Antithrombotic treatment for the secondary prevention of stroke

Question

Can apixaban 5 mg twice daily be used for the secondary prevention of stroke in patients with atrial fibrillation?

Recommendations

  1. After analysing the evidence available on apixaban compared to warfarin (given the lack of other comparators in the literature meeting the proposed criteria for inclusion and prioritisation), the following recommendation was made:

    In adult patients with indications for secondary prevention of stroke and nonvalvular atrial fibrillation, we suggest using apixaban rather than warfarin.

     

Rationale

Below, we outline the rationale for one of the recommendations, highlighting the judgements of the GDG concerning the key criteria that justify the final recommendation.

The GDG considered reduction in stroke recurrence (a desirable effect) and severe bleeding (an undesirable effect) to be the most important outcomes for assessing potential benefits. Regarding stroke recurrence, it considered the reduction observed in patients treated with apixaban compared to those treated with warfarin to be significant (16 fewer cases of stroke per 1000; a relative reduction of 29%). Regarding severe bleeding, it was considered that the risk of bleeding was lower in patients treated with apixaban than those treated with warfarin (16 cases of bleeding per 1000, a relative reduction of 27%). These considerations justified a recommendation in favour of the use of apixaban.

This recommendation was additionally supported by evidence in the literature of the importance patients place on reducing stroke recurrence (rating it even higher than avoiding death). Further, health professionals considered that apixaban was easier to use given that it does not require regular monitoring and shows little interaction with foods or other drugs.

Similarly, the GDG indicated that improvements in patient quality of life observed in clinical experience with apixaban supported this weak recommendation in favour.

Question

Can dabigatran 110 mg twice daily be used for the secondary prevention of stroke in patients with atrial fibrillation?

Recommendations

After analysing the evidence available on 110 mg dabigatran compared to warfarin (given the lack of other comparators in the literature meeting the proposed criteria for inclusion and prioritisation), the following recommendation was made:

In adult patients with an indication for the secondary prevention of stroke and non-valvular atrial fibrillation, we suggest using dabigatran 110 mg twice daily rather than warfarin.

Rationale

Below, we outline the rationale for one of the recommendations, highlighting the judgements of the GDG concerning the key criteria that justify the final recommendation.

The GDG indicated that the all-cause and vascular mortality outcomes may differ significantly in favour of the intervention. It considered that the benefit of the intervention (25 fewer all-cause deaths per 1000 treated with 110 mg dabigatran, a relative reduction of 28%) was relevant and conclusive in favour of the intervention, as the confidence interval (CI) did not include the null value.

The benefits in terms of safety were favourable for dabigatran 110 mg, with a lower risk of bleeding with this treatment compared to warfarin (27 fewer cases of bleeding per 1000, a relative reduction of 33%), and the CI did not include the null value; however, regarding myocardial infarction, dabigatran 110 mg had an undesirable effect, with three more events in the intervention group than the comparator (warfarin), although the results were not conclusive given that the CI did include the null value.

The GDG considered that the risk-benefit balance was favourable for dabigatran 110 g compared to warfarin.

The magnitude of the desirable and undesirable effects in relation to all-cause mortality, vascular mortality and severe bleeding may be considered moderate (favourable for the intervention); however, evidence on the outcomes of acute myocardial infarction and stroke recurrence was inconclusive.

The GDG indicated that the weak recommendation in favour was also supported by improvements in patient clinical condition and quality of life observed in clinical experience with dabigatran 110 mg, as well as the greater ease of use, with no requirement for monitoring and only a weak interaction with foods and other drugs.

Question

Can dabigatran 150 mg twice daily be used for the secondary prevention of stroke in patients with atrial fibrillation?

Recommendations

After analysing the evidence available on dabigatran 150 mg compared to warfarin (given the lack of other comparators in the literature meeting the proposed criteria for inclusion and prioritisation) the following recommendation was made.

In adult patients with an indication for secondary prevention of stroke and non-vascular atrial fibrillation, we suggest using dabigatran 150 mg twice daily rather than warfarin.

Rationale

Below, we outline the rationale for one of the recommendations, highlighting the judgements of the GDG concerning the key criteria that justify the final recommendation.

The GDG stated that the were no significant differences in favour of or against the intervention for any of the outcomes. Nonetheless, the GDG indicated that a weak recommendation in favour was supported by improvements in patients’ clinical condition and quality of life observed in clinical experience with dabigatran 150 mg, as well as the greater ease of use, with no requirement for monitoring and only a weak interaction with foods and other drugs.

The weak recommendation in favour of the intervention is the result of weighing the risk-benefit balance in favour of or against dabigatran 150 mg, very low confidence in the evidence and uncertainty concerning whether the reported effect of the intervention might differ from the true effect. The magnitude of the desirable and undesirable effects may be considered small for all the outcomes except for the reduction in acute myocardial infarction, which could be considered moderate in favour of the comparator (warfarin).

