简要总结
Some solid tumors make a lot of a protein called glypican 3(GPC3), which helps it to grow. Healthy cells and tissues do not make GPC3. TAK-102 is a medicine that sticks to GCP3 and stops it from working. It is hoped that TAK-102 will eventually treat people with solid tumors with the GPC3 protein. TAK-102 will be added to each person's white blood cells so is custom-made for each person.
In this study, people with solid tumors with GPC3 will receive TAK-102 with their white blood cells. The main aims of this study are to check if the participants get any side effects from treatment with TAK-102 and to check how much TAK-102 they can receive without getting side effects from it. Researchers can then work out the best dose of TAK-102 to give to participants in future studies.
At the first visit, the study doctor will check who can take part. For those who can take part, the study doctors will collect white blood cells from each participant. These cells are sent to the laboratory where TAK-102 is added to each participant's cells. This can take up to 4 weeks. Participants will receive specific treatments while they are waiting for TAK-102. Then, participants will receive TAK-102 with their cells slowly through a vein (infusion). 3 different small groups of participants will receive lower to higher doses of TAK-102. Each participant will just receive 1 dose. The study doctors will check for side effects after each different dose of TAK 102. In this way, researchers can work out the best dose of TAK-102 to give to participants in future studies.
Participants will stay in hospital for 28 days or longer for their treatment. Then, they will visit the clinic for regular check-ups for up to 36 months.
详细描述
The drug being tested in this study is called TAK-102. TAK-102 is being tested to treat people who have GPC3-expressing previously treated solid tumors. This study will look at the safety and tolerability of TAK-102 and will determine the RP2D of TAK-102.
The study will enroll approximately 14 participants, with a maximum of 18 participants. Participants will be assigned to 1 of the 3 treatment groups (dose cohorts) and dose escalation will be conducted in this study:
- Cohort 1: 1 × 10^7 CAR (+) cells/body [starting dose].
- Cohort 2: 1 × 10^8 CAR (+) cells/body.
- Cohort 3: 1 × 10^9 CAR (+) cells/body.
In case Cohort 1 is not tolerable, the dose level will be de-escalated to Cohort -1: 3 × 10^6 CAR (+) cells/body. Dose level(s) between planned cohorts and/or other dosing schedules may also be tested.
This study consists of the Screening, Pretreatment, and Treatment and Primary Follow-up phases. In Treatment and Primary Follow-up phases, all participants will be asked to receive a single intravenous infusion of TAK-102 and administration of TAK-102 will continue up to Month 12.

结局指标
主要结局
Number of Participants with First Cycle Dose-Limiting Toxicities (DLTs)
时间窗: Up to 28 days
Toxicity will be evaluated according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 5.0. DLT will be defined as any of the events specified in the protocol that are considered by the investigator to be at least possibly related to therapy with study medications.
Number of Participants With One or More Treatment-emergent Adverse Event (TEAE)
时间窗: Up to 3 year
An adverse event (AE) means any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to the medicinal product. This includes any newly occurring event, or a previous condition that has increased in severity or frequency since the administration of study drug.
Number of Participants With Adverse Events of Clinical Interest
时间窗: Up to 3 year
Adverse events of clinical interest include severe immune effector cell-associated neurotoxicity syndrome (ICANS), cytokine release syndrome (CRS), hemophagocytic lymphohistiocytosis (HLH), macrophage activation syndrome (MAS), tumor lysis syndrome (TLS), and liver function abnormality.
