In continuation of my update on Nintedanib
According to the findings, there is an indication of a minor added benefit of nintedanib in combination with docetaxel in patients without brain metastases. However, in patients with brain metastases, the new drug has more disadvantages than chemotherapy with docetaxel alone. This results in a hint of a lesser benefit of nintedanib with the extent "considerable."
Findings from the only study are biased: at most indications can be derived
In its dossier the drug manufacturer compares treatment comprising nintedanib plus docetaxel with treatment comprising placebo plus docetaxel. As the treatment period in the nintedanib arm was longer than in the placebo arm (median: 4.3 versus 3 months), the observation periods for the study arms differed. Except for overall survival, the results are therefore uncertain for all outcomes.
In principle, at most an indication of an added benefit can be derived from the results of the only study included in the manufacturer dossier. As the analysis of the data shows, the advantages or disadvantages of nintedanib in combination with docetaxel primarily depend on whether patients already had brain metastases at the start of the study or not.
Patients without brain metastases live longer
Patients without brain metastases who received nintedanib in combination with docetaxel lived longer than study participants who were only treated with docetaxel (median: 13.5 versus 10.3 months). This results in an indication of a minor added benefit of nintedanib.
Although diarrhoea was more frequent in patients receiving nintedanib, this disadvantage does not challenge the survival advantage. Therefore, overall an indication remains of a minor added benefit for patients without brain metastases.
