• In the second, third, and fourth dose cohorts of monotherapy and combination arms comprising 26 patients, 18 patients (69%) achieved an objective response, including 12 patients (46%) that achieved a complete response, on Day 29 following a single dose of FT596. 
• 5 of 6 patients achieved an objective response, including four patients with complete response, with a single dose of FT596 at 900 million cells combined with rituximab.
• Nine of these 26 patients were previously treated with autologous CD19-targeted CAR T-cell therapy and, of these nine patients, six achieved an objective response (67%) on Day 29 following a single dose of FT596. 
• Ten patients continued in ongoing response, including three patients in ongoing complete response at least six months from initiation of treatment; two patients reached six months in complete response and subsequently had disease progression.
• One patient had disease progression before six months.
