Introduction: Alopecia areata (AA) is an autoimmune disease that causes scalp, face, and/or body hair loss. Recently, oral treatments with kinases inhibition became the first approved therapies for severe AA. An understanding of the use and effectiveness of traditional therapies in real-world treatment settings is needed to guide integration of novel therapies into the treatment paradigm.

Article Synopsis
  • The ALLEGRO study showed that ritlecitinib, a JAK3/TEC inhibitor, is effective and safe for treating alopecia areata in patients aged 12 and older with significant scalp hair loss.
  • A post hoc analysis examined how previous alopecia treatments affected treatment outcomes using the Severity of Alopecia Tool (SALT) in patients taking ritlecitinib.
  • Results indicated that prior use of intralesional corticosteroids improved short-term outcomes, while systemic immunosuppressants worsened them, but overall, previous treatment history did not significantly influence long-term responses to ritlecitinib.

Article Synopsis
  • The EQ-5D-5L is a widely used tool for measuring health-related quality of life, but it has shown limitations in assessing conditions like alopecia areata (AA), particularly regarding its emotional impact from hair loss.
  • This study analyzed data from 612 adults with AA to assess the EQ-5D-5L against other measures, finding that while the EQ-5D-5L had significant ceiling effects, it failed to discern important differences in patients' experiences compared to the more specific Alopecia Areata Patient Priority Outcomes (AAPPO) measure.
  • Overall, the findings suggest that the EQ-5D-5L does not fully capture the quality of life impact

Purpose: Alopecia areata (AA) is an autoimmune-mediated inflammatory dermatological disease characterised by non-scarring hair loss affecting the scalp and sometimes other hair-bearing sites. This study aimed to elicit health state utility values (HSUVs) from the UK general population for AA using time trade off (TTO) interviews.

Methods: Vignette descriptions of health states defined by the extent of hair loss were developed (as well as one describing caregiver burden).

PRODUCTS with janus kinase (JAK) inhibition have been shown to promote hair regrowth in patients with alopecia areata (AA). To guide drug-approval and treatment decisions, it is important to understand patients' willingness to accept the potential risks of JAK inhibition in exchange for potential benefits. We quantified the treatment preferences of adult (≥18 years) and adolescent patients (12-17 years) with AA in the US and Europe to determine the trade-offs they are willing to make between benefits and risks.

Background: The PENELOPE trial investigating efficacy and safety of additional 1-year post-neoadjuvant palbociclib to standard endocrine therapy (ET) high-risk hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) early breast cancer patients failed to improve invasive disease-free survival (iDFS). This analysis compared patient-reported outcomes (PROs) between treatment groups.

Patients And Methods: Patients received 13 cycles of palbociclib 125 mg/day (n = 631) or placebo (n = 619) orally for 3 out of 4 weeks + ET.

Article Synopsis
  • Ritlecitinib showed effectiveness in treating alopecia areata (AA) in a clinical study, with a focus on varying hair loss presentations based on location (e.g., scalp, eyebrows).
  • A group of patients aged 12 and older with significant scalp hair loss participated in the study, and distinct hair loss profiles were identified through latent class analysis based on hair loss severity in different areas.
  • The results indicated that patients taking ritlecitinib (30 and 50 mg) had a significantly higher chance of reporting improvement in hair regrowth and satisfaction compared to those on placebo, regardless of their hair loss profile.

Purpose: Palbociclib was the first cyclin-dependent kinase 4/6 inhibitor approved by the US Food and Drug Administration for use in combination with aromatase inhibitors (AIs) as initial endocrine-based therapy or with fulvestrant in postmenopausal women who previously received endocrine therapy based on data from randomized clinical trials. Real-world studies examining the effectiveness of palbociclib in large, diverse patient populations in routine clinical practice were needed.

Patients And Methods: Ibrance Real World Insights (IRIS) was a retrospective medical record review study of women with confirmed hormone receptor-positive, HER2-negative advanced/metastatic breast cancer treated with palbociclib plus an AI or with palbociclib plus fulvestrant according to approved indications.
