"We believe GMI-1271 has the potential to address important unmet needs for individuals with relapsed or refractory AML, as well as for older AML patients, for whom the standard of care often fails to provide outcomes as positive as those seen in other patient groups," said Helen Thackray, M.D., Chief Medical Officer of GlycoMimetics. "The FDA’s granting of a Fast Track designation for GMI-1271 to treat AML is an important step in advancing this drug candidate through the regulatory process, and if successful, in bringing a novel drug to patients in an expedited time frame."

The Fast Track Designation is designed to facilitate development and expedite review of experimental therapies that address the unmet medical needs of patients with serious conditions.

AML is a cancer of immature white blood cells that starts in the bone marrow but can quickly spread into the blood, lymph nodes, liver, spleen, central nervous system, and testicles. Each year in the United States, about 19,900 people (usually older than 45 years of age) are diagnosed, and about 10,400 people die from all forms of the disease, according to the American Cancer Society. Chemotherapeutic methods among patients with refractory and relapsed AML have low remission rates, between 25 and 30 percent.

GlycoMimetics announced on Friday, June 10, presentation of data from the Phase 1 portion of its on-going Phase 1/ 2 clinical trial testing GMI-1271 combined with induction chemotherapy, in patients with relapsed/refractory acute myeloid leukemia (AML). Data was reported at the European Hematology Association (EHA) (Free EHA Whitepaper)21stCongress in Copenhagen, Denmark in a poster entitled "Results of a Phase 1 study of GMI-1271, a potent E-selectin antagonist in combination with induction chemotherapy in relapsed/refractory AML: a novel, well-tolerated regimen with a high remission rate."

In addition, GlycoMimetics recently announced that the first patient with relapsed or refractory AML has been dosed in the company’s Phase 2 portion of the ongoing Phase 1/2 clinical trial of GMI-1271. This clinical trial is a multinational open-label study evaluating endpoints for safety, pharmacokinetics (PK) and efficacy of GMI-1271 in combination with induction chemotherapy in patients with high-risk AML. This trial is being conducted at a number of academic medical institutions in the United States, Ireland, and Australia. While the primary objective is to assess safety, additional endpoints include overall response rate, biomarkers of activity, durability of response and overall survival. The Phase 2 portion of the study is expected to include approximately 25 participants with relapsed or refractory AML and approximately 25 participants who are newly diagnosed.

About GMI-1271

GMI-1271 is designed to block E-selectin (an adhesion molecule on cells in the bone marrow) from binding with AML cells as a targeted approach to disrupting well-established mechanisms of leukemic cell resistance within the bone marrow microenvironment. Preclinical research points to the drug’s potential role in moving cancerous cells out of the protective environment of the bone marrow where they hide and escape the effects of chemotherapy. In preclinical studies using animal models of AML, the results of which were presented at meetings of the American Society of Hematology (ASH) (Free ASH Whitepaper), GMI-1271 was also associated with a reduction of chemotherapy-induced neutropenia and chemotherapy-induced mucositis.

On June 13, 2016 The Multiple Myeloma Research Foundation (MMRF), a leader in precision medicine, reported that its founder, Kathy Giusti, whom Fortune recently named as one of three business leaders who are disrupting medicine, has been appointed faculty co-chair of the Kraft Precision Medicine Accelerator at Harvard Business School (HBS) (Press release, Multiple Myeloma Research Foundation, JUN 13, 2016, View Source [SID:1234513283]).

Giusti, an alumna of HBS, will lead the Harvard Business School Kraft Precision Medicine Accelerator with HBS faculty member and co-chair Richard Hamermesh under the umbrella of the School’s Health Care Initiative. She will continue to act as a member of the MMRF Board of Directors and take an active role in the organization’s leadership.

The HBS Kraft Precision Medicine Accelerator is made possible by a $20M endowment from the Kraft Family Foundation, under the leadership of foundation President, Robert K. Kraft. The Kraft family, through its family foundation, is committed to giving back to the community. The foundation’s primary mission includes supporting education, healthcare, science, and the needs of underserved individuals.

"Precision medicine has the potential to revolutionize the way we prevent, diagnose, treat, and, ultimately, cure cancer and other devastating diseases. I look forward just as much to sharing the MMRF model as I do to learning best practices from other world-class organizations focused on this promising approach," said Ms. Giusti, who is also a multiple myeloma patient.

"The promise of precision medicine will only be realized if we abandon a siloed approach to research and work collaboratively toward a greater good – two approaches Kathy Giusti has embraced and advocated in her nearly two decades of service to the cancer community. I am certain her vision and leadership of the HBS/Kraft Precision Medicine Accelerator will greatly improve the lives of people with cancer and other diseases," said Robert Kraft.

