Executive Brief Modern oncology is constrained by a paradox: Clinical trials are the gold standard. Yet they are structurally incapable of testing most  biologically plausible treatment combinations. Metabolic therapies, repurposed drugs, dietary interventions, and immune-modulating strategies form a  combinatorial space too large, too unprofitable, and too complex  for conventional trial frameworks. This is where  AI-driven simulations  become essential.  AI-driven simulations  offer a way to prioritize biologically plausible combinations, generating hypotheses about how existing drugs and metabolic interventions might work together before any formal clinical trial begins. These models do not replace trials, but they help focus limited research resources on the most promising leads.  This report synthesizes: Cancer metabolism Immune energetics Repurposed drug mechanisms Immunothera...

Introduction: Immunotherapy Works — But Not Well Enough Immunotherapies like checkpoint inhibitors (PD-1, PD-L1, CTLA-4) and CAR-T cells have transformed cancer care. In select patients, they produce dramatic, durable responses that chemotherapy rarely achieves. Yet the uncomfortable truth remains: Most patients do not respond Many responses are partial or temporary Toxicity can be severe Resistance is common The emerging question in oncology is no longer whether immunotherapy works — but why it fails so often , and how those failures might be addressed. A growing body of research suggests the answer may lie not in better antibodies or engineered T-cells, but in tumor metabolism — and this is where repurposed drugs enter the picture. 1. The Metabolic Barrier to Immunotherapy Tumors do not merely evade the immune system genetically. They starve, poison, and exhaust immune cells metabolically . Key metabolic obstacles include: Glucose depletion Tumor cells consume glucose aggressive...

Introduction: CAR Therapy Has a Hidden Bottleneck CAR-T therapy is one of the most powerful cancer treatments ever developed. In certain blood cancers, it delivers remission rates chemotherapy never could. Yet outside a narrow set of indications, CAR-T struggles: Limited efficacy in solid tumors High toxicity (CRS, neurotoxicity) T-cell exhaustion Relapse after initial response CAR-NK therapy has emerged as a potential alternative—safer, more scalable, and possibly better suited for solid tumors. But there’s a deeper issue affecting both platforms: Engineered immune cells are being deployed into metabolically hostile environments they were never designed to survive. 1. CAR-T vs CAR-NK: A Brief Comparison CAR-T Cells Derived from patient (autologous) T-cells Highly potent cytotoxicity Strong memory formation High rates of cytokine release syndrome (CRS) Expensive and logistically complex CAR-NK Cells Derived from donor NK cells or cell lines Lower CRS risk “Off-the-shelf” scalability S...

Cancer treatment has transformed dramatically over the past decade. From chemotherapy and radiation to targeted therapies, each advance has sought to tip the balance in favor of the patient. Now, cell-based immunotherapies — therapies that harness and engineer the body’s immune system to fight cancer — are taking center stage. Two of the most promising approaches are CAR-T and CAR-NK cell therapies. But what makes them different, and how are emerging innovations, including AI and NK cell expansion, shaping the future of immunotherapy? Understanding CAR-T Therapy CAR-T (Chimeric Antigen Receptor T-cell) therapy involves harvesting a patient’s T cells, genetically engineering them to recognize specific cancer antigens, and reinfusing them into the body. These modified T cells can detect and destroy cancer cells with remarkable precision. Strengths of CAR-T: High efficacy in blood cancers: Durable remissions have been reported in leukemia and lymphoma patients. Long-term immune memory: ...

Breast cancer remains one of the most challenging and prevalent malignancies worldwide, with metastatic and treatment-resistant cases posing significant therapeutic hurdles. Conventional treatment options, including chemotherapy, targeted therapies, and immunotherapy, often reach their limits, particularly in advanced stages such as triple-negative breast cancer (TNBC).  For patients with actionable mutations identified through molecular profiling, targeted therapies are the preferred treatment approach. In particular, for estrogen receptor–positive (ER+) breast cancer patients with a low Oncotype DX recurrence score, hormonal therapy alone is often appropriate, as genomic testing indicates a low risk of cancer recurrence and supports de-escalation of more aggressive systemic treatments. The preference for targeted treatments reflects their demonstrated efficacy in improving outcomes in these molecularly defined subgroups, underscoring the importance of comprehensive genomic profil...
