Summary

The purpose of this study is to evaluate the safety and tolerability of Hemay022 combined with endocrine therapy in the treatment of ER and HER2-positive metastatic or advanced breast cancer, and to establish OTR (best tolerated regimen). The second purpose of this study is to evaluate the pharmacokinetics and efficacy of Hemay022 in combination with exemestane, and the safety of Hemay022 in combination with letrozole or fulvestrant.

The research will be divided into two parts. In the first part, 15 to 24 subjects will be enrolled to determine the safety and tolerability of combining Hemay022 with exemestane in patients with HER2-positive advanced breast cancer. The second part will enroll about 24-36 other subjects with ER and HER2-positive advanced breast cancer to better determine the tolerability and preliminary efficacy of Hemay022.

Therefore, for this part of the subjects, the expansion period is included " Post-menopausal female subjects who are suitable for letrozole or fulvestrant as endocrine therapy
Postmenopausal is defined as meeting any one of the following four conditions

Patients younger than 60 years old who are taking tamoxifen or toremifene, their FSH and estradiol levels are within the postmenopausal range (use the reference range of the local laboratory); Remarks: Premenopausal or perimenopausal women who do not meet the above-mentioned menopausal criteria can also be included in this study, but they must also receive zoladex ovarian suppression therapy. Ovarian suppression therapy has been started at least 14 days before the start of this program, and Must be continued during the treatment plan; For subjects whose postmenopausal status is difficult to judge, the investigator and medical personnel of the sponsor will determine whether to enter the group after discussion
