A Phase II Randomized Study of Subcutaneous Ixekizumab, an Anti–Interleukin-17 Monoclonal Antibody, in Rheumatoid Arthritis Patients Who Were Naive to Biologic Agents or Had an Inadequate Response to Tumor Necrosis Factor Inhibitors†

Abstract: Objective To evaluate ixekizumab, an anti–interleukin-17A (anti–IL-17A) monoclonal antibody, in 2 populations of rheumatoid arthritis (RA) patients: biologics-naive patients and patients with an inadequate response to tumor necrosis factor (TNF) inhibitors. Methods In this phase II, randomized, double-blind study, placebo or ixekizumab was administered subcutaneously to 260 biologics-naive patients and 188 patients with an inadequate response to TNF inhibitors at weeks 0, 1, 2, 4, 6, 8, and 10 with concomitant disease-modifying antirheumatic drugs. The primary objective was to determine the dose-response relationship of ixekizumab as measured by the proportion of biologics-naive patients meeting the American College of Rheumatology 20% improvement criteria (ACR20) at week 12. Results Using a logistic regression model defined a priori, a statistically significant dose-response relationship as measured by ACR20 response rates at week 12 was detected in biologics-naive patients (P = 0.031). For patients with an inadequate response to TNF inhibitors, ACR20 responses at week 12 were significantly better with ixekizumab than placebo (P < 0.05). Decreases in the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP), Clinical Disease Activity Index (CDAI), and CRP level from baseline were observed at week 12 in the ixekizumab groups in both populations (P < 0.05 versus placebo). Onset of action was rapid in some dose groups in both populations, with improvements in the ACR20, DAS28-CRP, CRP levels, and CDAI observed by day 3 (P < 0.05). Adverse events occurred with similar frequencies overall in the ixekizumab and placebo groups. Infections were more frequent with ixekizumab than placebo (biologics-naive 25% versus 19%; inadequate responders to TNF inhibitors 27% versus 25%). No mycobacterial or invasive fungal infections were reported. Conclusion Ixekizumab improved RA signs and symptoms in RA patients who were either naive to biologics treatment or had an inadequate response to TNF inhibitors. The safety profile was similar to that of other biologic agents, with no unexpected safety concerns.

Lasmiditan is an effective acute treatment for migraine: A phase 3 randomized study.

Abstract: Objective To assess the efficacy and safety of lasmiditan in the acute treatment of migraine. Methods Adult patients with migraine were randomized (1:1:1) to a double-blind dose of oral lasmiditan 200 mg, lasmiditan 100 mg, or placebo and were asked to treat their next migraine attack within 4 hours of onset. Over 48 hours after dosing, patients used an electronic diary to record headache pain and the presence of nausea, phonophobia, and photophobia, one of which was designated their most bothersome symptom (MBS). Results Of the 1,856 patients who treated an attack, 77.9% had ≥1 cardiovascular risk factors in addition to migraine. Compared with placebo, more patients dosed with lasmiditan 200 mg were free of headache pain at 2 hours after dosing (32.2% vs 15.3%; odds ratio [OR] 2.6, 95% confidence interval [CI] 2.0–3.6, p p p p Conclusions Lasmiditan dosed at 200 and 100 mg was efficacious and well tolerated in the treatment of acute migraine among patients with a high level of cardiovascular risk factors. ClinicalTrials.gov identifier NCT02439320. Classification of evidence This study provides Class I evidence that for adult patients with migraine, lasmiditan increases the proportion of subjects who are headache pain free at 2 hours after treating a migraine attack.

Orally Bioavailable GSK-3α/β Dual Inhibitor Increases Markers of Cellular Differentiation In Vitro and Bone Mass In Vivo

Abstract: UNLABELLED: GSK-3, a component of the canonical Wnt signaling pathway, is implicated in regulation of bone mass. The effect of a small molecule GSK-3 inhibitor was evaluated in pre-osteoblasts and in osteopenic rats. GSK-3 inhibitor induced osteoblast differentiation in vitro and increased markers of bone formation in vitro and in vivo with concomitant increased bone mass and strength in rats. INTRODUCTION: Inactivation of glycogen synthase kinase -3 (GSK-3) leads to stabilization, accumulation, and translocation of beta-catenin into the nucleus to activate downstream Wnt target genes. To examine whether GSK-3 directly regulates bone formation and mass we evaluated the effect of 603281-31-8, a small molecule GSK-3 alpha/beta dual inhibitor in preosteoblastic cells and in osteopenic rats. MATERIALS AND METHODS: Murine mesenchymal C3H10T1/2 cells were treated with GSK-3 inhibitor (603281-31-8) and assayed for beta-catenin levels, activity of Wnt-responsive promoter, expression of mRNA for bone formation, and adipogenic markers and alkaline phosphatase activity. In vivo, 6-month-old rats were ovariectomized (OVX), allowed to lose bone for 1 month, and treated with GSK-3 inhibitor at 3 mg/kg/day orally for 60 days. At the end of treatment, BMD was measured by DXA, bone formation rate by histomorphometry, vertebral strength (failure in compression), and the expression levels of osteoblast-related genes by real-time PCR. RESULTS: Treatment of C3H10T1/2 cells with the GSK-3 inhibitor increased the levels of beta-catenin accompanied by activation of Wnt-responsive TBE6-luciferase reporter gene. This was associated with an increased expression of mRNA for bone sialoprotein (1.4-fold), collagen alpha1 (I) (approximately 2-fold), osteocalcin (1.2-fold), collagen alpha1(V) (1.5-fold), alkaline phosphatase (approximately 160-fold), and runx2 (1.6-fold), markers of the osteoblast phenotype and bone formation activity. Alkaline phosphatase mRNA expression paralleled alkaline phosphatase activity. The mRNA levels of collagens alpha1 (I), alpha1 (V), biglycan, osteonectin, and runx-2 increased on treatment with the GSK-3 inhibitor in rat femur compared with the OVX control. DXA analyses revealed significant increases in BMC and BMD in cancellous and cortical bone of OVX rats treated with GSK-3 inhibitor. This was associated with increased strength (peak load, energy, and stiffness) assessed by lumbar vertebra load to failure in compression. Histomorphometric analyses showed that 603281-31-8 robustly increased bone formation but did not exclude a small effect on osteoclasts (resorption). CONCLUSIONS: An orally active, small molecule GSK-3 inhibitor induced osteoblast differentiation and increased markers of bone formation in vitro, and increased markers of bone formation, bone mass, and strength in vivo, consistent with a role for the canonical Wnt pathway in osteogenesis.
