Project description:ObjectiveThis phase I study aimed to systematically assess the safety, local tolerability, pharmacokinetics, and preliminary efficacy of topical icotinib hydrochloride cream in patients with mild to moderate plaque psoriasis.Materials and methodsEligible Chinese adult patients with mild to moderate psoriasis were assigned to the icotinib cream or vehicle group. Icotinib cream with increasing concentrations (0.5%, 1.0%, 2.0%, and 4.0%) or vehicle were administered by the fingertip unit method to the skin lesions twice a day for 4 weeks. Safety assessments included the incidence and severity of adverse events (AEs), local tolerability at the treatment area, vital signs, and laboratory examinations. Plasma levels of icotinib were also measured for the pharmacokinetics calculation. The efficacy was preliminarily explored by assessing the improvement in the severity level using Target Plaque Severity Score (TPSS) and overall improvement using the Psoriasis Area Severity Index (PASI) and Dermatological Quality Life Index.ResultsForty-one patients were enrolled and qualified for safety analysis. 27 (65.9%) patients experienced at least one AE, of which application-site adverse drug reactions (ADRs) were reported in 6 (14.6%) patients. All ADRs were of grade 1 or 2, most common irritation (4.5%), itching (3.1%), and erythema (2.4%), and resolved during follow-up. The systemic exposure to icotinib was very low; the highest plasma concentration was 0.214 ng/mL, while the area under the curve from 0 to 12 hours was 1.626 h·ng/mL. The TPSS improved for all icotinib groups after treatment in a dose- and time-dependent manner.ConclusionThis phase 1 study demonstrated favorable safety, tolerable toxicity, and preliminary efficacy of icotinib cream in patients with mild to moderate psoriasis. The dose concentration of 2.0% (twice daily based on the fingertip unit method) is recommended for further study.Study designThis is a single-center, randomized, double-blind, and vehicle-controlled study.

Project description:BACKGROUND:Plaque psoriasis affects children and adults, but treatment options for paediatric psoriasis are limited. OBJECTIVES:To evaluate the efficacy and safety of ixekizumab (IXE), a high-affinity monoclonal antibody that selectively targets interleukin-17A, for moderate-to-severe paediatric psoriasis. METHODS:In a randomized, double-blind, placebo-controlled, phase III study (IXORA-PEDS), patients aged 6 to < 18 years with moderate-to-severe plaque psoriasis were randomized 2 : 1 to weight-based dosing of IXE every 4 weeks (IXE Q4W, n = 115) or placebo (n = 56) through week 12, followed by open-label IXE Q4W. Coprimary endpoints were the proportions of patients at week 12 achieving ? 75% improvement in Psoriasis Area and Severity Index (PASI 75) and those achieving a static Physician's Global Assessment score of 0 or 1 (sPGA 0,1). RESULTS:IXE was superior (P < 0·001) to placebo for both coprimary endpoints of PASI 75 (IXE Q4W, 89%; placebo, 25%) and sPGA (0,1) (IXE Q4W, 81%; placebo, 11%). IXE was also superior for all gated secondary endpoints, including PASI 75 and sPGA (0,1) at week 4, improvement in itch, and complete skin clearance. IXE Q4W provided significant (P < 0·001) improvements vs. placebo in quality of life and clearance of scalp and genital psoriasis. Responses at week 12 were sustained or further improved through week 48. Through week 12, 45% (placebo) and 56% (IXE) of patients reported treatment-emergent adverse events. One serious adverse event was reported (IXE), one patient discontinued due to an adverse event (placebo) and no deaths were reported. CONCLUSIONS:IXE was superior to placebo in the treatment of moderate-to-severe paediatric psoriasis, and the safety profile was generally consistent with that observed in adults. What is already known about this topic? Paediatric psoriasis affects approximately 1% of children and can negatively impact health-related quality of life. Treatment options for paediatric psoriasis are typically limited to off-label treatments and approved systemic biologics. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for moderate-to-severe plaque psoriasis in adults and was recently approved by the US Food and Drug Administration for moderate-to-severe paediatric psoriasis. What does this study add? Ixekizumab resulted in rapid and statistically significant improvements over placebo in skin involvement, itch and health-related quality of life, which persisted through 48 weeks of treatment in paediatric patients with moderate-to-severe plaque psoriasis. The safety profile of ixekizumab was generally consistent with that seen in adults. Ixekizumab may be an additional potential therapeutic option and an additional class of biologic therapy (interleukin-17A antagonist) for the treatment of moderate-to-severe paediatric psoriasis.

