Smoot K, Marginean H, Gervasi-Follmar T, Chen C. Comparing the Risk of Infusion-Related Reactions and Tolerability in Patients Given Cetirizine or Diphenhydramine Prior to Ocrelizumab Infusion (PRECEPT). MEDICINA (KAUNAS, LITHUANIA) 2024; 60:659. [PMID: 38674305 PMCID: PMC11051876 DOI: 10.3390/medicina60040659] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/22/2024] [Revised: 04/15/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024]
Abstract
Background: Ocrelizumab is an effective medication for multiple sclerosis. However, infusion-related reactions (IRRs) are a concern for patients and may lead to discontinuation of ocrelizumab. To minimize IRRs, pre-medications are administered. However, from our experience, these medications, especially diphenhydramine, can cause marked drowsiness. The primary objective of this study was to evaluate whether cetirizine is non-inferior to diphenhydramine in limiting the proportion and severity of reactions from ocrelizumab infusions. Methods: Twenty participants were serially randomized in a 1:1 ratio to receive 10 mg of cetirizine or 25 mg of diphenhydramine orally prior to their first three ocrelizumab infusions. Results: The rate of IRRs in this study was similar across both treatment groups with no increase in the risk of severity, and no grade 3 IRRs. Further, patients receiving cetirizine experienced a reduction in fatigue. While there was not a significant difference in global satisfaction, this score increased over time in the cetirizine arm while it remained unchanged in the diphenhydramine arm. Conclusions: Overall, our results suggest that cetirizine does not increase the risk of infusion-related reactions compared to diphenhydramine.

Nishiura H, Takahashi M, Mori K, Sugimoto T, Emoto M, Nakamura Y. Patients with infusion-related reactions on fixed-dose rituximab treatment have higher body surface area than those without infusion-related reactions in adults with frequently relapsing minimal change nephrotic syndrome: a retrospective study. J Pharm Health Care Sci 2024; 10:12. [PMID: 38388462 PMCID: PMC10882848 DOI: 10.1186/s40780-024-00334-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/06/2024] [Indexed: 02/24/2024] Open
Abstract
BACKGROUND Infusion-related reactions (IRRs) are major side effects of rituximab administration. Male sex, high body weight, body surface area (BSA), and body mass index are predictive markers of rituximab-induced IRRs. However, as rituximab was not administered at a fixed dosage in a previous study, whether a higher dosage or factors associated with a larger physique are more strongly associated with rituximab-induced IRRs is unknown. MAIN BODY Thirteen adults with frequently relapsing minimal change nephrotic syndrome (MCNS) who received an initial rituximab dose of 500 mg between September 2015 and November 2022 were retrospectively evaluated. Data on IRRs were collected from medical records. The incidence of rituximab-induced IRRs was 38.5% (5/13). The IRR group had a significantly higher BSA than the non-IRR group (median, 1.86 vs. 1.48 m2; p = 0.045). Additionally, rituximab dosage normalized by BSA in the IRR group was significantly lower than that in the non-IRR group (median, 268.8 vs. 337.9 mg/m2; p = 0.045). CONCLUSIONS Our study revealed that adults with frequently relapsing MCNS who experienced IRRs tend to have a higher BSA, even with fixed-dose rituximab treatment. Therefore, when patients with higher BSA receive rituximab treatment, clinicians should be careful about monitoring patient condition whether the dosage is fixed or not.

Abstract
Infusion-related reactions (IRRs) are the major side effects of rituximab administration. Although several studies have reported predictive markers for IRRs in patients with malignancies, there are no such reports for patients without malignancies. Accordingly, we aimed to clarify the predictive markers for rituximab-induced IRRs in renal transplant recipients. This retrospective study included 116 inpatients aged ≥18 years who received an initial dose of 150 mg/m2 of rituximab for desensitization before renal transplantation with loxoprofen and diphenhydramine before rituximab infusion between June 2007 and February 2022. Overall, 45 patients were evaluated and 71 patients were excluded in this study. IRRs were observed in 12 (26.7%) patients. The proportion of men in the IRRs group was significantly higher than that in the non-IRRs group (p = 0.023). Additionally, body weight, body surface area (BSA), and body mass index (BMI) were significantly higher in the IRRs group than in the non-IRRs group (body weight, p = 0.0058; BSA, p = 0.0051; BMI, p = 0.017). Their cutoff values for predicting rituximab-induced IRRs, based on the receiver-operating characteristic curve, were 74.850 kg, 1.910 m2 and 24.164 kg/m2, respectively. In conclusion, the male sex, high actual body weight, BSA, and BMI may be new predictive markers for rituximab-induced IRRs in renal transplant recipients. Therefore, clinicians should carefully monitor patients who receive rituximab before renal transplantation and present with the predictive markers.

