[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 677,991, filed on July 31, 2024, U.S. Provisional Patent Application No.63 / 678,023, filed on July 31, 2024, and U.S. Provisional Patent Application No.63 / 741,295, filed on January 2, 2025, each of which is incorporated by reference herein in its entirety. REFERENCE TO SEQUENCE LISTING

[0002] The Sequence Listing submitted July 31, 2025 as a text file named “38394.0020P1.xml,” created on July 31, 2025, and having a size of 17,589 bytes is hereby incorporated by reference pursuant to 37 C.F.R. § 1.52(e)(5). BACKGROUND

[0003] Cancers that arise from ovary, colorectal, liver or bladder tissue are difficult to identify and to treat due to their tendency to form adhesions on, and penetrate into, visceral organs, the peritoneal lining and the omentum. Further complicating treatment, systemic delivery of chemotherapeutic agents or biologicals to treat peritoneal carcinomatosis is challenging based upon their poor penetration into peritoneal cavity. The diffuse spread of metastatic cells within the peritoneal cavity highlights the need for improved locoregional therapeutic delivery options. The advent of immunotherapies that stimulate host immune cells and reverse the immunosuppressive tumor microenvironment (TME) has improved patient survival in many solid malignancies yet has shown mixed efficacy in treating peritoneal carcinomatoses. Indeed, in some clinical trials, immune checkpoint blockade (ICB) monotherapy has resulted in worse survival outcomes. Resistance to ICB in treating some peritoneal carcinomatoses may be a result of the unique immunological environment in the peritoneal cavity, as ICB-sensitive tumors can turn resistant in this unique metastatic niche. The TME in peritoneal carcinomatosis can consist of solid tumors growing on abdominal and peritoneal lining, and the omentum, the fatty tissue that filters peritoneal fluid and is a common site of ovarian cancer metastasis. In addition, malignant ascites, a hallmark of many peritoneal carcinomatoses, presents as a unique fluid TME. The localization and interplay between these forms of TME present intriguing opportunities and challenges when considering immunotherapeutic treatment of metastatic disease in the peritoneal cavity.

[0004] There is a need for improved compositions and methods for treating cancer. BRIEF SUMMARY

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGSATTORNEY DOCKET NO.38394.0029P1

[0016] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate several embodiments of the disclosed method and compositions and together with the description, serve to explain the principles of the disclosed method and compositions.

[0017] FIGS. 1A-1B show D1 MSCs expressing CD40L, IFN or IL12 induce theexpression of CD86 on splenic dendritic cell (DC) populations: FIG.1A) CD11c+, CD11b- DCs; FIG.1B) CD11c+, CD11b+ DCs. This is an indication that the DCs are activated and primed to present antigen and activate Ag-specific T cells, a necessary attribute of a vaccine adjuvant.

[0018] FIGS.2A-2B show Medinno cargocytes incubated in the presence of fluorescently tagged cell-penetrating peptides (CPP), uniformly take up the peptide and demonstrate high expression (FIG.2A), independent of the peptide sequence. There is no change in cargocyte survival 24 hours post incubation with cell penetrating peptides (FIG.2B).

[0019] FIGS.3A-3C show injection of mice with D1 MSCs expressing an adjuvant (CD40L) and loaded with an OVA cell penetrating peptide (FAM-ISQAV-R9) results in the proliferation of antigen-specific CD4+ T cells. Thus, MSCs (and the enucleated cells described herein) can be utilized as a vaccine platform, delivering both antigen and adjuvant in vivo. T cell activation is observed in the local lymphoid organs draining from the lung (mediastinal lymph nodes and spleen) and non-draining lymphoid organs (inguinal lymph nodes).

[0020] FIGS.4A-4C show antigen-presenting cells are required to facilitate the activation of antigen-specific T cells from an MSC or Cargocyte vaccine platform. FIG.4A) OT-II T cells + mouse MSC-ISQAV-R9 + no spenocytes; FIG.4B) OT-II T cells + mouse MSC-ISQAV-R9 + spenocytes; FIG.4C) OT-II T cells + mouse CA-ISQAV-R9 + spenocytes. D1-MSCs or Cargocytes (CAs) were incubated with an OVA cell penetrating peptide (ISQAV-R9). T cells specific for this peptide (OT-II T cells) only proliferated in vitro when splenocytes were also present in the same well. D1 MSCs or Cargocytes alone, are not sufficient to induce antigen- specific T cell proliferation. DETAILED DESCRIPTION

B. Enucleated Cells

[0034] In some embodiments, the disclosed enucleated cells can be referred to as cargocytes or cytoplasts.

