Data From Stage 1 of a Phase 2 Study Conducted by GOG Presented at AGOS 2015
Advaxis to Host Conference Call and Webcast Today, September 17, at 4:30 p.m. ET, to Discuss Stage 1 Data
PRINCETON, N.J., Sept. 17, 2015 (GLOBE NEWSWIRE) -- Advaxis, Inc. (ADXS), a clinical-stage biotechnology company developing cancer immunotherapies, and the Gynecologic Oncology Group (GOG, now part of NRG Oncology), today announced clinical data from Stage 1 of an ongoing two-stage Phase 2 study (GOG-0265) of Advaxis's lead Lm Technology(TM) immunotherapy, axalimogene filolisbac (ADXS-HPV), in patients with persistent or recurrent metastatic (squamous or non-squamous cell) carcinoma of the cervix (PRmCC) who have progressed on at least one prior line of systemic therapy. The Stage 1 data showed that treatment with axalimogene filolisbac resulted in a 38.5 percent 12-month overall survival rate in 26 patients.
Evaluation of safety data showed that Grade 1 or 2 adverse events occurred in 19 out of 26 patients (73 percent), with fatigue, chills and fever being the most common. Four patients (15 percent) experienced a Grade 3 adverse event (hypotension and cytokine release syndrome) and one patient (4 percent) experienced a Grade 4 adverse event (lung infection and sepsis). The results were presented at the American Gynecological & Obstetrical Society (AGOS) annual meeting in Half Moon Bay, Calif. by Tom Herzog, M.D., Clinical Director at the University of Cincinnati Cancer Institute.
"Patients with PRmCC who have failed at least one line of therapy face a life threatening condition with an estimated survival of 4 to 7 months and no available treatment options," said Dr. Herzog. "The Stage 1 results for axalimogene filolisbac, which show 12-month survival, are a meaningful step forward in meeting the needs of women who require second-line treatment for PRmCC."
The GOG has conducted over 17 studies of a diverse set of investigational agents and regimens, but never has the 12-month overall survival rate exceeded 30 percent in people with PRmCC. Stage 2 of the GOG-0265 study is currently enrolling and the protocol has been amended by GOG to allow for continuous cycles of treatment until disease recurrence (the Stage 1 protocol provided for 3 doses of axalimogene filolisbac over 3 months).
"The axalimogene filolisbac data presented at AGOS by the GOG and Dr. Herzog represent some of the most encouraging Phase 2 data to date in metastatic cervical cancer and support the results previously observed in Advaxis's own Phase 2 study," said Daniel J. O'Connor, President and Chief Executive Officer of Advaxis. "Advaxis is grateful to NRG Oncology and the GOG for having the foresight several years ago to design, sponsor and conduct this study."
Advaxis has submitted a Special Protocol Assessment (SPA) request to the U.S. Food and Drug Administration (FDA) for a Phase 3 study evaluating the safety and efficacy of axalimogene filolisbac in high-risk, locally advanced cervical cancer (HRLACC). The SPA review process remains ongoing. The planned Phase 3 trial will be conducted in collaboration with the GOG Foundation, Inc. and is intended to begin enrollment by the end of 2015, depending on the length of the FDA's SPA review process.
A completed randomized Phase 2 trial of axalimogene filolisbac with or without cisplatin chemotherapy in Indian patients with PRmCC (0-2 prior lines of therapy) also demonstrated promising activity (12-month overall survival rate of 32 percent) and acceptable tolerability with chills and flu-like symptoms the most common treatment-related adverse events. Results from this trial were featured in a poster at the American Society of Clinical Oncology (ASCO) annual meeting in 2014.
Advaxis will hold a business update conference call today, September 17, at 4:30 p.m. ET/ 1:30 p.m. PT to provide Advaxis investors and stakeholders with a review of the Stage 1 clinical data from the GOG-0265 study presented at AGOS 2015. Dr. Herzog will be the featured presenter on the call.
A live broadcast of the conference call will be available by direct dial at 1-888-364-3109 in the U.S. or 1-719-325-2455 outside of the U.S, or by live webcast with slides available online at this URL: http://public.viavid.com/index.php?id=116099.
The call will be recorded and available for playback through October 1 by dialing 1-877-870-5176 in the U.S. and 1-858-384-5517 outside of the U.S.; Replay Passcode 2197270. In addition, the webcast will be available for replay at the URL above.
About the GOG-0265 Study
GOG-0265 is an open-label, single-arm, two-stage Phase 2 study designed to evaluate the safety, tolerability and efficacy of axalimogene filolisbac in approximately 67 patients with PRmCC who have received at least one prior line of systemic therapy. The primary efficacy endpoint is 12-month overall survival rate, with secondary efficacy endpoints of progression-free survival, overall survival and objective tumor response. The primary safety endpoints are the number of patients with dose-limiting toxicities and the frequency and severity of adverse effects.
The trial is being conducted in the United States by GOG, now part of NRG Oncology, under the sponsorship of the Cancer Therapy Evaluation Program (CTEP) of the National Cancer Institute (NCI). Further information about the study can be found on ClinicalTrials.gov, using Identifier NCT01266460.
About Cervical Cancer
Cervical cancer is the fourth most common cancer and the most common cause of mortality in women worldwide. In the United States, nearly 13,000 new cases are diagnosed and approximately 4,100 deaths are reported because of cervical cancer. According to the WHO/ICO Information Centre on HPV and Cervical Cancer, about 3.9 percent of women in the U.S. are estimated to harbor high-risk cervical HPV infection at a given time, and 71.7 percent of invasive cervical cancers are attributed to high-risk HPV strains.
About Axalimogene Filolisbac
Axalimogene filolisbac (ADXS-HPV) is Advaxis's lead Lm Technology(TM) immunotherapy candidate for the treatment of HPV-associated cancers and is in clinical trials for three potential indications: invasive cervical cancer, head and neck cancer, and anal cancer. In a completed randomized Phase 2 study in recurrent/refractory cervical cancer, axalimogene filolisbac showed apparent prolonged survival, objective tumor responses, and a manageable safety profile alone or in combination with chemotherapy, supporting further development of the company's Lm Technology(TM).
