Feasibility Trial of Pembrolizumab Plus Ultrasound-Induced Microbubble Cavitation in Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma
Thomas Jefferson University
Summary
This is a feasibility trial studying anti-PD-1 therapy (Pembrolizumab) among patients with R/M HNSCC, delivered with ultrasound-induced microbubble cavitation, with the goal of optimizing delivery of Pembrolizumab and tumor response to Pembrolizumab. Patients will undergo 3 infusions of Pembrolizumab plus Definity 3 weeks apart. Following each infusion, ultrasound will be directed at the primary tumor site to induce microbubble cavitation, with the goal of tumor sonoporation. The primary endpoints will be feasibility, measured based on successful recruitment of 6 participants within 1 year of initiating recruitment, with successful completion of trial procedures among at least 80 percent of patients. Secondary endpoints will include proportion of serious adverse events, clinical/radiographic response, overall survival, and progression-free survival.
Description
The proposed study is a feasibility trial of Pembrolizumab plus Definity Perflutren Lipid Microsphere (Lantheus Medical Imaging), followed by ultrasound-induced microbubble cavitation (UC), which will target patients with R/M HNSCC, for which Pembrolizumab is already indicated as standard of care treatment. Patients will undergo up to 3 cycles of therapy. Participants may continue study treatment for up to 3 cycles, 3 weeks apart, from the time of initiating treatment, with 3-month safety follow-up. Participant characteristics and endpoints will be summarized through appropriate descriptive s…