Project description:Psoriasis, a chronic inflammatory skin disease, negatively impacts patients' quality of life (QoL). This randomized, phase III, double-blind, placebo-controlled, multicenter study evaluated the efficacy and safety of brodalumab, a human anti-interleukin-17 receptor A monoclonal antibody, in Korean patients with moderate to severe plaque psoriasis. Coprimary end-points were the percentage of patients with 75% or more improvement in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment (sPGA) success (score 0/1) at week 12. Secondary end-points included the percentage improvement from baseline in PASI score and proportion of patients with PASI 50/75/90/100 responses. QoL was assessed with the Dermatology Life Quality Index (DLQI). Eligible patients were randomized to receive brodalumab 210 mg (N = 40) or placebo (N = 22) every 2 weeks (Q2W) at a 2:1 ratio for 12 weeks. Subsequently, all patients entered an open-label extension phase and received brodalumab 210 mg Q2W until week 62. At week 12, the proportion of patients who achieved the coprimary end-points, PASI 75 and sPGA success, was significantly higher in the brodalumab 210 mg Q2W group compared with the placebo group (92.5% vs 0%). At week 12, the mean ± SD percentage improvement in the PASI score was 96.87 ± 6.01% in the brodalumab 210 mg Q2W group, which was maintained until study end (week 64). PASI 50/75/90 responses were achieved by 100% of patients receiving brodalumab 210 mg Q2W at weeks 6, 13, and 24, respectively; PASI 100 was achieved by 82.8% of patients at week 64. Brodalumab treatment rapidly improved DLQI scores. The most common treatment-emergent adverse events were nasopharyngitis, upper respiratory tract infections, tinea pedis, and urticaria. Overall, treatment with brodalumab 210 mg Q2W resulted in a rapid and significant clinical benefit and was well tolerated in patients with moderate to severe plaque psoriasis in Korea.

Project description:ObjectivePsoriasis is an immune-mediated inflammatory skin disease. It can involve any body skin area, particularly the scalp, lower back, elbows, and knees. There are several topical and systemic therapies for the treatment. Nowadays, herbal medicines are popular treatments for dermatologic conditions. This two-arm parallel, randomized placebo-controlled clinical trial was conducted to examine the hypothesis of the efficacy of Melissa officinalis syrup on patients with mild-to-moderate Plaque psoriasis.ResultAmong 100 patients, 95 participants completed the trial and five of them withdrew. The mean pruritus intensity and PASI scores decreased significantly in the intervention group compared to the placebo group (P < 0.001). The DLQI score in the intervention group increased post-treatment compared to pre-treatment (P = 0.029); however, there was no significant difference between the intervention and control group at the end of the study (0.065).Trial registrationThe trial was registered in the Iranian registry of clinical trials on November 9th, 2019 ( https://www.irct.ir/trial/43434 ; registration number: IRCT20191104045326N1).

