Guidelines for outpatient administration of naxitamab: Experience from Atrium Health Levine Children's Hospital.

ABSTRACT:

Aim

In this publication, we will share our experience of AE management, provide guidance for appropriate staffing, and the discuss the importance of patient education when treating patients with R/R HR neuroblastoma using naxitamab.

Background

Approved treatments for patients with refractory and/or relapsed (R/R) high-risk (HR) neuroblastoma are limited, and there is a high unmet need for new treatment combinations. Naxitamab is a disialoganglioside 2 (GD2)-binding antibody that was approved by the United States Food and Drug Administration in 2020 for use in combination with granulocyte-macrophage colony-stimulating factor for the treatment of patients with R/R HR neuroblastoma in the bone and/or bone marrow and who have demonstrated a partial response, minor response, or stable disease with prior therapy.

Methods

The pediatric oncology team at Atrium Health Levine Children's Hospital has successfully treated several patients with naxitamab both alone and in combination with chemotherapy, with no patients requiring unplanned overnight hospitalization and few severe adverse events (AEs). To accomplish this, the team at Levine Children's Hospital established standard operating procedures for naxitamab, a therapy defined as high acuity due to the potential for acute AEs with rapid onset and that benefits from continuous monitoring by a nursing team and a dedicated provider.

Conclusions

This will provide a practical guide for institutions offering naxitamab to their patients, and ensure successful administration of this high acuity treatment in the outpatient setting.

Project description:BackgroundPalivizumab provides passive immunity for respiratory syncytial virus (RSV), but poor adherence compromises protection. A hospital initiative promoted administration of first palivizumab doses at an outpatient clinic immediately after discharge. The objectives of this study were to evaluate the impact of the initiative on location and timing of first palivizumab dose, patient adherence, reimbursement, acquisition cost and RSV-positive hospital readmissions.MethodsThis retrospective cohort study included pediatric patients who received palivizumab from 2012 to 2016. Three groups were compared: "before initiative," "transition" and "after initiative." Patients who did not qualify for palivizumab or who were eligible for palivizumab in previous RSV seasons were excluded. Multivariable logistic and linear regressions adjusted for patients' characteristics were used in outcome analysis.ResultsAfter adjusting for patients' characteristics, there was a 13.5-fold (95% confidence interval: 5.9-30.5, P < 0.0001) increase in odds that patients would receive outpatient administration of palivizumab and 2.7-fold (95% confidence interval: 1.3-5.7, P = 0.0103) increase in odds of receiving the second dose within 35 days after initiative implementation compared with before. Although there was no significant difference in reimbursement percentage after initiative implementation (32% ± 30% after initiative and 31% ± 22% before), calculated palivizumab acquisition costs were 20.8% lower. RSV readmissions were not significantly different.ConclusionsImplementation of an initiative with defined workflow, multidisciplinary collaboration, and early case management efforts to obtain insurance authorization increased outpatient administration of first palivizumab doses. Patient adherence improved as demonstrated by more timely receipt of the second palivizumab dose. There was no difference in reimbursement; however, acquisition cost decreased which is valuable considering low reimbursement rates. RSV-positive readmissions did not change significantly.

Project description:BackgroundThe humanized anti-disialoganglioside-2 monoclonal antibody naxitamab was approved in the USA in 2020 for the treatment of patients with relapsed/refractory high-risk neuroblastoma, limited to the bone or bone marrow, in combination with granulocyte-macrophage colony-stimulating factor. Treatment with naxitamab under expanded access was initiated by physicians from the Children's Hospital of Fudan University, Shanghai, China, in August 2021.ObjectiveWe reviewed all suspected adverse reactions (ARs) reported to the Y-mAbs Argus Global Pharmacovigilance Safety Database for patients treated with naxitamab under expanded access in China from 1 August 2021 to 31 July 2022.MethodsWe assessed patient demographics and the safety profile of naxitamab over multiple treatment cycles.ResultsAt the data cutoff, 41 patients with relapsed/refractory high-risk neuroblastoma had received a total of 150 treatment cycles (451 infusions) of naxitamab. The median number of cycles completed was three; 13 patients (32%) were receiving ongoing naxitamab treatment. The median patient age was 3 years (range 1-9 years) and 63% were female. Overall, ARs were reported in 89/150 cycles (59%); serious ARs were reported in 23/150 cycles (15%). The cumulative reporting rate (ARs/cycle) decreased after 3 versus 12 months of expanded access: all ARs (8.7-4.6), serious ARs (0.9-0.3), hypotension (1.4-1.0), flushing (0.7-0.5), cough (0.6-0.3), pain (0.5-0.2), and hypoxia (0.3-0.2).ConclusionsDuring the first 12 months of expanded access treatment in China, 41 patients received naxitamab therapy with a cumulative 451 infusions administered. Over the course of this expanded access program, a reduction in the AR rate, including serious ARs, was observed as more patients were initiated and proceeded to later treatment cycles. While additional research is needed, the observed decrease in the AR rate may be attributed to clinicians' increased knowledge of AR management and hands-on experience with naxitamab-treated patients.
