India's new 'smart' cancer drug could transform cancer treatment

Indian scientists have developed RK-251, a promising “smart” cancer drug designed to activate mainly inside cancer cells while limiting damage to healthy tissue. Developed by researchers from IASST and IIT-Guwahati, the drug showed strong activity against aggressive triple-negative breast cancer cells in preclinical studies. The breakthrough could offer a more targeted alternative to conventional chemotherapy, but human clinical trials are still needed before its safety and effectiveness can be established.
