This multicenter, open-label phase II study combines CLAG-based therapy with or without venetoclax in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) in order to improve measurable residual disease (MRD) clearance and event-free survival. Investigators hypothesize that the addition of venetoclax to CLAG-M in patients with relapsed or refractory AML is safe, and superior to CLAG-M alone in improving patient outcomes.

Redefining Anthraquinone-based Anticancer Drug Design through Subtle Chemical Modifications

Article

Author: De, Utpal Chandra ; Mishra, Bijayashree ; Acharya, Pratap Chandra

Anthraquinones are well known for their wide spectrum of pharmacological properties. Anthraquinone antibiotics, such as doxorubicin, daunorubicin, epirubicin, and mitoxantrone, have long been used in the clinical management of various tumors. However, their use is limited due to their toxicity effects, especially cardiomyopathy, despite their pronounced therapeutic effects. In recent years, medicinal chemists have explored the possibility of modifying the anthraquinone ring appended with structurally diverse functionality in order to develop better chemotherapeutic agents with fewer adverse effects. The fused polycyclic structure of anthraquinone offers rigidity, planarity, and aromaticity, which helps in double helix DNA intercalation, disruption of G4 DNA, and inhibition of topoisomerase-II enzyme of cancer cells, making them suitable pharmacophore for anticancer drug discovery. Incorporation of suitable functional groups such as amino, hydroxyl, and their derivatives into anthraquinone rings can improve their interactions with biological targets involved in cancer progression. These subtle structural changes produce newer anthraquinone derivatives with improved anticancer properties, increased potency, selectivity, and reduced toxicity, and can overcome multi-drug resistance. On the other hand, the molecular hybrids of the anthraquinone derivatives have been reported to act on multiple targets in cancer cells, as seen in the case of clinical candidates like alectinib, midostaurin, tucatinib, belinostat, and dacinostat. Molecular hybrid has given a new direction for anticancer drug development, which can produce bifunctional drug candidates with reduced toxicity. This review summarizes different structural modifications that have been made to the anthraquinone ring in the last decade with the aim of bringing out potent yet toxicity-free anticancer agents.

Effective cancer immune therapy requires the orchestration of antigen induction, presentation and T-cell activation, further enhanced by anti-angiogenesis treatment; therefore, multiple therapeutics are generally used for such combination therapy. Herein, we report esterase-hydrolysable cationic polymers, N-[3-((4-acetoxy benzyl) oxy)-3-oxopropyl]-N-methyl-quaternized PEI (ERP) and poly{N-[2-(acryloyl-oxy) ethyl]-N-[p-acetyloxyphenyl]-N,N-dimethylammonium chloride} (PQDMA), capable of simultaneously inducing tumor cell immunogenic cell death (ICD) to release antigens, activating the cGAS-STING pathways of tumor macrophages and dendritic cells, and releasing antiangiogenic agent p-hydroxybenzyl alcohol (HBA). Thus, intratumoral injection of ERP or PQDMA systemically boosted the anti-cancer immunities and inhibited tumor angiogenesis in mouse hepatocellular carcinoma and melanoma bilateral tumor models, leading to more effective tumor growth inhibition of both treated and abscopal untreated tumors than ICD alone induced by mitoxantrone and control cationic polymers. Further study using gene knockout mice and transcriptome sequencing analysis confirmed the involvement of cGAS-STING and type I IFN signaling pathways. This work demonstrates ERP and PQDMA as the first examples of inherent therapeutic polymers, accomplishing systemic tumor inhibition without combining other therapeutic agents.

Antiproliferative Activity of Cephalotaxus Esters: Overcoming Chemoresistance

Article

Author: Djaballah, Hakim ; Yong-Gonzalez, Vladimir ; Shum, David ; Frattini, Mark G. ; Calder, Paul A. ; Gin, David Y. ; Radu, Constantin

Introduction::

Omacetaxine, a semisynthetic form of Homoharringtonine (HHT), was approved for the treatment of Chronic Myeloid Leukemia (CML). Previously, we have published the synthesis of this natural alkaloid and three of its derivatives: Deoxyharringtonine (DHT), Deoxyhomoharringtonine (DHHT), and Bis(demethyl)-deoxyharringtonine (BDHT), and reported its refractory activity against the HL-60/RV+ cells over-expressing P-glycoprotein 1 (MDR1).

