LYON, France and CAMBRIDGE, Mass., Nov. 05, 2020 (GLOBE NEWSWIRE) — ERYTECH Pharma (Nasdaq & Euronext: ERYP), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, today provided a business and financial update.

“The third quarter was marked by continued momentum and strong execution across our late-stage clinical programs despite the ongoing COVID-19 global pandemic,” said Gil Beyen, CEO of ERYTECH Pharma. “TRYbeCA-1, our Phase 3 trial in 2L pancreatic cancer, has nearly completed enrollment and the NOPHO-sponsored Phase 2 trial in acute lymphoblastic leukemia (ALL) achieved full enrollment in August. As we look towards the balance of the year and into 2021, we are keenly focused on continued milestone execution in all of our clinical programs, but specifically the interim and final readouts in TRYbeCA-1 and the final data in the NOPHO Phase 2 clinical trial. If both are favorable, we would have the opportunity to prepare and submit applications for marketing approval in two indications of high unmet need. I am also pleased to report that we have secured financing alternatives despite the turbulent market conditions. Collectively, the recently secured state-guaranteed loan, the closing of a convertible debt financing, and the establishment of an ATM equity facility, give us the opportunity to extend our cash horizon until the end of next year.”

Business Highlights

• TRYbeCA-1, the pivotal Phase 3 clinical trial evaluating ERYTECH’s lead product candidate, eryaspase, in second-line metastatic pancreatic cancer, is nearing complete enrollment and the required number of events to trigger the interim superiority analysis has been reached. The Independent Data Monitoring Committee (IDMC) is expected to conduct the interim analysis in the first quarter of 2021. Since the interim analysis does not include a test for futility, there will be two possible outcomes: the trial will either (1) continue toward a final analysis, expected in the second half of 2021, or (2) conclude early for superiority if compelling improvement of overall survival is demonstrated. TRYbeCA-1 is being conducted in close to 90 clinical sites in the United States and 11 countries across Europe, and targets to enroll approximately 500 patients. Eligible patients are randomized 1-to-1 to receive eryaspase in combination with standard chemotherapy (gemcitabine/nab paclitaxel or an irinotecan based regimen) or chemotherapy alone. The primary endpoint of TRYbeCA-1 is overall survival (OS). The trial is designed to identify an OS hazard ratio (HR) of 0.725 with close to 90% power.
• The Phase 2 clinical trial of eryaspase in acute lymphoblastic leukemia (ALL) patients who developed hypersensitivity to pegylated asparaginase, sponsored by the Nordic Organization of Pediatric Hematology and Oncology (NOPHO), completed enrollment in August 2020. Fifty-five patients have been enrolled at 22 clinical sites in the Nordic and Baltic countries of Europe. Preliminary findings of the trial suggest that eryaspase achieved the target level and duration of asparaginase activity in these patients. The addition of eryaspase to the combination chemotherapy was associated with an acceptable tolerability profile, enabling the majority of these patients to receive their fully intended courses of asparginase. Hypersensitivity to pegylated asparaginase represents an important unmet medical need, given the limited treatment choices for these patients. The abstract with interim data from the NOPHO trial has been selected for oral presentation at the ASH Annual Meeting in December 2020. Top-line final results will be presented at that occasion. ERYTECH plans to further discuss these data with the FDA to determine the potential next steps and to assess the path forward to potential approval for eryaspase in this indication.
• ERYTECH strengthened its leadership team with the appointment of Dr. Stewart Craig as its Chief Technical Officer (CTO) and member of the executive team. Dr. Craig brings 35+ years of experience in the development, manufacture, technical operations, quality systems and regulatory affairs for complex biologics and cell & gene therapies worldwide for companies such as Orchard Therapeutics, Sangamo and Stem Cells Inc.

Financial Results for the first nine months of 2020

• Key financial figures for the first nine months of 2020 compared with the same period of the previous year are summarized below:

• Net loss for the first nine months of 2020 was €53.6 million, up €10.3 million (+24%) year-over-year, with a €4.7 million increase (+10%) in operating loss and a €5.6 million decrease in financial income. The €4.7 million increase in operating loss was attributable to a €6.0 million increase in preclinical and clinical development expenses, mostly related to expenses for the Company’s Phase 3 clinical trial in pancreatic cancer, a €2.3 million decrease in general and administrative expenses, which was related to the end of expenses related to the establishment of the manufacturing capacity, mostly incurred in 2019, and a €1.0 million decrease in income, of which €0.9 million consisted in the upfront payment from the June 2019 license agreement with SQZ Biotechnologies that did not recur in 2020.

• As of September 30, 2020, ERYTECH had cash and cash equivalents totaling €40.5 million (approximately $47.5 million), compared with €73.2 million on December 31, 2019 and €45.4 million on June 30, 2020. The €32.7 million decrease in cash position during the first nine months of 2020, consisting of €14.6 million in the first quarter of 2020, €13.1 million in the second quarter and €4.9 million in the third quarter, was the result of a €32.3 million net cash utilization which was mostly comprised of a €38.2 million net cash utilization in operating activities, €1.4 million used for investing activities and €7.4 million generated in financing activities, while the depreciation at the end of the period of the U.S. dollar against the euro led to a €0.4 million negative currency exchange impact.
• Financing activities included the draw down of two tranches of €3 million each, in July and August 2020, under the convertible bond financing agreement with Alpha Blue Ocean, for net proceeds of €5.6 million. As of the date of this press release, all notes have been converted and have resulted in the issuance of 1,125,873 new shares, representing 5.90% of the Company’s outstanding share capital to date.
• In September, ERYTECH announced the implementation of an at-the-market (ATM) equity financing program. A new shelf registration statement on Form F-3 was filed by the Company with the U.S. Securities and Exchange Commission (the “SEC”) on September 21, 2020 to roll over the Company’s previously filed shelf registration and to cover the ATM program and the registration statement was declared effective by the SEC on October 9, 2020. To date, the Company has not sold any securities pursuant to the ATM program.
• Earlier this week, ERYTECH announced that it had secured with Bpifrance and Société Générale a €10 million non-dilutive financing in the form of a state-guaranteed loan (PGE loan). Each of Bpifrance and Société Générale will provide ERYTECH with a loan in the amount of €5 million and the French government will guarantee 90% of the total amounts due under the loans. The loans will bear interest at a fixed rate of 1.75% and 0.25% per annum respectively, with an initial term of one year. At the end of this initial term, the Company, at its option, may defer repayment of the principal amount over a five-year period.
• The Company believes that the €10 million state-guaranteed loan, in combination with its current cash and cash equivalents, will extend its cash horizon into Q3 2021. When taking into account the potential proceeds under the convertible bonds financing and the ATM program, the horizon could be extended until the end of 2021.

Key News Flow and Milestones Expected Over the Next 12 Months

• Topline final results of the Phase 2 investigator-sponsored NOPHO trial in acute lymphoblastic leukemia at ASH (Dec 2020)
• Interim (superiority) analysis in the TRYbeCA-1 Phase 3 clinical trial in 2L metastatic pancreatic cancer (Q1 2021)
• First patient enrolled in the Phase 1 investigator-sponsored trial in 1L metastatic pancreatic cancer (Q4 2020); interim updates and results expected in 2021
• Final results of TRYbeCA-1 trial (in case the IDMC recommends to continue the trial as planned at the interim superiority analysis) (Q4 2021)
