14.2 Recent Myocardial Infarction, Recent Stroke, or Established Peripheral Arterial Disease

CAPRIE
The CAPRIE trial was a 19,185-patient, 304-center, international, randomized, double-blind, parallel-group study comparing clopidogrel (75 mg daily) to aspirin (325 mg daily). To be eligible to enroll, patients had to have: 1) recent history of myocardial infarction (within 35 days); 2) recent histories of ischemic stroke (within 6 months) with at least a week of residual neurological signs; and/or 3) established peripheral arterial disease (PAD). Patients received randomized treatment for an average of 1.6 years (maximum of 3 years).

The trial’s primary outcome was the time to first occurrence of new ischemic stroke (fatal or not), new myocardial infarction (fatal or not), or other vascular death. Deaths not easily attributable to nonvascular causes were all classified as vascular.

Table 6: Outcome Events in the CAPRIE Primary Analysis

Patients Clopidogrel n=9,599 Aspirin n=9,586
Ischemic stroke (fatal or not) 438 (4.6%) 461 (4.8%)
MI (fatal or not) 275 (2.9%) 333 (3.5%)
Other vascular death 226 (2.4%) 226 (2.4%)
Total 939 (9.8%) 1,020 (10.6%)

As shown in Table 6, clopidogrel was associated with a lower incidence of outcome events, primarily MI. The overall relative risk reduction (9.8% vs 10.6%) was 8.7%, p=0.045. Similar results were obtained when all-cause mortality and all-cause strokes were counted instead of vascular mortality and ischemic strokes (risk reduction 6.9%). In patients who survived an on-study stroke or myocardial infarction, the incidence of subsequent events was lower in the clopidogrel group.

The curves showing the overall event rate are shown in Figure 7. The event curves separated early and continued to diverge over the 3-year follow-up period.

The statistical significance favoring clopidogrel over aspirin was marginal (p=0.045). However, because aspirin is itself effective in reducing cardiovascular events in patients with recent myocardial infarction or stroke, the effect of clopidogrel is substantial.
The CAPRIE trial enrolled a population that had recent MI, recent stroke, or PAD. The efficacy of clopidogrel relative to aspirin was heterogeneous across these subgroups (p=0.043) (see Figure 8). Nonetheless, this difference may be a chance occurrence because the CAPRIE trial was not designed to evaluate the relative benefit of clopidogrel over aspirin in the individual patient subgroups. The benefit was most apparent in patients who were enrolled because of peripheral arterial disease and less apparent in stroke patients. In patients who were enrolled in the trial on the sole basis of a recent myocardial infarction, clopidogrel was not numerically superior to aspirin.

14.3 No Demonstrated Benefit of Clopidogrel plus Aspirin in Patients with Multiple Risk Factors or Established Vascular Disease

CHARISMA
The CHARISMA trial was a 15,603 subject, randomized, double-blind, parallel group study comparing clopidogrel (75 mg daily) to placebo for prevention of ischemic events in patients with vascular disease or multiple risk factors for atherosclerosis. All subjects were treated with aspirin 75 mg to 162 mg daily. The mean duration of treatment was 23 months. The study failed to demonstrate a reduction in the occurrence of the primary endpoint, a composite of CV death, MI, or stroke. A total of 534 (6.9%) patients in the clopidogrel group versus 573 (7.4%) patients in the placebo group experienced a primary outcome event (p=0.22). Bleeding of all severities was more common in the subjects randomized to clopidogrel.

Advise patients not to take omeprazole or esomeprazole while taking clopidogrel tablets. Dexlansoprazole, lansoprazole, and pantoprazole had less pronounced effects on the antiplatelet activity of clopidogrel tablets than did omeprazole or esomeprazole [see Drug Interactions (7.1)].

Medication Guide


Clopidogrel Tablets, USP

(kloe-PID-oh-grel)


Read this Medication Guide before you start taking clopidogrel tablets and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking with your doctor about your medical condition or your treatment.
What is the most important information I should know about clopidogrel tablets?

