ABSTRACT: Objective
To evaluate the efficacy and safety of pegylated interferon alpha-2b (PEG IFN-α2b) administered in conjunction with the standard of care (SOC) in subjects with moderate coronavirus disease-19 (COVID-19).Methods
In this study, adult subjects with confirmed moderate COVID-19 were randomized in a 1:1 ratio to receive either PEG IFN-α2b + SOC or SOC alone. The primary endpoint was a two-point improvement in clinical status on Day 11, measured by the World Health Organization's seven-point ordinal scale.Results
Of 250 subjects, 120 were randomized to the PEG IFN-α2b + SOC arm and 130 were randomized to the SOC arm. The results for the PEG IFN + SOC arms vs the SOC arm for the proportion of subjects with a two-point improvement in the seven-point ordinal scale were 80.36% vs 68.18% (P=0.037) on Day 8, 91.60% vs 92.56% (P=0.781) on Day 11, and 94.12% vs 95.93% (P=0.515) on Day 15. There was a time-dependent decrease in the biomarkers in both arms, and no clinically significant changes in laboratory parameters. The safety profile was similar in both arms.Conclusion
PEG IFN-α2b induced early viral clearance, improved the clinical status, and decreased the duration of supplemental oxygen. It provides a viable treatment option and can limit the spread of severe acute respiratory syndrome coronavirus-2.

Project description:ObjectiveTo evaluate the efficacy and safety of pegylated interferon alfa-2b (PEG IFN-α2b) along with the standard of care (SOC) in subjects with moderate COVID-19.MethodsIn this phase 2, randomized, open-label study, adult subjects aged ≥18 years with RT-PCR confirmed COVID-19 with moderate symptoms were randomized in a 1:1 to receive PEG IFN-α2b plus SOC, or SOC alone. The primary endpoint was improvement in clinical status on day 15, measured by the WHO 7-point ordinal scale.ResultsForty subjects were randomized to PEG IFN-α2b plus SOC (n = 20) and SOC (n = 20). Overall, 19 (95.00%) subjects in PEG IFN-α2b plus SOC had achieved clinical improvement on day 15 compared to 13 (68.42%) subjects in SOC (p < 0.05). Overall, 80% and 95% of subjects in the PEG IFN-α2b plus SOC group had a negative RT-PCR result on day 7 and day 14, respectively, compared to 63% and 68% in the SOC group. Adverse events (AEs) were reported for eleven subjects in the PEG IFN-α2b plus SOC group and eight subjects in the SOC group. All reported AEs were mild.ConclusionThe significant improvement in clinical status on day 15 is likely due to faster viral reduction compared to SOC with the PEG IFN-α2b treated moderate COVID-19 subjects showing a difference as early as day seven and becoming significant by day 14.

Project description:BackgroundUntil now, various types of combined therapy with nucleotide analogs and pegylated interferon (Peg-INF) in patients with hepatitis B patients have been tried. However, studies regarding the benefits of de novo combination, late-add on, and sequential treatment are very limited. The objective of the current study was to identify the efficacy of sequential treatment of Peg-INF after short-term antiviral treatment.MethodsBetween June 2010 and June 2015, hepatitis B e antigen (HBeAg)-positive patients (n = 162) received Peg-IFN for 48 weeks (mono-treatment group, n = 81) and entecavir (ETV) for 12 weeks with a 48-week course of Peg-IFN starting at week 5 of ETV therapy (sequential treatment group, n = 81). The primary endpoint was HBeAg seroconversion at the end of follow-up period after the 24-week treatment. The primary endpoint was analyzed using Chi-square test, Fisher's exact test, and regression analysis.ResultsHBeAg seroconversion rate (18.2% vs. 18.2%, t = 0.03, P = 1.000) and seroclearance rate (19.7% vs. 19.7%, t = 0.03, P = 1.000) were same in both mono-treatment and sequential treatment groups. The rate of alanine aminotransferase (ALT) normalization (45.5% vs. 54.5%, t = 1.12, P = 0.296) and serum hepatitis B virus (HBV)-DNA <2000 U/L (28.8% vs. 28.8%, t = 0.10, P = 1.000) was not different in sequential and mono-treatment groups at 24 weeks of Peg-INF. Viral response rate (HBeAg seroconversion and serum HBV-DNA <2000 U/L) was not different in the two groups (12.1% vs. 16.7%, t = 1.83, P = 0.457). Baseline HBV-DNA level (7 log10U/ml vs. 7.5 log10U/ml, t = 1.70, P = 0.019) and hepatitis B surface antigen titer (3.6 log10U/ml vs. 4.0 log10U/ml, t = 2.19, P = 0.020) were lower and predictors of responder in mono-treatment and sequential treatment groups, respectively.ConclusionsThe current study shows no differences in HBeAg seroconversion rate, ALT normalization, and HBV-DNA levels between mono-therapy and sequential therapy regimens.Trial registrationClinicalTrials.gov, NCT01220596; https://clinicaltrials.gov/ct2/show/NCT01220596?term=NCT01220596&rank=1.

