BACKGROUND: Older, compared with younger, patients with treatment-resistant depression (TRD) typically have lower response and remission rates with poorer tolerability to antidepressant treatment. This post-hoc analysis compared outcomes following treatment with esketamine nasal spray (ESK) between younger (18-64 years) and older (≥65 years) patients with TRD.
METHODS: SUSTAIN-2, an up to 1-year open-label safety and efficacy study of ESK plus an oral antidepressant, included patients with TRD either directly enrolled (≥18-year) or transferred from a phase 3 double-blind study, TRANSFORM-3 (≥65-year). Patients were treated in two phases: 4-week induction and 48-week optimization/maintenance.
RESULTS: Younger (n = 624) and older (n = 178) patients had similar baseline characteristics except for hypertension history (21.5% versus 48.3%, respectively). Patients (younger versus older) had similar mean baseline Montgomery-Åsberg Depression Rating Scale (MADRS) total scores and mean (SD) reductions in MADRS total scores for induction (-18.0 [7.19] versus -18.1 [9.37]; p = 0.492 [t = 0.69, df = 701]) and optimization/maintenance (week 12) (-19.9 [7.03] versus -22.2 [9.50]; p = 0.265 [t = -1.12, df = 3470]) phases. Treatment-emergent adverse events (TEAEs) reported in younger versus older patients, respectively, were: induction, 86.1% versus 74.8%; optimization/maintenance, 86.8% versus 81.0%; serious TEAEs: induction, 2.2% versus 1.9%; optimization/maintenance, 6.7% versus 4.8%; TEAEs of increased blood pressure: induction, 6.9% versus 6.5%; optimization/maintenance, 7.1% versus 9.5%; and falls: induction, 0.3% versus 0.6%; optimization/maintenance, 0.2% versus 0.8%. Cognitive tests did not show clinically meaningful differences between the age groups.
CONCLUSIONS: Although limited by the open-label design of SUSTAIN-2, this post-hoc analysis showed generally comparable improvement in depression between ESK-treated younger and older adult patients with TRD, with consistent safety outcomes.
