Introduction:
Tapinarof is a topical aryl hydrocarbon receptor (AhR) agonist in development for the treatment of atopic dermatitis (AD). In two phase 3 trials (ADORING 1 and 2), tapinarof cream 1% once daily (QD) demonstrated significant efficacy and was well tolerated in patients down to age 2 years with AD. Here, we evaluate patient-reported outcomes (PROs), including family impact, with tapinarof in ADORING 1 and 2.
Methods:
In ADORING 1 and 2, 813 patients were randomized to tapinarof or vehicle QD for 8 weeks. PROs were assessed using the Dermatology Life Quality Index (DLQI), Children's Dermatology Life Quality Index (CDLQI), Infants' Dermatitis Quality of Life Index (IDQOL), Dermatitis Family Impact Questionnaire (DFI), and Patient Oriented Eczema Measure (POEM).
Results:
Mean baseline DLQI, CDLQI, IDQOL, and DFI scores indicated that the impact on families and patients' quality of life (QoL) of AD was moderate to very large. Mean POEM scores indicated moderate to severe AD symptoms at baseline. Tapinarof improved QoL versus vehicle across all endpoints at week 8: DLQI, - 6.2 vs - 3.5 (P = 0.0031) and - 5.5 vs - 3.5 (P = 0.0028); DFI, - 5.6 vs - 2.9 (P < 0.0001) and - 5.6 vs - 3.8 (P = 0.0037), in ADORING 1 and 2, respectively. Similar improvements in CDLQI and IDQOL were reported with tapinarof versus vehicle. Tapinarof also significantly improved CDLQI, DFI, and POEM sleep subdomain scores versus vehicle. POEM scores also improved with tapinarof versus vehicle: ≥ 12 years, - 9.4 vs - 5.3 and - 10.6 vs - 3.6 (both P < 0.0001); < 12 years, - 11.4 vs - 5.7 (P < 0.0001), and - 10.8 vs - 7.3 (P = 0.0005).
Conclusions:
Tapinarof significantly improved QoL across PROs, including sleep and family impact, regardless of age, from week 1 (the earliest evaluation) through week 8. Tapinarof is a once-daily, non-steroidal cream that rapidly improves AD symptoms, sleep, and QoL in patients down to age 2 years with AD.

01:17Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
