What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying a skin condition called papulopustular rosacea, which is characterized by redness and bumps on the face. The study will test the effectiveness and safety of a new cream containing ivermectin, a medication used to treat various skin conditions. The trial will compare this new cream to an existing product called Soolantra Cream, which also contains ivermectin, and a cream without ivermectin, referred to as a vehicle.

The purpose of the study is to see how well these creams reduce the number of inflammatory lesions, such as papules and pustules, on the face. Participants will apply one of the creams to their skin over a period of 12 weeks. During this time, the study will monitor changes in the skin condition, including the number of lesions and any side effects experienced by the participants. The study aims to determine which cream is most effective in improving the symptoms of papulopustular rosacea.

Throughout the study, participants will have regular visits to assess their skin condition and overall health. The study will also evaluate the overall success of the treatment and how well participants tolerate the creams. This research will help to better understand the treatment options for papulopustular rosacea and provide valuable information on the safety and effectiveness of the new ivermectin cream compared to existing treatments.

The research process

The trial runs in 6 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, eligibility is confirmed based on specific criteria, including age, diagnosis of papulopustular rosacea, and the number of inflammatory lesions on the face.

    Female participants of childbearing potential must use a highly effective contraceptive method and have a negative pregnancy test before starting the study.

  2. Step 2

    Initial visit and baseline assessment

    During the initial visit, a baseline assessment is conducted. This includes counting the number of inflammatory lesions, such as papules and pustules, on the face.

    The severity of rosacea is evaluated using the Investigator's Global Assessment (IGA) scale.

  3. Step 3

    Treatment phase

    Participants are randomly assigned to receive one of three treatments: Ivermectin 10 mg/g cream, Soolantra® 10 mg/g cream, or a cream without ivermectin (vehicle).

    The cream is applied to the affected areas of the face once daily for a duration of 84 days, with a possible variation of plus or minus 4 days.

  4. Step 4

    Follow-up visits

    Follow-up visits are scheduled at regular intervals to monitor progress and assess changes in the number of inflammatory lesions.

    The severity of rosacea and any changes in facial redness are evaluated at each visit.

  5. Step 5

    Final evaluation

    At the end of the treatment period, a final evaluation is conducted to assess the overall therapeutic success.

    The primary measure of success is the percentage change in the number of inflammatory lesions from the start to the end of the study.

  6. Step 6

    Safety and tolerability assessment

    Throughout the study, any adverse events are recorded to evaluate the safety of the treatments.

    Both the investigator and the participant assess the tolerability of the treatment from the second visit until the end of the study.

Who can join the trial?

7 criteria

  • Women and men who are **18 years of age or older**.
  • Must provide **written consent** to participate in the study after being informed by the study doctor.
  • Must have a **diagnosis of papulopustular rosacea**, which is a skin condition with redness and bumps on the face, according to commonly accepted standards.
  • Must have **15 to 50 inflammatory lesions** on the face, which are red bumps or pus-filled bumps, and no more than 2 of these can be larger bumps called nodules.
  • Must have a **rosacea severity grade** of 3 (moderate) or 4 (severe) as assessed by the study doctor.
  • For all women who can have children: Must use a **highly effective birth control method** throughout the study.
  • For all women who can have children: Must have a **negative urine pregnancy test** before starting the study. The test must be sensitive enough to detect a hormone called **human chorionic gonadotrophin (hCG)** at levels as low as 25 mIU/ml.

Investigated drugs

  • Ivermectin Cream

    is being tested in this study to see how well it works in treating papulopustular rosacea, a skin condition that causes redness and bumps on the face. The cream is applied to the skin and is being compared to another treatment to see if it can reduce the number of inflammatory lesions.

  • Soolantra® Cream

    is the reference treatment in this study. It is also used to treat papulopustular rosacea by reducing inflammation and the number of lesions on the skin. The study aims to compare its effectiveness and safety against the test cream.

What is already known about the treatment

Ivermectin Cream – This medication is applied topically as a cream and is currently being studied for its effectiveness in treating papulopustular rosacea. It is well-documented in medical literature as a treatment option for this skin condition. The main therapeutic indication is to reduce inflammatory lesions associated with rosacea. At the molecular level, ivermectin works by binding to certain channels in nerve and muscle cells of parasites, leading to paralysis and death of the parasites, although its exact mechanism in rosacea is not fully understood. It is classified pharmacologically as an antiparasitic agent.

Investigated diseases

Papulopustular Rosacea – Papulopustular rosacea is a chronic skin condition characterized by redness, swelling, and acne-like breakouts. It primarily affects the central part of the face, including the cheeks, nose, and forehead. The condition progresses with the appearance of small, red, pus-filled bumps called papules and pustules. These lesions can cause discomfort and may be accompanied by a burning or stinging sensation. Over time, the skin may become thickened and develop a rough texture. The condition can fluctuate, with periods of flare-ups and remission.
