ADC Therapeutics SA (NYSE: ADCT), a commercial-stage biotechnology company leading the development of novel antibody drug conjugates (ADCs) to treat hematological malignancies and solid tumors, announced today that updated interim results from the ongoing pivotal Phase 2 clinical trial of camidanlumab tesirine (Cami) in patients with relapsed or refractory Hodgkin lymphoma were presented in an oral presentation (Abstract 075) at the 16th Annual International Conference on Malignant Lymphoma (ICML). The pivotal Phase 2 study is intended to support the submission of a Biologics License Application.
“The interim results from our ongoing pivotal Phase 2 trial of Cami as a single agent for patients with relapsed or refractory Hodgkin lymphoma demonstrate that a significant number of patients experience long-lasting treatment effects,” said Jay Feingold, MD, PhD, Senior Vice President and Chief Medical Officer of ADC Therapeutics. “In Phase 2, we used the optimal Phase 1 dosing schedule based on activity and tolerability, and we are encouraged by the interim data that show the median duration of response has not been reached. We also note that the incidence of GBS in Phase 2 is consistent with Phase 1. We look forward to providing future updates on this pivotal program as the overall response rate and duration of response data continue to mature.”
Cami is being evaluated in a multicenter, open-label, single-arm Phase 2 clinical trial in 117 patients with relapsed or refractory Hodgkin lymphoma who have received ≥3 prior lines of treatment (≥2 lines if ineligible for hematopoietic stem cell transplantation, HSCT), including prior treatment with brentuximab vedotin and a checkpoint inhibitor. The interim data cut includes 101 evaluable patients who had been in the study a median of 5.1 months. Patients were heavily pretreated with a median of 6 prior lines of systemic therapy.
Key data presented at ICML by Pier Luigi Zinzani, MD, PhD, IRCCS Azienda Ospedaliero-Universitaria di Bologna Istituto di Ematologia "Seràgnoli", and Dipartimento di Medicina Specialistica, Diagnostica e Sperimentale Università di Bologna, Bologna, Italy, include:
“Patients with relapsed or refractory Hodgkin lymphoma who have failed several lines of previous therapy such as brentuximab vedotin and PD-1 blockade have limited treatment options,” said Dr. Zinzani. “The antitumor activity and safety profile of Cami continues to demonstrate that this novel CD25-targeted ADC has the potential to address the unmet need in heavily pre-treated patients.”
