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 enrolment on rESPECT to further evaluate efficacy. Alongside a group of international experts, we are now in the process of potentially considering a larger study in light of both our experience with rESPECT to date and the results observed in patients 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, Hôpital 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. Hammel’s 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 community on 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 who are 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."

On January 24, 2022 AIM ImmunoTech Inc. (NYSE: American AIM) ("AIM" or the "Company"), an immuno-pharma company focused on the research and development of therapeutics to treat multiple types of cancers, immune disorders, and viral diseases, including COVID-19, the disease caused by the SARS-CoV-2 virus, reported the publication of positive data from a Phase 1/2 study of intraperitoneal chemo-immunotherapy in advanced recurrent ovarian cancer (Press release, AIM ImmunoTech, JAN 24, 2022, View Source [SID1234606713]). The manuscript titled, "Phase I trial combining chemokine-targeting with loco-regional chemo-immunotherapy for recurrent, platinum-sensitive ovarian cancer shows induction of CXCR3 ligands and markers of type 1 immunity1" was published in the American Association for Cancer Research (AACR) (Free AACR Whitepaper) publication, Clinical Cancer Research.

The Phase 1/2 study being conducted by the University of Pittsburgh School of Medicine is designed to evaluate the immunologic and potential clinical effectiveness of intensive locoregional sequential intraperitoneal (IP) cisplatin (IPC) with intravenous (iv) paclitaxel followed by peritoneal infusion of a chemokine modulatory (CKM) regimen composed of a cocktail of IP rintatolimod and interferon-alpha (IFNα) for patients with advanced stage ovarian cancer (III-IV) at primary neoadjuvant setting. AIM ImmunoTech provided rintatolimod (Ampligen, a dsRNA acting as TLR3 agonist), for the Phase 1/2 study.

"These results represent an important extension of prior studies using human tumor explants that showed Ampligen’s potentially important role as a TLR3 agonist acting synergistically with high-dose IFNα and celecoxib to selectively enhance Teff cell-attractants while suppressing Treg-attractants in the tumor microenvironment with a concomitant increase in the Teff/Treg ratio. This current study shows that similar findings are seen combining Ampligen with chemokine-targeting and chemo-immunotherapy in patients being treated for recurrent ovarian cancer. The importance of boosting the Teff/Treg ratio in the tumor microenvironment is that it is associated with the conversion of ‘cold’ tumors into ‘hot’ tumors, which have an increased sensitivity to chemo-immunotherapy and an improved chance of showing tumor regression. This, of course, creates the potential for a positive survival advantage," stated David Strayer, MD, Chief Medical Officer, Chief Scientific Officer of the Company and Board Certified in Medical Oncology.

1 Clin Cancer Res January 19 2022 DOI: 10.1158/1078-0432.CCR-21-3659

Thomas Equels, Chief Executive Officer of AIM commented, "We are very pleased with these results. Ampligen has demonstrated broad immunological effects and we believe has the potential to be a key component in the treatment of ovarian cancer. We are grateful to the University of Pittsburg School of Medicine and are excited to provide support for a larger Phase 2 study which we believe has the potential to provide hope for patients and their families, as well as drive significant shareholder value."

Twelve patients were enrolled in Phase 1 portion of the trial and were treated with IP cisplatin, IP Ampligen, and oral celecoxib (COX-2 blocker). Patients in cohorts 2, 3 and 4 also received IP IFNα at 2, 6 and 18 million units, respectively. The primary objectives of the study were to evaluate safety, identify Phase 2 recommended dose and characterize changes in the immune TME. Peritoneal resident cells and IP wash fluid were profiled via NanoString and Meso Scale Discovery (MSD) multiplex assay, respectively.

Of the 12 patients enrolled in this Phase 1 trial, 9 (75%) were evaluable for safety, toxicity, and other endpoints. The 3 non-evaluable patients did not complete at least 3 cycles, due to platinum hypersensitivity reactions or port complications. Overall, the regimen was well tolerated, apart from the highest dose of IFNα. Most common toxicities for all grades were anemia (58%), hypomagnesemia (50%), hyponatremia (41.7%), arthralgia (41.7%), and fatigue (41.7%). There was one grade 4 hypomagnesemia (8.3%). Dose limiting toxicities of abdominal pain of grade 3 or more were noted in two patients who received 18MU IFNα (cohort 4).

The Phase 2 recommended dose of IFNα was 6 million units every 3 weeks. Median PFS was 8.4 (3-16.4) months. Median overall survival was 30 (8-66) months. The Company believes these survival outcome data provide an encouraging early signal. Overall response rate was 55.6% and the disease control rate (DCR) was 77.8%, consistent with the expected platinum-sensitive response. Among responders, median duration of response was 11.7 (6-16.4) months.

Key Results Highlights

●Determination of the safety profile and identification of Phase 2 recommended dose for the combination of local cisplatin, Ampligen and IFNα, with oral celecoxib;
●Chemo-immunotherapy combination triggers robust transcriptomic changes in peritoneal resident cells obtained in lonitudinal sampling via IP washes;
●Protein content of IP wash fluid captures treatment-induced increases of IFN-induced immune effector molecules; and
●Tumor immune profile at interval debulking shows partial overlap with IP wash, and points to upregulation of genes encoding for perforin and granzyme B.

