mRNA treatment nanoparticles
Provided herein are examples of mRNA treatment nanoparticles and methods of using them to treat a patient. An mRNA treatment nanoparticle may include one or more mRNAs encoding a tumor-specific antigen and an immunomodulatory agent; and a delivery vehicle molecule encapsulating the one or more mRNAs.
1. A therapeutic mRNA composition comprising:
a first mRNA scaffold comprising a first mRNA coding region encoding HPV16 E6 E7;
a second mRNA scaffold comprising a second mRNA coding region encoding an interleukin-12 (IL-12), wherein the IL-12 comprises the amino acid sequence of SEQ ID NO: 6; and
a third mRNA scaffold comprising a third mRNA coding region encoding a tumor necrosis factor superfamily member 14 (TNFSF14), wherein the TNFSF14 comprises the amino acid of SEQ ID NO:12, and
wherein the first mRNA scaffold, the second mRNA scaffold, and the third mRNA scaffold are encapsulated in a delivery vehicle; and
wherein the delivery vehicle is selected from the group consisting of lipid nanoparticles, polymer-based nanoparticles, cationic lipids, ionizable lipids, amino-lipidated peptoids, amphipathic molecules/nanoparticles, and tertiary amino lipidated cationic peptoids.
2. The therapeutic mRNA composition of claim 1 , wherein the first mRNA scaffold and the second mRNA scaffold are encapsulated in a single delivery vehicle.
3. The therapeutic mRNA composition of claim 1 , wherein the first mRNA scaffold, the second mRNA scaffold, and the third mRNA scaffold are encapsulated in a single delivery vehicle.
4. The therapeutic mRNA composition of claim 1 , wherein the TNFSF14 is wild type TNFSF14.
5. The therapeutic mRNA composition of claim 1 , wherein the therapeutic mRNA composition is an mRNA nanoparticle, an mRNA treatment nanoparticle, or a vaccine.
6. The therapeutic mRNA composition of claim 1 , wherein the therapeutic mRNA composition is configured to be administered to a subject known to have cervical cancer.
7. The composition of claim 1 , wherein the therapeutic mRNA composition is configured to be injected intratumorally.
