NKG2D.Zeta-NK + CAR-T Cells for Bone Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new approach to combat advanced bone cancers like neuroblastoma and osteosarcoma that express GD2. It combines two types of genetically modified immune cells, NK cells and T cells, to better target and attack cancer cells. Specifically, the trial uses i15.NKG2D.zeta-NK cells and C7R.GD2.CAR-T cells. The goal is to determine the highest safe dose and assess how long these cells remain active in the body. Patients eligible for this trial have cancer that has returned or not responded to other treatments, and they can identify if their condition involves neuroblastoma or osteosarcoma that did not improve with standard care. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering patients the opportunity to be among the first to receive this innovative therapy.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop all current medications, but you cannot participate if you are currently taking immunosuppressive drugs, except for low-dose corticosteroids.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that C7R.GD2.CAR-T cells have been safe in past studies. These studies found that patients generally tolerated this treatment well, with no serious side effects limiting the dose. Some patients experienced mild side effects, such as temporary nerve issues, but these were not severe.
For i15.NKG2D.zeta-NK cells, less specific safety data is available on their own. However, NK cells are generally considered safe in many cancer treatments. Combining these cells with C7R.GD2.CAR-T cells aims to enhance treatment effectiveness and safety by helping the cells persist longer in the body.
As this is an early-phase trial, it focuses on identifying the safest dose levels. While some safety information is available, the trial continues to confirm how well these treatments are tolerated when used together.12345Why are researchers excited about this trial's treatments?
Unlike standard treatments for bone cancer, which often involve chemotherapy and radiation, the combination of i15.NKG2D.zeta NK cells and C7R.GD2.CAR-T cells introduces a novel approach. These treatments harness the power of the immune system, with CAR-T cells engineered to specifically target and destroy cancer cells. Moreover, the NKG2D.zeta NK cells are designed to enhance the immune response, potentially boosting the effectiveness of the CAR-T cells. Researchers are excited because this dual-action strategy could offer a more precise attack on cancer cells, leading to fewer side effects and possibly better outcomes for patients.
What evidence suggests that this trial's treatments could be effective for bone cancer?
Research has shown that a type of immune cell called IL-15-induced NK cells can effectively attack and destroy osteosarcoma cells, even those resistant to chemotherapy. These NK cells are specially modified to live longer and function better in the body. Studies have found that adding certain genes to these cells helps them persist and fight cancer more effectively.
In this trial, participants will receive a combination of i15.NKG2D.zeta NK cells and C7R.GD2.CAR-T cells. The GD2-targeted CAR-T cells have shown promise in treating neuroblastoma and osteosarcoma by recognizing GD2, a marker found on many cancer cells, and attacking them. By combining these NK and CAR-T cells, the treatment aims to leverage the strengths of both cell types, potentially offering a stronger defense against these hard-to-treat cancers.13567Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for patients with neuroblastoma or osteosarcoma that has returned after treatment or didn't respond to standard therapies. The cancer must have a substance called GD2 on its cells. There's no current standard treatment for these advanced cancers, and participants should not have received certain prior treatments.Inclusion Criteria

Trial Overview
The study tests the largest safe dose of i15.NKG2D.zeta-NK cells combined with C7R.GD2.CAR-T cells in patients, how long they stay in the blood, and their effect on cancer. These genetically modified immune cells are designed to recognize and fight cancer more effectively.

Experimental Treatment
Three dose levels will be evaluated. This is a dose escalating trial which will infuse doses of i15.NKG2D.zeta NK cells followed by a fixed dose of C7R.GD2.CAR T cells 5 days later.
