Method of treating infusion reaction with lipid formulated therapeutic agent
A recently granted patent (Publication Number: US11904052B2) discloses a method for ameliorating infusion reactions associated with the intravenous administration of lipid-formulated therapeutic agents in mammals. The method involves administering a nonsteroidal anti-inflammatory drug (NSAID), specifically ketorolac, in combination with the lipid-formulated therapeutic agent. The lipid formulation includes a nucleic acid, polypeptide, or organic compound formulated in a lipid nanoparticle (LNP) containing a cationic lipid and a non-cationic lipid. The infusion reactions targeted by this method include hypertension, hypotension, and an increase in plasma thromboxane B2 levels.
The administration of the NSAID, ketorolac, typically begins within about 2 hours prior to the intravenous administration of the lipid-formulated therapeutic agent. The dosage of ketorolac administered ranges from about 15 mg to 60 mg, with a preferred range of 30 mg to 60 mg. Additionally, the lipid-formulated therapeutic agent can be an antibody, siRNA, or mRNA, with specific mention of siRNA and mRNA in the claims. The method also allows for the administration of additional therapeutic agents, such as dexamethasone, to further enhance the amelioration of infusion reactions. The NSAID can be administered parenterally, intravenously, intramuscularly, or subcutaneously, providing flexibility in the delivery of the treatment regimen.
