A new approach against non-small-cell lung cancer (NSCLC) has combined immunotherapy with molecularly targeted therapy to activate the immune response and inhibit oncogenic pathways, which prevented tumor progression and eliminated cancer cells. Brigham and Women’s Hospital scientists have developed nanoparticles loaded with antibody conjugates that could deliver large amounts of treatment to the tumor tissue. This new strategy could improve the results of conventional immunotherapy in these patients and reduce toxicity of existing treatments.
