- Conditions
- Advanced Solid Tumor
- Interventions
- Biological: KN052
- Registration Number
- NCT05309512
- Lead Sponsor
- Jiangsu Alphamab Biopharmaceuticals Co., Ltd
- Brief Summary
This is a phase Ia/Ib open, multicenter study of solid tumor subjects in China.Including dose increasing period and cohort expansion period.A BOIN design is used in the dose escalation phase,a total of 8 dose groups were designed.In the expansion phase of the cohort, 15 to 30 subjects will be enrolled in a specific tumor type (liver cancer, stomach cancer, kidney cancer, melanoma, urothelial carcinoma, and other tumors determined by the SMC).

Group Intervention Description KN052 single drug group KN052 The 8 dose groups in the dose increasing period were intravenous administration of 0.01mg/kg, 0.1mg/kg, 0.3mg/kg, 1mg/kg, 2mg/kg, 4mg/kg, 6mg/kg and 9mg/kg every two weeks, respectively. Based on the selected maximum tolerated dose of Q2W and in combination with the pharmacokinetic model, the sponsor would consider adding 1-2 Q3W treatment groups, with 6-12 patients in each dose group for DLT observation to explore the optimal dose regimen. The queue extension period is dose RP2D; Give it intravenously every two weeks or three weeks.
- Primary Outcome Measures
Name Time Method MTD（ Maximum tolerated Dose） Throughout the duration of the study，About 1 year MTD (Maximum tolerated Dose) is the dose for which the isotonic estimate of the toxicity rate is closest to the target toxicity rate based on the BOIN Design
ORR（Objective Response Rate) Throughout the duration of the study，About 1 year Objective response rate (ORR) was defined as the proportion of participants who achieve either complete response \[CR\] or partial response \[PR\] per Response Evaluation Criteria in Solid Tumors (RECIST v1.1）
DOR(Duration Of Response) Throughout the duration of the study，About 1 year Defined as the time from the first evaluation of objective response to the first evaluation of PD or death from any cause prior to PD
- Secondary Outcome Measures
Name Time Method Frequency of immunogenicity Throughout the duration of the study，About 1 year Frequency of occurrence of anti-KN052 antibody and neutralizing antibody
The probability of adverse events Throughout the duration of the study，About 1 year Including the occurrence probability of TESAE, TEAE, TRAE, irAE, IRR and AE above grade CTCAE 3
Cmax of KN052 Throughout the duration of the study，About 1 year Maximum observed serum concentration of KN052
AUC(0-T) for KN052 Throughout the duration of the study，About 1 year Adjusted geometric means of area under the serum concentration-time curve from time zero to the time of last quantifiable concentration (AUC(0-T)) for KN052
