"Ovarian cancer is one of the most aggressive forms of cancer," said Professor Ignace Vergote, Chairman of the Department of Obstetrics and Gynaecology and Gynaecologic Oncology at the Catholic University of Leuven, European Union. "Most ovarian cancer patients are diagnosed at an advanced stage, which makes the disease difficult to treat. Current treatment options are not enough for these patients. We are pleased to begin this trial that has the potential to improve survival in recurrent ovarian cancer."

INNOVATE-3, a prospective, open-label study, will include 540 patients with recurrent, platinum-resistant ovarian cancer. Patients will be randomized to receive either weekly paclitaxel alone or weekly paclitaxel in combination with Tumor Treating Fields tuned to 200 kHz until progression. The primary endpoint is overall survival. Secondary endpoints include progression free survival, objective response rate, severity and frequency of adverse events, time to undisputable deterioration in health-related quality of life or death, and quality of life. Patients may have had a maximum of two prior lines of systemic therapy following diagnosis of platinum-resistance.

Novocure developed the trial design for INNOVATE-3 after learning the results of its phase 2 pilot trial of Tumor Treating Fields in combination with weekly paclitaxel, the INNOVATE trial. In 31 evaluable patients, the INNOVATE trial suggested a more than doubling of progression free survival and an improvement in overall survival among patients who received Optune with paclitaxel compared to paclitaxel alone.

"INNOVATE-3 is Novocure’s fourth phase 3 pivotal trial beyond glioblastoma, demonstrating our commitment to developing Tumor Treating Fields for a variety of solid tumors," said Asaf Danziger, Novocure’s Chief Executive Officer. "At Novocure, we strive to extend survival in some of the most aggressive forms of cancer. Ovarian cancer has been an important area of focus for our research because of the great unmet need faced by these patients. We are now working closely with trial sites and institutional review boards to open sites and enroll patients as quickly as possible."

Financial Year 2018 and Corporate Development Highlights

·On December 13, 2018, Y-mAbs announced the appointment of Dr. Gérard Ber, PhD to its board of directors, and the planned departure of Dr. Michael Buschle, PhD. Dr. Ber most recently served as Chief Operating Officer of Advanced Accelerator Applications SA, which he co-founded in 2002. Dr. Ber brings over 30 years of experience in molecular nuclear medicines, including development, production and commercialization of diagnostics and therapeutic products for several indications in oncology, cardiology, neurology and infectious/inflammatory diseases.

·On December 10, 2018, Y-mAbs announced FDA clearance of the IND for the Company’s humanized bispecific GD2 antibody. The IND was submitted by Memorial Sloan Kettering Cancer Center, who has licensed the antibody to Y-mAbs. A Phase 1/2 clinical trial has been initiated for patients with relapsed/refractory neuroblastoma, high grade osteosarcoma and other GD2(+) solid tumors, where patients have relapsed or refractory disease that is resistant to standard therapy. Y-mAbs expects that this bispecific GD2 antibody may have potential advantages over other bispecific antibodies, such as improved potency due to bivalency, binding to neonatal Fc receptor and longer serum half-life, which obviates continuous infusion and enables more convenient administration to the patient.

·On November 1, 2018, Y-mAbs announced that that Dr. Jeong A Park from the Department of Pediatrics of Memorial Sloan-Kettering Cancer Center would present preclinical data from the Company’s bispecific GD2 antibody at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting. Bispecific GD2 antibodies were tested in solid tumors in preclinical models with T-cells and were shown to exert anti-tumor effect against GD2(+) tumor xenografts or PDX tumors. Further, the bispecific GD2 antibodies induced rapid and quantitative T-cell homing to tumors, mediating antibody dependent T-cell mediated cytotoxicity (ADTC) against GD2, and were shown to infiltrate tumors with little to no immune response, also known as cold tumors.

·On October 23, 2018, Y-mAbs announced that the Committee for Orphan Medicinal Products of the European Medicines Agency recommended the granting of orphan medicinal product designation in the European Union for naxitamab for the treatment of relapsed or refractory high-risk neuroblastoma. Further, the positive opinion for orphan medicinal product designation had been sent to the European Commission, which subsequently granted the orphan drug designation.

