Comparative safety of different recommended doses of sodium-glucose cotransporter 2 inhibitors in patients with type 2 diabetes mellitus: a systematic review and network meta-analysis of randomized clinical trials.

Objective: The safety results of different recommended doses of sodium-glucose cotransporter 2 inhibitors (SGLT-2i) for patients with type 2 diabetes mellitus (T2DM) remain uncertain. This study aims to comprehensively estimate and rank the relative safety outcomes with different doses of SGLT-2i for T2DM. Methods: PubMed, Embase, the Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Chinese National Knowledge Infrastructure, WanFang database, and SinoMed database were searched from the inception to 31 May 2023. We included double-blind randomized controlled trials (RCTs) comparing SGLT-2i with placebo or another antihyperglycemic as oral monotherapy in the adults with a diagnosis of T2DM. Results: Twenty-five RCTs with 12,990 patients randomly assigned to 10 pharmacological interventions and placebo were included. Regarding genital infections (GI), all SGLT-2i, except for ertugliflozin and ipragliflozin, were associated with a higher risk of GI compared to placebo. Empagliflozin 10mg/d (88.2%, odds ratio [OR] 7.90, 95% credible interval [CrI] 3.39 to 22.08) may be the riskiest, followed by empagliflozin 25mg/d (83.4%, OR 7.22, 95%CrI 3.11 to 20.04)) and canagliflozin 300mg/d (70.8%, OR 5.33, 95%CrI 2.25 to 13.83) based on probability rankings. Additionally, dapagliflozin 10mg/d ranked highest for urinary tract infections (UTI, OR 2.11, 95%CrI 1.20 to 3.79, 87.2%), renal impairment (80.7%), and nasopharyngitis (81.6%) when compared to placebo and other treatments. No increased risk of harm was observed with different doses of SGLT-2i regarding hypoglycemia, acute kidney injury, diabetic ketoacidosis, or fracture. Further subgroup analysis by gender revealed no significantly increased risk of UTI. Dapagliflozin 10mg/d (91.9%) and canagliflozin 300mg/d (88.8%) ranked first in the female and male subgroups, respectively, according to the probability rankings for GI. Conclusion: Current evidence indicated that SGLT-2i did not significantly increase the risk of harm when comparing different doses, except for dapagliflozin 10mg/d, which showed an increased risk of UTI and may be associated with a higher risk of renal impairment and nasopharyngitis. Additionally, compared with placebo and metformin, the risk of GI was notably elevated for empagliflozin 10mg/d, canagliflozin 300mg/d, and dapagliflozin 10mg/d. However, it is important to note that further well-designed RCTs with larger sample sizes are necessary to verify and optimize the current body of evidence.

Randomized controlled trial of KW-6356 monotherapy in patients with early untreated Parkinson's disease.

INTRODUCTION: KW-6356 is a novel selective adenosine A2A receptor antagonist/inverse agonist. We evaluated the efficacy and safety of KW-6356 as monotherapy in patients with early, untreated Parkinson's disease (PD). METHODS: This was a randomized, placebo-controlled, double-blind study conducted in Japan to investigate the efficacy and safety of once-daily KW-6356 (3 or 6 mg/day) orally administered as monotherapy for 12 weeks in patients with early PD (NCT02939391). The primary endpoint was the least squares means of change from baseline in the MDS-UPDRS Part III total score. RESULTS: Overall, 168 patients were randomized and treated (KW-6356 3 mg/day n = 55; 6 mg/day n = 58, placebo n = 55); Week 12 completion rates were >90% per group. LS mean [95% CI] changes from baseline to Week 12 in MDS-UPDRS Part III total scores were -5.37 [-7.25, -3.48] for 3 mg/day, -4.76 [-6.55, -2.96] for 6 mg/day and -3.14 [-4.97, -1.30] for placebo. Changes from baseline were larger for both KW-6356 groups than for the placebo group at all time points. Secondary endpoints supported the primary findings with larger changes in MDS-UPDRS Part II, Parts II + III, and Total scores in the KW-6356 groups than in the placebo group. Treatment was well-tolerated; the most common treatment-emergent adverse events with KW-6356 were constipation (n = 4 [7.3%] and n = 6 [10.3%] in the 3 and 6 mg/day groups, respectively) followed by nasopharyngitis (n = 4 [7.3%] and n = 5 [8.6%] in the 3 and 6 mg/day groups, respectively). CONCLUSION: KW-6356 monotherapy is well tolerated and more effective than placebo in patients with early, untreated PD.

Real-world safety profile of eculizumab in patients with paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, or generalized myasthenia gravis: an integrated analysis of post-marketing surveillance in Japan.

Eculizumab is a C5 inhibitor approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and anti-acetylcholine receptor antibody-positive generalized myasthenia gravis (AChR + gMG) in Japan. We report integrated safety data from post-marketing surveillance in these three indications, focusing on commonly occurring adverse events (AEs) and infection-related AEs. Of 1219 patients registered, 1055 (PNH: 780; aHUS: 192; AChR + gMG: 83) had available safety data. Total eculizumab exposure was 3977.361 patient-years. AEs were reported in 74.03% of patients. AEs with an incidence of  ≥ 1.0 per 100 patient-years included hemolysis, headache, nasopharyngitis, renal impairment, anemia, pneumonia, upper respiratory tract inflammation, influenza, condition aggravated, and infection. The incidence of infection-related AEs was 21.30 per 100 patient-years, the most frequent types (≥ 1.0 per 100 patient-years) being nasopharyngitis, pneumonia, influenza, and infection. Meningococcal infections were reported in four patients (0.10 per 100 patient-years). Two patients died from meningococcal sepsis, with a mortality rate of 0.05 per 100 patient-years. This is the largest safety dataset on eculizumab in Japan derived from more than 10 years of clinical experience. No new safety signals were observed and the safety profile of eculizumab was consistent with that in previous clinical trials and international real-world safety analyses.

