Study Arms (3)
Phase Ib: Part1-Dose Escalation
EXPERIMENTALThis study will employ the traditional "3+3" dose escalation design. Ultimately, two combination dosing cohorts will be selected to enter Part 2, the dose expansion phase, based on a comprehensive evaluation of the safety and pharmacokinetic (PK) data obtained by the investigators and the sponsor.
Phase Ib: Part2-Dose Expansion
EXPERIMENTALThe safety and pharmacokinetic (PK) data obtained in Part 1 will be used to determine two expansion phase doses of the ZG006 and ZG005 combination. The dose expansion study will further evaluate the efficacy of the two selected combination dosing cohorts in patients with advanced small cell lung cancer and neuroendocrine carcinoma.
Phase II
EXPERIMENTALParticipants will receive the RP2D of ZG006 in combination with ZG005 identified in Phase Ib of the study.
