Cabazitaxel can improve survival prospects
One study (TROPIC), which considered patient-relevant outcomes and provided relevant data, was included in the assessment of added benefit in the "best supportive care population". This study compared treatment with cabazitaxel versus mitoxantrone, in each case combined with prednisone and "best supportive care". In this context, mitoxantrone was regarded as a component of "best supportive care" for the assessment.
As IQWiG found, cabazitaxel can increase survival time, but the results vary with the age of patients. In patients aged 65 years or older, an indication of a major added benefit can be inferred with regard to overall survival. One can also assume an increase in survival time due to treatment with cabazitaxel in under 65-year-olds; however, the extent of this increase cannot be clearly determined, as the evidence base is less reliable here. In this age group, the data therefore only provide a "hint" of an added benefit, for which the extent cannot be quantified. The study also investigated the pain-relieving effect of the interventions as an aspect of the consequences of disease (morbidity). However, no relevant difference between the two treatment groups was shown. No data were available on health-related quality of life.
Also indication of greater harm due to severe side effects
In the "best supportive care population", the data also provide indications of greater harm in the form of side effects (adverse events). For example, severe adverse events, such as severe diarrhoea, anaemia or neutropenia, occurred more often in the cabazitaxel group. IQWiG classifies the extent of this greater harm as considerable for these outcomes. There is even an indication of major harm for the category "serious adverse events"; these are adverse events that, for example, lead to hospital admission, are life-thre