Long-Term Safety and Tolerability During a Clinical Trial and Open-Label Extension of Low-Sodium Oxybate in Participants with Narcolepsy with Cataplexy.

BACKGROUND: The safety and efficacy of low-sodium oxybate (LXB; Xywav®) were established in a randomized, double-blind, placebo-controlled, phase 3 withdrawal study in adults with narcolepsy with cataplexy; however, the longer-term safety profile has not yet been examined. The aim of the current analysis was to assess the time of onset and duration of common treatment-emergent adverse events (TEAEs) for LXB throughout the open-label optimized treatment and titration period (OLOTTP) and the stable dose period (SDP) portions of the main study, and the subsequent 24-week open-label extension (OLE). METHODS: In a double-blind, placebo-controlled, randomized withdrawal trial of LXB, TEAEs were evaluated during the 12-week OLOTTP, the 2-week SDP, and the subsequent 24-week OLE. Eligible participants were aged 18-70 years with a diagnosis of narcolepsy with cataplexy. At study entry, participants were taking sodium oxybate (SXB) alone, SXB with other anticataplectics, other anticataplectics alone, or were anticataplectic-treatment naive; other anticataplectics were tapered and discontinued during the OLOTTP. All participants initiated LXB during week 1 of the OLOTTP, and their dose was individually titrated based on safety and efficacy. Following the main study period, participants entered the OLE after rescreening (re-entry) after discontinuing LXB treatment or directly after completing the main study (rollover). TEAEs were assessed in the safety population as of database lock. TEAE duration was defined as time from TEAE start date to end date (or end of SDP or OLE, if end date was unrecorded). RESULTS: The safety population included 201 participants (SXB alone, n = 52; SXB with other anticataplectics, n = 23; other anticataplectics alone, n = 36; anticataplectic-treatment naive, n = 90). During the OLOTTP/SDP, headache was the most common LXB-emergent TEAE overall (71 events; n = 42 (21%); median (range) duration = 1 (1-147) day), followed by nausea (31 events; n = 26 (13%); median (range) duration = 9 (1-54) days) and dizziness (26 events; n = 21 (10%); median (range) duration = 7 (1-117) days). Among the 74 participants in the OLE, the most commonly reported TEAEs were headache (14 events; n = 7, 9%; peak incidence month 3 (n = 5/72); median (range) duration = 1 (1‒25) day), dizziness (8 events; n = 5, 7%; peak incidence month 1 (n = 3/74); median (range) duration = 26 (1‒181) days), and nasopharyngitis (6 events; n = 6, 8%; peak incidence month 6 (n = 2/69); median (range) duration = 9 (1‒24) days). Overall, study discontinuations attributed to TEAEs were 21/65 (32%) during the OLOTTP and SDP and 3/7 (43%) during the OLE. CONCLUSIONS: In this long-term analysis, the safety and tolerability profile of LXB was generally consistent with the known safety profile of SXB. During the OLOTTP and SDP, most TEAEs occurred early and were generally of short duration. TEAE prevalence decreased throughout the duration of the OLE; the most common TEAEs reported during the OLE were headache, dizziness, and nasopharyngitis. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT03030599 (25 January 2017).

Low-sodium oxybate (LXB) is a medicine for narcolepsy. LXB treats daytime sleepiness and cataplexy (sudden muscle weakness). LXB is like sodium oxybate (SXB) but has 92% less sodium. This study looked at side effects in people taking LXB for many months. Three study periods were looked at in this report. In period 1, people could change their LXB dose for 12 weeks. This was to find their best dose. In period 2, people took that same best dose for 2 weeks. In period 3, some people kept taking LXB for 24 weeks. This was to study the longer-term effects. Everyone knew that they were taking LXB. During periods 1 and 2, the most common side effect was headache. Nausea and dizziness were also common. During period 3, headache was also the most common side effect. Dizziness and nasopharyngitis were also common. Nasopharyngitis is a cold in the nose and throat. In periods 1 and 2, most side effects happened early on. They also ended quickly. Fewer side effects happened in period 3. Among people leaving the study early, 32% left because of side effects during periods 1 and 2. During period 3, 43% left because of side effects. Overall, long-term side effects in people taking LXB were similar to those seen with SXB.

Secukinumab long-term efficacy and safety in psoriasis through to year 5 of treatment: results of a randomized extension of the phase III ERASURE and FIXTURE trials.

