About this study

Official title: Impact of Concurrent Diabetes on Quality-of-life Changes During Immunotherapy - A Prospective Longitudinal Study

The goal of this observational study is to see how type 2 diabetes affects quality of life in cancer patients receiving immunotherapy. We want to know if patients with diabetes have a greater decline in quality of life over six months compared to those without. The main question we aim to answer is:

  • How does quality of life change over six months in patients with versus without diabetes?

Participants will complete quality-of-life surveys at the start, then at 3 and 6 months. This will help us see if diabetes adds extra challenges during cancer treatment

Read the detailed description

Immune checkpoint inhibitors (ICIs) have transformed the management of multiple solid malignancies by improving survival and enabling durable disease control. By targeting inhibitory immune checkpoints such as PD-1, PD-L1, and CTLA-4, these therapies enhance anti-tumour immune responses. However, immune activation may also result in immune-related adverse events (irAEs), which can affect multiple organ systems and range from mild to life-threatening. As survival improves, long-term and chronic toxicities are increasingly recognised, highlighting the importance of patient-centred outcomes such as health-related quality of life (HRQoL).

Diabetes mellitus (DM) is a common comorbidity among patients with cancer and is associated with increased symptom burden, functional impairment, and reduced HRQoL. Type 2 diabetes (T2D) has also been associated with adverse cancer outcomes and may influence both the effectiveness and toxicity profile of systemic anticancer therapy, including ICIs. In addition, ICIs can induce immune-related diabetes mellitus (ir-DM), a rare but clinically significant form of new-onset insulin-dependent diabetes requiring lifelong insulin treatment. Despite its clinical relevance, the interaction between pre-existing diabetes, ICI therapy, and longitudinal HRQoL remains insufficiently characterised.

Although HRQoL is generally reported to remain stable during ICI therapy in unselected cancer populations, it is unknown whether similar patterns are observed in patients with pre-existing DM or in those who develop ir-DM during treatment. Given the metabolic, functional, and psychosocial burden associated with diabetes, this patient group may be particularly vulnerable to deterioration in HRQoL during immunotherapy.

The primary aim of this study is to compare longitudinal changes in HRQoL between patients with T2D and non-diabetic patients from baseline to 3 and 6 months after initiation of ICI therapy. The primary hypothesis is that patients with T2D will experience a greater decline in HRQoL over the first six months of treatment compared with non-diabetic patients.

This is a prospective, multicentre cohort study of adult cancer patients initiating ICI therapy. Data will be collected prospectively using a secure electronic case report form across participating centres.

At baseline, demographic characteristics, cancer type and stage, treatment intent and planned ICI regimen, diabetes status (no diabetes, type 1 diabetes, or type 2 diabetes), diabetes treatment status, performance status, and baseline patient-reported outcomes will be recorded.

During follow-up, data will be collected on ICI exposure, treatment discontinuation and reasons for discontinuation, immune-related adverse events, hospitalisations, disease progression, survival status, and the occurrence of immune-related diabetes mellitus.

Patient-reported outcomes will be assessed using the EORTC QLQ-C30 and EQ-5D-5L questionnaires in all participants, and the PAID questionnaire in participants with diabetes. Assessments will be performed at baseline and at 3 and 6 months after treatment initiation.

Immune-related diabetes mellitus will be defined as new-onset insulin-dependent diabetes occurring after initiation of ICI therapy and consistent with marked beta-cell failure, classified according to established international clinical recommendations.

This study will provide prospective real-world data on HRQoL trajectories and survival among cancer patients with and without diabetes receiving ICI therapy, and will estimate the incidence and clinical characteristics of immune-related diabetes mellitus in a nationwide setting.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in EORTC QLQ-C30 Global Health Status score

    Change in health-related quality of life measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Global Health Status scale. Scores range from 0 to 100, with higher scores indicating better global quality of life. The outcome compares changes from baseline between patients with type 2 diabetes and patients without diabetes receiving immune checkpoint inhibitor (ICI) therapy.

    Measured: Baseline, 3 months and 6 months

Secondary outcomes (8)
  1. Change in EQ-5D-5L Index Value

    Health status measured using the EuroQol 5-Dimension 5-Level questionnaire (EQ-5D-5L). The index value is derived from the five EQ-5D dimensions using a population value set, where higher values indicate better health status.

    Measured: Baseline to 3 months and 6 months

  2. Change in EQ-5D-5L Visual Analogue Scale (EQ-VAS) score

    Self-rated health measured using the EQ-5D-5L visual analogue scale (EQ-VAS), where participants rate their health from 0 (worst imaginable health) to 100 (best imaginable health).

    Measured: Baseline, 3 months and 6 months

  3. Incidence of immune-related diabetes mellitus

    Incidence of immune-related diabetes mellitus within 12 months of ICI initiation (number and proportion). Record occurrence of diabetic ketoacidosis at immune-related diabetes mellitus onset.

    Measured: Within 12 months after initiation of ICI.

  4. Hospital Admissions

    Number and type of hospital admissions within 6 months of ICI initiation, categorized Immune-related adverse event related, diabetes-related, or other. Derived measures include time to first hospitalization and length of stay.

    Measured: Within 6 months after initiation of ICI therapy.

  5. Time to Treatment Failure

    Time from first dose of immune checkpoint inhibitor (ICI) therapy to permanent discontinuation of ICI therapy for any reason (including disease progression, toxicity, or other causes) or death, whichever occurs first.

    Measured: Within 6 months after initiation of immune checkpoint inhibitor therapy

  6. Time to death from any cause (Overall Survival)

    Overall survival defined as time from initiation of ICI therapy to death from any cause.

    Measured: Within 12 months after initiation of immune checkpoint inhibitor therapy

  7. Association Between Clinical Events and HRQoL Outcomes

    Exploratory analyses examining associations between clinical events (e.g., hospitalizations and immune-related adverse events) and changes in health-related quality of life measured using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Scores range from 0 to 100, with higher scores indicating better global health status and quality of life.

    Measured: Baseline to 6 months

  8. Change in Problem Areas in Diabetes Score

    Change in diabetes-related emotional distress measured by the Problem Areas in Diabetes (PAID) questionnaire. The PAID questionnaire assesses diabetes-specific emotional distress, with higher scores indicating greater distress. This outcome is assessed in participants with diabetes.

    Measured: Baseline to 6 months (assessed at baseline, 3 months, and 6 months)
