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
Full 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

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):
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.
Patients who received hematopoietic stimulating factors (e.g., granulocyte colony stimulating factor (G-CSF), erythropoietin, etc.) within one week before treatment.
Pleural or ascites with clinical symptoms and requiring symptomatic treatment.
Patients with active pulmonary disease, interstitial pneumonia or pulmonary fibrosis.
Having any uncontrollable clinical problems or associated risk factors, including but not limited to:
Poorly controlled hypertension (blood pressure persistently greater than 150/90 mmHg).
Left ventricular ejection fraction (LVEF)≤50%.
The QT interval of heart rate correction (QTc) > 450 msec (males) or 460 msec (females) ( Bazett's correction (QTcB)=QT/(RR^0.5)).
Patients have a clinically significant history of arrhythmia or current evidence of arrhythmia, but control of atrial fibrillation for more than 30 days before administration does not affect inclusion.
Patients implanted with cardiac defibrillator.
Poorly controlled diabetes [(fasting blood glucose should not be greater than 8.9 mmol/L after drug control) refer to CTCAE version 4.03-grade 1 of hyperglycemia].
Heart disease (Class III/IV congestive heart failure or cardiac block defined by the New York Heart Association).
Decompensated cirrhosis.
The following conditions occur within 6 months before treatment:
Patients have not yet fully recovered from previous operations.
Patients who have taken strong inhibitors and inducers of CYP3A hepatic metabolic enzymes within 2 weeks before treatment.
Patients also take drugs that are at risk of prolonging QTc and/or Tdp.
Patients with a history of allergy to CM082 similar drugs (e.g., sunitinib, sorafenib, pazopanib, etc.).
Pregnant or lactating women.
Women/men with fertility who refuse to use contraception during the trial.
Any uncontrollable clinical problem (such as serious mental, neurological, cardiovascular, respiratory and other system diseases) or active infection that significantly affects clinical trials.
The patient has clinical symptoms or uncontrolled central nervous system metastasis or meningeal metastasis, which is judged by the investigator to be unsuitable for admission;
Patients with active upper gastrointestinal ulcer or other diseases known to affect drug absorption, distribution, metabolism or clearance.
Patients with obvious abnormal gastrointestinal function such as vomiting、 diarrhea, etc..
Positive results of HIV or Treponema pallidum antibodies (Acceptance of Treponema pallidum antibody titer test results in a Class III Grade I hospital including research centers).
Patients with active hepatitis B or C：
Patients who have progressed after using a receptor tyrosine kinase inhibitor that targets VEGFR.
Investigators consider that it is not appropriate for subjects to participate in this study from the perspective of clinical treatment.