BACKGROUND: In the long-term extension study of the ERASURE and FIXTURE trials, the efficacy of secukinumab (a fully human anti-interleukin-17A monoclonal antibody) was demonstrated to have been maintained through to year 3 of treatment in moderate-to-severe plaque psoriasis. OBJECTIVES: To assess the efficacy and safety of secukinumab through to year 5 of treatment in moderate-to-severe plaque psoriasis. METHODS: Responders with ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) from two core trials - ERASURE and FIXTURE - were randomized 2 : 1 at year 1 (end of core trials) to either the same dose (300 or 150 mg, continuous treatment) or placebo (treatment withdrawal) every 4 weeks, until year 3 or relapse (> 50% reduction in maximal PASI from core study baseline). Partial responders (achieving PASI 50 but not PASI 75) at year 1 continued at the same dose as in the core trials. At year 3, all patients received open-label secukinumab treatment, with those on secukinumab 300 mg continuing on their dose, while those on secukinumab 150 mg or placebo received secukinumab 150 or 300 mg based on the physician's discretion. The study is registered on ClinicalTrials.gov with the identifier NCT01544595. RESULTS: Most patients randomized to placebo at year 1 relapsed, but the response was rapidly recaptured upon reinitiation of treatment. PASI responses were sustained with secukinumab through to year 5. The PASI responses for the 300 mg responders + partial responders group at year 1 (PASI 75/90/100: 86.8%/72.8%/45.9%) trended downwards until year 3 (PASI 75/90/100: 82.3%/58.4%/32.7%) and then remained stable through year 4 (PASI 75/90/100: 83.3%/60.1%/32.2%) until year 5 (PASI 75/90/100: 81.1%/62.8%/35.1%). Dermatology Life Quality Index showed sustained benefit up to year 5. Absolute PASI responses were maintained throughout the study. The most common adverse events (AEs) were infections and infestations, nasopharyngitis, and upper respiratory tract infections (URTIs). The overall exposure-adjusted incidence rate (EAIR; with 95% confidence interval) for all AEs was 139.9 (130.3-149.9). EAIRs for Crohn's disease and neutropenia were 0.1 (0.0-0.3) and 0.5 (0.3-0.8), respectively. CONCLUSIONS: The 4-year extension of two pivotal phase III trials demonstrated that secukinumab treatment was effective through to year 5 and improved quality of life in patients with moderate-to-severe plaque psoriasis. The most common AEs were infections and infestations, nasopharyngitis, and URTIs. The safety profile was consistent with that in the secukinumab phase II/III clinical development programme.

Safety and tolerability of spesolimab in patients with ulcerative colitis.

BACKGROUND: Interleukin (IL)-36 signaling has been shown to be increased in ulcerative colitis (UC). Spesolimab, a novel humanized monoclonal antibody, targets the IL-36 pathway. RESEARCH DESIGN AND METHODS: We report safety, immunogenicity, and efficacy data of intravenous (IV) spesolimab in UC. Study 1: phase II, randomized, placebo-controlled trial (300 mg single dose; 450 mg every 4 weeks [q4w]; or 1,200 mg q4w, three doses). Study 2: phase IIa, randomized, placebo-controlled trial (1,200 mg q4w). Study 3: phase IIa, open-label, single-arm trial (1,200 mg q4w). Studies lasted 12 weeks, with a 12-, 24-, and 16-week safety follow-up, respectively. RESULTS: Adver+se event (AE) rates were similar for spesolimab and placebo in Studies 1 (N = 98; 64.9%; 65.2%) and 2 (N = 22; 86.7%; 71.4%); all patients in Study 3 (N = 8) experienced AEs. The most frequent investigator-assessed drug-related (spesolimab; placebo) AEs were skin rash (5.4%; 0%) and nasopharyngitis (4.1%; 0%) in Study 1; acne (13.3%; 0%) in Study 2; one patient reported skin rash, nasopharyngitis, headache, and acne in Study 3. Efficacy endpoints were not met. CONCLUSIONS: Spesolimab was generally well tolerated, with no unexpected safety concerns. The safety data are consistent with studies in other inflammatory diseases.

Risk of infections of biological and targeted drugs in patients with spondyloarthritis: meta-analysis of randomized clinical trials.

BACKGROUND: Concerns exist regarding the risk of infections in patients with spondyloarthritis (SpA) treated with biologics. We assessed the risk of infections of biological and targeted drugs in patients with SpA by performing a meta-analysis based on randomized controlled trials (RCTs). METHODS: A systematic literature search was conducted in PubMed, Embase, Web of Science, the Cochrane Library, and China Biology Medicine Disc for RCTs evaluating the risk of infections of biological therapy in patients with SpA from inception through August 9, 2021. We calculated a pooled Peto odds ratio (OR) for infections in biologics-treated patients vs. placebo patients. The risk of bias on the included RCTs was assessed by using the Cochrane Risk of Bias Tool. RESULTS: In total, 62 studies were included in this meta-analysis. Overall, the risk of infection (Peto OR: 1.16, 95% confidence interval [CI]: 1.07-1.26, P < 0.001), serious infection (Peto OR: 1.65, 95% CI: 1.26-2.17, P < 0.001), upper respiratory tract infection (URTI) (Peto OR: 1.17, 95% CI: 1.04-1.32, P = 0.008), nasopharyngitis (Peto OR: 1.25, 95% CI: 1.10-1.42, P < 0.001), and Candida infection (Peto OR: 2.64, 95% CI: 1.48-4.71, P  = 0.001) were increased in SpA patients treated with biologics compared with placebo. Sensitivity analysis based on biologics classes was conducted, and results demonstrated that compared with placebo, there was a higher risk of infection for tumor necrosis factor (TNF)-a inhibitors (Peto OR: 1.38, 95% CI: 1.13-1.68, P  = 0.001) and interleukin (IL)-17 inhibitors (Peto OR: 1.55, 95% CI: 1.08-2.22, P  = 0.018) in axial SpA, and for Janus kinase inhibitors in peripheral SpA (Peto OR: 1.39, 95% CI: 1.14-1.69, P  = 0.001); higher risk of serious infection for IL-17 inhibitors in peripheral SpA (Peto OR: 3.46, 95% CI: 1.26-9.55, P = 0.016) and axial SpA (Peto OR: 2.01, 95% CI: 1.38-2.91, P < 0.001); higher risk of URTI for TNF-a inhibitors in axial SpA (Peto OR: 1.37, 95% CI: 1.05-1.78, P = 0.019), and for apremilast in peripheral SpA (Peto OR: 1.60, 95% CI: 1.08-2.36, P = 0.018); higher risk of nasopharyngitis for TNF-a inhibitors in axial SpA (Peto OR: 1.41, 95% CI: 1.05-1.90, P = 0.022) and peripheral SpA (Peto OR: 1.49, 95% CI: 1.09-2.05, P = 0.013), and for IL-17 inhibitors in axial SpA (Peto OR: 1.35, 95% CI: 1.01-1.82, P = 0.044); higher risk of herpes zoster for Janus kinase inhibitors in peripheral SpA (Peto OR: 2.18, 95% CI: 1.03-4.62, P = 0.043); higher risk of Candida infection for IL-17 inhibitors in peripheral SpA (Peto OR: 2.52, 95% CI: 1.31-4.84, P = 0.006). CONCLUSIONS: This meta-analysis shows that biological therapy in patients with SpA may increase the risk of infections, including serious infections, URTI, nasopharyngitis, and Candida infection, which should be paid attention to in our clinical practice.

