NCT05608330

Brief Summary

PETRUSHKA is aimed at developing and subsequently testing a personalised approach to the pharmacological treatment of major depressive disorder in adults, which can be used in everyday NHS clinical settings. We have collected data from patients with major depressive disorder, obtained from diverse datasets, including randomised trials as well as real-world registries (registers that hold routinely collected NHS data from the UK). These data summarise the most reliable and most up-to-date scientific evidence about benefits and adverse effects of antidepressants for depression and have been used to inform the PETRUSHKA prediction model to produce individualised treatment recommendations. The prediction model underpins a web-based decision support tool (the PETRUSHKA tool) which incorporates the patient's and clinician's preferences in order to rank treatment options and tailor the treatment to each patient. This trial will recruit participants from the NHS within primary care in England and investigate whether the use of the PETRUSHKA tool is better than 'usual care' treatment in terms of adherence to antidepressant treatment, clinical response and quality of life, and its cost-effectiveness over a 6-months follow up.

Outcome Measures

Primary Outcomes (1)

  • To determine whether using the PETRUSHKA tool to "personalise" antidepressant treatment, results in an increased proportion of patients continuing the allocated treatment, compared to usual care.

    The number of participants who are still taking the allocated antidepressants after 8 weeks.

    8 Weeks

Secondary Outcomes (12)

  • Self-rated change in depressive symptoms from baseline

    Baseline, week 2, 4, 6, 8, 12, 16, 20, 24

  • Observer-rated change in depressive symptoms from baseline

    Baseline, week 2, 4, 6, 8, 12, 16, 20, 24

  • The number of participants who discontinue from treatment at 8 weeks due to any cause

    Week 8

  • The number of participants who discontinue from treatment at 24 weeks due to any cause

    Week 24

  • The number of participants who discontinue from treatment at 8 weeks due to adverse events

    Week 8

  • +7 more secondary outcomes

Study Arms (2)

PETRUSHKA tool

EXPERIMENTAL

The intervention is the PETRUSHKA web-based App (also called PETRUSHKA tool), a clinical decision-support system that incorporates a personalised evidence-based prediction model with individual patient preferences, to prescribe the best antidepressant to adults with depression

Other: PETRUSHKA tool

Usual Care

PLACEBO COMPARATOR

Routine care delivered in the NHS (i.e. selection of the antidepressant based primarily on the clinicians' judgement) termed 'usual care' in this study.

Other: Usual Care

Interventions

In the experimental arm, the PETRUSHKA tool will automatically select the antidepressants that have the best profile in terms of efficacy and acceptability for each individual participant (based on their baseline demographic and clinical characteristics) and then ask the participant to provide their preferences about common (and non-serious) adverse events. Based on patient's preferences and their individual characteristics, the PETRUSHKA tool will then identify the three best antidepressants for the participant. The clinician and the participant will be presented with an overall recommendation (in the format of a pictogram) showing how strongly each antidepressant is recommended for that individual patient. Via a shared decision-making process, the participant and the clinician will then agree on which antidepressant to choose from the shortlist.

PETRUSHKA tool

Any antidepressant prescribed by clinician based upon their clinical judgement.

Usual Care

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 18 - 74 years inclusive;

  • Diagnosis of arrhythmias (including Q-T prolongation, heart block), recent MI, poorly controlled epilepsy, acute porphyrias;
  • Require urgent mental care or admission (including suicidal intent/plans);
  • Concurrently enrolled in another investigational medicinal product (IMP) trial or an interventional trial about depression;
  • Participants who are currently pregnant, planning pregnancy or lactating;
  • Has a medical, social or other condition which, in the investigator's opinion , may make the participant unable to comply with all the trial requirements (e.g., terminal illness - motor neuron disease).
