keskiviikko 10. lokakuuta 2012 päivittänyt: AstraZeneca

A Phase IIa, Double-blind, Randomized, 2-way Cross-over Study to Evaluate the Effect of a Single Dose of AZD1386 95 mg Compared to Placebo in a Multimodal Experimental Pain Model on Esophageal Sensitivity in GERD Patients With a Partial Response to PPI Treatment

The purpose of the study is to compare sensitivity of visceral pain in the esophagus using different pain stimuli.

Mitä tutkimuksessa mitataan?

Ensisijaiset tulostoimenpiteet

Tulosmittaus
Toimenpiteen kuvaus
Aikaikkuna
Time to Visual Analogue Scale 7 (VAS7) During Thermal Stimulation at 1.5 Hours Post-Dose.
Aikaikkuna: 1.5 hours post dose

A probe (bag) was inserted 7cm above the lower esophageal sphincter (LES). Heat stimuli were applied by recirculation of heated water in the bag. Prior to recirculation the bag is filled with 7mL to ensure adequate mucosal contact. Water was heated up to a maximum of 63° C and the stimulation was continued until VAS 7 was reached.

The intensities of the non-painful sensations were scored with the following descriptors added to facilitate the scoring:

  1. = vague perception of mild sensation
  2. = definite perception of mild sensation
  3. = vague perception of moderate sensation

  4. = definite perception of moderate sensation

    For painful sensations the patients will use the scale from 5-10 anchored at:

  5. = pain detection
  6. = slight pain
  7. = moderate pain
  8. = medium pain intensity
  9. = intense pain
  10. = unbearable pain
1.5 hours post dose
