Findings from the study were presented by Nicholas Short, M.D., assistant professor of Leukemia, Dec. 9 at the 61st American Society of Hematology Annual Meeting & Exposition in Orlando, Fla. The study was led by Elias Jabbour, M.D., professor of Leukemia.
“This study demonstrated that reduced-intensity chemotherapy, when combined with INO, resulted in a 98% response rate and three-year survival rate of 54%,” said Short. “Ninety-five percent of all patients who responded showed no detectable minimal residual disease, which is an important endpoint in ALL therapy that has been shown to correlate with reduced risk of relapse and better long-term survival.”
Previous international studies, both led by MD Anderson investigators, showed that blinatumomab and INO given as single agents were more effective than standard chemotherapy for treatment of advanced ALL, and are now being added as frontline treatment options.
The study treated 64 patients with a median age of 68 years. Among the 59 evaluable patients, 58 or 98% of them achieved a complete response. With a median follow up of 37 months, the three-year overall survival rate was 54%, with 30 patients in complete remission with no signs of minimal residual disease.
“The outcomes of patients who did or did not received blinatumomab were similar, although we will need more follow-up to determine whether the addition of blinatumomab will improve outcomes in the long-term,” said Short. “This trial resulted in significantly higher three-year survival rates compared to the 32% survival rates observed in a similar historical cohort of older patients treated with intensive chemotherapy. These findings may represent a new standard of care in this older population.”
The study was funded by Pfizer and Amgen. Short reports honoraria from Amgen, and he is funded by the ASH Junior Faculty Scholar Award in Clinical Research.