Project description:IntroductionAtopic dermatitis (AD) is a chronic inflammatory skin disorder with limited treatment options for adolescents with moderate-to-severe disease. Lebrikizumab, a monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in previous Phase 3 trials: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), and ADhere (NCT04250337). We report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open-label study of lebrikizumab in adolescent patients with moderate-to-severe AD. The primary endpoint was to describe the proportion of patients who discontinued from study treatment because of adverse events (AEs) through the last treatment visit.MethodsAdolescent patients (N = 206) (≥ 12 to < 18 years old, weighing ≥ 40 kg) with moderate-to-severe AD received subcutaneous lebrikizumab 500 mg loading doses at baseline and Week 2, followed by 250 mg every 2 weeks (Q2W) thereafter. Safety was monitored using reported AEs, AEs leading to treatment discontinuation, vital signs, growth assessments, and laboratory testing. Efficacy analyses included Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Body Surface Area (BSA), (Children's) Dermatology Life Quality Index ((C)DLQI), and Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression.Results172 patients completed the treatment period. Low frequencies of SAEs (n = 5, 2.4%) and AEs leading to treatment discontinuation (n = 5, 2.4%) were reported. Overall, 134 patients (65%) reported at least one treatment-emergent AE (TEAE), most being mild or moderate in severity. In total, 62.6% achieved IGA (0,1) with ≥ 2-point improvement from baseline and 81.9% achieved EASI-75 by Week 52. The EASI mean percentage improvement from baseline to Week 52 was 86.0%. Mean BSA at baseline was 45.4%, decreasing to 8.4% by Week 52. Improvements in mean change from baseline (CFB) to Week 52 were observed in DLQI (baseline 12.3; CFB - 8.9), CDLQI (baseline 10.1; CFB - 6.5), PROMIS Anxiety (baseline 51.5; CFB - 6.3), and PROMIS Depression (baseline 49.3; CFB - 3.4) scores.ConclusionsLebrikizumab 250 mg Q2W had a safety profile consistent with previous trials and significantly improved AD symptoms and quality of life, with meaningful responses at Week 16 increasing by Week 52.Trial registrationClinicalTrials.gov identifier, NCT04250350.

