Advaxis Presents an Overview of its Lm Platform and Neoantigen-Directed Programs at the Immuno-Oncology 360° Conference

Advaxis, Inc. (NASDAQ:ADXS), (the Company) a late-stage biotechnology company focused on the discovery, development and commercialization of immunotherapy products, announces the presentation of the progression of its Lm platform from discovery to clinical application, and the unique opportunity the platform affords Advaxis in its pursuit of innovative new cancer therapeutics.

The presentation is being made today by Robert G. Petit, Ph.D., the Company’s Chief Scientific Officer and Executive Vice President and Andres A. Gutierrez, M.D., Ph.D., the Company’s Chief Medical Officer and Executive Vice President, during a plenary session at the Immuno-Oncology 360° Conference at the Crowne Plaza Times Square in New York City. The session begins at 4:00 p.m. ET and the Company’s presentation begins at 4:55 p.m. ET.

Drs. Petit and Gutierrez will provide an overview of the Company’s proprietary Lm platform, including the following features that have been observed:

• Ability to generate CD8+ T cells rapidly and against large percentage of peptides/neoantigens targets;
• Excellent priming without adding adjuvant, systemic pro-inflammatory immune “macroenvironment”;
• Antigen spreading demonstrated in clinical trials including our neoantigen-directed drug constructs;
• No neutralizing antibodies allowing for repeat boosting;
• Efficacy signals include single agent complete responses in late stage cancer and improved survival; and
• Manageable safety profile – nearly 500 patients treated to date, mostly grade 1 or grade 2 treatment related adverse events.

Drs. Petit and Gutierrez will also present an overview of the Company’s neoantigen-directed therapy programs, ADXS-NEO (customized, personalized neoantigens) and ADXS-HOT (off-the-shelf, hotspot or shared neoantigens and other antigens). The presentation will be available on the Company’s website, www.advaxis.com.

“We are looking forward to presenting an overview of our proprietary Lm platform which, over the last several years, has accumulated a large amount of data supporting immune response, clinical activity and safety in the treatment of multiple cancers. Leveraging the knowledge gained from our single-antigen targeting constructs, we have further optimized our Lm vector in the development of our multiple-antigen targeting constructs. Our discussion today will provide insight into immunological activity that we’ve observed in our ADXS-NEO clinical trial,” said Dr. Petit. He concluded, “These preliminary data suggest our approach may be among the best-in-class for CD8+ T cell response which we believe is important for successful clinical outcomes.”

“We have a broad pipeline of drug candidates being evaluated for multiple cancer types at various stages of development. We anticipate our first drug construct from our ADXS-HOT program, ADXS-503 for non-small cell lung cancer, to enter the clinic later this quarter.” said Dr. Gutierrez. He added, “We believe that our neoantigen-directed drug candidates will likely be used in combination with checkpoint inhibitors and have the potential to significantly impact the cancer treatment paradigm.” He concluded, “The preliminary clinical data from our ADXS-NEO Phase 1 study demonstrate broad and rapid anti-tumor immunity. We are looking forward to providing clinical data read-outs from several studies throughout 2019.”

ADXS-NEO, the Company’s personalized neoantigen program, is in an ongoing Phase 1 dose-escalation study to treat a variety of cancers. ADXS-HOT is the Company’s off-the-shelf program and consists of several different drug constructs that target hotspot or shared neoantigens, and other antigens. We expect the first drug construct from this program, ADXS-503, or HOT-Lung, will enter the clinic this quarter.

About Advaxis, Inc.

Advaxis, Inc. is a late-stage biotechnology company focused on the discovery, development and commercialization of proprietary Lm-based antigen delivery products. These immunotherapies are based on a platform technology that utilizes live attenuated Listeria monocytogenes (Lm) bioengineered to secrete antigen/adjuvant fusion proteins. These Lm-based strains are believed to be a significant advancement in immunotherapy as they integrate multiple functions into a single immunotherapy and are designed to access and direct antigen presenting cells to stimulate anti-tumor T cell immunity, activate the immune system with the equivalent of multiple adjuvants, and simultaneously reduce tumor protection in the tumor microenvironment to enable the T cells to eliminate tumors. Advaxis has four franchises in various stages of clinical and preclinical development: HPV-associated cancers, personalized neoantigen-directed immunotherapy, off-the-shelf, hotspot/cancer antigens neoantigen-directed immunotherapy and prostate cancer.
