Can a smart patch predict dangerous immune reactions in cancer treatment?
NCT ID NCT07499128
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a wearable patch called TempTraq can detect fevers earlier than standard temperature checks in cancer patients receiving immunotherapy. The goal is to see if continuous monitoring reduces the risk of severe cytokine release syndrome (CRS), a serious side effect. About 136 adults with cancer will wear the patch for up to 15 days while in the hospital. Some may also use a smartphone app to measure vital signs. The study is observational and does not provide a new treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- TempTraq wearable patch and VitalTraq app
- What this could lead to
- If successful, this could lead to earlier detection of fevers from cytokine release syndrome, potentially reducing severe complications in cancer patients receiving immunotherapy.
- What could go wrong
- This is an early-stage observational study with only 136 participants, so results may not apply to all patients. The patch monitors temperature but does not prevent CRS, and its benefit over standard care is unproven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
* INCLUSION CRITERIA: * Age \>= 18 years. * Participants must be enrolled in an active treatment protocol at NIH utilizing cellular therapy, cellular engagers, or other novel monotherapy or combination immunotherapy agents associated with a known or anticipated risk profile for grade \>= 3 cytokine release syndrome (CRS) adverse effects. * Participants must be receiving immunotherapy dose(s) and be admitted to the Clinical Center. Note: Enrollment during the first week of treatment on an active treatment protocol, when CRS risk is highest, is preferable, but starting later during their active treatment course is acceptable. * Ability of the participant to understand and the willingness to sign a written informed consent document. EXCLUSION CRITERIA: * Prior solid organ or stem cell transplantation on active immunosuppression. * Regimen including antibiotics, for documented active infection within 7 days prior to study enrollment. * Current syndrome associated with cyclic fevers. * History of severe drug allergies, including Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS). * Known current alcohol use disorder or drug use disorder that, in the opinion of the investigator, would interfere with the participant s ability to comply with study procedures or safely participate in the study.
