Dual Antiplatelet Therapy Duration after Cardiac Stent Placement or Acute Coronary Syndrome: How Long is Long Enough?

Taryn B. Bainum, Pharm.D., BCPS, David G. Brabham, DO

Cardiovascular disease results in over 2,150 deaths each day in the United States, averaging out to approximately 1 death every 40 seconds according to 2011 data from the American Heart Association. It has been estimated that roughly 635,000 Americans have a coronary attack each year and 300,000 of these patients will have recurrent attacks. These acute coronary syndromes (ACS) and coronary artery disease (CAD) events often result in a cardiovascular procedure or operation. The number of cardiovascular procedures increased by 28% from 2000 to 2010, highlighting the need for optimal treatment for these common disease states.1

Dual antiplatelet therapy (DAPT) is used to reduce thrombotic complications associated with ACS and cardiac stent implantation as well as to reduce atherothrombotic events. Dual antiplatelet therapy generally consists of an aspirin in addition to an oral P2Y12 receptor inhibitor such as clopidogrel, ticagrelor, or prasugrel. While the combination of these medications has been shown to reduce cardiovascular events in patients following an acute coronary syndrome or stent placement2-4, the duration of this therapy has been widely debated.

This year the American College of Cardiology and American Heart Association published an updated guideline regarding the duration of dual antiplatelet therapy in patients with CAD. The recommendations published in these guidelines are presented in Table 1.5 The guideline addresses the duration of DAPT in several clinical situations in addition to recommending to utilize aspirin long-term at a dose of 75-100 mg daily rather than a higher dose of aspirin due to comparable ischemic protection and lower bleeding risks.6

Eleven randomized controlled trials were assessed to determine the optimal duration of DAPT following stent implantation, most of which focused on drug-eluting stents (DES). The DAPT trial was the largest of these, evaluating 9,961 patients. This trial was designed to assess superiority of 30 months of DAPT over 12 months after the placement of newer generation DES. The longer duration of DAPT was shown to reduce the rate of stent thrombosis, major adverse cardiac cerebrovascular events (MACCE), and myocardial infarction (MI) significantly, but was associated with significantly increased rates of moderate or severe bleeding and borderline increased mortality.7,6 Upon further study, the number of cancer-related deaths was found to be significantly different between groups and subsequently it was discovered that the more cancer patients had been enrolled into the longer DAPT duration arm.7 The guideline states a number of writing group members did not believe the data suggests increased mortality is associated with DAPT. Because the data on this subject is conflicting, clinicians are urged to evaluate patients based on factors such as the patient’s bleeding risk, tolerance of DAPT after the minimum suggested time period, and concomitant medications such as anticoagulants.5

A new risk score from the Dual Antiplatelet Therapy Study, the “DAPT score,” may be useful in determining the risk/benefit ratio of prolonged DAPT therapy in patients following coronary stent implantation. Data from this study suggests that a DAPT score of ≥ 2 after 1 year of treatment with aspirin and a P2Y12 inhibitor indicates a favorable benefit/risk ratio whereas a score of < 2 may indicate the potential benefits of prolonged DAPT therapy do not outweigh the risks.5,8 This score illustrates that younger patients are at a lower risk of bleeding and patients with prior history of ACS, or other cardiac risk factors results in a high score, are more likely to experience prevention of an ischemic event than bleeding. A study evaluating this score showed the number needed to treat in order to prevent an ischemic event for patients with a DAPT score ≥ 2 is 34 while the number needed to harm with a bleeding event was 272. Conversely for patients with a score less than 2, the number needed to prevent an ischemic event was 153 and the number needed to harm was 64. The DAPT score is shown in Table 2.5,8

Recently the PEGASUS-TIMI 54 trial was published examining the benefit of extended DAPT with ticagrelor in patients who had an MI 1-3 years prior to enrollment. The median duration of follow-up was 33 months. Patients were randomized to receive ticagrelor 60 mg twice daily, ticagrelor 90 mg twice daily, or placebo in addition to aspirin therapy. The primary endpoint was a composite of cardiovascular death, myocardial infarction, or stroke. The 60 mg dose of ticagrelor significantly reduced the primary endpoint, in addition to several secondary endpoints, however TIMI minor and major bleeding were increased as well. There was no significant difference in rates of fatal bleeding or nonfatal intracranial hemorrhage. Dyspnea, which has been associated with ticagrelor in other studies, was increased when compared to placebo.10 Overall the study suggest there may be benefit with regard to reduced ischemic events, however this comes with increased risk of bleeding.

