Safety and effectiveness of everolimus in maintenance kidney transplant patients in the real-world setting: results from a 2-year post-marketing surveillance study in Japan.

ABSTRACT:

Background

Data on real-world use of everolimus (EVR) in Japanese maintenance kidney transplant (KTx) patients are limited. This post-marketing surveillance study was conducted to assess the safety and effectiveness of EVR, and identify factors affecting renal impairment.

Methods

Adult maintenance KTx patients were enrolled within 14 days of initiating EVR. Patient medical data were collected using electronic data capture case report forms at 6 months, 1, and 2 years after initiating EVR, or at discontinuation.

Results

All patients receiving EVR in Japan during the surveillance period were enrolled (N = 263). Mean time from transplantation to EVR initiation was 75.7 months. Decreased renal function (31.56%) was the primary reason for initiating EVR. In combination with EVR, the mean daily dose of tacrolimus and cyclosporine could be reduced to ~ 79 and ~ 64%, by 2 years, respectively. Incidences of serious adverse events and adverse drug reactions were 15.97 and 49.43%, respectively. Two-year graft survival rate was 95.82% and low in patients with baseline estimated glomerular filtration rate (eGFR; modification of diet in renal disease) < 30 mL/min/1.73 m² (69.57%; P < 0.0001) and urinary protein/creatinine ratio (UPCR) ≥ 0.55 g/gCr (84.21%; P = 0.0206). Throughout the survey, mean eGFR values were stable (> 55 mL/min/1.73 m²). Renal impairment was influenced by patient and donor age, eGFR, and UPCR at baseline.

Conclusions

No new safety concerns for the use of EVR in adult maintenance KTx patients were identified. Early EVR initiation may be considered in these patients before renal function deterioration occurs.

Project description:Hidradenitis suppurativa (HS) is a painful chronic skin disease characterized by abscesses, nodules, and tunnels in the skin. Adalimumab, a monoclonal antibody against tumor necrosis factor-α, is approved for the treatment of HS in Europe, the USA, and Japan. This multicenter, open-label, post-marketing, observational study (ClinicalTrials.gov: NCT03894956) evaluated the safety and effectiveness of adalimumab in routine clinical practice in Japan (March 2019-May 2021). Patients with HS were treated with s.c. doses of adalimumab according to the dosage described in the package insert. The primary end-point was safety (data cut-off, December 2020). Secondary end-points assessed effectiveness, including HS Clinical Response (HiSCR), skin pain, Dermatology Life Quality Index (DLQI), and C-reactive protein (CRP). Here, we report 12-week interim effectiveness results. A total of 84 eligible patients from 65 sites were enrolled; 83 patients were included in this analysis. Mean age was 42.0 years, mean body mass index was 26.9 kg/m2 , 78.3% of patients were male, 61.4% had Hurley stage III disease, 39.8% had a disease duration ≥10 years, and 7.2% had a family history of HS. The most common affected sites were the axilla (60.2%), buttocks (59.0%), and the inguinal and femoral regions (47.0%). Mean abscess and inflammatory nodule count was 13.0 (standard deviation, 12.0). Among patients with a comorbidity (57.8%), the most common were diabetes mellitus, hypertension, and chronic kidney disease. No patient reported a serious infection or any safety event of special interest. One patient died from a serious adverse event of cardiac failure unrelated to adalimumab. At week 12, 57.4% of patients achieved HiSCR, and significant reductions from baseline in skin pain, DLQI (both p < 0.0001), and CRP (p = 0.0029) were observed. These results support the administration of adalimumab as a well-tolerated and effective treatment for Japanese patients with HS in real-world clinical practice.

Project description:IntroductionTeneligliptin is a dipeptidyl peptidase 4 inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. We performed a long-term post-marketing surveillance (RUBY) to obtain real-world evidence regarding the safety and efficacy of teneligliptin in Japan.MethodsThis 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs) and laboratory variables. Data were evaluated in all patients and in patients divided according to baseline renal function across categories of estimated glomerular filtration rate (G1-G5) and dialysis. Safety was assessed as the incidence of ADRs and efficacy was assessed in terms of glycaemic control, for up to 3 years.ResultsOf 11,677 patients registered, 10,696 and 10,249 were evaluable for safety and efficacy analyses, respectively. The median duration of exposure was 1096 days. ADRs occurred in 412 patients (3.85%) and were serious in 117 patients (1.09%). The most frequent ADR class was gastrointestinal disorders (0.68%), which included constipation. There were no new ADRs warranting attention beyond those already described in teneligliptin's package insert. ADRs and serious ADRs in renal function subgroups occurred in 3.24-7.14% and 0.65-5.36% in G1-G5, and 4.49% and 1.92% in patients on dialysis, respectively. Reduction in HbA1c was sustained for 3 years after starting teneligliptin (- 0.70% ± 1.36%, p < 0.001 at 3 years). The least-squares mean changes in HbA1c adjusted for baseline were - 0.76% to - 0.66% in G1-G5 at 3 years. Glycated albumin levels decreased in patients on dialysis (- 2.92% ± 4.78% at 3 years).ConclusionThere were no new safety or efficacy concerns about teneligliptin used in long-term, real-world, clinical settings in patients with T2DM with any stages of renal impairment.Trial registrationJapan Pharmaceutical Information Center clinical trials database identifier: Japic CTI-153047.

