Study summary

Ataxia telangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability and cancer susceptibility. The immunodeficiency is expressed by recurring infections. It's characterised by decreased lymphocytes data as well as lack of immunglobulin A, immunglobulin G subclasses and specific antibodies against pneumococcus. Aim of the present clinical trial is to investigate frequency-, intensity- and duration of the infections as well as changes oft immune status, dimension of liver disease and tumor risk in patients with A-T, with and without immunoglobulin G substitution therapy. Transient elastography (FibroScan) will be performed in order to measure liver stiffness as an indication of fatty liver and liver fibrosis. A bioelectrical impedance analysis (BIA) is conducted to investigate the exact body composition. Ataxia Score is determined to define neurological problems. Every subject receives a diary to compile symptoms of infection.

Read the detailed description

Ataxia teleangiectasia (A-T) is a rare devastating human recessive disorder characterized by progressive cerebellar ataxia, immunodeficiency, chromosomal instability and cancer susceptibility. The immunodeficiency is expressed by recurring infections. It's characterised by decreased lymphocytes data as well as lack of immunglobulin A, immunglobulin G subclasses and specific antibodies against pneumococcus as shown in many trials. Additionally the patients suffer from a fatty liver with increased transaminases and have the risk for a cirrhosis of the liver and a hepatocellular carcinoma. It's known that the dimension of the liver disease affects susceptibility to infection. Nevertheless there are only a few studies treating this problem.

Despite the proof of the immunodeficiency polyvalent immunoglobulins (IgG) are not given regularly. Own observations show that in spite of the treatment with immunoglobulins the progression of a chronic destructive lung disease with development of bronchiectasis hardly can prohibited.

Up to now it isn't cleared if a substitution therapy with immunoglobulins reduces the susceptibility to infection. Therefore the aim oft the present clinical trial ist to explore frequency-, intensity, and duration oft the infections as well as changes oft the immune status, measure of liver disease and tumor risk in patients with A-T, with and without immunoglobulin therapy. The study includes five visits, which are performed in all A-T patients. Visit 1, 3, 5 are realized in the context of annual follow ups:

  • To evaluate weight and length of all subjects
  • To analyze the exact structure of single body compartments such as the lean mass, the water compartment or the fat compartment using bioelectrical impedance analysis
  • To define the neurological status by ataxia score
  • To get a detailed immune status, vaccination status and liver values as well as special tumor markers in blood
  • To check the lung function using spirometry
  • To measure liver stiffness using transient elastography (FibroScan)
  • To compile any symptoms of infection by diary
  • To investigate the ataxia status and physical condition by means of the Five-Times-Sit-to-Stand Test

Visit 2 and 4 are additionally conducted as study visits:

  • To get a detailed immune status in blood
  • To check the lung function using spirometry

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

    A-T patients

    A-T patients aged 2 to 45 years with and without immunoglobulin G Substitution * bioelectrical impedance Analysis * blood draw * transient elastography (FibroScan) * ataxia score * Five-Times-Sit-to-Stand Test

    Diagnostic Test: bioelectrical impedance analysis · Diagnostic Test: blood draw · Diagnostic Test: transient elastography (FibroScan) · Diagnostic Test: ataxia score · Diagnostic Test: Five-Times-Sit-to-Stand Test

Interventions

  • Diagnostic testbioelectrical impedance analysis

    Electrophysical measurement that allows to determine the exact composition of single body compartments by producing a magnetic field and detecting the potential difference through the body

  • Diagnostic testblood draw

    Blood samples are taken from sober patients

  • Diagnostic testtransient elastography (FibroScan)

    FibroScan is a noninvasive tool to measure liver stiffness as an indication of fatty liver and liver fibrosis using ultrasound

  • Diagnostic testataxia score

    Klockgether ataxia score ranges from 0 to 35 points in which 0 means no symptoms and 35 stands for final stage of disease. It includes seven ataxia associated symptoms: dysarthria, intention tremor, ataxia of gait, stance, dysdiadochokinesia, upper limb and lower limb

  • Diagnostic testFive-Times-Sit-to-Stand Test

    The test measures the complete time which is necessary for an individual to stand up and sit down on a chair five times in series

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 30, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
