Answer Study


Not an actual patient

Let's clear up the facts

Combination treatment has the potential to improve outcomes. For this study, we added ORACEA® (doxycycline, USP) 40mg Capsules to SOOLANTRA® (ivermectin) Cream, 1% to measure efficacy and ensure the treatment approach aims for 'clear'.1 Clear is defined as IGA score of 0 according to the IGA (Investigator Global Assessment) scale, which is commonly used by dermatologists.

Both molecules have independent and cooperative effects on the inflammatory pathways of rosacea.

ANSWER Study Overview11

Study Objective

Evaluate efficacy of ORACEA Capsules plus SOOLANTRA Cream vs SOOLANTRA Cream alone in severe rosacea with papulopustular lesions



Multicenter, randomized, investigator-blinded, parallel-group comparison, 12-week study

†Subjects were provided with non-investigational products, that they were required to use alongside their treatments for the duration of the study. These products were Cetaphil Redness Relieving Foaming Face Wash and Cetaphil Redness Relieving Facial Moisturizer SPF 30.
IGA = Investigator's Global Assessment.

Baseline Characteristics

Patients in two groups were well-ballanced in terms of demographics, skin phototype and severity and duration of disease.

Baseline demographic data11

SD=standard deviation.

Baseline disease characteristics11

Primary Endpoint

Percentage change from baseline in inflammatory lesion counts at week 12.

Safety Data

The combination of SOOLANTRA Cream + ORACEA Capsules treatment resulted in no discontinuations of treatment due to related AEs.

Dual Therapy Demonstrates a Significant Reduction in Inflammatory Lesions from Baseline vs. Monotherapy at Week 1211

Graph showing the mean percentage reduction in IL through week 12. At week 12, dual therapy had an 80.29% mean inflammatory lesion reduction vs. SOOLANTRA Cream + placebo at 73.56%.

Baseline: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138); Week 12: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138)
ITT/LOCF = intention to treat/last observation carried forward.

Dual Therapy Significantly Increased the Percentage of Subjects Achieving 100% Reduction of Inflammatory Lesions by Week 1211

Graph showing that 2x as many subjects on combination therapy achieved 100% lesion reduction vs. monotherapy.

Baseline: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138); Week 12: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138)

66.7% of Subjects (All IGA 4) Achieved Clear/Almost Clear (IGA 0 or 1) With Dual Therapy at Week 1211

Graph showing that 66.7% of patients using combination treatment achieved clear/almost clear at 12 weeks vs. monotherapy at 59.4%.

Baseline: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138); Week 12: SOOLANTRA Cream + ORACEA Capsules (n=135), SOOLANTRA Cream + Placebo (n=138)


Treatment-Related Adverse Events Were Similar in the Two Treatment Arms11

Table showing AEs reported during the ANSWER Study.

In clinical trials with SOOLANTRA Cream, the most common adverse reactions (incidence ≤1%) included skin burning sensation and skin irritation. In controlled clinical studies, the most commonly reported adverse events (>2%) in patients treated with ORACEA Capsules were nasopharyngitis, sinusitis, diarrhea, hypertension and aspartate aminotransferase increase.

*Subjects with at least one event from baseline to end of study. Numbers in columns cannot be added because a given subject may have reported more than one AE.
