23 patients with relapsed or refractory Hodgkin’s lymphoma that had already been heavily treated receivednivolumab (at a dose of 3 mg per kilogram of body weight –hu monoclonal IgtG4 Ab against PD-1) every 2weeks until they had a complete response, tumor progression, or excessive toxic effects.

Study objectives were measurement of safety and efficacy and assessment of the PDL1 and PDL2 (alsocalled CD274 and PDCD1LG2, respectively) loci and PD-L1 and PD-L2 protein expression.

On the same day as the approval, the FDA expanded the indication for tocilizumab, a monoclonal antibodyto treat CAR T-cell–induced, severe or life-threatening CRS in patients ≥2 years of age. In clinical trials ofpatients treated with CAR T cells, 69 percent of patients had complete resolution of CRS within two weeksfollowing one or two doses of tocilizumab.Sources: U.S. Food and Drug Administration news release, August 30, 2017; Novartis news release, August30, 2017.

The U.S. Food and Drug Administration (FDA) approved the chimeric antigen receptor (CAR) T-cell therapy tisagenlecleucel for the treatment of pediatric and young adult patients with B-cell precursor acute lymphocytic leukemia (ALL) that is refractory or in second or later relapse. This is the first gene therapy available in the U.S. and is “ushering in a new approach to the treatment of cancer and other serious and life-threatening diseases,” the FDA said.

First-in-class therapy showed an 83% (52/63) overallremission rate in B-cell ALL patient population with limitedtreatment options and historically poor outcomes

Approval was based on data from the multicenter ZUMA-1 trial, which included 111 patients (median age = 58 years; range =23-76 years) with previously treated DLBCL, primary mediastinal large B-cell lymphoma, or transformed follicular lymphomafrom 22 institutions.

January 27, 2017, 101 patients (91%) had received axicabtagene ciloleucel 2×106 cells/kg, following conditioning with low-dose cytarabine and fludarabine.

ORR=72%, CR = 51% (95% CI 41-62).

Median duration of response was 8.1 months; Six-month OS rate was 80 percent.The most common grade ≥3 treatment-related adverse events included neutropenia (66%), leukopenia (44%), anemia (43%),febrile neutropenia (31%), thrombocytopenia, (24%), and encephalopathy (21%).The drug carries a boxed warning for cytokine release syndrome (CRS) and neurologic events, and it was approved with aRisk Evaluation and Mitigation Strategy. In the study, 13 percent and 28 percent of patients experienced severe grade ≥3 CRSand neurologic events, respectively. Fatal cases of CRS and neurologic toxicity occurred.In the subset of 70 patients who experienced CRS or neurologic events, 43 required treatment with tocilizumab and 27required treatment with tocilizumab and steroids, but the treatments did not decrease the efficacy of axicabtagene ciloleucel(ORR = 84% and 78%, respectively).

Axicabtagene ciloleucelapproved for adult patients whose disease failed torespond to at least two prior treatments, as well as forthe following indications:• diffuse large B-cell lymphoma (DLBCL)• primary mediastinal large B-cell lymphoma• high grade B-cell lymphoma• DLBCL arising from follicular lymphoma
