Abstract

The inventive device and methods described herein address the introduction of a safe and effective freeze-dried biological product, and particularly a plasma product, to a subject in need thereof. The present invention relates to a multifunctional, staged closure device, which also is described as a lyophilization container for plasma (LCP). The device and methods described herein address how to reproducibly achieve a low moisture and substantially oxygen-free atmosphere within a finally hermetically sealed biocompatible low aspect plastic vessel within a standard shelf-stoppering freeze dryer. The present inventive device and methods provide a freeze-dried plasma product that is fully traceable, preserves the constituent plasma activity, is readily prepared in a sterile fashion, is stable, ensures ease of storage and permits rapid reconstitution and delivery to a patient.

Claims

1. A multifunctional lyophilization device comprising:

a staged closure lid;

a frame;

a gas permeable membrane; and

an impermeable film.

2. The device of claim 1, wherein the gas permeable membrane is supported on a first broad side of the frame and the impermeable film is supported on a second broad side of the frame.

3. The device of claim 1, wherein the staged closure lid is unidirectional and includes at least one of a base catch and a retaining opening, and wherein the frame includes at least one of a base catch and a retaining opening.

4. The device of claim 3, wherein at least one base catch on one of the unidirectional staged closure lid and the frame, and the at least one retaining opening on one of the unidirectional staged closure lid and the frame, mate at one of multiple fixed positions.

5. The device of claim 4, wherein the at least one base catch and the at least one retaining opening mate at a first fixed position to secure the unidirectional staged closure lid at a height above and spaced away from the gas permeable membrane.

6. The device of claim 4, wherein the at least one base catch and the at least one retaining opening mate at a second fixed position to fully close and uniformly seal the unidirectional staged closure lid to the first broad side of the frame.

7. The device of claim 4, wherein at least one base catch is located on a peripheral edge of the unidirectional staged closure lid and at least one retaining opening is located on a peripheral edge of the frame.

8. The device of claim 2, wherein the frame, the gas permeable membrane, and the impermeable film enclose an interior space.

9. The device of claim 2, wherein the impermeable film is integrally attached on a surface of an outward peripheral base rim of the second broad side of the frame.

10. The device of claim 2, wherein the gas permeable membrane is integrally attached to one of a surface of the frame and a separate rigid frame support.

11. The device of claim 1, wherein the staged closure lid further includes an overhanging surrounding side wall, and wherein the overhanging surrounding side wall further includes cut-outs.

12. The device of claim 1, further comprising at least one of a gasket, a port, and a secondary closure system.

13. A staged shelf stoppered closure system for freezing, freeze-drying, and sealing freeze-dried biological material within a freeze dryer comprising:

a biological material;

a unidirectional staged closure lid;

a frame that peripherally encircles an interior space;

a gas permeable membrane; and

an impermeable film.

14. The system of claim 13, wherein the biological material is human plasma and the device is in a partially closed configuration for freezing and freeze-drying.

15. The system of claim 13, wherein the biological material is human plasma and the device is in a fully closed configuration for sealing.

16. A method of using a multifunctional lyophilization device comprising a unidirectional staged closure lid and a gas permeable membrane to prepare and preserve a biological material comprising:

freezing, freeze-drying, and sealing the biological material within a shelf stoppering freeze dryer.

17. The method of claim 16, further comprising:

freezing and freeze-drying the biological material while the staged closure lid is in a partially closed configuration and spaced away from the gas permeable membrane;

permitting water to sublimate through the gas permeable membrane during freeze-drying;

introducing a gas other than oxygen into the device; and

reducing the water content of the biological material to less than about 1% (w/w).

18. The method of claim 17, further comprising

using the shelf stoppering freeze dryer to move the staged closure lid into a fully closed configuration;

and

sealing the freeze-dried biological material.

19. The method of claim 18, further comprising storing the freeze-dried biological material within the device for at least about two years at 2°

C. to 8°

C., and wherein the biological material is human plasma.

20. The method of claim 19, further comprising substantially preserving the human plasma and reconstituting the substantially preserved human plasma in less than about two minutes.
