This is a Phase 1 dose escalation study to evaluate the safety, tolerability, pharmacokinetics, efficacy and preliminary food effect of BB3008 as monotherapy in subjects with advanced solid tumors.
This first-in-human (FIH) study of BB3008 will evaluate safety, tolerability, pharmacokinetics (PK) efficacy and preliminary food effect of BB3008 in subjects with advanced solid tumors. The primary objective is to determine the maximum tolerated dose (MTD) and the recommended phase II dose (RP2D) of BB3008 as monotherapy, and to evaluate the safety and tolerability of BB3008. The secondary objectives include the assessments of PK profile, preliminary efficacy, preliminary food effect (FE) and preliminary metabolites identification of BB3008. The exploratory objectives are to explore biomarkers and C-QTcF analysis.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| BB3008 monotherapy | Experimental | The study is composed of fasted dose cohorts and fed dose cohort. BB3008 will be administered orally daily alone as monotherapy in all cohorts. In the fasted dose cohorts, the subjects will receive once daily of BB3008 monotherapy fasted across approximately 6 ascending dose levels. The starting dose is 80 mg/day. In the fed dose cohort, the subjects will receive once daily of BB3008 monotherapy in a fed condition. The dose selected for fed dose cohort must be deemed safe as assessed by safety monitoring committee (SMC). |
