Interim Report for the First Half of 2023
Company Announcement no. 37
Epcoritamab is a proprietary bispecific antibody created using Genmab’s DuoBody technology platform.
Epcoritamab targets CD3, which is expressed on T-cells, and CD20, a clinically validated target on
malignant B-cells. Genmab used technology licensed from Medarex to generate the CD20 antibody
forming part of epcoritamab. Epcoritamab-bysp, marketed as EPKINLY, is the first U.S. FDA approved
bispecific for the treatment of adults with relapsed or refractory DLBCL, NOS, including DLBCL arising
from indolent lymphoma, and high-grade B‑cell lymphoma, after two or more lines of systemic therapy. In
2020, Genmab entered into a collaboration agreement with AbbVie to jointly develop and commercialize
epcoritamab. The companies share commercial responsibilities in the U.S. and pending approval, will
share commercial responsibilities in Japan, with AbbVie responsible for further global commercialization.
Genmab will record sales in the U.S. and Japan and receive tiered royalties on remaining global sales
outside of these territories. The companies have a broad clinical development program for epcoritamab
including three ongoing Phase 3 trials and additional trials in planning.
Please consult the U.S. Prescribing Information
for EPKINLY for the labeled indication and safety
information, including the boxed warning.
Second Quarter 2023 Updates
• June: Genmab and AbbVie announced topline results from the FL cohort of the Phase 1/2
EPCORE NHL-1 clinical trial evaluating epcoritamab in patients with relapsed/refractory FL who
received at least two prior lines of systemic therapy. 70.3% of patients were double refractory to
an anti-CD20 monoclonal antibody and an alkylating agent. Based on the topline results, the
companies will engage with global regulatory authorities to determine next steps. The topline
results from this cohort showed an overall response rate (ORR) of 82% as confirmed by an
independent review committee (IRC), which exceeded the protocol prespecified threshold for
efficacy. The observed median duration of response (DOR) was not reached. No new safety
signals were observed with epcoritamab in this study at the time of analysis. The most common
treatment-emergent adverse event was cytokine release syndrome (CRS) with 66.4% (1.6%
grade >2). Aligned with the U.S. FDA Project Optimus, the optimization part of the trial is
continuing to evaluate alternative step-up dosing regimens to mitigate the risk of CRS; preliminary
data on the initial patients enrolled indicate a clinically meaningful improvement in CRS rate. The
results from this cohort, along with the results from the optimization part of the trial, will be
submitted for presentation at an upcoming medical congress.
• June: Epcoritamab was added to the National Comprehensive Cancer Network
®
(NCCN
®
) Clinical
Practice Guidelines in Oncology (NCCN Guidelines
®
) for “B-cell Lymphomas” (Version 4.2023)
for third-line and subsequent therapy for patients with DLBCL, including patients with disease
progression after transplant or chimeric antigen receptor (CAR-T) cell therapy and as a Category
2A, preferred regimen for patients with histologic transformation of indolent lymphomas to DLBCL
and no intention to proceed to transplant, including patients with disease progression after
transplant or CAR-T cell therapy.
• June: Multiple data presentations were featured at the 2023 American Society of Clinical
Oncology (ASCO) Annual Meeting and the 2023 European Hematology Association (EHA)
Congress. These included an oral presentation at both congresses on data from the Phase 1/2
EPCORE NHL-2 (NCT04663347) trial of epcoritamab in combination with rituximab and
lenalidomide for patients with high-risk FL and poster presentations highlighting epcoritamab in
lymphoma across multiple lines of therapy and histologies.
• May: The U.S. FDA granted accelerated approval for EPKINLY as noted above.