The mission of the HBS/Kraft Precision Medicine Accelerator is to speed innovation and medical breakthroughs in precision medicine, the process by which genomic information and other unique characteristics of a person’s disease are used to predict which treatments will be most effective. The Accelerator will convene best-in-class leaders from the business, medical, scientific, and technological communities to identify and solve challenges slowing the advancement of precision medicine, disseminate best practices and models to overcome these challenges, and, ultimately, enable the faster commercialization of high-impact innovations.

"Many of the biggest challenges in advancing breakthroughs promised by precision medicine are business challenges—how to best develop and commercialize medical solutions for public benefit, and how to optimally share data, for example. HBS is uniquely positioned to address these challenges by drawing on the ingenuity and expertise of our faculty, alumni, and students, and by convening the leaders who can develop innovative new models," said HBS Dean Nitin Nohria.

On June 12, 2016 Pfizer Inc. today reported the publication of findings from the Phase 3 INO-VATE ALL study in the online issue of The New England Journal of Medicine (Press release, Pfizer, JUN 12, 2016, View Source [SID:1234513240]). The study, also known as Study 1022, is an open-label, randomized, Phase 3 study evaluating the safety and efficacy of inotuzumab ozogamicin as compared with investigator-choice chemotherapy in 326 adult patients with relapsed or refractory CD22-positive acute lymphoblastic leukemia (ALL). Results showed improvement over chemotherapy on a number of measures including complete hematologic remission and progression-free survival (PFS). Updated results and newly available overall survival (OS) data were also presented as a late-breaking oral presentation (#LB2233) today at the 21st Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) 2016 Annual Meeting in Copenhagen, Denmark.

"Relapsed or refractory ALL is an aggressive leukemia in urgent need of new treatment options as about half of adult patients will not respond to chemotherapy or will see their disease return," said Hagop M. Kantarjian, M. D., lead study investigator and professor, The University of Texas MD Anderson Cancer Center. "The efficacy results seen in patients treated with inotuzumab ozogamicin in this study are impressive, particularly median progression-free survival, high rates of hematological remission and absence of minimal residual disease. These results suggest inotuzumab ozogamicin, if approved, could be a valuable new addition to currently available treatment options for ALL patients, including as a bridge to stem cell transplantation, which is the best chance for a cure at this stage of the disease."

The INO-VATE ALL study had two independent primary endpoints, complete response with or without hematologic remission and OS. INO-VATE ALL met its first primary endpoint of complete response, which was significantly better with inotuzumab ozogamicin compared to chemotherapy (80.7% [95% CI, 72%-88%] vs. 29.4% [95% CI, 21%-39%], P<0.001). Inotuzumab ozogamicin also significantly extended PFS compared to chemotherapy (HR: 0.45 [97.5% CI, 0.34-0.61], P<0.001; median PFS, 5.0 vs. 1.8 months, in their respective arms). The second primary endpoint of OS showed a strong trend toward longer OS for patients treated with inotuzumab ozogamicin compared to chemotherapy, but did not reach the level of statistical significance (p < 0.0104) for the trial (HR: 0.77 [97.5% CI, 0.58-1.03], one-sided P=0.0203; median OS, 7.7 months [95% CI, 6.0-9.2] vs. 6.7 months [95% CI, 4.9-8.3]). The two-year OS rate for inotuzumab ozogamicin was 23 percent (95% CI, 16%‒30%) compared to chemotherapy at 10 percent (95% CI, 5%‒16%).

"Adult patients with relapsed or refractory ALL have a five-year survival rate of less than 10 percent, making these patients particularly difficult to treat. To see remission rates and two-year survival rates that are more than doubled compared to standard of care chemotherapy is very gratifying. We believe these data add to the growing body of evidence that supports inotuzumab ozogamicin as an important potential treatment option in adults with relapsed or refractory ALL," said Mace Rothenberg, MD, Chief Development Officer, Oncology, Pfizer Global Product Development.

Results from INO-VATE ALL also showed patients treated with inotuzumab ozogamicin achieved high rates of minimal residual disease (MRD) negativity (78.4% [95% CI, 68%-87%; P<0.001]), and experienced a duration of response (DOR) of 4.6 months (95% CI, 3.9-5.4; HR: 0.55; P<0.034). In comparison, 28.1 percent (95% CI, 14%-47%; P<0.001) of patients treated with chemotherapy achieved MRD negativity and median DOR was 3.1 months (95% CI, 1.4-4.9; HR: 0.55; P<0.034). More patients also proceeded to stem-cell transplant with inotuzumab ozogamicin compared to standard chemotherapy (41% vs. 11%, P<0.001).

The most common adverse events (AEs) observed for both inotuzumab ozogamicin and chemotherapy were cytopenias, including febrile neutropenia (16% vs. 22%). Common nonhematologic treatment-emergent AEs with inotuzumab ozogamicin included nausea (32%), headache (28%) and pyrexia (27%). Patients in the chemotherapy arm experienced nausea (47%), pyrexia (43%) and diarrhea (40%).

