ROCKVILLE, Md.--(BUSINESS WIRE)--GlycoMimetics, Inc. (Nasdaq: GLYC) today reported its financial results for the fourth quarter and year ended December 31, 2020, and highlighted recent Company events, including several accomplishments reported to date in 2021. Cash and cash equivalents at December 31, 2020 were $137.0 million.

“During 2020, we remained on track to complete enrollment of our uproleselan pivotal trial in the second half of 2021. Uproleselan continues to have strong support from collaborators working with us in the clinical and preclinical arenas. We believe this broad-based support for uproleselan reflects confidence in our approach to establish this product candidate as a potential foundational therapy across the spectrum of AML. In addition, the Chinese regulatory authority granted Breakthrough Therapy designation for uproleselan for the treatment of relapsed/refractory AML, complementing a prior designation by the FDA. We will seek to demonstrate in both ongoing and new clinical trials that uproleselan in combination with standard treatments may both extend survival and ameliorate the severe side effects experienced by cancer patients,” commented Rachel King, Chief Executive Officer.

“December’s ASH meeting gave us an opportunity to share an in-depth understanding of the rivipansel Phase 3 and subsequent Open Label Extension (OLE) data demonstrating the key role of E-selectin and importance of early treatment in VOC. Nevertheless, based on input from the FDA with respect to rivipansel as well as input from key opinion leaders in sickle cell disease, we intend to focus development in this setting on our GMI-1687 product candidate,” she added. “We believe that development of GMI-1687 will be a better option than additional clinical work on rivipansel. This is particularly important since the care of individuals with sickle cell disease has continued to shift to the outpatient setting, a trend which has accelerated during the pandemic. As a potentially subcutaneously available compound, GMI-1687 may be ideally suited to this changing landscape, and we have, therefore, initiated IND-enabling work with the compound. Our current cash position provides a runway into the fourth quarter of 2022 and through several key milestones in the uproleselan program, based on our current plan.”

Operational Highlights

Uproleselan

• GlycoMimetics’ pivotal Phase 3 trial in relapsed/refractory AML continued to enroll patients in the U.S., Australia and in Europe at a steady pace in the fourth quarter of 2020. With momentum carrying into 2021 and building further with newly added sites, the Company reiterates its projection that enrollment will be completed in the second half of 2021.
• In parallel, the NCI-sponsored Phase 3 clinical trial, which is designed to evaluate uproleselan in newly diagnosed older adults with AML who are fit for chemotherapy, has continued to enroll patients. Based on the NCI’s public disclosures, the Company anticipates the trial will achieve enrollment of the initial 262 patients necessary for the interim event-free survival assessment before the 2021 year-end.
• Apollomics, our exclusive collaborator for development and commercialization of uproleselan in Greater China, received Breakthrough Therapy designation from the China National Medical Products Administration (NMPA) in early 2021.
• Uproleselan was featured in December 2020 at the Annual Meeting of the American Society of Hematology (ASH), in a presentation by the MD Anderson Cancer Center Department of Leukemia. Specifically, new preclinical data were presented elucidating how inhibiting E-selectin with uproleselan overcomes microenvironment-mediated resistance to venetoclax/HMA therapy, resulting in prolonged survival. We are now working actively toward exploring this combination through an investigator-sponsored clinical trial.

GMI-1687

• At the Annual Scientific Conference on Sickle Cell and Thalassemia (ASCAT) meeting in October and at the ASH meeting in December, GlycoMimetics gave oral presentations on the effects of GMI-1687 in two separate preclinical models of VOC. These presentations highlighted the drug candidate’s ability to prevent sickle red blood cell adherence to inflamed vasculature, inhibit vessel occlusion and restore normal blood flow within 90 minutes of administration. Suitable for subcutaneous dosing, the data support the development of GMI-1687 as a fast-acting, E-selectin inhibitor that could potentially be self-administered at the time of VOC onset to obviate the need for opioids, acute care visits and inpatient hospitalization.
• In 2020, the Company initiated an IND-enabling program with sickle cell disease VOC as a potential lead indication.

Rivipansel

• GlycoMimetics completed and presented at the December ASH meeting a comprehensive review of the Phase 3 RESET data and for the first time, results of the OLE study. The analyses demonstrated that administration of rivipansel early during the cascade of VOC (within approximately 26-30 hours of the onset of VOC) resulted in statistically significant improvement on key clinical outcomes, particularly in the pediatric subgroup.
• Today, GlycoMimetics announced that rather than continuing to focus on rivipansel, it plans to take GMI-1687 forward toward an IND, with treatment of acute VOC as one possible use.

GMI-1359

• The Company has observed evidence of biologic activity in the initial patients treated in a Phase 1b proof-of-concept trial. The analyses are based on pharmacodynamic biomarkers, and have been submitted for presentation at a major medical meeting.

Executive Management Team

• The Company announced the promotion of Eric Feldman, M.D., to Senior Vice President and Chief Medical Officer in February 2021.

