Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this multi-center, open, dose-increasing, dose-expanding Phase I clinical study, rapid titration and a "3+3" dose-increasing design were used to explore the safety, tolerability and PK characteristics of BAT8008 for injection in patients with advanced solid tumors. During the dose-escalation test, appropriate doses were selected for the extended study according to the previous study data.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Dose limiting toxicity (DLT)
Time Frame: At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)
DLT was defined as grade 3 or higher toxicity associated with the investigational product that occurred within 21 days of the subject's initial administration
At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)
Maximum tolerated dose (MTD)
Time Frame: At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)
MTD was defined as exploration in a dose group observed ≤1/6 of subjects during the DLT evaluation period to the highest dose level of DLT.
At the end of Cycle 1( first cycle is 21 days, subsequent cycles are 14 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
AUC(0-inf)after cycle 6 administration
Time Frame: 91 days after first dose of BAT8008
The area under the concentration-time curve extrapolated from time 0 to infinity
91 days after first dose of BAT8008

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Presence of ADA/nentralizing antibodies（NAbs）
Time Frame: 91 days after first dose of BAT8008
presence of anti-drug antibody/ nentralizing antibodies
