Patent Claims:	1. A method of treating HR+ breast cancer in a human, comprising administering to the human an effective amount of Compound A1, or a pharmaceutically acceptable salt thereof: and an aromatase inhibitor, wherein the aromatase inhibitor is letrozole or anastrozole. 2. The method of claim 1, wherein the aromatase inhibitor is letrozole. 3. The method of claim 1, wherein the aromatase inhibitor is anastrozole. 4. The method of claim 1, wherein a jointly therapeutically effective amount of Compound A1, or a pharmaceutically acceptable salt thereof, and aromatase inhibitor is administered, and the administration provides to the human 200 mg/day, 400 mg/day or 600 mg/day of Compound A1. 5. The method of claim 4, wherein the administration provides to the human 600 mg/day of Compound A1. 6. The method of claim 5, wherein the aromatase inhibitor is letrozole. 7. The method of claim 5, wherein the aromatase inhibitor is anastrozole. 8. The method of claim 4, wherein the administration provides to the human 400 mg/day of Compound A1. 9. The method of claim 8, wherein the aromatase inhibitor is letrozole. 10. The method of claim 8, wherein the aromatase inhibitor is anastrozole. 11. The method of claim 4, wherein the administration provides to the human 200 mg/day of Compound A1. 12. The method of claim 11, wherein the aromatase inhibitor is letrozole. 13. The method of claim 11, wherein the aromatase inhibitor is anastrozole. 14. A method of administering Compound A1, or a pharmaceutically acceptable salt thereof: and an aromatase inhibitor to a human HR+breast cancer patient, the method comprising administering Compound A1 and the aromatase inhibitor to the patient to provide therapeutically effective levels of Compound A1 and the aromatase inhibitor in the patient, wherein the aromatase inhibitor is letrozole or anastrozole. 15. The method of claim 14, wherein the aromatase inhibitor is letrozole. 16. The method of claim 14, wherein the aromatase inhibitor is anastrozole. 17. The method of claim 14, wherein the administration provides to the human 200 mg/day, 400 mg/day or 600 mg/day of Compound A1. 18. The method of claim 17, wherein the administration provides to the human 600 mg/day of Compound A1. 19. The method of claim 18, wherein the aromatase inhibitor is letrozole. 20. The method of claim 18, wherein the aromatase inhibitor is anastrozole. 21. The method of claim 17, wherein the administration provides to the human 400 mg/day of Compound A1. 22. The method of claim 21, wherein the aromatase inhibitor is letrozole. 23. The method of claim 21, wherein the aromatase inhibitor is anastrozole. 24. The method of claim 17, wherein the administration provides to the human 200 mg/day of Compound A1. 25. The method of claim 24, wherein the aromatase inhibitor is letrozole. 26. The method of claim 24, wherein the aromatase inhibitor is anastrozole.
