ROCKVILLE, Md.--(BUSINESS WIRE)--Aug. 1, 2019-- GlycoMimetics, Inc. (Nasdaq: GLYC) today reported its financial results for the quarter ended June 30, 2019 and highlighted recent business achievements. Quarter-end cash and cash equivalents were $184.2 million.

“In the second quarter of 2019, Pfizer completed enrollment in the pivotal Phase 3 trial of rivipansel and has recently given public guidance that it expects to report topline results in the third quarter of the year. We eagerly await those results, which will mark an important milestone for GlycoMimetics. In parallel, we continued to progress the late-stage clinical development of our uproleselan product candidate. Our Phase 3 trial in relapsed or refractory AML patients and the NCI-sponsored Phase 3 trial for newly diagnosed patients with AML both advanced during the quarter, with initiation of new sites and patient enrollment underway. During the same period, with our clinical collaborators at Duke Cancer Institute, we progressed our plans for a single center, proof-of-concept Phase 1b trial for GMI-1359, our dual antagonist of E-selectin and CXCR-4, in breast cancer patients with bone metastases,” said Rachel King, GlycoMimetics’ Chief Executive Officer.

Key Second-Quarter 2019 and Recent Operational Highlights:

• Pfizer completed enrollment in the Phase 3 trial of rivipansel in individuals with SCD experiencing vaso-occlusive crisis (VOC).
• GlycoMimetics’ pivotal Phase 3 trial of uproleselan in relapsed/refractory AML continued to initiate and activate clinical sites and to enroll patients in the US, Australia and now in Europe.
• Investigators initiated enrollment in the NCI-sponsored Phase 3 clinical trial designed to evaluate uproleselan in newly diagnosed older adults with AML who are fit for chemotherapy.
• Start-up activities continued for the collaborative Haemato Oncology Foundation for Adults in the Netherlands (HOVON) European Phase 2 trial of uproleselan in newly diagnosed patients unfit for chemotherapy.
• The Company announced plans to initiate a Phase 1b proof-of-concept clinical trial of GMI-1359 in individuals with breast cancer whose tumors have spread to bone. The trial will evaluate safety and biomarkers of cancer cell mobilization in individuals with hormone receptor positive metastatic breast cancer. The trial will be conducted at Duke University.
• Data were published in Nature Cell Biology that strongly suggest E-selectin is key to tumor growth and metastasis to bone and provide further support for the planned clinical trial of GMI-1359 in individuals with metastatic breast cancer.
• Eric Feldman, M.D., joined the GlycoMimetics executive team as Vice President, Clinical Development, and Christian Dinneen-Long, J.D., joined as Vice President, Corporate Counsel.

Second Quarter 2019 Financial Results:

• Cash position: As of June 30, 2019, GlycoMimetics had cash and cash equivalents of $184.2 million as compared to $209.9 million as of December 31, 2018.
• R&D Expenses: The Company’s research and development expenses increased to $13.1 million for the quarter ended June 30, 2019 as compared to $9.3 million for the second quarter of 2018. This increase was primarily the result of expenses relating to the Company’s Phase 3 clinical trial of uproleselan in relapsed or refractory AML patients and supporting the clinical trials of uproleselan conducted by or in collaboration with third parties.
• G&A Expenses: The Company’s general and administrative expenses increased to $3.8 million for the quarter ended June 30, 2019 as compared to $2.8 million for the quarter ended June 30, 2018. The increase was due to higher patent, legal and non-cash stock-based compensation expenses.
• Shares Outstanding: Shares outstanding as of June 30, 2019 were 43,193,190.

About Rivipansel

Rivipansel, the most advanced drug candidate in the GlycoMimetics pipeline, is a glycomimetic drug candidate that acts as a pan-selectin antagonist, meaning it binds to all three members of the selectin family: E-, P- and L-selectin. The first potential indication for rivipansel is VOC, one of the most severe complications of SCD that can result in acute ischemic organ injury at one or more sites. By reducing cell adhesion, activation and inflammation that are believed to contribute to reduced blood flow through the microvasculature during VOC, GlycoMimetics believes that rivipansel could be the first drug to interrupt the underlying cause of VOC, thereby potentially enabling patients to leave the hospital more quickly. In June 2019, Pfizer Inc., the exclusive licensee of rivipansel for clinical development and worldwide commercialization, completed its Phase 3 trial to evaluate the efficacy and safety of rivipansel in the treatment of VOC in hospitalized patients with SCD. Topline results from this clinical trial are expected in the third quarter of 2019.

About Uproleselan (GMI-1271)

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. Food and Drug Administration (FDA) 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-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. GMI-1359 has completed a Phase 1 clinical trial in healthy volunteers. In the second half of 2019, the Company plans to initiate an exploratory clinical trial in individuals with breast cancer whose tumors have spread to bone.