Project description:IntroductionAlthough many biologic therapies are effective for clearing skin of patients with psoriasis, some lose effectiveness over time. This phase 2 open-label extension (OLE) trial was designed to investigate the long-term safety and efficacy of risankizumab.MethodsIn the phase 2, double-blind, active comparator, predecessor trial (NCT02054481), patients with moderate-to-severe chronic plaque psoriasis were treated for 24 weeks with subcutaneous (SC) risankizumab or ustekinumab, followed by a 24-week follow-up without treatment administration. Patients could enroll in the OLE (NCT02203851) when they experienced loss of treatment response (< 50% improvement in the Psoriasis Area Severity Index [PASI 50]) during follow-up) or at the end of follow-up if treatment response was ongoing. In the OLE, patients were treated every 12 weeks for at least 48 weeks with SC risankizumab 90 or 180 mg, beginning at week 12 (OLE visit 2), if the patient had not achieved PASI 90. Efficacy endpoints included the proportions of patients who achieved PASI 50/75/90/100 and static Physician's Global Assessment (sPGA) of clear or almost clear skin at week 48 (sPGA 0/1; OLE visit 5).ResultsOf the 110 enrolled patients, 99 (90.0%) completed the OLE. No patients discontinued the study because of adverse events. At week 48, 74.1% of patients achieved PASI 90, whereas 98.1, 91.7, 53.7, and 67.6% achieved PASI 50/75/100 and sPGA 0/1, respectively. All efficacy results were consistent or slightly increased at OLE week 48 compared with week 12. No new safety findings were observed.ConclusionRisankizumab treatment was well tolerated with sustained clinical efficacy for at least 48 weeks.Trial registrationClinicalTrials.gov identifier; NCT02203851.

Project description:Purpose: Studying the efficacy and safety of apremilast as an add-on therapy in patients with recalcitrant cutaneous dermatomyositis. Studying the mechanism of action of apremilast in dermatomyositis by performing RNA sequencing and immunohistochemistry on skin biopsies before and after treatment. Methods: We enrolled 8 patients with recalcitrant dermatomyositis. Apremilast 30 mg orally twice daily was added to a stable treatment regimen of steroids and/or steroids sparing agents and patients were followed for 7 months. A CDASI, muscle score, dermatology life quality index (DLQI), and depression assessments were performed at baseline and regularly till month 7. Skin biopsies were performed at baseline and 3-months post-apremilast to study gene expression alterations. Results: Our ORR assessed at 3 months post apremilast was 87.5%. The response was maintained at 6 months with continued decrease in CDASI and improvement in DLQI. The mean decrease in CDASI was 12.9 points (p<0.05). Apremilast was well tolerated and without any grade 3 or higher adverse events using CTCAE version 5. RNA sequencing was performed on skin biopsies from 7 patients before and 3 months after apremilast. Out of 39,076 expressed genes, there were 195 whose expression changed ≥2-fold at P<0.01 (123 down- and 72 up-regulated), several genes are known JAK-STAT targets. Using GSEA analysis, we identified 13 pathways significantly downregulated by apremilast, notably STAT1, STAT3, IL-2, IL-6, IL-12, IL-23, INFγ, and TNFα pathways. Immunohistochemical staining confirmed JAK/STAT signaling inhibition at the protein level. Conclusions: Apremilast is a safe and efficacious add-on treatment in recalcitrant dermatomyositis with an overall response rate of 87.5%, and functions through downregulation of JAK/STAT signaling in dermatomyositis.

Project description:A previous dose-finding study has suggested that romiplostim is effective in patients with refractory aplastic anaemia (AA) and 10 µg/kg once weekly was recommended as a starting dose. In this Phase II/III, multicentre, open-label study, romiplostim was administered subcutaneously at a fixed dose of 10 µg/kg once weekly for 4 weeks (weeks 1-4) followed by weekly doses (5, 10, 15 and 20 µg/kg) titrated by platelet response for up to 52 weeks (weeks 5-52). A total of 31 patients with AA who were refractory to immunosuppressive therapy (IST) and thrombocytopenia (platelet count of ≤30 × 109 /l) were enrolled. The primary efficacy endpoint of the proportion of patients achieving any haematological (platelet, neutrophil and erythrocyte) response at week 27 was 84% [95% confidence interval (CI) 66-95%]. Trilineage response was 39% (95% CI 22-58%) at week 53. The most common treatment-related adverse events (AEs) were headache and muscle spasms (each 13%). All AEs were mild or moderate except for three patients with Grade 3 hepatic AEs; no AEs necessitated romiplostim discontinuation. Two patients developed cytogenetic abnormalities, of whom one returned to normal karyotype at last follow-up. High-dose romiplostim is effective and well tolerated in the treatment of patients with AA refractory to IST.

