"Data from the abstract on the Phase 2 study of ZYNLONTA combined with rituximab in patients with high-risk relapsed or refractory follicular lymphoma demonstrated a robust response among the 35 evaluable patients, with an overall response rate at week 12 of 97.1%," said Mohamed Zaki, MD, PhD, Chief Medical Officer of ADC Therapeutics. "All complete metabolic responses were maintained, with 4 of the 10 partial metabolic responses improving at week 21 for a best complete metabolic response rate of 80%."

"For relapsed or refractory marginal zone lymphoma, the abstract provides an update on ZYNLONTA as a single-agent treatment. As of the abstract submission date, the overall response rate was 85% with a complete response rate of 75% among the 20 evaluable patients," continued Dr. Zaki. "In both studies, safety was consistent with the known ZYNLONTA profile. We look forward to further updates at ASH."
