Brief Summary:
APG-1252 is a highly potent Bcl-2 family protein inhibitor, a promising drug candidate which shown high binding affinities to Bcl-2, Bcl-xL and Bcl-w. The preclinical studies have shown that APG-1252 alone achieves complete and persistent tumor regression in multiple tumor xenograft models with a twice weekly or weekly dose-schedule, including SCLC, colon, breast and ALL cancer xenografts; achieves strong synergy with the chemotherapeutic agents, indicating that APG-1252 may have a broad therapeutic potential for the treatment of human cancer as a single agent and in combination with other classes of anticancer drugs. APG-1252 is intended for the treatment of patients with SCLC or other solid tumors. Upon completion of the Phase 1 dose escalation study to establish the maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), and/or recommended phase 2 dose (RP2D), several phase Ib/II studies will be implemented accordingly.

Arm Intervention/treatment
Experimental: APG-1252
The starting dose for this study was 40 mg and 1 patient would be enrolled at this dose level. The dose escalation will convert to a standard 3+3 design following the occurrence of DLT or two ≥ Grade 2 adverse event or at doses 80 mg.
Drug: APG-1252
Multiple dose cohorts, 30 minute IV infusion, twice weekly for 3 weeks of a cycle with 28 days.
Other Name: APG-1252 for injection

Primary Outcome Measures :
  1. Dose limit toxicity (DLT) determination [ Time Frame: 18-24 months ]
    Number of participants with APG-1252 treatment-related adverse events as assessed by CTCAE v4.03

  2. Maximum tolerated dose (MTD) determination [ Time Frame: 18-24 months ]
    If ≥ 2/6 patients develop a DLT at any dose level, then this dose will be declared as the MTD.

Secondary Outcome Measures :
  1. Pharmacokinetic evaluation [ Time Frame: 18-24 months ]
    Peak plasma concentration (Cmax) will be assessed on all participants with APG-1252 treatments.

  2. Preliminary efficacy assessment [ Time Frame: 18-24 months ]
    Patients will be evaluated for response every 2 cycles (i.e., 8 weeks), according to the new response evaluation criteria in solid tumors: revised RECIST Guideline, Version 1.1

Other Outcome Measures:
  1. Pharmacokinetic evaluation [ Time Frame: 18-24 months ]
    Area under the plasma concentration versus time curve (AUC) will be assessed on all participants with APG-1252 treatments

  2. Pharmacodynamic evaluation [ Time Frame: 18-24 months ]
    Apoptosis will be assessed on the patients treated with APG-1252

  8. Willingness to use contraception by a method that is deemed effective by the investigator by both males and female patients of child bearing potential (postmenopausal women must have been amenorrheal for at least 12 months to be considered of non-childbearing potential) and their partners throughout the treatment period and for at least three months following the last dose of study drug;
