First claim

Opening claim text (preview).

We claim: 1. A composition comprising nintedanib particles, wherein the nintedanib particles are at least 99% nintedanib by weight, or a pharmaceutically acceptable salt thereof, wherein the nintedanib particles have a specific surface area (SSA) of between 9 m 2 /g and about 20.14 m 2 /g, wherein the nintedanib particles are not bound to or conjugated to any other substance, and wherein the nintedanib particles have a volume-mean particle size between about 0.5 μm and about 5.0 μm. 2. The composition of claim 1 , wherein the nintedanib comprises nintedanib esylate. 3. The composition of claim 1 , wherein the composition is present in a suspension that further comprises a pharmaceutically acceptable aqueous carrier. 4. The composition of claim 1 , wherein the composition is a dry powder for inhalation. 5. The composition of claim 1 , wherein the nintedanib particles have a specific surface area (SSA) of between 9.94 m 2 /g and 20.14 m 2 /g. 6. The composition of claim 1 , wherein the nintedanib particles have a specific surface area between 11.05 m 2 /g and about 20.14 m 2 /g. 7. The composition of claim 1 , wherein the nintedanib particles are aerosolized and aerosol droplets of the nintedanib particles have a MMAD of between about 0.5 μm to about 6 μm diameter. 8. The composition of claim 6 , wherein the nintedanib particles are aerosolized and aerosol droplets of the nintedanib particles have a MMAD of between about 0.5 μm to about 6 μm diameter.
