Company Description
Genmab A/S (NASDAQ: GMAB) is an international biotechnology company focused on developing antibody-based medicines for cancer and other serious diseases. Classified under pharmaceutical preparation manufacturing within the broader manufacturing sector, Genmab centers its work on antibody therapeutics and related technologies. The company is headquartered in Copenhagen, Denmark, and was established in 1999. According to company announcements, Genmab has an international presence across North America, Europe and Asia Pacific.
Genmab describes its core purpose as striving to improve the lives of patients through antibody medicines. Over more than 25 years, its teams have advanced a broad range of antibody-based therapeutic formats, including bispecific antibodies, antibody–drug conjugates (ADCs), immune‑modulating antibodies and other next‑generation modalities. The company’s science powers eight approved antibody medicines, and it is advancing a late‑stage clinical pipeline that includes wholly owned programs.
Antibody Technology Platforms and Therapeutic Focus
Genmab has invented and developed several proprietary antibody technology platforms. These include DuoBody, HexaBody, DuoHexaBody and HexElect, which are referenced in company disclosures as Genmab trademarks. The company also refers to its work on bispecific T‑cell engagers, next‑generation immune checkpoint modulators and effector function‑enhanced antibodies. These platforms underpin both Genmab’s internal pipeline and collaborations with partners.
One important example is epcoritamab, an IgG1‑bispecific antibody created using Genmab’s DuoBody technology and administered subcutaneously. Epcoritamab is designed to bind to CD3 on T cells and CD20 on B cells and to induce T‑cell‑mediated killing of CD20+ cells. It has received regulatory approvals in certain lymphoma indications in several territories under the brand names EPKINLY and TEPKINLY. Epcoritamab is being co‑developed with AbbVie, with shared commercial responsibilities in the U.S. and Japan and AbbVie responsible for further global commercialization.
Genmab’s science also supports other antibody medicines developed with partners. A notable example is Darzalex (daratumumab), created in partnership with Johnson & Johnson and described in third‑party data as Genmab’s leading product for multiple myeloma. Other partnered medicines mentioned in available descriptions include Tepezza for thyroid eye disease, Kesimpta for relapsing multiple sclerosis, Rybrevant for non‑small cell lung cancer, Tivdak for cervical cancer and Epkinly/Epcoritamab for diffuse large B‑cell lymphoma and follicular lymphoma, reflecting Genmab’s focus on oncology and serious immune‑related conditions.
Late‑Stage Pipeline and Key Programs
Company announcements emphasize a strong late‑stage pipeline, including both partnered and wholly owned programs. Genmab highlights several late‑stage investigational antibody medicines across solid tumors and hematological malignancies. Among these are:
- EPKINLY (epcoritamab‑bysp), a T‑cell engaging bispecific antibody for B‑cell malignancies, including diffuse large B‑cell lymphoma (DLBCL) and follicular lymphoma (FL). Epcoritamab is being evaluated as monotherapy and in combination with standard regimens such as R‑CHOP, R‑mini‑CHOP, rituximab and lenalidomide (R2), and bendamustine plus rituximab (BR) in multiple Phase 1b/2 and Phase 3 trials.
- Rinatabart sesutecan (Rina‑S), an investigational FRα‑targeted ADC described as wholly owned by Genmab (with a related trademark arrangement). It is being studied in advanced endometrial cancer and other gynecologic cancers, with updated Phase 1/2 data in heavily pretreated endometrial cancer and ongoing Phase 3 trials.
- Petosemtamab, a late‑stage EGFRxLGR5 bispecific antibody for head and neck cancer, added to Genmab’s portfolio through the acquisition of Merus N.V. Genmab states that this asset has two Breakthrough Therapy Designations and is in Phase 3 development.
- Epcoritamab programs across B‑cell non‑Hodgkin lymphoma subtypes, including DLBCL, FL, small lymphocytic lymphoma and Richter transformation, in both first‑line and relapsed/refractory settings.
Genmab’s portfolio prioritization updates show that the company periodically reviews its pipeline to focus on what it calls the most value‑creating late‑stage opportunities. For example, it has announced the discontinuation of clinical development of acasunlimab in order to concentrate resources on programs such as EPKINLY, petosemtamab and Rina‑S.
Business Model and Collaborations
Genmab’s business model, as reflected in public descriptions and company announcements, combines proprietary drug development with extensive partnerships. The company’s antibody platforms and know‑how support collaborations with large biopharmaceutical companies. Epcoritamab is co‑developed and co‑commercialized with AbbVie. Darzalex and Rybrevant are associated with Johnson & Johnson, while Tivdak has been developed with Seagen. Other medicines mentioned in third‑party descriptions, such as Tepezza and Kesimpta, involve partners including Horizon and Novartis.
Genmab also pursues corporate transactions to expand its pipeline and shift toward a greater proportion of wholly owned assets. The announced acquisition of Merus N.V. is described by Genmab as accelerating its move to a wholly owned model and diversifying revenue sources. The company has also disclosed a tender offer structure and related financing plans for this transaction in its communications and SEC filings.
Use of Data, Digital and AI Capabilities
Company announcements highlight Genmab’s use of translational, quantitative and data sciences to support its pipeline. In addition, Genmab has announced a partnership with Anthropic to design and deploy custom Claude‑powered agentic AI solutions. According to the announcement, these AI tools are intended to support Genmab’s clinical development priorities by accelerating data processing, analysis and document generation within defined guardrails and with human oversight. The company frames this as part of its ambition to build an AI‑enabled innovation model and to create a more scalable and digitally enabled R&D engine.
Geographic Footprint and Corporate Structure
Genmab is headquartered in Copenhagen, Denmark, and describes itself as having an international presence across North America, Europe and Asia Pacific. As a foreign private issuer listed on Nasdaq, Genmab files annual reports on Form 20‑F and furnishes current reports on Form 6‑K with the U.S. Securities and Exchange Commission. Recent 6‑K filings include interim reports, capital increases from employee warrant exercises, grants of restricted stock units and warrants, articles of association updates and company announcements related to product data and corporate transactions.
Regulatory and Clinical Focus Areas
Genmab’s public communications emphasize several therapeutic focus areas:
- Hematologic malignancies: DLBCL, FL and other B‑cell non‑Hodgkin lymphomas, including Richter transformation, where epcoritamab is being studied as monotherapy and in combination regimens.
- Solid tumors: Head and neck cancer through petosemtamab, and gynecologic cancers such as endometrial and ovarian cancer through Rina‑S.
- Other serious diseases: Through partnered antibody medicines such as Darzalex, Tepezza, Kesimpta, Rybrevant and Tivdak, which address multiple myeloma, thyroid eye disease, multiple sclerosis, lung cancer and cervical cancer, respectively, as stated in third‑party descriptions.
Genmab’s announcements frequently reference Breakthrough Therapy Designations granted by the U.S. Food and Drug Administration for certain assets (for example, petosemtamab and Rina‑S) and regulatory approvals for epcoritamab in lymphoma indications across multiple countries.
Strategic Vision
Genmab articulates a long‑term vision to transform the lives of people with cancer and other serious diseases with what it calls “knock‑your‑socks‑off (KYSO) antibody medicines.” The company positions its antibody technology platforms, late‑stage pipeline, global collaborations and AI‑enabled R&D capabilities as central elements in pursuing this vision.