Project description:BackgroundEtanercept plus methotrexate combination therapy has not been adequately investigated in psoriasis.ObjectivesTo evaluate etanercept plus methotrexate vs. etanercept monotherapy in patients with moderate to severe plaque psoriasis who had not failed prior methotrexate or tumour necrosis factor-inhibitor therapy.MethodsPatients received etanercept 50 mg twice weekly for 12 weeks followed by 50 mg once weekly for 12 weeks and were randomized 1 : 1 to receive methotrexate (7·5-15 mg weekly) or placebo. The primary endpoint was the proportion of patients achieving ≥75% improvement in Psoriasis Area and Severity Index (PASI 75) at week 24.ResultsIn total, 239 patients were enrolled in each arm. PASI 75 was significantly higher at week 24 for the combination therapy group compared with the monotherapy group (77·3% vs. 60·3%; P < 0·0001). Other PASI improvement scores at week 12 [PASI 75, 70·2% vs. 54·3% (P = 0·01); PASI 50, 92·4% vs. 83·8% (P = 0·01); and PASI 90, 34·0% vs. 23·1% (P = 0·03)] showed similar results as did week 24 PASI 50 (91·6% vs. 84·6%; P = 0·01) and PASI 90 (53·8% vs. 34·2%; P = 0·01). Significantly more patients receiving combination therapy than monotherapy had static Physician's Global Assessment of clear/almost clear at week 12 (65·5% vs. 47·0%; P = 0·01) and week 24 (71·8% vs. 54·3%; P = 0·01). Adverse events (AEs) were reported in 74·9% and 59·8% of combination therapy and monotherapy groups, respectively; three serious AEs were reported in each arm.ConclusionsCombination therapy with etanercept plus methotrexate had acceptable tolerability and increased efficacy compared with etanercept monotherapy in patients with moderate to severe psoriasis.

Project description:IntroductionAdalimumab has been used successfully in the treatment of psoriasis. The objective of the study is to compare the efficacy, safety, and immunogenicity between HLX03, an adalimumab biosimilar, and adalimumab in Chinese patients with moderate-to-severe plaque psoriasis.MethodsIn this double-blind, active-controlled, parallel-group study, 262 patients with moderate-to-severe plaque psoriasis were randomized (1:1) to receive HLX03 or adalimumab (80 mg at week 1, 40 mg at week 2, and then 40 mg every 2 weeks) for 48 weeks. The primary endpoint was improvement in Psoriasis Area and Severity Index (PASI) score at week 16 comparing to baseline. Equivalence was demonstrated if 95% confidence interval (CI) of the between group difference fell within the equivalence margins of ± 15%. Other efficacy endpoints, safety and immunogenicity were also evaluated.ResultsIn the full analysis set, PASI improvements at week 16 was 83.5% (n = 131) in the HLX03 group and 82.0% (n = 130) in the adalimumab group, with a least-square-mean difference of 1.5% (95% CI - 3.9% to 6.8%). There were no significant between-group differences in all secondary efficacy analyses including proportion of patients achieving ≥ 75% improvement from baseline PASI (PASI 75), physician global assessment (PGA) 0/1 (clear or almost clear) and change in dermatology life quality index (DLQI) score. The incidences of adverse events and the proportion of patients with antidrug antibodies were also comparable between the two treatment groups.ConclusionHLX03 demonstrated equivalent efficacy, similar safety and immunogenicity to reference adalimumab, supporting its development as an alternative treatment for patients with plaque psoriasis in China.Clinical trial registrationChinadrugtrials.org.cn, CTR20171123 (November 27, 2017); ClinicalTrials.gov, NCT03316781 (October 20, 2017).

