My lab develops antibody-based therapeutics for treating cancer. Our approach is to use antibodies or antibody fragments to deliver toxins for the purpose of killing cancer cells. Antibody-toxin molecules are called "immunotoxins". When immunotoxin treatment is less than 100% effective, we then add chemotherapy of various kinds to enhance killing. Along with our collaborators, discovering the best combinations of chemotherapy and immunotoxin has been the main goal of the lab for the past several years. Several particular combinations are under investigation for use in the clinic to treat patients with various malignancies.
