The steroid-sparing effects of a mycophenolate mofetil-based regimen in the management of immunoglobulin A nephropathy in patients with histologically active lesions: A comparison with a control cohort receiving conventional therapy

INTRODUCTION

While the use of different immunosuppressants has been investigated in immunoglobulin A nephropathy, further investigation is needed to assess the effect of a regimen of mycophenolate mofetil combined with a short course of glucocorticosteroids in the subset of patients with histologically active features. We compared the efficacy and safety of a combined regimen of mycophenolate mofetil and glucocorticosteroids to a conventional regimen of glucocorticosteroids alone in patients with immunoglobulin A nephropathy who have active lesions and major urinary abnormalities.

METHODS

This retrospective study involved 30 immunoglobulin A nephropathy patients with active histological lesions, 15 of whom were treated with both mycophenolate mofetil 2 g/day for 6 months and 3 pulses of 15 mg/kg methylprednisolone, followed by a short tapering schedule of oral prednisone. The control group was made up of the remaining 15 clinically- and histologically-matched patients treated with glucocorticosteroids alone according to a validated schedule, i.e., 1 g of methylprednisolone given intravenously for 3 consecutive days, followed by oral prednisone 0.5 mg/kg every other day for 6 months. At diagnosis, all patients had urinary protein excretion > 1 g/24 h and microscopic hematuria.

RESULTS

At the end of the first year of follow-up (30 patients) and after 5 years (17 patients), there were no differences between the two groups in terms of urinary abnormalities and functional parameters. Both regimens achieved a statistically significant decrease in 24-h urinary protein excretion (p < 0.001) and a reduction of microscopic hematuria. However, the mycophenolate mofetil-based regimen allowed a cumulative sparing dose of 6 g of glucocorticosteroids.

CONCLUSION

In this single center study on immunoglobulin A nephropathy patients with active lesions and major urinary abnormalities and at increased risk of glucocorticosteroid-related complications, a mycophenolate mofetil-based regimen demonstrated similar outcomes in terms of complete response and relapse (at 1 and 5 years) compared to a conventional glucocorticosteroid-based protocol, while achieving a consistent reduction of glucocorticosteroid cumulative dose.

Effectiveness of Palonosetron, 1-Day Dexamethasone, and Aprepitant in Patients Undergoing Carboplatin-Based Chemotherapy

INTRODUCTION

Dexamethasone (DEX)-sparing strategy with 5-hydroxytryptamine-3 receptor antagonist (5HT3RA) and aprepitant (APR), as triplet antiemetic prophylaxis, is associated with poor control of delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving carboplatin (CBDCA)-based chemotherapy. This study aimed to evaluate whether using palonosetron (PALO) as a 5HT3RA provides superior control with CINV than first-generation (1st) 5HT3RA in triplet antiemetic prophylaxis with a DEX-sparing strategy.

METHODS

Pooled patient-level data from a nationwide, multicenter, and prospective observational study were analyzed to compare the incidence of CINV between patients administered PALO and 1st 5HT3RA in combination with 1-day DEX and APR.

RESULTS

No significant differences were observed in the incidence of CINV, pattern of CINV, or severity of nausea by type of 5HT3RA in triplet antiemetic prophylaxis with DEX-sparing strategy. In both groups, the incidence of nausea gradually increased from day 3, peaked on day 4 or 5, and then declined slowly. The visual analog scale scores in the delayed phase remained high throughout the 7-day observation period.

CONCLUSION

Careful patient selection and symptom monitoring are needed when implementing the DEX-sparing strategy in triplet antiemetic prophylaxis for patients undergoing CBDCA-based chemotherapy. Furthermore, additional strategies may be needed to achieve better control of delayed CINV.

Reduction of disease activity, corticosteroids use, and healthcare resource utilisation in patients with systemic lupus erythematosus treated with belimumab in clinical practice settings: OBSErve Spain multicentre study

INTRODUCTION AND OBJECTIVES

This OBSErve Spain study, a part of the international OBSErve programme, evaluated belimumab real-world use and effectiveness following 6 months of treatment in patients with active systemic lupus erythematosus (SLE) in clinical practice in Spain.

MATERIALS AND METHODS

In this retrospective, observational study (GSK Study 200883), eligible patients with SLE receiving intravenous belimumab (10mg/kg) had their disease activity (physician assessed), SELENA-SLEDAI scores, corticosteroid use, and healthcare resource utilisation (HCRU), assessed after 6 months of treatment versus index (belimumab initiation) or 6 months pre-index.

RESULTS

Overall, 64 patients initiated belimumab, mainly due to ineffectiveness of previous treatments (78.1%) and to reduce corticosteroid use (57.8%). Following 6 months of treatment, 73.4% of patients achieved ≥20% overall clinical improvement, while only 3.1% of patients worsened. Mean (standard deviation, SD) SELENA-SLEDAI score decreased from 10.1 (6.2) at index to 4.5 (3.7) 6 months post-index. HCRU decreased from 6 months pre-index to 6 months post-index, with fewer hospitalisations (10.9% vs 4.7% patients) and ER visits (23.4% vs 9.4% patients). Mean (SD) corticosteroid dose decreased from 14.5 (12.5)mg/day at index to 6.4 (5.1)mg/day 6 months post-index.

CONCLUSIONS

Patients with SLE receiving belimumab for 6 months in real-world clinical practice in Spain experienced clinical improvements and a reduction in HCRU and corticosteroid dose.

Outcomes of adalimumab therapy in refractory punctate inner choroidopathy and multifocal choroiditis

PURPOSE

This study aims to evaluate the outcomes of adalimumab (ADA) therapy in patients with refractory punctate inner choroidopathy (PIC) and multifocal choroiditis (MFC).

