LAUSANNE, Switzerland I October 23, 2017 I ADC Therapeutics (ADCT), an oncology drug discovery and development company that specializes in the development of proprietary Antibody Drug Conjugates (ADCs) targeting major cancers, today announced that it has raised $200 million through a private placement. The financing was oversubscribed and supported by both existing and new investors, including Auven Therapeutics, Redmile, the Wild Family Office and AstraZeneca.

The proceeds will be used to progress ADCT-301 and ADCT-402 into planned registrational trials in 2018. Both candidates are currently in four clinical studies in important sub-types of lymphoma and leukemia. ADCT will also advance ADCT-301 into a combination study for solid tumors. Further it will allow the Company to continue the development of the Phase I study of ADCT-502 in patients with advanced solid tumors with HER2 expression, to file INDs for ADCT-602 and ADCT-601, and to progress a pipeline of pre-clinical ADC programs. ADCT expects to have a total of eight programs in clinical development within 18 months.

Dr. Chris Martin, CEO of ADCT, said: “With more than 250 patients dosed, and encouraging data to be presented at the upcoming congress of the American Society of Hematology, this financing is a key step in our strategy and will enable us to accelerate our lead programs and to continue to develop our pipeline. This transaction also reflects the potential value to patients of rapidly developing these active drugs as stand alone and combination therapies. We continue to grow our pipeline of proprietary antibody-drug conjugates in important hematological and solid tumor indications both on our own and in partnerships.”

ADCT is focused on the development of proprietary ADCs incorporating highly potent pyrrolobenzodiazepine (PBD)-based warheads. ADCT’s clinical and preclinical programs target major types of both hematological malignancies and solid tumours. Since inception in 2012, the Company has raised $455 million to advance its pipeline of proprietary ADCs. The Company has four PBD-based antibody drug conjugates in six ongoing Phase Ia and Ib clinical trials in the USA and in Europe.
