What is the purpose of this trial?

This trial explores a new treatment, NT-175, for individuals with advanced solid tumors that cannot be surgically removed or have spread (Stage III or IV) and have a specific gene mutation. The goal is to determine if this engineered T-Cell therapy can effectively target and combat these cancers. The trial will test different doses to identify the most effective one. Suitable candidates have solid tumors with a TP53 R175H mutation and have not found success with existing treatments. As a Phase 1 trial, this research aims to understand how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Will I have to stop taking my current medications?

The trial requires that you stop any systemic therapy at least 2 weeks or 3 half-lives (whichever is shorter) before enrolling. This means you may need to stop certain medications before participating.

Is there any evidence suggesting that NT-175 is likely to be safe for humans?

Research has shown that treatments like NT-175, which use T-cell receptors (TCR), have potential in fighting various types of cancer. In a study with a similar TCR-T cell treatment, some patients experienced benefits such as tumor reduction and disease stabilization. Importantly, this treatment was generally safe, with serious side effects being rare. Another study found that the risk of harmful genetic changes was very low (less than 0.1%) when NT-175 was tested in the lab.

Since NT-175 is new and still under investigation, researchers are closely monitoring its safety in humans. Early trials like this one aim to identify any risks and determine safe dosage levels. For those considering joining this trial, it's important to understand that the primary goal is to ensure the treatment's safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Researchers are excited about NT-175 because it represents a cutting-edge approach in the fight against cancer through engineered T-cell therapy. Unlike traditional treatments, such as chemotherapy or radiation, which can affect healthy cells, NT-175 specifically targets cancer cells using TCR T cells that are engineered to recognize and attack tumor cells. This precision targeting could potentially lead to more effective treatment outcomes with fewer side effects. Moreover, NT-175 is designed to adapt and expand within the patient's body, potentially offering a longer-lasting response compared to standard therapies.

What evidence suggests that NT-175 might be an effective treatment for cancer?

Research has shown that specially designed T cells, like those in NT-175, hold promise in fighting cancer. These T cells can locate and destroy cancer cells, particularly in blood cancers, and may also aid in treating common solid tumors. One study found that similar treatments reduced cancer in 81% of patients and completely eliminated it in 52% of cases. This trial will investigate NT-175's effectiveness, especially for solid tumors with the TP53 R175H mutation, through various treatment arms, including dose escalation and disease cohort expansion. Although these early results are encouraging, further research is needed to determine NT-175's efficacy for these specific conditions. ^{6 7 8 9 10}

Engineered T cell therapies, like CAR T cells and TCR T cell therapies, have shown remarkable efficacy in treating certain blood cancers, highlighting their potential as a powerful tool in cancer immunotherapy.

However, these therapies also pose unique safety challenges, such as cytokine release syndrome and neurotoxicity, which require careful nonclinical safety assessments to ensure patient safety during development.
