CA3088185C — Suspension compositions of multi-target inhibitors

USPTO Abstract

This disclosure relates to aqueous suspension formulations of multi-target inhibitors. These formulations can be locally administered to target tissues such as eyes, prostate, that may be solved by the present disclosure are to (1) provide an injectable dosage form that allows direct delivery of a multi-target inhibitor to the proximity of the diseased tissue, (2) be compatible with the tissue of the site of administration, (3) form a drug reservoir at the administration site to allow prolonged supply of the drug to the diseased tissue, and thus reduce dosing frequency, (4) the release rate of the drug from the reservoir is such that above therapeutic level of the drug in the diseased tissue is achievable, (5) have physicochemical properties that are suitable for clinical uses, (6) be terminally sterilizable so that safety risk due to contamination of micro-organisms can be minimized, and (7) have a stability profile suitable for long term storage and distribution.