[0035] Disclosed are enucleated cells comprising an exogenous nucleic acid molecule encoding an antigen presenting cell (APC) activator; and an exogenous nucleic acid molecule encoding a cancer antigen. In some embodiments the exogenous nucleic acid molecule can be an exogenous RNA molecule or an exogenous DNA molecule.

[0036] Disclosed are enucleated cells engineered to express an exogenous APC activator and engineered to express a cancer antigen. In some embodiments, the cells can be engineered prior to enucleation. For example, exogenous DNA encoding an APC activator can be introduced into the genome of the cell. In some embodiments the introduction of the exogenous DNA encoding an APC activator can be performed using a viral vector (e.g., lentivirus, adeno- associated virus) and / or Crispr / Cas9. In some embodiments, once the exogenous DNA has been introduced to the cell, the cells can then express or secrete the APC activator, which is maintained after enucleation. Thus, the enucleated cells comprise the APC activator.

[0037] In some embodiments, the engineering of the cells can also be performed for the cancer antigen, not just the APC activator. Furthermore, in some embodiments, the cancer antigen can be introduced as an exogenous peptide by transfection or simply peptide absorption into the cells (e.g., using a cell-penetrating peptide linker to get the cancer antigen into the prior to or after enucleation of the cell).

[0038] In some embodiments, the cells can be engineered after enucleation. Thus, in some embodiments, the exogenous APC activator and / or cancer antigen can be introduced to an enucleated cell. For example, the exogenous RNA molecule that encodes an APC activator can be transfected into an enucleated cell.

[0039] In some embodiments, the enucleated cells of the present disclosure are obtained or derived from a corresponding nucleated cell (referred to herein as a “parent cell”).

In some embodiments, the enucleated cell includes or retains one or more structural features of the parent cell, including intracellular organelles, one or more tunneling nanotubes, or a combination thereof. In some embodiments, the enucleated cell comprises one or more intracellular organelles for synthesis or secretion of an exogenous polypeptide (e.g., APC activator, cancer antigen, therapeutic agent) in absence of the nucleus. In some embodiments, the one or more intracellular organelles comprise a Golgi apparatus, an endoplasmic reticulum, vesicular transport machinery, or a combination thereof. In some embodiments, the enucleated cell comprises or expresses any one of the therapeutic agents described herein. The enucleated cells described herein can also be purified.

In some embodiments, the nucleated cell is a progenitor cell. In some embodiments, the nucleated cell is from a cell line. In some embodiments, the nucleated cell is a suspension cell. In some embodiments, the nucleated cell is an adherent cell. In some embodiments, the nucleated cell is a cell that has been immortalized by expression of an oncogene. In some embodiments, the nucleated cell is immortalized by the expression of human telomerase reverse transcriptase (hTERT) or any oncogene. In some embodiments, the nucleated cell is a patient or subject derived cell (e.g., an autologous patient-derived cell, or an allogenic patient-derived cell).

[0145] In some embodiments, the compositions of the exogenous therapeutic agents are in the form of a capsules, including push fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push fit capsules contain the active ingredients in admixture with filler such as lactose, binders such as starches, and / or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active therapeutic agent is dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In some embodiments, stabilizers are added. A capsuleATTORNEY DOCKET NO.38394.0029P1 may be prepared, for example, by placing the bulk blend of the formulation of the therapeutic agent inside of a capsule. In some embodiments, the formulations (non-aqueous suspensions and solutions) are placed in a soft gelatin capsule. In other embodiments, the formulations are placed in standard gelatin capsules or non-gelatin capsules such as capsules comprising HPMC. In other embodiments, the formulation is placed in a sprinkle capsule, wherein the capsule is swallowed whole or the capsule is opened and the contents sprinkled on food prior to eating.