Additionally, any-grade veno-occlusive liver disease (VOD) occurred more frequently in patients treated with inotuzumab ozogamicin compared to chemotherapy (11% vs. 1%). Five patients taking inotuzumab ozogamicin developed VOD during treatment and 10 patients developed VOD after subsequent stem cell transplant. Among those taking chemotherapy, one patient developed VOD after transplant; no cases of VOD occurred during treatment with chemotherapy.

Inotuzumab ozogamicin received Breakthrough Therapy designation from the U.S. Food and Drug Administration (FDA) for ALL in October 2015. Pfizer is working closely with the FDA and other regulatory authorities with the aim of making inotuzumab ozogamicin available for adult patients with relapsed or refractory CD22-positive ALL.

About Acute Lymphoblastic Leukemia (ALL)

Acute lymphoblastic leukemia (ALL) is an aggressive type of leukemia with a poor prognosis in adults.1 The current foundational treatment is intensive, long-term chemotherapy.2 In 2016, it is estimated that 6,590 cases of ALL will be diagnosed in the United States, with about 2 in 5 cases in adults.3 Approximately 20 to 40 percent of newly diagnosed adults with ALL are cured with current treatment regimens.4 For patients with relapsed or refractory adult ALL, the five-year overall survival rate is less than 10 percent.5

About Inotuzumab Ozogamicin

Inotuzumab ozogamicin is an investigational antibody-drug conjugate (ADC) comprised of a monoclonal antibody (mAb) targeting CD22, a cell surface antigen found on cancer cells in almost all B-ALL patients, linked to a cytotoxic agent. 1,6 When inotuzumab ozogamicin binds to the CD22 antigen on malignant B-cells, it is thought to be internalized into the cell, where the cytotoxic agent calicheamicin is released to destroy the cell.7

Inotuzumab ozogamicin originates from a collaboration between Pfizer and Celltech, now UCB. Pfizer has sole responsibility for all manufacturing and clinical development activities for this molecule.

On June 11, 2016 Boehringer Ingelheim reported that the results of the Phase III POLO-AML-2 trial investigating volasertib plus chemotherapy (low dose cytarabine, LDAC), in the treatment of elderly acute myeloid leukemia (AML) patients, did not meet the primary endpoint of objective response (Press release, Boehringer Ingelheim, JUN 11, 2016, View Source [SID:1234513209]). Boehringer Ingelheim is committed to further investigating volasertib with a revised research strategy based on the learnings of the trial, which demonstrated the compound’s anti-leukemic activity and an increased response rate.

The results, presented at the 21st Annual Congress of the European Hematology Association (EHA) (Free EHA Whitepaper) 2016, showed the percentage of patients with an objective response was higher with volasertib plus LDAC, compared to placebo plus LDAC, but the difference was statistically not significant. The data showed an unfavorable overall survival trend for the experimental treatment arm, with the safety profile of the volasertib plus LDAC dosing regimen considered as the main reason for the trend.

Martin Stefanic, Medical Head, Early Clinical Development, Boehringer Ingelheim commented: "We are disappointed with the findings of the POLO-AML-2 trial after the encouraging results we observed in the Phase II trial. However, we believe in the potential of volasertib and new clinical studies have been initiated for AML patients, in addition to other areas of high unmet need such as higher risk myelodysplastic syndromes (MDS). The goal of these studies is to improve tolerability with modified dosing and scheduling of volasertib, while not compromising on efficacy, in order to achieve the best outcome for patients."

POLO-AML-2 (NCT01721876) is a randomized, double-blind, multi-center, controlled Phase III clinical trial of volasertib in combination with LDAC in 666 patients aged 65 years and older with newly diagnosed AML, not suitable for intensive induction therapy. The primary analysis showed a higher number of patients responded to volasertib plus LDAC (25.2%) than placebo plus LDAC (16.8%) but the overall result was not statistically significant.

There was a higher incidence of severe adverse events with volasertib plus LDAC, with a fatal infection frequency of 16.6% (volasertib plus LDAC) vs 5.1% (placebo plus LDAC) which was considered the main reason for a negative overall survival trend in the volasertib plus LDAC treatment arm compared to placebo plus LDAC (primary OS analysis: HR 1.26 [95% CI 0.95–1.67; p=0.113]; updated OS analysis (Nov 2015): HR 1.06 [95% CI 0.88–1.28; p=0.552]). The unblinded trial is still ongoing and updated results will be presented at a future scientific meeting when they are available.

Boehringer Ingelheim has a substantial program in hematological cancers with five investigational compounds in early clinical development.

About volasertib
Volasertib is an investigational compound that inhibits enzymes called Polo-like kinases (PLKs). Inhibition of PLK1 by volasertib ultimately results in cell death (apoptosis). By inhibiting PLK1 activity, the extremely high cell division that is characteristic of AML should be blocked, which may result in cancer regression.