Project description:IntroductionAlthough dimethyl fumarate (DMF) has been approved since 2017 for treatment of moderate-to-severe plaque psoriasis, limited data on its safety and efficacy are available in clinical practice. The objective was to assess the efficacy and safety of DMF in patients with moderate-to-severe plaque psoriasis through 52 weeks in conditions close to real clinical practice.MethodsDIMESKIN 1 was a 52-week, open-label, phase IV clinical trial conducted at 36 Spanish sites. Adults with diagnosis of moderate-to-severe plaque psoriasis, treated with DMF as per its summary of product characteristics and with ≥ 1 post-baseline Psoriasis Area and Severity Index (PASI) value were included [intention-to-treat (ITT) population]. Efficacy analyses were performed for ITT population and are based on multiple imputation.ResultsOverall, 282 and 274 patients were included in the safety and ITT populations, respectively. At week 24, 46.0%/24.8%/10.9% of patients achieved PASI 75/90/100 response, respectively. At week 52, these percentages were 46.0%/21.9%/10.9%, respectively. Mean body surface area affected decreased from 17.4% to 6.9%/7.3% after 24/52 weeks (p < 0.001, both). A total of 42.9%/49.4% of patients had a Physician's Global Assessment 0-1 at week 24/52, respectively. Mean pruritus visual analogue scale (VAS) significantly decreased after 24 and 52 weeks (p < 0.001, both), with 56.5% and 67.6% of patients, respectively, rating a pruritus VAS < 3. At week 24/52, 61.3%/73.4% patients had a Dermatology Life Quality Index (DLQI) ≤ 5 and 34.7%/32.1% had a DLQI 0-1. The most frequent adverse events were gastrointestinal disorders (mainly diarrhea/abdominal pain in 50.0%/35.1% of patients, respectively), flushing (28.0%), and lymphopenia (31.2%), mostly mild/moderate.ConclusionsDMF significantly improves main severity and extension indexes and rates, as well as patient-reported outcomes such as pruritus and quality of life in patients with moderate-to-severe psoriasis after 24 weeks of treatment. These improvements are sustained through 52 weeks. The safety profile of DMF is similar to that previously described for fumarates.Eudract number2017-00136840.

Project description:BackgroundA ready-to-use liquid formulation of abobotulinumtoxinA (aboBoNT-A solution) has been developed.ObjectivesThe aim of this study was to assess the long-term efficacy and safety of aboBoNT-A solution for the treatment of glabellar lines.MethodsThis was a multicenter, multinational, Phase III study (NCT02493946), with randomized double-blind placebo-controlled (DBPC; 2:1 aboBoNT-A solution 50 U/placebo) and open-label (4 cycles aboBoNT-A solution) periods; additional patients were recruited into the open-label period. Patients were 18 to 65 years old, BoNT-naïve, and dissatisfied/very dissatisfied with moderate/severe glabellar lines at maximum frown. Investigator's live assessment (primary endpoint)/subject's self-assessment of glabellar line severity at maximum frown, patient satisfaction with glabellar line appearance, and FACE-Q patient-reported scales (facial appearance overall, psychological well-being, aging) were assessed. Adverse events were monitored. Analyses were performed on DBPC and long-term analysis (LTA; all patients receiving ≥1 aboBoNT-A solution injection) populations.ResultsResponder rates for the investigator's live assessment, the subject's self-assessment, and patient satisfaction were consistent at Day 29 postinjection across repeat LTA cycles (82.2%-87.8%, 62.8%-80.6%, and 72.2%-87.8%, respectively), with statistically significantly higher responder rates vs placebo (DBPC cycle: 81.6% vs 0.8%, 68.1% vs 2.3%, and 83.1% vs 5.7%, respectively; all P < 0.0001). Consistent improvements on FACE-Q scales occurred with repeat cycles (DBPC cycle: aboBoNT-A solution vs placebo, P < 0.0001). No new or unexpected adverse events, or neutralizing antibodies, were observed.ConclusionsThese results support the long-term efficacy and safety of aboBoNT-A solution, and its superiority over placebo, for treatment of glabellar lines in adults.Level of evidence: 1

