ASH 2017

ZUMA-1 is a pivotal, multicenter trial of axicabtagene ciloleucel (axi-cel), an autologous anti-CD19 chimeric antigen receptor (CAR) T-cell therapy, for the treatment of patients with refractory, aggressive non-Hodgkin lymphoma (NHL). The objective response rate (ORR) was 82% with a 54% rate of complete response (CR), and 44% of responses were ongoing at the time of the primary analysis. Grade ≥3 cytokine release syndrome (CRS) and neurologic events (NEs) occurred in 13% and 28% of patients, respectively.

Brentuximab vedotin (BV), an antibody drug conjugate, selectively delivers the antitubulin agent, monomethyl auristatin E, to CD30+ cells. In a multicenter phase 2 trial in patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL), BV showed an overall response rate (ORR) of 75%, a complete response (CR) rate of 34%, and a median duration of response (DOR) of 6.7 months.

Atlanta, GA—More than 25,000 attendees converged on Atlanta during the middle of a rare winter snowstorm to attend ASH 2017, which featured nearly 5000 scientific abstract presentations ranging from cutting-edge advances in gene therapy and personalized medicine to practice-changing discoveries in immunotherapies.

Combination treatment with nivolumab plus azacitidine produced encouraging response rates in patients with relapsed or refractory (R/R) acute myeloid leukemia (AML) with poor-risk features, and in elderly patients as frontline therapy.

A phase 1 dose-escalation study of FLX925, a dual FLT3 and CDK4/6 inhibitor, showed modest antileukemic activity in adult patients with relapsed or refractory acute myeloid leukemia (AML).

An analysis of response and survival outcomes from the phase 1/2 AG221-C-001 study showed that continued treatment with enasidenib resulted in improved survival and response times in patients with mutant-IDH2 relapsed or refractory (R/R) acute myeloid leukemia (AML).

The results of the current phase 1b/2 study showed that the combination of azacitidine plus lirilumab was well-tolerated in heavily pretreated patients with relapsed acute myeloid leukemia (AML) and poor-risk disease features.

An updated safety and efficacy analysis of a phase 1b study demonstrated a promising benefit–risk profile with the combination of the BCL-2 inhibitor venetoclax with either decitabine or azacitidine in elderly, treatment-naïve patients with acute myeloid leukemia (AML) who are not candidates for intensive standard induction therapy.

The results of a post-hoc analysis of the RATIFY trial suggest that midostaurin decreases the cumulative incidence of relapse (CIR) in patients with FLT3 mutation–positive, newly diagnosed acute myeloid leukemia (AML), with no negative impact on survival.

This analysis showed that ivosidenib-treated patients with IDH1-mutated (mIDH1), relapsed/refractory, and untreated acute myeloid leukemia (AML) whose best response is a complete remission (CR) or CR with partial hematologic recovery achieve mIDH1 clearance ≤0.04%.
