BackgroundThe aim of the TAILOR trial is to investigate the effect of closely monitored tapering/discontinuation versus maintenance therapy with antipsychotic medication in patients with newly diagnosed schizophrenia or persistent delusional disorder and with minimum 3 months’ remission of psychotic symptoms.Methods and designTwo hundred and fifty patients will be included from the psychiatric early intervention program, OPUS, in two regions in Denmark. Inclusion criteria are: ICD-10 diagnoses schizophrenia (F20, except F20.6) or persistent delusional disorder (F22), minimum 3 months’ remission of psychotic symptoms and in treatment with antipsychotic medication (except clozapine). The patients will be randomized to maintenance therapy or tapering/discontinuation with antipsychotic medication in a 1-year intervention. The tapering/discontinuation group will be using a smartphone application to monitor early warning signs of psychotic relapse. Patients will be assessed at baseline, 1-, 2- and 5-year follow-up regarding psychotic and negative symptoms, side-effects of antipsychotic medication, social functioning, cognitive functioning, perceived health status, patient satisfaction, substance and alcohol use, sexual functioning and quality of life. The primary outcome will be remission of psychotic symptoms and no antipsychotic medication after 1 year. Secondary outcome measures will include: co-occurrence of remission of psychotic symptoms and 0–1-mg haloperidol equivalents of antipsychotic medication after 1-year intervention; antipsychotic dose; antipsychotic side effects; negative symptoms; social functioning; cognitive functioning; and patient satisfaction. Exploratory outcomes will include remission, clinical recovery, substance and alcohol use, sexual functioning, quality of life, self-beliefs of coping and user experience of support from health workers. Safety measures will include death, admissions to psychiatric hospital, severe self-harm and psychotic relapses.DiscussionThe TAILOR trial will contribute knowledge about the effect of tapering/discontinuation of antipsychotic medication in the early phases of schizophrenia and related disorders and the results may guide future clinical treatment regimens of antipsychotic treatment.Trial registrationEU Clinical Trials Register – EudraCT number: 2016-000565-23.

AimEvidence is insufficient regarding the consequences of discontinuing vs. maintaining antipsychotic medication in patients with first-episode schizophrenia. Our aim was to examine tapered discontinuation vs. maintenance treatment regarding remission of psychotic symptoms and impact on other areas.MethodsPatients included had a diagnosis of schizophrenia, were treated with antipsychotic medication, and were in remission of psychotic symptoms. Participants were randomized to tapered discontinuation or maintenance treatment with antipsychotic medication. Assessments were undertaken at baseline and after 1-year. The primary outcome was remission of psychotic symptoms without antipsychotic medication.ResultsThe trial was terminated due to insufficient recruitment. In total, 29 participants were included: 14 in the tapering/discontinuation group and 15 in the maintenance group. Adherence to maintenance treatment was poor. At 1-year follow-up, remission of psychotic symptoms without antipsychotic medication for 3 months was observed in five participants in the tapering/discontinuation group and two in the maintenance group.ConclusionDue to insufficient recruitment this study does not provide a conclusion on whether unfavorable outcomes or advantages follow tapering of antipsychotic medication. Recruitment and adherence to maintenance treatment encountered obstacles. Based on experiences from this trial, we discussed alternative study designs as consistent evidence is still needed on whether to continue or discontinue antipsychotic medication in remitted patients with first-episode schizophrenia.Clinical trial registrationhttps://www.clinicaltrialsregister.eu/ctr-search/trial/2016-000565-23/DK, EU Clinical Trials Register—EudraCT no. 2016–000565–23.

Background and AimsWeight gain is a major adverse effect of antipsychotic medication, negatively affecting physical and mental well-being. The objective of this study was to explore if dose reduction, discontinuation, switch to a partial agonist, or switch from polypharmacy to monotherapy will lead to weight loss.MethodsControlled and uncontrolled studies reporting the effects of discontinuation, dose reduction, switch to a partial agonist, or switch from polypharmacy to monotherapy on weight were included. Primary outcome was difference in weight compared to maintenance groups based on controlled studies. Secondary outcome was change in weight from initiation of one of the included interventions until follow-up in a pre-post analysis.ResultsWe identified 40 randomized controlled trials and 15 uncontrolled studies including 12,279 individuals. The effect of the interventions, i.e. dose reduction, drug discontinuation, or switch to a partial agonis, reduced the weight with 1.5 kg (95% CI −2.03 to −0.98; P < 0.001) compared to maintenance treatment. The weight change from pre to post was a reduction of 1.13 kg (95% CI −1.36 to −0.90; P < 0.001).ConclusionWe found a significant but small reduction in weight, suggesting that antipsychotic-induced weight gain can be reversed to some degree. Only a few studies were designed to address the question as primary outcome, which limits the generalizability of our findings.
