Inclusion Criteria:
(1)Target subjects

2. Patients with various types of advanced solid tumors confirmed by cytological or
histological examination.
Dose escalation test phase: including breast cancer, colorectal cancer, neuroendocrine
tumors, etc .; Extended trial phase: limited to patients with HR + / HER2-,
triple-negative, breast, colorectal, and neuroendocrine tumors, and patients with HR +
/ HER2- and colorectal cancer need genetic testing (blood and / or tumor tissue)
PIK3CA mutations have been confirmed. Patients with triple negative breast cancer need
genetic testing (blood and / or tumor tissue) to confirm PIK3CA / PTEN- mutations.
3. Requires at least standard treatment failure or no standard treatment. Definition of
treatment failure: a. Disease progression during or after treatment must have clear
imaging or clinical evidence; b. Withdrawal from treatment due to intolerable
response.
4. According to the solid tumor evaluation criteria (RECIST 1.1), there is at least one
measurable lesion.
5. Relieve from previous chemotherapy, hormone therapy, targeted therapy, radiotherapy or
surgical treatment of toxic reactions (according to CTCAE v5.0 grading = 1 except hair
loss)
6. ECOG score is 0 or 1 (see Annex 2 for ECOG score criteria);
7. Expected survival time = 12 weeks;
(2) The subject must have proper organ function
1. Blood routine: absolute neutrophil (ANC) = 1.5 × 109 / L; platelet (PLT) = 75 × 109 /
L; hemoglobin (Hb) = 90 g / L; Have received hematopoietic cell colony-stimulating
growth factors (eg G-CSF, GM-CSF) or have not received blood transfusions.
Erythropoietin or erythropoietin therapy can be maintained if it is used immediately
before enrollment.
2. Liver function: ALT and AST = 2.5 × ULN (for patients with liver metastases, ALT and
AST can be relaxed to = 5.0 × ULN); serum bilirubin = 1.5 × ULN;
3. Renal function: serum creatinine = 1.5 × ULN; or creatinine clearance (CrCl) = 60 mL /
min calculated according to the Cockcroft-Gault formula:
Urine routine urinary protein = 1+; if urinary routine urinary protein = 2+, a 24-hour
urine protein quantification is less than 1 g.
4. Electrolyte: LLN = blood potassium = ULN;
5. Coagulation function: international standardized ratio (INR) = 1.5 × ULN; activated
partial thromboplastin time (APTT) = 1.5 × ULN; prothrombin time (PT) = 1.5 × ULN;
Exclusion Criteria:
(1) previous treatment history
1. Have previously been treated with PI3K inhibitors, mTOR inhibitors (such as
everolimus) or AKT inhibitors.
2. Patients who have received targeted therapy within 4 weeks before the first dose or =
5 × drug half-life (if the half-life of the drug is specified, it is calculated as 5
times the half-life, otherwise 4 weeks);
3. Patients who have received chemotherapy, hormonal antitumor therapy, immunotherapy or
major surgery within 4 weeks before the first dose.
Note: If the previous treatment was nitrosourea or mitomycin, the treatment must be
discontinued at least 6 weeks before the first study drug is administered.
4. Patients who have received radiation therapy within 4 weeks before the first dose.
5. Have received clinical trial drug treatment within 4 weeks before the first
medication, or are receiving other clinical trial drug treatment;
(2) History of disease and surgery
1. CNS metastases requiring current treatment or uncontrolled CNS metastases; or CNS
metastases confirmed but not stable for more than 4 weeks after treatment;
2. Patients with spinal cord compression, cancerous meningitis, or meningitis;
3. Currently diagnosed with type I or type II diabetes or fasting blood glucose levels>
6.7 mmol / L, or HbA1c> 7%;
4. Patients with hypertension controlled by two or more drugs, or uncontrolled
hypertension (systolic blood pressure> 140 mmHg or diastolic blood pressure> 90 mmHg);
5. Left ventricular ejection fraction (LVEF) <50%; QTcF> 450 ms for men, QTcF> 470 ms for
women (QTcF is calculated using Fridericia's correction formula QTcF = QT / RR 0.33);
any room with obvious clinical significance History of arrhythmia (such as ventricular
tachycardia, ventricular fibrillation, torsional ventricular tachycardia or frequent
ventricular premature beats, congenital prolonged QT interval syndrome).
6. Multiple factors affecting oral medication (eg, inability to swallow, chronic
diarrhea, and intestinal obstruction, etc.);
7. Patients with a clear tendency to gastrointestinal bleeding, including the following:
local active ulcer lesions and positive fecal occult blood; those with a history of
melena and vomiting within 2 months before the first medication; researchers believe
that digestion may occur Major bleeding
