Constellation is a clinical-stage biopharmaceutical company using its expertise in epigenetics to discover and develop novel therapeutics that address serious unmet medical needs in patients with various forms of cancer. Constellation?s two lead product candidates, pelabresib (CPI-0610), a BET inhibitor, and CPI-0209, a second-generation EZH2 inhibitor, are in mid- to late-stage clinical trials and have broad therapeutic potential to offer meaningful benefits to patients with various hematological and solid tumors. Pelabresib has the potential to be a first- and best-in-class BET inhibitor and is currently in Phase 3 clinical trials for myelofibrosis, a bone marrow cancer that disrupts the body?s normal production of blood cells. CPI-0209 is currently in Phase 2 with best-in-class potential for treating hematological and solid tumors. Constellation?s pipeline also includes numerous preclinical compounds. ?This transformational acquisition represents a major step forward for MorphoSys as we bolster our position in hematology-oncology,? said Jean-Paul Kress, M.D., Chief Executive Officer of MorphoSys. ?Both pelabresib and CPI-0209 have broad potential and we look forward to unlocking their full benefits for cancer patients. Our existing clinical and commercial expertise is ideally suited to accelerate Constellation?s programs, enabling us to maximize Constellation?s potential and bring these novel therapies to market. With Constellation?s high-potential product candidates, complementary R&D capabilities, and outstanding team, we can further advance our mission in the fight against cancer.? ?We are proud that MorphoSys has recognized the strength of our team, our expertise in epigenetics, and our high-potential oncology development pipeline and discovery programs,? said Jigar Raythatha, President and Chief Executive Officer of Constellation. ?Becoming part of MorphoSys creates an industry leader with commercial capabilities, a deep R&D pipeline and complementary small molecule and biologics discovery and translational capabilities, as well as the financial strength to compete to win. Our shareholders will receive attractive, immediate and certain cash value for their shares, the employees of the combined entity will have a broader platform and greater opportunities, and patients will potentially benefit from innovative new therapies that address serious unmet needs.?
