Description

FROZEN THERAPEUTIC DOSE AND PACKAGE

BACKGROUND OF THE INVENTION

Cross Reference to Related Application

[0001 ] This application claims the benefit and priority to U.S. provisional patent application no. 62012388, filed on June 15, 2014 and entitled Frozen

Therapeutic Dose and Package: the entirety of which is incorporated by reference herein.

Fieid of the invention

[0002] The present invention relates to a frozen therapeutic dose comprising an amniotic materia! and packaging for said dose. In an exemplary embodiment a frozen therapeutic dose comprises iive amniotic stem ceiis

Background

[0003] Therapeutic compositions comprising amniotic fluid, tissue, and in particular amniotic stem ceils are being used to treat a wide variety of conditions and alignments. Active or live stem cells are critically important in the treatment of some conditions and patients hav to visit a doctors office to receive these treatments. Some conditions require the regular application, or injection of therapeutic compositions comprising amniotic stem cells which requires the patient to make frequent trips to the doctor's office. This is inconvenient and in some cases

impractical, especially when a dose of an amniotic stem celi therapeutic composition is required multiple times a day,

[0004] Amniotic stem cel!s are somewhat fragile and can become damaged or die for an number of reasons including exposure to chemicals, exposure to excessive heat or simply time,

SUMMARY OF THE INVENTION

[0005] The invention is directed to a frozen therapeutic dose comprising an amniotic material and packaging for said dose. Any of the therapeutic compositions described in U.S. provisional patent application no,: 61/949,087, filed on March 30,

i 2014 and entitled Therapeutic Compositions and Methods of Use, or U.S. provisional patent application no.: 62/012394, filed on June 15, 2014 and entitled Aceliular Amnion Derived Therapeutic Composition, may be configured as a frozen

therapeutic dose, as described herein, and both of these references are incorporated by reference herein in their entirety, in an exemplary embodiment, a frozen therapeutic dose comprises live amniotic stem ceils. A frozen therapeutic dose may be provided in a form, such as a mutti-pack form, to enable a person to administer a dose to a treatment location without the need of traveling to a doctor's office or clinic. A frozen therapeutic dose package may be kept in a conventional freezer at -20°C, for example, for extended periods of time and a person may remove the package as needed for treatment. Many conditions require the administering of a therapeutic dose every day or multiple times a day and traveling to a treatment location that often is not practical for many people.

[0006] A frozen dose may keep the amnion material and in particular the live amniotic stem ceils viable for extended persods of time. Live amniotic stem cells may remain iive and viable even after being frozen for certain periods of time. A cryoprotectant may be required in some cases to protect the amnion materia! and in particular to preserver the viability of the amniotic stem cells. Any suitable type of cyroprotectant may be used including, but not limited to, glycols, ethylene glycol, propylene glycol, glycerol, 2-methyi-2,4~pentanediol (MFD), alcohols, dimethyl sulfoxide (DMSG), sugars, poiyols, glucose and the like, Some of the cryprotectamts may raise the pH and a buffer may be needed to reduce this elevated pH prior to administering to a treatment location.

[000? 3 A therapeutic dose, as used herein comprises amniotic materia! including, but not limited to, amniotic membrane, amniotic fluid, amniotic stem ceiis, and/or cytokines, collagen, proteins, and growth factors derived from amnion materia!. In an exemplary embodiment, a frozen therapeutic dose comprises live amniotic stem ceils. A therapeutic dose may aiso comprise a diluent, a

cryoprotectant, a buffer or other materials configured to enhance the effectiveness of the treatment, in one embodiment, a therapeutic dose comprises amnion material and a buffer to reduce the Ph of a cryoprotectant In another embodiment, an therapeutic does comprises anti-inflammatory nano-particies and/or statins, HMG- CoA reductase inhibitors to reduce inflation at a treatment location. A diluent may be comprise a saiine solution, water, a plasma containing solution, such as P!asma Lyte from Baxter Inc. in some embodiments, it may be desired to have a viscous frozen dose upon thawing or me!ting. It may be desirable to slow the absorption of the frozen dose into a treatment location. A hydrogel may be used as a diluent and may provide for a high viscosity thawed frozen dose, and may prolong the time the therapeutic frozen dose is in contact with a treatment location. Any suitable type of hydfogei may be combined with the therapeutic composition.

