The European Medicines Agency Grants Orphan Drug Designation Status to Immunovaccine's DPX-Survivac in Ovarian Cancer

HALIFAX, NOVA SCOTIA--(Marketwired - Nov. 22, 2016) - Immunovaccine Inc. ("Immunovaccine" or the "Company") (TSX:IMV)(OTCQX:IMMVF), a clinical stage vaccine and immunotherapy company, today announced that the European Medicines Agency ("EMA") has granted 'Orphan Drug Designation' status to the Company's lead immuno-oncology product candidate, DPX-Survivac for the treatment of ovarian cancer in the European Union (EU).

The EMA grants Orphan Designation to medicines intended to treat, prevent or diagnose life threatening and debilitating disease, with a prevalence no greater than five in 10,000 in the EU and where no satisfactory method of treatment, prevention or diagnosis exists, unless the proposed medicine offers a significant benefit to those with the condition.

"As our recent clinical program has demonstrated, ovarian cancer-one of the most underserved cancers in today's treatment landscape-is a strong focus for Immunovaccine and, in particular, our DPX-Survivac program," said Gabriela Rosu, M.D., Chief Medical Officer of Immunovaccine. "We plan to leverage this important designation as we continue evaluating DPX-Survivac, with the goal of bringing a new option to patients fighting this disease."

According to recent EMA reports, ovarian cancer affects approximately 150,000 women at any given time in the European Union and has a prevalence of approximately three per 10,000. Following receipt of the 'Orphan Designation' status, drug developers can access a number of incentives, including protocol assistance, market exclusivity for a ten-year period following approval, and potential fee reductions. The receipt of Orphan Designation does not change the regulatory requirements or process for obtaining marketing approval.

DPX-Survivac activates and directs an immune response to the tumor antigen survivin, which is a protein found in tumors of more than 90 percent of ovarian cancer patients and is involved in multiple critical pathways of cancer cell growth and survival. The EMA granted DPX-Survivac this status following its review of Immunovaccine's pre-clinical and clinical data submission.

This designation marks one of several recent milestones for Immunovaccine's DPX-Survivac ovarian cancer program. The Company recently announced topline results of a Phase 1/1b clinical trial evaluating DPX-Survivac in ovarian cancer, which indicated that the product candidate was well tolerated, with no unexpected treatment-related serious adverse events (SAEs), and that it demonstrated the ability to generate a relevant, sustained immune response.

Previously, the U.S. Food & Drug Administration (FDA) granted DPX-Survivac Fast Track status as maintenance therapy in individuals with advanced ovarian, fallopian tube, and peritoneal cancer who have no measureable disease following surgery and front-line platinum/taxane chemotherapy to improve their progression-free survival. The FDA also granted Orphan Drug status to DPX-Survivac for the treatment of ovarian cancer. This FDA designation is valid for all applications of DPX-Survivac in ovarian cancer without restriction to a specific stage of disease.

About DPX-Survivac

DPX-Survivac is Immunovaccine's lead cancer immunotherapy candidate, generated by its novel proprietary DepoVax™ adjuvanting technology platform. DPX-Survivac consists of survivin-based peptide antigens formulated in the DepoVax™ adjuvanting platform. The National Cancer Institute (NCI) has recognized survivin as a promising tumor-associated antigen (TAA) because of its therapeutic potential and its cancer specificity. Survivin is broadly over-expressed in more than 20 solid tumors and blood cancers including ovarian, breast, colon and lung cancers. Survivin plays an essential role in antagonizing apoptosis, supporting tumor-associated angiogenesis, and promoting resistance to various anti-cancer therapies. Survivin is also a prognostic factor for many cancers and it is found in high percentage of cancer patients.

The DPX-Survivac vaccine is thought to work by eliciting a cytotoxic T cell immune response against cells presenting survivin peptides on HLA class I molecules. This targeted therapy attempts to use the immune system to actively search for tumor cells expressing survivin and destroy them.
