MorphoSys Highlights Potential of Its Mid- to Late-Stage Oncology Pipeline at 2023 ASCO and EHA Annual Meetings

 

MorphoSys AG (FSE: MOR; NASDAQ: MOR) today announced that the latest data on multiple pipeline therapies will be presented during the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois from June 2 to 6, 2023 and at the European Hematology Association (EHA) Hybrid Congress in Frankfurt, Germany from June 8 to 11, 2023. Presentations will include data on pelabresib, an investigational BET inhibitor; tafasitamab, a CD19-targeting immunotherapy, marketed in the U.S. in partnership with Incyte as Monjuvi® and outside the U.S. by Incyte as Minjuvi®; and tulmimetostat, an investigational next-generation dual inhibitor of EZH2 and EZH1.

“With pelabresib, we have the near-term potential to improve the standard of care for patients with myelofibrosis and the opportunity to expand into other myeloid diseases where new treatment options are still needed,” said Tim Demuth, M.D., Ph.D., MorphoSys Chief Research and Development Officer. “The data we are presenting at ASCO and EHA showcase the breadth and depth of our mid- to late-stage pipeline. We are committed to addressing the critical needs of patients with blood cancers, including myeloid malignancies, and those with solid tumors.”

Pelabresib is being investigated in the Phase 2 MANIFEST study in patients with myelofibrosis and essential thrombocythemia and in the Phase 3 MANIFEST-2 study in combination with ruxolitinib as a first-line treatment for myelofibrosis. Myelofibrosis and essential thrombocythemia are both myeloproliferative neoplasms, which are types of blood cancers that begin with a genetic change in bone marrow stem cells. The presentations on pelabresib include:

  • An oral presentation at EHA and a poster discussion at ASCO on new preliminary results from MANIFEST Arm 4 exploring pelabresib as a monotherapy in patients with high-risk essential thrombocythemia who are refractory or intolerant to hydroxyurea, the chemotherapeutic agent most used to treat the disease.
  • A poster presentation at EHA showcasing clinical data from MANIFEST Arm 3 evaluating pelabresib in combination with ruxolitinib for the treatment of patients with myelofibrosis who had not previously been treated with a JAK inhibitor (previously presented at American Society of Hematology [ASH 2022] Annual Meeting and Exposition).
  • A poster presentation at EHA with clinical data from MANIFEST Arm 2 evaluating pelabresib as add-on therapy to ruxolitinib in myelofibrosis patients with a suboptimal response or disease progression following treatment with ruxolitinib (previously presented at ASH 2022).

Monjuvi in combination with lenalidomide was investigated in the Phase 2 L-MIND study in patients with relapsed or refractory diffuse large B-cell lymphoma. The presentations on Monjuvi include:

  • A poster presentation at EHA of final five-year efficacy and safety data from L-MIND (previously presented at American Association for Cancer Research Annual Meeting 2023). 
  • An e-publication at ASCO and EHA of a new five-year sub-group analysis from L-MIND.

Tulmimetostat is being evaluated in a Phase 1/2 trial in patients with advanced solid tumors or lymphomas, including ARID1A-mutated ovarian clear cell carcinoma and endometrial carcinoma, BAP1-mutated mesothelioma, and peripheral T-cell lymphoma. Tulmimetostat was designed to improve on first-generation EZH2 inhibitors through increased potency, longer residence time on target and a longer half-life, offering the potential for enhanced anti-tumor activity.

  • At ASCO, preliminary results from the Phase 2 portion of the study evaluating tulmimetostat across multiple tumor types will be presented during a poster session.

About Pelabresib
Pelabresib (CPI-0610) is an investigational selective small molecule designed to promote anti-tumor activity by inhibiting the function of bromodomain and extra-terminal domain (BET) proteins to decrease the expression of abnormally expressed genes in cancer. Pelabresib is being investigated as a treatment for myelofibrosis and has not yet been evaluated or approved by any regulatory authorities.

 About MANIFEST
MANIFEST (NCT02158858) is an open-label Phase 2 clinical trial of pelabresib in patients with myelofibrosis.

The MANIFEST trial is evaluating pelabresib in combination with ruxolitinib in JAK-inhibitor-naïve myelofibrosis patients (Arm 3), with a primary endpoint of the proportion of patients with a ≥35% spleen volume reduction from baseline (SVR35) after 24 weeks of treatment. The trial is also evaluating pelabresib either as a monotherapy in patients who are resistant to, intolerant of, or ineligible for ruxolitinib and no longer on the drug (Arm 1) or as add-on therapy in combination with ruxolitinib in patients with a suboptimal response to ruxolitinib or myelofibrosis progression (Arm 2). Patients in Arms 1 and 2 are being stratified based on transfusion-dependent (TD) status. The primary endpoint for the patients in cohorts 1A and 2A, who were TD at baseline, is conversion to transfusion independence for 12 consecutive weeks. The primary endpoint for patients in cohorts 1B and 2B, who were not TD at baseline, is the proportion of patients with a ≥35% spleen volume reduction from baseline after 24 weeks of treatment. The study is also evaluating pelabresib as a monotherapy in patients with high-risk essential thrombocythemia who are intolerant of, or refractory to, hydroxyurea (Arm 4). The primary endpoint for patients in Arm 4 is complete hematological response rate after one cycle, or 21 days, of treatment. Constellation Pharmaceuticals, Inc., a MorphoSys company, is the MANIFEST trial sponsor.

