IMGN632 is a CD123-targeting ADC in Phase I testing for hematological malignancies, including acute myeloid leukemia (AML), blastic plasmacytoid dendritic cell neoplasm (BPDCN), and acute lymphocytic leukemia (ALL). IMGN632 uses one of ImmunoGen’s novel indolino-benzodiazepine (IGN) payloads, which alkylate DNA without crosslinking. IGNs have been designed to have high potency against AML blasts, while demonstrating less toxicity to normal marrow progenitors than other DNA-targeting payloads.

Updated safety and efficacy findings from the dose escalation and expansion of the first-in-human trial of IMGN632 in patients with relapsed/refractory AML and BPDCN will be reported in an oral presentation. Preclinical data related to IMGN632 in combination with Vidaza (azacitidine) and Venclexta (venetoclax) and two "trial in progress" posters will also be presented in poster sessions.

"Building on initial data shared at ASH (Free ASH Whitepaper) last year, we continue to be encouraged by the anti-leukemia activity and tolerability of IMGN632 in AML and BPCDN," said Anna Berkenblit, MD, Senior Vice President and Chief Medical Officer of ImmunoGen. "These data support the continued development of IMGN632 as a monotherapy for BPDCN and MRD+ AML, and in combinations for AML. Despite recent advances, including the first drug approved for BPDCN and approvals of targeted therapies for molecularly-defined subsets of AML, the need remains for well-tolerated, effective, and convenient therapies in these diseases."

ORAL PRESENTATION DETAILS
Oral Session 613: Monday, December 9, 2019, 3:00pm EST
Title (Abstract #734): "Clinical Profile of IMGN632, a Novel CD123-Targeting Antibody-Drug Conjugate, in Patients with Relapsed/Refractory Acute Myeloid Leukemia or Blastic Plasmacytoid Dendritic Cell Neoplasm"

Initial key findings include:

Safety

IMGN632 was administered to 74 patients over dose levels ranging from 0.015 to 0.45 mg/kg intravenously on the every 3 week schedule and 0.015-0.06 mg/kg on the fractionated day 1, 4, and 8 schedule every 3 weeks.
IMGN632 displays a tolerable safety profile and activity at doses up to 0.3 mg/kg.
The most common treatment-related adverse event was infusion-related reactions (16%; four grade 3); none required treatment discontinuation.
Single dose-limiting toxicities were seen at the three highest dose levels tested: one prolonged neutropenia and two reversible cases of veno-occlusive disease; no patterns of hepatotoxicity or cytopenias occurred with doses below 0.18 mg/kg.
Although no maximum tolerated dose was determined on either schedule, based on the efficacy, safety, and pharmacokinetic data generated, the dose and schedule of 0.045 mg/kg given on day 1 every 3 weeks has been selected for Phase 2 development.
AML Efficacy

In the assessable AML population (n=66), 37 (55%) had a reduction in bone marrow blasts and 13 (20%) achieved an objective response across all dose levels and both schedules achieved an objective response, including three complete remissions (CR) and eight CRs with incomplete recovery (CRi) in heavily pretreated patients. The majority of responders (77%) had failed prior intensive therapies, including three with prior transplant, 62% had an adverse risk classification, and 23% were primary refractory.
A 32% response rate (6/19 patients; two CR, three CRi, and one morphologic leukemia free state) was seen in primary AML patients treated with dose and schedule selected for Phase 2 development.
BPDCN Efficacy

Three of seven evaluable BPDCN patients (43%) achieved a response after a single dose of IMGN632, one CR, one CRi, and one partial remission; all three patients had received prior SL-401 (tagraxofusp-erzs; Elzonris).

ABOUT ACUTE MYELOID LEUKEMIA (AML)
AML is a cancer of the bone marrow cells that produce white blood cells. It causes the marrow to increasingly generate abnormal, immature white blood cells (blasts) that do not mature into effective infection-fighting cells. The blasts quickly fill the bone marrow, impacting the production of normal platelets and red blood cells. The resulting deficiencies in normal blood cells leave the patient vulnerable to infections, bleeding problems, and anemia. It is estimated that, in the U.S. alone, 21,380 patients will be diagnosed with AML this year and 10,590 patients will die from the disease.

ABOUT BLASTIC PLASMACYTOID DENDRITIC CELL NEOPLASM (BPDCN)
BPDCN is a rare form of blood cancer that has features of both leukemia and lymphoma, with characteristic skin lesions, lymph node involvement, and frequent spread to the bone marrow. This aggressive cancer requires intense treatment often followed by stem cell transplant. Despite the recent approval of a CD123-targeting therapy, the unmet need remains high in the relapsed/refractory setting.

