AbbVie and CytomX Therapeutics, Inc. announced that they have entered into a collaboration to co-develop and co-commercialize Probody™ Drug Conjugates against CD71, also known as transferrin receptor 1 (TfR1). CD71 is highly expressed in a number of solid and hematologic cancers and has attractive molecular properties for efficient delivery of cytotoxic payloads to tumor cells. Probody therapeutics are designed to take advantage of unique conditions in the tumor microenvironment to enhance the tumor-targeting features of an antibody and reduce drug activity in healthy tissues.

In September 2015, then 44 year-old CEO of BioViva USA Inc. Elizabeth Parrish received two of her own company's experimental gene therapies: one to protect against loss of muscle mass with age, another to battle stem cell depletion responsible for diverse age-related diseases and infirmities.