About MANIFEST-2  

MANIFEST-2 (NCT04603495) is a global, double-blind, randomized Phase 3 clinical trial with pelabresib in combination with ruxolitinib versus placebo plus ruxolitinib in JAK inhibitor-naïve patients with myelofibrosis. The primary endpoint of the study is a 35% or greater reduction in spleen volume (SVR35) from baseline at 24 weeks. The key secondary endpoint of the study is a 50% or greater improvement in total symptom score (TSS50) from baseline at 24 weeks. Constellation Pharmaceuticals, Inc., a MorphoSys company, is the MANIFEST-2 trial sponsor.

About Tafasitamab 

Tafasitamab is a humanized Fc-modified cytolytic CD19-targeting monoclonal antibody. In 2010, MorphoSys licensed exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc. Tafasitamab incorporates an XmAb® engineered Fc domain, which mediates B-cell lysis through apoptosis and immune effector mechanism including Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC) and Antibody-Dependent Cellular Phagocytosis (ADCP). 

In the United States, Monjuvi® (tafasitamab-cxix) is approved by the U.S. Food and Drug Administration in combination with lenalidomide for the treatment of adult patients with relapsed or refractory DLBCL not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT). This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s). 

In Europe, Minjuvi® (tafasitamab) received conditional marketing authorization in combination with lenalidomide, followed by Minjuvi monotherapy, for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not eligible for autologous stem cell transplant (ASCT). 

Tafasitamab is being clinically investigated as a therapeutic option in B-cell malignancies in several ongoing combination trials.

 Important Safety Information 

What are the possible side effects of MONJUVI? 

MONJUVI may cause serious side effects, including: 

  •      Infusion reactions. Your healthcare provider will monitor you for infusion reactions during your infusion of MONJUVI. Tell your healthcare provider right away if you get fever, chills, rash, flushing, headache, or shortness of breath during an infusion of MONJUVI. 
  •      Low blood cell counts (platelets, red blood cells, and white blood cells). Low blood cell counts are common with MONJUVI, but can also be serious or severe. Your healthcare provider will monitor your blood counts during treatment with MONJUVI. Tell your healthcare provider right away if you get a fever of 100.4°F (38°C) or above, or any bruising or bleeding. 
  •      Infections. Serious infections, including infections that can cause death, have happened in people during treatments with MONJUVI and after the last dose. Tell your healthcare provider right away if you get a fever of 100.4°F (38°C) or above, or develop any signs and symptoms of an infection. 

The most common side effects of MONJUVI include:  

  •      Feeling tired or weak 
  •      Diarrhea 
  •      Cough 
  •      Fever 
  •      Swelling of lower legs or hands 
  •      Respiratory tract infection 
  •      Decreased appetite 

These are not all the possible side effects of MONJUVI. 

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. 

Before you receive MONJUVI, tell your healthcare provider about all your medical conditions, including if you: 

  •      Have an active infection or have had one recently. 
  •      Are pregnant or plan to become pregnant. MONJUVI may harm your unborn baby. You should not become pregnant during treatment with MONJUVI. Do not receive treatment with MONJUVI in combination with lenalidomide if you are pregnant because lenalidomide can cause birth defects and death of your unborn baby.

About L-MIND 

The L-MIND trial was a single arm, open-label Phase 2 study (NCT02399085) investigating the combination of tafasitamab and lenalidomide in patients with relapsed or refractory diffuse large B-cell lymphoma who had at least one, but no more than three, prior lines of therapy, including an anti-CD20 targeting therapy (e.g., rituximab), who were not eligible for high-dose chemotherapy or refused subsequent autologous stem cell transplant. The study’s primary endpoint was overall response rate. Secondary outcome measures included duration of response, progression-free survival and overall survival. In May 2019, the study reached its primary completion.

About Tulmimetostat

Tulmimetostat (CPI-0209) is an investigational compound designed to exert anti-tumor activity by inhibiting the function of enhancer of zeste homolog 1 and 2 (EZH2 and EZH1) proteins to reactivate silenced genes like tumor suppressor genes. Tulmimetostat is being tested as a once-daily oral treatment in a Phase 1/2 trial (NCT04104776) in patients with advanced solid tumors or lymphomas, including ARID1A-mutated ovarian clear cell carcinoma and endometrial carcinoma, diffuse large B-cell lymphoma, peripheral T-cell lymphoma, BAP1-mutated mesothelioma and castration-resistant prostate cancer. The primary outcome measures include frequency of dose-limiting toxicities, maximum tolerate dose and overall response rate.
