The invention claimed is: 1. A method of inhibiting the histone methyltransferase activity of EZH2 in a subject in need thereof comprising administering to the subject an effective amount of a solid crystalline form of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(ethyl (tetrahydro-2H-pyran-4-yl)amino)-4-methyl-4′-(morpholinomethyl)-[1,1′-biphenyl]-3-carboxamide hydrobromide, wherein the solid crystalline form exhibits an X-ray powder diffraction pattern having one or more characteristic peaks expressed in degrees 2-theta at about 3.9+/−0.3 degrees, about 17.5+/−0.3 degrees, and about 22.0+/−0.3 degrees 2-theta. 2. A method of inhibiting the histone methyltransferase activity of EZH2 in vitro comprising administering a solid crystalline form of N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(ethyl (tetrahydro-2H-pyran-4-yl)amino)-4-methyl-4′-(morpholinomethyl)-[1,1′-biphenyl]-3-carboxamide hydrobromide, wherein the solid crystalline form exhibits an X-ray powder diffraction pattern having one or more characteristic peaks expressed in degrees 2-theta at about 3.9+/−0.3 degrees, about 17.5+/−0.3 degrees, and about 22.0+/−0.3 degrees 2-theta. 3. The method of claim 1 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having one or more characteristic peaks expressed in degrees 2-theta selected from peaks at about 3.9+/−0.3 degrees, about 14.3+/−0.3 degrees, about 18.7+/−0.3 degrees, about 23.3+/−0.3 degrees, and about 23.6+/−0.3 degrees 2-theta. 4. The method of claim 1 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having at least 5 characteristic peaks expressed in degrees 2-theta at about 3.9+/−0.3 degrees, 10.1+/−0.3 degrees, 14.3+/−0.3 degrees, 17.5+/−0.3 degrees, 18.7+/−0.3 degrees, 20.6+/−0.3 degrees, 20.9+/−0.3 degrees, 21.8+/−0.3 degrees, 22.0+/−0.3 degrees, 23.3+/−0.3 degrees and 23.6+/−0.3 degrees 2-theta. 5. The method of claim 1 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having at least 6 characteristic peaks expressed in degrees 2-theta selected from peaks at about 3.9+/−0.3 degrees, 10.1+/−0.3 degrees, 14.3+/−0.3 degrees, 17.5+/−0.3 degrees, 18.7+/−0.3 degrees, 20.6+/−0.3 degrees, 20.9+/−0.3 degrees, 21.8+/−0.3 degrees, 22.0+/−0.3 degrees, 23.3+/−0.3 degrees and 23.6+/−0.3 degrees 2-theta. 6. The method of claim 1 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern substantially in accordance with FIG. 1 . 7. The method of claim 1 , wherein said solid crystalline form exhibits a differential scanning calorimetry thermogram having a characteristic peak expressed in units of ° C. at a temperature of 255+/−5° C. 8. The method of claim 1 , wherein said solid crystalline form exhibits a differential scanning calorimetry thermogram substantially in accordance with FIG. 3 . 9. The method of claim 1 , wherein said solid crystalline form is substantially free of impurities. 10. The method of claim 1 , wherein said solid crystalline form is substantially free of amorphous N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-5-(ethyl(tetrahydro-2H-pyran-4-yl)amino)-4-methyl-4′-(morpholinomethyl)-[1,1′-biphenyl]-3-carboxamide hydrobromide. 11. The method of claim 2 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having one or more characteristic peaks expressed in degrees 2-theta selected from peaks at about 3.9+/−0.3 degrees, about 14.3+/−0.3 degrees, about 18.7+/−0.3 degrees, about 23.3+/−0.3 degrees, and about 23.6+/−0.3 degrees 2-theta. 12. The method of claim 2 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having at least 5 characteristic peaks expressed in degrees 2-theta at about 3.9+/−0.3 degrees, 10.1+/−0.3 degrees, 14.3+/−0.3 degrees, 17.5+/−0.3 degrees, 18.7+/−0.3 degrees, 20.6+/−0.3 degrees, 20.9+/−0.3 degrees, 21.8+/−0.3 degrees, 22.0+/−0.3 degrees, 23.3+/−0.3 degrees and 23.6+/−0.3 degrees 2-theta. 13. The method of claim 2 , wherein said solid crystalline form exhibits an X-ray powder diffraction pattern having at least 6 characteristic peaks expressed in degrees 2-theta selected from peaks at about 3.9+/−0.3 degrees, 10.1+/−0.3 degrees, 14.3+/−0.3 degrees, 17.5+/−0.3 degrees, 18.7+/−0.3 degrees, 20.6+/−0.3 degrees, 20.9+/−0.3 degrees, 21.8+/−0.3 degrees, 22.0+/−0.3 degrees, 23.3+/−0.3 degrees and 23.6+/−0.3 degrees 2-theta. 14.
