culture medium, and wherein the first reservoir is connected to the second fluidic network.

8 . The cartridge of claim 7 , wherein the first reservoir for cell culture medium is connected to the chamber via the first input opening of the chamber.

9 . The cartridge of claim 1 , further comprising: a second reservoir for collecting waste material, and wherein the second reservoir is connected to the first fluidic network.

10 . The cartridge of claim 9 , wherein the second reservoir for collecting waste material is connected to the chamber via at least one outlet opening of the first outlet opening, and the second outlet opening, or a third outlet opening of the chamber.

11 . The cartridge of claim 9 , wherein the second reservoir for collecting waste material comprises a second compartment located within the cartridge.

12 . The cartridge of claim 1 , wherein each concave feature of the plurality of concave features on the internal surface of the base of the chamber has a volume of about 500 nanoliters to about 20 microliters.

13 . The cartridge of claim 1 , wherein each concave feature of the plurality of concave features on the internal surface of the base of the first chamber defines a hemi-spherical cavity.

14 . The cartridge of claim 1 , wherein each concave feature of the plurality of concave features on the internal surface of the base of the chamber defines an elongated cavity and wherein a long axis of each elongated cavity is substantially parallel to a long access of every other elongated cavity of the plurality of concave features.

15 . The cartridge of claim 14 , wherein each elongated cavity includes a deepest point, wherein the long axis of each elongated cavity includes a first end and a second end, wherein an angle defined by the internal surface of the base of the chamber and a line segment connecting the first end of the long axis with the deepest point of the elongated cavity is between 45° and 90°, and wherein an angle defined by the internal surface of the base of the chamber and a line segment connecting the second end of the long axis with the deepest point of the elongated cavity is less than 45°.

16 . The cartridge of claim 1 , wherein each concave feature of the plurality of concave features on the internal surface of the base of the first chamber comprises a surface for activating a T lymphocyte (T cell).

17 . The cartridge of claim 16 , wherein the surface for activating a T cell comprises an antigen-presenting surface.

18 . The cartridge of claim 16 , wherein the surface for activating a T cell covers a portion of a surface of each concave feature.

19 . The cartridge of claim 18 , wherein the surface for activating a T cell comprises a first region that is a T cell activating region and a second region that is covalently modified with surface blocking ligands.

20 . The cartridge of claim 19 , wherein the first region of each concave feature comprises an area of between 0.5 mm 2 and 1.0 mm 2 .

21 . The cartridge of claim 1 , wherein the concave features of the internal surface of the base of the first chamber comprises 100s to 1000s of concave features.

22 . The cartridge of claim 1 , wherein the chamber further comprises a moveable lid for controlling an inner volume of the chamber.

23 . The cartridge of claim 22 , wherein the moveable lid of the chamber has a maximally expanded position during which the chamber comprises a volume between 10 cubic centimeters (cm 3 ) and 150 cm 3 .

24 . The cartridge of claim 22 , wherein the moveable lid of the chamber has a minimally expanded position during which the chamber comprises a volume less than 2 cm 3 .

25 . The cartridge of claim 1 , wherein the first reagent reservoir is configured to store a cytokine.

26 . The cartridge of claim 1 further comprising a second reagent reservoir connected to the first fluidic network.

27 . The cartridge of claim 26 , wherein the second reagent reservoir is configured to store a cytokine, a reagent for transfecting/transforming cells, or a cell staining reagent.

28 . The cartridge of claim 1 , wherein the first cell analysis region is configured for counting cells and/or detecting cells having a desirable and/or undesirable phenotype.

29 . The cartridge of claim 1 , wherein the chamber is a first chamber and the cartridge further comprises a second chamber for culturing cells, wherein the second chamber comprises:
