[0001] LIPID NANOPARTICLES WITH RNA FOR COSMETIC TREATMENT

[0002] Sequence Listing

[0003] The application contains a sequence listing which has been submitted electronically in XML format and is hereby incorporated by reference in its entirety. Said XML copy, created on May 29, 2025, is named 12447_012652-WO0.xml and is 239,261 bytes.

[0004] Background

[0005] Traditionally, adipose tissue is categorized into two main types with distinct functions: white adipose tissue (WAT) and brown adipose tissue (BAT). WAT, composed primarily of large, unilocular adipocytes, serves as the body's principal site for storing energy in the form of triglycerides. Conversely, BAT is specialized for energy expenditure through non-shivering thermogenesis, a process driven by the unique mitochondrial protein, Uncoupling Protein 1 (UCP1). Dysfunction within these adipose depots, particularly the excessive expansion and inflammation of WAT characteristic of overweight / obesity, is intimately linked to the development of metabolic disorders and diseases, including impaired glucose tolerance, metabolic syndrome, type 2 diabetes, cardiovascular disease, non-alcoholic fatty liver disease, and at least thirteen different types of cancer. Therefore, understanding and manipulating adipose tissue function represents a significant frontier in treating human disease.

[0006] A paradigm shift in adipose tissue biology occurred with the confirmation of metabolically active BAT in adult humans. That paradigm shift was further expanded by the discovery of inducible “browning” or “beigeing” of WAT. Beige adipose tissue (BeAT) is defined by the emergence or development of cells, in WAT, that express UCP1. The “beigeing” process can be activated by specific stimuli such as chronic cold exposure or treatment with B- adrenergic agonists. Like classical brown adipocytes, beige cells possess multilocular lipid droplets, abundant mitochondria, and express UCP1, enabling them to consume caloric fuel via heat production. This process increases the body's thermogenic capacity.

[0007] UCP1, also known historically as thermogenin, is an inner mitochondrial membrane protein, primarily found in brown and beige adipocytes. UCP1 provides an alternative pathway for proton re-entry into the mitochondrial matrix, effectively bypassing ATP synthase. This regulated "proton leak" dissipates the energy stored in the PMF directly as heat, rather than converting it into chemical energy in the form of ATP. This conversion of the PMF to heat is the core mechanism of non- shivering thermogenesis mediated by brown and beige fat.

[0008] There is an unmet need in the art for an agent to induce UCP1 expression in WAT and other tissues, thereby bypassing natural upstream controls. This strategy offers the potential advantage of inducing thermogenesis independent of external stimuli like cold, while also circumventing the body's inherent negative controls on upregulating heat production. An ideal agent would thus increase local energy expenditure by generating heat and thereby reduce the size of adipose tissue deposits.

[0009] Summary

[0010] To address the above-mentioned unmet needs, the present technology presents methods, compositions and systems for directing a change in the cell state of human WAT to BeAT, agents to achieve that change and systems / protocols for taking advantage of the thermogenic and calorie-expending properties of BeAT in order to achieve local reductions of adipose tissue and systemic change in the properties of adipose tissue.

[0045] Detailed Description

[0046] Detailed descriptions of one or more embodiments are provided herein. It is to be understood, however, that the present disclosure may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in any appropriate manner.

[0047] Brown and / or beige adipocytes (BAs) are a type of adipocyte which are able to uncouple the proton motive force from ATP generation in order to produce thermal energy. This mechanism allows mammals, through non-shivering thermogenesis, to regulate body temperature in cold environments. Because of its metabolically active nature, BAs represent a promising pathway for non-surgical intervention for obesity, aesthetics and other indications.

[0048] Provided herein are novel compositions, methods, formulations and devices to: 1) convert white adipocytes (WAs) to BAs thereby enhancing the metabolic activity of the treated tissue and 2) activate the thermogenic activity of the BAs in the treated tissue so as to consume fatty acids through thermogenesis thereby reducing the appearance of adipose tissue in the treated tissue. WAT includes WAs as well as adipose derived stem cells (ASCs) and other resident cell populations, all of which may also be “browned” and thereby exhibit a similar fatty acid consuming effect.

[0049] Referring to the Sequence Listing incorporated by reference herein, SEQ ID NO:1 was created as an optimized version of the human consensus genomic mRNA encoding for UCP1 including modifications to the 5’ and 3’ UTRs such as inserting a ribosome binding site, a Kozak sequence and a double stop codon. SEQ ID NOs: 2-21 were created as further optimizations of SEQ ID NO:1 using GenScript Biotech Corporation GenSmart tool with several modifications including deleting the 5’ UTR, incorporating Translation Initiator of 5’ UTR (TISU), the genomic human UCP1 5’ UTR, the consensus genomic human fatty acid binding protein 4 (FABP4) 5’ UTR, the consensus genomic human UCP1 3’ UTR, the Cominarty 3’ UTR, and the consensus genomic human beta-globin (HBB) 3' UTR in tandem tail-to-head sequence. For example, SEQ ID NO: 2 is 928 nucleotides long which corresponds identically to nucleotides 54 through 981 of SEQ ID NO: 1. As another example, SEQ ID NO: 3 is 932 nucleotides long which corresponds identically to nucleotides 50 through 981 of SEQ ID NO: 1. As another example, SEQ ID NO: 8 is 1397 nucleotides long and nucleotides 1 through 929 correspond exactly to nucleotides 50 through 979 of SEQ ID NO: 1.

[0074] The consensus genomic coding sequence of UCP1 for Homo sapiens is known. UCP homologs from non-human animals, such as lower primates, horses, cows, pigs, sheep, goats, chicken can also be used with the lipid nanoparticles. The synthetic mRNA may further comprise siRNA, circular RNA, self-replicating mRNA, or mRNA designed for gene editing including but not limited to CRISPR-Cas9 systems. The LNP vesicle may be tailored specifically to enhance transfection of the target adipocytes and WAT. Tailoring of the LNP vesicle may include adjusting the molar ratios of ionizable lipids, helper phospholipids, polyethylene glycol (PEG)- lipids, and sterols as well as immunogenicity-reducing molecules including but not limited to steroids and steroid pro-drugs.

[0075] The “lipid nanoparticle” comprises one or more lipids (e.g., cationic lipids, non-cationic lipids, and PEG-modified lipids) which are formulated to deliver one or more mRNA to one or more target cells. Suitable lipids include, for example, phosphatidyl (e.g., phosphatidylglycerol, phosphatidylcholine, phosphatidylserine, phosphatidylethanolamine, sphingolipids, cerebrosides, and gangliosides). Various polymers may also be incorporated into the lipid vehicles, including, for example, polyacrylates, polyalkycyanoacrylates, polylactide, polylactide-polyglycolide copolymers, polycaprolactones, dextran, albumin, gelatin, alginate, collagen, chitosan, cyclodextrins, dendrimers and poly ethylenimine.

[0076] The lipid nanoparticles can incorporate an ionizable cationic lipid (ICL) to encapsulate and / or enhance the delivery of mRNA into the target cell. A “cationic lipid” refers to any of a number of lipid species that carry a net positive charge at a selected pH, such as physiological pH.

[0077] Non-cationic lipids (NCL) may also be used in the lipid nanoparticles. Non-cationic lipids include, but are not limited to, distearoylphosphatidylcholine (DSPC), dioleoylphosphandylcholine (DOPC), dipalmitoylphosphatidylcholine (DPPC), dioleoylphosphatidylglycerol (DOPG), dipalmitoylphosphatidlylglycerol (DPPG), dioleoylphosphatidylethanolamine (DOPE), palmitoyloleoylphosphatidylcholine (POPC), palmitoyloleol-phosphatidylethanolamine (POPE), dioleoyl-phosphatidylethanolamine 4-(N- maleimidomethylj-cyclohexane- 1 -carboxylate (DOPE-mal), dipalmitoyl phosphatidyl ethanolamine (DPPE), dimyristoylphosphoethanoiamine (DMPE), distearoyl-phosphatidyl- ethanolamine (DSPE), 16-0-monomethyl PE, 16-O-dimethyl PE, 18-1-trans PE, l-stearoyl-2- oleoyl-phosphatidy ethanolamine (SOPE), cholesterol, or a mixture thereof. Such non-cationic lipids may be used alone, but are preferably used in combination with other excipients, for example, cationic lipids. When used in combination with a cationic lipid, the non-cationic lipid may comprise a molar ratio of 5% to about 90%, or preferably about 10% to about 70% of the total lipid present in the transfer vehicle.

[0078] Polyethylene glycol (PEG)-modified phospholipids, PEG / lipid conjugates and derivatized lipids such as DMG- PEG(2000), derivatized ceramides (PEG-CER), including N-Octanoyl- Sphingosine-l-[Succinyl(Methoxy Polyethylene Glycol)-2000] (C8 PEG-2000 ceramide), or ALC-0159 can be incorporated into the lipid nanoparticle. The PEG-modified lipids include, but are not limited to, a polyethylene glycol chain of up to 5 kDa in length covalently attached to a lipid with alkyl chain(s) of C6-C20 length. The PEG-modified phospholipid and derivatized lipids of the present invention can be present at varying molar ratios, e.g., from about 0% to about 20%, about 0.5% to about 20%, about 1% to about 15%, about 4% to about 10%, or about 2% of the total lipid present in the liposomal transfer vehicle.

[0179] In another embodiment, the mRNA of the present disclosure comprises a nucleotide sequence about 80% to about 100%, about 85% to about 100%, about 90% to about 100%, or about 95% to about 100%, identical to the amino acid sequence set forth in SEQ ID NO:1.

[0180] In another embodiment, the mRNA of the present disclosure comprises a nucleotide sequence about 80% to about 100%, about 85% to about 100%, about 90% to about 100%, or about 95% to about 100%, identical to the amino acid sequence set forth in any of SEQ ID NO:2 through SEQ ID NO: 21.

[0181] In an alternative embodiment, the mRNA of the present disclosure comprises a nucleotide sequence about 80% to about 100%, about 85% to about 100%, about 90% to about 100%, or about 95% to about 100%, identical to the amino acid sequence set forth in any of SEQ ID NO: 22 through SEQ ID NO: 129. In another embodiment, a synthetic mRNA, the sequence of may be selected from one of SEQ ID NO: 1 disclosed in the Sequence Listing incorporated by reference herein, encoding for the intracellular synthesis of UCP1 by the ribosomes of a target cell is packaged in a lipid nanoparticle (LNP) vesicle for transfection of WAs or ASCs with the packaged mRNA.

[0182] In another embodiment, cells transfected with a pharmaceutical composition comprising mRNA of SEQ ID NO: 1 will express UCP1 and undergo a process of lipolysis through non-ATP generating respiration, generating heat and reducing the overall FFA content of the transfected and nearby cells.

[0183] In another embodiment, a physician may administer the pharmaceutical composition comprising the mRNA of SEQ ID NO: 1 packaged in an LNP to a patient seeking to accomplish spot fat reduction.

[0184] In another embodiment, a physician administering the mRNA of SEQ ID NO: 1 packaged in an LNP to a patient seeking to accomplish spot fat reduction may administer the pharmaceutical composition in a bolus injection in the targeted area.

[0185] In another embodiment, a physician administering the mRNA of SEQ ID NO: 1 packaged in an LNP to a patient seeking to accomplish spot fat reduction may administer the pharmaceutical composition in a series of injections in the targeted area.

[0186] In another embodiment, a physician administering the mRNA of SEQ ID NO: 1 packaged in an LNP to a patient seeking to accomplish spot fat reduction may administer the pharmaceutical composition transdermally. The transdermal administration may be accomplished through the use of penetration enhancers (e.g. DMSO, oleic acid, lauric acid, sodium lauryl sulfate, sodium ducosate, sodium oleate, cetyltrimethylammonium bromide, benzalkonium chloride, polysorbates, sorbitan esters, polyoxyethylene alkyl ethers, Laurocarpam, propylene glycol monolaurate, lecithin, terpenes), vesicular carriers (e.g. liposomes, ethosomes, niosomes) microneedle injection, iontophoresis, sonophoresis, jet injection or other suitable means.

[0187] Microneedle injectors utilize microscopic needles, typically ranging from 50 to 900 micrometers in length, to bypass the skin's outermost layer, the stratum comeum, and deliver therapeutic agents directly into the underlying epidermal or dermal layers. The microneedles can be disposed in an array on a patch wherein several hundred or several thousand microneedles are disposed. Iontophoresis utilizes a low-level electrical current to facilitate the transport of ions across biological membranes, most notably the skin. The medication is disposed on a patch with an electrode that conducts electricity to drive the ions across the membrane.

[0188] Sonophoresis, also known as phonophoresis, is a non-invasive technique that utilizes ultrasound waves to temporarily increase the permeability of the skin. This enhanced permeability allows for the improved delivery of therapeutic agents, such as medications and cosmetics, across the skin barrier and into deeper tissues.

[0189] Jet injection employs a high-velocity stream of liquid that penetrates the skin to deliver the substance into the underlying tissues. A jet injector creates a very fine, high-pressure jet of liquid that is powerful enough to pierce the skin and reach the desired tissue depth - typically the intradermal, subcutaneous, or intramuscular layer. This is achieved by rapidly forcing a premeasured dose of medication through a tiny orifice in the injector's nozzle.

[0218] In another embodiment, the BeAT may be activated by B3 agonists (e.g. mirabegron), caffeine and like molecules, ibuprofen and like molecules, 4-heptylbenzoic acid; bromododecanoic acid; dodecanoic acid; nonadecanoic acid; oleic acid; retinoic acid; tetradecylthioacetic acid; TTNPB; TUG-891.

[0219] In another embodiment, the protocol prescribed by the treating physician may include a time frame for repeat treatment of the target area with the synthetic mRNA encoding for the intracellular synthesis of UCP1 by the ribosomes of a target cell packaged in an LNP vesicle. The time frame may reflect the rate of turnover of UCP1 in the target cells.

[0220] Examples

[0221] Example 1: The image of Figure 1 was created as follows: Synthetic mRNA expressing mCherry fluorescent protein was synthesized via in vitro transcription from a linearized DNA plasmid. The synthetic mRNA was encapsulated into lipid nanoparticles, yielding a reporter gene test article. Subcutaneous fat was donated by a patient undergoing elective surgery under an IRB -approved protocol. The fat was stabilized for long-term ex vivo culture. The ex vivo fat was treated with the reporter gene test article. Fluorescence and brightfield microscopy images were captured every 4 to 6 hours using an automated system for a total of 48 hours. New red fluorescence in previously non-fluorescent cells indicated successful transfection of ex vivo human fat.

[0222] Example 2: The image of Figure 2 was created as follows: Subcutaneous fat was donated by a patient undergoing elective surgery under an IRB-approved protocol. The fat was stabilized for long-term ex vivo culture. Brightfield microscopy images were captured every 4 to 6 hours using an automated system for a total of 6 days (144 hours). No significant change in the adipocytes’ diameter was observed. The red line marked the diameter of one representative mature adipocyte within the adipose tissue cluster at the start of the experiment (hour 0). The blue line marked the diameter of the same adipocyte at the end of the experiment (hour 144).