Abstract
Anti-CD20 have quickly become the mainstay in the treatment of multiple sclerosis (MS) and other neuroinflammatory conditions. However, when they are used as a maintenance therapy the balance between risks and benefits changes. In this review, we suggested six steps to derisk anti-CD20. Firstly and secondly, adequate infectious screening followed by vaccinations before starting anti-CD20 are paramount. Third, family planning needs to be discussed upfront with every woman of childbearing age. Fourth, infusion reactions should be adequately managed to avoid treatment interruption. After repeated infusions, it becomes important to detect and prevent anti-CD20-related adverse events. Fifth, we recommended measuring immunoglobulin levels and reviewing vaccinations annually as well as counselling adequate fever management. For female patients, we emphasised the importance to engage with the local breast cancer screening programs. Sixth, to fundamentally derisk anti-CD20 therapies, we need evidence-based approaches to reduce dosing intervals and guide retreatment.

Abstract
Objective Pivotal clinical trials revealed good clinical efficiency of ocrelizumab while having a good safety profile in the management of multiple sclerosis (MS). However, real-world data of ocrelizumab in daily clinical practice remain scarce. The aim of this study was to evaluate the preliminary safety profile and effectiveness of ocrelizumab treatment for MS in an Arab population in a real-world clinical setting. Methods In this retrospective single-center observational study in Qatar, we reviewed the medical records and analyzed the clinical and MRI data of all patients with relapsing-remitting MS (RRMS) and active secondary progressive MS (aSPMS)—between October 2017 through December 2020—who had received at least one infusion of ocrelizumab (Q-OCRE). Results A total of 60 MS patients were included (57 with RRMS, three SPMS). The Median follow-up period was 19 months (range, 1–32). The most common reason for switching to ocrelizumab was increased disease activity and three-quarters of the patients were on a previous disease-modifying drug (DMD). No evidence of disease activity (NEDA) status at year 1 was achieved in 73% of the cohort. Mild infusion-related reactions (IRR) and infections were reported (mainly upper respiratory tract infections followed by urinary tract infection) with a declining percentage over the follow-up applications. No severe side effects were observed. Conclusion Our real-world experience confirms good efficacy, tolerability, and safety of ocrelizumab in our Arab population.

Abstract
BACKGROUND We aim to directly compare changes in lymphocyte subpopulations between chimeric (rituximab) and humanised (ocrelizumab) anti-CD20 antibodies in multiple sclerosis (MS). METHODS In this retrospective analysis of prospectively collected data, we included 88 patients with MS, treated with rituximab (n=50) or ocrelizumab (n=38). We used flow cytometry in the peripheral blood to count total lymphocytes and lymphocytes expressing different phenotypic markers (CD4, CD8, CD19, CD20, CD4/CD8 ratio), before treatment and after 1, 3 and 6 months. RESULTS On linear mixed effect regression models, after 1, 3 and 6 months, patients treated with rituximab and with ocrelizumab were similar in total lymphocyte count, CD19 lymphocytes, CD20 lymphocytes and CD4/CD8 ratio. However, patients treated with ocrelizumab presented with lower CD4 T lymphocytes and CD8 T lymphocytes after 1, 3 and 6 months (all p<0.05). No between-treatment difference in EDSS progression was found. DISCUSSION B-cell levels in the peripheral blood were equally decreased by rituximab and ocrelizumab. On the contrary, CD4 and CD8 T lymphocyte reduction was more pronounced in ocrelizumab, when compared with rituximab, suggesting a broader immunomodulatory effect for the humanised antibody to be confirmed and correlated with clinical efficacy in the long term.

Abstract
Objective Pivotal trial have shown that patients with multiple sclerosis (MS) receiving ocrelizumab had better outcomes. However, data on ocrelizumab in clinical practice are limited. The aim of this study was to evaluate the preliminary safety profile and effectiveness of ocrelizumab treatment for multiple sclerosis (MS) in a real‐world clinical setting. Methods We conducted a retrospective study including consecutive patients from nine public hospitals in south‐eastern Spain who received ocrelizumab after it was approved. Results A total of 228 MS patients were included (144 with relapsing–remitting MS [RRMS], 25 secondary progressive MS [SPMS], and 59 primary progressive MS [PPMS]). Median follow‐up period was 12 months (range, 1‐32). No evidence of disease activity (NEDA) status at year 1 was achieved in 91.2% of the relapsing MS (RMS) population, while disability progression was detected in 37.5% of the PPMS patients (median follow‐up period, 19 months). The most common adverse events reported were infusion‐related reactions and infections, with the most common infections being urinary tract infections followed by upper respiratory infections and COVID‐19. Interpretation The preliminary results in our real‐world setting show that ocrelizumab presented excellent results in suppressing disease activity with a favorable and consistent safety profile.

