Nanoparticles, controlled-release dosage forms, and methods for delivering an immunotherapeutic agent
The present disclosure relates to nanoparticles, controlled-release dosage forms, and methods for the administration of an immunotherapeutic agent.
1. A controlled-release pharmaceutical dosage form comprising:
a CpG oligodeoxynucleotide nano-cocoon, wherein the nano-cocoon comprises an immunotherapeutic agent and inflammation-responsive nanoparticles, wherein the nanoparticles encapsulate a restriction enzyme, wherein the inflammation-responsive nanoparticles comprise triglycerol monostearate (TGMS), and wherein the restriction enzyme is HhaI, and wherein the immunotherapeutic agent is selected from an anti-PD1 antibody, an anti-PDL1 antibody, an anti-CTLA4 antibody, or a combination thereof.
2. The dosage form of claim 1 , wherein the immunotherapeutic agent is an anti-PD1 antibody.
3. The dosage form of claim 2 , wherein the anti-PD1 antibody is nivolumab.
4. The dosage form of claim 2 , wherein the anti-PD1 antibody is pembrolizumab.
5. The dosage form of claim 1 , wherein the immunotherapeutic agent is an anti-CTLA4 antibody.
6. The dosage form of claim 5 , wherein the anti-CTLA4 antibody is ipilimumab.
7. The dosage form of claim 1 , wherein the immunotherapeutic agent is an anti-PD1 antibody in combination with an anti-CTLA4 antibody.
