Morning light to improve sleep and reduce inflammation in multiple myeloma patients after stem cell transplant

Official title: Systematic Light Exposure Effects on Circadian Rhythms Entrainment, Inflammation, Neutropenic Fever and Symptom Burden among Multiple Myeloma Patients undergoing Autologous Stem Cell Transplantation

Funded at Icahn School of Medicine at Mount Sinai · NIH-11384508 · Data updated 2026-11-12

A multi-site study will test whether exposure to circadian-friendly morning light helps multiple myeloma patients recover after autologous stem cell transplantation by improving sleep and reducing inflammation.

Who could benefit from this research

Could help

Adults with multiple myeloma undergoing autologous stem cell transplantation who are hospitalized for recovery.

Less likely to help

Some patients may not experience meaningful benefits due to individual or clinical differences or room feasibility.

What this research studies

This trial builds on prior work showing that morning light can help regulate circadian rhythms and lower inflammation in hospitalized patients. Participants will be randomly assigned to receive morning light exposure in their hospital rooms or a comparison condition, with outcomes including sleep quality, mood, neutropenic fever rates, and levels of inflammatory markers. The study will track these measures across the post-transplant recovery period to see if the light exposure translates into meaningful clinical benefits. The approach is designed to be feasible in hospital settings and could be adopted in standard post-transplant care if successful.

Why it matters

Potential benefit: If effective, this intervention could improve sleep and mood and reduce infection-related complications after stem cell transplantation.

How similar studies have gone: Earlier R21 work suggested morning light improved melatonin, mood, and inflammatory markers, supporting progression to a larger RCT.