·On September 25, 2018, Y-mAbs announced the closing of its initial public offering of 6,900,000 shares of its common stock, including the exercise in full of the underwriters’ option to purchase 900,000 additional shares of common stock, at a public offering price of $16.00 per share. The gross proceeds to Y-mAbs, before deducting underwriting discounts and commissions and estimated offering expenses payable by the Company, were approximately $110.4 million. All of the shares of common stock were offered by the Company, and Y-mAbs’ common stock is listed on The Nasdaq Global Select Market.

·On August 21, 2018, Y-mAbs announced that it had received Breakthrough Therapy designation for naxitamab, in combination with GM-CSF, for the treatment of high risk neuroblastoma refractory to initial therapy or with incomplete response to salvage therapy in patients older than 12 months of age with persistent, refractory disease limited to bone marrow with or without evidence of concurrent bone involvement.

· On July 10, 2018, Y-mAbs announced that it had entered into an exclusive sublicense with MabVax Therapeutics for its patented neuroblastoma vaccine, which is a bi-valent ganglioside based vaccine intended to treat neuroblastoma. The neuroblastoma vaccine was originally developed by Memorial Sloan Kettering Cancer Center and licensed to MabVax as part of a portfolio of anti-cancer vaccines. MabVax was granted Orphan Drug Designation for the vaccine. Under the terms of the sublicense, the Company has agreed to pay MabVax up to $1.3 million, consisting of an upfront payment of $700,000, and an additional payment of $600,000 on the first anniversary of the sublicense.

·On April 16, 2018, Y-mAbs announced positive Phase I data from treatment with omburtamab in Desmoplastic Small Round Cell Tumor (DSRCT), which is a rare sarcoma of adolescents and young adults. The phase I study of radioiodinated omburtamab was conducted at Memorial Sloan Kettering Cancer Center evaluate toxicity, pharmacokinetics, biodistribution and efficacy. A total of 41 DSRCT patients were treated with escalated doses of intraperitoneal omburtamab as radioimmunotherapy, and the compound had a satisfactory safety profile and appeared to have activity against micro-metastatic DSRCT.

Financial Results

Y-mAbs reported a net loss of $43.3 million, or $1.50 per basic and diluted share, for the financial year 2018 compared to a net loss of $19.2 million, or $0.99 per basic and diluted share for 2017.

OOG is an independent scientific group devoted to clinical ophthalmic oncology and related basic-science research.
Update #2. The Company will host a round table involving metastatic uveal melanoma patients at CURE OM’s Eyes on a Cure: Patient & Caregiver Symposium in Raleigh, North Carolina from April 5-7. The Community United for Research and Education of Ocular Melanoma (CURE OM) is the Melanoma Research Foundation’s initiative to increase awareness, education, and research funding for ocular melanoma, while improving the lives of people affected by this disease.

Ocular melanoma is a general category of melanoma disease affecting the eye and orbit. Its most common form, uveal melanoma, is an intraocular affliction originating in melanocytes in the iris, ciliary body, or choroid. Together with melanomas that form in the conjunctiva, cornea, retina, and orbit, these melanomas constitute ocular melanoma. Approximately half of ocular melanoma patients develop metastatic disease despite successful treatment of their primary tumors. Metastatic disease has historically been, and remains, generally fatal.

About Metastatic Uveal Melanoma

Uveal melanoma is a rare disease that is biologically and clinically distinct from cutaneous melanoma.5,6 Nearly 50% of uveal melanoma patients develop metastatic disease, with 80-90% of them presenting with liver as the first site of disease involvement.5,6,7 Outcomes of metastatic uveal melanoma are poor, with a median overall survival of 12 months.8

About PV-10

Provectus’ lead investigational oncology drug, PV-10, the first small molecule oncolytic immunotherapy, can induce immunogenic cell death. PV-10 is undergoing clinical study for adult solid tumor cancers, like melanoma and cancers of the liver, and preclinical study for pediatric cancers. In February 2019, orphan drug designation status was granted to PV-10 by the U.S. Food and Drug Administration for the treatment of ocular melanoma.
