"Despite recent advances in the treatment of multiple myeloma, it remains an incurable disease with a need for active and well-tolerated agents," said Roger D. Dansey, M.D., Chief Medical Officer of Seattle Genetics. "BCMA is a validated therapeutic target for multiple myeloma. SEA-BCMA represents a novel empowered antibody treatment approach that has demonstrated antitumor activity and an acceptable safety profile in preclinical evaluation to date. We look forward to evaluating SEA-BCMA through our clinical development program and hope to meaningfully improve outcomes for multiple myeloma patients."

The phase 1 trial is an open-label, multi-center, dose-escalation and expansion clinical study designed to enroll approximately 65 patients with relapsed or refractory MM in the United States. The study is expected to be conducted in two parts, with a dose escalation cohort to evaluate safety and tolerability and to determine the maximum tolerated dose of SEA-BCMA, followed by an expansion cohort to obtain further data regarding safety and antitumor activity.

Data presented at the American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting 2018 demonstrate that SEA-BCMA exhibits encouraging preclinical antitumor activity and has the potential to be an active, tolerable and combinable agent.

About Multiple Myeloma

Multiple myeloma (MM) is an aggressive cancer that forms in white blood cells called plasma cells. Cancerous plasma cells can crowd out healthy blood cells, impair bone strength and weaken the immune system. MM is the second most common blood cancer in the United States. According to the American Cancer Society, more than 30,000 new cases of MM were expected in the U.S. in 2018, with over 12,500 deaths. Despite recent medical advances, MM still remains an incurable disease. It is managed with sequential lines of treatment that typically yield shorter durations of disease control with each subsequent relapse, and some patients receive more than four lines of treatment over the course of their disease.

About SEA-BCMA

SEA-BCMA is a novel investigational antibody empowered using Seattle Genetics’ proprietary Sugar Engineered Antibody (SEA) technology that leads to enhanced antibody dependent cellular cytotoxicity. SEA-BCMA is a non-fucosylated BCMA-directed antibody that is designed to block proliferative tumor cell signaling, mediate antibody dependent cellular phagocytosis and induce enhanced cell lysis through antibody dependent cellular cytotoxicity. The cell surface protein BCMA is expressed on cells of several cancer types, including multiple myeloma and other B-cell malignancies. BCMA is a validated therapeutic target for multiple myeloma.

"Several initiatives that we have been pursuing during the past quarter should bear fruit in the coming weeks and months," said Pierre Laurin, Prometic’s President and Chief Executive Officer. "We have implemented cost-control measures to reduce our cash use while at the same time have made significant progress to advance our two lead drug candidates, Ryplazim (plasminogen) and PBI-4050. As previously stated, our current business plan calls for a significant reduction in R&D expenditures of up to $30 million in 2019 as compared to this year’s budget. Our primary objective remains to close the gap between the fundamental enterprise value we have built and our current market valuation by strengthening our financial position through the closing of commercial partnerships and equity-related initiatives."

Commenting on the third quarter 2018 financial results, Bruce Pritchard, Prometic’s Chief Operating Officer and Chief Financial Officer, said, "We are ahead of target with the financial guidance provided during the AGM in May 2018 and our last few conference calls. We have effectively implemented cost control measures as evidenced by the trending quarterly decrease in R&D, Administration and Sales & Marketing expenses as well as decreases in net loss and cash flows used in operating activities. Cash used in operations year-to-date was $57 M compared to $95 M for the same period in 2017".

2018 Third Quarter Financial Results

Revenues
Total revenues for the third quarter ended September 30, 2018 were $12.3 million and $36.8 million for the nine months ended September 30, 2018. Revenues from the sale of goods, representing most of the 2018 revenues to date, were $35.3 million during the first nine months ended September 30, 2018 compared to $11 million during the corresponding 2017 period. The $24.3 million increase for 2018 is mainly due to $19.7 million in sales of normal source plasma which occurred in the second and third quarters of 2018 following a change in the production forecast due to the delay of the BLA approval for RyplazimTM (plasminogen). The remainder of the increase of $4.6 million for the nine month period is due to an increase in third party sales in the bioseparation segment. 2018 bioseparation sales are expected to exceed $21 million, which would represent a 30% increase compared to 2017 bioseparation revenues. A comparable level of revenue growth for 2019 is anticipated and is mainly due to the expansion of manufacturing activities by existing clients who utilize Prometic’s products in their production processes, the adoption of products by new clients, the introduction of new products and the continuing expansion of the market for bioseparation products.

