Inovio Publishes Patient Benefit Results From A Pilot Clinical Study in Recurrent Respiratory Papillomatosis (RRP), A Rare Disease Caused by HPV Infections

PR82736

PLYMOUTH MEETING, Pennsylvania, Feb. 4, 2020 /PRNewswire=KYODO JBN/ --

Inovio Pharmaceuticals, Inc. (NASDAQ: INO) today announced publication of data

from its pilot clinical study of INO-3106, a novel DNA therapy targeting human

papilloma virus type 6 (HPV 6) for the treatment of recurrent respiratory

papillomatosis (RRP), a rare and orphan disease, in the open access scientific

journal Vaccines (MDPI). The article, entitled "Immune Therapy Targeting E6/E7

Oncogenes of Human Papillomavirus Type 6 (HPV-6) Reduces or Eliminates the Need

for Surgical Intervention in the Treatment of HPV-6 Associated Recurrent

Respiratory Papillomatosis" details the clinical efficacy seen in a pilot

clinical study of two patients with RRP and is authored by Inovio and its

collaborators at University of Pennsylvania Medical School as well as The

Wistar Institute.

RRP is a rare, orphan, HPV-associated disease that can cause noncancerous tumor

growths leading to life-threatening airway obstructions, and occasionally

progresses to cancer. Currently, the disease is incurable and can only be

treated by surgery to remove the tumors, which temporarily restores the airway.

The tumor always recurs and the surgery must be repeated, usually multiple

times a year.

Study results demonstrated that INO-3106 generated immunogenicity and

engagement and expansion of an HPV 6-specific cellular response, including

cytotoxic T cells. The paper also showed that Inovio's immunotherapy allowed

two patients who previously required approximately two surgeries per year to

manage this disease to delay the need for surgery to a robust degree; with one

patient requiring no surgeries for over a year and a half (584 days surgery

free) and a second that remained surgery free for over two and a half years

(over 915 days surgery free).

For this study, Inovio employed INO-3106, targeting specifically HPV 6 caused

RRP. In order to evaluate and treat patients with RRP caused by both HPV 6 and

11, Inovio is developing a new product candidate which targets both HPV 6 and

11 named INO-3107. Inovio plans to advance INO-3107 into Phase 2 clinical

trials in the first half of 2020 as a novel first-in-class immunotherapy for

the treatment of RRP in both adult and pediatric populations.

Dr. J. Joseph Kim, Inovio's President and CEO, said, "We are pleased that the

highly regarded journal Vaccines has acknowledged Inovio's impressive RRP pilot

study results.  We are advancing rapidly to bring relief to RRP patients whose

treatment options today are limited to repetitive and invasive surgeries. We

look forward to initiating a Phase 2 human trial this year to evaluate

INO-3107, a potential life-changing DNA medicine for this rare disease."

About RRP

Recurrent respiratory papillomatosis (RRP) is a rare disease (estimated at

20,000 active cases in the U.S.) that is characterized by the growth of tumors

in the respiratory tract caused by the human papilloma virus. Although benign,

papillomas can cause severe, even life-threatening airway obstruction and

respiratory complications. A distinguishing aspect of this disease is the

tendency for the papilloma to recur after surgical procedures to remove them.

Left untreated, if RRP develops in the lungs, affected individuals can

potentially experience recurrent pneumonia, chronic lung disease

(bronchiectasis) and, ultimately, progressive pulmonary failure. In extremely

rare cases (i.e. less than 1% of cases), papillomas can become cancerous

(malignant transformation) developing into squamous cell carcinoma. Additional

symptoms of RRP can include hoarse voice, difficulty in sleeping and

swallowing, and chronic coughing. RRP symptoms are more severe in children than

in adults. In children, the disorder is most often diagnosed between the ages

of 2-4. In adults, the disorder occurs most often in the third or fourth decade.

About Inovio Pharmaceuticals, Inc.

Inovio is a biotechnology company focused on rapidly bringing to market

precisely designed DNA medicines to treat, cure and/or protect people from

diseases associated with HPV, cancer, and infectious diseases. Inovio is the

first and only company to have clinically demonstrated that a DNA medicine can

be delivered directly into cells in the body via a proprietary smart device to

safely produce a robust immune response to destroy and clear high-risk HPV 16

and 18, which are responsible for 70% of cervical cancer, 90% of anal cancer

and 69% of vulvar cancer. In addition to HPV, Inovio's optimized plasmid design

and delivery technology has been demonstrated to consistently activate robust

and fully functional T cell and antibody responses against targeted cancers and

pathogens. Inovio's most advanced clinical program, VGX-3100, is in Phase 3

development for the treatment of HPV-related cervical pre-cancer. Also in

development are Phase 2 immuno-oncology programs targeting HPV-related cancers

and GBM, as well as externally funded platform development programs in Zika,

MERS, Lassa, and HIV. Partners and collaborators include ApolloBio Corporation,

AstraZeneca, The Bill & Melinda Gates Foundation, Coalition for Epidemic

Preparedness Innovations (CEPI), Defense Advanced Research Projects Agency,

GeneOne Life Science, HIV Vaccines Trial Network, Medical CBRN Defense

Consortium (MCDC), National Cancer Institute, National Institutes of Health,

National Institute of Allergy and Infectious Diseases, Regeneron,

Roche/Genentech, University of Pennsylvania, Walter Reed Army Institute of

Research, and The Wistar Institute. For more information, visit www.inovio.com.
