SGLT-2 Inhibitors

\*\*Revised version:\*\* Locally advanced or advanced solid tumors remain a major clinical challenge despite multimodal treatments, including surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. For patients with unresectable, recurrent, metastatic, or treatment-refractory disease, prognosis remains poor, and effective therapeutic strategies are still urgently needed. Immune checkpoint inhibitors (ICIs), particularly PD-1/PD-L1 blockade, have transformed the treatment landscape of multiple solid tumors by reinvigorating anti-tumor immune responses through inhibition of the PD-1/PD-L1 pathway. However, only a subset of patients derive durable benefit from immunotherapy, and primary or acquired resistance remains common, highlighting the need for rational combination strategies to enhance anti-tumor efficacy. Intriguingly, sodium-glucose cotransporter 2 inhibitors, originally developed as anti-diabetic agents, have shown emerging anti-tumor potential through metabolic regulation and modulation of the tumor microenvironment. In particular, combining SGLT-2 inhibition with immune checkpoint blockade may enhance tumor control through metabolic-immunologic crosstalk. Preclinical evidence suggests that the SGLT-2 inhibitor canagliflozin may suppress tumor growth and potentially improve the efficacy of PD-1 blockade. Based on this rationale, this phase I trial investigates the safety and efficacy of canagliflozin combined with tislelizumab in patients with locally advanced or advanced solid tumors, evaluating its impact on progression-free survival, overall survival, objective response rate, and tumor microenvironment modulation. This study aims to explore a novel metabolic-immunotherapy strategy based on dual metabolic and immune regulation, potentially providing a new therapeutic option for patients with locally advanced or advanced solid tumors.

Empagliflozin is a drug given to lower glucose. It is used in the treatment of diabetes. However, it was shown to improve symptoms and survival of patients who are suffering from heart failure. The exact mechanism of this effect is currently not clearly understood. He hypothesize that empagliflozin has other properties than glucose lowering, that can explain its efficacy. One of these properties, is an anti-inflammatory effect. To document this, we are using a model of inflammation following percutaneous coronary scenting. We know that patients who get a stent will develop inflammation following stenting. This is documenting by a higher level of C-Reactive Protein 24 hours after the procedure. Patients who will participate in the study, will receive empagliflozin or a placebo tablet for 3 days prior to the revascularisation procedure. CRP and other inflammatory markers will be measured before intervention and 24 hours later. The goal is to demonstrate a lower rise in CRP following intervention in patients treated with empagliflozin vs. those who have received a placebo.
