A total of 117 patients have been enrolled in the trial.

At the 62^nd American Society of Hematology (ASH) Annual Meeting, the Company presented preliminary Phase 2 data consistent with Phase 1 results. Based on 47 evaluable patients as of August 24, 2020, Cami demonstrated an 83% overall response rate and no new safety signals were identified.

About Camidanlumab Tesirine (Cami)

Camidanlumab tesirine (Cami, formerly ADCT-301) is an antibody drug conjugate (ADC) comprised of a monoclonal antibody that binds to CD25 (HuMax®-TAC, licensed from Genmab A/S), conjugated to the pyrrolobenzodiazepine (PBD) dimer payload, tesirine. Once bound to a CD25-expressing cell, Cami is internalized into the cell where enzymes release the PBD-based warhead killing the cell. This applies to CD25-expressing tumor cells, and also to CD25-expressing Tregs. The intra-tumoral release of its PBD warhead may also cause bystander killing of neighboring tumor cells and PBDs have also been shown to induce immunogenic cell death. All of these properties of Cami may enhance immune-mediated anti-tumor activity. Cami is being evaluated in a pivotal Phase 2 clinical trial in patients with relapsed or refractory Hodgkin lymphoma (HL), as well as in a Phase 1a/1b clinical trial in patients with relapsed or refractory HL and non-Hodgkin lymphoma and a Phase 1b clinical trial as monotherapy and in combination with pembrolizumab in solid tumors.

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), which exceeded the target primary endpoint. On November 20, 2020, the U.S. Food and Drug Administration accepted the Biologics License Application, granting priority review and setting a Prescription Drug User Fee Act (PDUFA) target action date of May 21, 2021. Camidanlumab tesirine (Cami, formerly ADCT-301), the Company’s second lead product candidate, is being evaluated in a 117-patient pivotal Phase 2 clinical trial for the treatment of relapsed or refractory Hodgkin lymphoma (HL) for which preliminary data have demonstrated an 83% ORR, consistent with the Phase 1 clinical trial. The Company is also evaluating Cami in a Phase 1b clinical trial as a novel immuno-oncology approach for the treatment of various advanced solid tumors.
