A Clinical Trial of TAA06 Injection in Advanced Solid Tumors

Study Purpose

B7-H3 (also known as CD276) is widely expressed on the surface of a variety of malignancies solid tumors, while it rarely or even doesn't express on normal tissues. Therefore, B7-H3 is an ideal target for chimeric antigen receptor (CAR) T cells therapy. TAA06 injection is a CAR T injection targeting B7-H3. This is a phase I clinical study with the primary objective of evaluating the safety and tolerability of TAA06 injection in subjects with TAA06-positive advanced solid tumors. The secondary objectives are as follows: to evaluate the distribution, proliferation and persistence of B7-H3-targeted CAR T cells after injection of TAA06 in subjects; to preliminarily evaluate the efficacy of TAA06 injection in subjects with TAA06-positive advanced solid tumor.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
