What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
NewGamDrug
Also called Panzyga
In the Dose-evaluation Phase, all patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (0.5, 1.0 or 2.0 g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days). If a patient is randomized to receive the low or medium NewGam dose, the same volume with the same infusion rate as would have been applied in case the patient would have been randomized to 2.0 g/kg NewGam will be used, thus supplemented with an authorized 0.9% w/v isotonic sodium chloride solution as appropriate and detailed in the following infusion bag split to maintain the blinding
| Study group | Role | What they receive |
|---|---|---|
| 0.5 g/kg NewGam | Experimental | All patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (0.5g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days). Receives: Drug: NewGam |
| 1.0 g/kg NewGam | Experimental | All patients will receive a loading dose of 2.0 g/kg Newgam (administered over two consecutive days), followed by seven infusions of the maintenance dose the patient has been randomized to (1.0g/kg NewGam), also administered over two consecutive days every 3 weeks (±4 days). Receives: Drug: NewGam |

What is being measured
The primary outcome is the main question the study is designed to answer.
Decrease in the Inflammatory Neuropathy Cause and Treatment (INCAT) Disability Score
Efficacy - Proportion of responders in the 1.0 g/kg NewGam arm at Week 24 (Termination Visit) relative to baseline (Week 0). A responder being defined as a patient with a decrease of at least 1 point on the adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score (a scale from 0 to 10, from healthy to unable to make any purposeful movements with arms and/or legs)
Measured: at Week 24
Secondary outcomes (11)
Decrease in the Inflammatory Neuropathy Cause and Treatment (INCAT) Disability Score
Proportion of responders in the 0.5 g/kg and 2.0 g/kg NewGam arms at Week 24 relative to baseline compared to the 1.0 g/kg arm, based on the adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score
Measured: at Week 24
Grip Strength Score
Proportion of responders in the 0.5 g/kg and 2.0 g/kg NewGam arms at Week 24 relative to baseline at Week 0 compared to the 1.0 g/kg arm, based on the grip strength (Martin Vigorimeter) using the previously published minimum clinically important difference (MCID) cut-off of 8 kilopascal (kPa)
Measured: at Week 24
Inflammatory Rasch-built Overall Disability Scale (I-RODS Score)
Proportion of responders in the 0.5 g/kg and 2.0 g/kg NewGam arms at Week 24 relative to baseline at Week 0 compared to the 1.0 g/kg arm, based on the Inflammatory Rasch-built overall disability scale (I-RODS Score) using the MCID concept related to the varying standard errors (MCID-SE) as recently demonstrated
Measured: at Week 24
Worsening in the Inflammatory Neuropathy Cause and Treatment (INCAT) Disability Score
Time to first confirmed worsening on the adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale by at least 1 point from the value at baseline (Week 0)
Measured: Week 24
Mean Change in Grip Strength
Mean change from baseline (Week 0) to Termination Visit in grip strength of both hands (assessed by Martin vigorimeter). The reported change was calculated from two time points as the value at the later time point minus the value at the earlier time point.
Measured: Up to 24 weeks
Inflammatory Rasch-built Overall Disability Scale (I-RODS)
Mean change from baseline (Week 0) to Termination Visit in Inflammatory Rasch-built overall disability sum score (I-RODS using the concept of MCID-SE as recently reported) and number of improvers. The reported change was calculated from two time points as the value at the later time point minus the value at the earlier time point.
A scale from 0 to 48, from "Not possible to perform" to "Possible without any difficulty". Higher values represent a better outcome.
Measured: Up to 24 weeks
Motor Nerves
Mean change from baseline (Week 0) to Termination Visit in sum of the distal evoked amplitude of 4 right sided and 4 left sided motor nerves (peroneal, tibial, ulnar and median). The reported change was calculated from two time points as the value at the later time point minus the value at the earlier time point.
Measured: Up to 24 weeks
Mean Change in Pain Intensity Numerical Rating Scale (PI-NRS Scale)
Mean change from baseline (Week 0) to Termination Visit in Pain Intensity Numeric Rating Scale (PI-NRS). The reported change was calculated from two time points as the value at the later time point minus the value at the earlier time point.
The Pain Intensity Numeric Rating Scale (PI-NRS, a numeric scale where 0 = no pain and 10 = worst possible pain) is an 11-point scale for patient self-reporting of pain. A higher value represents a worse outcome.
Measured: Up to 24 weeks
Worsening on the Inflammatory Rasch-built Overall Disability Scale (I-RODS Scale)
Time to first confirmed worsening on the I-RODS scale. The reported change was calculated from two time points as the value at the later time point minus the value at the earlier time point. A scale from 0 to 48, from "Not possible to perform" to "Possible without any difficulty". Higher values represent a better outcome.
Worsening is determined using the concept of MCID (minimum clinically important difference) using the individually obtained standard errors (MCID-SE).
Measured: 24 weeks
1 Point Decrease in the INCAT Disability Score
Time to 1 point decrease (improvement of disability) in adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score
Measured: 24 weeks
Decrease in Inflammatory Rasch-built Overall Disability Scale (I-RODS Scale)
Time to decrease in Inflammatory Rasch-built overall disability scale (I-RODS) scores
Measured: 24 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing NewGam in people with Chronic Inflammatory Demyelinating Poly(Radiculo)Neuropathy, run by Octapharma at 26 sites in 9 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 30 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 16 Feb 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 26 sites in Russia, Ukraine, Czechia, Poland, Romania and 4 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
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 phase mean?
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 16 Feb 2021). 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?
Decrease in the Inflammatory Neuropathy Cause and Treatment (INCAT) Disability Score (time frame: at Week 24). 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 NCT02638207, which also lists 3 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 16 Feb 2021.
