AI-Assisted Patient Support in mHSPC (LUMINOUS)

1 septembre 2026 mis à jour par: Bo Dai, Fudan University

Effects of Large LangUage Model-Based AI Agent-Assisted Patient-Centered Support on ANxiety, Illness PerceptiOn, and Sleep QUality in Patients With Newly Diagnosed Metastatic Hormone-Sensitive Prostate Cancer: A Multicenter, Open-Label, Randomized Controlled Trial

The purpose of this multicenter, open-label, randomized controlled trial is to evaluate whether patient-centered support delivered through a large language model (LLM)-based artificial intelligence (AI) agent reduces anxiety in patients with newly diagnosed metastatic hormone-sensitive prostate cancer (mHSPC). Participants access the AI agent through a WeChat Mini Program-based platform. The study will also assess the effects of this intervention on illness perception, sleep quality, and patient satisfaction. Participants will be randomly assigned in a 1:1 ratio to either the intervention group or the control group. Participants in the intervention group will have access to the AI agent-enabled patient support platform throughout the 4-week study period. Participants in the control group will use the same platform without access to the AI agent during the first 2 weeks and will then receive access to the AI agent for the subsequent 2 weeks. Both groups will receive standard-of-care medical treatment throughout the study. The primary objective is to compare changes from baseline in anxiety at 2 weeks between the two groups. Anxiety will be assessed using the Generalized Anxiety Disorder-7 (GAD-7) scale. Secondary outcomes include illness perception, sleep quality, and patient satisfaction. Exploratory outcomes include the change from baseline in the GAD-7 total score at 4 weeks and the accuracy of responses generated by the AI agent to participants' questions.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Immediate AI Agent Access
Participants will receive immediate access to the AI Agent for 4 weeks after randomization, in addition to standard-of-care medical treatment.
Comportemental: AI Agent-Assisted Patient-Centered Support
Participants access the AI agent through a WeChat Mini Program. It provides clinician-reviewed educational materials on prostate cancer and disease management. A large language model-based AI agent provides real-time, multi-turn, personalized responses to participants' questions. Retrieval-augmented generation based on a curated clinical knowledge base is used to improve the accuracy and clinical relevance of the responses. The AI agent will not replace physician assessment, diagnosis, or treatment decision-making.
Médicament: Standard-of-Care Medical Treatment
Participants will continue to receive standard-of-care medical treatment for mHSPC throughout the study. Treatment may include androgen deprivation therapy (ADT) in combination with an androgen receptor pathway inhibitor (ARPi), and bone-protective agents may also be administered, as determined by the treating physician according to clinical guidelines and individual patient needs. However, radiotherapy, surgery, or chemotherapy in any form is not permitted during the study period. Non-antineoplastic medications taken prior to enrollment may be continued during the study.
Comparateur actif: Delayed AI Agent Access
Participants will use the same platform without access to the AI agent during the first 2 weeks after randomization, in addition to standard-of-care medical treatment. After completing the 2-week assessments, participants will receive access to the AI agent for the remaining 2 weeks.
Médicament: Standard-of-Care Medical Treatment
Participants will continue to receive standard-of-care medical treatment for mHSPC throughout the study. Treatment may include androgen deprivation therapy (ADT) in combination with an androgen receptor pathway inhibitor (ARPi), and bone-protective agents may also be administered, as determined by the treating physician according to clinical guidelines and individual patient needs. However, radiotherapy, surgery, or chemotherapy in any form is not permitted during the study period. Non-antineoplastic medications taken prior to enrollment may be continued during the study.
Comportemental: The Same Platform without AI Agent
The basic platform supports study registration, assessments, and usage tracking but does not provide AI agent function during the first 2 weeks.
Comportemental: Delayed AI Agent-Assisted Patient-Centered Support
Participants will receive access of AI agent after completing the 2-week assessments. The AI agent is accessible through a WeChat Mini Program. It provides clinician-reviewed educational materials on prostate cancer and disease management. A large language model-based AI agent provides real-time, multi-turn, personalized responses to participants' questions.

The Brief Illness Perception Questionnaire (B-IPQ) assesses cognitive and emotional representations of illness. Eight scored items are rated from 0 to 10. After appropriate reverse scoring, the total score ranges from 0 to 80, with higher scores indicating a more threatening perception of the illness. Change from baseline is calculated as the score at 2 weeks minus the baseline score, with negative values indicating improvement. The mean change from baseline will be compared between the two groups.
At baseline and 2 weeks after randomization.
Between-Group Difference in Change from Baseline in the Insomnia Severity Index (ISI) Total Score at 2 Weeks
Délai: At baseline and 2 weeks after randomization.
The Insomnia Severity Index (ISI) assesses insomnia severity using 7 items, each scored from 0 to 4. The total score ranges from 0 to 28, with higher scores indicating greater insomnia severity.
