General information about the trial
|
|||
Main objective of the trial |
To compare the glycaemic control after 8 weeks of treatment with oral insulin 338 in aGIPET® I tablet formulation versus s.c. insulin glargine, when both are administered once daily in combination with metformin ± DPP-4 inhibitor in subjects with T2DM inadequately controlled on oral antidiabetic therapy
|
||
Protection of trial subjects |
The trial was conducted in accordance with the Declaration of Helsinki (2013) and ICH Good Clinical Practice (1996). The trial was conducted in accordance with FDA 21 CFR 312.120.
|
||
Background therapy |
The non-investigational medicinal products in this trial were metformin and dipeptidyl-peptidase-4 (DPP-4) inhibitor (oral administration). The background treatment was open-label throughout the trial and subjects received their usual medication per prescription from their primary physician. | ||

Pre-assignment
|
||||||||||||||||
Screening details |
A 2-week run-in period: to avoid carryover effects from discontinued oral anti-diabetic treatment prior to randomisation and to ensure adequate time to achieve stable glycaemic control for evaluation of hypoglycaemia and pharmacodynamics effect. A maximum daily/tolerated dose of metformin±DPP-4 inhibitor was unchanged during the run-in period. | |||||||||||||||

Blinding implementation details |
A double-blind trial; treatment was blinded by all subjects receiving active and placebo treatment. All tablets and solutions (active or placebo) were visually identical to ensure blinding. The trial drugs were packed blinded at Novo Nordisk A/S. The dumas were blinded within tablet strengths (i.e. a similar package for a duma with 900 nmol oral insulin 338 and a duma with oral placebo, etc.). A vial cover was used to blind the s.c. insulin glargine (Lantus®) and the placebo vial

Oral Insulin 338 | |||||||||||||||
Arm description |
Insulin 338/placebo (matched to insulin glargine - 10 ml) were taken orally/subcutaneously once daily for 8 weeks. The insulin dose was adjusted once weekly using the same titration algorithm as for the comparator (assuming that 2,700 nmol oral insulin 388 corresponded to 10 units s.c. insulin glargine) and was based on the mean of 3 preceding daily pre-dose self-measured plasma glucose (SMPG) values on 3 consecutive days. The starting dose for oral insulin 338 was 2,700 nmol (a lower starting dose of 900-1,350 nmol could be selected at the discretion of the investigator) and the maximum allowed daily dose was 16,200 nmol. Subjects continued pre-trial metformin with or without DPP-4 inhibitor throughout the entire trial. | |||||||||||||||

A maximum daily dose of 16,200 nmol oral insulin 338 was allowed.

Statistical analysis description |
The results are from MMRM analysis from day 7, 14, 21, 28, 35, 42, 49, 55 and 56 with treatment and strata as factors and baseline FPG as a covariate, all nested within day. An unstructured covariance matrix describes the variability for the repeated measurements for a subject. The residual variance is depending on treatment. The treatment difference refers to "oral insulin 338 minus subcutaneous insulin glargine. There were 50 subjects, rather than 48 subjects contributing to this analysis.

1. Implementation of additional information in the protocol on local effects of oral insulin 338 in the gastro-intestinal tract. 2. Implementation of severe hypoglycaemic episodes as withdrawal criteria in protocol. 3. Revision of the subject information/informed consent form to include more information on local effects of oral insulin 338 in the gastro-intestinal tract. 4. Revision of the subject information/informed consent form changing the wording from “a large proportion” to “many” subjects with T2DM. 5. Revision of the subject information/informed consent form to include an explanation of the relationship between doses of oral insulin 338 (given in nmol) and s.c.insulin glargine (given in units). |

Limitations and caveats |

Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Analysis of pharmacokinetic data: the anti-drug antibody formation influence on the insulin 338 assay performances could not be ruled out. Also, insulin 338 and insulin glargine are different chemical entities and they should not be compared directly |
