PLYMOUTH MEETING, Pa., Aug. 06, 2018 (GLOBE NEWSWIRE) -- Inovio Pharmaceuticals, Inc. (NASDAQ: INO ) today announced that it has entered into a partnership with the AIDS Malignancy Consortium (AMC) to evaluate VGX-3100, Inovio’s immunotherapy for treating HPV-associated precancerous conditions in HIV-positive adult men and women. AMC will fund a Phase 2 clinical trial to evaluate the efficacy of VGX-3100 in adult men and women with human papillomavirus (HPV)-related high-grade anal dysplasia or squamous intraepithelial lesions (ASIL) and HIV. Recruitment is already ongoing for patients who are HIV-positive with histologically confirmed anal high-grade squamous intraepithelial lesions (HSIL) associated with HPV-16 and/or HPV-18. The multi-site Phase 2 study is planning to enroll approximately 75 patients who will receive four doses of VGX-3100. Financial details of the agreement were not disclosed.
Joel M. Palefsky, MD, Professor of Medicine, Division of Infectious Diseases, UCSF, and founder and chair of the HPV Working Group of the NCI AIDS Malignancy Consortium, said, “The incidence of anal cancer among HIV-positive men and women is unacceptably high. Better methods to treat the anal cancer precursor, known as anal high-grade squamous intraepithelial lesions (HSIL), are needed in an effort to prevent progression from HSIL to cancer. Given the encouraging results with VGX-3100 in treatment of cervical HSIL, the AMC looks forward to testing the immunotherapy for treatment of anal HSIL in this population.”
Dr. J. Joseph Kim, Inovio's President and CEO, said, “Expanding VGX-3100 to treat anal dysplasia represents a significant increase in commercial potential for our lead product. We thank the AMC for partnering with us to test the efficacy of VGX-3100 in a patient community where there is a great unmet need for a successful therapy. For these patients and others, Inovio is moving forward to become the ‘go-to’ immunotherapeutic solution provider for all major diseases caused by HPV, including cervical, vulvar and anal precancers.”
This open-label, multi-center Phase 2 study is designed to evaluate the safety and efficacy of VGX-3100 administered by intramuscular (IM) injection with CELLECTRA® delivery system in adult men and women who are HIV-positive with anal HSIL associated with HPV-16 and/or HPV-18. For additional information about the study, please visit www.clinicaltrials.gov (search identifier NCT03603808).
Separately, Inovio has already initiated a multi-center Phase 2 study designed to evaluate the safety and efficacy of VGX-3100 in 24 HIV-negative patients with anal HSIL associated with HPV-16 and/or HPV-18. The first patient was dosed in July.
Anal HSIL can lead to HPV-associated squamous cell carcinoma of the anus (SCCA). Anal cancer is uncommon in the general population, but its incidence is considerably increasing and is higher among HIV-positive men and women than in HIV-negative persons. The risk of SCCA among HIV-positive men has continued to increase even after the introduction of highly active antiretroviral therapy. Currently, rates of SCCA in HIV-positive men are higher than cervical cancer reported anywhere in the world. This trend is likely to continue with the aging of the HIV-positive population.
Anal cancer is estimated to have nearly 8,600 new cases diagnosed and cause more than 1,100 deaths in the United States in 2018. Currently, the only treatments for anal dysplasia consist of surgical excision, electro-cautery or laser therapy, but more than 50% of those treated with these current treatments experience recurrence of the disease. The HIV population has a significant burden of existing disease which cannot be addressed by current prophylactic approaches.
About the AIDS Malignancy Consortium
The AIDS Malignancy Consortium (AMC) is a National Cancer Institute-supported clinical trials group founded in 1995 to support innovative trials for AIDS-related cancers. The AMC is composed of 36 Clinical Trials Sites worldwide, five Working Groups, an Administrative Office, a Statistical Office, and an Operations and Data Management Office. Collectively, these components develop and oversee the scientific agenda, manage the groups’ portfolio of clinical trials and other scientific-based studies, and help to develop new protocols. The AMC mission is to investigate new treatment and prevention interventions for malignancies in people living with HIV and to study the pathobiology of these tumors in the context of clinical trials.
About VGX-3100
VGX-3100 is a DNA-based immunotherapy under Phase 3 investigation for the treatment of HPV-16 and HPV-18 infection and precancerous lesions of the cervix. Inovio has also initiated open-label Phase 2 clinical trials evaluating its efficacy for treating HPV-related vulvar and anal precancers. VGX-3100 has the potential to be the first approved treatment for HPV infection of the cervix and the first non-surgical treatment for precancerous cervical lesions. VGX-3100 works by stimulating a specific immune response to HPV-16 and HPV-18, which targets the infection and causes destruction of precancerous cells. In a randomized, double-blind, placebo-controlled Phase 2b study in 167 adult women with histologically documented HPV 16/18 cervical HSIL (CIN2/3), treatment with VGX-3100 resulted in a statistically significantly greater decrease in cervical HSIL and clearance of HPV infection vs. placebo. The most common side effect was injection site pain, and no serious adverse events were reported. VGX-3100 utilizes the patient’s own immune system to clear HPV-16 and HPV-18 infection and precancerous lesions without the increased risks associated with surgery, such as loss of reproductive health and negative psychosocial impacts.
About Inovio’s DNA Immunotherapy Technology Platform
Inovio is advancing the medical potential of a unique class of immunotherapy technology. Its DNA-based platform, which is the foundation for all of Inovio’s products, including VGX-3100, is unique in its ability to leverage the body’s naturally existing mechanisms to generate robust, highly targeted immune responses to prevent and treat disease – and to do so in the body without harmful side effects. Its SynCon® immunotherapy design and CELLECTRA® delivery transform novel genetic blueprints into functional antibody and killer T cell responses. Inovio was the first to report the activation – in the body – of significant, antigen-specific functional T cells correlated to statistically significant efficacy in a placebo-controlled, randomized, double-blind Phase 2b clinical trial (HPV-related precancer), with a very favorable safety profile. These data were published in The Lancet and independently described as a “major breakthrough” in the field by U.S. National Cancer Institute scientists. Inovio has achieved significant antigen-specific immune responses against multiple diseases and is advancing a growing pipeline of cancer and infectious disease immunotherapies and vaccines.