Evaluating Upadacitinib in the Treatment of Moderate-to-Severe Active Ulcerative Colitis: Design, Development, and Potential Position in Therapy.

Upadacitinib is a selective small molecule that inhibits Janus kinase (JAK) type 1. This molecule is administrated orally and is currently approved for the treatment of rheumatoid arthritis, atopic dermatitis, and psoriatic arthritis. Upadacitinib has been approved by the United States Food and Drug Administration for the induction and maintenance therapy of moderate-to-severe ulcerative colitis (UC) and is under investigation by the European Medicines Agency. Data from two induction and two maintenance Phase III randomized controlled trials (RCTs) proved the efficacy of upadacitinib in achieving clinical and endoscopic remission in patients with moderate-to-severe UC, regardless of previous inadequate response to other biologic therapies. The most frequently reported adverse events in the induction trials were acne, creatine phosphokinase increase, nasopharyngitis, headache, and anemia, while in the maintenance studies nasopharyngitis, elevation of creatine phosphokinase, UC exacerbation, upper respiratory tract infection, arthralgia, and anemia were reported. A limited proportion of upadacitinib-treated patients experienced adverse events of special interest, like herpes zoster infections or thromboembolic events, indicating a reliable safety profile. The aim of this review is to summarize the available evidence on upadacitinib in UC providing useful insights about the positioning of this drug in the therapeutic algorithm.

Efficacy and safety of baricitinib in combination with topical corticosteroids in patients with moderate-to-severe atopic dermatitis with inadequate response, intolerance or contraindication to ciclosporin: results from a randomized, placebo-controlled, phase III clinical trial (BREEZE-AD4).

BACKGROUND: Baricitinib, an oral selective Janus kinase (JAK)1 and JAK 2 inhibitor, was shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis (AD). OBJECTIVES: To evaluate the efficacy and safety of baricitinib with background topical corticosteroids (TCS) in patients with moderate-to-severe AD and inadequate response, intolerance or contraindication to ciclosporin A (CA). METHODS: In this double-blind, randomized, placebo-controlled, phase III study, patients were randomized 1: 1: 2: 1 to placebo (N = 93), baricitinib 1 mg (N = 93), 2 mg (N = 185) or 4 mg (N = 92) with background TCS. The primary endpoint was the proportion of patients receiving baricitinib 4 mg or 2 mg (+ TCS) vs. placebo + TCS who achieved ≥ 75% improvement from baseline in the Eczema Area and Severity Index (EASI 75) at week 16. RESULTS: Baricitinib 4 mg + TCS was superior to placebo + TCS for EASI 75 (4 mg: 32%, placebo: 17%, P = 0·031) at week 16 and for improvements in itch, skin pain and number of night-time awakenings owing to itch. Improvements were maintained through 52 weeks of treatment. Treatment-emergent adverse events (TEAEs) were more common with baricitinib than placebo (+ TCS); most were mild or moderate. The most frequent TEAEs with baricitinib 4 mg + TCS were nasopharyngitis, herpes simplex, influenza and headache. No deaths or deep vein thromboses were reported. CONCLUSIONS: Baricitinib 4 mg + TCS improved the signs and symptoms of moderate-to-severe AD through 52 weeks of treatment in patients with inadequate response, intolerance or contraindication to CA. The safety profile was consistent with previous studies of baricitinib in moderate-to-severe AD. What is already known about this topic? Ciclosporin A is indicated for the treatment of atopic dermatitis that is refractory to topical therapies. However, its use is limited by safety concerns and it may not provide adequate response for some patients. Baricitinib, an oral selective Janus kinase (JAK)1 and JAK2 inhibitor, has been shown to improve the signs and symptoms of moderate-to-severe atopic dermatitis as a monotherapy or in combination with topical corticosteroids. What does this study add? Baricitinib combined with background low- or moderate-potency topical corticosteroids provided improvements in the signs and symptoms of moderate-to-severe atopic dermatitis through 1 year of treatment in patients with a contraindication, intolerance or failure to respond to ciclosporin A. The most common treatment-emergent adverse events with baricitinib 4 mg were nasopharyngitis, herpes simplex, influenza and headache. The safety profile was consistent with previous studies in patients with moderate-to-severe atopic dermatitis.

Long-term safety and tolerability of eptinezumab in patients with chronic migraine: a 2-year, open-label, phase 3 trial.

