Abstract

Described herein are certain crystalline forms of Compound 3, as well as pharmaceutical compositions employing the crystalline forms. Also provided are particles (e.g., nanoparticles) comprising such crystalline forms or pharmaceutical compositions. In certain examples, the particles are mucus penetrating particles (MPPs). The present invention further relates to methods of treating or preventing diseases using crystalline forms or pharmaceutical compositions.

Claims (10)

1. A method of inhibiting aberrant vascular endothelial growth factor (VEGF) signaling comprising administering to a subject in need thereof a therapeutically effective amount of crystalline form A of 7-(3-(4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxyquinazolin-7-yloxy)propyl)-2-oxa-7-azaspiro[3.5]nonane having an X-ray powder diffraction (XRPD) pattern with peaks at about 6.11±0.3, 9.63±0.3, 9.87±0.3, 11.10±0.3, 11.46±0.3, 12.26±0.3, 12.88±0.3, 14.40±0.3, 15.45±0.3, 15.66±0.3, 16.41±0.3, 17.54±0.3, 18.16±0.3, 18.60±0.3, 19.51±0.3, 20.36±0.3, 21.12±0.3, 21.14±0.3, 22.31±0.3, 23.01±0.3, 24.79±0.3, 25.71±0.3, 26.84±0.3, and 28.90±0.3 degrees two theta.

2. The method of claim 1 , wherein the crystalline form is administered topically, by injection, to the eye, orally, or by inhalation.

3. The method of claim 1 , wherein the inhibition of aberrant VEGF signaling treats an ocular disease.

4. The method of claim 3 , wherein the ocular disease is retinopathy, age-related macular degeneration, corneal neovascularization, diabetic macular edema, or retinal vein occlusion.

5. The method of claim 1 , wherein the aberrant signaling of VEGF is associated with cancer.

6. A method of inhibiting aberrant vascular endothelial growth factor (VEGF) signaling comprising administering to a subject in need thereof a therapeutically effective amount of crystalline form A of 7-(3-(4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxyquinazolin-7-yloxy)propyl)-2-oxa-7-azaspiro[3.5]nonane having an X-ray powder diffraction (XRPD) pattern with peaks at about 7.70±0.3, 13.53±0.3, 9.87±0.3, 10.69±0.3, 12.88±0.3, 14.40±0.3, 15.45±0.3, 16.42±0.3, 17.27±0.3, 18.44±0.3, 18.90±0.3, 19.73±0.3, 21.14±0.3, 22.56±0.3, 23.10±0.3, 26.07±0.3, 26.84±0.3, and 29.12±0.3 degrees two theta.

7. The method of claim 6 , wherein the crystalline form is administered topically, by injection, to the eye, orally, or by inhalation.

8. The method of claim 6 , wherein the inhibition of aberrant VEGF signaling treats an ocular disease.

9. The method of claim 3 , wherein the ocular disease is retinopathy, age-related macular degeneration, corneal neovascularization, diabetic macular edema, or retinal vein occlusion.

10. The method of claim 6 , wherein the aberrant signaling of VEGF is associated with cancer.
