Company-sponsored studies:
FOCUS for platinum-resistant ovarian cancer
FOCUS is a phase 2/3 study in patients with platinum-resistant ovarian cancer, evaluating whether the addition of CA4P to the current standard-of-care (bevacizumab plus chemotherapy) improves progression-free survival. As of June 9, 2017, FOCUS has enrolled 57 patients in the United States, Germany and Belgium, with enrollment on-going at 37 sites. The second interim analysis, which will occur after the first 40 patients have been treated for at least two months or withdrawn from the study, remains on track to be completed in August 2017. Based on the number of patients enrolled and projected enrollment trends, the company expects the third interim analysis, representing 60 patients, to be completed in late September 2017.

OX1222 for acute myeloid leukemia
OX1222 is a dose-ascending phase 1b/2 clinical trial evaluating OXi4503 in combination with cytarabine in patients with recurrent/relapsed acute myeloid leukemia (AML). Mateon recently completed enrollment and treatment for the fourth cohort of 7.81 mg/m2 of OXi4503, and no dose limiting toxicities or significant safety issues were identified among the three patients. One patient treated in the fourth cohort experienced a significant AML blast reduction, with blast counts going from 89% upon enrollment to 7% following the first cycle of treatment. However, the patient subsequently experienced an unrelated adverse event and withdrew from the study approximately two weeks after the last dose of OXi4503 in the second cycle of treatment, prior to an additional blast measurement and accordingly did not meet the criteria for a complete remission. Three complete remissions were observed in the first three cohorts (19% overall in the clinical trial to date), each of which occurred after two cycles of treatment, and two complete remissions remain on-going at 12+ and 3+ months. Enrollment is on-going in the fifth cohort of 9.76 mg/m2 of OXi4503.

Investigator-sponsored studies:
PAZOFOS for recurrent ovarian cancer
The PAZOFOS study is a phase 1b/2 investigator-sponsored study being conducted in the U.K., evaluating the combination of CA4P and the TKI-inhibitor pazopanib for patients with advanced recurrent ovarian cancer. To date, the study has enrolled and treated 20 patients with CA4P and pazopanib in the phase 1b and phase 2 portions of the trial. The study sponsor, The Christie NHS Trust, has temporarily suspended enrollment in the trial in order to collect and review additional information on two recent serious adverse events – one patient in the study experienced hypertension and myocardial ischemia, and a second patient experienced chest pain. In both cases, the events were of short duration and the clinical symptoms resolved.

The label for pazopanib, which is not approved for the treatment of ovarian cancer in the U.S., contains warnings for cardiac dysfunction, arterial thrombotic events and hypertension. CA4P has been observed in most patients to cause an acute and transient increase in blood pressure following administration.

Following review of the data available for the patients in PAZOFOS, the company does not believe any changes or adjustments to Mateon’s FOCUS study are warranted. FOCUS has restrictive enrollment criteria for patients with pre-existing cardiovascular risk factors and specific algorithms for treatment of patients that experience blood pressure increases.

Neuroendocrine tumors
The Markey Cancer Center at the University of Kentucky recently began a phase 1 study evaluating the combination of CA4P and everolimus for the treatment of neuroendocrine tumors. In the first part of the study, patients are being treated with two different dosing regimens of CA4P in combination with everolimus to evaluate the safety of the drug combination and establish appropriate CA4P dosing levels.

"We are pleased that studies in both our core programs, the FOCUS study of CA4P for platinum-resistant ovarian cancer and Study OX1222 of OXi4503 for AML, are enrolling well and showing a good safety profile, as well as initial indications of efficacy," stated William D. Schwieterman, M.D., President and Chief Executive Officer of Mateon. "We are looking forward to data read outs from each of these studies later this summer."

"The investigator-sponsored PAZOFOS study, which uses CA4P with a different combination of drugs for recurrent ovarian cancer, also holds significant potential for patients and we’re hopeful that enrollment will resume soon," Dr. Schwieterman added.

On June 8, 2017 Inovio Pharmaceuticals, Inc. (NASDAQ:INO) reported that it has commenced its phase 3 clinical program to evaluate the efficacy of Inovio’s DNA-based immunotherapy, VGX-3100, to treat cervical dysplasia caused by human papillomavirus (HPV) (Press release, Inovio, JUN 8, 2017, View Source [SID1234519479]). Inovio’s study will assess the efficacy of VGX-3100 in regressing cervical HSIL (high-grade squamous intraepithelial lesions), a direct precursor to cervical cancer, and eliminating the HPV infection that causes these lesions. The pivotal data from this program will support the potential licensure of VGX-3100 as the first immunotherapy for this disease.