Question

Can edoxaban 60 mg once daily be used for the secondary prevention of stroke in patients with atrial fibrillation?

Recommendations

After analysing the evidence available on edoxaban compared to warfarin (given the lack of other comparators in the literature meeting the proposed criteria for inclusion and prioritisation), the following recommendation was made:

In adult patients with an indication for the secondary prevention of stroke and non-valvular atrial fibrillation, we suggest using edoxaban rather than warfarin.

Rationale

Below, we outline the rationale for one of the recommendations, highlighting the judgements of the GDG concerning the key criteria that justify the final recommendation.

The GDG considered that the cardiovascular mortality outcome (desirable effect: a reduction) provided the most important benefits. It considered that the benefit of the intervention (20 fewer deaths per 1000, a relative reduction of 21%) was significant; the benefit in terms of safety was favourable for edoxaban, with a lower risk of bleeding with this treatment than with warfarin (13 fewer cases of bleeding per 1000, a relative reduction of 16%). Nonetheless, the CI included the null value, and hence, the GDG had little confidence in the evidence, as the effect of the intervention obtained in the study might differ from the true effect.

In this comparison, results in terms of stroke recurrence supported the intervention (9 fewer cases of stroke per 1000), although the CI did include the null value. The recommendation was also influenced by some studies having described patients preferring a reduction in stroke recurrence over improvements in other outcomes (even death).

The magnitude of the desirable and undesirable effects may be considered small.

The GDG had very low confidence in the estimate of the effect, especially because of the risk of bias and imprecision in the results, and hence, the risk-benefit balance was not clear and showed only weak support for benefits.

Nonetheless, the GDG indicated that a weak recommendation in favour was supported by improvements in patients’ clinical condition and quality of life observed in clinical experience with edoxaban.

The conditional recommendation in favour of the intervention was reached after assessing the risk-benefit balance of using edoxaban rather than warfarin for the secondary prevention of stroke. In this assessment, it was considered that the balance would be positive (beneficial), although with a very low level of confidence in the available evidence, the expected effect possibly differing from the true effect (in the real world).

For the aforementioned reasons, the recommendation is weakly in favour of the intervention (edoxaban) over the comparator (warfarin).

Question

Can rivaroxaban 15-20 mg once daily be used in patients with atrial fibrillation for the secondary prevention of stroke?

Recommendations

After analysing the evidence available on rivaroxaban compared to warfarin (given the lack of other comparators available such as acenocoumarol), the following recommendation was made:

In adult patients with an indication for the secondary prevention of stroke and non-valvular atrial fibrillation, we suggest using rivaroxaban rather than warfarin.

Key clinical considerations: the usual warnings and precautions for use listed in the summary of product characteristics were identified and special emphasis was placed on the need to check for adequate kidney function. There was insufficient evidence to make recommendations by subgroup, although there could be differences by sex and age.

Rationale

Below, we outline the rationale for one of the recommendations, highlighting the judgements of the GDG concerning the key criteria that justify the final recommendation.

The majority opinion in the GDG was that, in general, treatment with rivaroxaban has similar effects to that of treatment with warfarin for the secondary prevention of stroke in terms of the variables included in the analysis with the GRADE Evidence to Decision (EtD) framework and evidence profiles or tables. It was considered relevant to analyse certain variables associated with severe bleeding in patients with a history of stroke which had not previously been included. These variables were fatal bleeding (which could be considered “major bleeding”) and extracranial bleeding. In the case of the former, a relative risk (RR) of 0.98 (95% CI: 0.80–1.20) was observed with 44 cases per 1000 treated with rivaroxaban and 45 cases per 1000 treated with warfarin. For this reason, the GDG concluded that it could suggest treatment with rivaroxaban rather than warfarin in patients with a risk of bleeding (the majority of patients) .

Regarding the other variables, compared to warfarin, rivaroxaban for the secondary prevention of stroke had similar absolute effects (per 1000 patients treated, rivaroxaban being associated with 1 fewer case of stroke [95% CI: 9 fewer to 10 more strokes], 2 fewer cases of all-cause mortality [95% CI: 13 fewer to 10 more deaths], the same stroke-related mortality [95% CI: 3 fewer to 2 more] and 1 fewer case of vascular mortality [95% CI: 10 fewer to 10 more deaths]) and similar adverse effects (rivaroxaban being associated with 1 fewer case of severe bleeding [95% CI: 9 fewer to 10 more cases], 2 more cases of myocardial infarction [95% CI: 3 fewer to 9 more cases, and the same risk of systemic embolism). It should be highlighted that the assessment carried out by the methodology working group for this guideline considered that the studies included had limitations as a result of the risk of bias or imprecision while the GDG indicated that improvements in patients’ clinical condition and quality of life in clinical experience with this treatment supported the weak recommendation in favour.
