NCT04614415 | Unknown

• 1 other identifier: LQ5I-19-01
• Study Type: interventional
• Target: 78
• Locations: 1 country
• Sites: 4

Brief Summary

The study includes two study groups, one involves treatment with auto-cross-linked Hyaluronic acid by intralesional and hypodermic injection, repeated after two weeks (T14), while the control arm provides an equal treatment but with isotonic saline solution. Enrolled patients will be randomized into 2 groups with an allocation of 2:1 in study treatment arm and control arm respectively. They will be evaluated using the POSAS scale before the treatment and re-evaluated at 30, 90 and 180 days after treatment. The scar evaluation will be completed by an ultrasound assessment at time 0 (T0), 30 (T30), T90 and T180 and the DLQI (Dermatology Life Quality Index) to be assessed at time 0 (T0), 30 (T30), 90 (T90) and 180 (T180). In subjects that will consent, a small surgical biopsy for an explorative evaluation of the scar tissue will be performed before (T0) and after treatment (T30) for a histological assessment.

Conditions

Hypertrophic Scar

Outcome Measures

Primary Outcomes (1)

• Change from baseline to Day 90 in POSAS total score for Observer

  The performance of two injections of IAL-SYSTEM ACP in improving the quality of the scar after 90 days from the first treatment in patients with hypertrophic scars will be evaluated by the mean change from baseline to Day 90 in POSAS total score for Observer.

  90 days after treatment

Secondary Outcomes (4)

• To evaluate the performance of IAL-SYSTEM ACP in improving the quality of the scar

  after 30 and 180 days from the first treatment

• To assess the changing in the Quality of life after 30, 90 and 180 days from the first treatment with the Dermatology Life Quality Index (DLQI)

  after 30, 90 and 180 days from the first treatment

• To assess the changing in the dermal volume after 30, 90 and 180 days from the first treatment

  after 30, 90 and 180 days

• Safety of the treatment. Number of patients with treatment related adverse events

  throug clinical investigation completion, an average one year

Study Arms (2)

Treatment group

EXPERIMENTAL

group 1 will be treated with autocrosslinked Hyaluronic acid

Device: Autocrosslinked Hyaluronic aid

control group

PLACEBO COMPARATOR

group 2 treated with placebo (isotonic saline solution).

Other: placebo

Interventions

Autocrosslinked Hyaluronic aid DEVICE

IAL-SYSTEM ACP gel is an auto-cross-linked HA derivative in the form of highly viscous gel. In this direct formation of ester linkages no foreign substances are introduced into the molecule, thus catabolism of ACP leads only to HA

Also known as: IAL SYSTEM ACP

Treatment group

placebo OTHER

The placebo consists in an isotonic saline solution (NaCl 0.9%)

control group