BACKGROUND: Eptinezumab, an anti-calcitonin gene-related peptide monoclonal antibody recently approved in the United States for preventive treatment of migraine in adults, was found to be well tolerated in double-blind, placebo-controlled studies in patients with episodic and chronic migraine. The objective of the PREVAIL study was to evaluate the long-term safety, immunogenicity, and impact on patient-reported outcomes of repeat doses of eptinezumab in patients with chronic migraine. METHODS: PREVAIL was an open-label, phase 3 trial comprising a 48-week treatment phase followed by a second 48-week treatment phase. Adults with chronic migraine received eptinezumab 300 mg by 30-min intravenous administration every 12 weeks for up to 8 doses. Patients were followed for 20 weeks after the final infusion (end-of-study visit at week 104). RESULTS: Overall, 128 adults (mean age, 41.5 years) with chronic migraine were included. During the 2 years, the most frequently reported treatment-emergent adverse events were nasopharyngitis (14.1%), upper respiratory tract infection (7.8%), sinusitis (7.8%), influenza (6.3%), bronchitis (5.5%), and migraine (5.5%). The rate of study-drug discontinuation due to adverse events was 6.3%, which included 3 patients with infusion-related hypersensitivity. The incidence of anti-eptinezumab antibodies peaked at week 24 and declined despite continued dosing, to nondetectable levels at week 104. Improvements in patient-reported outcomes were observed at first assessment (week 4) and generally sustained through week 104. CONCLUSION: In adults with chronic migraine, eptinezumab 300 mg demonstrated a favorable safety profile, limited long-term immunogenicity, early and sustained reductions in migraine-related burden, and improvements in health-related quality of life over 2 years.

Long-Term Safety and Efficacy of Anifrolumab in Adults With Systemic Lupus Erythematosus: Results of a Phase II Open-Label Extension Study.

OBJECTIVE: To investigate long-term safety and tolerability of anifrolumab, a human monoclonal antibody to the type I interferon (IFN) receptor subunit 1, in patients with moderate-to-severe systemic lupus erythematosus (SLE). METHODS: This 3-year, multinational, open-label extension study included adult patients who completed treatment (48 weeks of anifrolumab or placebo; 12-week follow-up) in the MUSE phase IIb randomized controlled trial (RCT). Patients initially received 1,000 mg of anifrolumab intravenously every 4 weeks, which was reduced to 300 mg every 4 weeks based on the benefit/risk profile established in the MUSE trial. Adverse events (AEs) were assessed monthly. Exploratory end points included the SLE Disease Activity Index 2000 (SLEDAI-2K), Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI), pharmacodynamics, and health-related quality of life (HRQoL). RESULTS: Of the 246 patients who completed the RCT, 218 (88.6%) enrolled in the open-label extension study, of which 139 (63.8%) completed 3 years of treatment. Approximately 69.7% of patients reported ≥1 AE during the first year of open-label extension treatment. Frequency and patterns of serious AEs and AEs of special interest over 3 years were consistent with those reported for 1 year of treatment in the RCT. Few patients (6.9%) discontinued treatment due to AEs. No new safety signals were identified. Improvement in the SLEDAI-2K was sustained over 3 years. SDI and Short Form 36 health survey scores remained stable. Neutralization of type I IFN gene signatures was maintained in the IFN-high population, and C3, C4, and anti-double-stranded DNA showed trends toward sustained improvement. CONCLUSION: Long-term anifrolumab treatment demonstrates an acceptable safety profile with sustained improvement in SLE disease activity, HRQoL, and serologic measures.

Efficacy and Safety of Baricitinib Combined With Topical Corticosteroids for Treatment of Moderate to Severe Atopic Dermatitis: A Randomized Clinical Trial.

Importance: Baricitinib, an oral selective Janus kinase 1 and 2 inhibitor, effectively reduced disease severity in moderate to severe atopic dermatitis (AD) in 2 phase 3 monotherapy studies. Objective: To assess the efficacy and safety of 4 mg and 2 mg of baricitinib in combination with background topical corticosteroid (TCS) therapy in adults with moderate to severe AD who previously had an inadequate response to TCS therapy. Design, Setting, and Participants: This double-blind, placebo-controlled, phase 3 randomized clinical trial, BREEZE-AD7 (Study of Baricitinib [LY3009104] in Combination With Topical Corticosteroids in Adults With Moderate to Severe Atopic Dermatitis) was conducted from November 16, 2018, to August 22, 2019, at 68 centers across 10 countries in Asia, Australia, Europe, and South America. Patients 18 years or older with moderate to severe AD and an inadequate response to TCSs were included. After completing the study, patients were followed up for up to 4 weeks or enrolled in a long-term extension study. Interventions: Patients were randomly assigned (1:1:1) to receive 2 mg of baricitinib once daily (n = 109), 4 mg of baricitinib once daily (n = 111), or placebo (n = 109) for 16 weeks. The use of low-to-moderate potency TCSs was allowed. Main Outcomes and Measures: The primary end point was the proportion of patients achieving a validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD) score of 0 (clear) or 1 (almost clear), with a 2-point or greater improvement from baseline at week 16. Results: Among 329 patients (mean [SD] age, 33.8 [12.4] years; 216 [66%] male), at week 16, a vIGA-AD score of 0 (clear) or 1 (almost clear) was achieved by 34 patients (31%) receiving 4 mg of baricitinib and 26 (24%) receiving 2 mg of baricitinib compared with 16 (15%) receiving placebo (odds ratio vs placebo, 2.8 [95% CI, 1.4-5.6]; P = .004 for the 4-mg group; 1.9 [95% CI, 0.9-3.9]; P = .08 for the 2-mg group). Treatment-emergent adverse events were reported in 64 of 111 patients (58%) in the 4-mg group, 61 of 109 patients (56%) in the 2-mg group, and 41 of 108 patients (38%) in the placebo group. Serious adverse events were reported in 4 patients (4%) in the 4-mg group, 2 (2%) in the 2-mg group, and 4 (4%) in the placebo group. The most common adverse events were nasopharyngitis, upper respiratory tract infections, and folliculitis. Conclusions and Relevance: A dose of 4 mg of baricitinib in combination with background TCS therapy significantly improved the signs and symptoms of moderate to severe AD, with a safety profile consistent with previous studies of baricitinib in AD.

