Advaxis Announces Receipt of Second Milestone Payment Under ADXS-HER2 Licensing Agreement with OS Therapies

PRINCETON, N.J., April 26, 2021 (GLOBE NEWSWIRE) -- Advaxis, Inc. (NASDAQ: ADXS), a clinical-stage biotechnology company focused on the development and commercialization of immunotherapy products, today announced that the Company has received the second milestone payment related to its licensing agreement for ADXS31-164, also known as ADXS-HER2, to OS Therapies for evaluation in the treatment of osteosarcoma in humans.

Under the terms of the license agreement, OS Therapies, in collaboration with the Children’s Oncology Group (COG), is responsible for the conduct and funding of a clinical study evaluating ADXS-HER2 in recurrent, completely resected osteosarcoma. OS Therapies recently completed a financing, triggering the second milestone payment. Under the agreement, Advaxis has the opportunity to receive additional clinical, regulatory, and sales-based milestone payments as well as royalties on future product sales. Additional details of the financial terms have not been disclosed.

“This funding milestone for OS Therapies brings OST-HER2, originally ADXS-HER2, one step closer to the clinic,” said Kenneth A. Berlin, President and Chief Executive Officer of Advaxis. “We are confident in the potential of OST-HER2, which had been approved in the U.S. for the adjuvant treatment of osteosarcoma in canines, and are proud to have played a role in the development of this important new candidate for osteosarcoma patients. We look forward to the team at OST advancing the program, building upon our early Phase 1 data evaluating ADXS-HER2.”

Mr. Berlin continued, “This milestone payment provides Advaxis additional capital as we build momentum across our growing ADXS-HOT neoantigen-directed off-the-shelf clinical programs. To date, we have assembled a robust clinical and translational data set which suggests our unique approach has the potential to enhance and/or restore responses to checkpoint inhibitors in lung cancer. We look forward to leveraging these resources as we advance ADXS-503, currently being evaluated in our Phase 1/2 study in NSCLC, and ADXS-504 for early-stage prostate cancer, which is on-track to enter the clinic in Q2 2021.”

About Advaxis, Inc.

Advaxis, Inc. is a clinical-stage biotechnology company focused on the development and commercialization of proprietary Lm-based antigen delivery products.

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 T cells to eliminate tumors.