The ACC/AHA guidelines have incorporated data from recent trials into their recommendations for duration of DAPT, but they also encourage clinicians to use their judgment to determine which patients might benefit from prolonged therapy and which should have DAPT discontinued after the minimum suggested timeframe. Until more trials evaluate this issue the optimal duration of DAPT is still uncertain. The patient’s individual risk for ischemic events and bleeding events remains the most important factor when making the decision to continue DAPT past the minimum suggested duration.

ACCP Adult Medicine PRN, Fall Newsletter Volume 11, Issue 2

Direct oral anticoagulant agents, also known as DOACs, have revolutionized the world of anticoagulation. The DOACs have been shown to be favorable over warfarin due to the need for less monitoring, fewer food and drug interactions, fixed dosing and less inter-patient variability.1 Agents currently on the market include rivaroxaban (Xarelto®), apixaban (Eliquis®), dabigatran (Pradaxa®) and edoxaban (Savaysa®). Rivaroxaban, apixaban and dabigatran are indicated for treatment of venous thromboembolisms (VTE), VTE prophylaxis following orthopedic surgery, and non-valvular atrial fibrillation.2,3,4 Edoxaban is currently only approved for treatment of VTE and non-valvular atrial fibrillation.5

The 2016 CHEST guidelines for Antithrombotic Therapy for VTE Disease have updated recommendations regarding the use of DOACs for treatment of VTE for the first time since 2012.6,7 The panel now recommends rivaroxaban, apixaban, dabigatran, or edoxaban over vitamin K antagonists (VKAs) and low-molecular weight heparin (LMWH) for initial and long-term treatment of deep vein thrombosis (DVT) or pulmonary embolism (PE) in patients without cancer (grade 2B recommendation). The panel’s overall assessment is that DOACs have a similar VTE risk reduction to warfarin with a reduced risk for bleeding, with apixaban possibly having the lowest bleeding risk.7

Populations included in DOAC clinical trials do not reflect patients at extremes of weight or those with renal dysfunction. With the new CHEST guideline recommendations, the question of whether DOACs can be used in a broader population will inevitably arise.

The literature is void of specific investigations of DOACs in an obese population (obesity defined as a BMI ≥ 30 kg/m2) via a large, randomized trial. Phase III efficacy and safety trials did not completely exclude this population, although studies included varying numbers of obese patients and weight categories (Table 1).9-20 The mean weight of patients receiving DOACs was between 82 kg and 86.1 kg, and only some of the trials stratified patients based on weight category. The RECOVER II (dabigatran vs. warfarin for VTE treatment) trial did include a large number of patients with a BMI ≥ 35 (23.6%) and furthermore those ≥ 100 kg (34.2%). In this analysis, the dabigatran weight subgroup of > 100 kg was more likely to experience a primary outcome (VTE) than those weighing 50-100 kg.11 In other phase III efficacy trials, DOACs were similar to warfarin in the prevention of VTE and stroke in higher weight categories.9 These studies were not consistent in the weight categories analyzed for efficacy, not adequately powered to detect differences in thrombosis or bleeding in these subgroups and they did not include individuals at the very extreme of increased weight, such as those ≥ 200 kg.

Limited pharmacokinetic (PK) and pharmacodynamic (PD) data is available to aid in guidance of the use of DOACs in obesity. Newly approved edoxaban does not currently have weight-specific pharmacokinetic studies, however pooled data suggests that non-renal clearance was higher with increasing body weight.9 Rivaroxaban has been shown to have similar peak concentrations, area under the curve (AUC) and half-lives in patients > 120 kg versus those 70 to 80 kg, with results bearing uncertain clinical significance.9 Apixaban has shown significantly lower peak concentrations in those > 120 kg versus 65 to 85 kg in conjunction with a 23% lower AUC.9 Again, the effect size of these variances was low enough that the authors did not comment on dose adjustments for patients > 120 kg. Finally, dabigatran has been shown to display an inverse relationship between trough concentration and weight, with trough values 21% lower for those > 100 kg versus 50 to 100 kg.9 In summary, these PK and PD data still beg the question of whether or not patients of extreme body weight are being under-dosed, and presently no therapeutic drug ranges have been established for these agents and it is unknown if these differences lead to a change in clinical outcomes.

