Brief Summary: The primary objective of the present study is to examine whether the combination of the antidepressant duloxetine and chronotherapeutic methods including sleep deprivation light therapy and maintaining a regular sleep-wake rhythm in patient with major depression will induce an immediate improvement from depression and whether this antidepressive effect will be maintained in the long term 29 weeks Patient will be randomised to the above mentioned treatment or to an active group receiving exercise
Detailed Description: Protocol synopsis

Background

The Psychiatric Research Unit at Frederiksborg General Hospital with professor Per Bech as the driving force has been working with sleep in relation to affective disorders for many years During the last 4 years we have performed and been involved in several light therapy studies in depression both in seasonal affective disorder SAD with light as an augmentation strategy in nonseasonal depression in post-stroke depression and in Tourettes syndrome

In relation to the dissemination of results from Klaus Martinys PhD thesis on bright light therapy as an augmenting strategy in major depression our research unit has achieved close collaboration with some of the worlds leading experts in chronotherapeutics Professor Anna Wirz-Justice in Basel Switzerland Franscesco Benedetti in Milano Italy Michael Terman in New York Mathias Berger in Freiburg Germany and Joseph Wu at the University of California Irvine The basic idea of the present study comes from this group which over many years has performed and reported clinical studies in chronotherapeutics We hope that our research unit will be able to conduct this study as required in a large patient sample and under the guidance of this group

The study will fulfill the research units ambition to investigate antidepressive treatment algorithms with the propensity to lead to an earlier and sustained onset of action and a higher remission rate Remission from depression does not only restore the patients normal social functioning but also reduces the risk of recurrence of depression To attain this goal we regard the combination of new and powerful antidepressive drugs and non-pharmacological therapies most interesting and promising This study has full support from the hospital administration who welcomes the active involvement of the nursing staff in the chronotherapeutic part

The present study incorporates the combination of duloxetine and chronotherapeutics sleep deprivation sleep phase advance and light therapy

Duloxetine is a new dual action antidepressant drug that has shown an early onset of action and a high remission rate with acceptable side effects It is thus a promising drug for new studies

Chronotherapeutic approaches such as total or partial sleep deprivation phase advance of the sleep-wake cycle and light therapy have been investigated over the last thirty years

Total or partial sleep deprivation in the second half of the night and phase advance of the sleep-wake cycle have shown to have rapid and profound effects on depressed mood in all diagnostic subgroups Sleep deprivation attains an immediate response in around 60 of the cases and smaller reported studies using combinations of sleep deprivation with lithium antidepressant drugs pindolol sleep phase advance or morning light therapy have indicated that the response after initial sleep deprivation can be maintained Light treatment has become an accepted and effective treatment of seasonal affective disorder SAD and recent studies have document accelerated and augmented response in non-seasonal and even in chronic depressionas adjunctive treatment to medication

The combination of the effect of chronotherapeutics and new powerful antidepressant drugs thus is a very interesting and promising approach While light treatment is widely used sleep deprivation and sleep phase advance are therapies that are in need of studies with sufficient numbers of patients to evaluate their applicability and efficacy

Objectives

Duloxetine a new dual action drug has shown promising efficacy with an early onset of action and a high remission rate both in short- and long-term treatment Thus Raskin found an impressive remission rate of 508 after six weeks and 818 after 52 weeks of treatment The primary objective of the present study is to examine whether the combination of duloxetine and chronotherapeutic methods induces higher remission rates at an earlier time point and obtains a 50 percent remission rate after three weeks of treatment

Study design

The study will be a randomised controlled semi-blind rater-blind trial with a fixed dosage trial length of nine weeks Within this nine weeks period study drugs will be given at a dose of 60 mg duloxetine Patients will be randomized and start medication with duloxetine one week before starting the chronotherapeutic intervention This is a precaution not to cause any distress in patients as could be expected with new possible side-effects and the chronotherapeutic intervention introduced at the same time The following chronotherapeutic intervention covers one week seven days where patients will be admitted to an open ward If improved sufficiently patients can be discharged at this time point

Subsequently patients will be seen monthly in an uncontrolled follow-up period ending with a last visit at 6 month after inclusion into the study In this follow-up period starting from week nine patients will have the opportunity to alter dosage of study drug or to shift into other medication The only intervention in this follow up period will be to encourage the patients to keep the daily time structure as instructed during their admittance to the ward

Patients randomised to group A will be treated with a combination of duloxetine 60 mg per day for 29 weeks and a chronotherapeutic intervention of one weeks duration see below Patients randomised to group B will be treated with duloxetine in a dose of 60 mg per day for 29 weeks and individual exercise instructed by a physiotherapist Patients will be informed that the two intervention groups are based on different time-structuring regimes The placebo condition has been chosen to secure an similar expectancy rate in the two treatment conditions

Group A Duloxetine treatment with 60 mg per day for 29 weeks plus chronotherapeutic intervention of 1 week duration

Duloxetine dosage will be 60 mg daily with the possibility of increasing dosage to 90 or 120 mg at week nine for patients with incomplete response
Chronotherapeutic intervention

1 Light treatment Light treatment will be given with 10000 lux for 1 hour individually timed according to the MEQ score
2 Sleep deprivation and sleep phase advance Sleep will be scheduled as shown below

Day one to two Total sleep deprivation I
Day two to three from 9 pm to 7 am Sleep-phase-advance I
Day three to four Total sleep deprivation II
Day four to five from 9 pm to 7 am Sleep phase advance II
Day five to six Total sleep deprivation III
Day six to seven from 9 pm to 7 am Sleep phase advance III

Group B Duloxetine treatment with 60 mg per day for nine weeks plus chronotherapeutic intervention with moderate time structure and exercise of 1 weeks duration

Duloxetine dosage will be 60 mg daily with the possibility of increasing dosage to 90 or 120 mg at week nine for patients with incomplete response

From day seven and on sleep is regulated according to two rules

1 Not taking naps in the daytime
2 Getting out of bed by 8 am at the latest

Concomitant medication

Oxazepam is allowed for severe agitation and sleep disturbances except at days of sleep deprivation in daily doses as mentioned earlier

Psychometrics

The diagnosis of major depression will be made by the Mini International Neuropsychiatric Interview MINI Severity of depression will be assessed by weekly ratings using the interview-based Hamilton Depression Rating scales 17 and 6 items versions Bech et al 2000 and the newly developed 6 item self-assessment Hamilton scale Patients will fill in the Global Rating Scale Preskorn daily Side effects will be monitored weekly by the UKU scale At baseline the Morningness Eveningness Questionnaire MEQ will be used to calculate the individual timing of light

Time line

The study starts in September 2005 The inclusion period is 2 years and data will be published in a 6 months period thereafter

Efficacy measures

Primary outcome criteria will be response and remission Secondary outcome criteria will be the mean of weekly Hamilton ratings 17-items and 6-items versions

Tertiary outcome criterion will be the time until discharge

Regulations

The study will follow the Good Clinical Practice Guidelines and has obtained approval from the local ethical committee the Danish Data Protection Agency and the Danish Medicines Agency Patients will sign informed consent forms after written and oral descriptions of the study
