Outcomes of down-titration in patients with severe scalp alopecia areata initially treated with baricitinib 4-mg: Week 152 data from BRAVE-AA2.

Background: Baricitinib, an oral selective Janus kinase inhibitor, is approved to treat adults with severe alopecia areata (AA).

Objective: To report the week 152 efficacy results from the phase 3 trial BRAVE-AA2 down-titration substudy.

Methods: BRAVE-AA2 enrolled 546 adults with severe AA (Severity of Alopecia Tool [SALT] score ≥50).

Efficacy and Safety of Baricitinib in Patients with Severe Alopecia Areata over 52 Weeks of Continuous Therapy in Two Phase III Trials (BRAVE-AA1 and BRAVE-AA2).

Background: The oral Janus kinase (JAK) inhibitor baricitinib has demonstrated efficacy for severe alopecia areata (AA) over 36 weeks. There are limited data on the longer-term treatment of AA.

Objective: The aim of this study was to evaluate the efficacy and safety of baricitinib for AA in adults with ≥50% scalp hair loss through 52 weeks of continuous therapy in two phase III trials (BRAVE-AA1 and BRAVE-AA2).

Two Phase 3 Trials of Baricitinib for Alopecia Areata.

Background: Alopecia areata is an autoimmune condition characterized by rapid hair loss in the scalp, eyebrows, and eyelashes, for which treatments are limited. Baricitinib, an oral, selective, reversible inhibitor of Janus kinases 1 and 2, may interrupt cytokine signaling implicated in the pathogenesis of alopecia areata.

Methods: We conducted two randomized, placebo-controlled, phase 3 trials (BRAVE-AA1 and BRAVE-AA2) involving adults with severe alopecia areata with a Severity of Alopecia Tool (SALT) score of 50 or higher (range, 0 [no scalp hair loss] to 100 [complete scalp hair loss]).

Androgen receptor expression induces FGF2, FGF-binding protein production, and FGF2 release in prostate carcinoma cells: role of FGF2 in growth, survival, and androgen receptor down-modulation.

Background: Alterations in fibroblast growth factors (FGFs) production and/or FGF receptors expression have been described to play key roles in prostate tumor progression, particularly in androgen-independent tumors. However, the role of androgen receptor (AR) in altering FGF-mediated growth and survival of prostatic neoplastic cells has not been completely defined. In this study, we investigated the alterations in FGF2 production and utilization by the PC3 cell line, after transfection with a full-length AR.