METHODS

Demographic and clinical data, including LogMAR best-corrected visual acuity (BCVA), were retrospectively collected. Doses of prednisone, immunomodulatory therapies (IMT), and anti-vascular endothelial growth factor (VEGF) injections before and after baseline (ADA initiation) were recorded, as well as the time to clinical remission, time to first flare, and drug-associated adverse events.

RESULTS

Seven patients (4 females, ten eyes) were included. The mean follow-up after baseline was 17.8 ± 11.1 months (range 6-33). The mean LogMAR BCVA was 0.35 ± 0.77 at 6 months before baseline and remained stable throughout 12 months after baseline (0.31 ± 0.46 at 12 months; p = 0.47). The mean dose of prednisone decreased from 17.3 ± 19.6 mg/day 6 months before baseline (range 0-60) to 2.6 ± 2.4 mg/day at the last follow-up (range 0-6, p = 0.03). The mean number of flares decreased significantly from 1.43 ± 0.79 over a 6-month period before baseline to 0.2 ± 0.45 (p = 0.02) at 6-12 months after baseline. The mean number of anti-VEGF injections was 4.17 ± 3.92 over the 12-month period before baseline, and it was 2.17 ± 3.06 (p = 0.31) during the first 12 months after baseline. No adalimumab-related adverse events were noted.

CONCLUSION

Adalimumab therapy for refractory PIC/MFC enabled a significant steroid-sparing effect, decreased disease flares, and preserved vision over a mean follow-up of 17.8 months.

Efficacy of one-day versus multiple-day dexamethasone for chemotherapy-induced nausea and vomiting in lung cancer patients receiving carboplatin-based chemotherapy: a propensity score-matched analysis

PURPOSE

Dexamethasone (DEX)-sparing strategies (one-day DEX) with palonosetron as doublet antiemetic prophylaxis have previously been studied. However, DEX-sparing regimens with 5-hydroxytryptamine-3 receptor antagonist (5-HT₃RA) and aprepitant (APR), as triplet antiemetic prophylaxis, have not been evaluated. This study aimed to evaluate the efficacy of a combination of 5-HT₃RA, APR, and DEX on day 1 of carboplatin (CBDCA)-based chemotherapy in patients with lung cancer.

METHODS

Data were pooled from a nationwide, multicenter, prospective observational study using propensity score-matched analysis to compare the incidence of chemotherapy-induced nausea and vomiting (CINV) between one- and multiple-day DEX regimens in combination with 5-HT₃RA plus APR.

RESULTS

Incidence of delayed nausea was significantly higher in the one-day than in the multiple-day DEX group. Incidence of nausea was also significantly higher in the one-day than in the multiple-day DEX group on days 3-5. Kaplan-Meier curves for nausea showed a significant difference between the two groups; however, there was no significant difference in the occurrence of vomiting or the Kaplan-Meier curves of time to vomiting.

CONCLUSION

To the best of our knowledge, this study is the first to evaluate the efficacy of a DEX-sparing regimen by comparing one- and multiple-day DEX combined with 5-HT₃RA and APR concerning CINV incidence in lung cancer patients receiving CBDCA-based chemotherapy. Antiemetic regimens of one-day DEX result in poor control of delayed nausea; therefore, we recommend the application of the DEX-sparing strategy only after careful patient selection while considering the development of nausea.

SOURCE: a phase 3, multicentre, randomized, double-blind, placebo-controlled, parallel group trial to evaluate the efficacy and safety of tezepelumab in reducing oral corticosteroid use in adults with oral corticosteroid dependent asthma

BACKGROUND

Many patients with severe asthma continue to experience asthma symptoms and exacerbations despite standard-of-care treatment. A substantial proportion of these patients require long-term treatment with oral corticosteroids (OCS), often at high doses, which are associated with considerable multiorgan adverse effects, including metabolic disorders, osteoporosis and adrenal insufficiency. Tezepelumab is a human monoclonal antibody that blocks the activity of the epithelial cytokine thymic stromal lymphopoietin. In the PATHWAY phase 2b study (NCT02054130), tezepelumab significantly reduced exacerbations by up to 71% in adults with severe, uncontrolled asthma. Several ongoing phase 3 trials (SOURCE, NCT03406078; NAVIGATOR, NCT03347279; DESTINATION, NCT03706079) are assessing the efficacy and safety of tezepelumab in patients with severe, uncontrolled asthma. Here, we describe the design and objectives of SOURCE, a phase 3 OCS-sparing study.

METHODS

SOURCE is an ongoing phase 3, multicentre, randomized, double-blind, placebo-controlled study to evaluate the effect of tezepelumab 210 mg administered subcutaneously every 4 weeks on OCS dose reduction in adults with OCS-dependent asthma. The study comprises a 2-week screening and enrolment period, followed by an OCS optimization phase of up to 8 weeks and a 48-week treatment period, which consists of a 4-week induction phase, followed by a 36-week OCS reduction phase and an 8-week maintenance phase. The primary objective is to assess the effect of tezepelumab compared with placebo in reducing the prescribed OCS maintenance dose. The key secondary objective is to assess the effect of tezepelumab on asthma exacerbation rates. Other secondary objectives include the proportion of patients with a reduction in OCS dose (100% or 50% reduction or those receiving < 5 mg) and the effect of tezepelumab on lung function and patient-reported outcomes.

CONCLUSIONS

SOURCE is evaluating the OCS-sparing potential of tezepelumab in patients with OCS-dependent asthma. SOURCE also aims to demonstrate that treatment with tezepelumab in patients with severe asthma is associated with reductions in exacerbation rates and improvements in lung function, asthma control and health-related quality of life, while reducing OCS dose.