Methods::

In this study, we have explored the extent of this resistance by first expanding the panel of established cell lines and using a panel of 21 leukemia patient-derived primary cells.

Results::

Herein, we have reported consistent resistance to HTT of K562-derived cells and to mitoxantrone of MES-SA/MX2-derived cells; all of them have been found to overexpress MDR1, while we have found U87MG-ABCG2 and H69AR cells to be very sensitive to HTT. In contrast, DHT, DHHT, and BDHT seemingly overcame this resistance due to the changes made to the acyl chain of HTT, rendering the derivatives less susceptible to efflux. Surprisingly, the leukemia primary cells were very sensitive to HHT and its derivatives with low nanomolar potencies, followed by a new class of CDC7 kinase inhibitors, the anthracycline class of topoisomerase inhibitors, the DNA intercalator actinomycin-D, and the vinca alkaloid class of microtubule inhibitors. The mechanism of cell death induced by HTT and DHHT was found to be mediated via caspase 3 cleavage, leading to apoptosis.

Conclusion::

Taken together, our results confirm that HHT is a substrate for MDR1. It opens the door to a new opportunity to clinically evaluate HHT and its derivatives for the treatment of AML and other cancers.

ADC Therapeutics Announces The Lancet Haematology Publication of Data from Investigator-Initiated Trial Evaluating ZYNLONTA® in Combination with Rituximab to Treat Relapsed/Refractory Follicular Lymphoma

