A recently filed patent (Publication Number: US20230241251A1) describes a pharmaceutical composition that includes a replication defective herpes simplex virus (HSV) genome and one or more heterologous polypeptides for stimulating an immune response. The recombinant HSV genome encodes human cytokines or human chemokines, which are proteins that play a role in immune system regulation. The composition also includes a pharmaceutically acceptable excipient, which is a substance used as a carrier or vehicle for the active ingredients.

The patent claims specify various aspects of the pharmaceutical composition. For example, claim 131 states that the recombinant HSV genome does not have an inactivating mutation in an ICP27 gene. Claim 132 mentions that the recombinant HSV genome can be either HSV-1 or HSV-2. Claim 134 states that the recombinant HSV genome may have an inactivating mutation in certain herpes simplex virus genes. Claim 139 lists several human cytokines and human chemokines that can be included in the composition, such as Interleukins, Tumor Necrosis Factor alpha, and Interferon gamma.

The patent also describes the suitability of the pharmaceutical composition for various routes of administration, including topical, oral, intravenous, and inhaled. It specifies that the composition is not a vaccine and does not encode an antigen. Additionally, claim 146 highlights that the human cytokine used in the composition is not Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF). Claim 157 mentions that the composition can be used for cancer treatment.

Overall, the patent presents a pharmaceutical composition that utilizes a replication defective herpes simplex virus genome to deliver human cytokines or human chemokines for stimulating an immune response. The composition can be administered through various routes and has potential applications in cancer treatment.