ABOUT CD123
CD123, the interleukin-3 alpha chain, is expressed on multiple myeloid and lymphoid cancers including AML, BPDCN, ALL, chronic myeloid leukemia, and myeloproliferative neoplasms. With limited expression on normal hematopoietic cells, rapid internalization, and expression on AML leukemia stem cells, CD123 is a validated therapeutic target, with the recent approval of a CD123-targeting therapy for BPDCN.

On November 6, 2019 Idera Pharmaceuticals, Inc. ("Idera") (NASDAQ: IDRA), a clinical-stage biopharmaceutical company focused on the development, and ultimately the commercialization, of therapeutic drug candidates for both oncology and rare disease indications, reported its operational and financial results for the third quarter ended September 30, 2019 (Press release, Idera Pharmaceuticals, NOV 6, 2019, View Source [SID1234550471]).

"Our third-quarter performance underscores the strength of our commercial and R&D organizations," said Timothy Walbert, chairman, president and chief executive officer, Horizon. "We generated record quarterly net sales in our orphan and rheumatology segment – including a record quarter for net sales of KRYSTEXXA, our medicine for uncontrolled gout – and the U.S. FDA also granted Priority Review of our BLA for teprotumumab, our biologic candidate for the treatment of active thyroid eye disease. We made great progress on all fronts during the quarter, including our market education activities related to teprotumumab, and remain excited about the prospect of being able to address the significant unmet need for patients living with active thyroid eye disease."

Financial Highlights

Third-Quarter and Recent Company Highlights

Granted Priority Review of Teprotumumab BLA: In September, the Company announced the U.S. Food and Drug Administration (FDA) accepted the Biologics License Application (BLA) for its investigational medicine teprotumumab for the treatment of active TED and granted it Priority Review designation, with a March 8, 2020, Prescription Drug User Fee Act (PDUFA) date. If approved, teprotumumab would be the first and only approved treatment for active TED.

Presented Additional Teprotumumab Phase 3 Data: The Company recently presented additional data from the Phase 3 OPTIC confirmatory clinical trial showing that teprotumumab provided significant benefit on several devastating effects of active TED compared with placebo, including diplopia (double vision), quality of life (QoL) and clinical activity score (CAS). At Week 24, 68 percent of teprotumumab patients had a change from baseline of at least 1 grade in diplopia, compared to 29 percent of placebo patients (p=0.001). On the Graves’ Ophthalmopathy Quality of Life (GO-QoL) scale, a change of 6 points is considered clinically significant, and teprotumumab patients had a mean change of 13.79 compared to 4.43 for placebo patients (p<0.001). At Week 24, 59 percent of teprotumumab patients achieved a CAS value of 0 or 1 compared to 21 percent of placebo patients (p<0.001). These data were presented during the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) 50th Anniversary 2019 Fall Scientific Symposium in San Francisco, and build upon data presented earlier in the year that demonstrated the significant benefit of teprotumumab on proptosis.

Announced Teprotumumab Expanded Access Program (EAP): In August, the Company announced an EAP for teprotumumab while the FDA reviews the BLA. The EAP provides access to teprotumumab for patients with active TED who meet protocol criteria, who may have otherwise progressed to the inactive stage of the debilitating disease before the BLA review process is completed.

Initiated PROTECT Trial Evaluating KRYSTEXXA to Improve Management of Uncontrolled Gout for Adults with a Kidney Transplant: In October, the Company initiated its open-label PROTECT clinical trial evaluating the use of KRYSTEXXA in adults with uncontrolled gout who have undergone a kidney transplant. The objective of the trial is to demonstrate that KRYSTEXXA provides effective disease control without burdening the kidneys. The randomized multicenter open-label trial is expected to enroll 20 adults with uncontrolled gout who have received a kidney transplant.

Further Improved the Company’s Capital Structure: In July, the Company issued $600 million of 5.5 percent Senior Notes due 2027 and used the proceeds together with cash on hand to repay $625 million of its outstanding debt. These actions reduced interest expense and extended the maturity of the debt, furthering the Company’s strategy to improve its capital structure. The Company has reduced its gross debt by $575 million in the year-to-date period ended Sept. 30, 2019.

Intellectual Property Update: In October, the Federal Circuit Court of Appeals issued a decision in favor of the Company regarding an appeal of the 2017 decision by the United States District Court for the District of New Jersey upholding the validity of a PENNSAID 2% patent that expires in 2027.