Publication follows oral presentation at the American Society of Hematology (ASH) Annual Meeting Combination in r/r follicular lymphoma shows best ORR of 97% and CR rate of 77% with 12-month PFS of 95% Additional IIT data also presented at ASH on ZYNLONTA monotherapy in marginal zone lymphoma shows ORR of 91% and 70% CR LAUSANNE, Switzerland, Dec. 9, 2024 /PRNewswire/ -- ADC Therapeutics SA (NYSE: ADCT), a commercial-stage global leader and pioneer in the field of antibody drug conjugates (ADCs), today announced updated data from the investigator-initiated Phase 2 clinical trial evaluating ZYNLONTA® (loncastuximab tesirine-lpyl) in combination with rituximab to treat relapsed or refractory (r/r) follicular lymphoma (FL) were published in the December issue of The Lancet Haematology, following an oral presentation of the data at the recent 66th American Society of Hematology (ASH) Annual Meeting and Exposition. "We are excited by the publication of these results in The Lancet Haematology demonstrating ZYNLONTA's robust clinical activity in follicular lymphoma, particularly in patients classified as high-risk POD24 and those with high tumor burden where there remains significant unmet need," said Mohamed Zaki, MD, PhD, Chief Medical Officer of ADC Therapeutics. "In addition, encouraging data from another investigator-initiated trial of ZYNLONTA as a single agent to treat marginal zone lymphoma were also presented at ASH. Collectively, we believe these data underscore ZYNLONTA's promise for patients with indolent B-cell lymphomas and add to a growing body of evidence showing the potential of ZYNLONTA beyond diffuse large B-cell lymphoma." ZYNLONTA in combination with rituximab to treat r/r follicular lymphoma (FL) The investigator-initiated trial conducted at the Sylvester Comprehensive Cancer Center at the University of Miami Miller School of Medicine evaluated the combination in patients with r/r FL treated with ≥1 line of systemic therapy presenting high-disease burden as defined by GELF criteria or POD24 at enrollment. The primary endpoint of the study is complete response rate (CR) by week 12 PET/CT based on Lugano 2014 criteria. The trial enrolled 39 patients, all of which were evaluated for safety and 35 of which were evaluated for efficacy. Patients were a median age of 68 years (range 47 to 89) and the majority received one previous line of therapy (n=26; 67%). R-CHOP was the most common first-line therapy (n=22; 56%) followed by bendamustine with rituximab (n=10; 26%), single-agent rituximab (n=6; 15%) and fludarabine, mitoxantrone and dexamethasone (n=1; 3%). Highlights from the results published in The Lancet Haematology included: Best overall response rate (ORR) of 97.4% (n=38) and CR rate of 76.9% (n=30) After a median follow-up of 15.6 months, the median progression-free survival (PFS) was not reached, and the 12-month PFS was 94.6% The most common treatment-emergent adverse events (TEAEs) were hyperglycemia (n=17; 43.6%) followed by increased alkaline phosphatase (n=16; 41%) and neutropenia, fatigue and increased aspartate aminotransferase and alanine aminotransferase (n=15; 38.5%) The most common grade ≥3 TEAE were lymphopenia (n=8; 20.5%) followed by neutropenia (n=5; 12.9%) No Grade 5 TEAEs occurred. The publication titled, "Loncastuximab tesirine with rituximab in patients with relapsed or refractory follicular lymphoma: a single centre, single arm Phase 2 trial," is now available online and will be published in the December issue of The Lancet Haematology. The results were also presented during a session on indolent B-cell lymphomas at ASH by Juan Pablo Alderuccio, MD, lead investigator and Associate Professor of Medicine and Hematologist at Sylvester. More details on the trial can be found at (identifier: NCT04998669). ZYNLONTA as a single agent to treat r/r marginal zone lymphoma (MZL) Data from an open-label, multi-institutional investigator-initiated trial evaluating the safety and efficacy of ZYNLONTA in 23 adult r/r MZL patients, previously treated with ≥1 line of systemic therapy, were also shared as a poster presentation at ASH by lead investigator, Izidore Lossos, MD, Professor of Medicine and Chief of the Lymphoma Section of the Division of Hematology at the Sylvester Comprehensive Cancer Center, University of Miami. The median age in this study was 65 years (range 45-82). The median number of previous treatments was 2 (range 1 to 4). As of October 15, 2024, 23 patients were evaluable for response. Highlights from the results presented include: ORR of 91% (n=21); 70% CR (n=16). ZYNLONTA led to CR in 7 of 11 patients (64%) with POD24 assessed for response and one patient who progressed after CAR-T. All but 1 CR are currently maintained with the longest follow-up of 27 months from the start of treatment (median duration of CR is 11.5 months). All of the 23 enrolled patients experienced expected adverse events (AE), most commonly grade 1 or 2. Grade 3 and 4 AEs were observed in 15 and 1 (neutropenia) patients, respectively. Local edema was observed in 10 (43.4%) patients. Three patients needed dose reduction and one patient discontinued treatment after cycle 4 because of cholestatic hepatitis. The patient clinically fully recovered with normalization in liver function test abnormalities. More details on this ongoing Phase 2 clinical trial can be found at (identifier: NCT05296070). About ZYNLONTA® (loncastuximab tesirine-lpyl) ZYNLONTA® is a CD19-directed antibody drug conjugate (ADC). Once bound to a CD19-expressing cell, ZYNLONTA is internalized by the cell, where enzymes release a pyrrolobenzodiazepine (PBD) payload. The potent payload binds to DNA minor groove with little distortion, remaining less visible to DNA repair mechanisms. This ultimately results in cell cycle arrest and tumor cell death. The U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have approved ZYNLONTA (loncastuximab tesirine-lpyl) for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified (NOS), DLBCL arising from low-grade lymphoma and also high-grade B-cell lymphoma. The trial included a broad spectrum of heavily pre-treated patients (median three prior lines of therapy) with difficult-to-treat disease, including patients who did not respond to first-line therapy, patients refractory to all prior lines of therapy, patients with double/triple hit genetics and patients who had stem cell transplant and CAR-T therapy prior to their treatment with ZYNLONTA. This indication is approved by the FDA under accelerated approval and in the European Union under conditional approval based on overall response rate and continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

GlycoMimetics Announces Comprehensive Results from Pivotal Phase 3 Study of Uproleselan in Relapsed/Refractory (R/R) Acute Myeloid Leukemia (AML)

