The phase 2 CARINA study of daratumumab in non-Hodgkin lymphoma (NHL) will not proceed to stage 2, according to Genmab A/S and Janssen Biotech, Inc.
In this study, researchers have been investigating daratumumab monotherapy in patients with relapsed or refractory follicular lymphoma (FL), diffuse large B-cell lymphoma (DLBCL), or mantle cell lymphoma (MCL).
Researchers planned to enroll up to 210 patients in this trial in 2 stages. Stage 1 was designed to provide a preliminary assessment of activity.
The goal of stage 2 was to further evaluate the safety and efficacy of daratumumab in the 3 patient groups.
Stage 2 will not proceed because a data review showed the FL and DLBCL cohorts did not reach the predefined futility thresholds, which were overall response rates of 50% and 30%, respectively. In the MCL cohort, the overall response rate was not evaluable due to slow recruitment.
The decision regarding this study has no impact on other ongoing or planned studies with daratumumab.
“While we hoped that daratumumab as a monotherapy could potentially provide a new treatment option in NHL patients with a high unmet medical need, the preliminary activity profile seen was not sufficient for the study to continue,” said Jan van de Winkel, PhD, chief executive officer of Genmab.
“Daratumumab is still being investigated in a number of indications, including multiple myeloma and other hematological cancers, such as NK/T-cell lymphoma and myelodysplastic syndrome, as well as in solid tumors.”
About daratumumab
Daratumumab is a human IgG1k monoclonal antibody that binds to the CD38 molecule.
In the US, daratumumab is approved for use in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of patients with multiple myeloma who have received at least 1 prior therapy.
Daratumumab monotherapy is approved in the US for patients with multiple myeloma who have received at least 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory agent, or who are double-refractory to a proteasome inhibitor and an immunomodulatory agent.
Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license from Genmab.
