N-803 for Soft Tissue Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effectiveness of a treatment called N-803 for individuals with certain types of soft tissue cancer, such as synovial sarcoma or myxoid/round cell liposarcoma. These rare cancers can return or worsen after initial therapy. N-803, a form of immunotherapy, helps the body's immune system combat cancer by activating immune cells. The trial seeks participants with these cancers who have previously received a specific type of cellular therapy but still experience growing or worsening cancer. Participants should be able to undergo a procedure to collect white blood cells and should have previously benefited from their initial therapy. As a Phase 1 trial, this research aims to understand how N-803 works in people, offering participants the chance to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are on certain anticancer treatments or medications that affect the heart rhythm, you may need to stop them before starting the trial. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that N-803 is likely to be safe for humans?
Research has shown that N-803, a type of immunotherapy, has generally been safe in earlier studies. In one study, N-803 combined with another treatment called BCG proved effective and well-tolerated by patients with a specific type of bladder cancer. This finding suggests that N-803 might also be safe for other cancers, such as synovial sarcoma or myxoid/round cell liposarcoma.
Another study found that N-803 caused only mild side effects, indicating that most people did not experience serious reactions. The treatment also exhibited low immunogenicity, meaning it did not trigger a strong immune response that could lead to complications.
Overall, early research suggests that N-803 is safe and tolerable. However, as this is an early phase study, further research is necessary to confirm these results for different types of cancer.12345Why do researchers think this study treatment might be promising?
Researchers are excited about N-803 for soft tissue cancer because it offers a novel approach to boosting the immune system. Unlike traditional chemotherapy and radiation, which directly target cancer cells, N-803 enhances the body's own immune response by stimulating natural killer (NK) cells. This unique mechanism of action could potentially lead to fewer side effects and a more targeted attack on cancer cells. Additionally, the subcutaneous delivery of N-803 allows for repeated dosages every two weeks, which may offer a more consistent therapeutic effect compared to standard treatments.
What evidence suggests that N-803 might be an effective treatment for soft tissue cancer?
Research has shown that N-803, which participants in this trial will receive, could be a promising treatment for soft tissue cancers like synovial sarcoma and myxoid/round cell liposarcoma. N-803 is a type of immunotherapy that uses a protein called interleukin-15 (IL-15) to strengthen the body's immune system to fight cancer cells. This treatment activates and increases immune cells, helping them attack cancer more effectively. Early studies suggest that N-803, when combined with other treatments, may benefit people with soft tissue sarcoma. While more research is needed, these initial findings offer encouragement for those considering N-803.678910

Treatment groups
Experimental Treatment
Patients receive N-803 SC on day 1 of each cycle. Cycles repeat every 14 days for up to 52 cycles in the absence of disease progression or unacceptable toxicity. Patients also undergo leukapheresis during screening up until day 1 cycle 1 and during treatment on day 8 cycle 4. Patients also undergo CT, chest x-ray, or MRI as well as blood sample collection throughout the trial.
