ROCKVILLE, Md., March 07, 2024 (GLOBE NEWSWIRE) -- MacroGenics, Inc.  (NASDAQ: MGNX), a biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today provided an update on its recent corporate progress and reported financial results for the year ended December 31, 2023.

“We expect that 2024 will be an important year for MacroGenics, with multiple pipeline advancements anticipated," said Scott Koenig, M.D., Ph.D., President and CEO of MacroGenics. “Late last year, we completed enrollment of 177 patients in the TAMARACK Phase 2 study of vobra duo, which was ahead of schedule. We plan to present the initial TAMARACK clinical data in the second quarter of this year. Later in the year, we expect to share updated clinical data from the trial. In addition, we continue to enroll the LORIKEET Phase 2 study of lorigerlimab in mCRPC and expect to start enrolling patients in the dose expansion portion of the combination study of vobra duo and lorigerlimab. Finally, we are excited about the potential of our topoisomerase I inhibitor-based ADCs, including MGC026, for which we recently began a Phase 1 study, and MGC028, for which we anticipate submitting an IND by year end.”

Updates on Proprietary Investigational Programs

Recent progress and anticipated events related to MacroGenics’ investigational product candidates are highlighted below.

  • Vobramitamab duocarmazine (vobra duo) is an antibody-drug conjugate (ADC) that targets B7-H3, an antigen with broad expression across multiple solid tumors and a member of the B7 family of molecules involved in immune regulation.
    • MacroGenics completed enrollment of the TAMARACK Phase 2 study of vobra duo in November 2023. A total of 177 patients have been dosed in the study, exceeding the study design goal of 100 participants. TAMARACK is being conducted in patients with metastatic castration-resistant prostate cancer (mCRPC) who were previously treated with one prior androgen receptor axis-targeted therapy (ARAT). Participants may have received up to one prior taxane-containing regimen, but no other chemotherapy agents. The TAMARACK study is designed to evaluate vobra duo at two different doses: 2.0 mg/kg or 2.7 mg/kg every four weeks (q4W).

      In late January 2024, the TAMARACK independent data safety monitoring committee (IDSMC) recommended continuing the study. Also, in early February, MacroGenics submitted an abstract to the American Society of Clinical Oncology Annual Meeting (ASCO) that included the safety data reviewed by the IDSMC, based on a January 2024 data cut-off. The Company anticipates presenting updated safety and preliminary efficacy data at ASCO.
    • MacroGenics intends to expand the TAMARACK study of vobra duo by enrolling patients with non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), melanoma, squamous cell carcinoma of the head and neck (SCCHN) and anal cancer. The Company expects to initiate dosing in these additional cohorts in mid-2024.
    • MacroGenics continues to enroll a Phase 1/2 dose escalation study of vobra duo in combination with lorigerlimab in patients with various advanced solid tumors. The Company anticipates commencing a dose expansion study of this combination in mCRPC and at least one additional indication in 2024.
  • Lorigerlimab is a bispecific, tetravalent PD-1 × CTLA-4 DART® molecule. MacroGenics is enrolling LORIKEET, a randomized Phase 2 study of lorigerlimab in combination with docetaxel vs. docetaxel alone in second-line, chemotherapy-naïve mCRPC patients. A total of 150 patients are planned to be treated in the 2:1 randomized study. The current trial design includes a primary study endpoint of radiographic progression-free survival (rPFS). The Company anticipates providing a study update in the second half of 2024.
  • MGD024 is a next-generation, humanized CD123 × CD3 DART molecule designed to minimize cytokine-release syndrome, while maintaining anti-tumor cytolytic activity, and permitting intermittent dosing through a longer half-life. MacroGenics continues to enroll patients in a Phase 1 dose-escalation study of MGD024 in patients with CD123-positive neoplasms, including acute myeloid leukemia and myelodysplastic syndromes.
  • MGC026 is a clinical ADC directed against B7-H3, incorporating a novel site-specific linker and topoisomerase I inhibitor-based cytotoxic payload developed by Synaffix (a Lonza company). With distinct mechanisms of action, vobra duo and MGC026 may address different cancers, tumor stages, or be used in combination with alternate agents — or potentially with one another — to enhance their clinical utility. The Company plans to present MGC026 preclinical data at the upcoming American Association for Cancer Research (AACR) Annual Meeting in April 2024. MacroGenics recently initiated a Phase 1 dose escalation study of MGC026 in patients with advanced solid tumors.
  • MGC028 is a preclinical ADC incorporating an ADAM9-targeting antibody and represents the second MacroGenics ADC molecule that incorporates Synaffix’s novel site-specific linker and topoisomerase I inhibitor-based cytotoxic payload. ADAM9 (a disintegrin and metalloprotease domain 9) is a member of the ADAM family of multifunctional type 1 transmembrane proteins that play a role in tumorigenesis and cancer progression and is overexpressed in multiple cancers, making it an attractive target for cancer treatment. MacroGenics plans to present preclinical data for MGC028 at the upcoming AACR Annual Meeting in April and currently anticipates submitting an investigational new drug (IND) application for MGC028 by the end of 2024.

