Outcome Measures

Primary Outcomes (1)

  • Itch Scale: Visual Analogue Scale Itch (VAS Itch)

    Patients will score the severity of itch on the scale provided at study start, once weekly for 3 months, at the 3-month visit, and again at study end (6 months). Patients will rate their itch from 0 to 10. to measure the intensity of itchiness, where a patient marks a point on a line to indicate how severe their itch is, with zero representing "no itch" and 10 representing "worst imaginable itch." A higher score means a worse outcome.

    baseline, weekly for 3 months, at 3 and 6 months (+/-15 days each timepoint) after start date

Secondary Outcomes (6)

  • The Patient and Observer Scar Assessment Scale 3.0

    baseline, and at clinic visit approximately 3 months (±15 days) after study start

  • Brisbane Burn Scar Impact Panel (BBSIP)

    baseline, and at clinic visit approximately 3 months (±15 days) after study start

  • PROMIS-29

    baseline, and at clinic visit approximately 3 months after study start (±15 days)

  • Pain scale: Visual Analog Scale for Pain (VAS Pain)

    baseline, and at clinic visit approximately 3 months and 6 months after study start (±15 days)

  • Patient Global Impression of Change (PGIC)

    baseline, and at clinic visit approximately 3 months after study start (±15 days)

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Participant has provided informed consent in a manner approved by the IRB and is willing and able to comply with the trial procedures.
  • Adults: ≥18 to \<80 years of age.
  • Has an itchy burn scar.

You may not qualify if:

  • Failure to obtain consent or unable to return for follow up assessments.
  • Patient is unable to follow the protocol required assessments.
  • Member of a vulnerable class (e.g., prisoners, pregnant participant, etc.).
  • Any medical condition that, in the opinion of the investigator or physician, would place the participant at increased risk for participation.
  • Concurrent participation in another interventional clinical trial (to avoid confounding factors that may influence outcomes).
  • History of prior non-compliance or the presence or history of psychiatric condition (including drug or alcohol addiction) that would, in the opinion of the investigator, make it difficult for the participant to comply with the study procedures or follow the investigators instructions.
  • Age \< 18 or ≥ 80 years.
  • Taking one of the following medications: cefuroxime, dasatinib, delavirdine, neratinib, pazopanib, risedronate, or tizanidine.
  • Has a pre-existing inflammatory or itchy skin disease.
  • Is taking an H2 antihistamine for another indication.
