Detailed Description
This is a single center, open-label, dose increasing study to evaluate the safety, tolerability, pharmacokinetic(PK) profile, and antitumor efficacy of KL340399 intratumoral in patients with advanced solid tumors.The dose increasing method of "BLRM" is used to explore the safety, tolerance and determine the maximum tolerated dose(MTD).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of subjects achieving Dose-limiting toxicity (DLT)
Time Frame: From data of initial dose until up to 21 days for treatment
|
DLT is defined as an adverse event (AE) that meets protocol defined DLT criteria during cycle 1 and is at least possibly related to study drug.
|
From data of initial dose until up to 21 days for treatment
|
Maximum Tolerated Dose (MTD)
Time Frame: From data of initial dose until up to 21 days for treatment
|
The maximum tolerated dose (MTD) is refers to the highest dose at which the patient's DLT incidence exceeding 33% during the first cycle.
|
From data of initial dose until up to 21 days for treatment
|
Incidence of Adverse Events [Safety and Tolerability]
Time Frame: Up to 24 months
|
Incidence of adverse events of KL340399 as a monotherapy as determined by patient reporting, clinical laboratory test changes from baseline, and clinically significant changes in physical examination data.
|
Up to 24 months
|
Recommended Phase 2 Dose (RP2D)
Time Frame: Up to 24 months
|
The recommended phase 2 dose (RP2D) will be based on a consideration of the totality of data including but not limited to safety data (including DLTs), PK, PD and preliminary efficacy, as available.
|
Up to 24 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|

Time Frame: Up to 24 months
|
The sum of the number of cases with Complete Response (CR) and Partial Response (PR) in all treated tumor patients (CR + PR) divided by the total number of cases.
|
Up to 24 months
|
Progression Free Survival (PFS)
Time Frame: Up to 24 months
|
PFS: Time from start of treatment to progression of disease (PD) or death, whichever occurs first, in patients with tumors.
|
Up to 24 months
|
Duration of Response (DOR)
Time Frame: Up to 24 months
|
DOR: Time from the start of the first assessment of CR or PR in tumor patients to PD or death due to any reason.
|
Up to 24 months
|
Overall Survival (OS)
Time Frame: Up to 24 months
|
OS: Time from start of treatment to death due to any reason.
|
Up to 24 months
