About
This is a multi-center, open-label, phase Ib/II study of APG-2575 as a single agent in patients with advanced solid tumors or in combination with anti-cancer agents such as CDK 4/6 inhibitor palbociclib in patients with ER+/HER2- metastatic breast cancer (mBC) who have progressed or relapsed after first line therapy
Full description
The phase Ⅰb is dose escalation of APG-2575 as a single agent or in combination with palbociclib. A standard 3+3 design will be used to determine the MTD of APG-2575 as single agent in patients with solid tumors and MTD and RP2D of APG-2575 in combination with palbociclib in patients with breast cancer (MTD-combo). The phase II portion is a signal seeking expansion of APG-2575 at RP2D in combination with palbociclib in patients with ER+/HER2- metastatic breast cancers who have progressed during or relapsed after CDK 4/6inhibitor therapy. The phase Ⅱ portion will be conducted based on Simon's Minimax two stage design.

Inclusion criteria
Age ≥ 18 years. 2. Histologically or cytologically confirmed solid tumors; These locally advanced or metastatic diseases have no standard effective therapy available as judged by the investigator. 3. For the patients with breast cancer:
Must have histological or cytological confirmation of metastatic carcinoma of the breast (either from the primary or metastatic site), with the following tumor molecular characteristics (as determined from pre-screening testing):
Must have been treated with CDK4/6 inhibitor in the metastatic setting. And the patients must have experienced disease progression during or recurrence after CDK4/6 inhibitor therapy, which must have been administered for a minimum of 8 weeks prior to progression.
Must have measurable disease (according to RECIST v1.1) or evaluable disease. Boneonly metastases are allowed.
Physiological postmenopausal, defined as:
L. Note: Use of growth-factors to maintain ANC criterion is not permitted 3) Platelet count ≥ 100 x 109
L. Note: Use of transfusions or thrombopoietic agents to achieve baseline platelet count criterion is prohibited. 4) ALT and AST ≤ 3 x upper limit of normal (ULN), or ≤ 5 x ULN if liver metastases are present. 5) Total serum bilirubin ≤ 1.5 x ULN. Patient's with Gilbert's syndrome may have a total serum bilirubin > 1.5 x ULN. 6) Serum creatinine ≤ 1.5 x upper limit of normal (ULN); if serum creatinine is >1.5 X ULN, creatinine clearance must be ≥ 50 mL/min (Cockcroft-Gault). 6. Female patients with childbearing potential must have negative urine or serum pregnancy test within 14 days prior to registration. 7. Able to swallow whole tablets. 8. Willingness to use contraception that is deemed effective for the patients with child bearing potential (postmenopausal women must have been amenorrhea for at least 12 months to be considered of non-childbearing potential) and their partners throughout the treatment period and for at least three months following the last dose of study drug.
