2 results from studies that gave the peptide. 2 results from people.

  1. 01HumanRandomized controlled trialEfficacy outcome

    In Parkinson's disease, prior exenatide exposure gave a 5.6-point motor score advantage versus controls after treatment cessation.

    In plain wordsPatients with Parkinson's disease previously receiving exenatide had better motor scores than controls after treatment stopped.

    Summary
    Compared to the control group of patients, patients previously exposed to exenatide had an advantage of 5.6 points (95% CI, 2.2-9.0; p = 0.002) using blinded video rating of the MDS-UPDRS part 3 motor subscale.
    3 context sentences
    Summary · context
    All participants from an open label, randomised controlled trial of exenatide as a treatment for Parkinson's disease, were invited for a further follow up assessment at the UCL Institute of Neurology.
    Summary · context
    This visit included all 20 individuals who had previously completed twelve months exposure to exenatide 10ug bd and the 24 individuals who had acted as randomised controls.
    Summary · context
    This assessment was thus 24 months after their original baseline visit, i.e. 12 months after cessation of exenatide.
  2. 02HumanRandomized controlled trialEfficacy outcome

    In Parkinson's disease, prior exenatide exposure gave a 5.3-point cognitive score advantage versus controls after treatment cessation.

    Summary
    There was also a difference of 5.3 points; (95% CI, 9.3-1.4; p = 0.006) between the 2 groups on the Mattis Dementia Rating scale.