1. Clopidogrel tablets may not work as well in people who:

  • have certain genetic factors that affect how the body breaks down clopidogrel. Your doctor may do genetic tests to make sure clopidogrel tablets are right for you.
  • take certain medicines, especially omeprazole (Prilosec ® *) or esomeprazole (Nexium ® *). Your doctor may change the medicine you take for stomach acid problems while you take clopidogrel tablets.

2. Clopidogrel tablets can cause bleeding which can be serious and can sometimes lead to death. Clopidogrel tablets are a blood thinner medicine that lowers the chance of blood clots forming in your body. While you take clopidogrel tablets:

  • you may bruise and bleed more easily
  • you are more likely to have nose bleeds
  • it will take longer for any bleeding to stop

Call your doctor right away if you have any of these signs or symptoms of bleeding:

  • unexpected bleeding or bleeding that lasts a long time
  • blood in your urine (pink, red or brown urine)
  • red or black stools (looks like tar)
  • bruises that happen without a known cause or get larger
  • cough up blood or blood clots
  • vomit blood or your vomit looks like coffee grounds

Do not stop taking clopidogrel tablets without talking to the doctor who prescribes it for you. People who stop taking clopidogrel tablets too soon have a higher risk of having a heart attack or dying. If you must stop clopidogrel tablets because of bleeding, your risk of a heart attack may be higher.
What are clopidogrel tablets?
Clopidogrel tablets are prescription medicines used to treat people who have any of the following:

  • chest pain due to heart problems
  • poor circulation in their legs (peripheral arterial disease)
  • a heart attack
  • a stroke

Clopidogrel is used alone or with aspirin to lower your chance of having another serious problem with your heart or blood vessels such as heart attack, stroke, or blood clot that can lead to death.
Platelets are blood cells that help your blood clot normally. Clopidogrel tablets help to prevent platelets from sticking together and forming a clot that can block an artery.
It is not known if clopidogrel tablets are safe and effective in children.
Who should not take clopidogrel tablets?
Do not take clopidogrel tablets if you:

  • currently have a condition that causes bleeding, such as a stomach ulcer.
  • are allergic to clopidogrel or other ingredients in clopidogrel tablets. See the end of this leaflet for a complete list of ingredients in clopidogrel tablets.

What should I tell my doctor before taking clopidogrel tablets?
Before you take clopidogrel tablets, tell your doctor if you:

  • have a history of bowel (gastrointestinal) or stomach ulcers
  • have a history of bleeding problems

  • are pregnant or plan to become pregnant. It is not known if clopidogrel tablets will harm your unborn baby
  • are breastfeeding or plan to breastfeed. It is not known if clopidogrel passes into your breast milk. A decision should be made with your healthcare provider to avoid or discontinue breastfeeding when continuing clopidogrel is needed.
  • have had an allergy or reaction to any medicine used to treat your disease.

Tell all of your doctors and your dentist that you are taking clopidogrel tablets. They should talk to the doctor who prescribed clopidogrel tablets for you before you have any surgery or invasive procedure.

Tell your doctor about all the medicines you take , including prescription, non-prescription medicines, vitamins and herbal supplements.
Clopidogrel tablets may affect the way other medicines work, and other medicines may affect how clopidogrel tablets work. See “What is the most important information I should know about clopidogrel tablets?
Clopidogrel tablets may increase blood levels of other medicines such as repaglinide (Prandin®*).
Taking clopidogrel tablets with certain other medicines may increase your risk of bleeding.
Especially tell your doctor if you take:

  • aspirin, especially if you have had a stroke. Always talk to your doctor about whether you should take aspirin along with clopidogrel tablets to treat your condition.
  • Non-steroidal anti-inflammatory drugs (NSAIDs). Ask your doctor or pharmacist for a list of NSAID medicines if you are not sure.
  • warfarin (Coumadin® *, Jantoven® *)
  • selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs). Ask your doctor or pharmacist for a list of SSRI or SNRI medicines if you are not sure.
