NCT01597375

Brief Summary

The investigators are doing this research study to find out if giving a drug called prasugrel, which is used to prevent blood clots, can reduce reactions to aspirin in people with aspirin exacerbated respiratory disease (AERD), and to learn why taking aspirin every day can work as a treatment for people with AERD. People with AERD have symptoms of asthma, severe runny nose, polyps in the nose, and develop allergic reactions if they take medications like aspirin. People with AERD can be desensitized to aspirin in order to be able to safely use it daily, but the investigators do not know if prasugrel may prevent reactions to aspirin and provide a safer way for people with AERD to tolerate aspirin. The investigators also want to understand what is different about the cells and urine from subjects who have AERD, in comparison to subjects who have asthma but do not have AERD and subjects who have allergic rhinitis but do not have asthma. Lastly, the investigators want to understand how aspirin acts differently in subjects who have AERD, in comparison to subjects who have asthma but do not have AERD.

Outcome Measures

Primary Outcomes (2)

  • Difference in PD2 (Provocative Dose of Aspirin That Elicits an Increase in Nasal Symptom Score of 2 During an Aspirin Challenge) on Prasugrel Versus Placebo

    The PD2 is the provocative dose of aspirin that elicits an increase in nasal symptom score of 2 during an aspirin challenge. The PD2 is calculated by: inverse〖log〗\_10 (((2-(PrevTNSS-BaselineTNSS))×(〖log〗\_10 ProvocDose-〖log〗\_10 PrevDose))/((MaxTNSS-BaselineTNSS)-(PrevTNSS-BaselineTNSS) )+(〖log〗\_10 PrevDose))

    Difference in PD2 (provocative dose of aspirin that elicits an increase in nasal symptom score of 2 during an aspirin challenge) between Visits 2 and 3 (weeks 8 and 14), calculated at visit 3

  • Change From Baseline Expression Levels of COX-2 Transcript and Protein in Peripheral Blood Leukocytes of Subjects With AERD After 8 Weeks of Treatment With Aspirin.

    This study will compare this outcome within each participant between baseline (established at Visit 1, prior to initiation of prasugrel therapy) and at the completion of 8 weeks of aspirin therapy.

    Evaluated at visits 1 and 4 (weeks 4 and 22)

Secondary Outcomes (6)

  • Difference in Participant's Provocative Dose of Aspirin When Pretreated With Prasugrel Versus Placebo

    Evaluated at visits 2 and 3 (weeks 8 and 14)

  • Change in Total Nasal Symptom Score(TNSS)From Baseline to Peak During Aspirin Challenge on Placebo Versus Prasugrel.

    Data obtained at visits 2 and 3 (weeks 8 and 14) and change calculated at visit 3

  • Change in Urinary LTE4 During Aspirin Challenge on Placebo Versus Prasugrel

    Change from visits 2 at visit 3 (weeks 8, 14), calculated and reported at visit 3

  • Change From Baseline in Fractional Exhaled Nitric Oxide (FeNO) Measurement After Aspirin Desensitization and High Dose Aspirin Treatment at 8 Weeks

    Evaluated at baseline and reported at 8 weeks

  • Change From Baseline in Asthma Control Questionnaire-7 (ACQ-7) Score After Aspirin Desensitization and High Dose Aspirin Treatment at 8 Weeks

    Evaluated at baseline and reported at 8 weeks

  • +1 more secondary outcomes

Other Outcomes (2)

  • Baseline Differences in Platelet Chemistry in Subjects With AERD Compared to Controls

    Evaluated at visit 1 (week 4)

  • Effect of Prasugrel on Platelet Chemistry in Subjects With AERD During Aspirin Challenge.

    Evaluated at visit 2 and 3 (week 8 and 14)

Study Arms (2)

Placebo then Prasugrel

EXPERIMENTAL

Subjects with AERD first received placebo oral tablet for 4 weeks prior to their aspirin challenge/desensitization. After aspirin challenge/desensitization subjects were discharged to home to washout the study drug from the first treatment phase. At the end of the 2-week washout period, subjects crossed over to the alternate treatment for 4 weeks of Prasugrel oral tablets \[ (5 mg (for patients \<60kg) or 10mg (\> 60kg) daily, following a 60mg loading dose)\] and returned for the second aspirin challenge. Because no period effect was observed, data obtained from all subjects while on placebo from either visit 2 or 3 were combined.

Interventions

Participants will take a 60 mg loading dose. After they will take 10 mg by mouth daily if they weigh \>60kg or 5 mg by mouth daily if they weigh \<60 kg. They will take the drug for 4 weeks prior to the aspirin challenge/desensitization.