Project description:BackgroundDual bronchodilation combining a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) is the preferred choice of treatment recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guidelines for the management of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). The once-daily (q.d.) fixed-dose combination (FDC) of LABA, indacaterol 110 μg and LAMA, glycopyrronium 50 μg (IND/GLY 110/50 μg q.d.) demonstrated superior improvements in lung function, dyspnoea and overall health status and better tolerability against LABA or LAMA monotherapies and combination of LABA and inhaled corticosteroid (ICS) in more than 11,000 patients with moderate-to-severe COPD in several randomised controlled clinical trials.MethodsThe CRYSTAL study was the first, 12-week, randomised, open-label trial that evaluated the efficacy and safety of a direct switch from previous treatments to IND/GLY 110/50 μg q.d. on lung function and dyspnoea in patients with moderate COPD and a history of up to one exacerbation in the previous year. Patients were divided into 2 groups according to their background therapy and symptom scores and were randomised (3:1) to IND/GLY or to continue with their previous treatments.ResultsThe study included 4389 randomised patients, of whom 2160 were in groups switched to IND/GLY (intention-to-treat population). The effect of IND/GLY was superior to LABA + ICS on trough forced expiratory volume in 1 s (FEV1; treatment difference, Δ = +71 mL) and transition dyspnoea index (TDI; [Δ = 1.09 units]), and to LABA or LAMA on trough FEV1 (Δ = +101 mL) and a TDI (Δ = 1.26 units). Improvements in health status and lower rescue medication use were also observed with IND/GLY. The safety profile of the study medication was similar to that observed in previous studies.ConclusionsIND/GLY demonstrated superior improvements in lung function and dyspnoea after direct switch from previous treatments.Trial registrationClinicalTrials.gov number: NCT01985334 .

Project description:IntroductionPeficitinib is a novel orally bioavailable, once-daily Janus kinase (JAK) inhibitor approved in Japan for the treatment of rheumatoid arthritis (RA). This 2-year extension study of two global phase IIb trials investigated the long-term safety and effectiveness of peficitinib.MethodsAll eligible patients with moderate-to-severe RA including patients in the placebo group who participated in one of two global phase IIb trials ('with methotrexate' or 'without methotrexate') were included in this 2-year open-label extension study and were converted to peficitinib 100 mg once daily. The primary objective was to evaluate an additional 2 years of safety by assessing treatment-emergent adverse events (AEs) and clinical laboratory evaluations for 105 weeks. Evaluation of an additional 2 years of effectiveness using American College of Rheumatology (ACR) 20/50/70 responses was the exploratory objective.ResultsOverall, 611 patients were enrolled in the extension study: 319 (52.2%) patients completed the study and 292 (48%) discontinued treatment, including for withdrawal of patient consent (n = 96), failure to achieve low disease activity (n = 62), and AE not including death (n = 41). AEs were reported in 463 (76%) patients. The most common AEs (per 100 patient-years) were upper respiratory tract infections (9.9) and urinary tract infections (7.2). Serious AEs were reported in 80 (13%) patients, with incidences per 100 patient-years of serious infections 2.7, herpes zoster 1.5 (including one herpes zoster ophthalmic), and malignancies 0.6 (most frequently basal cell carcinoma). At week 105, 269 (44%) patients demonstrated an ACR20 response relative to their respective phase IIb trial baselines.ConclusionAmong 319 patients who completed this 2-year extension of two global phase IIb studies, peficitinib 100 mg once daily demonstrated a stable safety profile and sustained effectiveness in patients with moderate-to-severe RA.Trial registrationClinicalTrials.gov identifier, NCT01711814.