Project description:ObjectivesTo determine whether hydroxychloroquine decreases the risk of adverse outcome in patients with mild to moderate coronavirus disease 2019 (COVID-19) at high risk of worsening.MethodsWe conducted a multicentre randomized double-blind placebo-controlled trial evaluating hydroxychloroquine in COVID-19 patients with at least one of the following risk factors for worsening: need for supplemental oxygen, age ≥75 years, age between 60 and 74 years and presence of at least one co-morbidity. Severely ill patients requiring oxygen therapy >3 L/min or intensive care were excluded. Eligible patients were randomized in a 1:1 ratio to receive either 800 mg hydroxychloroquine on day 0 followed by 400 mg per day for 8 days or a placebo. The primary end point was a composite of death or start of invasive mechanical ventilation within 14 days following randomization. Secondary end points included mortality and clinical evolution at days 14 and 28, and viral shedding at days 5 and 10.ResultsThe trial was stopped after 250 patients were included because of a slowing down of the pandemic in France. The intention-to-treat population comprised 123 and 124 patients in the placebo and hydroxychloroquine groups, respectively. The median age was 77 years (interquartile range 58-86 years) and 151/250 (60.4%) patients required oxygen therapy. The primary end point occurred in 9/124 (7.3%) patients in the hydroxychloroquine group and 8/123 (6.5%) patients in the placebo group (relative risk 1.12; 95% CI 0.45-2.80). The rates of positive SARS-CoV-2 RT-PCR tests at days 5 and 10 were 72.8% (75/103) and 57.1% (52/91) in the hydroxychloroquine group, versus 73.0% (73/100) and 56.6% (47/83) in the placebo group, respectively. No difference was observed between the two groups in any of the other secondary end points.ConclusionIn this underpowered trial involving mainly older patients with mild to moderate COVID-19, patients treated with hydroxychloroquine did not experience better clinical or virological outcomes than those receiving the placebo.Trial registrationClinicalTrials.gov Identifier: NCT04325893 (https://clinicaltrials.gov/ct2/show/NCT04325893).

Project description:This phase 3 trial is the first to evaluate the efficacy and safety of treatment with the systemic TNF-? inhibitor, adalimumab, for Chinese patients with moderate-to-severe plaque psoriasis.In the 12-week, double-blind, placebo-controlled Period A, patients were randomized 4 : 1 to receive adalimumab 40 mg every-other-week (following a single 80 mg dose), or placebo every-other-week. In the subsequent 12-week, open-label, Period B, all patients received adalimumab 40 mg every-other-week starting at week 13, following a single, blinded dose at week 12 of adalimumab 80 mg or matching placebo (for patients receiving placebo or adalimumab in Period A respectively). In Period A, efficacy was analysed for all randomized patients and safety for all patients receiving ?1 dose of the study drug.For the 425 patients in this study (87 placebo; 338 adalimumab), a higher percentage randomized to adalimumab achieved the primary endpoint of ?75% improvement from baseline in PASI score (PASI 75) at week 12: placebo 11.5% (10/87); adalimumab 77.8% (263/338; P < 0.001). Physician's Global Assessment of clear to minimal was achieved at week 12 by 14.9% placebo (13/87) and 80.5% adalimumab (272/338; P < 0.001). For patients who received adalimumab at any time during the study (All-adalimumab Population), treatment-emergent adverse events (AEs) were reported by 63.4%; the most common was upper respiratory infection (16.1%). Serious AEs were reported by 3.5% of the All-adalimumab Population, and serious infectious AEs by 1.2%, which include lung infection, pneumonia and tuberculosis [2 (0.5%) patients each]. There was one death (chronic heart failure).In these Chinese patients with moderate-to-severe psoriasis, a significantly greater percentage treated with adalimumab compared with placebo achieved efficacy endpoints at week 12 and efficacy was sustained to week 24. Safety results were consistent with the known adalimumab safety profile; no new safety signals were identified in the 24 weeks of treatment.

Project description:Background:Psoriasis is a common chronic inflammatory skin disease with high recurrence rates and increasing incidence. Patients require long-term medication to reduce symptoms and prevent disease progression. Therefore, the development of treatments with high efficiency and low rate of adverse events is of utmost importance. Traditional Chinese medicine (TCM) plays an outstanding role in reducing disease symptoms and improving quality of life. The aim of this trial is to clarify the treatment efficacy, safety, and control of disease recurrence in patients with psoriasis with blood-stasis syndrome treated with Taodan granules (TDKL). Methods:This trial is a five-center, randomized, double-blind, placebo-controlled study planned to transpire between September 1, 2019, and December 31, 2021. A sample size of 216 participants (108 per group) with mild-to-moderate psoriasis will be randomly assigned to receive TDKL or placebo twice per day, 7 days per week, for 8 weeks. The study duration will be 17 weeks, including a 1-week screening period, 8 weeks of intervention, and another 8 weeks of follow-up. The primary outcomes are improvement in the Psoriasis Area and Severity Index score and recurrence rate after 8 weeks of treatment. Secondary outcomes include body surface area affected and the scores for the Physician Global Assessment, Dermatology Life Quality Index, pain-related quality of life, pain on the visual analogue scale, and TCM syndromes. The number, nature, and severity of adverse events will be carefully recorded. Discussion:The study results will help clarify the safety and efficacy of TDKL as treatment for psoriasis with respect to both disease regression and recurrence rate. We expect that this study will provide high-quality evidence with important public health implications that may alter the approach to psoriasis management in China. Trial registration:The trial has been registered at ClinicalTrials.gov (ID: NCT03942198).