Dupilumab Provides Favorable Safety and Sustained Efficacy for up to 3 Years in an Open-Label Study of Adults with Moderate-to-Severe Atopic Dermatitis.

BACKGROUND: Management of moderate-to-severe atopic dermatitis (AD) commonly requires long-term treatment. OBJECTIVE: The aim of this study was to report the safety and efficacy of dupilumab treatment for up to 3 years in adults with moderate-to-severe AD. METHODS: This ongoing, multicenter, open-label extension study (LIBERTY AD OLE; NCT01949311) assessed dupilumab treatment in adults previously enrolled in dupilumab trials. Patients received dupilumab 300 mg weekly up to 148 weeks. The primary outcome was safety. RESULTS: Of 2677 patients enrolled and treated, 347 reached week 148. Mean self-reported drug compliance was 98.2%. Safety data were consistent with previously reported trials (270.1 adverse events [AEs]/100 patient-years; 6.9 serious AEs/100 patient-years) and the known dupilumab safety profile. Common AEs (≥ 5% of patients) included nasopharyngitis, AD, upper respiratory tract infection, conjunctivitis, headache, oral herpes, and injection-site reactions. AD signs and symptoms showed sustained improvements during treatment with mean (standard deviation, mean percentage change from parent study baseline) Eczema Area and Severity Index 1.4 (3.2, - 95.4%) and weekly Pruritus Numerical Rating Scale 2.2 (1.8, - 65.4%) at week 148. LIMITATIONS: No control arm; fewer patients at later time points; regimen different from the approved 300 mg every 2 weeks dose. CONCLUSION: These safety and efficacy results support dupilumab as a continuous long-term treatment for adults with moderate-to-severe AD. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01949311. Dupilumab provides favorable safety and sustained efficacy for up to 3 years in an open-label study of adults with moderate-to-severe atopic dermatitis (MP4  139831 kb).

Phase 3, Randomized, Double-Blind, Active-Comparator (Darbepoetin Alfa) Study of Oral Roxadustat in CKD Patients with Anemia on Hemodialysis in Japan.

BACKGROUND: Roxadustat is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor approved in China for dialysis-dependent CKD anemia. METHODS: This phase 3, 24-week, double-blind, double-dummy study evaluated roxadustat's noninferiority to darbepoetin alfa for hemodialysis-dependent CKD anemia. We randomly assigned Japanese patients to oral roxadustat three times weekly or to darbepoetin alfa injections once weekly, titrating doses to maintain hemoglobin between 10-12 g/dl. The primary end point was change of average hemoglobin from baseline to weeks 18-24 (∆Hb18-24). Secondary end points were average hemoglobin and proportion of patients with hemoglobin between 10-12 g/dl (maintenance rate) at weeks 18-24, and iron parameters. Safety assessments included treatment-emergent adverse events and adjudicated ophthalmologic findings. RESULTS: We randomly assigned 303 patients to roxadustat (n=151) or darbepoetin alfa (n=152). The difference between roxadustat and darbepoetin alfa in ∆Hb18-24 was -0.02 g/dl (95% confidence interval, -0.18 to 0.15), confirming roxadustat's noninferiority to darbepoetin alfa. Average hemoglobin at weeks 18-24 with roxadustat was 10.99 g/dl (95% confidence interval: 10.88 to 11.10), confirming its efficacy. Among patients with one or more hemoglobin value during weeks 18-24, the maintenance rate was 95.2% with roxadustat and 91.3% with darbepoetin alfa. Serum iron, ferritin, and transferrin saturation remained clinically stable with roxadustat; transferrin and total iron binding capacity increased through week 4 before stabilizing. Common treatment-emergent adverse events were nasopharyngitis, shunt stenosis, diarrhea, contusion, and vomiting. The proportion of patients with new or worsening retinal hemorrhage was 32.4% with roxadustat and 36.6% with darbepoetin alfa. We observed no clinically meaningful changes in retinal thickness groups. CONCLUSIONS: Roxadustat maintained hemoglobin within 10-12 g/dl in patients on hemodialysis and was noninferior to darbepoetin alfa. Treatment-emergent adverse events were consistent with previous reports.

Ten years with biosimilar rhGH in clinical practice in Sweden - experience from the prospective PATRO children and adult studies.

BACKGROUND: In 2007, Omnitrope® was the first biosimilar recombinant human growth hormone (rhGH) to be approved in Sweden for treatment in adults and children. Over 10 years' safety and effectiveness data for biosimilar rhGH can now be presented. METHODS: PATRO Children and PATRO Adults are multicenter, longitudinal, observational, post-marketing surveillance studies. Eligible patients include children 0-18 years and adults receiving biosimilar rhGH treatment. Adverse events (AEs) are monitored for safety evaluation. Growth variables in children and metabolic data in adults are recorded for effectiveness evaluation. RESULTS: As of January 2019, data from 136 children (48% male) were reported from Swedish centers. Mean age in rhGH treatment-naïve patients at study entry (n = 114) was 7.5 years, with mean 3.6 years treatment duration. No severe AEs of diabetes, impaired glucose tolerance, or malignancy were reported. The most frequently reported AE was nasopharyngitis (n = 16 patients). No clinically relevant anti-hGH or neutralizing antibodies were observed. The mean change from baseline in height standard deviation score (SDS) in naïve prepubertal GH deficiency patients was + 0.79 at 1 year, + 1.27 at 2 years, and + 1.55 at 3 years. Data from 293 adults (44% rhGH-naïve, 51% male) were included. Fatigue was the most frequently reported AE (n = 26 patients). The incidence of new neoplasms or existing neoplasm progression was 23.8 patients per 1000 patient-years. Type 2 diabetes mellitus was reported in four patients. At baseline in rhGH-naïve adults, mean (SD) body mass index (BMI) was 29.1 (5.6) kg/m2 and mean (SD) insulin-like growth factor (IGF)-I SDS was - 3.0 (1.4). Mean daily dose increased from 0.1 mg at baseline to 0.3 mg after 4 years. IGF-I SDS normalized during the first year of treatment. Mean BMI and glucose were unchanged over 4 years, while low-/high-density lipoprotein cholesterol ratio decreased. CONCLUSIONS: For the first time, Swedish data from the PATRO Children and Adults studies are presented. The 10-year data suggest that biosimilar rhGH is well tolerated across pediatric and adult indications. Safety and effectiveness were similar to previous reports for other rhGH preparations. These results need to be confirmed in larger cohorts, highlighting the importance of long-term post-marketing studies.

