MorphoSys To Present New Phase 3 MANIFEST-2 Data on Pelabresib in Myelofibrosis in Oral Presentation at 2024 ASCO Annual Meeting
Additional ASCO 2024 poster presentation will include new findings from the Phase 2 study of tulmimetostat
MorphoSys AG (FSE: MOR; NASDAQ: MOR) today announced that new efficacy and safety data from the Phase 3 MANIFEST-2 trial of pelabresib, an investigational BET inhibitor, in combination with the JAK inhibitor ruxolitinib in JAK inhibitor-naïve patients with myelofibrosis will be highlighted during an oral presentation on Friday, May 31, at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. The congress is being held in Chicago, Illinois, from May 31 to June 4, 2024.
Additionally, new data from the Phase 2 study of tulmimetostat, an investigational next-generation dual inhibitor of EZH2 and EZH1, in patients with advanced solid tumors or hematologic malignancies will be showcased in a poster presentation at ASCO 2024.

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 been approved by any regulatory authorities. Its safety and efficacy have not been established.
The development of pelabresib was funded in part by The Leukemia and Lymphoma Society®.
About MANIFEST-2
MANIFEST-2 (NCT04603495) is a global, double-blind, Phase 3 clinical trial that randomized 430 JAK inhibitor-naïve adult patients with myelofibrosis 1:1 to receive pelabresib in combination with ruxolitinib or placebo plus ruxolitinib. The primary endpoint of the study is a 35% or greater reduction in spleen volume (SVR35) from baseline at 24 weeks. The key secondary endpoints of the study are the absolute change in total symptom score (TSS) from baseline at 24 weeks and the proportion of patients achieving a 50% or greater improvement in total symptom score (TSS50) from baseline at 24 weeks. TSS is measured using the myelofibrosis self-assessment form (MFSAF) v4.0, which asks patients to report the severity of seven common symptoms, rating each of them on a scale from 0 (absent) to 10 (worst imaginable).
Additional secondary endpoints include progression-free survival, overall survival, duration of the splenic and total symptom score response, hemoglobin response rate and improvement in bone marrow fibrosis, among others.
Constellation Pharmaceuticals, Inc., a MorphoSys company, is the MANIFEST-2 trial sponsor.
About Myelofibrosis
Myelofibrosis is a blood cancer – belonging to a group of diseases called myeloproliferative neoplasms – caused by genetic abnormalities in bone marrow stem cells and characterized by four hallmarks: enlarged spleen, anemia, impaired bone marrow microenvironment causing fibrosis, and debilitating disease-associated 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. While JAK inhibitors, the current standard of care, address some aspects of the disease, no agent provides broad disease control. There is an urgent need for novel, well-tolerated therapeutic options capable of changing the natural course of myelofibrosis to provide patients with deep and durable responses across its four hallmarks.
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 (EZH1 and EZH2) proteins to reactivate tumor suppressor genes or silencing the oncogenic pathways. 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, endometrial carcinoma and other solid tumors, diffuse large B-cell lymphoma, peripheral T-cell lymphoma, BAP1-mutated mesothelioma and castration-resistant prostate cancer. The primary objectives of the trial include determining the maximum tolerated dose and/or recommended Phase 2 dose and evaluating antitumor activity of tulmimetostat monotherapy. The safety and efficacy of tulmimetostat have not been established.
