Impact of cytopenias and early versus late treatment with ruxolitinib in patients with steroid-refractory acute or chronic graft-versus-host disease
Abstract: REACH2 and REACH3 were randomized, multicenter, open-label phase 3 studies comparing the selective Janus kinase (JAK)1/JAK2 inhibitor ruxolitinib versus investigators’ choice of best available therapy (BAT) in steroid-refractory (SR) acute (REACH2) or chronic (REACH3) graft-versus-host disease (aGVHD/cGVHD). Moderate-severe aGVHD/cGVHD can progress rapidly; thus, key clinical considerations driving management of patients with SR-aGVHD/SR-cGVHD are prompt treatment initiation and concomitant cytopenias. These post hoc analyses of REACH2/REACH3 describe the impact of timing of treatment initiation after SR-aGVHD/SR-cGVHD diagnosis and development of concomitant cytopenias on treatment outcomes. Ruxolitinib initiation within 3 days from SR-aGVHD diagnosis yielded an extended duration of response and higher Day 28 complete response rates compared with initiation ≥7 days after SR-aGVHD diagnosis (median 178 vs 167 days and 36.6% vs 25.0%, respectively). For patients with SR-cGVHD, Week 24 overall response was not impacted by time to treatment (54.5% vs 42.6% for <14 vs >28 days). Clinically relevant cytopenias were manageable, allowing for maintenance of dose intensity (median 20 mg/d), and did not impact the favorable efficacy outcomes from ruxolitinib treatment. This analysis highlights the practical importance of considering earlier ruxolitinib initiation after SR diagnosis in GVHD and the benefits of ruxolitinib treatment compared with BAT even for patients with cytopenias
