About ADC Therapeutics

ADC Therapeutics SA /zigman2/quotes/214411413/composite ADCT -9.91% is a late clinical-stage oncology-focused biotechnology company pioneering the development and commercialization of highly potent and targeted antibody drug conjugates (ADCs) for patients with hematological malignancies and solid tumors. The Company develops ADCs by applying its decades of experience in this field and using next-generation pyrrolobenzodiazepine (PBD) technology to which ADC Therapeutics has proprietary rights for its targets. Strategic target selection for PBD-based ADCs and substantial investment in early clinical development have enabled ADC Therapeutics to build a deep clinical and research pipeline of therapies for the treatment of hematological and solid tumor cancers. The Company has multiple PBD-based ADCs in ongoing clinical trials, ranging from first in human to confirmatory Phase 3 clinical trials, in the USA and Europe, and numerous preclinical ADCs in development.

Loncastuximab tesirine (Lonca, formerly ADCT-402), the Company’s lead product candidate, has been evaluated in a 145-patient pivotal Phase 2 clinical trial for the treatment of relapsed or refractory diffuse large B-cell lymphoma (DLBCL) that showed a 48.3% overall response rate (ORR). In September 2020, ADC Therapeutics submitted a BLA to the US FDA for Lonca for the treatment of patients with relapsed or refractory DLBCL. Camidanlumab tesirine (Cami, formerly ADCT-301), the Company’s second lead product candidate, is being evaluated in a 100-patient pivotal Phase 2 clinical trial for the treatment of relapsed or refractory Hodgkin lymphoma (HL) after having shown an 86.5% ORR in HL patients in a Phase 1 clinical trial. The Company is also evaluating Cami as a novel immuno-oncology approach for the treatment of various advanced solid tumors.

ADC Therapeutics is based in Lausanne (Biopôle), Switzerland and has operations in London, the San Francisco Bay Area and New Jersey.