Company exploring path forward for uproleselan in multiple AML settings based on observed efficacy results, including clinically meaningful results in primary refractory AML, and significant unmet patient need Uproleselan demonstrated a clinically meaningful improvement in median overall survival (mOS) for patients with primary refractory AML; mOS was 31.2 months for the uproleselan arm compared to 10.1 months for the placebo arm in this subgroup Adverse events for uproleselan were consistent with known side effect profiles of chemotherapy used in the study Advancing discussions with the National Cancer Institute (NCI) and the Alliance for Clinical Trials in Oncology for Phase 2/3 study of uproleselan with chemotherapy in older adults with frontline AML Conference call and webcast to be hosted today, June 4, 2024, at 8:30 am E.T. ROCKVILLE, Md.--(BUSINESS WIRE)-- GlycoMimetics, Inc. (Nasdaq: GLYC), a late clinical-stage biotechnology company discovering and developing glycobiology-based therapies for cancers and inflammatory diseases, today announced comprehensive results from the company’s pivotal Phase 3 study of uproleselan in R/R AML. “There is a wealth of data across large subsets of this pivotal Phase 3 study that help us understand how prespecified stratification factors such as backbone chemotherapy, disease status, and age impacted survival outcomes for patients,” said Daniel DeAngelo, M.D., Ph.D., Professor of Medicine, Harvard Medical School, Chief, Division of Leukemia, Dana-Farber Cancer Institute, and Principal Investigator of the pivotal Phase 3 study. “In the primary refractory setting, uproleselan’s improvement of mOS and greater duration of remission were particularly compelling, as there is a significant unmet need for new treatment options in this setting that can extend and improve the lives of patients. These results demonstrate uproleselan has the potential to address this unmet need in primary refractory AML.” “As we have analyzed data from this large, well-balanced, and well-executed study alongside medical, statistical, and regulatory experts, it has become clear that uproleselan may offer clinically meaningful patient benefit in multiple settings, including primary refractory AML,” said Harout Semerjian, Chief Executive Officer of GlycoMimetics. “We are committed to addressing unmet needs of AML patients and plan to engage with regulators and NCI to discuss potential paths forward for uproleselan.” Results of Pivotal Phase 3 Study of Uproleselan in R/R AML The randomized, double-blind, placebo-controlled Phase 3 clinical study evaluated uproleselan in combination with MEC (mitoxantrone, etoposide and cytarabine) or FAI (fludarabine, cytarabine and idarubicin) in patients with R/R AML. Patients received either uproleselan or placebo for 8 days over 1 cycle of induction and, if applicable, up to 3 cycles of consolidation. The primary endpoint was overall survival (OS), which was not censored for transplant. Secondary endpoints included incidence of severe oral mucositis, complete remission (CR) rate and CR with partial hematologic recovery (CRh). A total of 388 patients in nine countries were randomized 1:1 between treatment and placebo arms. There were 59 sites that enrolled at least one patient. Median follow up was over three years at the time of primary analysis. Overall Survival Primary Endpoint: mOS in the intent-to-treat (ITT) population (n=388) was 13.0 months for the uproleselan arm, compared to 12.3 months for the placebo arm (hazard ratio [HR] 0.89; 95% confidence interval [CI] 0.69-1.15); this difference is not statistically significant. Disease Status Primary Refractory: mOS for primary refractory patients in the uproleselan arm (n=62) was 31.2 months, compared to 10.1 months (HR 0.58; 95% CI 0.37-0.91) for the placebo arm (n=66). This benefit was irrespective of backbone chemotherapy. Median duration of response (DoR) for complete remission (CR) was not reached for primary refractory patients in the uproleselan arm compared to a median DoR of 12.7 months for the placebo arm. Early Relapse: mOS for early relapse patients in the uproleselan arm (n=28) was 3.7 months, compared to 6.4 months (HR 1.50; 95% CI 0.69-3.27) for the placebo arm (n=22). Late Relapse: mOS for late relapse patients in the uproleselan arm (n=104) was 15.4 months, compared to 18.2 months (HR 1.10; 95% CI 0.77-1.57) for the placebo arm (n=106). Backbone Chemotherapy: FAI: mOS for patients treated with uproleselan plus FAI (n=98) was 30.2 months compared to 12.8 months (HR 0.73; 95% CI 0.50-1.06) for patients treated with FAI alone (n=96) in the ITT population. MEC: mOS for patients treated with uproleselan plus MEC (n=96) was 8.7 months compared to 12.3 months (HR 1.06; 95% CI 0.75-1.51) for patients treated with MEC alone (n=98) in the ITT population. Transplantation Status: For patients who received hematopoietic stem cell transplantation (HSCT) after study treatment, mOS was not reached for patients in the uproleselan arm (n=101). In contrast, for HSCT patients in the placebo arm, mOS for patients receiving FAI (n=53) was 26.3 months and for patients receiving MEC (n=46) was 24.4 months. Secondary Endpoints 7.2% of patients in each arm (n=388) experienced induction emergent severe oral mucositis. 36.1% of patients in the uproleselan arm (n=194) experienced CR at the end of induction (EOI) as determined by an independent endpoint review committee (IERC), compared to 33.5% of patients in the placebo arm (n=194). 46.4% of patients in the uproleselan arm experienced CR/CRh at EOI as determined by IERC, compared to 41.2% of patients in the placebo arm. Post-treatment HSCT rate was 52.1% in the uproleselan arm and 51.0% in the placebo arm. Subsequent AML therapy in non-responders was 40.0% in the uproleselan arm (n=80) and 46.2% in the placebo arm (n=78). Safety Adverse events were consistent with the known safety pro backbone chemotherapy regimens. 35.9% of patients in the uproleselan arm experienced serious treatment-emergent adverse events (TEAEs) compared to 34.2% in the placebo arm. 85.9% of patients in the uproleselan arm experienced grade 3 or higher TEAEs compared to 87.6% in the placebo arm. NCI Phase 2/3 Study of Uproleselan in Frontline AML In addition to the company’s pivotal Phase 3 trial of uproleselan, the National Cancer Institute (NCI) and the Alliance for Clinical Trials in Oncology are conducting an adaptive Phase 2/3 study of uproleselan in adults with newly diagnosed AML who are 60 years or older and fit for intensive chemotherapy. Their randomized, controlled study is evaluating the addition of uproleselan to a standard cytarabine / daunorubicin regimen (7+3) versus chemotherapy alone. The Phase 2 portion of the study completed enrollment of 267 patients in December 2021. The Company is advancing discussions with the NCI and the Alliance for Clinical Trials in Oncology based on the results of the pivotal Phase 3 study of uproleselan in R/R AML.

