This is a repository copy of Efficacy and safety of osilodrostat in patients with Cushing's disease (LINC 3) : a multicentre phase III study with a doubleblind, randomised withdrawal phase.

Background: In a Phase II study, osilodrostat, a potent oral 11β-hydroxylase inhibitor, normalized mean urinary free cortisol (mUFC) in most patients with CD (Fleseriu M et al. Pituitary 2016;19:138-48). We report the efficacy and safety of osilodrostat in a large CD patient population in the first randomized withdrawal Phase III study in this rare, serious disorder (clinicaltrials.gov: NCT02180217). Methods: Phase III, multicenter, double-blind, randomized withdrawal study following a 24-week, open-label, single-arm treatment phase. Open-label osilodrostat was initiated at 2 mg bid in 137 adults with CD and mUFC (mean of three 24-h samples) >1.5xULN (ULN=50.0 µg/24h), with dose adjustments every 2 weeks (dose range 1-30 mg bid) up to week (W) 12 based on efficacy (if mUFC >ULN) and tolerability. At W26, 71 eligible patients (mUFC ≤ULN at W24 without a dose increase after W12) were randomized to continue osilodrostat (n=36) or matching placebo (n=35) for 8 weeks, followed by open-label osilodrostat until W48. Patients who remained on treatment at W26 but were not eligible for randomization continued open-label osilodrostat (n=47). Primary endpoint: patients in each randomized group with mUFC ≤ULN at the end of the randomized withdrawal phase (W34) without a dose increase after W26. For all mUFC assessments, patients who discontinued were classed as non-responders at subsequent time points. Results: At baseline, median (range) mUFC was 3.5xULN (0.3-69.6) in enrolled patients. At the end of the randomized withdrawal period (W34), significantly more patients maintained mUFC ≤ULN (without a dose increase after W26) in the osilodrostat group than in the placebo group (86% vs 29%; OR 13.7, P <0.001). Other endpoints: at W24, 53% of enrolled patients had mUFC ≤ULN without a dose increase after W12 (key secondary endpoint); at W48, 66% of enrolled patients had mUFC ≤ULN; 96% of enrolled patients had mUFC ≤ULN at least once during the study; median time to first mUFC ≤ULN was 41 days. Median (range) duration of osilodrostat exposure was 75 weeks (1-165). By W48, 24 (18%) patients had discontinued the study, 15 (11%) because of AEs. Overall, the most common AEs were nausea (42%), headache (34%) and fatigue (28%). AEs related to hypocortisolism and adrenal-hormone-precursor accumulation occurred in 51% and 42% of patients, respectively. The most common AEs reported in the osilodrostat group during the randomized withdrawal period were nausea (11% vs 0% for placebo), anemia (8% vs 9%), arthralgia (8% vs 0%) and headache (8% vs 0%). Conclusion: Osilodrostat was significantly superior to placebo at maintaining mUFC ≤ULN after randomized withdrawal and normalized mUFC in two-thirds of enrolled patients at W48, with few patients discontinuing treatment because of AEs. This randomized withdrawal study demonstrates osilodrostat to be a highly effective treatment for CD, with good...

The validation of a cosmetic product is performed by physical analyses and sensory assessment. However, the recruitment of panelists takes a long time and is expensive. Moreover, to apply the product on the skin, microbiology analyses and safety are required but may not be not enough to avoid inflammatory reaction on the skin. The solution could be the substitution of sensory evaluation by instrumental measurement to predict the sensory profile before the panel. For the study, thirteen different skin care emulsions based on their composition and texture were carried out simultaneously by 12 expert panelists with a quantitative descriptive sensory evaluation profile and by rheological and textural methods. A statistical methodology was the applied to find correlation trends between both data sets. The methodology confirmed that the correlation between sensory assessment and instrumental parameters is a good solution to save time. The multiple factor analysis (MFA) showed the correlation between firmness with no visual residue attribute and the cohesion with sticky 1 min, which are evident but this methodology could be used for finding more complex correlations not found in literature.
