MorphoSys Completes Enrollment of Phase 3 MANIFEST-2 Study of Pelabresib in Myelofibrosis with Topline Results Expected by End of 2023

Enrollment of Phase 3 frontMIND study of tafasitamab in first-line diffuse large B-cell lymphoma is also complete


MorphoSys AG (FSE: MOR; NASDAQ: MOR) announced today that enrollment is complete for MANIFEST-2, the ongoing Phase 3 study exploring the efficacy and safety of pelabresib, an investigational BET inhibitor, in combination with ruxolitinib versus ruxolitinib alone in patients with myelofibrosis who have not previously been treated with a JAK inhibitor (JAK inhibitor-naïve). The topline data are now expected by the end of 2023, earlier than previously anticipated.

Myelofibrosis – which belongs to a group of diseases called myeloproliferative disorders – is a difficult-to-treat form of blood cancer with limited treatment options. JAK inhibitors are a current standard of care treatment for myelofibrosis, which focus on relieving symptoms of the disease rather than treating its cause. But, with this treatment strategy, only about half of patients attain adequate disease control, and durability of response is often limited. Clinical data suggest synergistic effects between BET inhibition and JAK inhibition in myelofibrosis, supporting the potential of this combination therapy.

“With so many patients left behind by current treatment options for myelofibrosis, there is a critical need for regimens that elevate the standard of care for patients suffering from this debilitating disease,” said Tim Demuth, M.D., Ph.D., Chief Research and Development Officer, MorphoSys. “Now that MANIFEST-2 has completed enrollment earlier than anticipated, we look forward to the coming insights into the therapeutic potential of pelabresib in combination with ruxolitinib for JAK inhibitor-naïve patients with myelofibrosis. MANIFEST-2 is the latest milestone in our efforts to improve outcomes for blood cancer patients and is a testament to our continued commitment to the myelofibrosis community.”

MANIFEST-2 is a global, multicenter, double-blind, Phase 3 study of more than 400 patients who were naïve to JAK inhibitors. Patients were randomized 1:1 to pelabresib in combination with ruxolitinib or placebo plus ruxolitinib. The primary endpoint of the trial is the proportion of patients who achieve a 35% or greater reduction in spleen volume at week 24 (known as SVR35). Reduction in spleen size is an important clinical endpoint in myelofibrosis because spleen enlargement reflects disease activity and can cause significant pain and discomfort.

The key secondary endpoint is the proportion of patients achieving a 50% or greater improvement in total symptom score, as measured by the Myelofibrosis Symptom Assessment Form v4.0, at week 24. Patients with myelofibrosis experience a severely diminished quality of life due to symptoms such as severe fatigue, fever and weight loss. The Myelofibrosis Symptom Assessment Form is a validated self-assessment tool designed specifically for myelofibrosis patients that can track changes in these symptoms.

The MANIFEST-2 trial is supported by findings from the Phase 2 MANIFEST trial of pelabresib in combination with ruxolitinib in patients with myelofibrosis, including those who were JAK inhibitor-naïve. Updated results from MANIFEST presented at the American Society of Hematology 2022 Annual Meeting and Exposition suggest that pelabresib in combination with ruxolitinib provided prolonged improvement in both spleen size and symptom severity at and beyond 24 weeks.

Enrollment of the Phase 3 frontMIND study is also complete, with more than 880 patients enrolled in the trial. frontMIND is a global, multicenter, randomized, double-blind, placebo-controlled trial exploring tafasitamab, marketed in the U.S. as Monjuvi® and outside the U.S. by Incyte as Minjuvi®, plus lenalidomide in addition to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) versus R-CHOP alone as a first-line treatment for high-intermediate and high-risk patients with diffuse large B-cell lymphoma. The topline data from this study are expected in the second half of 2025.
 

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 Myelofibrosis

Myelofibrosis – one of a group of diseases called myeloproliferative disorders – is a difficult-to-treat form of blood cancer that’s characterized by bone marrow fibrosis (a buildup of scar tissue in the bone marrow), spleen enlargement and anemia (low red blood cell counts) often requiring periodic blood transfusions. Patients with myelofibrosis can also suffer from a range of physical symptoms, including severe fatigue, night sweats, itching, increased bleeding and significant pain caused by their enlarged spleen. For many living with myelofibrosis, the combination of symptoms often severely impacts their quality of life. At diagnosis, several factors, such as age, genetics and bloodwork, help determine a patient’s long-term prognosis. About 90% of newly diagnosed patients have intermediate- to high-risk disease, which has a worse prognosis and a higher likelihood of disease-associated symptoms. Today, myelofibrosis treatments revolve around the use of medications called JAK inhibitors, which focus on relieving symptoms of myelofibrosis rather than treating its cause. But with this strategy, only about 50% of patients achieve adequate symptom control, and, unfortunately, that relief fades with time for many. Patients suffering from myelofibrosis are in critical need of treatment options that not only address their symptoms but also change the overall course of their disease.

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 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. Constellation Pharmaceuticals, Inc., a MorphoSys company, is the MANIFEST trial sponsor.
