Slide 10: Intensity's solution
13 Intensity’s solution • Tumor saturated with cytotoxics dies • Large quantities of antigen are released to immune cells • Tumor now favorable to T‐cell influx Issues with current systemic therapies • Lack of blood vessels • Drugs are unable to reach most of the tumor • Tumors can exclude T‐cells •
Slide 11: INT230-6 Dosing Paradigm is Personalized
15 Current Systemic Treatment Approach Dosing is set by patient’s height and weight, or fixed dosing, though body size has no correlation with survival Our Treatment Approach INT230-6 dosing is set by amount of patient’s tumor burden, dose for each tumor is set by its size Those patients with more d
