Brief summary: The study will be conducted in about 51 participants in total. The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic profile and preliminary antitumor efficacy of Hemay181 in patients with advanced solid tumors.

Detailed description: The primary purpose of this study is to evaluate the safety and tolerability of Hemay181 in patients with advanced solid tumors, and to explore the maximum tolerated dose. The secondary purpose is to evaluate the pharmacokinetic profile of Hemay181 in patients with advanced solid tumors and to evaluate the preliminary evaluation of the anti-tumor efficacy of Hemay181.

The study will be conducted in two parts. Part one, trial will be conducted in about 24 subjects to determine safety and tolerability of Hemay181 in patients with advanced solid tumors. Part two, approximately 15-27 additional subjects with advanced solid tumors are included to better define the tolerability and preliminary efficacy of Hemay181.

Eligibility criteria: Inclusion Criteria:

1. Male or female subjects aged 18 to 65 years;
2. Subjects must give informed consent to the study before the study entry and voluntarily sign a written informed consent form;
3. Advanced solid tumors patients that confirmed by pathology (histology or cytology) with adequate standard therapy failure or currently have no effective standard treatment (such as breast, liver, lung, gastric cancer, colorectal cancer, etc.); Standard therapy failure is defined as: patients who have undergone at least 2 lines of standard antineoplastic therapy after recurrence/metastasis (including treatment-naïve stage IV) (if only 1-line therapy is recommended for the tumor, standard 1-line therapy shall prevail), and who have been confirmed by the investigator or have a clear disease progression or are intolerable by the medical history;

6. Have received drug therapy from other clinical trials within 4 weeks prior to enrollment;
7. Known allergy to the active ingredient or excipients of the test drug;
8. The investigator believes that the subject has any clinical or laboratory abnormalities and is not suitable to participate in this clinical study.
