On February 5, 2024 Novartis reported that it has entered into an agreement to make a voluntary public takeover offer to acquire MorphoSys AG (FSE: MOR; NASDAQ: MOR), a Germany-based, global biopharmaceutical company developing innovative medicines in oncology (Press release, Novartis, FEB 5, 2024, View Source [SID1234639847]). The acquisition, which is subject to customary closing conditions, including a minimum acceptance threshold of 65% of outstanding shares tendered in the takeover offer and regulatory approvals, further expands and complements Novartis pipeline in oncology, one of its priority therapeutic areas, while also enhancing Novartis global footprint in hematology.

Upon completion of the acquisition, Novartis will own pelabresib (CPI-0610), a novel and potentially practice changing treatment option with a well-tolerated safety profile provided in combination with ruxolitinib for patients with myelofibrosis (MF). It will also include tulmimetostat (CPI-0209), an early-stage investigational dual inhibitor of enhancer of zeste homolog 1 and 2 (EZH1 and EZH2) proteins currently being tested in patients with solid tumors or lymphomas.
Pelabresib in combination with ruxolitinib recently met its primary endpoint of spleen volume reduction in the Phase 3 MANIFEST-2 study in JAK inhibitor-naive MF patients1. The combination also demonstrated favorable trends in symptom improvement as evidenced by key secondary endpoints of absolute and 50% change in total symptom score (TSS) at week 24 compared to baseline. All four clinical hallmarks of disease in myelofibrosis – splenomegaly, disease-associated symptoms, anemia and bone marrow fibrosis – were improved with the pelabresib and ruxolitinib combination. In the earlier Phase 2 MANIFEST trial, the third arm of the study with a patient population comparable to MANIFEST-2, showed durable improvements in both spleen volume and total symptom score up to week 602. Regulatory filing with the U.S. FDA is planned for the second half of 2024.
"We are excited about the opportunity of bringing pelabresib, a potential next-generation treatment combined with ruxolitinib, to people living with myelofibrosis, a rare and debilitating form of blood cancer," said Shreeram Aradhye, M.D., President, Development and Chief Medical Officer of Novartis. "With the planned acquisition of MorphoSys, we aim to further strengthen our leading pipeline and portfolio in oncology, adding to our capabilities and expertise. Building on our long-standing development partnership with MorphoSys, we look forward to continuing our work together to realize the full impact and value of their investigational medicines for patients with unmet needs."
Pelabresib is an investigational small molecule designed to promote anti-tumor activity by selectively inhibiting the function of bromodomain and extra-terminal domain (BET) proteins to decrease the expression of abnormally expressed genes in cancer. Pelabresib is also being studied in patients with essential thrombocythemia (ET), which is currently in Phase 2 in second line of treatment. Besides pelabresib, MorphoSys’ pipeline includes a broad portfolio of partnered assets of which some are in partnership with Novartis, including ianalumab (VAY736) which is studied across multiple immunological diseases and in hematology.
Transaction Details
Under the agreed transaction, which has been unanimously approved by the Board of Directors of both companies, Novartis will make a voluntary public takeover offer for all no-par value bearer shares of MorphoSys AG for EUR 68 per share (or an aggregate of EUR 2.7bn).
The transaction is subject to customary closing conditions, including acceptance of the takeover offer by at least 65% of MorphoSys AG’s outstanding shares and receipt of regulatory approvals and is expected to close in the first half of 2024. Until the transaction closes, MorphoSys AG will continue to operate as a separate, independent company.
About Pelabresib (CPI-0610)
Pelabresib (CPI-0610) is an investigational small molecule designed to promote anti-tumor activity selectively 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 approved by any regulatory authorities. The development of pelabresib was funded in part by The Leukemia and Lymphoma Society.
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 (CPI-0209),
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.