[0223] Example 3: The images of Figure 3 were created as follows: Synthetic mRNA expressing UCP1 was synthesized via in vitro transcription from a linearized DNA plasmid. The synthetic mRNA was encapsulated into lipid nanoparticles of composition LNP D of component molar ratio (SM-102: DPSC: Cholesterol: PEG / Lipid Conjugate) of 50:10:38.5:1.5, yielding a drug candidate test article. Subcutaneous fat was donated by a patient undergoing elective surgery under an IRB-approved protocol. The same donated fat was used in this study as in the negative control study (Figure 2). The fat was stabilized for long-term ex vivo culture. The ex vivo fat was treated with the drug candidate test article at full dose (5ug drug candidate per lOOmg of ex vivo fat). Brightfield microscopy images were captured every 4 to 6 hours using an automated system for a total of 6 days (144 hours). Every treated fat cluster shrank significantly, with a majority of the unilocular adipocytes shrinking to the point where they could no longer be visually identified as mature, unilocular adipocytes.

[0224] Example 4: The images of Figure 4 were created as follows: Synthetic mRNA expressing UCP1 was synthesized via in vitro transcription from a linearized DNA plasmid. The synthetic mRNA was encapsulated into lipid nanoparticles, yielding a drug candidate test article. Subcutaneous fat was donated by a patient undergoing elective surgery under an IRB-approved protocol. The same donated fat was used in this study as in the negative control study (Figure 2) and the full-dose study (Figure 3). The fat was stabilized for long-term ex vivo culture. The ex vivo fat was treated with the drug candidate test article at half dose (2.5 pg drug candidate per lOOmg of ex vivo fat). Brightfield microscopy images were captured every 4 to 6 hours using an automated system for a total of 6 days (144 hours). Every treated fat cluster shrank significantly, but less so than with the full-dose. Figures 3 and 4 demonstrate a dose-response curve. The lines in Figure 4 denote the diameter of one representative mature adipocyte within the adipose tissue cluster at the start of the experiment (hour 0) and at the end of the experiment (hour 144).

[0225] Example 5: The image of figure 5 was created as follows: Synthetic mRNA expressing UCP1 was synthesized via in vitro transcription from a linearized DNA plasmid. The synthetic mRNA was encapsulated using Lipofectamine™ MessengerMAX™ Transfection Reagent. Varying doses of the synthetic mRNA were used to treat human adipose-derived stem cells (ASCs) for 48 hours. After 48 hours, the ASCs were lysed, and total protein was isolated. The protein isolated were assayed via Western Blot to provide a semi-quantitative assessment of the amount of UCP1 protein as a function of synthetic mRNA dose.

[0226] Example 6: The sequence of mRNA of SEQ ID NO: 1 was created using A plasmid Editor by M. Wayne Davis (ApE) available through the University of Utah. The coding DNA sequence (CDS) was optimized using the GenScript Biotech Corporation GenSmart tool. The mRNA was manufactured by GeneFab Inc. using N1 -methylpseudouridine as a substitute for uridine and packaged in LNP I as described above. The packaged mRNA was introduced to cultured, ex vivo human white adipose tissue that was prepared by Keliomics Inc. to induce transfection of the mRNA into the tissue culture. After 24 hours the following protocol was performed:

[0227] Culture media was aspirated from the dish; cells were washed in chilled phosphate buffered saline (PBS) and PBS was aspirated completely after wash. Lysis buffer added to the culture dish and supplemented with protease and phosphatase inhibitors. Cells and cell lysate transferred to a pre-chilled microcentrifuge tube. Lysate was incubated on ice for 15-30 mins and then centrifuged at high speed for 20 minutes to pellet cell debris. Supernatant was loaded into a new microcentrifuge tube and protein quantified. Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis (SDS-PAGE), blotting, immunodetection and imaging were performed. The resulting images confirmed the presence of UCP1 in the transfected WAT, as well as expected levels of housekeeping genes heat shock protein 90 (HSP90) and beta-actin ( -actin).

