About this study
Official title: A Double-blind, Randomized, Placebo-controlled Trial to Evaluate the Efficacy of Intravenous Immunoglobulin Therapy in Autoimmune Autonomic Ganglionopathy.
The purpose of the study is to see if administering intravenous immune globulin (IVIG) (putting immune globulin directly into your blood) helps to improve the symptoms of orthostatic hypotension (sudden fall in blood pressure when a person stands up) and quality of life in men and women who have autoimmune autonomic ganglionopathy (AAG).
Read the detailed description
Autoimmune autonomic ganglionopathy (AAG) is a rare disease that results in severe dysautonomia (disorder of autonomic nervous system function). Many patients are unable to carry out activities of daily living due to autonomic symptoms that do not respond well to therapy (such as drops in blood pressure while standing). The recent discovery of antibodies that cause AAG has stimulated interest in immunomodulatory therapy (therapies that modify the functioning of the immune system). Studies in which a positive clinical response to these therapies have been reported in patients with AAG using immunomodulatory therapy as a treatment.
The investigators plan to carry out a blinded, randomized trial using IVIG. There have been no reported randomized clinical trials with any immunosuppressive agent in AAG. The proposed studies, if successful, will provide the first reliable clinical evidence, that therapy with IVIG is an effective treatment of AAG.
Treatment for the symptoms of autonomic failure is only effective in mild cases. Most patients require therapy that would change the course of the disease, but at present there is no established therapeutic regimen. The natural course of untreated AAG is not known.
To address these unresolved issues, this clinical trial has the following goals:
- To measure the effect of IVIG treatment on orthostatic hypotension, autonomic symptoms and quality of life scores in patient participants with AAG.
- To determine the durability of IVIG (how long the treatment is effective) on orthostatic hypotension, autonomic symptoms and quality of life scores in patient participants with AAG.
Participants enrolled in the study will receive two courses of intravenous immunoglobulin or placebo separated by 3 weeks. During the First Observation Period, participants will be evaluated after 6 weeks to determine the clinical response and natural history of the disorder.
All the participants will then move to a single blinded second observation period.
All patients enrolled in the study (IVIG group and placebo group) will receive two infusions of intravenous immunoglobulin, i.e., both cohorts will receive IVIG (although participants will not know this, and physicians will not be aware if this treatment is to IVIG naïve or IVIG continued participants).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Double blinded IVIgDrug
Also called Gammagard
Participants will receive study treatment with IVIg, at 2.0 gm/kg over 2-4 consecutive days. A maintenance study treatment IVIg, at 1.0 gm/kg, over 1-2 consecutive days will occur three weeks later. All participants will proceed to the single blind Second Observation Period.
Double blinded PlaceboOther
Participants will receive placebo (5% albumin) at 2.0 gm/kg over 2-4 consecutive days. A maintenance treatment with placebo (5% albumin) at 1.0 gm/kg, over 1-2 consecutive days will occur three weeks later. All participants will proceed to the single blind Second Observation Period.
Single Blinded IVIgOther
This is the single blind Second Observation Period. All participants will receive study treatment with IVIg, at 2.0 gm/kg over 2-4 consecutive days. A maintenance study treatment at 1.0 gm/kg, over 1-2 consecutive days will occur three weeks later.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Systolic Blood Pressure During 60° Tilt (ΔSBP)
The primary outcome, the change in systolic blood pressure during 60 degree tilt (ΔSBP), will be assessed in all study participants at baseline and at 6 weeks.
Measured: Baseline and 6 weeks
Secondary outcomes (5)
Change in Systolic Blood Pressure During 60° Tilt (ΔSBP)
To compare the change in systolic blood pressure during 60 degree head up tilt table test after 6 and 12 weeks of IVIG (the within-patient difference in ΔSBP at 12 and 6 weeks among treated patients).
Measured: 6 weeks and 12 weeks
Composite Autonomic Symptom Score [COMPASS] Questionnaire
To determine the change in autonomic symptoms (measured by the composite autonomic symptom score [COMPASS] questionnaire) measured at baseline and 6 weeks. Minimum and maximum score possible: 0-100. We have reported the Total score. Higher values represent worse outcome.
Measured: Baseline, 6 weeks
Composite Autonomic Severity Score (CASS) Questionnaire.
To determine the change in autonomic symptoms (measured by the composite autonomic severity score [CASS]) measured at baseline and 6 weeks in individuals receiving IVIg.
Is a 10-point composite autonomic scoring scale of autonomic function. This scale allots 4 points for adrenergic and 3 points each for sudomotor and cardiovagal failure. Subjects with a score of 3 or less on have a mild autonomic failure, 4-6 have moderate autonomic failure and those with scores of 7 to 10 have severe failure. The minimum score possible is 3 and maximum is 10.
Measured: Baseline, 6 weeks
EuroQol [EQ-5D] Questionnaire.
To determine the change in quality of life (measured by the EuroQol [EQ-5D]) measured at baseline and 6 weeks in individuals receiving IVIg. We have reported the subscale (EQ-VAS). The minimum score is 0 and maximum score is 100. (0) corresponds to " the worst health you can imagine", and the highest rate (100) corresponds to "the best health you can imagine".
Measured: Baseline, 6 weeks
Orthostatic Hypotension Symptom Assessment Questionnaire
To determine the change in orthostatic Hypotension symptom (measured by the orthostatic hypotension symptom assessment questionnaire) measured at baseline and 6 weeks in individuals receiving IVIG. This is a 60 point orthostatic hypotenstion symptom assessment questionnaire. The minimum score possible is 0 and maximum is 60.
Higher values represent worse outcome. We are reporting the total score.
Measured: Baseline, 6 weeks

The purpose of the study is to see if administering intravenous immune globulin (IVIG) (putting immune globulin directly into your blood) helps to improve the symptoms of orthostatic hypotension (sudden fall in blood pressure when a person stands up) and quality of life in men and women who have autoimmune autonomic ganglionopathy (AAG).

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Jul 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Systolic Blood Pressure During 60° Tilt (ΔSBP) (time frame: Baseline and 6 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01522235, which also lists 29 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