[0008] In an exemplary embodiment, a therapeutic dose comprise a concentration of live amniotic stem ceils of at least about 0.5 x 10b celi/mi or more, about 1 x 106 cell/ml or more, about 2 x 10s cell/mi or more and any range between and including the values provided. In one embodiment, amniotic stem cells are concentrated in the therapeutic dose, whereby the concentration is substantially higher than an initial concentration before processing.

jO009] A frozen therapeutic dose may be configured in a dosing package having a dose compartment and a compartment closure. An individual dosing package may be relatively small, such as no more than about 100ml, no more than about 50ml, no more than about 25ml, no more than about 10ml, no more than about 5mi and an range between and including the volumes provided. In an exemplary embodiment, a frozen therapeutic dose is provided in a detachable dosing package that is part of a muiii-dose pack. For example, two or more detachable dosing packages may be coupled together in a multi-dose pack and a separation feature, such as perforations, may be used for detachment. Any number of detachable dosing packages may be configured in a muifi-dose pack including more than three, more than five, more than ten, more than twenty and the like.

[00] j A dosing package may comprise a frozen therapeutic dose and a secondary materia! within a singie compartment whereby the frozen materials are substantiall separate and will not mix until they thaw. For example, a frozen therapeutic dose of amniotic stem cells may be frozen and a cryoprotectant may be added to ensure that the stem celt are live upon thawing. The cryoprotectant may be an irritant for some treatment locations, such as the eye, and therefore a buffer or buffer solution is added to the dosing package compartment in a frozen state. The two solid materials within the dosing package compartment will stay substantially separate and will not mix until the contents of the compartment are thawed, !n this way, the therapeutic dose applied to a treatment location will not be irritating. A secondary material may be configured within a single dose compartment including, but not limited to. a diluent, a buffer, a secondary therapeutic composition and the like.

[00! 1 ] In another embodiment, a secondary materia! or component of a therapeutic dose is provided in a separate compartment, whereby the contents of the secondary compartment are added to the frozen dose before application to a treatment location. A set of compartments, one with a frozen therapeutic dose of amnion materia!, and a another with a secondary materia! including, but not limited to, a diluent, a buffer, a secondary therapeutic composition and the like, may be coupled together. A muiti-dose pack may comprise a separation feature that is configured to detach th two compartments. A secondary therapeutic composition, may comprise amnion material and may have a different composition than a first therapeutic composition.

10012] A frozen dose may be configure to be removed from a dose

compartment and placed directly onto a treatment location. For example, a frozen dose pellet may be removed from a dose compartment and placed on the eye or under an eyelid. In another embodiment, a frozen dose may be piaced in an applicator, such as a dropper, spray bottle, or syringe for example. A diluent, buffe or other secondary material ma be added to an applicator. A frozen dose may be allowed to thaw prior to application to a treatment location, or melt in a secondary material.

[0013] In another embodiment, a frozen therapeutic dose is coupled with a compartment closure, whereby the compartment closure can be removed from the compartment and the therapeutic dose applied to a treatment location. For example, a frozen dose may be configured in a bliste pack having a peel off compartment closure. The frozen dose may be attached to the pee! way compartment closure whereby upon removal of the closure it can be applied directly to a treatment location, such as the skin, eye, mouth, etc. !n another embodiment a frozen dose is attached to a closure cap and upon removal can be swabbed over a treatment area, or p!aeed in or on the mouth.

[0014] In stil! another embodiment, a f oze dose is configured in a dose package applicator comprising a compartment closure and at least one opening in a compartment cover. In this embodiment, the compartment closure, such as a foil sheet, can be removed to expose the compartment cover having at least one opening therein. The dose package applicator can be placed directly on a treatment location and the compartment can be pressed to enable the therapeutic composition to pass through the opening. In another embodiment, a compartment cover may be a porous materia! that enables the therapeutic composition to transfer therethrough as it thaws.

[00 i 5] The therapeutic composition may also be administered by a syringe or iranscatheier. A frozen dose may be removed from a dose package and then drawn into a syringe. The syringe may then be used to inject the therapeutic composition to any suitable treatment location.

[001 3 A therapeutic composition may be applied to a treatment location by topical application, ingestion, injection, transcatheter and the like. In addition, som conditions may require some combination of the application methods described herein.

|00ί 7] A therapeutic composition may be applied to any suitable treatment location including, but not limited to, topically to the exterior of the body including the skin, a wound, a scare, a wrinkle and the like, to the digestive system by ingestion or injeciion, to an organ by injection or by direct application during surgery, for example.

[0018] The summary of the invention is provided as a general introduction to some of the embodiments of the invention, and is not intended to be limiting.

Additional example embodiments including variations and alternative configurations of the invention are provided herein.