Gender and Ethnicity Pay Equity Demonstrated; Received Best Medium Workplace Award: A recent study conducted by Aon, a leading compensation consulting firm, showed that Horizon demonstrates both gender and ethnicity pay equity, ranking in the top five of the roughly 100 companies Aon has studied in this regard, and in line with the value the Company places on diversity. In addition, the Company was selected to FORTUNE Magazine’s 2019 "Best Medium Workplaces" list for the fourth consecutive year, ranking eighth out of 100 other medium sized companies.

Appointed Sue Mahony to the Board of Directors: In August, the Company appointed Sue Mahony, Ph.D., MBA, to its board of directors. Dr. Mahony brings more than 30 years of diverse industry experience to the board, including an 18-year tenure at Eli Lilly and Company, where she served in a variety of global and domestic leadership roles of increasing responsibility, including helping oversee the development of an innovative pipeline. Before Lilly, Dr. Mahony spent five years at Bristol-Myers Squibb Company.

Named Andy Pasternak Executive Vice President, Chief Business Officer: In August, the Company named Andy Pasternak executive vice president, chief business officer, effective Nov. 1. Pasternak leads business development, mergers and acquisitions, corporate strategy, commercial development and portfolio management.

Research and Development Programs

Orphan Disease Candidate and Program:

Teprotumumab: Teprotumumab is a fully human monoclonal antibody insulin-like growth factor-1 receptor (IGF-1R) inhibitor candidate for the treatment of active TED. TED is a serious, progressive, vision-threatening autoimmune disease in which the muscles and fatty tissue behind the eye become inflamed and expand, which can lead to proptosis (eye bulging) and diplopia (double vision) and impact activities of daily living and quality of life. The development program for teprotumumab in TED includes positive results from the confirmatory Phase 3 OPTIC clinical trial, announced in February 2019, as well as positive Phase 2 results published in The New England Journal of Medicine in May 2017. The OPTIC study met its primary endpoint of a ³2 mm reduction in proptosis (p<0.001), the main cause of morbidity in TED, with 82.9 percent of patients treated with teprotumumab demonstrating a significant improvement in proptosis compared to 9.5 percent of placebo patients. In addition, all secondary endpoints were met (p£0.001), and the safety profile was consistent with the Phase 2 study.

Rheumatology Pipeline Candidates and Programs:

KRYSTEXXA MIRROR Immunomodulation Trial: The Company is evaluating the use of methotrexate to increase the response rate with KRYSTEXXA. This evaluation was initiated through the small open-label MIRROR pilot study, followed by the larger MIRROR registrational clinical trial. Methotrexate is the immunomodulator most used by rheumatologists, and has been shown to reduce anti-drug antibody formation to biologic therapies when used in conjunction with these therapies. The MIRROR registrational trial commenced in June.

On November 6, 2019 Harpoon Therapeutics, Inc. (Nasdaq: HARP), a clinical-stage immunotherapy company developing a novel class of T cell engagers, reported financial results for the third quarter and nine months ended September 30, 2019 and provided a corporate update (Press release, Harpoon Therapeutics, NOV 6, 2019, View Source [SID1234550469]).

"During the third quarter we made significant strides in the advancement of our novel T cell engagers, as we continue to advance our two clinical stage programs," said Gerald McMahon, Ph.D., President and Chief Executive Officer of Harpoon Therapeutics. "We are also excited by the progress of our two preclinical TriTAC programs, highlighted by the encouraging HPN328 data we recently presented at a medical meeting which further exemplifies the platform. We expect to present clinical data from both our HPN424 and HPN536 programs next year."

Third Quarter 2019 Business Highlights and Other Recent Developments

In October, Harpoon presented data on HPN328 for the treatment of small cell lung cancer at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) in Boston. The presentation demonstrated that HPN328 has the potential to be an efficacious, safe, and convenient therapeutic for patients with DLL3-expressing malignancies. HPN328 was well-tolerated in cynomolgus monkeys at 1 and 10 mg/kg and pharmacokinetic data support the potential for once weekly dosing.

Patient enrollment and dose escalation continues in Phase 1 trial for HPN424 and Phase 1/2a trial for HPN536. Harpoon plans to present interim HPN424 results at a medical meeting in the first half of 2020 and plans to present proof of concept data for HPN536 in 2020.

Anticipated Milestones

HPN424 – present interim Phase 1 data in the first half of 2020 at a medical conference and initiate expansion cohort in 2020

HPN536 – present proof of concept data in 2020

HPN217 – submit IND by the end of 2019 and initiate Phase 1/2 trial in the first half of 2020

HPN328 – initiate Phase 1 trial in 2020

Third Quarter and Year-to-Date Financial Results

Harpoon Therapeutics ended the third quarter of 2019 with $121.2 million in cash, cash equivalents, and marketable securities compared to $89.5 million as of December 31, 2018. The increase was due to approximately $70.7 million in net proceeds from Harpoon’s initial public offering, completed in February 2019, partially offset by cash used in operations.

