Brief Summary:
This is a Phase 1, open-label dose-escalation study to determine the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) and assess the DLT of JAB-3312. It is anticipated that approximately 24 subjects will be enrolled in the dose-escalation phase of the study. JAB-3312 will be administered orally once daily (QD) in 21-day treatment cycles.

Arm Intervention/treatment
Experimental: JAB-3312

Primary Outcome Measures :
  1. Number of participants with dose limiting toxicities [ Time Frame: Approximately 2 years ]
    Incidence of dose limiting toxicities (DLTs) in the dose escalation phase. A DLT is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the first treatment cycle with JAB-3312.

  2. Find Recommended Phase 2 Dose (RP2D) of JAB-3312 [ Time Frame: Approximately 2 years ]
    Measurements of MTD (i.e. the highest dose of JAB-3068 associated with the occurrence of Dose Limiting Toxicities (DLTs) in <33% of patients) or the RP2D (i.e. the highest tested dose that is declared safe and tolerable by the Investigators and Sponsor)


Secondary Outcome Measures :
  1. Number of participants with adverse events [ Time Frame: Approximately 2 years ]
    All patients participating in this study will be assessed for incidence and severity of adverse events (AEs) and serious AEs, including changes in laboratory values, vital signs, electrocardiograms, cardiac imaging and ophthalmological assessments

  2. Area under the curve [ Time Frame: Approximately 2 years ]
    Area under the plasma concentration time curve of JAB-3312

  3. Cmax [ Time Frame: Approximately 2 years ]
    Highest observed plasma concentration of JAB-3312

  4. Tmax [ Time Frame: Time of highest observed plasma concentration of JAB-3312 ]
    Time of highest observed plasma concentration of JAB-3312

  5. T1/2 [ Time Frame: Approximately 2 years ]
    Half life of JAB-3312

  6. Objective response rate ( ORR ) [ Time Frame: Approximately 2 years ]
    ORR is defined as the proportion of participants with complete response or partial response (CR+PR)

  7. Duration of response ( DOR ) [ Time Frame: Approximately 2 years ]
    DOR is defined as the time from the participant's initial objective response (CR or PR) to study drug therapy, to disease progression or death due to any cause, whichever occurs first.
