E.5 End points |
E.5.1 | Primary end point(s) |
The primary objective of this trial is to assess the feasibility of a future randomized controlled trial (RCT) on the efficacy of oral S-ketamine in decreasing depression and demoralization severity in patients with advanced, non-curable cancer.
• Feasibility will be judged based on safety, tolerability and acceptability as indicated by (1) greater than 80% of significant adverse effects resolving within 120 minutes of each administration, (2) less than 20% dropout rate secondary to adverse effects and (3) feedback from participants regarding treatment sessions and assessments.
• Efficacy is defined as a clinically important reduction of symptoms (defined as 50% reduction in HDRS17 score and/or 50% reduction in DS score) in at least 30% of participants who commenced treatment.
|
Eerste aanwijzingen voor effectiviteit van de interventie, gedefinieerd als een klinisch waardevolle vermindering van depressie en/of demoralisatie bij ten minste 30% van de deelnemers die gestart zijn met de behandeling. Haalbaarheid van de interventie wordt beoordeeld op basis van veiligheid, tolerantie en aanvaardbaarheid, zoals aangetoond door (1) meer dan 80% van de belangrijke bijwerkingen verdwijnen binnen 120 minuten na elke ketaminetoediening, (2) minder dan 20% van de deelnemers stopt met deelname door bijwerkingen, en (3) feedback van de deelnemers over de behandel- en onderzoeksessies en assessments. |

|
E.5.2 | Secondary end point(s) |
The secondary objectives of this trial, as described in chapter 2, will be measured by the following secondary study endpoints:
• Decrease in self-reported depression severity, as expressed by a decrease in total score on the Beck Depression Inventory (BDI);
• Changes in patients’ quality of life, as expressed by a decrease in total score on the McGill Quality of Life Questionnaire (MQOL);
• Decrease in anxiety, expressed as a decrease in total score on the:
- Hospital Anxiety and Depression Scale (HADS) anxiety subscale;
- Death and Dying Distress Scale (DADDS);
• Subjective experiences of participants during the trial, as assessed by in-depth, semi-structured interviews.
|
• Vermindering in gerapporteerde ernst van depressie, zoals uitgedrukt door een vermindering in de totale score op de Beck Depression Inventory (BDI);
• Verandering (verbetering) in de kwaliteit van leven, zoals uitgedrukt in een vermindering van de totale score op de McGill Quality of Life Questionnaire (MQOL);
• Vermindering van angst, zoals uitgedrukt in een vermindering van de totale score op de Hospital Anxiety and Depression Scale (HADS) angst subschaal en de Death and Dying Distress Scale (DADDS);
• Subjectieve ervaringen van deelnemers tijdens het onderzoek, welke worden uitgevraagd door middel van semigestructureerde diepte-interviews. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
The end of the study will be 12 months after the first inclusion OR after the 10th inclusion has completed the study.
The study will be terminated prematurely in case of change in the risk profile of ketamine, making it necessary to re-assess the use of the investigational product. This means that the study is terminated if severe adverse events occur that require medical attention, and that to a certain degree of probability are a harmful and undesirable reaction to ketamine. |
Het einde van de studie is 12 maanden na de eerste inclusie OF nadat de 10e inclusie de studie heeft afgerond.
De studie kan prematuur worden beëindigd in het geval dat er een verandering in het risicoprofiel van ketamine optreedt, wat het nodig maakt om een her-evaluatie te doen van het middel. Dat betekent dat de studie wordt beëindigd als er serieuze bijwerkingen optreden die medische aandacht vragen, en die mogelijk schadelijk en onwenselijk zijn. |