Inovio satisfied the FDA’s request for information relating to its CELLECTRA 5PSP delivery device, resulting in the FDA removing the clinical hold on this program. Inovio plans to immediately begin recruiting patients for the phase 3 trial.

Inovio’s phase 3 program, named REVEAL (Randomized Evaluation of VGX-3100 and Electroporation for the Treatment of Cervical HSIL), will consist of a primary study (REVEAL 1) and confirmatory study (REVEAL 2), as per FDA general guidance for phase 3 programs, to be conducted in parallel. The studies will each enroll 198 patients in more than 100 study centers globally. Mark Einstein, MD, MS, FACS, FACOG, Professor and Chair Department of Obstetrics, Gynecology and Women’s Health Assistant Dean, Clinical Research Unit, Rutgers New Jersey Medical School, is Principal Investigator for the studies.

The REVEAL studies are prospective, randomized (2:1), double-blind, placebo-controlled trials evaluating adult women with HPV 16/18 positive biopsy-proven cervical HSIL, otherwise known as cervical intraepithelial neoplasia (CIN) 2 or 3. The primary endpoint is regression of cervical HSIL AND virologic clearance of HPV-16 and/or HPV-18 in the cervix. The studies will evaluate cervical tissue changes at approximately 9 months after beginning a three dose regimen of VGX-3100 administered at months 0, 1, and 3. Secondary endpoints include safety; tolerability; regression of CIN 2/3 to CIN 1 or normal; virologic clearance of HPV; efficacy measured by non-progression to cancer; and clearance of HPV from non-cervical anatomic locations.

VGX-3100 has the potential to be the first treatment for HPV infection of the cervix and the first non-surgical treatment for pre-cancerous cervical lesions. VGX-3100 stimulates a specific immune response to HPV-16 and HPV-18, targeting the infection and destroying pre-cancerous cells. There are no treatments available for HPV infection and surgery is the only approved treatment for cervical HSIL. While surgery is effective at removing dysplastic lesions, it does not treat the underlying HPV infection and carries increased risk of cervical incompetence and pre-term birth, which can result in fetal morbidity and mortality. VGX-3100 demonstrated in a phase 2b study (published in The Lancet) its ability to clear HPV-16 and HPV-18 infection and pre-cancerous lesions.

Dr. Mark Bagarazzi, Inovio’s Chief Medical Officer, said, "Despite the availability of preventive HPV vaccines for over a decade, HPV-related cervical HSIL and cancers remain a widely prevalent problem. Unfortunately, current treatments are invasive and do not address the underlying HPV infection. VGX-3100 has the potential to be a first-in-class HPV-specific immunotherapy offering women the prospect of preventing cervical cancer without undergoing an invasive surgical procedure that may compromise their reproductive health. We are pleased to be able to immediately begin recruiting patients at the first 15 sites by the end of this month."

Dr. J. Joseph Kim, Inovio’s President and CEO, said, "Initiating our REVEAL phase 3 program marks a milestone for Inovio, for the next generation of DNA-based immunotherapies, and for women’s health. Combining this first phase 3 program with our previously announced phase 2 clinical trial of VGX-3100 for HPV-related vulvar neoplasia and our checkpoint inhibitor-based combination study with MedImmune/AstraZeneca targeting HPV associated cancers, Inovio is well positioned to comprehensively treat HPV-associated diseases across the continuum of HPV infection through to cancer in both men and women. Adding our recently announced collaborative immuno-oncology combination studies with Regeneron and Genentech, 2017 is a transformative year that is laying the foundation for multiple opportunities for important efficacy data."

About HPV and Cervical HSIL

HPV is the most common sexually transmitted infection, with over 14 million new infections annually. While many of these are transient infections, persistent high-risk infections can cause the formation of pre-cancerous lesions. Left untreated, women diagnosed with cervical HSIL are at increased risk of developing cervical cancer. HPV types 16 and 18 are responsible for 70% of cervical cancers, with more than 400,000 new cases of HPV 16/18 cervical HSIL annually in the US and Europe. Cervical cancer is a major global health problem, causing 260,000 deaths annually. While cervical HSIL and cervical cancer are the most well-known HPV related diseases, HPV is also a major cause of HSIL and cancer in the entire anogenital region and oropharynx. Currently there are no treatments available for HPV infection and surgery is the only approved treatment for cervical HSIL. While surgery is effective at removing lesions, it does not treat the underlying HPV infection and it carries increased risk of cervical incompetence and pre-term birth, which can result in fetal morbidity and mortality.

