The engineered CD40 agonist antibody 2141-V11, engineered for enhanced efficacy and reduced side effects, has shown remarkable results. In a Phase 1 trial with metastatic melanoma, renal cell carcinoma, and breast cancer patients, nearly half experienced tumor shrinkage, including two complete remissions. This therapy involves the drug injection into tumors, which minimizes toxicity and triggers systemic immune responses, leading to tumor regressions even at uninjected sites. The treatment also promotes immune cell infiltration and tertiary lymphoid structure formation within tumors, associated with better outcomes.
CAR T-cell therapy and TIL therapies in solid tumors
[chimeric antigen receptor (CAR) T-cell therapy] has emerged as a groundbreaking treatment, especially for blood cancers. Beyond hematologic malignancies, its adaptation to solid tumors is gaining momentum. TIL therapies, which expand a patient’s own tumor-specific T cells, have shown tumor shrinkage in about 25% of refractory non-small cell lung cancer patients. These therapies genetically modify or expand immune cells to increase their specificity and potency against cancer.
Personalized cellular immunotherapy advances
Personalized immunotherapy for solid tumors has progressed with techniques involving genetic sequencing of tumor-specific T-cell receptors. These receptors are inserted into normal lymphocytes, creating a powerful tailored immune response. Early-phase trials demonstrated lasting tumor shrinkage in metastatic colorectal cancer patients using this approach combined with agents like pembrolizumab and IL-2. The method addresses the challenge of expanding specific anti-cancer T cells and enhancing their activity.
Challenges of tumor microenvironment and new solutions
A significant hurdle is the tumor microenvironment and NK cells, which suppresses immune cell functions. For instance, natural killer cells rapidly lose their cancer-killing ability within tumors. Research identifies strategies like Interleukin 15 role in immunotherapy to restore this function, enhancing immunotherapy effectiveness. Moreover, novel compounds targeting intracellular proteins, such as NR4A1 protein role in tumor growth, act like immune checkpoint inhibitors but access internal pathways, offering hope for patients resistant to current treatments. Combining these approaches with immune checkpoint inhibitors CTLA-4 and PD-1/PD-L1 and advanced delivery systems improves response rates and patient outcomes.
Clinical Trials Paving the Way for Immunotherapy-Only Cancer Treatment
How are MSK trials pioneering immunotherapy-only treatments for MMRd cancers?
Memorial Sloan Kettering Cancer Center (MSK) has led revolutionary Immunotherapy clinical trials focusing on mismatch repair-deficient (MMRd) cancers. These trials have demonstrated that immunotherapy alone can effectively treat cancers traditionally managed with surgery, chemotherapy, and radiation. In one trial involving 103 patients with various MMRd cancers—including rectal, colon, gastroesophageal, hepatobiliary, genitourinary, and gynecologic cancers—80% of participants avoided conventional treatments by relying exclusively on immunotherapy. Impressively, all rectal cancer patients achieved complete clinical response with tumor disappearance after the immunotherapy regimen.
In what ways are checkpoint inhibitors replacing surgery and chemotherapy?
The MSK trials utilized immune checkpoint inhibitors, particularly the PD-1 blocker dostarlimab (Jemperli), which unleashes the immune system to recognize and attack tumor cells more efficiently. By blocking these immune checkpoints, the therapy stimulates a robust anticancer immune response, rendering surgery and chemotherapy unnecessary for many patients who respond to the treatment. This approach improves outcomes by preserving organ function and significantly reducing the adverse effects related to traditional cancer therapies. Learn more about this immunotherapy breakthrough.

Additionally, radiotherapy combined with agents like vismodegib can extend control in basal cell carcinoma, highlighting multi-modal synergy.
What Are Emerging Strategies for Treating 'Cold' Tumors?
Some tumors lack significant immune cell infiltration, termed 'cold tumors,' making them resistant to immunotherapy alone. UCSF researchers found that targeting TGF-Beta signaling, a pathway associated with immune suppression, combined with radiation and checkpoint inhibitors, reprogrammed these tumors to become responsive. The development of the "beta-alt" tumor scoring system helps identify patients who may benefit from such combination strategies.
How Are Clinical Trials Incorporating Biomarkers to Optimize Therapies?
Innovations in clinical trials now emphasize responsive biomarkers like circulating tumor DNA (ctDNA) and tumor mutation burden to tailor immunotherapy. Trials using ctDNA testing have enabled real-time monitoring of treatment response, improving personalization. Biomarkers predicting immune checkpoint inhibitor efficacy, including mutations in CEBPA and IRS2 genes, are also shaping therapeutic decisions. For the latest in clinical trial results and biomarkers, see Cancer Immunotherapy News October 2025.
