Pruritus occurs in all patients with atopic dermatitis and requires quick relief to reduce disease exacerbation and improve quality of life. Crisaborole ointment is a non-steroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis. This post hoc analysis explores crisaborole ointment for early relief of pruritus in patients with mild to moderate atopic dermatitis from 2 phase III studies.

There currently are 3 topical agents approved by the US Food and Drug Administration (FDA) to treat onychomycosis: tavaborole, efinaconazole, and ciclopirox. The phase 3 clinical trial designs for these treatments and their notable differences make it difficult for clinicians to interpret the data into clinical practice. For example, the primary end point predominantly used to assess efficacy in all the trials is complete cure, defined as no involvement of the nail plus mycologic cure; also, a notable number of patients fail to achieve a complete cure despite clear improvement in the nail.

Toenail onychomycosis is a chronic fungal infection that often requires prolonged treatment in order to effectively manage pathogenic organisms and obtain a clear nail. Traditionally, certain clinical features of onychomycosis, including the presence of substantial lateral disease, focal fungal masses, yellow/brown streaks, and extensive nail involvement (ie, >50%), indicate a poor treatment prognosis and have proven difficult-to-treat with oral or traditional topical therapies. Owing to the novel features of topical tavaborole, we sought to understand the potential utility of tavaborole in difficult-to-treat onychomycosis.

Background: Long-term topical treatment is often required for atopic dermatitis (AD), a chronic inflammatory skin disease.

Objective: To assess the long-term safety results from a multicenter, open-label, 48-week safety study (AD-303) of patients (N = 517) ≥2 years of age with mild to moderate AD who continued crisaborole treatment, a topical phosphodiesterase-4 inhibitor, after completing a 28-day phase 3 pivotal study (AD-301, AD-302).

Methods: Global disease severity was assessed in patients every 4 weeks, and if assessed as mild or greater, a 28-day treatment period with crisaborole applied twice daily was initiated.

Purpose: The role of topical antifungal agents in the long-term management of toenail onychomycosis is not well established. The current study evaluated durability of clinical benefit of tavaborole topical solution, 5%, for the treatment of toenail onychomycosis.

Methods: We conducted a pooled analysis of 8-week, post-study follow-up (PSFU) data from two phase 3, randomized controlled trials in a subset of patients who experienced complete or almost clear nail (CN) at the end of treatment (week 52); 48 weeks of treatment with once-daily tavaborole compared with placebo in adults with distal subungual onychomycosis was evaluated at week 60.

Background: Additional topical treatments for atopic dermatitis (AD) are needed that provide relief while minimizing risks.

Objective: We sought to assess the efficacy and safety of crisaborole ointment, a phosphodiesterase 4 inhibitor, in two phase III AD studies (AD-301: NCT02118766; AD-302: NCT02118792).

Methods: Two identically designed, vehicle-controlled, double-blind studies enrolled and randomly assigned (2:1, crisaborole:vehicle) patients aged 2 years or older with an Investigator's Static Global Assessment (ISGA) score of mild or moderate for twice-daily application for 28 days.

Background: Phosphodiesterase-4 (PDE4) is a promising target in atopic dermatitis (AD) treatment. The pharmacokinetics (PK), safety, and efficacy of crisaborole topical ointment, 2% (formerly AN2728) (Anacor Pharmaceuticals, Palo Alto, CA), a boron-based benzoxaborole PDE4 inhibitor, were evaluated in children with mild to moderate AD.

Methods: This phase 1b, open-label, maximal-use study of crisaborole topical ointment, 2% applied twice daily (dose 3 mg/cm(2) ) for 28 days enrolled patients ages 2 to 17 years with extensive AD involving 25% or more or 35% or more treatable body surface area, depending on age.

Onychomycosis is a common and difficult-to-treat fungal infection of the nail unit that gradually leads to dystrophic changes of the nail plate and nail bed. If untreated, infection progresses and may lead to discomfort, reduced quality of life, and risk of complications in patients with comorbid conditions (eg, diabetes, human immunodeficiency virus, peripheral vascular disease). Onychomycosis treatments are designed to eradicate causative pathogens (most commonly Trichophyton rubrum and Trichophyton mentagrophytes), restore healthy nails, and prevent recurrence or spread of infection.

Crisaborole topical ointment, 2% (formerly known as AN2728) is a benzoxaborole, nonsteroidal, topical, anti-inflammatory phosphodiesterase 4 (PDE4) inhibitor investigational compound that recently completed phase 3 studies for the treatment of mild to moderate atopic dermatitis (AD). The unique configuration of boron within the crisaborole molecule enables selective targeting and inhibition of PDE4, an enzyme that converts the intracellular second messenger 3'5'-cyclic adenosine monophosphate (cAMP) into the active metabolite adenosine monophosphate (AMP). By inhibiting PDE4 and thus increasing levels of cAMP, crisaborole controls inflammation.

Importance: Qualitative evidence suggests that hirsutism inflicts significant negative impacts on quality of life and may be associated with depression. Quantitative research is essential to determine best practices in caring for hirsute patients.

Objective: To quantify quality-of-life impact of hirsutism and evaluate how the degree of hirsutism (as assessed by patients and clinicians) is associated with quality of life and depressive symptoms.

Background: Two post hoc analyses assessed the antipruritic activity of crisaborole topical ointment, 2% (crisaborole; Anacor Pharmaceuticals, Inc., Palo Alto, CA), a first-in-class boron-based phosphodiesterase-4 inhibitor in development for treatment of mild to moderate atopic dermatitis (AD).

Methods: Two pooled analyses included data from 4 studies evaluating crisaborole in AD (study 1, phase 1b, systemic exposure, safety, and pharmacokinetics [PK] under maximal-use conditions in children and adolescents; study 2, phase 2a, safety and PK in adolescents; study 3, phase 2a, efficacy and safety in adults; study 4, phase 2, efficacy and safety in adolescents).

Article Synopsis
  • The study focuses on crisaborole, a 2% topical ointment targeting phosphodiesterase-4 (PDE4) for treating mild to moderate atopic dermatitis (AD) in adolescents aged 12 to 17 with specific skin lesions.
  • Twenty-three participants were enrolled in a phase 2a clinical trial where they applied the ointment twice daily for 28 days, demonstrating minimal systemic exposure and a safety profile with most adverse events being mild.
  • Results indicated a significant reduction in AD symptoms and severity, with 35% of patients achieving a notable improvement by the end of the study, suggesting potential effectiveness of the treatment in this age group.

Introduction: Patients with onychomycosis may mask infected nails with polish. Tavaborole topical solution, 5% is a boron-based, small-molecule pharmaceutical approved for the treatment of toenail onychomycosis caused by Trichophyton rubrum and Trichophyton mentagrophytes; efinaconazole topical solution, 10% is approved for the same indication. Nail polish appearance after application of tavaborole (dropper) or efinaconazole (brush); respective applicator appearance; presence of color transfer from respective applicators; and color transfer to remaining solutions after dosing of polished nails were evaluated.

The objective of this study was to explore age-related differences in the reproductive and metabolic manifestations of polycystic ovarian syndrome (PCOS). Using a prospective cross-sectional design, we compared metabolic and reproductive findings in women attending a multidisciplinary clinic for PCOS, stratified across the following age groups: 18-25 (n = 71), 26-35 (n = 129), and 36-45 (n = 29). The study included primarily overweight and obese women, with a mean BMI of 31.
