Definitions
- Immunotherapy drugs containing di RNA as an active ingredient containing di RNA as an active ingredient
- the present invention relates to an immunotherapy drug comprising as an active ingredient a diRNA having a measles virus-derived RNA sequence, and a tumor immunotherapy composition comprising the diRNA and a cell wall skeleton of a Gram-positive bacterium.
- One of the cancer treatment methods is so-called cancer immunotherapy that induces cancer regression by enhancing the immunity of the patient's own cancer cells.
- the method of administering a peptide vaccine as a cancer antigen is the mainstream, but according to Rosenberg et al. (Non-Patent Document 1), the effectiveness of this method is said to be 2.5 ⁇ 1 ⁇ 2. .
- Patent Document 1 As a method for increasing the effective rate of this cancer immunotherapy, a method has been proposed in which an adjuvant that activates dendritic cells is simultaneously administered simultaneously with the administration of a cancer antigen (Patent Document 1).
- the adjuvant disclosed in Patent Document 1 is a cell wall skeleton (hereinafter referred to as BGG and GWS) of the gram-positive bacterium Mycobacterium mupovis Calmette and Guerin, and immature dendritic cells are matured dendritic cells.
- BGG and GWS cell wall skeleton
- immature dendritic cells are matured dendritic cells.
- GTL cytotoxic T lymphocytes
- BGG— GWS has the advantage of improving the 5-year survival rate by more than 10% by actually administering it to cancer patients and showing few side effects.
- BGG-GWS is a ligand that activates TLR (Toll Like Receptor) 2 and 4. This fact is based on the fact that BGG- GWS is an adjuvant that has neither the ability to induce type I interferon (referred to as type I interferon I FN-S) or the ability to enhance NK activity in human dendritic cells. Matches.
- GTL induced by single administration of BGG-GWS cannot kill cancers with low MHG class I protein expression levels. Therefore, although it has better anti-cancer effect than the peptide vaccine of Rosenberg et al. Is considered difficult.
- Patent Document 1 W001 / 048154
- Non-Patent Document 1 Rosenberg et al., Nat. Med., 2004, 10, 9, 909-92, p. 5
- the present invention provides an immunotherapeutic agent that exhibits a further excellent anticancer effect by using it instead of or at the same time as BGG-GWS, and particularly usable for immunotherapy of cancer. It is an object of the present invention to provide a substance exhibiting an immunostimulatory action useful for immunotherapy of cancer, particularly a substance that induces the production of IFNyS and / or enhances NK activity.
- the present inventors have surprisingly confirmed the presence of a substance having a desired activity in measles virus, particularly acclimated measles virus strain and measles virus vaccine strain, and the substance is diRNA. Ascertaining that it is (also called defective interference RNA, defective interfering, or loop RNA), the following inventions were completed.
- An immunotherapeutic agent comprising, as an active ingredient, diRNA having a measles virus-derived RNA sequence.
- the measles virus is an acclimated virus strain or a vaccine strain, (1) or (
- the immunotherapeutic agent according to 2).
- the acclimated virus strain is an Edmonston strain, a Nagahata strain, or an lchinose_V strain.
- diRNA comprising any RNA sequence represented by SEQ ID NOs: 9 to 15
- a composition for tumor immunotherapy comprising the immunotherapeutic agent according to any one of (1) to (7) and a cell wall skeleton of a Gram-positive bacterium.
- composition for tumor immunotherapy according to (8), wherein the cell wall skeleton of the Gram-positive bacterium is BGG-GWS.
- Medicament for promoting interferon expression and / or enhancing NK activity comprising diRNA having measles virus-derived RNA sequence as an active ingredient (1 1) Measles virus acclimatized The medicament according to (10), which is a virus strain or a vaccine strain.
- diR whose diRNA is composed of any RNA sequence shown in SEQ ID NOs: 9 to 15
- the immunotherapeutic agent of the present invention can enhance the immune defense power of chicks against foreign substances such as bacteria or neoplastic tumors such as cancer, and can be used as an anticancer agent or a tumor immunotherapeutic agent. is there. Furthermore, by using the immunotherapeutic agent of the present invention in combination with BGG-GWS, a pharmaceutical composition (tumor immunity therapeutic composition) effective for immunotherapy of cancer can be obtained.
- the diRNA according to the present invention does not show toxicity even when administered subcutaneously (100 ⁇ g) to mice and humans and can be a safe pharmaceutical.
- FIG. 1 is an electrophoretogram showing the detection results of diRNA of each measles virus strain.
- FIG. 2 shows a schematic diagram of p (+) MV Dl GFP plasmid.
- FIG. 3 shows a schematic diagram of diRNA-IGV-G.
- FIG. 4 shows the amount of fluorescence of luciferase from HEK cells into which di RNA-IGV-G has been introduced.
