Cambridge, MA (U.S.) and Lyon (France), January 24, 2021 ERYTECH Pharma (Nasdaq & Euronext: ERYP),a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, todayannouncedthe presentation of results of two trials evaluating eryaspasein advanced pancreatic cancerat the American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO GI) on January 21, 2022.
Abstract # 581 - rESPECT A Phase I dose-escalation study of eryaspase in combination with modified FOLFIRINOX in locally advanced and metastatic pancreatic ductal adenocarcinoma: Interim update (NCT04292743).
Dr Marcus Noel, MD, medical oncologist at Georgetown University Lombardi Comprehensive Cancer Center, Washington, DC, USA, and principal investigator of the rESPECT trial, presented an interim update of this Phase 1 trial evaluating eryaspase in combination with mFOLFIRINOX, a fluoropyrimidine- and irinotecan-based chemotherapy regimen, as first-line treatment for advanced pancreatic cancer.
To date, eleven patients have been enrolled with a mean age of 68. Three patients were enrolled at a dose level of 75 U/kg and eight at a dose level of 100 U/kg. The novel combination of mFOLFIRINOX plus eryaspase was well tolerated and no dose limiting toxicity (DLT) was observed. The maximum tolerated dose (MTD) has been declared with 5-FU 2400 mg/m2, Oxaliplatin 85 mg/m2, Irinotecan 150 mg/m2 and eryaspase 100 units/kg.
Among ten patients with imaging available to evaluate response, 5 (50%) had partial response (PR) and 5 (50%) had stable disease (SD), corresponding to a disease control rate (PR + SD) of 100%. One patient with locally advanced disease became eligible for resection after receiving therapy.
Dr Marcus Noel, MD, Principal Investigator of the rESPECT IST, commented:The early results from the rESPECT study are highly encouraging for the combination of eryaspase and modified FOLFIRINOX in first-line pancreatic cancer, with the MTD now established and initial signs of clinical activity demonstrated. We plan to expand enrolmenton rESPECT to further evaluate efficacy. Alongside a group of international experts, we are now in the process of potentially considering a larger studyin light of both our experience with rESPECT to date and the results observed inpatients treated with the combination of eryaspase and FOLFIRI in TRYbeCA-1.
Abstract # 518 - TRYbeCA-1 A randomized, Phase 3 study of eryaspase in combination with chemotherapy versus chemotherapy alone as second-line treatment in patients with advanced pancreatic adenocarcinoma (NCT03665441).
Prof. Pascal Hammel, MD, PhD, medical oncologist at University Paris-Saclay, Hpital Paul Brousse (APHP), France, and co-principal investigator of the TRYbeCA-1 trial, presented the final results of this Phase 3 trial. The top-line results had been reported in October 2021.
As reported before, the trial did not meet primary efficacy endpoint of overall survival (OS). The median OS for patients treated with eryaspase plus chemotherapy was 7.5 months (95% CI, 6.5-8.3), compared to 6.7 months (95% CI, 5.4-7.5) for chemotherapy alone.
The prespecified subgroup of patients treated with eryaspase and FOLFIRI, a fluoropyrimidine- and irinotecan-based chemotherapy regimen, demonstrated a nominal increase in median OS of 2.3 months versus FOLFIRI alone, from 5.7 to 8 months (HR = 0.81; 95% CI, 0.6-1.1). The FOLFIRI treated patients represented approximately 42% of the patients in this trial.
The treatment was well tolerated, and the addition of eryaspase did not enhance the cytotoxicity of chemotherapy.
Following Prof. Hammels presentation, the discussant, Dr Nilofer Saba Azad, MD, Department of Oncology, Johns Hopkins Sidney Kimmel Cancer Center, concluded that TRYbeCA-1 was well designed with appropriate power and stratification factors. Furthermore, the study findings open the possibility for additional study of eryaspase in combination with FOLFIRI in neo-adjuvant, adjuvant and first-line settings.
While it was initially disappointing to be unable to demonstrate an improvement in survival across the entire population in one of the largest prospective second-line pancreatic cancer studies conducted to date, TRYbeCA-1 has improved our understanding of pancreatic cancer in this setting, and importantly, has also identified a potential utility of the combination of eryaspase with fluoropyrimide- and irinotecan-containing regimens in this difficult to treat cancer. I look forward to furthering discussions with the pancreatic cancer communityon future potential clinical trials with eryaspase, said Prof. Pascal Hammel, MD, PhD, Co-principal Investigator of the TRYbeCA-1 trial.
Dr Iman El-Hariry, MD, PhD, Chief Medical Officer at ERYTECH, added:I would like to thank all investigators and patients whoare participating and have participated in the rESPECT and the TRYbeCA-1 studies. Pancreatic cancer remains very difficult to treat with few treatment options, but we have been encouraged by the clinical activity observed with eryaspase in both trials. We continue to evaluate the path forward for potential further clinical development focused on evaluating eryaspase in combination with fluoropyrimidine-and irinotecan-based chemotherapy. Meanwhile, the company is currently preparing a BLA to seek approval for eryaspase for the treatment of ALL patients who developed hypersensitivity to E. coli-derived asparaginase, based on the results of a Phase 2 clinical trial sponsored by the NOPHO group1. The Company intends to submit the BLA in the first quarter of 2022, subject to completion of remaining data requested by the FDA.
About ERYTECH and eryaspase (GRASPA)
ERYTECH is a clinical-stage biopharmaceutical company developing innovative red blood cell-based therapeutics for severe forms of cancer and orphan diseases. Leveraging its proprietary ERYCAPS platform, which uses a novel technology to encapsulate drug substances inside red blood cells, ERYTECH is developing a pipeline of product candidates for patients with high unmet medical needs. ERYTECHs primary focus is on the development of product candidates that target the altered metabolism of cancer cells by depriving them of amino acids necessary for their growth and survival.
The Companys lead product candidate, eryaspase (GRASPA), which consists of L-asparaginase encapsulated inside donor-derived red blood cells, targets the cancer cells altered asparagine and glutamine metabolism. The proof of concept of eryaspase as a cancer metabolism agent was established in different trials in acute lymphoblastic leukemia (ALL) and pancreatic cancer. An investigator sponsored Phase 2 trial (IST) evaluating the use of GRASPA in ALL patients who developed hypersensitivity reactions to pegylated asparaginase recently reported positive results, based on which the Company intends to request approval in the United States and potentially other territories. The Company is also pursuing a Phase 1 investigator-sponsored clinical trial in first-line pancreatic cancer.
Eryaspase received Fast Track designation from the U.S. Food and Drug Administration (FDA) for the treatment of advanced pancreatic cancer and treatment of acute lymphoblastic leukemia (ALL) patients who have developed hypersensitivity reactions to E. coli-derived pegylated asparaginase. The FDA and the European Medicines Agency have granted eryaspase orphan drug status for the treatment of pancreatic cancer and ALL.
ERYTECH produces its product candidates for treatment of patients in Europe at its GMP-approved manufacturing site in Lyon, France, and for patients in the United States at its GMP manufacturing site in Princeton, New Jersey, USA. Eryaspase is not an approved medicine.
ERYTECH is listed on the Nasdaq Global Select Market in the United States (ticker: ERYP) and on the Euronext regulated market in Paris (ISIN code: FR0011471135, ticker: ERYP). ERYTECH is part of the CAC Healthcare, CAC Pharma & Bio, CAC Mid & Small, CAC All Tradable, EnterNext PEA-PME 150 and Next Biotech indexes.
