Ad hoc: Primary Endpoint met in Real-World Data Study Demonstrating Clinical Superiority of the Combination of Tafasitamab and Lenalidomide compared to Lenalidomide alone

MorphoSys AG (FSE: MOR; Prime Standard Segment; MDAX & TecDAX; Nasdaq: MOR) today announced topline results from the primary analysis of the retrospective observational matched control cohort (Re-MIND). This study was designed to compare the effectiveness of lenalidomide monotherapy based on real-world patient data with the efficacy outcomes of the tafasitamab/lenalidomide combination, as investigated in MorphoSys's L-MIND trial (primary analysis results announced on June 22, 2019).

Re-MIND collected outcome data from 490 non-transplant eligible patients with relapsed/ refractory diffuse large B cell lymphoma (r/r DLBCL) who had received lenalidomide monotherapy in the U.S. and the EU in a real-world setting. Qualification criteria for matching patients of both studies were pre-specified. As a result, 76 eligible Re-MIND patients were identified and matched 1:1 to 76 of 80 L-MIND patients based on important baseline characteristics. Objective response rates (ORR) were validated based on this subset of 76 patients in Re-MIND and L-MIND, respectively.

The primary endpoint of Re-MIND has been met and shows a statistically significant superior best ORR of the tafasitamab/lenalidomide combination compared to lenalidomide monotherapy. ORR was 67.1% (95% confidence interval (CI): 55.4-77.5) for the tafasitamab/ lenalidomide combination, compared to 34.2% (CI: 23.7-46.0) for the lenalidomide monotherapy (p<0.0001). Superiority was consistently observed across all secondary endpoints, including complete response (CR) rate (tafasitamab/lenalidomide combination 39.5%; CI: 28.4-51.4 versus lenalidomide monotherapy 11.8%; CI: 5.6-21.3; p<0.0001), as well as in pre-specified statistical sensitivity analyses. In addition, there was a significant difference observed in overall survival, which was not reached in the tafasitamab/lenalidomide combination as compared to 9.3 months in the lenalidomide monotherapy (hazard ratio 0.47; CI: 0.30-0.73; p<0.0008).

About L-MIND
L-MIND is a single arm, open-label phase 2 study, investigating the combination of tafasitamab and lenalidomide in patients with relapsed or refractory diffuse large B cell lymphoma (DLBCL) after up to two prior lines of therapy, including an anti-CD20 targeting therapy (e.g. rituximab), who are not eligible for high-dose chemotherapy and subsequent autologous stem cell transplantation. The study's primary endpoint is objective response rate (ORR). Secondary outcome measures include duration of response (DoR), progression-free survival (PFS) and overall survival (OS). In May 2019, the study reached its primary completion. Primary analysis data with a cut-off date of November 30, 2018 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 were based on response rates assessed by an independent review committee for all 80 patients. Based on earlier reported interim data from L-MIND, in October 2017 the U.S. FDA granted Breakthrough Therapy Designation for tafasitamab plus lenalidomide in this patient population. MorphoSys is working towards completion of a BLA submission to the U.S. FDA based on L-MIND by end of 2019.

About RE-MIND
RE-MIND, an observational retrospective study, was designed to isolate the contribution of tafasitamab in the combination with lenalidomide and to prove the combinatorial effect. The study compares real-world response data of patients with relapsed or refractory diffuse large B cell lymphoma (r/r DLBCL) who received lenalidomide monotherapy with the efficacy outcomes of the tafasitamab-lenalidomide combination, as investigated in MorphoSys's L-MIND trial. RE-MIND collected the efficacy data from 490 r/r DLBCL patients in the U.S. and EU. Eligible patients were matched 1:1 to the L-MIND study population based on important baseline characteristics, such as relevant prognostic factors, laboratory characteristics and patient demographics.