Project description:BackgroundMost patients with chronic plaque psoriasis receive topical treatment; however, available options lack a balance of efficacy with long-term safety and tolerability. Roflumilast cream 0.3% is a highly potent phosphodiesterase 4 (PDE4) inhibitor approved by the US FDA for treatment of psoriasis.ObjectiveThe aim of this study was to define the pharmacokinetic (PK) profile of roflumilast delivered topically from a phase I maximal usage study and data from phase II and phase III studies.MethodsPK data for roflumilast and the active metabolite, roflumilast N-oxide, were determined from a phase I PK and safety maximal usage study of roflumilast cream 0.3% applied once daily for 14 days in patients with plaque psoriasis affecting body surface area (BSA) ≥20% (N = 26). Serial plasma samples were obtained on Days 1 and 15 to determine maximum plasma concentration (Cmax) and area under the concentration-time curve (AUC). Plasma concentrations were also assessed at Weeks 3, 4, and 5 for terminal half-life (t½). Concentrations of roflumilast and roflumilast N-oxide in skin were assessed at Day 28 for 14 patients with psoriasis in a phase I/IIa study of once-daily roflumilast cream 0.5% and 0.15% for 28 days. Systemic exposure (Ctrough and AUC) of roflumilast and roflumilast N-oxide in two phase III trials (DERMIS-1, n = 245; DERMIS-2, n = 250) of roflumilast cream 0.3% for 8 weeks was assessed at Weeks 4 and 8.ResultsBioavailability of roflumilast cream 0.3% after topical administration was 1.5%. Unlike after oral dosing, the plasma concentration-time curve was flat, with a peak-to-trough ratio of 1.2. Roflumilast N-oxide concentrations were eightfold higher than roflumilast concentrations. The t½ in adult patients was 4.0 days for roflumilast and 4.6 days for roflumilast N-oxide following the last dose administered. Steady state was reached by Day 15. Concentrations of roflumilast in skin were, on average, 126- and 61.8-fold higher than corresponding mean plasma Ctrough following administration of roflumilast cream 0.15% and 0.5% daily for 28 days. Roflumilast N-oxide was quantifiable in only one skin sample (N = 27). Following 8 weeks of treatment in DERMIS-1, mean plasma Ctrough of roflumilast was 1.78 ng/mL, and 9.86 ng/mL for roflumilast N-oxide. In DERMIS-2, mean plasma Ctrough was 1.72 ng/mL and 10.2 ng/mL, respectively. In the maximal usage study (mean BSA: 27.5%), eight patients (30.8%) experienced adverse events (AEs) and all were mild or moderate, with no reports of diarrhea, headache, insomnia, or application-site pain; no patients discontinued treatment due to an AE.ConclusionTopical administration of roflumilast cream 0.3% results in concentrations in skin 126- and 61.8-fold higher relative to plasma, which are much higher than expected to be achievable with oral dosing. PDE4 inhibition in the skin is likely due to roflumilast as compared with its active metabolite, as there is no significant conversion to roflumilast N-oxide in the skin. Consistent with reservoir formation and retention of drug in the stratum corneum, roflumilast is slowly released from the skin (t½ 4 days) and peak-to-trough ratio is 1.2.ClinicaltrialsGov identifiersNCT04279119, NCT03392168, NCT04211363, NCT04211389.