[0228] Figure 6 demonstrates the presence of UCP1 24 hours after lug, 5ug and lOug doses for each 100 mg of ex vivo human WAT and the dose response curve at lug, 5ug and lOug doses. Untreated WAT did not express UCP1 protein. Figures 8 through 14 were generated using automated brightfield microscopy. These images show shrinkage of the transfected WAT in one day intervals from the start to the end point at t+6 days after treatment with a lug dose of mRNA of SEQ ID NO: 1. Figures 15 through 21 show shrinkage of the transfected WAT in one day intervals from the start to the end point at t+6 days after treatment with a 5 ug dose of mRNA of SEQ ID NO: 1.

[0229] Example 7: The sequence of mRNA of SEQ ID NO: 2 was created using A plasmid Editor by M. Wayne Davis (ApE) available through the University of Utah. The coding DNA sequence (CDS) was optimized using the GenScript Biotech Corporation GenSmart tool. The mRNA was manufactured by GeneFab Inc. using N1 -methylpseudouridine as a substitute for uridine and packaged in LNP D as described above. The packaged mRNA was introduced to cultured, ex vivo human white adipose tissue that was prepared by Keliomics Inc. to induce transfection of the mRNA into the tissue culture. After 24 hours the following protocol was performed: Culture media was aspirated from the dish; cells were washed in chilled phosphate buffered saline (PBS) and PBS was aspirated completely after wash. Lysis buffer added to the culture dish and supplemented with protease and phosphatase inhibitors. Cells and cell lysate transferred to a pre-chilled microcentrifuge tube. Lysate was incubated on ice for 15- 30 mins and then centrifuged at high speed for 20 minutes to pellet cell debris. Supernatant was loaded into a new microcentrifuge tube and protein quantified. Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis (SDS-PAGE), blotting, immunodetection and imaging were performed. The resulting images confirmed the presence of UCP1 in the transfected WAT, as well as expected levels of housekeeping gene HSP90.

[0230] Figure 22 demonstrates the presence of UCP1 24 hours after 5 pig and 10 pg doses and the dose response curve at 5 pg and 10 pg doses. Negative control test articles (LNP D encapsulating synthetic mRNA encoding mCherry in lieu of UCP1) and untreated WAT did not express UCP1 protein.

[0231] Example 8: The sequence of mRNA of SEQ ID NO: 1 was created using A plasmid Editor by M. Wayne Davis (ApE) available through the University of Utah. The coding DNA sequence (CDS) was optimized using the GenScript Biotech Corporation GenSmart tool. The mRNA was manufactured by GeneFab Inc. using N1 -methylpseudouridine as a substitute for uridine and packaged in LNP I as described above. One microgram of the packaged mRNA was introduced to a confluent culture of human adipose derived stem cells (ASCs) that was prepared by Keliomics Inc. to induce transfection of the mRNA into the cell culture. After 24 hours the following protocol was performed:

[0232] Culture media was aspirated from the dish; cells were washed in chilled phosphate buffered saline (PBS) and PBS was aspirated completely after wash. Lysis buffer added to the culture dish and supplemented with protease and phosphatase inhibitors. Cells and cell lysate transferred to a pre-chilled microcentrifuge tube. Lysate was incubated on ice for 15- 30 mins and then centrifuged at high speed for 20 minutes to pellet cell debris. Supernatant was loaded into a new microcentrifuge tube and protein quantified. Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis (SDS-PAGE), blotting, immunodetection and imaging were performed. The resulting images confirmed the presence of UCP1 in the transfected WAT, as well as expected levels of housekeeping genes heat shock protein 90 (HSP90) and beta-actin (0- Figure 23 demonstrates the presence of UCP1 24 hours after a 1 pg dose.
