What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new treatment using specialized immune cells called CAR T cells to target cancers displaying the protein CD70. The goal is to test the safety and potential effectiveness of this therapy for individuals whose cancer, such as lymphoma, myeloma, or certain solid tumors, has returned after standard treatments. Participants should have a CD70-positive tumor with at least 26% of the tumor cells showing this protein and have experienced a recurrence or lack of success with typical treatments.

As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this innovative therapy.

Will I have to stop taking my current medications?

The trial requires that you stop taking systemic chemotherapy at least 2 weeks before starting the study treatment. It also excludes those currently on high-dose steroids or certain other treatments. Please discuss your specific medications with the trial team to see if they are allowed.

Is there any evidence suggesting that this trial's treatment is likely to be safe?

Research shows that CD70-targeted CAR T cells are under study for safety and effectiveness in treating certain cancers. For patients with T-cell lymphoma, studies have found that a similar treatment, CTX130, can be administered safely. The side effects were manageable, indicating they were not severe and could be handled well, suggesting patients tolerated the treatment well.

For myeloma, early studies on CD70-targeted CAR T cells have shown promise regarding safety. The treatment was effective without causing major safety issues, meaning that while some side effects could occur, they were not serious enough to halt the treatment.

These findings provide some confidence that CD70-targeted CAR T cells may be safe for people with these cancers. However, this specific trial remains in its early phase, primarily aiming to test safety. While earlier studies offer hope, the main goal here is to carefully monitor for any side effects and ensure the treatment is safe for everyone involved.12345

Why are researchers excited about this study treatment?

CD70.CAR is unique because it uses a novel approach called CAR-T cell therapy to target cancer cells. Unlike traditional chemotherapy that attacks cancer broadly, CAR-T cell therapy involves modifying a patient's T cells to specifically seek out and destroy cancer cells expressing the CD70 protein. Researchers are excited about this treatment because it has the potential to provide a more precise, potent attack on tumors with fewer side effects compared to broad-spectrum treatments. Additionally, CD70.CAR's ability to target both lymphoma and solid tumors, as well as myeloma, could mean a wider range of applications for patients with different types of cancer.

What evidence suggests that this trial's treatments could be effective for cancer?

Research shows that CD70.CAR T cells could offer a promising new way to treat certain cancers. Earlier studies have found that treatments targeting CD70 are effective, particularly for blood cancers like lymphoma and myeloma, which often express the CD70 protein. In this trial, participants in Treatment Arm A will receive CD70.CAR T cells for lymphoma and solid tumors, while those in Treatment Arm B will receive the same treatment for myeloma. In myeloma, CD70 is associated with more severe cases and lower survival rates, so targeting it might help control the disease. While CAR T therapy has proven effective for blood cancers, its effects on solid tumors, such as some sarcomas and kidney cancers, remain under investigation, with early results appearing hopeful. These specially designed CAR T cells can grow and persist longer, enhancing their ability to fight cancer cells.16789