Longitudinal sampling of the peritoneal cavity via IP washes demonstrated local upregulation of interferon-stimulated genes, including CTL-attracting chemokines (CXCL-9, -10, -11), MHC I/II, perforin and granzymes. These changes were present two days post chemokine modulation and subsided within one week.

"Epithelial ovarian cancer, the most common form of ovarian cancer, is the most aggressive gynecologic cancer and despite aggressive surgery and chemotherapy treatment options, the 5-year survival rate for patients with advanced high grade serous ovarian cancer remains low. I am very encouraged by the results from this study. With our growing body of positive data, I look forward to further advancing development of this important program with the hope of addressing the significant unmet medical need," added Robert P. Edwards MD, Milton McCall Professor and Chairman, Department of Obstetrics, Gynecology, and Reproductive Sciences, University of Pittsburgh School of Medicine, Director of Women’s Health for UPMC.

Based on these encouraging results, the Company plans on supporting a follow-up Phase 2 trial that will specifically define the immunologic and clinical efficacy of tumor loaded αDC1 vaccine in conjunction with the cisplatin/chemokine modulatory combination regimen will be conducted.

The Phase 2 cohort expansion part of the OBI-999-001 (ClinicalTrials.gov Identifier: NCT04084366) entitled "A Phase 1/2, Open-Label, Dose-Escalation and Cohort-Expansion Study Evaluating the Safety, Pharmacokinetics, and Therapeutic Activity of OBI-999 in Patients with Advanced Solid Tumors" has now begun enrollment. The Phase 2 part of the study will enroll Globo H expressing patients with pancreatic, colorectal and other high Globo H expression solid tumors in more than ten medical centers in the United States and Taiwan.

The Phase 2 cohort expansion part of the OBI-3424-001 (ClinicalTrials.gov Identifier: NCT03592264) entitled "A Phase 1/2 Study of OBI-3424 in Subjects with Advanced Solid Tumors" has also begun enrollment. This study will enroll AKR1C3 expressing patients with pancreatic and other high AKR1C3 expressing solid tumors in select oncology medical centers in the United States.

OBI’s Chairman and Chief Executive Officer, Michael Chang, PhD, noted "OBI Pharma strives to develop novel therapeutics for cancer patients worldwide. Based upon the impressive Phase 1 safety study and preclinical data of OBI-999 and OBI-3424, we are excited to commence our Phase 2 efficacy and safety study in patients with high Globo H or AKR1C3 antigen expression in solid tumors. We would like to thank the commitment of our international investigators to bring these 1st-in-class cancer therapeutic products to potential patients in our ongoing study."

OBI anticipates completing the enrollment of both Phase 2 studies in the second half of 2023.

About OBI-999

OBI-999 is a novel first-in-class Antibody Drug Conjugate (ADC) with a proprietary linker technology that provides a consistent Drug-to-Antibody ratio (DAR) for cancer treatment that is based on Globo H, an antigen expressed in up to 15 epithelial cancers. OBI-999 uses a Globo H antibody to target cancer cells of high Globo H expression. By releasing a small molecule chemotherapeutic drug through the specificity of the antibody, it directly deploys cytotoxic therapy at the targeted cancer cells. In pre-clinical xenograft animal models in multiple tumor types (gastric, pancreatic, lung and breast), OBI-999 has demonstrated profound tumor shrinkage at various doses. In human Phase 1 study, OBI-999 was well-tolerated, and achieved a favorable safety margin which warrants further clinical development. OBI-999 is currently in a Phase 2 clinical trial (ClinicalTrials.gov Identifier: NCT04084366) in medical centers in the US and Taiwan. OBI Pharma owns global rights to OBI-999.

About OBI-3424

OBI-3424 is a first-in-class novel small-molecule prodrug that selectively targets cancers overexpressing the enzyme aldo-keto reductase 1C3 (AKR1C3), and selectively releases a potent DNA alkylating agent in the presence of the AKR1C3 enzyme. This selective mode of activation distinguishes OBI-3424 from traditional alkylating agents, such as cyclophosphamide and ifosfamide, which are non-selective.

AKR1C3 overexpression has been documented in a number of treatment-resistant and difficult-to-treat cancers including hepatocellular carcinomas (HCC), castrate-resistant prostate cancer (CRPC), and T-cell acute lymphoblastic leukemia (T-ALL). AKR1C3 is highly expressed in up to 15 solid and liquid tumors.

Furthermore, individualized patient selection by staining for AKR1C3 overexpression by immunohistochemistry can be performed based on tumor biopsies or circulating tumor cells to identify patients with other tumor types most likely to respond to treatment with OBI-3424, and thus offering the possibility for a streamlined clinical development strategy.

OBI-3424 is currently in a Phase 2 trial (ClinicalTrials.gov Identifier: NCT03592264) in medical centers in the US. OBI owns global rights to OBI-3424 except the Asia Pacific region.