About VGX-3100

VGX-3100 is a DNA-based immunotherapy under investigation for the treatment of HPV-16 and HPV-18 infection and pre-cancerous lesions of the cervix (phase 3) and vulva (phase 2). VGX-3100 has the potential to be the first approved treatment for HPV infection of the cervix and the first non-surgical treatment for pre-cancerous 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 pre-cancerous 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 pre-cancerous lesions without the increased risks associated with surgery, such as loss of reproductive health and negative psychosocial impacts.

On June 8, 2017 2X Oncology, Inc. ("2X" or the "Company"), a precision medicine company developing targeted therapeutics to address significant unmet needs in women’s cancer, reported that it has obtained the Investigational New Drug (IND) application for 2X-111 (doxorubicin hydrochloride and glutathione) from 2-BBB Medicines B.V., assuming all future development and ownership of the drug (Press release, 2X Oncology, JUN 8, 2017, View Source [SID1234526104]).

2X-111 is being developed as a new treatment option for women with brain metastases from breast cancer and for patients with recurrent glioblastoma multiforme (GBM), an orphan-designated condition.

George O. Elston, CEO of 2X Oncology, said, "Having this IND in place is an important step as we focus on initiating Phase 2 clinical trials of 2X-111 in GBM and brain metastases from breast cancer later this year.

"These studies will employ our proprietary DRP companion diagnostic to identify patients based on their unique tumor mRNA expression and treat those most likely to respond to and benefit from therapy," Mr. Elston added.

"Patient selection based on the unique genetic properties of a tumor is an important new direction in the treatment of cancer, and we are pleased to have this capability for our programs and patients."

The Drug Response Predictor (DRP) technology utilizes messenger RNA (mRNA) from patient biopsies and uses proprietary analytics to create a unique fingerprint of relevant genes based on a tumor’s sensitivity, or resistance, to a compound. DRPs are specific for each product and have been validated in over 40 clinical studies.

"We expect data from these studies in 2018 which, if positive, can position this program for possible accelerated approval filings shortly thereafter," Mr. Elston concluded.

Formerly known as 2B3-101, 2X-111 improves on commercially available PEGylated liposomal doxorubicin products with an additional glutathione coating that safely enhances drug delivery across the blood-brain barrier. Doxorubicin is an anthracycline that inhibits the growth of many cancerous cell lines, including glioblastoma and breast cancer cell lines. It is among the most widely used anti-cancer agents.

An abstract on the predictive ability of the DRP in treating advanced breast cancer with a similar anthracycline, epirubicin, was presented in a poster session at the 2017 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting.

The abstract describes a retrospective-prospective blinded study which evaluated the ability of the DRP to predict the efficacy of epirubicin in a cohort of 135 metastatic breast cancer patients. The DRP was significantly associated with progression free survival in this study. The estimated median time to progression for a patient with a DRP value of 25% was 7 months, versus 13 months for a patient with a DRP value of 75%.

Mr. Elston will discuss 2X-111 and other 2X pipeline drugs at the Jefferies 2017 Global Healthcare Conference on June 9, 2017, at 10:00am EDT. The presentation will be available as a live webcast and archived for post-listening on the Company’s website.

About Breast Cancer Brain Metastases

Breast cancer is the second most common common cause of brain metastases, with metastases occurring in 10–16 % of patients[1]. Patients who develop brain metastases tend to have poor prognosis with short overall survival. Furthermore, brain metastases are a major cause of morbidity, associated with progressive neurologic deficits that result in a reduced quality of life.

About Glioblastoma Multiforme
Glioblastoma multiforme (GBM) is the most common class of malignant primary brain tumors and one of the most aggressive forms of cancer. This highly invasive and proliferative cancer resists standard chemotherapy and radiotherapy. Current therapeutic strategies for the treatment of GBM fail to demonstrate adequate efficacy and/or are generally palliative. Median overall survival is 12 to 14 months
