# Care Coordination for Mosunetuzumab Therapy in Patients With Follicular Lymphoma in Community Practices: Learnings From the MorningSun Study Investigators

## TL;DR

The study explores how community practices in the US coordinated care for patients receiving mosunetuzumab therapy, highlighting strategies for managing side effects and improving workflow.

## Contribution

The paper provides practical insights into implementing bispecific antibody therapy in community settings, emphasizing staff education and patient monitoring.

## Key findings

- Most community practices provided in-service training for staff administering bispecific antibodies.
- Multidisciplinary plans were used by most practices to address logistical concerns.
- Patient education and self-monitoring devices were emphasized for managing cytokine release syndrome.

## Abstract

Preliminary data from the MorningSun study have demonstrated that outpatient subcutaneous mosunetuzumab can be safely administered.

This publication describes how community centers in the MorningSun phase 2 study of outpatient subcutaneous mosunetuzumab in B‐cell non‐Hodgkin lymphomas prepared workflow and logistics (staff coordination, practice networks, and patient support) to monitor patients for cytokine release syndrome (CRS) and other toxicities.

Ten investigators at US community practice study sites (one rural, seven urban, and two rural/urban) were interviewed between January 12 and February 22, 2024. Interview transcripts were analyzed qualitatively to identify key themes.

Prior to the study, 7/10 had limited/no experience administering bispecific antibodies for lymphoma. Regarding preparation before treatment, staff education was the most frequent need (7/10). All sites provided in‐service training for staff involved with treatment administration. Most respondents (6/10) had multidisciplinary plans and agreed these eased logistical concerns. Out of hours, patients either called the triage team, a dedicated on‐call number, the physician, or the emergency department. Most practices had preexisting relationships with hospitals for CRS management. All practices established methods for outpatient CRS monitoring; patient education and caregivers played important roles, and all respondents encouraged patients to use self‐monitoring devices. Each community practice had different workflow and logistics based on their setting and infrastructure.

Community practices can leverage other sites' experiences and adopt an individualized approach to implementing bispecific antibodies safely and efficiently. Designating a physician champion could provide a local resource to address staff questions and concerns.
