CAR T-cell therapy is growing fast, with new targets bringing hope to cancer patients. Researchers are looking at new antigens on cancer cells to make treatments better and reduce relapse.
CD19-targeted CAR T-cell therapies have been successful. Now, we’re looking at other targets to treat more cancers. Next-generation CAR T therapies aim to target different antigens, improving treatment options.
Finding the right target antigen is key in CAR T-cell therapy. Antigen selection affects how well and safely CAR T-cell products work. By exploring new targets, we can help patients who haven’t responded to current treatments.
CD22 is a promising target for CAR T-cell therapy, mainly for patients who’ve had CD19 treatments. CD22-targeted CAR T cells have shown good results in trials. We’re studying how to use these treatments in practice.
Developing CD22-targeted CAR T-cell therapies is a big step forward. It gives patients another option, helping to overcome resistance to CD19 treatments and improve outcomes.
B-cell maturation antigen (BCMA) is a key target for CAR T-cell therapy in multiple myeloma. BCMA-directed CAR T cells have shown high response rates in trials. We’re looking into how to make these therapies even better.
The success of BCMA-directed CAR T-cell therapies is changing how we treat multiple myeloma. We’re working to make these treatments safer and more effective for patients.
As CAR T-cell therapy grows, knowing who can get it and who will respond is key. It’s a complex treatment that needs careful patient checks. This ensures it works well and is safe.
Only about 3.4% of patients can get CAR T-cell therapy. This is because of strict rules about who can get it. It shows we must pick patients carefully for the best results.
Healthcare teams look at many things. They check the cancer type, how far it’s spread, and the patient’s health. This helps find who will likely do well with CAR T-cell therapy.
Rules about who can get CAR T-cell therapy are important. They look at things like specific markers, how far the disease has spread, and if the patient can handle side effects.
| Inclusion Criteria | Exclusion Criteria |
|---|---|
| Presence of CD19+ cells in B-cell malignancies | Active CNS involvement or CNS disease |
| Refractory or relapsed disease after standard treatments | Severe comorbidities or poor performance status |
| Adequate organ function to tolerate CAR T-cell therapy | Previous CAR T-cell therapy or other gene therapies |
Biomarkers are vital for knowing if CAR T-cell therapy will work. They help doctors pick the right patients for the treatment.
Key biomarkers being studied include:
Using these biomarkers in patient selection can make CAR T-cell therapy more effective. This leads to better results for patients.
CAR T-cell therapy is growing, but it faces big challenges. These include severe side effects and making the therapy. We will look at the main issues in CAR T-cell therapy trials. This includes managing serious side effects, dealing with relapse, and the complex manufacturing process.
CAR T-cell therapy can cause serious side effects like neurotoxicity and CRS. These can be very dangerous and need careful watching. Studies show that up to 90% of patients might get CRS https://www.nature.com/articles/s41392-025-02269-w. Finding good ways to manage these side effects is key.
To tackle these issues, researchers are looking at different methods. This includes using corticosteroids and anti-IL-6 receptor antibodies. They are also studying biomarkers to predict who might get worse side effects.
