Study summary

The purpose of this study is to assess the efficacy of Diamel (dietary supplement) administration in the treatment of patients with type 2 diabetes receiving insulin therapy. The duration of this double-blind placebo controlled phase 3 clinical trial will be 24 weeks. The estimated number of patients to be recruited and randomized for the study is 116. Daily insulin requirements, blood glucose (fasting and post-prandial) concentrations, glycosylated hemoglobin (HbA1c), triglycerides and cholesterol will be assessed at the beginning and after 24 weeks of treatment.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

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 29, 2011, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
