Recruitment
|
|||||||||||||||||||||||||
Recruitment details |
Czech Republic was the only country to participate. The study was initiated on 17 Dec 2018 (First Patient In) and completed on 02 Sep 2020 (Last Patient Out). Subjects were randomly assigned between 26 November 2018 to 11 March 2020 into two groups. | ||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||
Screening details |
Pre-screening took up to 12 months from cytological confirmed ASC-US or LSIL, or histologically confirmed CIN 1, or both before Screening (V1). Randomization was performed in 1:1 ratio (study group (IAD) : control group (wait-and-watch as SOC)); stratification by smoking >10 cigarettes/day. 597 subjects were screened, 171 subjects were enrolled. | ||||||||||||||||||||||||

Arm description |
IAD treatment started after randomization on Day 1. On each treatment cycle, subjects received IAD 3x1g (3x2 tablets 500mg daily) for 2 weeks followed by 2 weeks without treatment and this had to be repeated until the End of Study (V4, i.e., 6 cycles of treatment) or progression. In case of withdrawal for any reason a follow up phone call had to be performed for safety. | ||||||||||||||||||||||||

Dosage and administration details |
Name of Finished Product: Isoprinosine®, Name of Active Ingredient: Inosine acedoben dimepranol.
IAD formulation is a white to off-white tablet containing the active ingredient Inosine acedoben dimepranol (500 mg) and excipients (mannitol, wheat starch, povidone, and magnesium stearate).
The dosage established for one treatment cycle was 3x1g (3x2 tablets 500 mg daily) for 2 weeks (14 days) followed by 2 weeks (14 days) without treatment and this had to be repeated until the end of study or progression. Study treatment had to be taken approximately at the same time every day.
No regimen modifications were established for this study. However, the only modification could have been the discontinuation of treatment according to the investigator’s criteria.

Proportion of subjects with regression of low grade lesions LSIL (CIN I) in 6 months after randomization - Primary analysis | |||||||||
End point description |
Primary variable (regression) as a derived composite variable defined as negativity of both cytological and histological tests. It was a combination of PAP smear test, histological test and COBAS® HPV test.
Summary statistics were calculated by treatment group and by study visit for each component of the primary endpoint.
The analysis of the primary variable reflected the restriction on the randomisation implied by the stratification by study centre. The two-sided 95% CI for the treatment difference was calculated using stratified Newcombe CI for proportion differences with the Cochran-Mantel-Haenszel weights. The adjusted effect was obtained by weighted average of stratum specific rate differences.
Primary analysis was done in Full Analysis Set (FAS), which was as complete as possible and the closest to the intention-to-treat ideal according to ICH E9. Subject was excluded from FAS if she failed in inclusion criterion No. 2 or 3 or there was no data post randomisation available
