New clinical data highlight potential of novel pyrrolobenzodiazepine-based antibody drug conjugates for the treatment of relapsed or refractory lymphomas

LAUSANNE, Switzerland, Nov. 14, 2018 (GLOBE NEWSWIRE) -- ADC Therapeutics, an oncology drug discovery and development company that specializes in the development of proprietary antibody drug conjugates (ADCs), today announced that data from Phase I clinical trials of ADCT-402 (loncastuximab tesirine) and ADCT-301 (camidanlumab tesirine) have been selected for oral and poster presentations at the 60^th American Society of Hematology (ASH) Annual Meeting, which is being held December 1-4 in San Diego.

Jay Feingold, MD, PhD, Chief Medical Officer and Senior Vice President of Clinical Development at ADC Therapeutics, said, “We look forward to sharing updated data from our first-in-human clinical trials of ADCT-402 and ADCT-301 in multiple subtypes of lymphoma at the 2018 ASH Annual Meeting. Interim data show that ADCT-402, which targets CD19, has demonstrated durable single-agent anti-tumor activity in patients with diffuse large B-cell lymphoma, follicular lymphoma and mantle cell lymphoma who have failed other therapies or have no available treatment options. In addition, new data on ADCT-301 highlight the CD25-targeting ADC’s impressive overall and complete response rates in heavily pretreated patients with classical Hodgkin lymphoma, as well as its encouraging clinical activity in T-cell lymphoma.”

About ADCT-402

ADCT-402 (loncastuximab tesirine) is an antibody drug conjugate (ADC) composed of a humanized monoclonal antibody that binds to human CD19, conjugated through a linker to a pyrrolobenzodiazepine (PBD) dimer toxin. Once bound to a CD19-expressing cell, ADCT-402 is internalized into the cell where enzymes release the PBD-based warhead. CD19 is a clinically validated target for the treatment of B-cell malignancies. The PBD-based warhead has the ability to form highly cytotoxic DNA interstrand cross-links, blocking cell division and resulting in cell death. ADCT-402 is being evaluated in a pivotal Phase II clinical trial in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) (NCT03589469 ). The U.S. Food and Drug Administration granted orphan drug designation to ADCT-402 for the treatment of DLBCL and mantle cell lymphoma.

About ADCT-301

ADCT-301 (camidanlumab tesirine) is an antibody drug conjugate (ADC) composed 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, ADCT-301 is internalized into the cell where enzymes release the PBD-based warhead. The intra-tumor release of its PBD warhead may cause bystander killing of neighboring tumor cells. In addition, the PBD warhead will trigger immunogenic cell death, which in turn will strengthen the immune response against tumor cells. ADCT-301 is being evaluated in ongoing Phase Ia/Ib clinical trials in patients with relapsed or refractory Hodgkin lymphoma and non-Hodgkin lymphoma (NCT02432235 ), as well as a Phase Ib clinical trial in solid tumors (NCT03621982 ).
