Brief summary: This is a Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Oral Dosing of CM082 tablets in Chinese Patients With Advanced Malignant Solid Tumors

Detailed description: This is a single-center、open-label and non-controlled Phase 1 study which will be conducted in two parts: part A is the dose-escalation phase; part B is dose-expansion phase. The dose-escalation phase is guided by pharmacokinetics (PK) and safety, according to the standard 3+3 dose-escalation schema. CM082 tablets are taken orally with a starting dose of 200 mg and a subsequent dose of 400, 600 and 800 mg. The way of administration is as follows: QD or BID. The primary objective of this study is to determine the maximum tolerable dose (MTD)、characteristics of dose-limited toxicity (DLT) and pharmacokinetics (PK). Secondary objectives include safety、tolerability and preliminary efficacy

Eligibility criteria: Inclusion Criteria:

* Age:≥18 years.
* BMI generally ranges from 18-28 (BMI=Weight (Kg)/Height (m)2)
* Patients with advanced malignant solid tumors confirmed by histological or cytological examination.
* According to Recist1.1 criteria, patients have measurable or assessable tumors, and patients with advanced malignant solid tumors who have failed to respond to previous standard treatment regimens, are unable to tolerate previous treatment regimens or lack effective treatment regimens.
* Organ function level must meet the following requirements (7 days before treatment):

  * Bone marrow: absolute neutrophil count (ANC)≥1.5\^109/L, platelet (PLT)≥100\^109/L, hemoglobin (HB)≥9g/dL (no blood transfusion or component blood received within 14 days before detection).
  * Liver: Serum bilirubin (TBIL) ≤1.5 \* upper limit of normal (ULN) , aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 \* ULN (If the patient's liver metastases, AST and ALT are allowed to be ≤ 5 \* ULN) ).
  * Serum creatinine≤1.5 \* ULN and endogenous creatinine clearance rate≥50mL/min. According to Cockcroft-Gault formula, Please refer to attachment 7 for details.
  * International normalized ratio (INR) and activated partial thromboplastin time (APTT)≤1.5 \* ULN (This provision applies only to patients who do not receive anticoagulant treatment; for patients receiving anticoagulant treatment, anticoagulants should be used within the treatment requirements).
  * Urine protein (UP)≤1+. If UP\>1+, 24-hour UP should be collected for determination, and the total amount of UP should be ≤1g.
  * FT3、FT4 and thyroid-stimulating hormone (TSH) are normal or abnormal without clinical significance（Except for advanced thyroid cancer）.
* No immunodeficiency.
* The damage causes by other treatments is restored to 1 grade (CTCAE version 4.03), except for hair loss and pigmentation; If the nutritional status is stable, the long-term toxicity that cannot be recovered is allowed to exist by the investigator'judgement.
* Expected survival time≥ 3 months.
* Eastern Cooperative Group (ECOG) Performance Status score of ≤1.
* The results of serum pregnancy test for women of childbearing age should be negative within 7 days before treatment.
* Men who are fertile or women who are likely to become pregnant must use highly effective contraceptive methods (e.g., oral contraceptives, intrauterine contraceptives, sex control or barrier contraceptives combined with spermicides ) throughout the trial and continue to use contraception for 12 months after the end of treatment.
* Patients can voluntarily sign written informed consent.

Exclusion Criteria:

-Within 4 weeks before the first use of the study drug, the patient received anti- tumor drug therapy such as chemotherapy, targeted therapy, radiotherapy, biological therapy or endocrine therapy, except for the following: Nitrous urea or mitomycin C were used within 6 weeks before the first use of the study drug; Oral fluorouracil and small molecular targeted drugs were used within 2 weeks before the first use of the study drug or within 5 half-lives (whichever is the longer); Chinese medicine with anti-cancer indications was used within 1 week before the first use of the study drug.

* Surgical treatment (except biopsy) was performed within 4 weeks before the first use of study drug.
* Patients who have participated in or are participating in any other drug/therapy clinical trial (including but not limited to the anti-tumor clinical trial) within 4 weeks before treatment, counting from the time of last administration of the last clinical trial.
