Trial overview
The available trial studies MAGNESIUM L-ASPARTATE HYDROCHLORIDE TRIHYDRATE in people with postoperative hypoparathyroidism after thyroid surgery.[1] The study is called “MAGNEFFICIENT” and it is described as a prospective, randomized, double-blind, placebo-controlled, single-center clinical trial.[1]
The trial is authorised and is listed as a Phase 3 interventional study.[1] The brief summary says the study is testing whether 8-day oral magnesium aspartate can reduce chronic postoperative hypoparathyroidism at 6 months.[1]
Study design and treatment groups
This is a randomized study, which means people are assigned to treatment groups by chance.[1] It is also double-blind, which means the participants and the study team do not know who receives the active treatment or the placebo during the study.[1]
The trial compares two oral treatments: TROFOCARD® max and a placebo that has the same composition as the investigational product except for the active substance.[1] A placebo is a look-alike treatment used to help show whether the study drug makes a real difference.[1]
Who can participate
The study is focused on people with postoperative hypoparathyroidism after thyroid surgery.[1] The source data does not give more detailed entry rules, such as age limits or other medical conditions.[1]
This means the main target population is patients who developed this problem after having their thyroid removed or treated by surgery.[1]
What the trial is measuring
The main endpoint is the incidence of chronic postoperative hypoparathyroidism 6 months after surgery.[1] An endpoint is the main result a clinical trial measures to see if the treatment works.[1]
The trial defines this outcome as persistently low corrected calcium and PTH values when vitamin D or calcium has not been stopped.[1] Corrected calcium is a blood calcium value adjusted to give a more accurate result, and PTH means parathyroid hormone, which helps control calcium levels.[1]
Trial status and size
The trial status is Authorised.[1] The planned enrollment is 500 people, which means the study aims to include 500 participants in total.[1]
The study is single-center, so it is being carried out at one study site.[1] This type of design can help keep the study process consistent across all participants.[1]