Risk factors for infusion-related reactions following Ocrelizumab infusion in a community setting: Development of an electronic medical record-based explanatory model. Mult Scler Relat Disord 2020; 48:102700.

Abstract
BACKGROUND In 2017, ocrelizumab became the first FDA approved disease modifying therapy (DMT) for primary progressive multiple sclerosis (MS). Although effective, adverse infusion-related reactions (IRR), such as erythema, pruritus, hives, and throat irritation, were frequently reported. OBJECTIVE To develop an explanatory model of factors associated with increased odds of IRR development to further enhance clinical decision-making when administering ocrelizumab in a community setting. METHODS A retrospective chart review was performed (n = 422) by extracting patient demographic factors and co-occurring conditions and symptoms from electronic medical records. Bivariate analyses were conducted to examine which demographic and clinical characteristics were associated with IRR development, and variables with a p-value of <.10 were then entered into a logistic regression to create the explanatory model. RESULTS Being female (odds ratio [OR]: 2.60), Hispanic/Latinx (OR: 3.98), and having a history of a co-occurring tremor (OR: 3.78) were risk factors for increased odds of having an IRR. CONCLUSIONS These findings may be helpful in guiding clinical practice routines and improving patient expectations regarding the likelihood of IRR development based on their individual demographics and co-occurring conditions and symptoms.

Abstract
INTRODUCTION We systematically reviewed adverse events (AEs) for ocrelizumab for multiple sclerosis (MS). AREAS COVERED We searched Medline, Embase, Web of Science, and Toxicology Data Network-TOXLINE (inception to 8-July-2020), clinical trial registries, and product monographs for any clinical trials, observational studies or case reports examining AEs to ocrelizumab. Studies with/without a comparator drug or placebo were eligible. EXPERT OPINION Seventy-eight records were included (4 randomized controlled trials (RCTs), 4 open-label trials, 29 observational studies, and 27 case reports). AEs affected 2756/4498 (61.3%) of ocrelizumab-exposed patients. The most common AEs were infections (n=1342, 39.2% of ocrelizumab-exposed patients) and infusion-related reactions (n=1391, 26.2%). Compared to beta-interferon, infections were more likely in ocrelizumab-exposed patients (Risk Ratio (RR)=1.10; 95% confidence interval (CI):1.01-1.19), including: herpes-related (RR=1.75; 95%CI:1.11-2.76), respiratory tract-related (RR=1.42; 95%CI:1.10-1.84 and RR=1.61; 95%CI:1.10-2.35), nasopharyngitis (RR=1.47; 95%CI:1.13-1.90), and rhinitis (RR=4.00; 95%CI:1.13-14.14). Infusion-related reactions (RR range: 1.57-4.42) were more common for ocrelizumab versus placebo or beta-interferon. From pooled analyses (three RCTs), the risk of 'any' serious AE did not differ significantly between the ocrelizumab and comparator groups. However, insufficient data were available to assess longer-term AEs, e.g., malignancy.

Abstract
Ocrelizumab ist ein monoklonaler Antikörper, der sich gegen das Differenzierungsantigen CD20 richtet und zu einer effektiven längerfristigen Depletion von Lymphozyten, insbesondere von B‑Zellen, führt. Unlängst publizierte Phase-3-Studien belegen, dass Ocrelizumab sowohl bei der Behandlung der schubförmigen als auch der primär progressiven Multiplen Sklerose (MS) wirksam ist. Darauf basierend wurde Ocrelizumab als erstes Medikament zur Behandlung der primär chronisch-progredienten MS zugelassen. Um diesen Durchbruch besser in den Kontext des heutigen MS-Therapiekanons einordnen zu können, lohnt sowohl ein Blick zurück auf die Entwicklung der antikörpervermittelten CD20-Depletion als auch auf die der Zulassung zugrunde liegenden Studien sowie deren Extensionsphasen. Diese Übersichtsarbeit diskutiert die verfügbaren Daten zur Wirksamkeit und Sicherheit der langfristigen B‑Zell-Depletion bei MS-Patienten und erörtert den aktuellen Kenntnisstand zur Rolle von B‑Lymphozyten in der Immunpathogenese der MS.

