Company’s Ongoing Clinical Trials with LADD-based Therapies Include Mesothelioma and Ovarian Cancers as well as Personalized LADD (pLADD)

BERKELEY, CA, USA I November 21, 2016 I Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, today announced that the U.S. Food and Drug Administration (FDA) has lifted the partial clinical hold placed on its clinical trials evaluating the LADD (live, attenuated double-deleted) immunotherapy platform, enabling patient enrollment to resume in all Aduro-sponsored clinical studies.

“We are pleased to come to a rapid agreement with the FDA to resume new patient enrollment in our LADD clinical studies,” said Stephen T. Isaacs, chairman, president and CEO of Aduro Biotech. “With slight protocol modifications implemented, we remain on track to initiate a Phase 2 clinical study using our LADD-based therapy CRS-207 in combination with an anti-PD-1 compound for patients with mesothelioma in the first half of 2017. Additionally, we continue to make significant progress with our STING Pathway Activator and B-select Antibody programs and with our three diverse immunotherapy platforms, we believe we are uniquely positioned to bring innovative therapies to patients with late-stage cancers.”

In agreement with the FDA, Aduro’s LADD-based clinical trial protocols have been modified to include extended patient surveillance, to exclude patients with certain prosthetic devices that are not easily removed, and to add guidance to administer prophylactic antibiotics following LADD-based treatment for patients who may receive immune-suppressive treatments.

About Aduro
Aduro Biotech, Inc. is an immunotherapy company focused on the discovery, development and commercialization of therapies that transform the treatment of challenging diseases. Aduro’s three technology platforms, which are designed to harness the body’s natural immune system, are being investigated in cancer indications and have the potential to expand into autoimmune and infectious diseases. Aduro’s LADD technology platform is based on proprietary attenuated strains of Listeria that have been engineered to express tumor-associated antigens to induce specific and targeted immune responses. This platform is being developed as a treatment for multiple indications, including pancreatic, ovarian, lung and prostate cancers, mesothelioma and glioblastoma. Additionally, a personalized form of LADD, or pLADD, is being developed utilizing tumor neoantigens that are specific to an individual patient’s tumor. Aduro’s STING Pathway Activator platform is designed to activate the intracellular STING receptor, resulting in a potent tumor-specific immune response. ADU-S100 is the first STING Pathway Activator compound to enter the clinic and is currently being evaluated in a Phase 1 study in patients with cutaneously accessible metastatic solid tumors or lymphomas. Aduro’s B-select monoclonal antibody platform includes a number of immune modulating assets in research and preclinical development. Aduro is collaborating with leading global pharmaceutical companies to expand its products and technology platforms. For more information, please visit
