A First-in-Human, Phase 1 Study of JAB-3312 in Adult Patients With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
This is a Phase 1, first-in-human, 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.

Outcome Measures
Primary Outcome Measures
- Number of participants with dose limiting toxicities [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.
- Find Recommended Phase 2 Dose (RP2D) of JAB-3312 [Approximately 2 years]
Measurements of MTD (i.e. the highest dose of JAB-3312 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
- Number of participants with adverse events [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
- Area under the curve [Approximately 2 years]
Area under the plasma concentration time curve of JAB-3312
- Cmax [Approximately 2 years]
Highest observed plasma concentration of JAB-3312
- Tmax [Approximately 2 years]
Time of highest observed plasma concentration of JAB-3312
- T1/2 [Approximately 2 years]
Half life of JAB-3312
- Objective response rate ( ORR ) [Approximately 2 years]
ORR is defined as the proportion of participants with complete response or partial response (CR+PR)
- Duration of response ( DOR ) [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.
Eligibility Criteria
Criteria

-
Subjects experiencing unresolved Grade >1 toxicity before the start of treatment.
