  MTD was defined as the dose level at which 1 out of 6 subjects or no one experienced a DLT.

  Up to 27 days

Secondary Outcomes (6)

• T1/2

  Measured on 0,1, 2, 4, 6, 8, 12, 24 and 48 hours in single-dosing stage and pre-administration of day 6, day 13, day 20 and 0, 2, 4, 6, 8,12 and 24 hours of Day27 in the multiple-dosing stage.

• ORR

  From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 4 months

• Expected survival time\>=12 weeks;
• Fertile men and women must agree to carry out birth control with effective methods for a period of 180 days from the signing of the informed consent form until the last administration of investigational drug. Fertile women include premenopausal women and women 2 years before menopause. Fertile women must have a negative pregnancy test within 7 days (including) before the first dose of the investigational drug;
• Subjects or their legal representatives are able to communicate well with the investigators and complete the study in accordance with protocol.