A live webcast of the call and the corresponding slides will be available on the “Investors” tab on the GlycoMimetics website. A webcast replay will be available for 30 days following the call. About AML AML is the most common acute leukemia in adults. A cancer of the bone marrow, nearly 21,000 people in the United States are diagnosed with AML each year. Despite the availability of multiple treatments, disease prognosis is poor, and new treatment options are needed to improve outcomes. Newly diagnosed AML has the lowest 5-year survival rate of all leukemias at 31.7%. The five-year survival rate for people with relapsed/refractory disease is only 10%. About Uproleselan Discovered and developed by GlycoMimetics, uproleselan (yoo’ pro le’se lan) is an investigational, first-in-class E-selectin antagonist. GlycoMimetics has received Breakthrough Therapy and Fast Track designations from the U.S. Food and Drug Administration (FDA) and Breakthrough Therapy designation from the Chinese National Medical Products Administration for uproleselan as a potential treatment for adult AML patients with relapsed or refractory disease. E-selectin is a leukocyte adhesion molecule constitutively expressed on endothelial cells of the vasculature and bone marrow. In AML, there is evidence that E-selectin–ligand interaction between endothelial cells in the protective niche of the Bone Marrow microEnvironment (BME) and leukemic stem cells and blasts promotes leukemic cell survival and hides them from AML therapies. Uproleselan is designed to disrupt E-selectin binding and prevent leukemic myeloid cells using the protective niche of the BME. About GlycoMimetics, Inc.