Long-term safety of brodalumab in Japanese patients with plaque psoriasis: An open-label extension study.

Brodalumab, an interleukin-17 receptor A inhibitor, demonstrated rapid and robust efficacy with a favorable safety profile in patients with moderate to severe plaque psoriasis. Here, we present data from a multicenter, open-label extension study in patients with plaque psoriasis with/without psoriatic arthritis who completed 64 weeks of treatment with brodalumab (140 or 210 mg, every 2 weeks [Q2W]). Patients were enrolled to evaluate the long-term safety and efficacy of a modified dose of brodalumab. Eligible patients were switched to a reduced dose of brodalumab (140 mg every 4 weeks on day 1) in the extension study; the dose and dosing interval were modified sequentially at the physician's discretion (minimum 140 mg every 8 weeks and maximum 210 mg Q2W) until drug approval, after which all patients were switched to 210 mg Q2W for postmarketing surveillance. Of the 129 patients enrolled, 107 (82.9%) completed the 108-week or more extension study. All patients had psoriasis that was well controlled with brodalumab treatment on day 1. Improvement in psoriasis-related symptoms, evaluated with the Psoriasis Area and Severity Index, Psoriasis Scalp Severity Index, Dermatology Life Quality Index, Nail Psoriasis Severity Index, and American College of Rheumatology 20, 50 and 70, was maintained during the 108-week extension study. Brodalumab treatment was well tolerated throughout, and no new safety signals were identified. The most commonly reported treatment-related adverse event was nasopharyngitis, followed by influenza and oral candidiasis. No cases of serious candida infection or Crohn's disease were observed in this study. Serious treatment-related adverse events, such as appendicitis, brain abscess, bacterial meningitis, colon cancer, immunoglobulin A nephropathy and tubulointerstitial nephritis, were reported in one patient each. No anti-brodalumab-binding antibodies or brodalumab-neutralizing antibodies were detected in any patient throughout the extension study. Overall, the long-term efficacy and safety of brodalumab were demonstrated over 108 weeks.

Safety and effectiveness of peficitinib (ASP015K) in patients with rheumatoid arthritis: interim data (22.7 months mean peficitinib treatment) from a long-term, open-label extension study in Japan, Korea, and Taiwan.

BACKGROUND: Peficitinib (ASP015K), a novel oral Janus kinase inhibitor, has demonstrated efficacy and safety for the treatment of rheumatoid arthritis (RA) in randomized, controlled trials of up to 52 weeks' duration. However, safety and effectiveness after long-term treatment have not been assessed. METHODS: This was an interim analysis of an ongoing open-label, multicenter extension study in RA patients who completed phase 2b (RAJ1; 12 weeks) and phase 3 (RAJ3 and RAJ4; 52 weeks) peficitinib studies in Asia (mainly Japan). Eligible patients (n = 843) received oral peficitinib once daily (100 mg, or 50 mg for patients transferring from RAJ1). The peficitinib dose could be increased (up to 150 mg) or reduced (to 50 mg) at the discretion of the investigator. Efficacy variables assessed included American College of Rheumatology (ACR) response rates, ACR components, and disease activity score in 28 joints based on C-reactive protein (DAS28-CRP). RESULTS: Results up to May 2018 are summarized. Mean peficitinib duration of exposure was 22.7 months and the maximum dose was 100 mg in most (66.5%) patients. ACR responses were maintained during the extension study, with ACR20/50/70 response rates of 71.6%, 52.1%, and 34.7% at week 0 and 78.9%, 61.4%, and 42.7% at end of treatment, respectively. ACR components and DAS28-CRP showed improvements from baselines of the preceding studies and continued to show improvements during the extension study. Treatment-emergent adverse events (TEAEs) were reported in 757/843 (89.8%) patients, the most common being nasopharyngitis (39.7%) and herpes zoster (11.7%). The majority of TEAEs were severity grade 1/2. Drug-related TEAEs leading to permanent study drug discontinuation occurred in 55/843 (6.5%) patients. Regarding AEs of special interest, the incidence per 100 patient-years of serious infections was 2.3 (95% CI 1.6 - 3.1), herpes zoster-related disease 6.8 (95% CI, 5.6 - 8.3), and malignancies 1.1 (95% CI, 0.7 - 1.8). One death from diffuse large B cell lymphoma during the study and one death from uterine sarcoma after the study were considered probably and possibly related to study drug, respectively. CONCLUSIONS: The effectiveness of peficitinib was maintained or improved during long-term administration and treatment up to 6 years was well tolerated in Asian patients with RA. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01638013, registered retrospectively 11 July 2012.

