General information about the trial
|
|||
Main objective of the trial |
The primary objective of the study was to determine the efficacy of LL-37, at concentrations of 0.5 and 1.6 mg/mL, in increasing the incidence of complete wound closure compared with placebo in the treatment of hard-to-heal (HTH) venous leg ulcers (VLUs).
|
||
Protection of trial subjects |
The study was performed in accordance with the ethical principles that have their origin in the Declaration of Helsinki that are consistent with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH)/Good Clinical Practice (GCP) and applicable regulatory requirements. Informed consent was obtained from all patients prior to initiation of the study.
Pain was part of efficacy assessment and was monitored throughout the study using a graded visual analogue scale (VAS) score (0-10).
Safety was monitored at all visits based on adverse events (AEs) and local tolerability assessments. The investigator and/or delegated study nurse carefully monitored the treated ulcers with regard to ulcer characteristics at each dressing change, 2 times per week. In order to detect drug-related reactions, patients reported any AEs occuring between dressing changes.
Cream containing lidocaine or prilocaine could be used for pain relief before cleansing and dressing both on the wound itself and in surrounding tissues.
|
||
Background therapy |
No background therapy was used in the study. | ||
Evidence for comparator |
No comparator was used in the study. The test product was compared to a placebo. | ||

Recruitment
|
|||||||||||||||||||||||||||||||||||||||||
Recruitment details |
The first patient was screened and treated in the run-in period on 2018-09-26. The first patient was randomised and treated (during the treatment period) on 2018-10-15. The last patient’s last visit (treatment period) was on 2020 03-20 and the last patient’s last folow-up visit was on 2020-07-13. | ||||||||||||||||||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||||||||||||||||||
Screening details |
Screening was performed in 190 patients. Of those, 149 were randomised. The main reason for screening failure was unfulfilment of inclusion/exclusion criteria. One randomised patient withdrew consent and the remaining 148 paitents entered and completed the run-in period, during which they were treated with placebo and received standart ulcer care. | ||||||||||||||||||||||||||||||||||||||||

Notes [1] - Period 1 is not the baseline period. It is expected that period 1 will be the baseline period. Justification: One patient withdrew after randomisation and before treating. Therefore the total number of patints for whom baseline characteristics are reported is 148; 48 in the LL37 0.5 mg/mL group, 49 in the LL37 1.6 mg/mL group and 51 in the placebo group. By selecting Period 2-Ttreatment period as the baseline period, the correct number of patients is entered in the baseline characteristics report. |

Patients who were randomised in violation of eligibility criteria were excluded from the FAS. The blinding ensured that the decision of whether to begin treatment could not be influenced by knowledge of the assigned treatment, and thus the intention-to-treat principle was preserved despite the exclusion of patients who did not receive any application of the study treatment. The same rationale applied to the exclusion of patients with no post-baseline ulcer assessment, since the first such assessment was performed within a few days after baseline. Analysis on the FAS was based on the planned treatment (i.e. patients were analysed “as randomised”).

Confirmed complete wound closure of the target ulcer-estimated proportion of responders (FAS) | ||||||||||||||||||||
End point description |
The primary efficacy endpoint was a confirmed complete wound closure of the target ulcer, defined as skin re-epithelialisation without drainage or dressing requirements at any time up to the end-of-treatment visit at 13 weeks, which was sustained at the post-wound closure visit, 2 weeks after the first reported closure. The Investigator assessed at each visit whether complete wound closure of the target ulcer had been achieved. The wound closure was always to be documented by photography, both when first recorded and when confirmed 2 weeks later. At the post-wound closure visits, 2 weeks after the complete wound closure was first reported, the Investigator assessed whether the complete wound closure was confirmed. Post-wound closure visits could be conducted at any time point during the treatment period after the wound was assessed as closed.
Note that the estimated proportion of responders is based on the statistical model (logistic regression analysis) and adjusted for covariates.

Wound healing rate of the target ulcer, FAS | ||||||||||||||||||||
End point description |
The wound healing rate for each patient was estimated by fitting an exponential decay model with 2 parameters to the wound area measurements over time.
Only wound area measurements during the treatment period (including the baseline measurement at randomisation) were considered for the modelling. For patients for whom the wound reopened after complete wound closure, only measurements up to and including the first time of wound closure were included in the model. Patients with less than 4 measurements were excluded from the analysis.
Wound area measurements were performed at Visits 1, 3 and 6 (Run-in period), Visits 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32 (Treatment period) and at Visits 37 and 38 (follow-up period).

End point description |
Time to confirmed complete wound closure was analysed using a regression analysis to estimate the restricted mean survival time (RMST). The model included treatment group and the baseline area of the target ulcer (dichotomous stratification factor) as factors, and the duration of the target ulcer at baseline as a covariate.
For patients completing the treatment period or being prematurely withdrawn from the study without experiencing confirmed complete wound closure (including patients for whom the wound reopened during the post-wound closure visits), the time to event was right-censored at the date of end of treatment/ withdrawal.

The primary efficacy endpoint was a confirmed complete wound closure of the target ulcer, defined as skin re-epithelialisation without drainage or dressing requirements at any time up to the end-of-treatment visit at 13 weeks, which was sustained at the post-wound closure visit, 2 weeks after the first reported closure.
The Investigator assessed at each visit whether complete wound closure of the target ulcer had been achieved. The wound closure was always to be documented by photography, both when first recorded and when confirmed 2 weeks later. At the post-wound closure visits, 2 weeks after the complete wound closure was first reported, the Investigator assessed whether the complete wound closure was confirmed.

For patients completing the treatment period or being prematurely withdrawn from the study without experiencing confirmed complete wound closure (including patients for whom the wound reopened during the post-wound closure visits), the time to event was right-censored at the date of end of treatment/ withdrawal.

The first CSP version under which patients were included in the study was version 1.0 (dated 2018 03-01).
After this, there was one protocol amendment in the study, resulting in CSP version 2.0 (dated 2018 06-11). Changes included sample time point correction, clarification of description of blinding and unblinding, as well as clarification that patients with missing data should be considered as non-responders in the main analysis on the full analysis set, upon request from the Swedish competent authorities.