Net loss for the third quarter ended September 30, 2019 was $15.9 million compared to $6.8 million for the third quarter ended September 30, 2018. The net loss for the nine months ended September 30, 2019 was $41.3 million compared to $17.6 million in the first nine months of the prior year.

Revenue for the third quarter of 2019 was $1.4 million compared to $1.1 million for the third quarter of 2018. For the nine months ended September 30, 2019, revenue was $3.5 million compared to $3.7 million for the nine months ended September 30, 2018. For the three months ended September 30, 2019, the increase was due to an increase in the recognized portion of the deferred $17.0 million upfront payment received by the company in October 2017 under the collaboration agreement with AbbVie. For the nine months ended September 30, 2019, the decrease was due to an upfront payment of $0.5 million recognized in the first quarter of 2018 related to the license agreement with Werewolf Therapeutics, Inc., offset by a $0.3 million increase in the portion of the upfront payment under the collaboration agreement with AbbVie recognized for the quarter ended September 30, 2019. During both the three and nine month periods, revenue primarily consisted of the recognized portion of the deferred $17.0 million upfront payment under the collaboration agreement with AbbVie.

Research and development (R&D) expense for the third quarter of 2019 was $9.5 million compared to $5.9 million for the third quarter of 2018. For the nine months ended September 30, 2019, R&D expense was $28.9 million, compared to $17.7 million for the nine months ended September 30, 2018. The increase for both periods primarily arose from clinical development expenses and an increase in personnel-related expenses, which included conducting preclinical studies, the continuation of the clinical trials for HPN424 and HPN536, and manufacturing activities for four TriTAC product candidates in various stages of development.

General and administrative (G&A) expense for the third quarter of 2019 was $8.5 million compared to $1.9 million for the third quarter of 2018. G&A expense for the nine months ended September 30, 2019 was $18.1 million compared to $3.9 million for the nine months ended September 30, 2018. The increase for both periods was due to higher expenses primarily related to legal fees associated with ongoing Maverick litigation, consulting and accounting services, an increase in headcount, and other professional services to support our ongoing operations as a public company.

On November 6, 2019 GlycoMimetics, Inc. (Nasdaq: GLYC) reported that seven abstracts covering data from the company’s research and clinical portfolio have been accepted for presentation at the 61st American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition, to be held December 7-10, 2019 in Orlando (Press release, GlycoMimetics, NOV 6, 2019, View Source [SID1234550468]).

Of particular note, clinical data from the Company’s recent Phase 1/2 study of uproleselan, an E-selectin antagonist and the company’s lead wholly owned clinical candidate, were selected for a poster presentation on Sunday, December 8 during a session on biology of AML. The presentation will feature data showing uproleselan’s ability to reverse chemoresistance in patients who have high-risk clinical features and over-express the E-selectin ligand. The poster presentation will highlight the potential benefits of this novel candidate, which resulted in an overall survival of 12.7 months in a high-risk group of patients when added to salvage chemotherapy – longer than expected survival based on clinical variables alone.

A poster presentation of complementary work by investigators at the Fred Hutchinson Cancer Research Center will highlight research identifying the unique gene expression signature that is a surrogate for E-selectin ligand expression on leukemic cells. For the first time, in a large clinical database, independent analysis of glycogene signature demonstrated that E-selectin ligand expression is associated with poor survival in pediatric patients with AML.

"The collective data from this year’s posters and presentations support the fact that E-selectin plays a major role in chemoresistance in AML, and we are excited to share results showing that uproleselan can counter resistance by augmenting deep clinical responses – and ultimately may prolong survival," said GlycoMimetics Senior Vice President of Clinical Development and Chief Medical Officer Helen Thackray, M.D., FAAP. "As a pioneer in the field of environment-mediated drug resistance in oncology, the GlycoMimetics team is applying its proprietary technology to discover and develop drugs that target these pathways. In addition, we are actively studying key related biomarkers in multiple cancers and exploring additional ways to incorporate these recent discoveries into our development program."

Other GlycoMimetics presentations will showcase research on how the E-selectin binding potential of AML blasts is altered during therapy and how these variations influence treatment outcomes, as well as investigations into which AML cell surface receptors mediate E-selectin induced chemo-resistance.

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.
