M1P Dipotassium Salt

Clinical trials investigating ALFA-D-MANNOSE 1-PHOSPHATE DIPOTASSIUM are studying GLM101 in people with PMM2-CDG. These trials look at both safety and effectiveness, including changes in ataxia and long-term safety checks in participants who have already received treatment.

Trial overview

Two interventional studies are investigating ALFA-D-MANNOSE 1-PHOSPHATE DIPOTASSIUM through the study drug GLM101 in people with PMM2-CDG.[1][2] Both studies are Phase 2 and are listed as authorised.[1][2]

One study is focused on weekly doses and compares GLM101 with placebo to see whether symptoms of ataxia change after 24 weeks.[1] The other is a long-term study that follows patients who previously received GLM101 to learn more about safety over time.[2]

Who is being studied

The target condition in both trials is PMM2-CDG, which is the only condition named in the source data.[1][2] The long-term study includes patients who already received GLM101 before joining this follow-up study.[2]

The first trial plans to enroll 50 participants, and the long-term study plans to enroll 80 participants.[1][2] This means the research is being done in relatively small groups, which is common in early testing stages.[1][2]

What the trials measure

The main outcome in the weekly-dose study is the change from baseline in ICARS at 24 weeks.[1] Baseline means the starting point before treatment begins, and ICARS is a score used to measure ataxia, which means problems with balance and coordination.[1]

The long-term study mainly collects safety information.[2] This includes side effects, deaths, stopping the study because of side effects, blood and urine tests, ECG results, vital signs, and changes in the physical exam compared with before treatment.[2]

Trial phases and status

Both trials are in Phase 2, which usually means the treatment is being studied in a smaller group of patients to learn more about safety and possible benefit.[1][2] Both studies are marked as authorised in the source data.[1][2]

The first trial is designed to compare GLM101 with placebo, while the second trial follows patients over a longer period with GLM101 exposure already in their history.[1][2] These two designs help researchers look at both short-term effect and longer-term safety.[1][2]

Trial designs and treatment plans

In the first study, participants receive weekly doses of GLM101 or placebo by intravenous administration, which means the treatment is given into a vein.[1] The source data lists the dose as 30 mg/kg for both GLM101 and the placebo infusion description.[1]

In the long-term study, GLM101 is also given by intravenous use.[2] The study is not focused on a new comparison with placebo; instead, it is built to watch what happens over time in patients who have already received the treatment.[2]

Key patient terms

Ataxia means trouble with balance and coordination, which can affect walking and movement.[1]

Placebo means a look-alike treatment used for comparison in a study, so researchers can see whether the study drug has a real effect.[1]

Vital signs are basic health checks such as blood pressure, heart rate, and body temperature.[2]

ECG is a heart tracing test that shows the heart’s electrical activity.[2]

Urinalysis and blood tests help researchers watch for changes in body function during the study.[2]

Glossary

  • PMM2-CDG: A rare condition studied in these trials. The studies focus on people who have this disease.
  • Phase 2: A trial stage that tests a treatment in a smaller group to learn more about how well it works and how safe it is.
  • Interventional study: A study where participants receive a treatment or placebo so researchers can compare results.
  • Placebo: A look-alike treatment with no active study drug. It is used for comparison in research.
  • Ataxia: Problems with balance and coordination.
  • ICARS: A rating scale used to measure ataxia. A change in the score shows whether symptoms got better or worse.
  • Safety information: Details about side effects, serious problems, deaths, and whether people stop the study because of side effects.
  • ECG: A heart tracing test that checks the heart’s electrical activity.
  • Vital signs: Basic body checks such as blood pressure, heart rate, and body temperature.
  • Hematology: Blood tests that help doctors check different parts of the blood.
  • Urinalysis: A urine test used to look for signs of health problems.
