After iPRIME’s checkpoint-plus-chemo strategy missed its primary chemotherapy response endpoint, another oncology-focused development highlights practical support tools. A micro-costing analysis of an mHealth app pilot in Karnataka estimates the cost of building and piloting the cancer care app at ₹1,00,372 (about US$1,205), equal to 0.093% of the state’s program budget. The app was designed to help patients schedule chemotherapy, track treatment records, and coordinate care. The analysis breaks down costs across development, stakeholder engagement, and training in both urban and rural settings. For healthcare systems facing access and coordination constraints, the study provides an unusually granular budget benchmark for scaling digital oncology support in resource-limited environments.
