INTERVENTIONAL
Conditions
Summary
The main purpose To evaluate the safety, tolerability, and pharmacokinetic characteristics of SIBP-A18 and determine the maximum tolerable dose (MTD) and phase II recommended dose (RP2D). A secondary purpose To preliminarily evaluate the anti-tumor efficacy of SIBP-A18. Evaluate the effect of SIBP-A18 injection on Q to T interval/Corrected QT interval (QT/QTc interval) in participants with advanced solid tumors

Interventions
SIBP-A18 formulation for injection, Claudin18.2-ADC. Strength: 1.0, 2.0, 3.2, 4.0, 4.8, 5.6, 6.4 and 8.0 mg/kg. Intravenous infusion administration, with a treatment cycle of every 21 days, administered once on the first day of each cycle. The dose escalation stage, 1mg/kg and 2mg/ kg were subjected to accelerated titration, where the safety was evaluated within 21 days after the first administration to one participant. If dose-limiting toxicity (DLT) occurred, the traditional "3+3" dose escalation method was immediately switched. If DLT does not occur, the next dose group will be explored. The third stage will use RP2D for further exploration.
