Abstract

Aripiprazole 2-month ready-to-use 960 mg (Ari 2MRTU 960) is a new long-acting injectable antipsychotic formulation for administration every 2 months. A randomized, open-label, 32-week trial evaluated the safety, tolerability, and pharmacokinetics of Ari 2MRTU 960 in clinically stable adults with schizophrenia or bipolar I disorder (per criteria). This secondary analysis evaluated the safety and efficacy of Ari 2MRTU 960 in the subpopulation of patients with schizophrenia. Patients were randomized to receive Ari 2MRTU 960 every 56 ± 2 days (4 injections scheduled) or aripiprazole once-monthly 400 mg (AOM 400) every 28 ± 2 days (8 injections scheduled). Data were collected during August 2019-July 2020 across 16 US sites. Primary endpoints included safety and tolerability, evaluated throughout. Secondary endpoints for efficacy in patients with schizophrenia included change from baseline at week 32 in Positive and Negative Syndrome Scale, Clinical Global Impression - Severity, and Subjective Well-being under Neuroleptic Treatment - Short Form scores, along with Clinical Global Impression - Improvement at week 32. Patients with schizophrenia were randomized to Ari 2MRTU 960 (n = 92) or AOM 400 (n = 93). The incidence of treatment-emergent adverse events (TEAEs) was similar between Ari 2MRTU 960 (66.3%) and AOM 400 (63.4%). The most frequently reported TEAE was increased weight (Ari 2MRTU 960: 21.7%; AOM 400: 18.3%). Patients in both treatment groups remained clinically stable throughout, with minimal change from baseline observed in efficacy parameters at week 32. Ari 2MRTU 960 was well tolerated in clinically stable patients with schizophrenia, with efficacy similar to AOM 400. ClinicalTrials.gov identifier: NCT04030143.
