"After completing a Phase 3 trial of lenzilumab, in 2021, for the treatment of patients hospitalized with COVID-19 pneumonia, we look forward to advancing our efforts to develop lenzilumab as a complementary therapy to potentially reduce CAR-T associated toxicities and to potentially improve outcomes for non-Hodgkin lymphoma patients," said Adrian Kilcoyne, Chief Medical Officer, Humanigen. "My experience working in the development of CAR-T therapies, which are now currently commercially available, suggests preventing toxicity and optimizing durable response rates remain challenges. Our plans include initiating the Phase 3 SHIELD study of lenzilumab in the first half of 2022 and we may be able to announce interim data at ASH (Free ASH Whitepaper) 2022."

Abstract #2777

Optimized Inhibition of GM-CSF in Preclinical Models of Anti-CD19 Chimeric Antigen Receptor T Cell Therapy

Summary: The abstract describes the evaluation of differential targeting of the GM-CSF ligand using lenzilumab compared to targeting the GM-CSFα receptor using a different antibody in pre-clinical models. The research demonstrated significant differences on CAR-T cell functions and CAR-T cell-monocyte interactions when GM-CSF is neutralized with lenzilumab compared to blocking its receptor with other agents. A key finding is that lenzilumab neutralization of GM-CSF improved CAR-T cell proliferation, but the GM-CSFRα receptor blocking antibody may significantly inhibit CAR-T cell proliferation in a dose-dependent manner. This may have efficacy implications.

Reven reported the publication of a peer-reviewed article in the prestigious medical journal Frontiers in Oncology. The article reports a systematic analysis of the antibody responses to COVID-19 vaccination in cancer patients. This analysis was completed in collaboration with the Hacettepe University Cancer Institute team in Ankara/Turkey and Ares Pharmaceuticals, LLC in St. Paul, MN. COVID-19 vaccine seroconversion rates (i.e., antibody development success) were substantially lower in patients with hematologic malignancies (example: leukemias and lymphomas) and cancer patients receiving chemotherapy or immunosuppressive treatments than controls who did not have cancer.

The article, "Antibody Responses to COVID-19 Vaccination in Cancer: A Systematic Review," has been published in Frontiers in Oncology, and it is available online.

The corresponding author, Executive Vice-President for Global Medical Affairs and Chief Medical Officer of Reven, Dr. Fatih Uckun MD PhD, explained: "We are reporting the challenges for oncology patients in achieving adaptive immunity against COVID-19. This report illustrates the importance of developing effective treatments against high-risk COVID-19 and COVID-19-associated cytokine release syndrome (CRS) considering the poor performance of vaccinations in cancer patients. Reven’s clinical development efforts for our lead COVID-19 drug candidate RJX are aimed at reducing the risk of life-threatening complications of COVID-19 and accelerating the full recovery of high-risk patients, such as those with cancer."

"This paper illustrates the importance of our randomized trial to address unmet needs in COVID-19 therapy," added Peter Lange, the CEO of Reven.

Reven had recently announced the successful completion of Part 1 of the Two-Part, Two Cohort Multi-Center Phase I/II trial of RJX in hospitalized high-risk COVID-19 patients. 12 hospitalized adult patients with symptomatic high-risk COVID-19 pneumonia and abnormally elevated inflammation markers in the blood were treated with daily intravenous infusions of RJX in combination with standard of care. Nine (9) of the 12 patients, including 3 patients with hypoxemic respiratory failure, had shown rapid clinical recovery with normalization of the abnormally elevated inflammation markers in the blood and were discharged from hospital at a median of 5 days. All patients tolerated their RJX infusions without any side effects. An Independent Data and Safety Monitoring Board (DSMB) that oversees and acts independently from the Reven project team had reviewed the clinical data in all 12 patients, and approved the initiation of the randomized, double-blind Part 2 portion of the Phase 2 study.

10 patients have already been enrolled and dosed in the randomized, double-blind, placebo-controlled Part 2 portion of the Phase 2 study (ClinicalTrials.gov Identifier: NCT04708340; View Source). This FDA-approved controlled clinical trial is aimed at evaluating the efficacy and safety of RJX in side-by-side comparison with a placebo as an adjunct to standard of care in hospitalized COVID-19 patients. Michael Volk, Director and Chief Strategy Officer of Reven, stated, "We are excited about the rapid progress in our clinical program against COVID-19."

"We are expecting topline data from this very important study by end of 2021," said Brian Denomme, Reven’s President.

"We are diligently advancing the clinical development of RJX," said Fatih Uckun, MD PhD.

RJX is an intravenous (IV) formulation of a patented first-in-class pharmaceutical composition containing a specific mixture of antioxidant and anti-inflammatory ingredients that is being developed for more effective treatment of patients with inflammatory disorders, including COVID-19 patients with viral sepsis, multi-system inflammation, cytokine release syndrome (CRS), shock, ARDS, and multi-organ failure. The FDA-approved clinical trial is aimed at evaluating the efficacy and safety of RJX as an adjunct to standard of care in hospitalized COVID-19 patients, who have high-risk features for progression to severe disease and ARDS and patients with hypoxemic respiratory failure receiving either non-invasive positive pressure ventilation (NIPPV) or high flow oxygen, who have not yet developed ARDS to require mechanical ventilation. Since RJX is a potent anti-oxidant and anti-inflammatory agent that has been shown to reduce the tissue-level oxidative stress in multiple organs in animal models of severe systemic inflammation, shock, cytokine storm, and multiorgan failure, Reven hopes that it will contribute to prevention of progression of COVID-19 and its faster resolution in high-risk patients.

Bluestar Genomics’ pancreatic cancer test uses a standard blood draw to assess whether an individual has an abnormal DNA signal associated with pancreatic cancer. This one-of-its-kind test would allow for early diagnosis of pancreatic cancer, one of the deadliest cancers in part because there are no existing screening methods to enable early detection. When found early, accurate detection of pancreatic cancer enables more timely, potentially curative surgical and therapeutic options for patients. People with new-onset diabetes are at high-risk of pancreatic cancer. Out of an estimated 60,000 patients diagnosed each year with pancreatic cancer in the U.S. alone, nearly 25% are found to have new-onset diabetes before a pancreatic cancer diagnosis.

"Along with our test’s recent designation by the FDA as a breakthrough device, the findings from this study presented at APA underscore the opportunity we have to make a positive difference for patients by bringing this pancreatic cancer test to market," said Samuel Levy, Ph.D., chief executive and chief scientific officer at Bluestar Genomics and lead author of the study. "Based on these results, we are moving forward with completing the analytical validation in the coming months and making a CLIA laboratory developed test available next year."

Unlike other liquid biopsy cancer tests, this pancreatic cancer-focused test is performed with Bluestar Genomics’ groundbreaking epigenomics technology platform that uses state-of-the-art machine learning coupled with a DNA-based 5-hydroxymethylcytosine (5hmC) biomarker as a precise screening method for detecting cancer at earlier stages. By combining a novel 5-hydroxymethylation enrichment assay with high-throughput sequencing, it is possible to generate powerful predictive models using machine learning to enable the detection of pancreatic cancer in patients with high accuracy.

Pancreatic cancer is the third-leading cause of cancer death in the U.S., surpassing common cancers such as breast and prostate. Bluestar Genomics’ test has the potential to screen an estimated one million adults diagnosed annually with new-onset diabetes in the U.S. for the early detection and treatment of pancreatic cancer, which could enable better patient outcomes.

The study presented at APA included 917 patients, examining whole blood samples from 117 patients with pancreatic cancer and 800 non-cancer control patients, with and without new-onset diabetes. The predictive model was trained on samples using 5hmC signals from cell-free DNA. When applied to the validation set, 50% of which were early stage (stages I and II) disease, this model showed a median of 51.5% sensitivity and 98% specificity. Results from the study demonstrated pancreatic cancer signal detection in plasma-derived cell-free DNA using 5hmC profiles. Overall, these findings showed that the model performed consistently well between the training and independent validation datasets.

In addition to completing the analytical validation, Bluestar Genomics is planning a large clinical study to further validate the use of this test to detect pancreatic cancer in patients with new-onset diabetes.

With the commercialization efforts for the test focused on pancreatic cancer as well as a growing pipeline of other epigenomic assays, the company also announced that Jim Vaughn, R. Ph., has joined the company as its chief commercial officer. Vaughn brings more than 20 years of strategic leadership experience in commercializing molecular tests in oncology, including a breadth of expertise in sales, marketing, and reimbursement strategy. Most recently, Vaughn led efforts to successfully commercialize the Oncotype DX portfolio at Genomic Health/Exact Sciences, where he was the global chief commercial officer.

"Liquid biopsy continues to show great promise in improving cancer patient survival," said Vaughn. "Our epigenomics approach is to focus on the highest-risk cancers with the greatest needs, starting with pancreatic and certain women’s cancers. I look forward to leading our efforts to bring new-generation liquid biopsy tests to physicians and patients to enable curative therapies."

"The positive data at APA along with Jim’s appointment as CCO provide confidence for the company to move forward with commercial planning for our first product, with the goal of developing a pipeline of tests employing our unique type of epigenomics analysis," said Levy.

"Syros made significant progress this quarter as we executed on important milestones across our portfolios in targeted hematology and CDK inhibition as well as strengthened our leadership team with the additions of Conley Chee as Chief Commercial Officer and Jason Haas as Chief Financial Officer," said Nancy Simonian, M.D., Chief Executive Officer of Syros. "In September, we dosed the first patient in our SELECT-AML-1 Phase 2 trial of tamibarotene, as well as in our dose confirmation study of SY-2101 in APL. Taken together, these accomplishments mark important progress toward potentially offering new standards of care for people living with hematologic cancers and showcase our commitment to building a robust and synergistic portfolio in targeted hematology."

Dr. Simonian continued, "Building on our leadership in selective CDK7 inhibition, we presented encouraging clinical data from our Phase 1 trial of SY-5609. The data demonstrated proof-of-activity across multiple difficult-to-treat tumors and suggest that we have identified an optimal dosing schedule for further development. Based on these results, we plan to evaluate SY-5609 as part of a three-pronged combination strategy in areas of high unmet need that are supported by strong mechanistic rationale and clinical or pre-clinical activity. We expect to initiate an expansion cohort in pancreatic cancer as well as a Phase 1b trial in mantle cell lymphoma in the fourth quarter of 2021 and the first half of 2022, respectively, and look forward to working with Roche to evaluate SY-5609 in combination with its PDL1 inhibitor in BRAF-mutant colorectal cancer."

Also in September, Syros dosed the first patient in its SELECT-AML-1 Phase 2 trial to evaluate the safety and efficacy of tamibarotene in combination with venetoclax and azacitidine. Following a safety lead-in, approximately 80 patients will be randomized 1:1 to receive tamibarotene in combination with venetoclax and azacitidine, or venetoclax and azacitidine alone. The primary endpoint is composite complete response rate.
At the 2021 ESMO (Free ESMO Whitepaper) Congress in September, Syros presented new data from its Phase 1 trial of SY-5609 in heavily pretreated patients with select-solid tumors, which demonstrated clinical activity at tolerable doses as a single agent across multiple tumor types:
Thirteen patients achieved stable disease (SD) with tumor regressions of up to 20% in six of those patients, across multiple tumor types.
The most substantial clinical activity was observed in heavily pre-treated patients with advanced pancreatic cancer. Five of 13 of these evaluable patients achieved SD, with tumor reductions in two of those patients.
Across all doses and schedules, the majority of adverse events were low-grade and reversible.
Optimal dosing regimen of 7 days on/7 days off was identified for further evaluation.
Based on these data along with pre-clinical data, strong mechanistic rationale, and high unmet need, Syros is evaluating SY-5609 in a three-pronged combination approach:
Combination with chemotherapy for the treatment of pancreatic cancer.
Combination with a BTK inhibitor for the treatment of mantle cell lymphoma.
Combination with PDL1 inhibitor for the treatment of BRAF-mutant colorectal cancer. As previously disclosed, Syros entered into an agreement with Roche to explore this combination in Roche’s Phase 1/1b INTRINSIC trial.
RECENT CORPORATE HIGHLIGHTS

In October, Syros appointed Jason Haas as Chief Financial Officer. Jason brings more than 25 years of healthcare investment banking and corporate finance experience.
In September, Syros appointed Conley Chee as the Company’s first Chief Commercial Officer. Conley brings 20 years of pharmaceutical sales leadership, marketing, and strategy experience.
Also in September, Syros appointed Deborah Dunsire, M.D., a highly respected industry veteran, to the Board of Directors.
