About ADC Therapeutics

SA (NYSE:ADCT) 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

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), which exceeded the target primary endpoint. In September 2020, ADC Therapeutics submitted a Biologics License

Application to the U.S. Food and Drug Administration seeking accelerated approval 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.

is based in Lausanne (Biop le), Switzerland and has operations in London, the San Francisco Bay Area and New Jersey. For
