Self-Administered Intralesional Injections for Acne

Not Applicable

Recruiting

• Conditions: Acne Vulgaris
• Interventions: Device: Triamcinolone delivered via injection assistance device

• Registration Number: NCT06186596
• Lead Sponsor: ACOM Labs

Brief Summary

The goal of this clinical trial is to test the safety of intralesional injections of triamcinolone self-administered into acne lesions via an injection assistance device. The main question\[s\] it aims to answer are:

* is use of the injection assistance device safe?

* is delivery of triamcinolone to acne lesions via the injection assistance device efficacious?

Participants will self-inject low dose triamcinolone into acne lesions and track lesion response via photos and survey for 14 days following injection.

Detailed Description

This is an open-label, prospective, single-arm study. Approximately 150 subjects will be enrolled at approximately 3 study sites.

All subjects will receive standard-of-care intralesional injection with triamcinolone using an Injection Assistance Device (i.e., for self-administered intralesional injections) at Visit 1 (Day 1). Subjects will then submit photos via secure photographic app for asynchronous follow up on Day 2 (24-hours post-injection), Day 3 (48-hours post-injection), Day 4 (72-hours post-injection), Day 7, and Day 14.

Efficacy assessments (target lesion assessments) will be conducted remotely by the Investigator at time of each photo submission. Subjects will conduct lesion pain assessments and satisfaction assessments at the time of each remote check-in. Participants will be invited to also have additional photography captured by the study team at the study site or at a location as per participants' convenience.

Arm && Interventions

Group	Intervention	Description
intervention	Triamcinolone delivered via injection assistance device	All subjects will receive standard-of-care intralesional injection with triamcinolone using an Injection Assistance Device (i.e., for self-administered intralesional injections) at Visit 1 (Day 1). Subjects will then submit photos via secure photographic app for asynchronous follow up on Day 2 (24-hours post-injection), Day 3 (48-hours post-injection), Day 4 (72-hours post-injection), Day 7, and Day 14.

Primary Outcome Measures

Name	Time	Method
Incidence of adverse events following device use	14 days	Adverse events associated with device use for 14 days following injection

Secondary Outcome Measures

Name	Time	Method
Subject satisfaction or dissatisfaction with treatment assessed via a 5-grade scale	24 hours - 14 days	Satisfaction or dissatisfaction with will be assessed by the subject using the following subjective 5-grade scale as detailed below. Subject will be instructed: "Rate your level of satisfaction with the effect of study treatment on inflammatory acne lesions by using the following scale": 1. Very satisfied; 2. Satisfied; 3. Neither satisfied nor dissatisfied; 4. Dissatisfied; 5. Very dissatisfied
Target Lesion Pain	14 days	For each inflammatory lesion injected, lesion pain will be assessed by the subject 0 to 10 scale, where 0 is no pain and 10 is worst imaginable pain. Lesion pain at Baseline will be recorded prior to injection(s). The occurrence of inflammatory lesion pain is expected and will not be considered an AE.
Target Lesion Change (subject)	24 hours - 14 days	The subject will assess subjective improvement seen with each target lesion compared to Baseline.; 1. Clear (100%); 2. Almost clear (90% to \<100%); 3. Marked improvement (75% to \<90%); 4. Moderate improvement (50% to \<75%); 5. Fair improvement (25% to \<50%); 6. No change; 7. Worse
Target Lesion Erythema	baseline - 14 days	Investigator will assess severity of erythema for each target lesion on a 0 (no erythema) to 4 (very severe erythema) scale.; 0: No Erythema; 1. Mild Erythema; 2. Moderate Erythema; 3. Severe Erythema; 4. Very Severe Erythema
Target Lesion Severity	baseline - 14 days	Investigator will assess severity of each target lesion on a 0 (none) to 4 (very severe) scale.; 0: None; 1. Mild; 2. Moderate; 3. Severe; 4. Very Severe
Target Lesion Injection Pain	baseline and 5 min following injection	Injection Site Pain during injection will be assessed immediately after the injection of the first target lesion and at 5 minutes post-injection. The occurrence of injection site pain is expected and will not be considered an AE. For each inflammatory lesion injected, lesion pain will be assessed by the subject 0 to 10 scale, where 0 is no pain and 10 is worst imaginable pain.
Target Lesion Change	24 hours - 14 days	Investigator will assess improvement of each target lesion on a 1 (100% clear) to 7 (worse) scale.; 1. Clear (100%); 2. Almost clear (90% to \<100%); 3. Marked improvement (75% to \<90%); 4. Moderate improvement (50% to \<75%); 5. Fair improvement (25% to \<50%); 6. No change; 7. Worse
