Application Number:	16/366,368
Patent Claims:	1. A method of treating a cancer in a patient in need thereof, wherein the cancer exhibits one or more chromosome translocations or inversions resulting in one or more NTRK1, NTRK2, or NTRK3 gene fusions, the method comprising administering to the patient a therapeutically effective amount of a crystalline form (I--HS) having the formula ##STR00007## wherein the crystalline form is characterized by having an X-ray powder diffraction pattern comprising peaks at .degree. 20 values of 18.4.+-.0.2, 20.7.+-.0.2, 23.1.+-.0.2, and 24.0.+-.0.2, wherein the cancer is selected from the group consisting of: lung cancer, undifferentiated sarcoma, acute myeloid leukemia, and colorectal cancer. 2. The method of claim 1, wherein the crystalline form is further characterized by having an X-ray powder diffraction pattern comprising a peak at a .degree.20 value of 10.7.+-.0.2. 3. The method of claim 1, wherein the crystalline form is further characterized by having an X-ray powder diffraction pattern comprising peaks at .degree.20 values of 10.7.+-.0.2, 19.2.+-.0.2, 20.2.+-.0.2, and 21.5.+-.0.2. 4. The method of claim 1, wherein the crystalline form is further characterized by having an X-ray powder diffraction pattern comprising peaks at .degree.20 values of 10.7.+-.0.2, 15.3.+-.0.2, 16.5.+-.0.2, 19.2.+-.0.2, 19.9.+-.0.2, 20.2.+-.0.2, 21.5.+-.0.2, 22.1.+-.0.2, 24.4.+-.0.2, 25.6.+-.0.2, 26.5.+-.0.2, 27.6.+-.0.2, 28.2.+-.0.2, 28.7.+-.0.2, 30.8.+-.0.2, and 38.5.+-.0.2. 5. The method of claim 1, wherein the one or more chromosome translocations or inversions results in the translation of a Trk fusion protein. 6. The method of claim 5, wherein the Trk fusion protein contains residues from a non-TrkA partner protein and TrkA. 7. The method of claim 6, wherein the Trk fusion protein is selected from the group consisting of: TP53-TrkA, LMNA-TrkA, CD74-TrkA, TFG-TrkA, TPM3-TrkA, NFASC-TrkA, BCAN-TrkA, MPRIP-TrkA, TPR-TrkA, RFWD2-TrkA, IRF2BP2-TrkA, SQSTM1-TrkA, SSBP2-TrkA, RABGAP1L-TrkA, C18ORF8-TrkA, RNF213-TrkA, TBC1D22A-TrkA, C20ORF112-TrkA, DNER-TrkA, ARHGEF2-TrkA, CHTOP-TrkA, PPL-TrkA, PLEKHA6-TrkA, PEAR1-TrkA, MRPL24-TrkA, MDM4-TrkA, LRRC71-TrkA, GRIPAP1-TrkA, EPS15-TrkA, DYNC2H1-TrkA, CEL-TrkA, EPHB2-TrkA, and TGF-TrkA. 8. The method of claim 5, wherein the Trk fusion protein contains residues from a non-TrkB partner protein and TrkB. 9. The method of claim 8, wherein the Trk fusion protein is selected from the group consisting of: NACC2-TrkB, QKI-TrkB, AFAP1-TrkB, PAN3-TrkB, SQSTM1-TrkB, TRIM24-TrkB, VCL-TrkB, AGBL4-TrkB, and DAB2IP-TrkB. 10. The method of claim 5, wherein the Trk fusion protein contains residues from a non-TrkC partner protein and TrkC. 11. The method of claim 10, wherein the Trk fusion protein is selected from the group consisting of: ETV6-TrkC, BTBD1-TrkC, LYN-TrkC, RBPMS-TrkC, EML4-TrkC, HOMER2-TrkC, TFG-TrkC, FAT1-TrkC, and TEL-TrkC. 12. The method of claim 1, wherein the cancer is lung cancer. 13. The method of claim 1, wherein the cancer is colorectal cancer. 14. The method of claim 1, wherein the cancer is undifferentiated sarcoma. 15. The method of claim 1, wherein the cancer is acute myeloid leukemia.