[0148] In some embodiments, the compositions described herein are self-emulsifying drug delivery systems (SEDDS). Emulsions are dispersions of one immiscible phase in another, usually in the form of droplets. Generally, emulsions are created by vigorous mechanical dispersion. SEDDS, as opposed to emulsions or microemulsions, spontaneously form emulsions when added to an excess of water without any external mechanical dispersion or agitation. An advantage of SEDDS is that only gentle mixing is required to distribute the droplets throughout the solution. Additionally, water or the aqueous phase is optionally added just prior to administration, which ensures stability of an unstable or hydrophobic active ingredient. Thus, the SEDDS provides an effective delivery system for oral and parenteral delivery of hydrophobic active ingredients. In some embodiments, SEDDS provides improvements in the bioavailability of hydrophobic active ingredients.

[0149] The compositions (e.g., pharmaceutical compositions) described herein may be formulated for administration to a subject by administration routes, including but not limited to, intravenous, intraarterial, oral, parenteral, buccal, topical, transdermal, rectal, intramuscular, subcutaneous, intraosseous, transmucosal, inhalation, or intraperitoneal administration routes.

[0158] An aerosol formulation for nasal administration is generally an aqueous solution designed to be administered to the nasal passages in drops or sprays. Nasal solutions may be similar to nasal secretions in that they are generally isotonic and slightly buffered to maintain a pH of about 5.5 to about 6.5, although pH values outside of this range may additionally be used. Antimicrobial agents or preservatives may also be included in the formulation.

[0159] An aerosol formulation for inhalations and inhalants may be designed so that the agent or combination of agents is carried into the respiratory tree of the subject when administered by the nasal or oral respiratory route. Inhalation solutions may be administered, for example, by a nebulizer. Inhalations or insufflations, comprising finely powdered or liquid drugs, may be delivered to the respiratory system as a pharmaceutical aerosol of a solution or suspension of the agent or combination of agents in a propellant, e.g., to aid in disbursement. Propellants may be liquefied gases, comprising halocarbons, for example, fluorocarbons such as fluorinated chlorinated hydrocarbons, hydrochlorofluorocarbons, and hydrochlorocarbons, as well as hydrocarbons and hydrocarbon ethers.

[0160] Aerosol formulations may also comprise other components, for example, ethanol, isopropanol, propylene glycol, as well as surfactants or other components such as oils and detergents. These components may serve to stabilize the formulation and / or lubricate valve components.

ExamplesA. Example 1 - MSCs expressing CD40L or IFN induce the expression of CD86 onsplenic dendritic cell (DC) populations

[0190] MSCs expressing CD40L or IFN induce the expression of CD86 on splenicdendritic cell (DC) populations. This is an indication that the DCs are activated and primed to present antigen and activate Ag-specific T cells, a necessary attribute of a vaccine adjuvant. CD86 expression is a measure of the activation of an APC.

[0191] MSCs were infected (VSV-IFN ) or transfected with plasmid DNA (CD40L) ormRNA (IFN or IL12) and seeded in 24-well plates. C57BL / 6 splenocytes were isolated bymechanical separation and red blood cells were lysed. Splenocytes were then plated over MSCs in the well. In some wells, Poly(I:C) was added as a positive control. Cells were incubated forATTORNEY DOCKET NO.38394.0029P1 24 hours then collected and stained with a cocktail of antibodies in the presence of Fc block. Cells were analyzed on a FACSFortessa X20 and phenotypes were identified using FlowJo. Data is mean ± SD of triplicates. CD86 expression is shown in Fig.1A and Fig.1B. B. Example 2 - Cargocytes incubated in the presence of fluorescently tagged cell- penetrating peptides (CPP), uniformly take up the peptide and demonstrate high expression (A), independent of the peptide sequence

[0192] To show the expression of the antigen in the cargocyte, cargocytes were incubated in the presence of fluorescently tagged cell-penetrating peptides (CPP), uniformly take up the peptide and demonstrate high expression (Fig.2A), independent of the peptide sequence. There is no change in cargocyte survival 24 hours post incubation with cell penetrating peptides (Fig. 2B).