The Scientific and Standardization Committee of the International Society of Thrombosis and Haemostasis (ISTH) has recommended that DOACs not be used in patients with a BMI > 40 kg/m2 or a weight > 120 kg.9 Furthermore, they recommend monitoring drug-specific peak and trough levels if used in patients meeting this weight criteria, although this practice is likely not feasible or routine at most institutions.9 Unfortunately, product labeling for the DOACs do not include specific weight cut-offs or recommendations for when to consider an alternative agent.

The utilization of these agents in patients with renal dysfunction is also controversial. Table 1 displays either the mean creatinine clearance (CrCl) or the number of patients with a reduced CrCl enrolled in major efficacy trials. The majority of trials excluded patients with a CrCl < 30 ml/min, with a range of 0.2-1.5% of the total populations falling into this category. Per the package insert, rivaroxaban should be avoided in patients with a creatinine clearance (CrCl) < 30 ml/min.4 No dosage recommendations are provided for dabigatran at this level of renal dysfunction, although patients were excluded from clinical trials at a CrCl < 30 ml/min.3

NOACs, continued.

Apixaban has dosage adjustments for patients with non-valvular atrial fibrillation with two of the following: serum creatinine ≥ 1.5 mg/dL, age ≥ 80 years or body weight ≤ 60 kg2. Clinical studies did not enroll patients on hemodialysis, however one PK/PD study displayed similar apixaban concentrations to those observed in the ARISTOTLE trial at usual doses. Long-term safety and efficacy data for apixaban is not available in the hemodialysis population.2 Edoxaban dosing should be reduced from 60 mg daily to 30 mg daily in CrCl 15 to 50 ml/min, and use in <15 ml/min is not recommended. Interestingly, the use of edoxaban at CrCl > 95 ml/min is not recommended in patients with non-valvular atrial fibrillation, as this subgroup had an increased rate of thromboembolism in clinical trials.5 These variances create challenges for prescribers when trying to select an appropriate agent.

Data regarding safety of the use of these agents in renal dysfunction is limited, however meta-analyses have been conducted to investigate thrombotic and bleeding outcomes in this subgroup. One such study compared the use of DOACs versus warfarin for atrial fibrillation in renal dysfunction.21 In mild and moderate renal dysfunction (CrCl 50-80 ml/min and 25-49 ml/min, respectively), the DOACs were comparable to warfarin for safety in terms of risk of major bleeding. Indirect comparisons of the DOACs showed that apixaban had less major bleeding than dabigatran, rivaroxaban, and edoxaban 60 mg daily in moderate renal impairment, however edoxaban 30 mg daily was favorable in comparison to all other agents.21 The risk in interpretation and extrapolation of these results continues to be the absence of data in CrCl ≤ 30 ml/min. This meta-analysis also assumes homogeneity in the populations as well as safety and efficacy parameters, which is an overall limitation.

Similar to the PK/PD data for the use of DOACs in obesity, variations in renal dysfunction have uncertain correlations to clinical outcomes. In moderate renal impairment (CrCL 30-50 ml/min), dabigatran has been shown to have an increased AUC and half life (from 13 hours to 27 hours) compared to patients with normal renal function.22 An increase in aPTT has also been observed, albeit with no clinically significant bleeding. Rivaroxaban has shown an increased AUC and mildly prolonged half life in severe renal impairment (average CrCl 15 ml/min) with no associated bleeding events.22 Subgroup analyses of apixaban have demonstrated increased ischemic stroke coupled with increased major bleeding in CrCl < 50 ml/min.22 Finally, edoxaban displayed a 2.1% increase in bleeding at a CrCl < 30 ml/min.22 Overall, data is conflicting in regards to safety and efficacy of the use of DOACs in this special population. No direct investigation of DOACs in renal dysfunction has been conducted, therefore caution should be utilized when considering initiation of DOACs in clinical practice.

It is the responsibility of pharmacists to provide logical, evidence-based recommendations for whom to initiate therapy with one of the direct oral anticoagulant agents. Major societies such as the ISTH recommend avoiding the use of DOACs in patients at the upper extreme of weight.9 This is due to the lack of clinical data as well as PK/PD data with mixed results. More studies are needed to determine the safety and efficacy associated with the use of DOACs in obese patients and those with renal dysfunction.