Abstract
IgE-mediated inflammatory responses upon allergen contact in allergic rhinitis (AR) are associated with rapid alterations of circulating blood cell numbers detectable in a complete blood count (CBC). Aim of this study was to evaluate whether intake of antihistamines may modulate allergen-induced CBC dynamics in male and female patients. A total of N = 112 specific allergen challenges were performed in otherwise healthy AR subjects. Seventy-two (n = 72) subjects received placebo and forty (n = 40) received cetirizine (H1-receptor antagonist) per os prior to allergen exposure in a randomized, double-blind trial at the Vienna Challenge Chamber (VCC); a subgroup of twenty-five (n = 25) subjects received cetirizine and placebo on different study days (parallel group). Blood samples and symptom scores were taken at baseline and immediately after 6 h of airway challenge simulating ambient allergen contact. Female sex was associated with a pronounced circulating monocyte increase (p < .01) and male sex with an eosinophil decrease (p < .05) in the placebo group, but not in cetirizine treated subjects. The significant increase in segmented neutrophils (p < .001) and decrease in circulating erythrocytes (p < .01) upon allergen challenge was less prominent after cetirizine intake in both sexes. A more prominent thrombocyte increase in female subjects (p < .05) was noted upon allergen exposure, regardless of prior cetirizine intake. Cetirizine inhibited the mobilization of neutrophils, lymphocytes and decline in erythrocyte numbers, but did not affect thrombocyte increase upon allergen challenge. It further diminished gender-specific blood cell dynamics. Overall, as reflected in a simple CBC, cetirizine critically diminished immediate and late innate immune responses subsequent to allergen exposure.

Abstract
BACKGROUND Ocrelizumab is an infusible humanized monoclonal antibody that selectively depletes CD20+ B cells. Infusion-related reactions (IRRs) were summarized from the OPERA I, OPERA II, and ORATORIO trials for relapsing and primary progressive multiple sclerosis (MS). METHODS OPERA I and OPERA II were identical, randomized, double-blind, active-controlled trials that enrolled patients with relapsing MS (RMS). Patients in the ocrelizumab group initially received two 300-mg intravenous (IV) infusions separated by 14 days (on Days 1 and 15); subsequent doses were administered as single 600-mg IV infusions. Ocrelizumab-treated patients also received subcutaneous (SC) placebo injections 3 times weekly. Patients in the active comparator group received SC injections of IFN β-1a 3 times weekly, as well as placebo infusions on Days 1 and 15 and Weeks 24, 48, and 72. ORATORIO was a randomized, parallel-group, double-blind, placebo-controlled study that enrolled patients with primary progressive MS (PPMS). As in the OPERA studies, patients in the ocrelizumab group initially received two 300-mg infusions separated by 14 days; however, ORATORIO patients continued to receive this divided-dose regimen throughout the study. The ORATORIO control group received IV placebo. Prior to each infusion, all patients in the OPERA and ORATORIO studies were pretreated with 100 mg IV methylprednisolone; additional prophylactic treatment with analgesics, antipyretics, and/or an IV or oral antihistamine was optional. IRRs were defined as adverse events that occurred during or within 24 h of IV infusion of ocrelizumab or placebo. RESULTS Safety analyses included 1651 patients with RMS from OPERA I and OPERA II (ocrelizumab, n = 825; IFN β-1a, n = 826) and 725 patients with PPMS from ORATORIO (ocrelizumab, n = 486; placebo, n = 239). Across studies, IRRs were reported in 34.3% (vs 9.7% with IFN β-1a) and 39.9% (vs 25.5% with placebo) of ocrelizumab-treated patients in the pooled OPERA and ORATORIO populations, respectively. The majority of IRRs were mild to moderate in the OPERA (ocrelizumab, 92.6%; IFN β-1a, 98.8%) and ORATORIO (ocrelizumab, 96.9%; placebo, 93.4%) studies. IRRs most commonly occurred with the first infusion. Severe IRRs were reported in 2.4% of ocrelizumab-treated patients in the OPERA studies (vs 0.1% with IFN β-1a) and 1.2% of ocrelizumab-treated patients in ORATORIO (vs 1.7% with placebo). Two serious IRRs occurred across the OPERA studies, both of which occurred with the initial infusion. The first event occurred in an IFN β-1a-treated patient in association with the initial infusion of IV placebo and consisted of severe balance disorder, dizziness, flushing, and hypoesthesia. The second event was a life-threatening reaction (bronchospasm) that occurred in an ocrelizumab-treated patient 15 min after the infusion started. Frequently reported IRR symptoms included pruritus, rash, throat irritation, and flushing. Premedication use, particularly antihistamines, was associated with fewer IRRs. CONCLUSION Findings from the OPERA I, OPERA II, and ORATORIO trials show that IRRs were the most frequently reported adverse events with ocrelizumab, were mostly mild to moderate in severity, were reduced with appropriate pretreatment, and decreased with subsequent dosing. IRRs that did occur were effectively managed through infusion rate adjustment and symptomatic treatment.
