MorphoSys AG: MorphoSys Expects Topline Data from Phase 3 Study of Pelabresib in Myelofibrosis in Early 2024

MUNICH, GERMANY / ACCESSWIRE / January 9, 2023 / MorphoSys AG (FSE: MOR; NASDAQ: MOR) announced today that topline data from the ongoing Phase 3 MANIFEST-2 study - a global, randomized, double-blind clinical trial exploring pelabresib, an investigational BET inhibitor, in combination with ruxolitinib as a first-line treatment for patients with myelofibrosis - are expected to be available in early 2024. The company previously communicated that these data were expected in the first half of 2024. Jean-Paul Kress, M.D., Chief Executive Officer of MorphoSys, will provide further updates on the pelabresib program and the rest of the company's oncology pipeline at the 41st Annual J.P. Morgan Healthcare Conference on Wednesday, January 11, 2023, at 5:15 p.m. Pacific Standard Time in San Francisco, CA.

"For patients with myelofibrosis, depth and durability of responses are limited with current first-line therapy. The latest Phase 2 data suggest pelabresib may have the potential to enhance the standard of care, reaffirming our confidence in the Phase 3 MANIFEST-2 study," said Jean-Paul Kress. "We look forward to providing further updates on the pelabresib program and our other clinical programs during the J.P. Morgan Healthcare Conference."

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 is a type of bone marrow cancer that causes extensive scarring in the bone marrow, which disrupts the body's normal production of healthy blood cells. The result is a reduction in red blood cells, which can cause weakness and fatigue, and in platelets, which increases the risk of bleeding due to deficient clotting. Myelofibrosis often causes an enlarged spleen, significantly impacting a patient's quality of life. It is most often diagnosed in people older than 50 and can occur on its own (called primary myelofibrosis) or because of another bone marrow disorder.


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. A 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.
