Narrative objectives1

We investigated patients with urothelial carcinoma receiving treatment with immune checkpoint inhibitors, focusing on: (1) body composition related to sarcopenia (such as skeletal muscle mass, muscle strength, and muscle quality), (2) skeletal muscle-related factors involved in immune regulation; (3) immune status related to resistance to ICI therapy (rate of increase in CD8+ T cells following treatment, proportion of regulatory T cells and bone marrow-derived suppressor cells, expression of immune checkpoint molecules on CD8+ T cells, etc.); and (4) ICI treatment outcomes (treatment efficacy, adverse effects, etc.), with the aim of clarifying the relationships among these factors.

Basic objectives -Others

To elucidate the relationship between body composition factors associated with sarcopenia (such as skeletal muscle mass, muscle strength, and muscle quality) and immune status factors associated with resistance to ICI therapy (such as the rate of increase in CD8+ T cells following treatment, the proportion of regulatory T cells and bone marrow-derived suppressor cells, and the expression of immune checkpoint molecules on CD8+ T cells)

Trial characteristics_1

Trial characteristics_2

Developmental phase

Primary outcomes

The relationship between body composition associated with sarcopenia and serum concentrations of skeletal muscle-related factors

Key secondary outcomes

The relationship between body composition associated with sarcopenia and immune status and immune function
The relationship between body composition associated with sarcopenia and treatment outcomes
The relationship between blood-based immune status and treatment outcomes
The relationship between skeletal muscle-related factors and treatment outcomes
The relationship between blood concentrations of skeletal muscle-related factors and immune status
The effects of serum from sarcopenia patients and skeletal muscle-related factors on immune cells

Treatment outcomes include treatment completion rate, duration of treatment, adverse events, overall survival, progression-free survival, best response, reasons for treatment discontinuation, occurrence of unscheduled visits, occurrence of unscheduled hospitalizations, relative dose intensity, and changes in quality of life (QOL).
