  "patent_number": "US 12734225",
  "country": "US",
  "title": "New Peptide Vaccines for Fighting Cancer",
  "original_title": "Fusion peptide vaccines",
  "summary": "This patent describes new protein fragments, called polypeptides, designed to help the body's immune system fight specific cancers like lung, stomach, and skin cancer.",
  "what_it_does": "The patent covers specific protein pieces, or polypeptides, that are designed to trigger a strong immune response against cancer cells. These peptides contain parts, known as T cell epitopes, that are recognized by the immune system's T cells. The goal is to teach the T cells to attack and destroy cancer cells, particularly in cancers like gastric cancer, lung cancer, melanoma, and bladder cancer. The patent also mentions using these peptides in pharmaceutical compositions, meaning they are formulated into medicines, and suggests methods for identifying patients who would benefit most from this treatment.",
  "what_it_does_not_cover": [
    "Does not cover vaccines for infectious diseases like the flu or COVID-19.",
    "Does not cover general cancer treatments that don't use specific T cell epitopes.",
    "Does not cover diagnostic methods unrelated to identifying patients for peptide vaccine treatment.",
    "Does not cover the use of whole proteins or DNA/RNA in the vaccine formulation.",
    "Does not cover treatments for cancers not listed in the patent, such as brain tumors or leukemia."

  "abstract": "The disclosure relates to polypeptides and pharmaceutical compositions comprising polypeptides that find use in the prevention or treatment of cancer, in particular gastric cancer, lung cancer, melanoma and bladder cancer. The disclosure also relates to methods of inducing a cytotoxic T cell response in a subject or treating cancer by administering pharmaceutical compositions comprising the peptides, and companion diagnostic methods of identifying subjects for treatment. The peptides comprise T cell epitopes that are immunogenic in a high percentage of patients.",
