Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What data supports the effectiveness of the treatment iC9-CAR.B7-H3 T cells for ovarian cancer?

Research shows that CAR-T cells targeting B7-H3 can control the growth of ovarian cancer in lab and animal studies, suggesting they might be effective in treating this cancer. Additionally, B7-H3 is a promising target because it is highly expressed in ovarian cancer cells, which may help overcome resistance to other treatments.12345

Is CAR-T cell therapy targeting B7-H3 safe for humans?

Initial trials of CAR-T cell therapy targeting B7-H3 have shown it to be safe, with no evident toxicity in preclinical models. However, other CAR-T therapies, like those targeting B7-H4, have shown delayed toxic effects, highlighting the importance of ongoing safety evaluations.14567

What makes the iC9-CAR.B7-H3 T cell treatment unique for ovarian cancer?

The iC9-CAR.B7-H3 T cell treatment is unique because it targets the B7-H3 protein, which is highly expressed in ovarian cancer cells but not in normal tissues, making it a promising target for immunotherapy. This approach is particularly beneficial for patients who do not respond to traditional PD-1/PD-L1 therapies, as B7-H3 is a different checkpoint molecule involved in suppressing the immune response.13458

What is the purpose of this trial?

The purpose of this study is to test the safety and tolerability of using a new treatment called autologous T lymphocyte chimeric antigen receptor cells against the B7-H3 antigen (iC9-CAR.B7-H3 T cells) in patients with ovarian cancer that came back after receiving standard therapy for this cancer. The iC9.CAR.B7-H3 treatment is experimental and has not been approved by the Food and Drug Administration. The study team wants to know how much (dose) of the iC9-CAR.B7-H3 T cells are safe to use in patients without causing too many side effects and what is the maximum dose could be tolerated.There are two parts to this study. In part 1, approximately blood will be collected from subjects to prepare the iC9.CAR.B7-H3 T cells. The study team will collect disease-fighting T cells from the blood and modify them to prepare the iC9.CAR.B7-H3 T cells. In part 2, the iC9.CAR.B7-H3 T cells will be given to eligible subjects by infusion three days after completion of lymphodepletion chemotherapy.

Findings from Research

B7-H3.CAR-T cells effectively controlled the growth of various cancers, including pancreatic ductal adenocarcinoma, ovarian cancer, and neuroblastoma, in both laboratory and mouse models, indicating their potential as a powerful immunotherapy.
The use of 4-1BB co-stimulation in B7-H3.CAR-T cells led to lower PD-1 expression and enhanced antitumor activity, suggesting a mechanism that could improve the effectiveness of these CAR-T therapies without causing significant toxicity.
Antitumor Responses in the Absence of Toxicity in Solid Tumors by Targeting B7-H3 via Chimeric Antigen Receptor T Cells.Du, H., Hirabayashi, K., Ahn, S., et al.[2021]
A specific population of tissue-resident memory T cells (TIM-3/CXCL13-positive) was identified in epithelial ovarian cancer (EOC), which is associated with improved survival in patients, based on analysis of around 175 patients with high-grade serous EOC.
The study suggests that combining TIM-3 and PD-1 blockade therapies could enhance anti-cancer immunity in EOC, particularly since CXCL13-positive CD8 T cells are linked to better responses to existing immunotherapies.
Tumor infiltrating CD8/CD103/TIM-3-expressing lymphocytes in epithelial ovarian cancer co-express CXCL13 and associate with improved survival.Vlaming, M., Bilemjian, V., Freile, Jร., et al.[2022]
Adoptive T-cell therapies, particularly CAR T-cell therapy, are gaining attention for their potential to enhance immune responses against ovarian cancer, leveraging T cells' critical role in immune surveillance.
Recent advancements, such as dual specificity CARs and affinity-tuned single-chain Fv fragments, may improve the effectiveness and safety of CAR T-cell therapies compared to traditional T cell receptor therapies in clinical settings.
