BackgroundDolutegravir (DTG), a once-daily, human immunodeficiency virus type 1 (HIV-1) integrase inhibitor, was evaluated for distribution and antiviral activity in cerebrospinal fluid (CSF).MethodsING116070 is an ongoing, single-arm, open-label, multicenter study in antiretroviral therapy-naive, HIV-1-infected adults. Subjects received DTG (50 mg) plus abacavir/lamivudine (600/300 mg) once daily. The CSF and plasma (total and unbound) DTG concentrations were measured at weeks 2 and 16. The HIV-1 RNA levels were measured in CSF at baseline and weeks 2 and 16 and in plasma at baseline and weeks 2, 4, 8, 12, and 16.ResultsThirteen white men enrolled in the study; 2 withdrew prematurely, 1 because of a non-drug-related serious adverse event (pharyngitis) and 1 because of lack of treatment efficacy. The median DTG concentrations in CSF were 18 ng/mL (range, 4-23 ng/mL) at week 2 and 13 ng/mL (4-18 ng/mL) at week 16. Ratios of DTG CSF to total plasma concentration were similar to the unbound fraction of DTG in plasma. Median changes from baseline in CSF (n = 11) and plasma (n = 12) HIV-1 RNA were -3.42 and -3.04 log10 copies/mL, respectively. Nine of 11 subjects (82%) had plasma and CSF HIV-1 RNA levels

Introduction Patients with atopic dermatitis (AD) and skin of color can have heterogeneous presentations and treatment responses. In the pivotal phase 3 ADORING 1 and ADORING 2 trials, tapinarof cream 1% once daily (QD) was significantly efficacious and well tolerated versus vehicle in adults and children down to 2 years of age with AD. Objective Here, we report analyses of efficacy by patients' self-identified race and investigator-assessed Fitzpatrick skin type in ADORING 1 and 2. Methods In ADORING 1 and 2, patients with a Validated Investigator Global Assessment for Atopic DermatitisTM (vIGA-ADTM) score of ≥3 (moderate or severe), an Eczema Area and Severity Index score of ≥6, and body surface area involvement of 5–35% were randomized 2:1 to tapinarof cream or vehicle QD for 8 weeks. The primary efficacy endpoint was a vIGA-ADTM score of 0 (clear) or 1 (almost clear) and ≥2-grade improvement from baseline at Week 8. Secondary endpoints included proportion of patients with a ≥75% improvement in Eczema Area and Severity Index (EASI75). Results Of 407 and 406 randomized patients, 8.8–15.3% were Asian, 26.5–35.0% were Black or African American, 44.8–56.8% were White, and 2.7–5.2% were Other groups (including American Indian or Alaska Native, Native Hawaiian or Pacific Islander, or multiple races) across trials. Patients with Fitzpatrick skin types IV, V, and VI represented 23.8–25.1%, 20.6–22.2%, and 7.6–8.9%, respectively, of participants (>50% in both trials). Across trials, vIGA-ADTM responses (ranges) for tapinarof versus vehicle were: Asian, 39.5–48.9% vs 3.7–18.5%; Black or African American, 43.1–47.0% vs 17.5–24.1%; White, 49.4–52.1% vs 12.2–14.5%; and Other, 26.0–44.8% vs 0.0–40.2%. EASI75 responses for tapinarof versus vehicle were: Asian, 47.6–76.6% vs 17.7–20.2%; Black or African American, 48.9–55.3% vs 25.7–30.0%; White, 61.4–67.8% vs 19.6–20.7%; and Other, 38.3–63.3% vs 0.0–40.6%. Similarly, high and consistent vIGA-ADTM and EASI75 responses were reported with tapinarof compared with vehicle for patients with Fitzpatrick skin types I–III and IV–VI. Conclusion Tapinarof cream 1% QD was consistently efficacious among all racial groups and Fitzpatrick skin types, including adults and children down to 2 years of age with skin of color, who comprised approximately 50% of patients in these trials.

Introduction Itch is the most bothersome symptom for patients with atopic dermatitis (AD), and has a significant negative impact on health-related quality of life. Rapid onset of pruritus relief with sustained efficacy is a key outcome for AD therapies. In ADORING 1 and 2, two identical pivotal phase 3, double-blind, vehicle-controlled trials, tapinarof cream 1% once daily (QD) demonstrated efficacy and was well tolerated in adults and children down to 2 years of age with AD. Objective Here, we evaluate time to onset of itch relief in the pivotal phase 3 trials. Methods In ADORING 1 and 2, patients with a Validated Investigator Global Assessment for Atopic DermatitisTM score of ≥3 (moderate or severe), an Eczema Area and Severity Index score of ≥6, and body surface area involvement of 5–35% were randomized 2:1 to tapinarof cream or vehicle QD for 8 weeks. Itch relief was assessed by changes in Peak Pruritus Numerical Rating Scale (PP-NRS) score, daily and by visit, from baseline through Week 8. PP-NRS considers itch over the past 24 hours; lower scores indicate less pruritus. Results 407 and 406 patients were randomized in ADORING 1 and 2. At baseline, mean PP-NRS scores were 6.7 and 6.8 in both trials, respectively. For daily evaluations of itch from baseline, greater reductions in mean PP-NRS scores for tapinarof versus vehicle were observed as early as Day 1, 24 hours after initial application in ADORING 1 (–1.2 vs –0.9), and Day 2 in ADORING 2 (–1.6 vs –1.4). Daily itch improvements continued through Week 8 in both trials. Statistically significant reductions in mean weekly PP-NRS scores occurred as early as Week 1 (earliest assessment) with tapinarof versus vehicle (–2.0 vs –1.2 [ P <0.0001]) and (–2.0 vs –1.3 [ P =0.0010]) in ADORING 1 and 2, respectively. Significantly greater reductions in mean PP-NRS scores with tapinarof versus vehicle were seen for all visits through Week 8 (–4.1 vs –2.6 and –4.1 vs –2.4 [both P<0.0001]). Conclusions Tapinarof cream 1% QD demonstrated rapid, significant, and clinically meaningful pruritus relief from 24 hours after initial application, with improvements increasing through Week 8 in both trials in adults and children down to 2 years with AD.

HIV patients often take drugs for the HIV infection, drugs to prevent opportunistic infections, and other drugs for any other health condition they may have. This may result in drug interactions that may reduce the effectiveness of a drug. A list of web sites with information about drug interactions is included.