Cost of sales and other production expenses
Cost of sales and other production expenses were $9.2 million for the third quarter ended September 30, 2018 compared to $3.8 million for the corresponding period in 2017, representing an increase of $5.5 million. Cost of sales and other production expenses were $30.4 million during the nine months ended September 30, 2018 compared to $7.7 million for the corresponding period in 2017, representing an increase of $22.7 million. The increase was due primarily to the cost of the plasma inventory sold.

Research and Development (R&D)
Total R&D expenses were $24.1 million for the third quarter ended September 30, 2018 compared to $23.3 million for the third quarter ended September 30, 2017. Total R&D expenses were $70.5 million for the nine months ended September 30, 2018 compared to $72.2 million for the corresponding period in 2017, representing a decrease of $1.7 million. The completion of the pivotal phase 3 clinical programs for IVIG and for Ryplazim (plasminogen) and termination of non core preclinical and clinical programs will translate into a significant R&D cost reduction in 2019 compared to 2018.

Administration, Sales & Marketing
Administration, selling and marketing expenses were $6.2 million for the third quarter ended September 30, 2018 compared to $7.7 million for the third quarter ended September 30, 2017. The $1.4 million decrease was due to a reduction in consulting fees and employee compensation expenses. Administration, selling and marketing expenses declined slightly at $20.9 million during the nine months ended September 30, 2018 compared to $22.7 million for the corresponding period in 2017.

Finance Costs
Finance costs were $5.9 million for the third quarter ended September 30, 2018 compared to $2.1 million during the corresponding period of 2017, representing an increase of $3.8 million. Finance costs were $15.5 million for the nine months ended September 30, 2018 compared to $5.3 million during the corresponding period of 2017, representing an increase of $10.2 million. This increase reflects higher debt levels during the nine months ended September 30, 2018 compared to the same period of 2017.

Net Loss
Prometic incurred a net loss of $28.9 million for the third quarter ended September 30, 2018 compared to a net loss of $17.8 million for the third quarter ended September 30, 2017. Prometic incurred a net loss of $96.6 million for the nine months ended September 30, 2018 compared to a net loss of $78.4 million for the corresponding period of 2017. The main reason for the increase in the net loss is that the results for the quarter and the nine months ending September 30, 2017 included $19.7 million in milestone and licensing revenues related to the licensing agreement signed with Jiangsu Renshou Pharmaceutical Co, Ltd.

With the delay of the anticipated launch of its most advanced product, RyplazimTM (plasminogen), the Corporation had to finance its R&D activities via various sources. To date, the Corporation has financed its activities through the sale of products in the bioseparations segment, collaboration arrangements and licensing arrangements, the issuance of debt and equity, operational restructuring as well as investment tax credits. Prometic is currently actively involved in negotiating both equity and equity-linked financing initiatives and continues to be in dialogue with potential licensing partners. Although the Corporation believes that it will be able to obtain the necessary funding as in the past, there can be no assurance of the success of these plans.

"We are inching closer to finalizing our regulatory submission for a new clinical phase 2a study of CA4P combined with the checkpoint inhibitor anti-PD1 in patients with advanced melanoma. I believe that our scientific approach for increasing the anti-tumor immunity of checkpoint inhibitors by inducing ischemic necrosis of tumor cells with CA4P is as good as any of the other checkpoint inhibitor approaches, although it is certainly less well-recognized," stated William D. Schwieterman, M.D., Chief Executive Officer of Mateon Therapeutics. "In addition, we are continuing to screen patients for enrollment into our study of OXi4503 for relapsed/refractory acute myeloid leukemia and myelodysplastic syndromes. Our target is a total of approximately ten patients at the 9.76 mg/m2 dose currently being evaluated."
