Study summary

Diabetic foot syndrome is one of the most frequent complications in type 2 diabetic patients. The present work is carried out with the objective of evaluating the use of DIamel combined with insulin in diabetic foot ulcers. Method. Phase II clinical trial. A study group was created that receives the active product and another control group that receives a placebo. Double-blind study with a monthly follow-up for the first 6 months and then quarterly until the end of 1 year. Complementary tests are performed every 6 months to evaluate metabolic, lipid and renal function control.

Inclusion criteria

  • Homeostasis Model Assessment (HOMA) estimates steady state beta cell function (% B) and insulin sensitivity (% S), as percentages of a normal reference population

Exclusion criteria

Exclusion Criteria:

  • Manifestation of to any component of the product
  • Uncooperative patients
  • Severe infection
  • Debilitating diseases
  • treatment
  • Pregnancy
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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Time of healing

    The most important outcome measure is to evaluate the early healing of diabetic foot ulcers with the shape and improvements of the foot ulcers.

    Time frame: 1 year

Secondary outcomes

  1. Glycemic control

    Glucose measures with blood test

    Time frame: 1 year

  2. Lipidic control

    Triglycerides and cholesterol levels with blood test

    Time frame: 1 year

  3. Body mass control

    Body mass test

    Time frame: 1 year

  4. Renal function control

    Renal function measures by Creatinine Clearance Blood Test

    Time frame: 1 year

  5. Insulin control

    Insulin levels measured by the Homeostasis Model Assessment (HOMA) estimates steady state beta cell function (%B) and insulin sensitivity (%S), as percentages of a normal reference population

    Time frame: 1 year

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2014 to primary completion in Nov 2017, 41 months.

Of 31 phase 2 interventional studies under Diabetic Foot, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 47. This study's 41 months is above that.

How these figures are worked out, and which studies are left out of them.

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 Jul 11, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
