Trial Summary

Do I need to stop taking my current medications for the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are using systemic corticosteroids at doses ≥10 mg prednisone daily or its equivalent, you may not be eligible. Please discuss your current medications with the trial investigator for more details.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are using systemic corticosteroids at doses of 10 mg prednisone daily or more, you may not be eligible to participate.

What data supports the idea that CAR T-Cell Therapy for Ovarian Cancer is an effective treatment?

The available research shows that CAR T-Cell Therapy targeting B7-H3 can effectively control the growth of ovarian cancer in laboratory and animal studies. Specifically, the therapy was able to manage tumor growth in models that mimic human ovarian cancer without causing significant side effects. This suggests that CAR T-Cell Therapy could be a promising treatment option for ovarian cancer, potentially offering better outcomes compared to traditional methods like surgery and chemotherapy. However, it's important to note that while these findings are promising, further studies and clinical trials are needed to confirm its effectiveness and safety in humans.12345

What data supports the effectiveness of this treatment 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 potential effectiveness. B7-H3 is often overexpressed in ovarian tumors, and targeting it with CAR T-cells has shown promising results in reducing tumor growth.12345

What safety data exists for CAR T-Cell Therapy in ovarian cancer?

CAR T-Cell Therapy for ovarian cancer, particularly targeting B7-H3, has shown promise in preclinical and early clinical trials. B7-H3-targeted CAR-T cells have demonstrated antitumor activity with minimal toxicity in some models, but there are concerns about potential 'on-target, off-tumor' toxicities. B7-H4 CAR T-cell therapy showed delayed, lethal toxicity due to expression in normal tissues. Overall, while initial trials suggest safety, long-term effects and specific toxicities need further evaluation.13467

Is CAR T-Cell Therapy for Ovarian Cancer safe?

CAR T-Cell Therapy targeting B7-H3 has shown promise in controlling tumor growth without evident toxicity in some preclinical models, but other studies have reported delayed, lethal toxicity due to off-tumor effects. Initial trials suggest B7-H3-targeted CAR-T therapies are generally safe, though their effectiveness may be limited.13467

Is the treatment CAR.B7-H3 a promising treatment for ovarian cancer?

Yes, CAR.B7-H3 is a promising treatment for ovarian cancer. It targets a specific protein, B7-H3, which is found in high amounts on cancer cells but not much on normal cells. This makes it a good target for treatment. Studies have shown that CAR.B7-H3 can effectively control tumor growth in ovarian cancer and other cancers, making it a strong candidate for future treatments.13489

What makes CAR.B7-H3 treatment unique for ovarian cancer?

CAR.B7-H3 treatment is unique because it uses specially engineered T-cells to target the B7-H3 protein, which is highly expressed in ovarian cancer cells but not in normal tissues, potentially reducing side effects. This approach is different from traditional treatments like chemotherapy and surgery, as it harnesses the body's immune system to fight cancer.13489

What is the purpose of this trial?

This is single center, open-label phase 1 dose escalation trial that uses modified 3+3 design to identify a recommended phase 2 dose (RP2D) of CAR.B7-H3 T cell product. An expansion cohort will enroll additional subjects at the RP2D for a total enrollment of up to 21 subjects on the protocol.

Eligibility Criteria

This trial is for adults over 18 with recurrent ovarian cancer that's resistant to platinum-based chemotherapy and PARP inhibitors if they have BRCA mutations. Participants must be in good enough health to undergo procedures, agree to use two forms of contraception, and not be pregnant or breastfeeding. They can't join if they have certain other cancers, brain metastases, active infections like HIV or hepatitis, or recent bowel complications.

Inclusion Criteria

I am older than 18 years.
I am willing to have multiple biopsies as my doctor thinks it's safe.
Written informed consent to undergo cell procurement is explained to, understood by, and signed by the subject; the subject is given a copy of the informed consent form for cell procurement

Treatment Details

Interventions

  • CAR.B7-H3
  • Cyclophosphamide
  • Fludarabine
Trial Overview The study tests CAR T-cells targeting B7-H3 antigen in patients with ovarian cancer using a '3+3 design' to find the safest dose for phase 2 trials. Up to 21 people will receive this treatment after being screened for eligibility. The process includes placing an intraperitoneal port and multiple biopsies before and after treatment.

Experimental Treatment
Group I: CAR.B7-H3 T cell productExperimental Treatment3 Interventions
Up to 12 patients will receive three weekly CAR.B7-H3 T cell product infusions at the same dose. To determine the recommended phase 2 dose (RP2D), a modified 3+3 dose escalation design will be used to evaluate two dose levels: Dose Level 1 (7.5x10\^7 cells/infusion), Dose Level 2 (2x10\^8 cells/infusion). If this dose is not tolerated, then a lower dose of 3.75 × 10\^6 cells/infusion will be explored. Up to 3 dose levels of CAR.B7-H3 cells will be tested with at least 3 patients enrolled at each dose cohort before dose escalation is considered based on the incidence of dose limiting toxicity (DLT). An expansion cohort will enroll up to 9 patients at the recommended phase 2 dose. Prior to receiving the infusions, patients will undergo lymphodepletion with fludarabine and cyclophosphamide.

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]
B7-H4 and B7-H3 are overexpressed in ovarian tumors, with B7-H4 serving as a potential biomarker for ovarian cancer, especially when combined with CA125 levels.
Research indicates that blocking B7-H3 could reduce tumor growth and improve survival rates, suggesting it may be a promising therapeutic target, although further studies using antibody-mediated suppression are needed for clinical application.
A review of B7-H3 and B7-H4 immune molecules and their role in ovarian cancer.Fauci, JM., Straughn, JM., Ferrone, S., 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.
