Pipamperone/Citalopram (PNB01) Versus Citalopram (CIT) and Versus Pipamperone (PIP) in Major Depressive Disorder (MDD)
Pipamperone/Citalopram (PNB01) Versus Citalopram (CIT) and Versus Pipamperone (PIP) in the Treatment of Moderate to Severe Major Depressive Disorder (MDD): a Randomized, Double-blind Phase III Study of 10 Weeks

The overall objective of this trial is to demonstrate clinically relevant superior antidepressant efficacy of the fixed dose combination PNB01 (low dose pipamperone and citalopram) over reference antidepressant treatment with citalopram alone, and a low dose of psychoactive pipamperone alone in patients with moderate to severe Major Depressive Disorder.

This study was specifically designed to assess patient related outcome (PRO) parameters using an Interactive Voice Response System (IVRS) via telephone.

This is an international, double-blind, centrally randomized (stratified), multicenter study in 555 patients suffering from moderate to severe MDD in up to 40 sites in the USA, Germany and Canada. Eligible out-patients will be treated once daily (QD) with a fixed dose of either PNB01 (PIP 15 mg / CIT 20 mg (Week 1) - PIP 15 mg / CIT 40 mg (Week 2-10)), CIT alone (CIT 20 mg (Week 1) - CIT 40 mg (Week 2-10) or PIP 15 mg alone (Week 1-10) in a 1:1:1 ratio in a double-blind fashion for 10 weeks. Study visits will be conducted 1, 2, 3, 4, 6, 8 and 10 weeks after study treatment initiation. Possible withdrawal effects will be assessed 1 week after study treatment withdrawal.

A blood sample for pharmacokinetic analysis will be collected when drawing blood for routine biochemistry. Patients who provided written informed consent to participate to the study will be asked to provide their consent to participate also to the non-mandatory pharmacogenetic study.

Patient related outcomes will be collected electronically (ePRO) at study visits prior to visiting the investigator by using an Interactive Voice Response System (IVRS) via telephone. Patients wishing or choosing to discontinue the study treatment prematurely will be encouraged to continue to provide their scores, safety data and medications taken, up to the scheduled study end, by telephone.

Inclusion Criteria:

  1. Patient is informed and given ample time and opportunity to think about her/his participation and has given her/his written informed consent.

  3. Patient is male or female, aged ≥ 18 years.
  4. Patient has MDD according to the DSM IV-R criteria with an existence of depressed mood (DSM-IV-R Crit. A1) and loss of interest/anhedonia (DSM-IV-R Crit. A2) as confirmed by the MINI, lasting for at least 4 weeks and no longer than 18 months (78 weeks) for the current episode, and causing significant functional impairment (DSM-IV-R MDD C- criterion).
  5. CGI-S rating of at least 4 and a minimum MADRS total score of 26 using IVRS ePRO at Baseline.

Exclusion Criteria:

  1. Patient is pregnant, nursing, or is a woman of child-bearing potential who is not surgically sterile, 2 years postmenopausal, or who does not consistently use 2 combined effective methods of contraception (including at least 1 barrier method), unless sexually abstinent.
  2. Existence of Mood Disorder with psychotic features and/or high suicidality risk, as confirmed by MINI.
  3. Concomitant diagnosis of any additional primary Axis I disorder and presence of any of the following co-morbid disorders: (Hypo)manic episode, Panic Disorder (limited symptom attacks allowed), Obsessive Compulsive Disorder, Post-traumatic Stress Disorder, Alcohol dependence, any other Substance abuse and/or dependence, Psychotic Disorder, Eating Disorder, or General Anxiety Disorder, as confirmed by MINI.
  4. Concomitant diagnosis of any primary Axis II disorder.
  5. Patient is hospitalized.
