Aduro Biotech’s Personalized LADD Therapy Featured in an Oral Presentation at SITC’s New Cancer Immunotherapy Agents in Development Program


Posted on: 09 Nov 16

BERKELEY, Calif., Nov. 09, 2016 (GLOBE NEWSWIRE) -- Aduro Biotech, Inc. (Nasdaq:ADRO), a biopharmaceutical company with three distinct immunotherapy technologies, announced that Tom Dubensky Jr., Ph.D., chief scientific officer of Aduro, presented today about the company’s personalized LADD technology at the Society for Immunotherapy of Cancer (SITC) distinct session titled New Cancer Immunotherapy Agents in Development being held in conjunction with the SITC annual meeting.

LADD is Aduro's proprietary platform of live, attenuated double-deleted Listeria monocytogenes strains that have been engineered to express tumor-associated antigens to induce an innate immune response and tumor-specific T cell-mediated immunity.  Personalized LADD, or pLADD, is a second generation LADD technology that is being designed for individualized, patient-specific immunotherapy.  The pLADD approach leverages the immune activating activity of the Listeria bacterial vector in combination with neoantigens, or the tumor markers specific to an individual’s cancer, which are derived from the patient’s own unique tumor cells. Once administered, pLADD therapies are expected to mobilize the immune system through first an immediate recognition of the presence of Listeria as being foreign and then second a specific and customized immune attack on cells containing the tumor neoantigens presented by pLADD.  An Investigational New Drug (IND) application has been accepted, and a Phase 1 trial evaluating the safety and immunogenicity of pLADD in patients with advanced gastro-intestinal cancers is planned.

“There is tremendous excitement in the oncology field to develop personalized therapies as the next new wave in immunotherapy to specifically customize treatment for each patient based on neoantigens that are unique to a patient’s tumor,” said Tom Dubensky Jr., Ph.D., chief scientific officer of Aduro. “We are excited about the potential of our pLADD program, which has been shown to induce anti-tumor immune responses specific to tumor neoantigens and correlate with longer survival in preclinical models. Additionally, in these models, we observed a synergistic anti-tumor effect when pLADD was combined with an anti-PD-1 antibody, resulting in a significant reduction in tumor volume and increased survival.”

The pLADD technology platform is well-suited to maximize the potential benefit of personalized therapy through the ability to engineer the therapy with multiple tumor-specific neoantigens, as well as to leverage an efficient small-scale manufacturing process in its production.

To create a patient-specific pLADD therapy, a physician begins by removing tumor cells from the patient. These cells are analyzed in order to molecularly characterize (sequence) the tumor, including any mutations that are unique to the patient’s own tumor cells. Predictive algorithms for antigen processing are run to identify pertinent tumor antigens. Aduro then creates a LADD strain that includes the patient-specific neoantigens for administration.

Preclinical Data with pLADD
Preclinical data showed that pLADD induced a robust immune response, including broad innate immune responses involving cytokines, chemokines, natural killer, and gamma delta T cells, as well as antigen-specific adaptive T cell responses (CD8+ and CD4+).  In preclinical models, pLADD remodeled the tumor microenvironment, whereby an increase in infiltration of neutrophils, T cells and dendritic cells was observed. The combination of pLADD with an anti-PD-1 led to a sustained immune response and significant prolongation of survival in these models.

Detailed preclinical data will be presented by Aduro scientist Meredith Leong, Ph.D., on Saturday, November 12, 2016 at the SITC Annual Meeting (Poster #366).

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 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 www.aduro.com.