Project description:IntroductionThis long-term post-marketing surveillance (SAPPHIRE) collected information on the safety and effectiveness of canagliflozin (approved dose 100 mg) prescribed to patients with type 2 diabetes mellitus (T2DM) in real-world practice in Japan.MethodsPatients with T2DM who were prescribed canagliflozin between December 2014 and September 2016 were registered and observed for up to 3 years. Safety was evaluated in terms of adverse drug reactions (ADRs). Effectiveness was assessed in terms of glycaemic control. Data were also analysed across age subgroups (< 65, ≥ 65 to < 75, and ≥ 75 years old) and the estimated glomerular filtration rate (eGFR) categories for chronic kidney disease (G1-G5 based on eGFR) at baseline.ResultsA total of 12,227 patients were included in the safety analyses and 11,675 in effectiveness analyses. Overall, 7104 patients were treated with canagliflozin for ≥ 3 years. The mean age, haemoglobin A1c (HbA1c), and eGFR at baseline were 58.4 ± 12.5 years, 8.01 ± 1.49%, and 80.04 ± 21.85 mL/min/1.73 m2, respectively. There were 1836 ADRs in 1312 patients (10.73%) and 268 serious ADRs in 225 patients (1.84%). The most common ADRs were those related to volume depletion (1.39%), genital infection (1.34%), polyuria/pollakiuria (1.23%), and urinary tract infection (1.19%). The frequencies of ADRs tended to increase with age and stage of chronic kidney disease. The reductions in mean HbA1c after starting canagliflozin were maintained for up to 3 years with a mean change of - 0.68% (n = 6345 at 3 years). Maintained reductions in mean HbA1c were observed in each age subgroup and in patients with G1-G3b renal function.ConclusionThis surveillance in real-world clinical practice showed that canagliflozin provides sustained glucose-lowering effects in patients with T2DM, including elderly patients and patients with moderate renal impairment, without new safety concerns beyond those already described in the Japanese package insert.Trial registrationJapicCTI-153048.

Project description:IntroductionGolimumab is a human monoclonal antibody that inhibits tumor necrosis factor-α (TNF-α). Inhibition of TNF-α by golimumab inhibits the inflammatory response, thereby modulating the immune response in immune-mediated inflammatory diseases. Although the efficacy of golimumab has been demonstrated in randomized controlled trials (RCTs), various patient populations, such as those at high risk of infection, including those with latent tuberculosis and various comorbidities, or on co-administered medications, were excluded from the RCTs. Therefore, safety cannot be sufficiently evaluated by RCTs in the patient group with heterogenous characteristics. The aim of this study was to assess the safety and effectiveness of golimumab in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondyloarthritis (AS) in a real-world setting in Korea.MethodsWe conducted an open-label, prospective, non-interventional study as post-marketing surveillance. Safety was evaluated by collecting and recording adverse events, and effectiveness was evaluated by assessing disease activity using DAS28-CRP, DAS28-ESR, ACR20, and ASAS20 outcome measures. Multiple logistic regression was performed to identify factors associated with the incidence of adverse events, and changes in disease activity scores from baseline were analyzed using the Wilcoxon signed-rank test.ResultsA total 673 patients were enrolled, of whom 621 were included in the safety analysis. During the study, 97 adverse drug reactions (ADRs) were reported in 62 patients (10.0%). The most frequently reported ADRs were related to infection, including nasopharyngitis (0.8%), upper respiratory tract infection (0.6%), and herpes zoster (0.5%). The mean (± standard deviation) changes from baseline in global disease activity at weeks 12 and 24 were - 3.37 ± 2.529 and - 3.68 ± 2.404, respectively, with statistical significance. In those patients with RA, 72.5 and 47.0% of individuals had a good response based on DAS28-CRP and DAS28-ESR outcomes at week 24. At week 24, 71.4% of patients with PsA had an ACR20 response and 72.9% of patients with AS had an ASAS20 response.ConclusionIn the real-world setting, golimumab was safe and effective in Korean patients with RA, PsA, and AS.
