Genmab announces phase 1/2 trial results

Genmab and AbbVie have announced topline results from the first cohort of the EPCORE NHL-1 clinical trial evaluating epcoritamab (DuoBody-CD3xCD20), an investigational subcutaneous bispecific antibody.

The study cohort includes 157 patients with relapsed/refractory large B-cell lymphoma (LBCL) who received at least two prior lines of systemic therapy, including 38.9 percent who received prior treatment with chimeric antigen receptor (CAR) T-cell therapy. Based on the topline results, the companies will engage global regulatory authorities to determine next steps.

“Together with our partner, AbbVie, we will work with regulatory authorities to determine next steps and continue to evaluate epcoritamab in a variety of clinical trials as a potential treatment option for patients with various hematological malignancies,” says Jan van de Winkel, Chief Executive Officer of Genmab. “We look forward to sharing the findings at a future medical meeting.”

Broad oncology collaboration

The topline results from this cohort demonstrated an overall response rate (ORR) of 63.1 percent as confirmed by an independent review committee (IRC), which exceeded the protocol prespecified threshold for efficacy. The observed median duration of response (DOR) was 12 months. The most common treatment-emergent adverse event was cytokine release syndrome (CRS) with 49.7 percent, including 2.5 percent grade 3. The data will be submitted for presentation at a future medical meeting.

Epcoritamab is being co-developed by Genmab and AbbVie as part of the companies’ broad oncology collaboration. The companies remain committed to evaluating epcoritamab as a monotherapy, and in combination, across lines of therapy, for a variety of hematologic malignancies, including an ongoing phase 3, open-label, randomized trial evaluating epcoritamab as a monotherapy in patients with relapsed/refractory diffuse large B-cell lymphoma.
