Dr. Algazi’s recently accepted presentation, entitled Intratumoral tavokinogene telseplasmid induces abscopal clinical responses in metastatic melanoma patients, will describe the OMS-100 Phase 2 multicenter, single-group study which evaluated the efficacy and safety observed after repeat dosing and different intervals between TAVO cycles. The primary endpoint was overall response rate (ORR) by modified "skin" Response Evaluation Criteria In Solid Tumors (mRECIST). Dr. Algazi, the primary investigator, is a leading expert in oncology research as well as a Clinical Strategic Advisor and a Clinical Advisory Board member for OncoSec.

The new data will demonstrate that local treatment with TAVO alone led to whole-body immune responses associated with regression of untreated lesions in half of the 50 patients treated on the study.

"We were grateful to Dr. Algazi and the Melanoma Bridge Conference for the opportunity to share this important TAVO monotherapy data demonstrating abscopal clinical responses with the clinicians, biotechnology executives, and industry opinion leaders in attendance," said Daniel J. O’Connor, OncoSec President and Chief Executive Officer. "Having Dr. Algazi present data from our OMS-100 study at the Melanoma Bridge Conference is an exciting opportunity for OncoSec as it serves to highlight our clinical work investigating TAVO as a monotherapy in the treatment of metastatic melanoma, as well as bring added visibility to our Phase 2b PISCES/KEYNOTE-695 clinical trial combining TAVO with pembrolizumab in metastatic melanoma for patients that have failed all available treatment options, including anti-PD-1 immunotherapy."

Details of the presentation are as follows:

On October 2, 2018 Tocagen Inc. (Nasdaq: TOCA) reported it has received Protocol Assistance from the European Medicines Agency (EMA) under the Company’s PRIME (PRIority MEdicines) designation for Toca 511 (vocimagene amiretrorepvec) & Toca FC (flucytosine, extended-release) for the treatment of patients with recurrent high grade glioma (HGG) (Press release, Tocagen, OCT 2, 2018, View Source;p=RssLanding&cat=news&id=2369807 [SID1234529957]). In particular, the EMA indicated that the statistical analyses, seamless design, and the use of overall survival as the primary endpoint in the ongoing Phase 3 Toca 5 clinical trial are appropriate for a potential marketing authorization application for Toca 511 & Toca FC.

"We are pleased the global Toca 5 trial has the potential to serve as the basis for a regulatory application in Europe, which we believe may expedite the advancement of Toca 511 & Toca FC as a treatment for patients with brain cancer. If the pivotal trial data are positive, our gene therapy would be the first medicine in over 20 years to show a treatment benefit in a randomized trial in patients with this disease," said Marty Duvall, chief executive officer of Tocagen. "Our interactions with the European regulators under the PRIME pathway are conducted in the spirit of collaboration and urgency to bring forward a new treatment for brain cancer as quickly as possible."

Toca 5 is an international, randomized, multi-center study evaluating the safety and efficacy of Toca 511 & Toca FC compared to standard of care in patients undergoing resection for recurrent HGG. The trial recently completed the planned enrollment of 380 patients. The primary endpoint of the trial is overall survival. Secondary endpoints of the Toca 5 trial include durable response rate, defined as complete or partial responses lasting at least 24 weeks, which is being assessed as a novel endpoint in the post-surgical setting of recurrent HGG. Tocagen plans to conduct a second interim analysis of Toca 5 in the first half of 2019 and the final planned safety and efficacy analyses by the end of 2019. More information about Toca 5 can be found on ClinicalTrials.gov using the clinical trial identifier NCT02414165.

The Committee on Orphan Medicinal Products (COMP) of the EMA has designated both Toca 511 & Toca FC as orphan medicinal products indicated for the treatment of glioma. In addition, the U.S. Food and Drug Administration granted Breakthrough Therapy Designation for Toca 511 & Toca FC in recurrent HGG.

Recurrent HGG is among the most common and aggressive primary brain cancers and often strikes in the prime of life. The two most common forms of HGGs are glioblastoma and anaplastic astrocytoma. The total number of new diagnoses of HGG expected in 2018 is about 197,000 worldwide, with approximately 38,000 in Europe. Unfortunately, HGG recurs in most patients after frontline treatment, and standard of care treatment typically offers a median survival of only seven to nine months.

About Toca 511 & Toca FC
Tocagen’s lead product candidate is a two-part cancer-selective immunotherapy comprising an investigational biologic, Toca 511, and an investigational small molecule, Toca FC. Toca 511 is a retroviral replicating vector (RRV) that selectively infects cancer cells and delivers a gene for the enzyme, cytosine deaminase (CD). Through this targeted delivery, only infected cancer cells carry the CD gene and produce CD. Toca FC is an orally administered prodrug, 5-fluorocytosine (5-FC), which is converted into an anti-cancer drug, 5-fluorouracil (5-FU), when it encounters CD. 5-FU kills cancer cells and immune-suppressive myeloid cells resulting in anti-cancer immune activation and subsequent tumor killing.

The 2018 Nobel Prize in Physiology or Medicine has been awarded jointly to James P. Allison and Tasuku Honjo for their almost 30 year old discovery of cancer therapy by inhibition of negative immune regulation. It was in the 1990s, when Dr James P. Allison’s laboratory at the University of California, Berkeley studied the T-cell protein CTLA-4. He was one of several scientists who had made the observation that CTLA-4 functions as a brake on T cells. In 1992, a few years before Allison’s discovery, Tasuku Honjo discovered PD-1, another protein expressed on the surface of T-cells. His research showed that PD-1, similar to CTLA-4, functions as a T-cell brake, but operates by a different mechanism.

Fast forwarding to today and cancer immunotherapy is the established 4th pillar of cancer therapy and encompasses a highly diverse portfolio of treatment strategies from the early interferon-α/interleukin-2 therapies to the current progress of immune-checkpoint inhibitors and CAR-T therapies to make the immune system fight cancer.

The first approved immune-checkpoint inhibitor was Bristol-Myers Squibb’s ipilimumab (Yervoy) back in 2011 for the treatment of adult patients with previously-treated advanced melanoma. Then followed the approval of Opdivo (nivolumab) and Keytruda (pembrolizumab) in rapid succession. Currently there are seven approved immune-checkpoint inhibitors for the treatment of sixteen different tumor types, see table below. Just last Friday Regeneron and Sanofi reported that the U.S. Food and Drug Administration (FDA) has approved Libtayo (cemiplimab-rwlc) for the treatment of patients with metastatic cutaneous squamous cell carcinoma (CSCC) or locally advanced CSCC who are not candidates for curative surgery or curative radiation.

These approved drugs are just the tip of the iceberg with more than 500 immune-checkpoint drugs being developed world-wide for the treatment of cancer. No less than twenty of these are in late stage development.

The event of immune-checkpoint drugs such as nivolumab (Opdivo) and pembrolizumab (Keytruda) have dramatically changed the possibility to harness the power of the immune system in fighting cancer not only as a monotherapy but, maybe more importantly, also as a combination therapy.
