    On October 15, Advaxis provided an interim clinical update on the BrUOG investigator-sponsored Phase 1/2 trial of ADXS-HPV in anal cancer. At present, 7 of 8 patients out of the planned total accrual of 25 patients had completed the treatment regimen and had no evidence of disease and [insert statement regarding safety findings from preliminary data].

ADXS-PSA

  • Advaxis & Merck & Co., Inc. (Merck) Enter Into Immunotherapy + Checkpoint Inhibitor Clinical Trial Collaboration Agreement Targeting mCRPC; Received IND Clearance to Commence Phase 1/2 Study
    On August 25, Advaxis entered into a clinical trial collaboration with Merck to evaluate the combination of Advaxis's Lm-LLO cancer immunotherapy, ADXS-PSA (ADXS31-142), with Merck's investigational anti PD-1 antibody, KEYTRUDA® (pembrolizumab). The collaboration with Merck marked Advaxis's second high-profile checkpoint inhibitor combination agreement involving its Lm-LLO immunotherapy, following its previously announced agreement with MedImmune. On December 8, Advaxis announced that the FDA cleared its IND application to conduct a Phase 1/2 clinical study of ADXS-PSA in combination with KEYTRUDA in patients with previously treated, mCRPC. The clinical trial, which will be the first-in-human study of Advaxis's lead Lm-LLO immunotherapy product candidate in prostate cancer, is expected to begin patient enrollment in the first quarter of 2015.

ADXS-HER2

  • Advaxis's ADXS-cHER2 Immunotherapy Demonstrated T-Cell Immune Response in Preliminary Canine Osteosarcoma Data; Suggests Delay or Prevention of the Development of Metastatic Disease by Targeting Micrometastases
    On October 30, Advaxis provided an interim data analysis of its ongoing Phase 1 clinical study of ADXS-HER2 in canine osteosarcoma indicating that the early data suggest the immunotherapy breaks peripheral tolerance to HER2/Neu and induces HER2-specific T cell responses in dogs. Additionally, the data suggests that immune responses induced by ADXS-HER2 targets micrometastases and prevents the development of metastatic disease in this spontaneous and clinically relevant model of human osteosarcoma. The data analysis was performed as an extension of the Phase 1 canine osteosarcoma clinical trial being conducted at the University of Pennsylvania School of Veterinary Medicine. According to the data analysis, 50% of the dogs treated with ADXS-HER2 generated immunological responses against HER2 within four months of treatment.

About Advaxis, Inc.

Advaxis is a clinical-stage biotechnology company developing multiple cancer immunotherapies based on its proprietary Lm-LLO platform technology. The Lm-LLO technology, using bioengineered live attenuated Listeria monocytogenes bacteria, is the only known cancer immunotherapy agent shown in preclinical studies to both generate cancer fighting T-cells directed against a cancer antigen and neutralize Tregs and myeloid-derived suppressor cells (MDSCs), that protect the tumor microenvironment from immunologic attack and contribute to tumor growth. Advaxis's lead Lm-LLO immunotherapy, ADXS-HPV, targets human papillomavirus (HPV)-associated cancers and is in clinical trials for three indications: Phase 2 in invasive cervical cancer, Phase 1/2 in head and neck cancer, and Phase 1/2 in anal cancer. The FDA has granted Advaxis orphan drug designation for each of these three indications. The Company plans to initiate a registrational clinical program for cervical cancer in 2015 and has established licensing partners in India and Asia for commercialization in those regions. Advaxis entered into a clinical trial collaboration with MedImmune, the global biologics research and development arm of AstraZeneca, for a Phase 1/2 immunotherapy study to evaluate the safety and efficacy of MedImmune's investigational anti-PD-L1 immune checkpoint inhibitor, MEDI4736, in combination with Advaxis's ADXS-HPV as a treatment for patients with advanced, recurrent or refractory HPV-associated cervical cancer and HPV-associated head and neck cancer.

Advaxis's second Lm-LLO immunotherapy candidate in clinical testing will be ADXS-PSA, which is being developed to address prostate cancer. Advaxis entered into a clinical trial collaboration agreement with Merck & Co., Inc. ("Merck"), known as MSD outside the United States and Canada, through its subsidiaries, to evaluate the combination of Advaxis's Lm-LLO cancer immunotherapy, ADXS-PSA, with Merck's PD-1 checkpoint inhibitor KEYTRUDA® (pembrolizumab). The planned clinical trial will evaluate the safety and efficacy of ADXS-PSA as monotherapy and in combination with pembrolizumab in a Phase 1/2 study of patients with previously treated metastatic, castration-resistant prostate cancer.

Advaxis is also developing Lm-LLO immunotherapy ADXS-HER2, to target the Her2 receptor expressing cancers. Her2 is expressed in certain solid-tumor cancers, including pediatric bone cancer (or osteosarcoma), breast cancer, esophageal, and gastric cancer. ADXS-cHER2 has received orphan drug designation by the U.S. Food and Drug Administration (FDA) for the treatment of osteosarcoma. Advaxis is developing ADXS-HER2 for both human and animal-health, and has seen encouraging data in canine osteosarcoma, which is considered a model for human osteosarcoma. Advaxis has licensed ADXS-HER2 and three other immunotherapy constructs to Aratana Therapeutics, Inc. for pet therapeutics.
