About this study

Official title: A Single Center, Open Label Clinical Trial Investigating the Long-term Efficacy of rhLAMAN (Recombinant Human Alpha-mannosidase or Lamazym) Treatment in Subjects With Alpha-Mannosidosis Who Previously Participated in Lamazym Trials

The overall objective is to evaluate the long-term efficacy of Lamazym i.v. treatment in patients with alpha-Mannosidosis previously enrolled in Lamazym trials and currently receiving the treatment according to the AfterCare Program.

Read the detailed description

The primary objective of the trial is to evaluate the impact of the long-term treatment with Lamazym upon the level of biomarker oligosaccharides in serum and upon the endurance as measured by the change from baseline in the number of steps climbed in 3 minutes (3MSCT).

As secondary objectives, the long term efficacy of Lamazym will be investigated upon endurance as measured by the change from baseline in the number of meters walked in six minutes (6MWT), upon pulmonary function, motor proficiency by BOT-2 and hearing capability by audiometry. In addition, cognitive development will be assessed by Leiter-R test. CNS involvement will be evaluated with MRI/MRS (for patients who previously participated in rhLAMAN-02 trial), CSF biomarkers (Tau, NFL, GFAp) and CSF biomarkers oligosaccharides. Clearance of oligosaccharides in urine will be measured.

Long-term safety and Pharmaco-Kinetic (PK) profile after long-term treatment as measured by rhLAMAN levels in plasma will be assessed as well.

Quality of life will be assessed by questionnaires (CHAQ and EQ-5D-5L).

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Lamazym in people with Alpha-Mannosidosis, run by Zymenex A/S at 1 site in Denmark.

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 4 inclusion and 6 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 20 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 from baseline in reduction of oligosaccharides in serum (time frame: Baseline evaluation prior to first dose compared to evaluation after one, two or four years of treatment). The study lists 2 primary outcomes in all. 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 NCT02478840, which also lists 4 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 20 Nov 2020.
