MorphoSys AG (FSE: MOR; NASDAQ: MOR) will host a virtual investor event on Wednesday, June 21, at 9:00 a.m. EDT / 3:00 p.m. CEST.

During the event, Jean-Paul Kress, M.D., MorphoSys’ Chief Executive Officer, and Tim Demuth, M.D., Ph.D., MorphoSys’ Chief Research and Development Officer, will discuss the potential of the company’s lead investigational asset, pelabresib.

Topics will include an overview of the disease burden for patients with myelofibrosis, including treatment gaps; a recap of encouraging findings in myelofibrosis from the pelabresib Phase 2 MANIFEST study in combination with ruxolitinib and background on the Phase 3 MANIFEST-2 study, which will report topline results by the end of 2023; and new proof of concept results and expansion plans for pelabresib in other myeloid diseases. The full agenda is below.

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-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. Topline data from the MANIFEST-2 study will be available by the end of 2023. 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. 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.
