Duration of Anti-PD-1 Therapy in Metastatic Melanoma (STOP-GAP)

Titre officiel

A Randomized Phase III Trial of the Duration of Anti-PD-1 Therapy in Metastatic Melanoma (STOP-GAP)

Sommaire:

L’objectif de cette étude consiste à comparer les effets qu’a sur le mélanome la prise de l’inhibiteur des récepteurs du PD-1 approuvé et payé par le régime public par rapport à la prise du même type de médicament de façon continue. Les chercheurs tentent de savoir si les deux méthodes d’administration de ce type de traitement ont les mêmes effets positifs de prolonger la vie des patients atteints d’un mélanome.

Description de l'essai

Primary Outcome:

  • Overall survival
Secondary Outcome:
  • Progression-free survival using RECIST 1.1 / Immune-Related RECIST (irRECIST)
  • Response rate using RECIST 1.1 / Immune-Related RECIST (irRECIST)
  • Duration of response using RECIST 1.1 / Immune-Related RECIST (irRECIST)
  • Number and severity of adverse events using CTCAE v 4.0
  • Quality of Life measured by EORTC QLQ-C30
  • Economic evaluation consisting of both healthcare utilization and health utilities measured by the EQ-5D questionnaire
The standard or usual treatment for this disease is to receive treatment with a class of agents known as PD-1 inhibitors, or also with the names anti-PD-1 therapy, immunotherapy and checkpoint inhibitors. PD-1 inhibitors turn on the immune system, so that it can fight the cancer cells in the body. Clinical trials have shown that PD-1 inhibitors (such as pembrolizumab and nivolumab) can shrink tumours and extend the life of patients with melanoma. To-date, PD-1 inhibitors have been given to patients with melanoma continuously (non-stop), for as long as they remain beneficial, for up to a total duration of 2 years. The 2 year duration was chosen because doctors thought it was reasonable, and has been adopted as the standard or usual duration because it was shown to work in clinical trials. However, some recent observations suggest that PD-1 inhibitors may work just as well if they are given for a shorter time and/or in an intermittent schedule. Intermittent means to take breaks from receiving the drug when, and for as long as, the melanoma is better. The investigators doing this study are interested to find out whether patients with melanoma live as long when the PD-1 inhibitors are given continuously (non-stop) or in an intermittent schedule (taking breaks). If the two ways of giving the treatment were to be shown to be just as good, benefits of an intermittent schedule may include less clinic visits and side effects, better quality of life, and less cost over time for the Health Care System. However, this is not known at present.
