MorphoSys Presents Clinical Data on MOR208 plus Lenalidomide in Aggressive Lymphoma (R/R DLBCL) at ASH 2017 Conference
- Preliminary median progression-free survival of 11.3 months
- Objective response rate (ORR) of 52%, complete remission rate (CR) of 32%
- No unexpected toxicities observed; no infusion-related reactions reported for MOR208
- MOR208 plus lenalidomide recently received FDA Breakthrough Therapy designation for non-transplant eligible patients with R/R DLBCL
MorphoSys AG (FSE: MOR; Prime Standard Segment; TecDAX, OTC: MPSYY) today presented clinical data from the ongoing phase 2 clinical trial (L-MIND) evaluating MOR208 in combination with lenalidomide in patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL). DLBCL is the most frequent type of malignant lymphoma worldwide and accounts for approximately 30% of all non-Hodgkin lymphomas. Data will be reported in a poster presentation (available for download) at the 59th American Society of Hematology (ASH) Annual Meeting in Atlanta, Georgia/USA. MOR208 is an investigational Fc-engineered monoclonal antibody directed against CD19.
The data presented at ASH formed the basis for the Breakthrough Therapy designation recently awarded by the FDA for MOR208, in combination with lenalidomide, for the treatment of non-transplant eligible patients with R/R DLBCL.
At data cut-off (June 13, 2017), 51 patients had been enrolled in the study, of whom 44 were evaluable for efficacy assessments. Preliminary data show an objective response in 23 out of 44 patients (ORR: 52%), 19 (83%) of whom show ongoing responses. Complete remission was seen in 14 out of 44 patients (CR: 32%). The median time to response was 1.8 months, the median time to complete response was 2.3 months. The preliminary median progression-free survival (PFS) based on Kaplan Meier calculation was 11.3 months.
No unexpected toxicities were observed for the treatment combination and no infusion-related reactions were reported for MOR208. The most frequent adverse events with a toxicity grading of 3 or higher were neutropenia, thrombocytopenia, and leukopenia, observed in 35%, 10%, and 8% of patients, respectively. Pneumonia and hypokalemia were reported for 10% and 8% of the patients. To date, 45% of patients required a reduction of their lenalidomide dose, from a starting dose of 25mg daily.
The trial has recently completed patient recruitment as required by the study protocol. To date, 81 patients have been enrolled.
"We are very encouraged by the updated clinical trial results from the ongoing L-MIND trial, especially the complete responses and the duration of responses we have seen so far. DLBCL is a very aggressive lymphoma. In particular, those patients with relapsed or refractory DLBCL who are not eligible for high-dose chemotherapy and autologous stem cell transplantation are in need of more therapeutic options. Based on the FDA Breakthrough Therapy designation we recently obtained, we intend to develop MOR208 together with lenalidomide as a potential new treatment option for this patient group as quickly as possible," commented Dr. Malte Peters, Chief Development Officer of MorphoSys AG.
The L-MIND trial (Lenalidomide plus MOR208 in DLBCL) is a single-arm, open-label, multicenter study of MOR208 in combination with lenalidomide. The trial is enrolling patients with relapsed or refractory DLBCL after up to three prior lines of therapy, with at least one prior therapy including an anti-CD20 targeting therapy (e.g. rituximab). Patients could not be candidates for high-dose chemotherapy and autologous stem cell transplantation. Patients enrolled had a median age of 74 years.

About CD19 and MOR208
CD19 is broadly and homogeneously expressed across different B cell malignancies including DLBCL and CLL. CD19 has been reported to enhance B cell receptor (BCR) signaling, which is assumed important for B cell survival, making CD19 a potential target in B cell malignancies.
MOR208 (previously Xmab(R)5574) is an investigational Fc-enhanced monoclonal antibody directed against CD19, a prominent marker present on the surface of B-cells. Fc-modification of MOR208 is intended to lead to a significant potentiation of antibody-dependent cell-mediated cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP), thus aiming to improve a key mechanism of tumor cell killing. Furthermore, MOR208 has been observed in preclinical models to induce direct apoptosis by binding to CD19, which is assumed to be a crucial component for B cell receptor (BCR) signaling.
MorphoSys AG is clinically investigating MOR208 as a therapeutic option in B cell malignancies in a number of ongoing combination trials. An open-label phase 2 combination trial (L-MIND study) was started in March 2016 and is designed to investigate the safety and efficacy of MOR208 in combination with lenalidomide in patients with relapsed/refractory DLBCL. The phase 2/3 B-MIND study was started in August 2016 and transitioned into its phase 3 pivotal part in June 2017 following a recommendation of the IDMC based on the available data from the phase 2 initial safety evaluation. The B-MIND study is designed to investigate MOR208 in combination with the chemotherapeutic agent bendamustine in comparison to the combination of the anti-CD20 antibody rituximab plus bendamustine in patients with relapsed/refractory DLBCL who are not eligible for high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT). Furthermore, MOR208 is currently being clinically investigated in combination with idelalisib or venetoclax in patients with relapsed/refractory CLL after discontinuation of a prior Bruton tyrosine kinase (BTK) inhibitor therapy (e.g. ibrutinib).
