"There remains a significant unmet medical need in oncology for patients in whom the existing PD-1 therapies do not work. Based on the encouraging data we presented at SITC (Free SITC Whitepaper), we believe the combination of ImmunoPulse IL-12 and pembrolizumab may offer a differentiated approach to reshaping the tumor microenvironment by converting immunologically cold tumors to hot," said Sharron Gargosky, Chief Clinical and Regulatory Officer of OncoSec. "We look forward to the continued advancement of this trial and to sharing data in 2018."

The Phase 2b, multicenter study of intratumoral tavo with electroporation in combination with intravenous pembrolizumab will enroll approximately 48 patients with a histological diagnosis of melanoma with progressive locally advanced or metastatic disease defined as Stage III or Stage IV. The primary endpoint will be the Best Overall Response Rate (BORR).

The Company’s prior Phase 2 OMS I-102 combination study of ImmunoPulse IL-12 and pembrolizumab in 22 patients unlikely to respond to anti-PD-1 therapy demonstrated a 50% best overall response rate and a 41% complete response rate. In addition, the trial showed a 57% progression free survival (PFS) rate at 15 months (median PFS not yet reached) and 100% (11/11) duration of response. In clinical studies to date, intratumoral tavo has demonstrated a favorable safety profile and has been well tolerated.

PISCES/KEYNOTE-695 is the second combination study conducted with pembrolizumab and, if successful, could form the basis for a BLA under the accelerated approval pathway.

About Metastatic Melanoma

Melanoma is a type of skin cancer that begins in skin cells called melanocytes. As the cancer progresses, melanoma becomes more difficult to treat once it spreads beyond the skin, such as the lymphatic system (metastatic disease). Given its occurrence in young individuals, the potential years of life lost to melanoma can be higher when compared with other cancers. Although melanoma is a rare form of skin cancer, it accounts for over 75% of skin cancer deaths. The American Cancer Society estimates that approximately 87,000 new melanoma cases and 10,000 deaths from the disease will occur in the United States in 2017. Additionally, the World Health Organization estimates that approximately 132,000 new cases of melanoma are diagnosed around the world every year.

About PISCES (Anti-PD-1 IL-12 Stage III/IV Combination Electroporation Study)/KEYNOTE-695

PISCES/KEYNOTE-695 is a global, multicenter phase 2b, open-label trial of intratumoral plasma encoded IL-12 (tavokinogene telseplasmid or "tavo") delivered by electroporation in combination with intravenous pembrolizumab in patients with stage III/IV melanoma who have progressed or are progressing on either pembrolizumab or nivolumab treatment. The Simon 2-stage study of intratumoral tavo plus electroporation in combination with pembrolizumab will enroll approximately 48 patients with histological diagnosis of melanoma with progressive locally advanced or metastatic disease defined as Stage III or Stage IV. The primary endpoint will be the Best Overall Response Rate (BORR).

Aura’s lead program, light-activated AU-011, is being developed for the treatment of primary ocular melanoma, a rare and life-threatening disease with no approved FDA therapies, and is currently in Phase 1b/2 clinical testing. Researchers believe AU-011’s high tumor specificity and targeting capability, due to its ability to selectively bind to heparan sulfate proteoglycans (HSPG) on the surface membrane of tumor cells, may be key to avoiding damage to the main ocular structures and preserving patients’ vision

"These data offer strong support for the basis of our clinical program, which we are currently investigating in patients with primary ocular melanoma," said Elisabet de los Pinos, Ph.D., founder and CEO of Aura. "Our ultimate goal is to offer a first-line treatment option that can achieve local tumor control, while enabling patients to maintain their vision."

Currently available treatment options to control local tumor growth, such as plaque radiotherapy, are highly invasive and not tumor-specific, often resulting in severe and vision-threatening complications. The data published today suggest that AU-011 may be further investigated as a novel first-line treatment option that can enable early intervention and potentially become the standard of care for patients with early-stage ocular melanoma.

About ocular melanoma
Ocular melanoma, also known as uveal or choroidal melanoma, is a rare and aggressive eye cancer. Ocular melanoma is the most common primary ocular tumor and develops in the uveal tract of the eye. No targeted therapies are available at present, and current radiotherapy treatments can be associated with severe visual loss and other long-term sequelae such as dry eye, glaucoma, cataracts and radiation retinopathy. The most common current treatment is plaque radiotherapy, which involves surgical placement of a radiation device against the exterior of the eye over the tumor. This technique can control the melanoma but can also lead to radiation-related cataract, retinopathy, optic nerve damage and loss of vision. The alternative is enucleation, or removal of the eye. Ocular melanoma metastasizes to the liver in about 40 percent of cases in the long-term (source: OMF), and only 15 percent of patients whose melanoma has metastasized survive beyond five years after diagnosis (source: ACS).

About light-activated AU-011
AU-011 is a first-in-class targeted therapy in development for the primary treatment of ocular melanoma. The therapy consists of viral nanoparticle conjugates that bind selectively to unique receptors on cancer cells in the eye and is derived from technology originally pioneered by Dr. John Schiller of the Center for Cancer Research at the National Cancer Institute (NCI), recipient of the 2017 Lasker-DeBakey Award. Upon activation with an ophthalmic laser, the drug rapidly and specifically disrupts the membranes of tumor cells while sparing key eye structures, which may allow for the potential of preserving patients’ vision and reducing other long-term complications of treatment. This therapy can be delivered using equipment commonly found in the ophthalmologist’s office and does not require a surgical procedure, pointing to a potentially less invasive, more convenient therapy for patients and physicians. AU-011 for ocular melanoma has been granted orphan drug and fast track designations by the U.S. Food and Drug Administration and is currently in clinical development.
