ROCKVILLE, Md.--(BUSINESS WIRE)--Nov. 9, 2022-- GlycoMimetics, Inc. (Nasdaq: GLYC), a late clinical-stage biotechnology company discovering and developing glycobiology-based therapies for cancers and inflammatory diseases, today reported its financial results and highlights for the third quarter ended September 30, 2022. Cash and cash equivalents as of September 30, 2022, were $51.6 million.

“Blinded pooled survival data in our pivotal Phase 3 study show patients living longer than what would be expected based on publicly available historical data. We approached the FDA as we felt an ethical obligation to conduct an interim analysis and have the independent DMC assess whether the prolonged survival observed is linked to treatment with uproleselan,” said Harout Semerjian, Chief Executive Officer. “We are pleased the FDA is aligned with our position. Whether the DMC recommends that we continue the study as originally planned or immediately unblind for full analysis, we remain confident and excited in the potential of uproleselan to improve outcomes in relapsed/refractory AML.”

The statistical plan cleared with FDA is for the independent DMC to review efficacy and safety data at around 80% of planned survival events. The company has initiated the required regulatory and Institutional Review Board (IRB) approvals to amend the protocol to conduct the interim utility analysis and share the data with the DMC by end of Q1 2023. The DMC is then expected to meet to review the data and recommend whether the study should continue as planned or should be immediately unblinded for full analysis, which could occur if the efficacy data from treatment with uproleselan in combination with standard chemotherapy is observed to be compelling.

As part of its ongoing monitoring of blinded pooled survival data within the Phase 3 pivotal study, the company is now projecting the final survival events trigger to occur around year-end 2023. This change in timeline is the result of patients continuing to live longer than observed in historical benchmarks used to design the study and was the primary rationale for the company to approach the FDA regarding conduct of an interim utility analysis.

The company’s cash runway now extends to year-end 2023 as a result of the decrease in expenses from the transition of the Phase 3 relapsed/refractory AML clinical trial to follow-up, the completion of key uproleselan commercial manufacturing activities, and the realization of savings from a headcount reduction earlier this year. The company’s allocation of its capital resources will continue to prioritize the advancement of the uproleselan development program, including key regulatory and pre-commercial activities.

The pivotal Phase 3 trial evaluating uproleselan in addition to a standard chemotherapy regimen in patients with relapsed/refractory AML completed enrollment in November of 2021. A total of 388 patients across 70 sites in nine countries were randomized in the clinical trial, which has a primary endpoint of overall survival.

Operational Highlights

• Following alignment with the FDA on conducting an interim analysis, GlycoMimetics initiated the required regulatory and IRB approvals to update the protocol of the company’s pivotal Phase 3 study of uproleselan in relapsed/refractory AML. These efforts are ongoing and are expected to be completed in Q1 2023.
• Initial clinical data from two investigator-sponsored trials studying the use of uproleselan in combination with other treatments in patients with different forms of AML have been accepted for poster presentation at the 64th American Society of Hematology (ASH) Annual Meeting (ASH Press Release). These studies examine the safety and potential efficacy of uproleselan to benefit patients across the AML spectrum, including older, unfit treatment naïve patients and those with treated secondary AML.
• The National Cancer Institute (NCI) continues to prepare for its planned interim analysis of event-free survival of the 267 patients in its Phase 2/3 clinical trial evaluating uproleselan in newly diagnosed older adults with AML who are fit for chemotherapy. When available, the company intends to share the outcome of the NCI’s interim analysis of the Phase 2 data and whether the trial will reopen for Phase 3 recruitment. The NCI will determine the timing and medical meeting to present the full results of the Phase 2 study.

Third Quarter 2022 Financial Results:

Cash position: As of September 30, 2022, GlycoMimetics had cash and cash equivalents of $51.6 million as compared to $90.3 million as of December 31, 2021.

Revenue: There was no revenue recognized during the three months ended September 30, 2022, compared to $87,000 of revenue recognized during the three months ended September 30, 2021.

R&D Expenses: Research and development expenses decreased to $4.9 million for the quarter ended September 30, 2022, as compared to $13.3 million for the same period in 2021. The significant decrease in expenses was primarily due to lower clinical trial and development costs related to the pivotal Phase 3 clinical trial of uproleselan in individuals with relapsed/refractory AML as patient enrollment ended in November 2021.

G&A Expenses: General and administrative expenses decreased to $3.8 million for the quarter ended September 30, 2022, as compared to $4.1 million for the third quarter of 2021 primarily due to lower professional fees.

Shares Outstanding: Shares of common stock outstanding as of September 30, 2022, were 52,423,944.

The company will host a conference call and webcast today at 8:30 a.m. ET. To access the call by phone, please go to this registration link and you will be provided with dial in details. Participants are encouraged to connect 15 minutes in advance of the scheduled start time.

About Uproleselan

Discovered and developed by GlycoMimetics, uproleselan is an investigational first-in-class, E-selectin antagonist. Uproleselan (yoo’ pro le’se lan), currently in a comprehensive Phase 3 development program in acute myeloid leukemia (AML), has received Breakthrough Therapy designation from the U.S. FDA and from the Chinese National Medical Products Administration for the treatment of adult AML patients with relapsed or refractory disease. Uproleselan is designed to block E-selectin binding and stimulation of myeloid cells. E-selectin is expressed on the surface of blood vessels, and its binding to myeloid cells confers a pro-survival effect via NF-kB signaling. Uproleselan is designed to provide a novel approach to disrupting established mechanisms of leukemic cell resistance.
