Teclistamab, a bispecific IgG4 antibody, was well-tolerated and showed encouraging efficacy with durable, deepening responses in heavily-pretreated, relapse or refractory patients with multiple myeloma, Amrita Y. Krishnan, MD, FACP, told Healio in a video interview.
The overall response rate in the 40 patients treated at the recommended phase 2 dose was 65%. Krishnan, director of Judy and Bernard Briskin Multiple Myeloma Center and professor of hematology/hematopoietic cell transplantation at City of Hope Cancer Center, presented the phase 1 data at the virtual ASCO Annual Meeting.
“We didn’t just see responses, but deep responses, with 58% of patients getting very good partial responses,” Krishnan said.
Krishnan added that it was “encouraging” to see not only a high response rate and deep responses, but also that the responses appear durable.
“My abstract showed very encouraging results as to the safety, efficacy and tolerability of teclistamab,” she said.
