In this severely affected population of Canadians with psoriasis, the physical, mental, social, and financial burden of disease was high.

Background. Levodopa-carbidopa intestinal gel (LCIG) provides continuous levodopa administration and clinical benefits to patients with advanced Parkinson’s disease (PD). This report evaluates long-term safety and efficacy of high-dose LCIG in PD patients. Methods. Data were collected from several prospective, phase III clinical studies and an observational registry. The phase III program (N = 412) included four multicenter studies: a 12-week, randomized, double-blind study and three open-label studies extending ≥12 months. GLORIA (N = 375) was a 24-month, multicountry, observational registry. LCIG safety (adverse effects (AEs)/adverse drug reactions (ADRs)) and efficacy (modified Unified Parkinson’s Disease Rating Scale (UPDRS) part IV item 32 and 39 scores for “On” time with dyskinesia and “Off” time) were assessed in patients who received ≥2000 mg/day vs <2000 mg/day LCIG. Results. A total of 72 of 412 (17.5%) patients required dosages ≥2000 mg/day LCIG in the phase III program and 47 of 375 (12.5%) patients in GLORIA. Baseline demographics and disease severity were similar between dosage groups with more men in the high-dosage group. Compared with the <2000 mg/day dosage group, patients requiring ≥2000 mg/day LCIG had higher rates of AEs/ADRs including polyneuropathy; improvements in “Off” time and discontinuations due to AEs were similar between dosage groups and lower for discontinuations due to ADRs reported in GLORIA. Conclusions. Patients who require ≥2000 mg/day LCIG exhibited a safety profile comparable to the established safety/tolerability of LCIG with similar clinical improvements. Higher AEs were noted but within what is accepted for LCIG. Continuous administration of LCIG is beneficial to advanced PD patients who require very high doses of levodopa.

Background Elagolix is an oral, gonadotropin-releasing hormone (GnRH) receptor antagonist, that significantly reduces dysmenorrhea and non-menstrual pelvic pain (NMPP) in women with moderate to severe endometriosis-associated pain. Methods Data were pooled from two 6-month, placebo-controlled, phase 3 studies (Elaris Endometriosis [EM]-I and II) in which 2 doses of elagolix were evaluated (150 mg once daily and 200 mg twice daily). Pooled data from > 1600 women, aged 18–49, were used to evaluate the efficacy of elagolix and health-related quality of life (HRQoL) in prespecified subgroups of women with various baseline characteristics. Results Of the 1686 women treated, 1285 (76.2%) completed the studies. The percentages of women with clinically meaningful reductions in dysmenorrhea and NMPP were generally consistent by subgroup. Significant treatment by subgroup interaction was demonstrated for dysmenorrhea response in baseline analgesic use (p < 0.01) and previous history of pregnancy (p < 0.05) subgroups, and for NMPP response in the baseline NMPP score (p < 0.05) and history of pregnancy (p < 0.05) subgroups. Patient-reported reduction in pain at month 3 was significant across all subgroups taking elagolix 200 mg BID, and significant across most subgroups with elagolix 150 mg QD. Women across subgroups experienced improvement within each domain of the Endometriosis Health Profile-30 (EHP-30), although significant treatment by subgroup interactions were observed in several categories. Conclusions Elagolix was effective in reducing dysmenorrhea and NMPP, and improving HRQoL, compared with placebo across numerous subgroups of women with various baseline characteristics, covering a broad segment of the endometriosis disease and patient types.
