LAUSANNE, Switzerland, July 09, 2019 (GLOBE NEWSWIRE) -- ADC Therapeutics, an oncology drug discovery and development company that specializes in the development of antibody drug conjugates (ADCs), today announced the final close of a $103 million Series E financing expansion, bringing the total gross proceeds of the Series E round to $303 million. The final close of the expansion round includes a $25 million investment from a new U.S.-based institutional investor, as well as additional investment from existing investors that participated in the previously announced $76 million Series E financing expansion.   

Chris Martin, DPhil, Chief Executive Officer of ADC Therapeutics, said, “We are delighted to welcome a new blue-chip institutional investor to our shareholder base. This financing provides us with a strong balance sheet to fund preparations for a potential Biologics License Application (BLA) for ADCT-402 (loncastuximab tesirine) in relapsed or refractory diffuse large B-cell lymphoma (DLBCL) in the second half of 2020, as well as for initiating in the coming months a pivotal Phase II trial of ADCT-301 (camidanlumab tesirine) in Hodgkin lymphoma based on our recent end of Phase I meeting with the U.S. Food and Drug Administration.”  

ADC Therapeutics plans to complete enrollment in its pivotal Phase II trial of ADCT-402 in a broad population of patients with relapsed or refractory DLBCL imminently and report interim results in the second half of 2019. ADCT-402 is also being evaluated in a Phase Ib trial in combination with ibrutinib in patients with relapsed or refractory DLBCL or mantle cell lymphoma (MCL) and a Phase Ib trial in combination with durvalumab in patients with relapsed or refractory DLBCL, MCL or follicular lymphoma. In addition, the Company plans to commence a pivotal Phase II trial of ADCT-301 in patients with relapsed or refractory Hodgkin lymphoma in the coming months. ADCT-301, with its novel mechanism of action targeting regulatory T cells, is also being evaluated in a Phase Ib trial in patients with selected advanced solid tumors.