[0193] Cell penetrating peptides (CPPs) were reconstituted in PBS. Peptide sequences: FAM-ISQAV-R9 (FAM-ISQAVHAAHAEINEAGRRRRRRRRRR), Cy3-SIINFEKL-R9 (Cy3- SIINFEKLRRRRRRRRR). Cargocytes were thawed and resuspended in media without antibiotics. CPPs were added at different concentrations. Cargocytes were incubated at 37°C for 30 minutes and then washed. (Fig.2A) Fluorescent intensity of CPPs was analyzed by flow cytometry using a FACSCelesta. (Fig.2B) Cargcoyte survival was assessed.300K Cargocytes were plated over fibronectin and incubated for 24 hours. Cargocytes that were still alive and attached to the plate were lifted and counted using a Countess cell counter. Data is mean ± SD of technical triplicates.

[0194] The cargocytes of FIG.2 are Medinno cargocytes which refers to cargocytes, or enucleated cells as described herein, that are derived from the Med C. Example 3 - MSCs expressing and adjuvant (CD40L) and loaded with an OVA cell penetrating peptide (FAM-ISQAV-R9) results in the proliferation of antigen-specific CD4+ T cells

[0195] Injection of mice with MSCs expressing and adjuvant (CD40L) and loaded with an OVA cell penetrating peptide (FAM-ISQAV-R9) results in the proliferation of antigen-specific CD4+ T cells. MSCs and Cargocytes can be utilized as a vaccine platform, delivering both antigen and adjuvant in vivo. T cell activation is observed in the local lymphoid organs draining from the lung (mediastinal lymph nodes and spleen) and non-draining lymphoid organs (inguinal lymph nodes).

[0196] CD4+ T cells were isolated from the spleens and inguinal lymph nodes of female OT-II mice by negative bead selection following mechanical separation. T cells were then stained with CellTrace Far red and 2x106T cells were injected in the retro-orbital cavity of 12ATTORNEY DOCKET NO.38394.0029P1 recipient female C57BL / 6 mice.24 hours later, MSCs transfected with CD40L plasmid werethawed and incubated with 50 M Fam-ISQAV-R9 peptide. 1x106 CD40L-FAM-ISQAV-R9MSCs were injected into the later tail veins of 5 recipient mice.5 other recipient mice wereinjected with 200 g ovalbumin (OVA) + 50 g Poly(I:C). 5 days later mice were euthanized andspleens (Fig.3A) and lung draining mediastinal lymph nodes (MedLN) (Fig.3B) and non- draining inguinal lymph nodes (iLN) (Fig.3C) were collected. Single cells suspensions from organs was generated by mechanical separation, red blood cells were lysed, and cells were subjected to antibody staining. Cells were processed on a FACSFortessaX20 and analyzed by Flow Jo. Proliferation was examined by dilution of CellTrace Far red in Live, CD45+, CD3+, CD4+ T cells. Division index, the average number of cell divisions that a cell in the original population has undergone, was determined using FlowJo analysis software. Data is mean ± SEM of n=2 (untreated) or n=5 (treated groups). D. Example 4 - Antigen-presenting cells are required to facilitate the activation of antigen- specific T cells from an MSC or Cargocyte vaccine platform

[0197] Antigen-presenting cells are required to facilitate the activation of antigen-specific T cells from an MSC or Cargocyte vaccine platform. MSCs or Cargocytes (CAs) were incubated with an OVA cell penetrating peptide (ISQAV-R9). T cells specific for this peptide (OT-II T cells) only proliferated in vitro when splenocytes were also present in the same well. MSCs or cargocytes alone, are not sufficient to induce antigen-specific T cell proliferation.

[0198] CD4+ T cells, previously isolated from the spleens and inguinal lymph nodes of female OT-II mice by negative bead selection following mechanical separation and frozen, were thawed and rested in complete media overnight at 37°C. MSCs or Cargocytes were thawed,incubated with 50 M ISQAV-R9 CPP as previously described and plated in 24-well plates.C57BL / 6 splenocytes were isolated by mechanical separation and red blood cells were lysed. Splenocytes were then plated over MSCs in some of the wells and added to all wells. T cellswere collected and plated over MSCs and splenocytes. 30 g / mL Poly(I:C) was added to wells toactivate splenocytes.5 days later, wells were examined under phase contrast for evidence of T cell proliferation as evidenced by expansion and growth of small lymphocytes in grape-like clusters (pink arrows). Images in Fig.4A, 4B, and 4C are representative of experimental triplicates.

[0199] The cargocyte vaccine platform described in this example refers to one or more of the disclosed enucleated cells comprising an antigen presenting cell activator and a cancer antigen.