    MGC028 is the second ADAM9-targeted ADC that MacroGenics has pursued. The first was IMGC936, a molecule with a maytansinoid payload that was advanced under a co-development arrangement with ImmunoGen, Inc. (ImmunoGen, now part of AbbVie). Under the 50/50 collaboration, ImmunoGen led clinical development and completed initial Phase 1 dose escalation and dose expansion studies. Neither MacroGenics nor AbbVie intends to further pursue development of IMGC936 as the molecule did not achieve pre-established clinical safety and efficacy benchmarks. The Company believes ADAM9 remains a promising target for delivery of an alternative cytotoxic payload.
  • Enoblituzumab is an Fc-optimized monoclonal antibody that targets B7-H3. MacroGenics’ academic collaborators have initiated the HEAT study, an investigator-sponsored, randomized Phase 2 clinical trial. This study will evaluate the activity of neoadjuvant enoblituzumab given prior to radical prostatectomy in up to 219 men with high-risk localized prostate cancer.

2023 Financial Results

  • Cash Position: Cash, cash equivalents and marketable securities balance as of December 31, 2023, was $229.8 million, compared to $154.3 million as of December 31, 2022.
  • Revenue: Total revenue was $58.7 million for the year ended December 31, 2023, compared to total revenue of $151.9 million for the year ended December 31, 2022. The decrease was primarily due to a decrease in revenue from collaborative and other agreements.
  • R&D Expenses: Research and development expenses were $166.6 million for the year ended December 31, 2023, compared to $207.0 million for the year ended December 31, 2022. The decrease was primarily due to decreased manufacturing-related costs for vobra duo, decreased development and clinical trial costs related to margetuximab, and decreased costs related to discontinued studies, partially offset by increased expenses related to MGC026 and MGC028 development.
  • SG&A Expenses: Selling, general and administrative expenses were $52.2 million for the year ended December 31, 2023, compared to $58.9 million for the year ended December 31, 2022. The decrease was primarily related to decreased selling costs for MARGENZA®.
  • Other Income: During the year ended December 31, 2023, MacroGenics received $100.0 million proceeds from the sale of its single-digit royalty interest on global net sales of TZIELD® to DRI Healthcare Acquisitions LP. In addition, the Company received a $50.0 million milestone payment from Sanofi S.A. related to the achievement of a primary endpoint in a TZIELD clinical study. Under GAAP guidelines and pursuant to Financial Accounting Standards Board’s Accounting Standards Codification 470, this combined $150.0 million was included in Other Income as a “Gain on royalty monetization arrangement” in 2023.
  • Net Loss: Net loss was $9.1 million for the year ended December 31, 2023, compared to net loss of $119.8 million for the year ended December 31, 2022.
  • Shares Outstanding: Shares of common stock outstanding as of December 31, 2023 were 62,070,627.
  • Cash Runway Guidance: MacroGenics anticipates that its cash, cash equivalents and marketable securities balance of $229.8 million as of December 31, 2023, in addition to projected and anticipated future payments from partners and product revenues should extend its cash runway into 2026. The Company’s expected funding requirements reflect anticipated expenditures related to the Phase 2 TAMARACK clinical trial, the Phase 2 LORIKEET study as well as MacroGenics’ other ongoing clinical and preclinical studies.