GlycoMimetics Announces Results of Pivotal Phase 3 Study of Uproleselan in Relapsed/Refractory (R/R) Acute Myeloid Leukemia (AML)

Study of uproleselan combined with chemotherapy did not meet its primary endpoint of overall survival in the intent to treat population Adverse events were consistent with known side effect profiles of chemotherapy used in the study Comprehensive data analysis with medical, statistical, and regulatory experts underway and will be shared as appropriate; company will submit results for presentation at an upcoming medical meeting National Cancer Institute (NCI) Phase 2/3 study in newly diagnosed AML patients remains ongoing Conference call and webcast to be hosted today, May 6, 2024, at 8:30 a.m. ET. ROCKVILLE, Md.--(BUSINESS WIRE)-- GlycoMimetics, Inc. (Nasdaq: GLYC), a late clinical-stage biotechnology company discovering and developing glycobiology-based therapies for cancers and inflammatory diseases, today announced topline results from its Phase 3 global pivotal study of uproleselan in 388 patients with R/R AML. In the study, uproleselan combined with chemotherapy did not achieve a statistically significant improvement in overall survival in the intent to treat population versus chemotherapy alone. Patients treated with uproleselan had a median overall survival of 13 months, compared to 12.3 months in the placebo arm. Adverse events were consistent with known side effect profiles of chemotherapy used in the study. “While the outcome of our Phase 3 study in R/R AML is not what we hoped, we wish to thank the investigators, the participating patients and their families for their dedication to this large, well-controlled randomized study,” said Harout Semerjian, Chief Executive Officer of GlycoMimetics. “We are thoroughly analyzing the data in collaboration with medical, statistical and regulatory experts and are committed to submitting a comprehensive data analysis for presentation at an upcoming medical meeting.” The randomized, double-blind, placebo-controlled Phase 3 clinical study evaluated uproleselan in combination with MEC (mitoxantrone, etoposide and cytarabine) or FAI (fludarabine, cytarabine and idarubicin) in patients with R/R AML. Patients received either uproleselan or placebo for 8 days over 1 cycle of an induction and, if applicable, up to 3 cycles of consolidation. The primary endpoint of the study was overall survival without censoring for transplant. Secondary endpoints included incidence of severe oral mucositis, complete remission rate and remission rate. A total of 388 patients across 70 sites in nine countries were randomized 1:1 between treatment and placebo arms. The NCI and the Alliance for Clinical Trials in Oncology are conducting an adaptive Phase 2/3 study of uproleselan in adults with newly diagnosed AML who are 60 years or older and fit for intensive chemotherapy. The randomized, controlled study is evaluating the addition of uproleselan to a standard cytarabine/daunorubicin regimen (7+3) versus chemotherapy alone. The Phase 2 portion of the study completed enrollment of 267 patients in December 2021. Results of the pre-planned Phase 2 event free survival interim analysis will be reported when available.

About AML AML is the most common acute leukemia in adults. A cancer of the bone marrow, nearly 21,000 people in the United States are diagnosed with AML each year. Despite the availability of multiple treatments, disease prognosis is poor, and new treatment options are needed to improve outcomes. Newly diagnosed AML has the lowest 5-year survival rate of all leukemias at 31.7%. The five-year survival rate for people with relapsed/refractory disease is only 10%. About Uproleselan Discovered and developed by GlycoMimetics, uproleselan (yoo’ pro le’se lan) is an investigational, first-in-class E-selectin antagonist. GlycoMimetics has received Breakthrough Therapy and Fast Track designations from the U.S. Food and Drug Administration (FDA) and Breakthrough Therapy designation from the Chinese National Medical Products Administration for uproleselan as a potential treatment for adult AML patients with relapsed or refractory disease. E-selectin is a leukocyte adhesion molecule constitutively expressed on endothelial cells of the vasculature and bone marrow. In AML, there is evidence that E-selectin–ligand interaction between endothelial cells in the protective niche of the Bone Marrow microEnvironment (BME) and leukemic stem cells and blasts promotes leukemic cell survival and hides them from AML therapies. Uproleselan is designed to disrupt E-selectin binding and prevent leukemic myeloid cells using the protective niche of the BME. About GlycoMimetics, Inc.
