Advaxis, Inc. a leader in
developing the next generation of immunotherapies for cancer and
infectious diseases, announced the publication of preclinical
research with ADXS-HPV, Advaxis’ Lm-LLO lead drug candidate, for
the treatment of HPV-associated cancers in combination with PD-1
antibody.
The studies demonstrated that treatment with an Lm-LLO immunotherapy, in combination with an anti-PD-1 antibody, significantly improved immune and therapeutic efficacy in preclinical mouse models. In addition, the study showed that a significant reduction of regulatory T cells (Treg) and myeloid-derived suppressor cells (MDSC) in both the spleen and the tumor microenvironment were mediated solely by the Lm-LLO immunotherapy.

As a result, this treatment combination led to significant inhibition of tumor growth and prolonged survival/complete regression of tumors in treated animals.
Given the findings in the mouse model, additional studies were conducted to evaluate activity in human cells. In separate studies, Lm-LLO immunotherapy treatment was found to significantly upregulate surface PD-L1 expression on human monocyte-derived dendritic cells isolated from healthy volunteers.

“Previous studies with Lm-LLO immunotherapies have established the ability to combine with chemotherapy and radiation. Dr. Khleif’s data are first to show the potential of combining Advaxis constructs with promising immune modulator (PD-1) in active clinical development,” commented Dr. Petit.
About Advaxis, Inc.
Advaxis is a clinical-stage biotechnology company developing the next generation of immunotherapies for cancer and infectious diseases. Advaxis immunotherapies are based on a novel platform technology using live, attenuated bacteria that are bio-engineered to secrete an antigen/adjuvant fusion protein(s) that is designed to redirect the powerful immune response all human beings have to the bacterium to the cancer itself.

ADXS-HPV is currently being evaluated in four clinical trials for human papillomavirus (HPV)-associated cancers: recurrent/refractory cervical cancer (India), locally advanced cervical cancer (GOG/NCI U.S. study, Clinical Trials.gov Identifier NCT01266460), head & neck cancer (CRUK study, Clinical Trials.gov Identifier NCT01598792), and anal cancer (BrUOG study, Clinical Trials.gov Identifier NCT01671488). Pharmaceutical Journal Advaxis has over 15 distinct immunotherapies in various stages of development, developed directly by Advaxis and through strategic collaborations with recognized centers of excellence such as: the National Cancer Institute, Cancer Research – UK, the University of Pennsylvania, the Georgia Regents University Cancer Center, the Karolinska Institutet, and others.
