Studie av effektivitet, säkerhet och tolerabilitet av AVP-786 som en tilläggsterapi hos patienter med allvarlig depressiv sjukdom med otillräckligt svar på antidepressiv behandling
En fas 2, multicenter, randomiserad, dubbelblind, placebokontrollerad studie för att bedöma effektiviteten, säkerheten och toleransen av AVP-786 (deuteriummodifierad dextrometorfanhydrobromid/kinidinsulfat) som en tilläggsterapi hos patienter med egentlig depression med en Otillräckligt svar på antidepressiv behandling
The objectives of this 10-week study are to evaluate the efficacy, safety, and tolerability of AVP 786 as an adjunctive therapy compared with placebo in patients with major depressive disorder (MDD) who have shown an inadequate response to standard antidepressant treatment. A secondary objective of this study is to assess the pharmacokinetics (PK) of AVP-786 and potential correlations with pharmacodynamic effects.

Detaljerad beskrivning
It is estimated that up to approximately 200 patients will participate in the study at approximately 30 enrolling centers in the US.
Eligible patients for this study must have MDD as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) criteria, and have shown an inadequate response to standard antidepressant treatment.
This is a multicenter, randomized, double-blind, placebo-controlled, study of 10 weeks duration.
Following screening procedures for assessment of inclusion and exclusion criteria, eligible patients will be randomized into the study. Study medication will be administered orally twice a day (BID) (1 capsule in the morning and 1 capsule in the evening, approximately 12 hours apart) throughout the treatment period.

Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (MGH ATRQ)
Tidsram: Visit 5 (Day 70) Week 10
|
The MGH ATRQ is given in this study to assess treatment resistance in depression. Participants are to provide information on the questionnaire about the dose level and duration for each medication that has been taken during their current episode/stage of depression. Participants are also to provide the medication that helped them the most and answer a question about the degree of improvement. |

16-item Quick Inventory of Depressive Symptomatology - Self Report (QIDS-SR16)
Tidsram: Visit 5 (Day 70) Week 10
|
The 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16) is a patient-reported questionnaire used to assess the severity of depressive symptoms over the previous 7 days. The questionnaire assesses sleep, mood, appetite/weight, concentration, self-perception, suicidal thoughts, interest, energy, and psychomotor changes. Each item is scored from 0 to 3, with higher scores indicating greater symptom severity. The total score is calculated using a standard algorithm that sums the highest-rated item within selected symptom domains and individual domain scores, resulting in a total score ranging from 0 to 27, with higher scores indicating more severe depressive symptoms. |

Clinical Global Impression of Severity of Illness (CGI-S)
Tidsram: Visit 5 (Day 70) Week 10
|
The CGI-S is clinician's assessment of the participant's illness at the time of the assessment. The CGI-S is scored according to the following 7-point scale, with a higher score indicating a higher severity of illness (0 = not assessed): 1 = normal, not at all ill, 2 = borderline mentally ill, 3 = mildly ill, 4 = moderately ill, 5 = markedly ill, 6 = severely ill, 7 = extremely ill. |

Clinical Global Impression of Change (CGI-C)
Tidsram: Visit 5 (Day 70) Week 10
|
The CGI-C is clinician's assessment of the participant's change in illness at the time of the assessment, using the following 7-point scale (0 = not assessed): 1 = Very much improved, 2 = Much improved, 3 = Minimally improved, 4 = No change, 5 = Minimally worse, 6 = Much worse, 7 = Very much worse. A lower score indicates an improvement in illness. |

EuroQOL 5 Dimension 5 Level (EQ-5D-5L)
Tidsram: Visit 5 (Day 70) Week 10
|
The EQ-5D-5L, a scale used to measure quality of life, is divided into 2 parts, the descriptive system and the visual analog scale (VAS), reported as separate scores. The descriptive system is divided into five categories: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. For each category, the participant selects the one statement that best describes their health on the day of assessment. Each category is scored on a 5-point scale(1=no problems to 5=extreme problems or inability to perform the activity) [e.g., for mobility: 1 = no problems walking and 5 = unable to walk]. Missing values for a given category are imputed with a value of 9 and are excluded from the summary for that category. Higher scores for each category= worse health condition. The VAS is a 0 (worst health you can imagine) to 100 (best health you can imagine) vertical scale, where the participant places an X on the scale where they feel their health is today and then writes the number. |

Patient Global Impression of Change (PGIC)
Tidsram: Visit 5 (Day 70) Week 10
|
The PGI-C asks the participant to rate their overall impression of change in their depression symptoms from the time of study entry to the present. The PGI-C is scored on a 7-point scale, where 1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse. Higher scores indicate worsening of depression symptoms. |

7-item Generalized Anxiety Disorder (GAD-7)
Tidsram: Visit 5 (Day 70) Week 10
|
The GAD-7 is a self-reported questionnaire used to assess symptoms of generalized anxiety disorder. It consists of 7 questions evaluating feelings of nervousness or anxiety, inability to stop or control worrying, excessive worrying, trouble relaxing, restlessness, irritability, and fear that something awful might happen. Each item is scored on a 4-point scale, where 0 = not at all, 1 = several days, 2 = more than half the days, and 3 = nearly every day. The scores for all seven items are summed to produce a total score ranging from 0 to 21, with higher scores indicating greater severity of anxiety symptoms. |