Fourth Quarter and Year-end 2020 Financial Results:

• Cash position: As of December 31, 2020, GlycoMimetics had cash and cash equivalents of $137.0 million as compared to $158.2 million as of December 31, 2019.
• Revenue: During the year ended December 31, 2020, the Company recognized revenue of $10.2 million, all of which was the result of payments received under our agreements with Apollomics for the development and commercialization of uproleselan and GMI-1687 in Greater China. There was no revenue recognized during the year ended December 31, 2019.
• R&D Expenses: The Company’s research and development expenses increased to $11.7 million for the quarter ended December 31, 2020 as compared to $11.5 million for the fourth quarter of 2019 due to higher clinical development expenses. Clinical expenses were higher as a result of increased number of sites and enrollment in the Company’s ongoing global Phase 3 clinical trial of uproleselan in individuals with relapsed/refractory AML.
  
  Research and development expenses for the year ended December 31, 2020 decreased to $44.9 million as compared to $47.0 million in the prior year. The decrease in expenses was due to lower raw material purchases in the year ended December 31, 2020 offset by the higher clinical development expenses resulting from the increased number of sites and enrollment in the Company’s ongoing global Phase 3 clinical trial of uproleselan in individuals with relapsed/refractory AML.
• G&A Expenses: The Company’s general and administrative expenses increased to $4.0 million for the quarter ended December 31, 2020 as compared to $3.9 million for the fourth quarter of 2019. General and administrative expenses for the year ended December 31, 2020 increased to $16.7 million as compared to $14.4 million in the prior year. These increases were due to a significant increase in the cost of directors and officers liability insurance in 2020 as compared to 2019. In addition, personnel-related and stock-based compensation expenses increased due to additional headcount, annual salary adjustments and retention bonuses. Other expenses decreased as compared to the prior year due to lower travel, meals and conference registration expenses as a result of travel restrictions due to the COVID-19 pandemic.
• Shares Outstanding: Shares of common stock outstanding as of December 31, 2020 were 49,017,622.

About Uproleselan

Discovered and developed by GlycoMimetics, uproleselan is an investigational, first-in-class, targeted inhibitor of E-selectin. Uproleselan (yoo’ pro le’ sel an), currently in a comprehensive Phase 3 development program in AML, has received Breakthrough Therapy designation from the U.S. FDA and from the Chinese NMPA for the treatment of adult AML patients with relapsed or refractory disease. Uproleselan is designed to block E-selectin (an adhesion molecule on cells in the bone marrow) from binding with blood cancer cells as a targeted approach to disrupting well-established mechanisms of leukemic cell resistance within the bone marrow microenvironment. In a Phase 1/2 clinical trial, uproleselan was evaluated in both newly diagnosed elderly and relapsed or refractory patients with AML. In both populations, patients treated with uproleselan together with standard chemotherapy achieved better-than-expected remission rates and overall survival compared to historical controls, which have been derived from results from third-party clinical trials evaluating standard chemotherapy, as well as lower-than-expected induction-related mortality rates. Treatment in these patient populations was generally well-tolerated, with fewer than expected adverse effects.

About GMI-1687

Discovered and developed by GlycoMimetics, GMI-1687 is a highly-targeted, highly-potent E-selectin antagonist. It has been shown in preclinical studies to be bioavailable via subcutaneous administration. During 2020, data from oral presentations at major scientific conferences pointed to the potential for a self-administered drug to treat VOC of sickle cell disease. Previously, GlycoMimetics has also demonstrated in preclinical models that GMI-1687 could be a potentially self-administered drug to be used in treatment of AML. The investigational drug also represents a potential life cycle extension opportunity for uproleselan.

About Rivipansel

Rivipansel, the Company’s wholly-owned glycomimetic drug candidate that binds to all three members of the selectin family (E-, P- and L-selectin), was GlycoMimetics’ first drug candidate to enter clinical development. Rivipansel has been granted a Rare Pediatric Disease designation for treatment of sickle cell disease in patients 18 years old and younger, and has also received Orphan Drug and Fast Track designations from the FDA. GlycoMimetics is discontinuing development of rivipansel as a treatment for VOC of sickle cell disease.

About GMI-1359

GMI-1359 is designed to simultaneously inhibit both E-selectin and CXCR4. E-selectin and CXCR4 are both adhesion molecules involved in tumor trafficking and metastatic spread. Preclinical studies indicate that targeting both E-selectin and CXCR4 with a single compound could improve efficacy in the treatment of cancers that involve the bone marrow such as AML and multiple myeloma or in solid tumors that metastasize to the bone, such as prostate cancer and breast cancer, as well as in osteosarcoma, a rare pediatric tumor affecting about 900 adolescents a year in the United States. GMI-1359 has completed a Phase 1 clinical trial in healthy volunteers. A Phase 1b clinical study is underway in breast cancer patients and is designed to enable investigators to identify an effective dose of the drug candidate and to generate initial biomarker data around the drug’s activity. GMI-1359 has received Orphan Drug designation and Rare Pediatric Disease designation from the FDA for the treatment of osteosarcoma.
