Targeting multiple immune mechanisms may overcome therapy resistance and further improve cancer immunotherapy for humans. Here, we describe the application of virus-like vesicles (VLV) for delivery of three immunomodulators alone and in combination, as a promising approach for cancer immunotherapy. VLV vectors were designed to deliver single chain interleukin (IL)-12, short-hairpin RNA (shRNA) targeting programmed death ligand 1 (PD-L1), and a dominant-negative form of IL-17 receptor A (dn-IL17RA) as a single payload or as a combination payload. Intralesional delivery of the VLV vector expressing IL-12 alone, as well as the trivalent vector (designated CARG-2020) eradicated large established tumors. However, only CARG-2020 prevented tumor recurrence and provided long-term survival benefit to the tumor-bearing mice, indicating a benefit of the combined immunomodulation. The abscopal effects of CARG-2020 on the non-injected contralateral tumors, as well as protection from the tumor cell re-challenge, suggest immune-mediated mechanism of protection and establishment of immunological memory. Mechanistically, CARG-2020 potently activates Th1 immune mechanisms and inhibits expression of genes related to T cell exhaustion and cancer-promoting inflammation. The ability of CARG-2020 to prevent tumor recurrence and to provide survival benefit makes it a promising candidate for its development for human cancer immunotherapy.

Chemotherapy is the most prominent route in cancer therapy for prolonging the lifespan of cancer patients. However, its non-target specificity and the resulting off-target cytotoxicities have been reported. Recent in vitro and in vivo studies using magnetic nanocomposites (MNCs) for magnetothermal chemotherapy may potentially improve the therapeutic outcome by increasing the target selectivity. In this review, magnetic hyperthermia therapy and magnetic targeting using drug-loaded MNCs are revisited, focusing on magnetism, the fabrication and structures of magnetic nanoparticles, surface modifications, biocompatible coating, shape, size, and other important physicochemical properties of MNCs, along with the parameters of the hyperthermia therapy and external magnetic field. Due to the limited drug-loading capacity and low biocompatibility, the use of magnetic nanoparticles (MNPs) as drug delivery system has lost traction. In contrast, MNCs show higher biocompatibility, multifunctional physicochemical properties, high drug encapsulation, and multi-stages of controlled release for localized synergistic chemo-thermotherapy. Further, combining various forms of magnetic cores and pH-sensitive coating agents can generate a more robust pH, magneto, and thermo-responsive drug delivery system. Thus, MNCs are ideal candidate as smart and remotely guided drug delivery system due to a) their magneto effects and guide-ability by the external magnetic fields, b) on-demand drug release performance, and c) thermo-chemosensitization under an applied alternating magnetic field where the tumor is selectively incinerated without harming surrounding non-tumor tissues. Given the important effects of synthesis methods, surface modifications, and coating of MNCs on their anticancer properties, we reviewed the most recent studies on magnetic hyperthermia, targeted drug delivery systems in cancer therapy, and magnetothermal chemotherapy to provide insights on the current development of MNC-based anticancer nanocarrier.

Abstract 1150: CARG-2020 artificial oncolytic virus delivering three immune-modulators prevents tumor recurrence in a syngeneic model of ovarian cancer

AbstractBackground: Ovarian cancer is the most lethal of all gynecologic malignancies with a grim 5-year survival rate of ~47%. Mortality occurs in the setting of recurrent disease wherein the co-presentation of chemoresistance and carcinomatosis limits the value of standard of care. It is therefore imperative to develop approaches that can prevent recurrent ovarian cancer. Oncolytic viruses are genetically modified replication competent viruses that can selectively infect cancer cells to induce cell lysis and death. This approach has proven to be clinically safe making it a promising approach to complement standard of care. The objective of this study is to evaluate the efficacy of CARG-2020, a virus-like vesicles (VLV) delivering three immune-modulators including IL-12, IL-17 antagonist and shRNA-PD-L1 in preventing recurrent disease in a syngeneic mouse model of recurrent ovarian cancer.Materials and Methods: In vitro: Triple knockout (TKO; p53LSL-R172H/Dicerflox/flox/Ptenflox/flox) mouse ovarian cancer cells were seeded in 96-well plates and treated with different doses of CARG-2020. Cell death was determined using the Incucyte imaging system. In vivo: TKO ovarian cancer cells stably expressing the mCherry fluorescent protein were injected i.p. in C57bl/6 mice (day 0) to mimic the establishment of recurrent disease. Treatment commenced on day 3 with the treatment group receiving three doses of 1x10^8 PFU of CARG-2020 given every other day (n=5). Control group received PBS (n=5). Both treatments were given i.p. Tumor growth was monitored by live imaging using mCherry fluorescence ROI area. Progression-free survival (PFS) was defined as the day ROI area reached 2,000.Results: CARG-2020 (1x10^5 PFU) demonstrated cytolytic effect in vitro and induced 100% cell death within 24h. In vivo, CARG-2020 induced significant decrease in i.p. tumor growth (p = 0.0128) compared to PBS control. Treatment with CARG-2020 completely delayed the establishment of recurrent disease (PFS, p = 0.0003). Whereas PBS control group demonstrated median PFS of 20 days, mice in the CARG-2020 group remained disease-free until day 60.Conclusion: CARG-2020 is able to prevent the establishment of recurrent disease in a syngeneic mouse model of recurrent ovarian cancer. Our results provide rationale for the further development of this platform as a therapeutic modality for ovarian cancer patients.Citation Format: Ayesha B.
