Study summary

The aim of this long-term observational study is the documentation of the use of PASCORBIN® 7.5 g in patients with vitamin C deficiency. Regarding the vitamin C deficiency, the investigators focus on the acquisition of data of the underlying diseases and the reduction of symptoms, that are related to oxidative stress and vitamin-C-deficiency. Next to this, exact assessment of medical tolerance and details of treatment requirements are further aims. Here the investigators take into account acute and chronic underlying medical conditions. Further health economic data are collected.

Read the detailed description

The observational study began on 01 November 2012 and is scheduled for a period of 10 years continued (until 01 November 2022). The duration of the observational study for each patient is not fixed corresponding to the character of a non-interventional study. According to the underlying disease, characterized either acute or chronic, there are 2 and 3 observations within the treatment period, respectively. Documentation comprises the course of the underlying diseases (by tracking of general and diseases-specific symptoms), drug compatibility (by ADR assessment), concomitant medication or other treatment, health economic data, details of treatment regimen and standard epidemiological data.

What researchers measure

Primary outcomes

  1. change in general and disease-specific symptoms

    The main aim was to measure the success of the treatment with Pascorbin® 7.5 g by the documentation of the change in general and disease-specific symptoms. The symptoms are measured by a score: 0 = not present, 1 = slightly, 2 = moderate and 3 = strong The change of the symptoms is measured in change groups: * number of patients with improved symptoms * number of patients with unchanged symptoms * number of patients with worsened symptoms

    Time frame: therapy duration, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

Secondary outcomes

  1. global assessment of efficacy of treatment with PASCORBIN® 7.5 g

    Global assessment of efficacy is measured by a score: * Very good efficacy (complete regression of symptoms) * Good efficacy (symptoms was much improved) * Moderate efficacy (symptoms was slightly improved) * No efficacy (symptoms remained unchanged) * No efficacy (symptoms worsened)

    Time frame: therapy duration, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

  2. Global assessment of tolerability of treatment with PASCORBIN® 7.5 g

    Global assessment of tolerability is measured by a score: * Very good tolerability (no side effects) * Poor tolerability (side effects occurred)

    Time frame: on last visit, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

  3. number of adverse reactions due to PASCORBIN® 7.5 g

    number of adverse reactions due to PASCORBIN® 7.5 g

    Time frame: on last visit, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

  4. epidemiology of the underlying diseases

    number of patients with different underlying diseases due to vitamin C deficiency

    Time frame: on visit 1 (begin of the study) week 1

  5. therapy duration

    measured in weeks or months

    Time frame: time period between first and last infusion an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

  6. dosage scheme

    number of infusions within the therapy duration

    Time frame: therapy duration, an expected average of 3 weeks (for acute diseases) or 12 weeks (for chronic diseases)

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 Apr 26, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
