NCT02290925

Brief Summary

The investigators intend to conduct a triple blind randomized clinical trial to investigate the effect of a biscuit containing herbal extract, available in the market on the fasting blood sugar control in patients with diabetes mellitus and also to find out whether there are any side effects on other vital organs such as kidneys and liver.

Limitations and Caveats

Withdrawing patients needing insulin from the trial compromised the pragmatic nature of the RCT. Blinding of the patients may have been affected because of the slightly different taste and darker nature of the KH biscuit.

Masking Details
Randomization code (A or B) was made using a computer and inserted in a sealed, serially numbered, opaque envelopes. Participants were given a serial number after run-in period. Assistant opened the envelope and assigned the patient to either biscuit A or B. The manufacturers held randomization code. Investigators, patients and those assessing the analysis were masked to the group outcome. Both Kothala Himbutu (KH) and placebo biscuits are identical in size, wrapped in same cover, and packed in identical boxes. The investigators tasted both biscuits and KH biscuits were slightly darker with the same taste. The study product is available in the market. Patients participating in the trial were asked about prior consumption of KH biscuits bought from the market (to exclude contamination). At the end of each period patients were asked whether they could assume the type of biscuit (KH biscuit or placebo) given to them and their preference for the type.
Purpose
TREATMENT
Intervention Model
CROSSOVER
Model Details: Patients with diabetes were screened and Type I Diabetes was excluded. The minimum run-in period was eight weeks and if the variability of HbA1c is more than 20%, excluded, to exclude patients with fluctuating glycaemia. As this is a crossover trial some degree of stability of the glycemic control is necessary to prevent excessive variation of HbA1c interfering with the study outcome. Participants were randomized to receive the KH or placebo biscuit. Oral hypoglycemic was continued and adjusted. Participants consumed KH or placebo biscuit for a period of 3 months as mid-morning and afternoon snack. Subsequently in the washout period of 1 month the participants did not consumed any biscuits. After, crossing over they continued biscuits for another 3 months. HbA1c was done at recruitment, after run-in period, at 3 months and on completion of the study. When there was deterioration of the glycaemic control patient was prescribed insulin, and withdrawn from the study.
