Drug Information available for: Droxidopa

Arm Intervention/treatment
Experimental: droxidopa

Droxidopa will be supplied in 100 and 200 mg pill sizes. The subject should administer the three doses 4 hours apart with the last dose prior to 4:00 pm (example: 8:00 am, 12:00 pm, and 4:00 pm). The proposed dosing is 100mg TID at baseline, then titrate slowly up to 600 mg TID. During titration, droxidopa or placebo, initiated at 100 mg TID was titrated upward in 100-mg TID increments every 48 hours until the subject:

  1. Reaches the maximum permitted dosage of 600 mg TID;
  2. Has a systolic blood pressure≥160mmHg or diastolic blood pressure ≥100mmHg after 10 minutes supine on 3 consecutive measurements; or
  3. Experiences intolerable adverse events (AEs).

Primary Outcome Measures :
  1. Evaluate the efficacy of droxidopa when measuring walking speed using the 10 meter walk test . [ Time Frame: 24 months ]

    10 meter walk test

    • Subject walks without assistance 10 meters (32.8 feet).
    • Assistive devices can be used but should be kept consistent and documented from test to test.
    • If physical assistance is required to walk, this should not be performed
    • Collect three trials and calculate the average of the three trials
    • Individuals are permitted to use the assistive device they typically use in the community, but without the assistance of another person.

  2. Evaluate the efficacy of droxidopa when measuring walking speed using Dual Task Timed Up and Go test [ Time Frame: 24 months ]
    • Subjects are given verbal instructions to stand up from a chair, walk 3 meters as quickly and safely as possible, cross a line marked on the floor, turn around, walk back, and sit down.
    • In the TUG (Cognitive), individuals were asked to complete the test while counting backward by threes from a randomly selected number between 20 and 100.

Secondary Outcome Measures :
  1. Evaluate the efficacy of droxidopa when measuring degree of thoracic curvature using the Flexicurve rule [ Time Frame: 24 months ]

    Flexi-curve measurement

    • Instruct subject to "stand in your usual best posture"
    • Identify C7 spinous process.
    • Identify the L-S interspace.
    • Mark each landmark (C7 process and L-S space) with a single horizontal grease pencil line.
    • Make sure the patient is standing in their usual best posture so that the marks are in the correct place during measurement using flexi-curve ruler.

  2. Evaluate the efficacy of droxidopa when measuring fall risk using the Forward Functional Reach test. [ Time Frame: 24 months ]

    Forward Functional Reach test

    • Using a yardstick mounted on the wall at shoulder height, ask the subject to position body close to, but not touching the wall with arm outstretched and hand fisted. Take note of the starting position by determining what number the MCP joints line up with on the rule.
    • Have the subject reach as far forward as possible in a plane parallel with the measuring device.
    • Instruct subject to "Reach as far forward as you can go without taking a step." Subjects are free to use various reaching strategies.
    • Take note of the end position of the MCP joints against the ruler, and record the difference between the starting and end position numbers.
    • If the feet move, that trial must be discarded and repeated.

  2. Clinical diagnosis of Parkinson's disease.
  3. Stable dose of current Parkinson's disease medication(s) for the past 2 weeks.
  4. Stable deep brain stimulator settings for the past 2 weeks.
  5. Provide written informed consent to participate in the study.

Exclusion Criteria:

  1. Concomitant use of vasoconstricting agents for the purpose of increasing blood pressure.

    Patients taking vasoconstricting agents such as ephedrine, dihydroergotamine, or midodrine must stop taking these drugs at least 2 days prior to baseline and throughout the duration of the study.

  2. Concomitant use of the following medications:
  3. Anti-hypertensive medication for the treatment of essential hypertension
  4. Vasoconstricting agents such as ephedrine, dihydroergotamine, or midodrine. Concomitant treatment for symptomatic NOH (with the exception of vasoconstricting agents) will be permitted during the study. This includes fludrocortisone, which is permitted during the study. Medications for the treatment of PD will be permitted during the study.
  5. Sumatriptan-like drugs, (for example, naratriptan, zolmitriptan, rizatriptan)
  6. Cyclopropane or halothane, or other halogen-containing inhalational anesthetics
  7. Catecholamine-containing preparations (e.g. isoprenaline)
  8. Non-selective monoamine oxidase inhibitors (MAOIs)
  9. Ergotamine derivatives (except if anti-Parkinsonian medication)
  10. Any investigational medication.
  11. Uncontrolled depression.
  12. Prior history of neuroleptic malignant syndrome.
  13. History of suicide attempt within the previous 2 years.
  14. Known or suspected alcohol or substance abuse within the past 12 months (DSM-IV definition of alcohol or substance abuse).
  15. Women who are pregnant or breastfeeding.
  16. Women of child bearing potential (WOCP) who are not using at least one method of contraception with their partner.
  17. Male patients who are sexually active with a woman of child bearing potential (WOCP) and not using at least one method of contraception.
  18. Untreated closed angle glaucoma, or treated closed angle glaucoma that, in the opinion of an ophthalmologist, might result in an increased risk to the patient.
  19. Sustained severe hypertension (BP ≥ 180 mmHg systolic or ≥ 110 mmHg diastolic in the seated or supine position which is observed in 3 consecutive measurements over an hour).
  20. Any significant uncontrolled cardiac arrhythmia.
  21. History of myocardial infarction, within the past 2 years.
  22. Current unstable angina.
