Genmab and ProfoundBio have entered into a definitive agreement for Genmab to acquire ProfoundBio in an all-cash transaction.
ProfoundBio is a privately-owned clinical-stage biotechnology company developing next-generation antibody-drug conjugates (ADCs) and ADC technologies for the treatment of certain cancers, including ovarian cancer and other folate receptor alpha (FRα)-expressing solid tumors. Genmab will acquire ProfoundBio for $1.8 billion in cash.
The transaction will further broaden Genmab’s mid- to late-stage clinical pipeline and strengthen and complement Genmab’s already validated suite of proprietary technology platforms. The acquisition will give Genmab worldwide rights to ProfoundBio’s portfolio of next-generation ADCs, which consists of three clinical and multiple preclinical programs including rinatabart sesutecan (Rina-S), a potential best-in-class, clinical-stage, FRα-targeted, Topo1 ADC, currently in Phase 2 of a Phase 1/2 clinical trial, for the treatment of ovarian cancer and other FRα-expressing solid tumors. In addition, the combination of ProfoundBio’s novel ADC technology platforms with Genmab’s proprietary antibody platforms will potentially create new opportunities to generate and develop new medicines with the potential to transform the treatment of cancer and improve the lives of patients.
The addition of Rina-S to Genmab’s portfolio will enable Genmab to deepen its presence in the gynecologic oncology space and establish a firm foundation in solid tumors. As a potential best-in-class ADC, Rina-S aims to address a broader patient population than first-generation FRα-targeted ADCs. Based on the data from the ongoing Phase 1/2 clinical trial Genmab intends to broaden the development plans for Rina-S within ovarian cancer and other FRα-expressing solid tumors. In January 2024, the U.S. Food and Drug Administration (U.S. FDA) granted Fast Track designation to Rina-S for the treatment of patients with FRα-expressing high-grade serous or endometrioid platinum-resistant ovarian cancer.
“The proposed acquisition of ProfoundBio firmly aligns with our long-term strategy and our ambitious 2030 vision, to impact the lives of patients through innovative antibody medicines,” said Jan van de Winkel, Ph.D., President and Chief Executive Officer of Genmab. “We believe that ProfoundBio’s ADC candidates, proprietary technology platforms and talented team will be a great addition to Genmab and that, together, we will be able to accelerate the development of innovative, differentiated antibody therapies for cancer patients.”
“Genmab shares our team’s mission of developing novel therapies to improve outcomes for cancer patients. Genmab’s deep expertise in antibody drug development and commercialization makes this a compelling union that will allow us to rapidly develop and realize the full potential of our ADC therapies to benefit patients,” said Baiteng Zhao, Ph.D., ProfoundBio’s co-founder, Chief Executive Officer and Chairman of the Board.
