MorphoSys Presents Primary Analysis Data from L-MIND Study of Tafasitamab (MOR208) in combination with Lenalidomide in r/r DLBCL at ICML 2019
MorphoSys AG (FSE: MOR; Prime Standard Segment; MDAX & TecDAX; Nasdaq: MOR) today presented data from the primary analysis (cut-off date November 30, 2018) of the ongoing single-arm phase 2 clinical trial known as L-MIND in an oral presentation at the 15th International Conference on Malignant Lymphoma (ICML) in Lugano, Switzerland.
The L-MIND study enrolled patients with relapsed or refractory diffuse large B cell lymphoma (r/r DLBCL), who are ineligible for high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT). The primary analysis data reported today included 80 patients enrolled into the trial who had received tafasitamab and lenalidomide and had been followed-up as per protocol for at least one year. Efficacy results in this update are based on response rates assessed by an independent review committee for all 80 patients. Patients enrolled had a median age of 72 years and had received a median of two prior treatment lines.
The primary endpoint, defined as best objective response rate (ORR) compared to published data on the respective monotherapies, has been met. The ORR was 60% (48 out of 80 patients), and the complete response (CR) rate was 43% (34 out of 80 patients). 82% of the CRs were PET (positron emission tomography)-confirmed. The median progression-free survival (mPFS) was 12.1 months with a median follow-up of 17.3 months. Responses were durable with a median duration of response (mDoR) of 21.7 months. Median overall survival (mOS) was not reached (NR) (95% CI 18.3 months - NR) with a median follow-up time of 19.6 months. The 12-month OS rate was 73.3%.
Efficacy parameters, such as response rates, showed comparable results in most patient subgroups of interest, including rituximab refractory versus non-refractory and primary refractory versus non-primary refractory, amongst others.
The L-MIND treatment combination was generally well tolerated in this study; infusion-related reactions (IRRs) for tafasitamab were reported for only 6% of the patients and were limited to grade 1. The most frequent treatment-emergent adverse events (TEAEs) with a toxicity grading of 3 or higher were neutropenia in 48%, thrombocytopenia in 17%, and anemia in 7% patients each. Treatment-related serious adverse events (SAEs) occurred in 15 (18.5%) patients, the majority of which were infections or neutropenic fever. 37 (43%) patients required dose reduction with lenalidomide, 62 patients (78%) could stay on a daily lenalidomide dose of 20 mg or higher.
"We are very pleased by the results from the primary analysis of the L-MIND study and are especially encouraged by the durability of the responses and the OS that we are seeing", commented Dr. Malte Peters, Chief Development Officer of MorphoSys AG. "If approved, we believe that with tafasitamab in combination with lenalidomide we can offer a chemo-free treatment option to patients with r/r DLBCL who are ineligible for HDC and ASCT. We remain highly committed to completing the submission of a BLA to the FDA by end of this year."
"The results from the L-MIND study presented today at the ICML meeting in Lugano are very encouraging. We are particularly pleased to see such a high complete response rate and a prolonged response duration, which is unusual in this population of relapsed or refractory DLBCL. The number of patients on this study with a complete remission was 43%; the probability that these patients remain in remission 21 months after they started treatment was 93% based on Kaplan Meier analysis of DoR", commented Professor Gilles Salles, Chair of the Clinical Hematology Department at the University of Lyon, France, and lead investigator of L-MIND.
L-MIND is designed to investigate the antibody tafasitamab in combination with lenalidomide in patients with r/r DLBCL who are not eligible for high-dose chemotherapy and autologous stem cell transplantation. Tafasitamab is an investigational humanized Fc-enhanced monoclonal antibody directed against CD19 and is currently in clinical development in blood cancer indications.
