era of personalized cancer therapy.”
Yescarta will be manufactured in Kite’s state-of-the-art commercial manufacturing facility in El Segundo, California. In the ZUMA-1 pivotal trial, Kite demonstrated a 99 percent manufacturing success rate with a median manufacturing turnaround time of 17 days, which is important to patients given the potential for rapid disease progression in this population.
Yescarta has been granted Priority Medicines (PRIME) regulatory support for DLBCL in the European Union. A Marketing Authorization Application (MAA) for axicabtagene ciloleucel is currently under review with the European Medicines Agency (EMA) and potential approval is expected in the first half of 2018.
Yescarta (axicabtagene ciloleucel) Pivotal Trial Results
The approval of Yescarta is supported by data from the ZUMA-1 pivotal trial. In this study, 72 percent of patients treated with a single infusion of Yescarta (n=101) responded to therapy (overall response rate) including 51 percent of patients who had no detectable cancer remaining (complete remission; 95% CI: 41, 62). At a median follow-up of 7.9 months, patients who had achieved a complete remission had not reached the estimated median duration of response (95% CI: 8.1 months, not estimable [NE]).
In the study, 13 percent of patients experienced grade 3 or higher cytokine release syndrome (CRS) and 31 percent experienced neurologic toxicities. The most common (≥ 10%) Grade 3 or higher reactions include febrile neutropenia, fever, CRS, encephalopathy, infections-pathogen unspecified, hypotension, hypoxia and lung infections. Serious adverse reactions occurred in 52% of patients and included CRS, neurologic toxicity, prolonged cytopenias (including neutropenia, thrombocytopenia and anemia), and serious infections. Fatal cases of CRS and neurologic toxicity occurred. FDA approved Yescarta with a Risk eva luation and Mitigation Strategy.

IMPORTANT SAFETY INFORMATION
BOXED WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITIES
•Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving Yescarta. Do not administer Yescarta to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.
•Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving Yescarta, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with Yescarta. Provide supportive care and/or corticosteroids as needed.
•Yescarta is available only through a restricted program under a Risk eva luation and Mitigation Strategy (REMS) called the Yescarta REMS.
