Trial outcomes
Primary outcomes
Maximum tolerated dose (MTD)
MTD is defined as the maximum dose level at which ≤1 patient have dose limiting toxicities (DLTs) during the DLT observation period, and it should be determined with 6 evaluable patients.
Number of participants with Dose Limiting Toxicities (DLTs)
Severity of adverse events as assessed by the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) v5.0.
Number of participants experiencing adverse events (AEs)/serious adverse events (SAEs)
Number of participants with incidence of adverse events and with serious adverse events including changes from baseline in laboratory parameters, vital signs, Electrocardiogram (ECG), and physical examination, etc.
Secondary outcomes
Pharmacokinetic (PK) parameters
To characterize the PK Peak Plasma Concentration (Cmax) of SYN608 monotherapy
Pharmacokinetic (PK) parameters
To characterize the PK Time to Peak drug Concentration (Tmax) of SYN608 monotherapy
Pharmacokinetic (PK) parameters
