Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The initial clinical trials for Solagé included 1794 subjects of Skin Type I-V, 94.5% of whom were Caucasian. The trials also included 5% of subjects who were Asian/Pacific Islander (1.2%), African-American (0.8%), and Hispanic/Latino (3.5%).

In the pivotal clinical trials, adverse reactions were primarily mild to moderate in intensity, occurring in 66% and 30% of subjects, respectively. The majority of these events were limited to the skin and 64% had an onset of a skin related adverse reaction early in treatment (by week 8).

The most frequent adverse reactions in subjects treated with Solagé were erythema (49%), burning, stinging, or tingling (26%), desquamation (14%), pruritus (12%), and skin irritation (5%). Some subjects experienced temporary hypopigmentation of treated lesions (5%) or of the skin surrounding treated lesions (7%). Ninety-four of 106 subjects (89%) had resolution of hypopigmentation upon discontinuation of treatment to the lesion, and/or re-instruction on proper application to the lesion only. Another 8% (9/106) of subjects with hypopigmentation events had resolution within 120 days after the end of treatment. Three of the 106 subjects (2.8%) had persistence of hypopigmentation beyond 120 days. Hypopigmentation of the skin surrounding treated lesions occurs even in the setting of proper application of the drug within the lesion border. One subject in the trials, whose brother had vitiligo, experienced hypopigmentation in areas that had not been treated with study medication. Some of these areas continued to worsen for at least one month post treatment with Solagé. Six weeks later the severity of the hypopigmentation had decreased from moderate to mild and 106 days post treatment, subject had resolution of some but not all lesions.

Approximately 6% of subjects discontinued study participation due to adverse reactions. These discontinuations were due primarily to skin redness (erythema) or related cutaneous adverse reactions.

Adverse drug reactions that were reported in greater than 1% of subjects appear in Table 1 below.

Over 150 subjects used Solagé twice daily for 52 weeks in an open label clinical study. The safety profile for Solagé in this long-term study was similar to that seen in the 24-week studies.

Over 90 subjects used Solagé twice daily and a concomitant sunscreen daily for up to 24 weeks in an open label clinical study. The safety profile for Solagé in this study was similar to that seen in studies which prohibited sunscreen use.

An additional open label study was conducted in 259 subjects in the Asian (24.3%), Hispanic/Latino (62.2%), and African American (13.5%) ethnic groups with skin types II to V. This number reflects approximately three times as many subjects in this population as were represented in the initial clinical trials. In this study, as in the earlier studies, Solagé was used twice daily for a period of 24 weeks. The overall safety profile in this study was generally consistent with the initial clinical trials.
