GlycoMimetics Announces Enrollment of First Patient in NCI-Sponsored Phase 3 Trial of Uproleselan in AML

On April 23, 2019 GlycoMimetics, Inc. (NASDAQ: GLYC) reported dosing of the first patient in a Phase 3 clinical trial being conducted under the auspices of a Cooperative Research and Development Agreement (CRADA) between GlycoMimetics and the National Cancer Institute (NCI), part of the National Institutes of Health (Press release, GlycoMimetics, APR 23, 2019, View Source [SID1234535330]). The second in a series of trials designed to evaluate uproleselan across the continuum of care in AML, this NCI-sponsored study is evaluating the addition of uproleselan to a standard cytarabine/daunorubicin regimen (7&3) in older adults with previously untreated AML who are suitable for intensive chemotherapy. A third trial, to be conducted by the European HOVON consortium, is expected to initiate later this year.

"The initiation of the NCI-sponsored trial is an important milestone for our uproleselan program, a drug candidate with the potential to address significant unmet treatment needs across the spectrum of AML," noted Helen Thackray, M.D., FAAP, GlycoMimetics Senior Vice President, Clinical Development, and Chief Medical Officer. "Along with our global pivotal Phase 3 clinical trial testing the investigational drug in patients with relapsed/refractory acute myeloid leukemia, this trial will facilitate our growing understanding of how uproleselan may fit into the continuum of care for individuals living with AML."

GlycoMimetics is collaborating with both the NCI and the Alliance for Clinical Trials in Oncology to conduct the trial, which is led by Geoffrey Uy, M.D., Associate Professor of Medicine, Bone Marrow Transplantation and Leukemia, Washington University School of Medicine in St. Louis. The primary endpoint will be overall survival, with a planned interim analysis based on event-free survival (EFS) after the first 250 patients have been enrolled in the study. More information on this clinical trial can be found at www.clinicaltrials.gov.

New data on uproleselan-treated high-risk patients with both relapsed/refractory and newly diagnosed AML were presented at an oral session during the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition in December 2018. An analysis of clinical outcomes from the Phase 1/2 clinical study showed that uproleselan (GMI-1271) resulted in the majority of evaluable patients achieving a stringent level of measurable residual disease (MRD) negativity, an effect which translated into extended survival relative to matched, historical controls.

About Uproleselan (GMI-1271)

uproleselan (yoo’ pro le’ sel an) 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/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. The U.S. Food and Drug Administration (FDA) has granted uproleselan Breakthrough Therapy Designation for the treatment of adult AML patients with relapsed/refractory (R/R) disease. GlycoMimetics is implementing a comprehensive development program across the clinical spectrum of AML.

OncoSec Announces Triple Combination Immunotherapy Clinical Trial Of TAVO™, Epacadostat And KEYTRUDA® In Squamous Cell Head And Neck (SCCHN) Cancer

On April 23, 2019 OncoSec Medical Incorporated (OncoSec) (NASDAQ:ONCS), a company developing intratumoral cancer immunotherapies, reported a triple combination clinical trial of OncoSec’s TAVO, epacadostat, and KEYTRUDA in patients with squamous cell carcinoma head and neck (SCCHN) cancer (Press release, OncoSec Medical, APR 23, 2019, View Source [SID1234535327]). This study, the "TRIFECTA" study, will be conducted by the UCSF Helen Diller Family Comprehensive Cancer Center.

TRIFECTA, formally entitled, "The Trifecta Study: Optimizing Antitumor Immunity Using Tavokinogene Telseplasmid with Electroporation, Pembrolizumab, and Epacadostat in Squamous Cell Carcinoma of the Head and Neck," will evaluate the combination use of OncoSec’s TAVO (intratumoral IL-12 tavokinogene telseplasmid), epacadostat (IDO inhibitor), and KEYTRUDA (pembrolizumab, an anti-PD1 monoclonal antibody) in patients with SCCHN cancer.

TRIFECTA will be an investigator-initiated clinical trial by UCSF otolaryngologist, Dr. Chase Heaton, to determine whether the triple combination can increase the overall response rate (ORR) in SCCHN compared with historical data for KEYTRUDA as a monotherapy. The costs of this clinical trial will be shared with others and will require minimal financial commitment from OncoSec.

The response rate in patients with unresectable SCCHN is very low when treated with anti-PD1 antibodies as a monotherapy, with only 13-16%1 2 durable remissions. Treatment failures are more common in patients whose tumors either lack anti-tumor immune cells or have an overabundance of regulatory immune cells that suppress effective anti-tumor immune responses. TAVO has previously demonstrated the ability to reverse this type of anti-PD-1 resistance in patients with metastatic melanoma.

"Effective anticancer immune responses require three steps, including immune priming and tumor infiltration with T cells; activation of partially exhausted TILs; and selective modulation of T cell populations to maximize the ratio of effector to regulatory immune cells," said Dr. Alain Algazi, Associate Professor of Clinical Medicine at UCSF and Clinical Strategic Advisor to OncoSec. "Based on this framework, we hypothesize that the combination of TAVO’s tumor infiltration mechanism, with pembrolizumab’s TIL technology and epacadostat’s T cell modulating capabilities will substantially increase the ORR to pembrolizumab in patients with SCCHN and that the combination will be well tolerated in this population."

TRIFECTA is a single-arm open-label clinical trial in which 35 evaluable patients will receive TAVO, pembrolizumab, and epacadostat. The primary endpoint of the study is overall response rate (ORR) by RECIST v1.1 and will be compared to historical data for pembrolizumab monotherapy in SCCHN and to existing data regarding the combination of pembrolizumab and epacadostat.

Melanoma patients in the anti-PD-1 refractory setting have found renewed clinical responses with the combination of KEYTRUDA with TAVO in the KEYNOTE-695 trial. TAVO’s mechanism of action may also enhance the activity of epacadostat as expression of IDO is driven by IFN-g, which, in TAVO-treated patients may create a broader target and therefore opportunity to limit this suppressive IDO axis. Due to its favorable safety profile, clinical activity and ability to trigger adaptive resistance (increases in both IDO and PD-L1 expression) via a robust IFN-g response, TAVO is a strong backbone for a combination strategy with epacadostat and Merck’s anti-PD-1 antibody, pembrolizumab.

"Supporting this investigator-initiated clinical is a very cost-effective way to learn if the three-way combination of TAVO, epacadostat and pembrolizumab can significantly improve the historical anti-PD-1 monotherapy durable remission response rate of 13-16%," said Daniel O’Connor, President and Chief Executive Officer of OncoSec. "Studies such as these continue to build on the body of clinical evidence in support of TAVO in a variety of combination therapies. We believe it is important to support investigator led studies such as this one, especially considering the prestige of the medical institution and the oncologists involved."
