A Phase 1 Study of CX1003 (Kanitinib) in Patients With Advanced Solid Tumors
Study Details
Study Description
Brief Summary
CX1003 is a novel multi-target tyrosine kinase inhibitor that is designed to primarily inhibit vascular endothelial growth factor receptor 2 (VEGFR2) and hepatocyte growth factor receptor (HGFR/MET). This study aimed to evaluate the safety, pharmacokinetics, and antitumor activity of CX1003 in patients with refractory advanced or metastatic solid tumors.

Outcome Measures
Primary Outcome Measures
- Incidence of dose-limiting toxicities (DLTs) by NCI CTCAE 5.0: Dose Escalation Stage [First 5 weeks after initial administration of CX1003]
Occurrence of any of the following toxicities was considered DLT if judged by the Investigator to be possibly, probably, or definitely related to the administration of CX1003: Any Grade 3 or higher non-hematologic toxicity (including persisting nausea, vomiting, diarrhea, and electrolyte imbalances despite optimal medical management); Grade 4 neutropenia for >5 consecutive days; Grade 3 or higher febrile neutropenia; Grade 3 or higher neutropenia associated with infection; Grade 4 thrombocytopenia; Grade 3 or higher thrombocytopenia with clinically significant bleeding or that requires a platelet transfusion.
- Maximum tolerated dose (MTD): Dose Escalation Stage [First 5 weeks after initial administration of CX1003]
The maximum tolerated dose (MTD) was defined as the highest dose for a given schedule that was expected to cause DLTs in no more than 33% of patients.
Secondary Outcome Measures
- Pharmacokinetics (PK) profile: Cmax [First 5 weeks after initial administration of CX1003]
Parameters: Peak Plasma Concentration (Cmax)
- Pharmacokinetics (PK) profile: Tmax [First 5 weeks after initial administration of CX1003]
Parameters: Time to reach the maximum plasma concentration (Tmax)
- Pharmacokinetics (PK) profile: T1/2 [First 5 weeks after initial administration of CX1003]
Parameters: Terminal half-life (T1/2)
- Pharmacokinetics (PK) profile: AUC [First 5 weeks after initial administration of CX1003]
Parameters: Area under the plasma concentration versus time curve (AUC)
- Pharmacokinetics (PK) profile: CL/F [First 5 weeks after initial administration of CX1003]
Parameters: Apparent body clearence from plasma (CL/F)
- Pharmacokinetics (PK) profile: Vz/F [First 5 weeks after initial administration of CX1003]
Parameters: Apparent volume of distribution (Vz/F)
- Objective Response Rate (ORR) [up to 24 months]
Overall response rate (ORR) was defined as the percentage of participants with a best overall complete response (CR) or partial response (PR) per RECIST 1.1.
- Progression-free survival (PFS) [up to 24 months]
Progression-free survival (PFS) was defined as the time from the start date of study drug to the date of the first radiologically documented progressive disease (PD) per RECIST 1.1 or death due to any cause.
- Disease Control Rate (DCR) [up to 24 months]
Disease Control Rate (DCR) was defined as the percentage of participants with a best overall complete response (CR), partial response (PR), or stable disease (SD) per RECIST 1.1.
- Duration of Response (DOR) [up to 24 months]
Duration of response (DOR) was defined as the time from first documented response (partial response (PR) or complete response (CR)) to the date of first documented disease progression (PD) or death due to any cause, among patients with a confirmed PR or CR per RECIST 1.1.
- Safety profile as assessed by the incidence, duration, and severity of adverse events [From first dose of CX1003 to 30 days after last dose]
Incidence, duration, and severity of AEs measured by laboratory assessments and physical findings according to NCI CTCAE 5.0.
