MorphoSys AG: Ad hoc: Primary Endpoint of L-MIND, a Combination Study of Tafasitamab (MOR208) and Lenalidomide, has been met, Confirming Previously Published Activity
Thursday, May 16, 2019 3:45 PM
PLANEGG/MUNICH, GERMANY / ACCESSWIRE / May 16, 2019 / MorphoSys AG (FSE: MOR; Prime Standard Segment; MDAX & TecDAX; Nasdaq: MOR) today announced results from the primary analysis (cut-off date November 30, 2018) of the ongoing single-arm phase 2 clinical trial known as L-MIND. The results overall confirm earlier reported interim data from this trial. L-MIND is designed to investigate the antibody tafasitamab (MOR208) in combination with lenalidomide in patients with relapsed or refractory diffuse large B cell lymphoma (r/r DLBCL) who are ineligible 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.
The 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.
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). The median progression free survival (mPFS) was 12.1 months with a median follow-up of 17.3 months. The medium duration of response (mDoR) was 21.7 months. These results provide overall confirmation of the strong L-MIND data previously published at ASH in December 2018. These data showed an ORR of 58% with a CR rate of 33%; the mPFS was 16.2 months; data was assessed by the investigators.

About CD19 and tafasitamab (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.
Tafasitamab (MOR208) is an investigational humanized Fc-engineered monoclonal antibody directed against CD19. Fc-modification of tafasitamab 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. Tafasitamab has been observed in preclinical models to induce direct apoptosis by binding to CD19, which is assumed to be involved in B cell receptor (BCR) signaling.
MorphoSys is clinically investigating tafasitamab 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) is investigating the safety and efficacy of tafasitamab in combination with lenalidomide in patients with relapsed/refractory DLBCL who are not eligible for high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT). Based on interim data from L-MIND, in October 2017 the U.S. FDA granted Breakthrough Therapy Designation for tafasitamab plus lenalidomide in this patient population. The pivotal phase 2/3 B-MIND study is designed to investigate tafasitamab in combination with the chemotherapeutic agent bendamustine in patients with relapsed/refractory DLBCL who are not eligible for high-dose chemotherapy (HDC) and autologous stem cell transplantation (ASCT) in comparison to the combination of the anti-CD20 antibody rituximab plus bendamustine. In addition, tafasitamab is currently being investigated in patients with relapsed/refractory CLL/SLL after discontinuation of a prior Bruton tyrosine kinase (BTK) inhibitor therapy (e.g. ibrutinib) in combination with idelalisib or venetoclax.
MorphoSys (FSE & NASDAQ: MOR) is a clinical-stage biopharmaceutical company dedicated to the discovery, development and commercialization of exceptional, innovative therapies for patients suffering from serious diseases. The focus is on cancer. Based on its leading expertise in antibody, protein and peptide technologies, MorphoSys, together with its partners, has developed and contributed to the development of more than 100 product candidates, of which 29 are currently in clinical development. In 2017, Tremfya(R), marketed by Janssen for the treatment of plaque psoriasis, became the first drug based on MorphoSys's antibody technology to receive regulatory approval. The Company's most advanced proprietary product candidate, tafasitamab, has been granted U.S. FDA breakthrough therapy designation for the treatment of patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Headquartered near Munich, Germany, the MorphoSys group, including the fully owned U.S. subsidiary MorphoSys US Inc., has approximately 330 employees. More information at https://www.morphosys.com.
