ADC Therapeutics Doses First Patients in Pivotal Phase 2 Clinical Trial of ADCT-301 in Patients with Relapsed or Refractory Hodgkin Lymphoma
EQS Group-News: ADC Therapeutics SA
/ Key word(s): Study
Trial to support anticipated BLA submission in 1H 2022
Alex Herrera, MD, Assistant Professor, Department of Hematology/Hematopoietic Cell Transplantation at City of Hope Medical Center and an investigator for the trial, said, "Approximately 15 to 25 percent of the 16,500 patients diagnosed with HL each year in the U.S. and Europe have relapsed or refractory HL. While advances have been made in the treatment of HL, a significant unmet medical need remains in the relapsed or refractory HL patient population, especially patients who have progressed following treatment with other novel agents. I believe ADCT-301 has the potential to fill this important medical need."
The primary objective of the Phase 2, multi-center, open-label, single-arm clinical trial is to evaluate the efficacy of ADCT-301 in patients with relapsed or refractory HL, measured by overall response rate based on the 2014 Lugano Classification Criteria. Patients with pathologically confirmed relapsed or refractory HL who have failed three prior lines of therapy, including brentuximab vedotin and a checkpoint inhibitor approved for HL such as nivolumab or pembrolizumab, are eligible for enrollment in the clinical trial.
Jay Feingold, MD, PhD, Senior Vice President, Chief Medical Officer and Head of Oncology Clinical Development at ADC Therapeutics, said, "In our large Phase 1 clinical trial, ADCT-301 demonstrated an overall response rate of 86.5 percent in patients with HL at the dose we are using in the pivotal Phase 2 clinical trial, with more than half of those being complete responses. We look forward to continuing the evaluation of ADCT-301 in this pivotal Phase 2 trial and, if successful, submitting a BLA to the FDA for accelerated approval of ADCT-301 for the treatment of relapsed or refractory HL in patients who have failed or were intolerant to brentuximab vedotin and a checkpoint inhibitor approved for HL."

ADCT-301 (camidanlumab tesirine) is an antibody drug conjugate (ADC) composed of a human monoclonal antibody that binds to CD25 (HuMax(R)-TAC, licensed from Genmab A/S), conjugated to the pyrrolobenzodiazepine (PBD) dimer payload tesirine. Once bound to a CD25-expressing tumor cell, ADCT-301 is internalized into the cell where enzymes release the PBD-based warhead killing the cell with an immunogenic cell death. The intra-tumoral release of its PBD warhead may also cause bystander killing of neighboring tumor cells. The ADC also depletes CD25-positive regulatory T cells in the tumor environment. All of these properties of ADCT-301 may enhance immune-mediated anti-tumor activity. ADCT-301 is being evaluated in a pivotal Phase 2 clinical trial in patients with relapsed or refractory Hodgkin lymphoma (NCT04052997), as well as ongoing Phase 1a/1b clinical trials in patients with relapsed or refractory Hodgkin lymphoma and non-Hodgkin lymphoma (NCT02432235) and a Phase 1b clinical trial in solid tumors (NCT03621982).
