NCT07708636

Brief Summary

This study is being done to evaluate whether cancer patients can safely and reliably receive proton radiation therapy while positioned upright. Proton therapy is an established form of radiation treatment, and the upright treatment system used in this study has been cleared by the U.S. Food and Drug Administration. The intent of this protocol is to observe the treatment methods, doses, and outcomes for the initial cohorts of patients treated with this upright device. This study will support research activities and evaluate feasibility as needed. Results of this study will be reported in the scientific literature but the investigators do not intend to report to the FDA for a new use or indication or change to the labeling; nor are the investigators required to do so.

Conditions

Outcome Measures

Primary Outcomes (1)

  • Feasibility of upright proton therapy

    Feasibility is defined by the proportion of evaluable patients who complete a technically successful course of upright proton therapy. Technically successful course of upright proton therapy is defined as ≥80% of prescribed proton fractions delivered with upright proton therapy. Feasible if ≥70% of evaluable cases meet technically successful criterion.

    End of proton therapy (3 months)

Secondary Outcomes (3)

  • Quality of Life (FACT-G)

    Baseline and end of proton therapy (3 months)

  • Treatment Satisfaction (FACIT-TS-G)

    End of proton therapy (3 months)

  • Comfort/Stability Survey at Simulation

    Baseline

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

(i) Up to 450 participants are expected to be enrolled at Stanford-affiliated site(s). (ii) The total number of participants expected to enroll across all sites is 450, as this is a single-site study conducted at Stanford-affiliated facilities. (iii) Participants will be pediatric and adult patients with cancer who are being considered for treatment with upright proton therapy as part of their standard clinical care. These participants are appropriate for the study because the purpose is to evaluate the feasibility of delivering upright proton therapy in patients who would otherwise be eligible for proton radiation treatment.

You may qualify if:

  • Any cancer patient (children and adults) recommended for proton therapy.
  • Participation in other clinical trials is allowed (including randomized trials of protons versus other treatments)
