CAMBRIDGE, Mass.--()--bluebird bio, Inc. (Nasdaq: BLUE), a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic diseases and T cell-based immunotherapies for cancer, announced that updated interim data from its study of bb2121, the company’s anti-BCMA CAR T cell therapy will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, Illinois. bb2121 is currently being studied in a Phase 1 trial in patients with relapsed/refractory multiple myeloma.

“This past November we presented the initial clinical data from the first three dosing cohorts in this ongoing Phase 1 study of bb2121 in patients with relapsed/refractory multiple myeloma. At ASCO in June, we look forward to presenting data on those same patients with longer follow-up, as well as safety and efficacy data on an additional 9 patients treated subsequently.” said David Davidson, M.D., chief medical officer, bluebird bio. “These data will advance our understanding of the bb2121 risk-benefit profile and inform planning with our partners at Celgene for the dose expansion cohort of this study, and the design of a potential pivotal study.”