Switching from tenofovir disoproxil fumarate to tenofovir alafenamide in virologically suppressed patients with chronic hepatitis B: a randomised, double-blind, phase 3, multicentre non-inferiority study.

BACKGROUND: Treatment with tenofovir disoproxil fumarate has been associated with renal toxicity or reductions in bone mineral density, or both, in some patients with chronic hepatitis B virus (HBV) infection. Tenofovir alafenamide is a tenofovir prodrug with high intrahepatic concentrations of active drug and reduced systemic tenofovir exposures compared with tenofovir disoproxil fumarate. In patients with chronic HBV, tenofovir alafenamide has shown efficacy non-inferior to that of tenofovir disoproxil fumarate with improved renal and bone safety. With this non-inferiority study, we aimed to evaluate the efficacy and safety of tenofovir alafenamide in patients with HBV infection switching from tenofovir disoproxil fumarate who are virally suppressed. METHODS: Patients with chronic HBV infection who had been receiving tenofovir disoproxil fumarate for 48 weeks or more and who had HBV DNA less than the lower limit of quantification (LLOQ) for at least 12 weeks were recruited to this randomised, multicentre, double-blind, phase 3 non-inferiority study. Patients were randomly assigned in a 1:1 ratio to receive tenofovir alafenamide 25 mg once a day or to continue tenofovir disoproxil fumarate 300 mg once a day. The primary efficacy endpoint was loss of virological control, defined as the proportion of patients who received at least one dose of study drug who had HBV DNA of at least 20 IU/mL at week 48 by the modified US Food and Drug Administration (FDA) snapshot algorithm. Key safety endpoints were changes in hip and spine bone mineral density, estimated creatinine clearance by Cockcroft-Gault, and markers of bone turnover and renal tubular function. The study was powered for non-inferiority in efficacy of tenofovir alafenamide versus tenofovir disoproxil fumarate with a 4% margin. Investigators and patients were unaware of treatment allocation and on-treatment results. This trial is ongoing and is registered with ClinicalTrials.gov, number NCT02979613. FINDINGS: Participants in this study were enrolled between Dec 29, 2016, and Oct 20, 2017. 541 patients were screened and 490 patients were randomly assigned to switch to tenofovir alafenamide or to stay on tenofovir disoproxil fumarate. Two patients assigned to receive tenofovir alafenamide did not receive treatment; thus the full analysis set for efficacy and safety analyses consisted of 243 patients in the tenofovir alafenamide group and 245 in the tenofovir disoproxil fumarate group. At week 48, one patient from each treatment group (both <1%) had HBV DNA of at least 20 IU/mL (difference in proportion 0·0%, 95% CI -1·9 to 2·0), thereby showing non-inferior efficacy of tenofovir alafenamide to tenofovir disoproxil fumarate. Patients who received tenofovir alafenamide had significantly increased bone mineral density at hip (mean change 0·66% [SD 2·08] vs -0·51% [SD 1·91]; difference in least square means 1·17% [95% CI 0·80 to 1·54; p<0·0001]) and at spine (mean change 1·74% [3·46] vs -0·11% [3·13]; difference in least square means 1·85% [1·24 to 2·46; p<0·0001]), creatinine clearance by Cockcroft-Gault relative to tenofovir disoproxil fumarate (median change 0·94 mL/min [IQR -4·47 to 6·24] vs -2·74 mL/min [-7·89 to 1·88]; p <0·0001), and improved markers of bone turnover and tubular function at week 48. The most common treatment-emergent adverse events were upper respiratory tract infection (18 [7%] of 243 patients in the tenofovir alafenamide group and 16 [7%] of 245 patients in the tenofovir disoproxil fumarate group) and nasopharyngitis (13 [5%] of 243 patients in the tenofovir alafenamide group and 12 [5%] of 245 patients in the tenofovir disoproxil fumarate group). The incidence of grade 3 and above adverse events and serious adverse events was low and similar between groups. No viral resistance was observed in patients who qualified for viral sequencing. INTERPRETATION: These findings suggest that tenofovir alafenamide can be substituted for tenofovir disoproxil fumarate in patients with HBV infection for improved safety without a loss of efficacy.

Serlopitant for psoriatic pruritus: A phase 2 randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Pruritus, a common symptom of psoriasis, negatively affects quality of life; however, treatment of lesional skin does not consistently alleviate psoriatic itch. OBJECTIVE: To examine the effects of serlopitant, an oral, once-daily neurokinin 1 receptor antagonist, for treatment of psoriatic pruritus in a phase 2, randomized clinical trial (NCT03343639). METHODS: Patients (n = 204) were randomized to receive serlopitant, 5 mg, or placebo daily for 8 weeks. Eligible adult patients had plaque psoriasis for ≥6 months, plaques covering ≤10% of body surface area, pruritus for ≥4 weeks, and Worst Itch Numeric Rating Scale (WI-NRS) score ≥7 at the initial screening. RESULTS: Participants (54.2% women) had a mean age of 47.5 years and 85.2% were white. Mean baseline WI-NRS scores were 8.3 for serlopitant and 8.1 for placebo. The WI-NRS 4-point response rate at 8 weeks (primary end point) was 33.3% for serlopitant vs 21.1% for placebo (P = .028); at 4 weeks the rates were 20.8% for serlopitant vs 11.5% for placebo (P = .039). Treatment-related adverse events were reported for 4.9% of serlopitant-treated and 4.0% of placebo-treated patients. LIMITATIONS: This was a phase 2 study with a small study population. Patients with severe psoriasis were excluded. CONCLUSION: Serlopitant significantly reduced pruritus associated with mild to moderate psoriasis, supporting continued development of serlopitant for this patient population.
