Rapid infusion rituximab is well tolerated in patients with primary CNS lymphoma

Effects of an Ocrevus Rapid Infusion Protocol: A Literature Review and Quality Improvement Project

The administration of Ocrevus, an infusion therapy for the treatment of multiple sclerosis, is time and labor intensive, leading to poor patient adherence, treatment delays due to scheduling issues, and significant staff workload. This problem worsened during the COVID-19 pandemic, which created scheduling difficulties due to space restrictions. A US Food and Drug Administration-approved rapid infusion protocol for Ocrevus decreases the infusion time by 1.5 hours per patient. The purpose of this project was to complete a literature review on rapid infusion protocols and analyze the effects of the Ocrevus rapid infusion protocol on 2 outcomes of interest: total visit time and infusion reaction rates. Data were collected using retrospective chart review and analyzed by comparing the results of each outcome to the same data points prior to the implementation of the project. Results found a statistically significant decrease in visit time, with no increase in infusion reaction rates. These findings support the implementation of this rapid Ocrevus infusion protocol in the outpatient setting with the potential to improve patient scheduling, patient satisfaction, and nursing workload, while maintaining patient safety.

Safety of recombinant human hyaluronidase PH20 for subcutaneous drug delivery

INTRODUCTION

The glycosaminoglycan hyaluronan forms a gel-like substance, which presents a barrier to bulk fluid flow in the subcutaneous (SC) space, limiting SC drug delivery volume and administration rates. Recombinant human hyaluronidase PH20 (rHuPH20) acts locally to temporarily remove this barrier, facilitating rapid SC delivery of large volumes and/or high doses of sequentially or co-administered therapeutics.

AREAS COVERED

An extensive clinical and post-marketing dataset of safety and immunogenicity of rHuPH20 in its current applications with approved therapeutics demonstrates that rHuPH20 acts locally, without measurable systemic absorption at the SC doses used in the approved products, and is well tolerated in combination with several co-administered therapeutic agents across diverse patient groups. The immunogenicity profile demonstrates no adverse effects associated with treatment-emergent rHuPH20 antibody responses. Immunogenicity to monoclonal antibodies co-formulated with rHuPH20 shows no clinical difference between SC and intravenous administration. Safety assessments of patient subsets for special populations, including children, elderly patients, and pregnant women, raise no additional safety concerns.

EXPERT OPINION

The benefits of SC administration for patients and healthcare systems often outweigh those of intravenous administration, driving future initiation of SC-only drug development programs. Injection devices allowing large-volume SC administration could be facilitated by incorporating co-formulated biologics containing rHuPH20.

Clinical strategies for optimizing infusion center care through a pandemic

The national pandemic resulting from the novel coronavirus, COVID-19, has made the delivery of care for patients with cancer a challenge. There are competing risks of mortality from cancer versus serious complications and higher risk of death from COVID-19 in immunocompromised hosts. Furthermore, compounding these concerns is the inadequate supply of personal protective equipment, decreased hospital capacity, and paucity of effective treatments or vaccines to date for COVID-19. Guidance measures and recommendations have been published by national organizations aiming to facilitate the delivery of care in a safe and effective manner, many of which, are permanently adoptable interventions. Given the critical importance to continue chemotherapy, there remains additional interventions to further enhance patient safety while conserving healthcare resources such as adjustments in medication administration, reduction in laboratory or drug monitoring, and home delivery of specialty infusions. In this manuscript, we outline how to implement these actionable interventions of chemotherapy and supportive care delivery to further enhance the current precautionary measures while maintaining safe and effective patient care. Coupled with current published standards, these strategies can help alleviate the numerous challenges associated with this pandemic.
