  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age 18 - 65 years at time of screening
  • A clinical diagnosis of type 1 diabetes for 2 years or more as determined by the medical record or other source documentation by a health care professional qualified to make a diagnosis.
  • HbA1c of >= 9.0% in last 6 months.

  • Willing to follow study specific instructions and improve glucose control.
  • Willing to use CamAPS FX continuously throughout the study.
  • Female participants of child-bearing age should be on effective contraception and must have a negative urine-HCG pregnancy test at screening
  • Psychological problems defined as one of the following:
  • Diabetes Distress Scale (DDS-17) - assesses diabetes-specific emotional distress across four domains: Emotional Burden, Physician-Related Distress, Regimen-Related Distress, and Interpersonal Distress. Scale: 1- 6. Scores ≥2.0 indicate moderate distress.
  • Problem Areas in Diabetes (PAID) Scale - measures overall emotional burden related to diabetes. Scale: 0-100. Total scores ≥40 indicate clinically significant diabetes distress.
  • Diabetes Burnout Questionnaire (DBQ) - evaluates emotional exhaustion, detachment from diabetes care, and perceived loss of control. Scale: 1-5. Scores >2 suggest clinically relevant burnout symptoms.
  • Quick Inventory of Depressive Symptomatology (QIDS) - assesses depressive symptoms over the previous week. Scale: 0-27. Scores ≥6 are considered indicative of clinically relevant depressive symptoms, with higher score ranges reflecting increasing symptom severity.
  • Patient Health Questionnaire-9 (PHQ-9) - assesses depressive symptoms over the preceding two weeks. Scale: 0-27. Scores ≥10 indicate clinically relevant depression.
  • WHO-5 Well-Being Index - measures positive well-being. Scale: 0-25. Scores ≤13 indicate reduced well-being.
  • Hypoglycaemia Fear Survey (HFS-II) - assesses behaviours and concerns related to hypoglycaemia; in the Polish version of the Hypoglycaemia Fear Survey-II. Scale: 0-132. Scores above 40 are commonly used to indicate elevated fear of hypoglycaemia.
  • EQ-5D-5L (EuroQol Group, 2011) - evaluates health-related quality of life across five dimensions and includes a visual analogue scale (VAS 0-100), values below 50 considered indicative of markedly reduced perceived health status.
  • Symptom Questionnaire (KO "0") - used to assess anxiety-related psychological symptoms. Scale: 0-336. Scores above normative thresholds (180 for males, 200 for females) indicate clinically relevant anxiety symptomatology.

Who cannot join

About this study

Official title: The Impact of Introducing Hybrid Closed-loop Pump Therapy on Glucose Control, Quality of Life and Selected Chronic Complications in Type 1 Diabetes Patients With Chronically High Glucose Level and Psychological Problems

The objective of this study is to evaluate whether the mylife CamAPS FX hybrid closed loop (HCL) system improves glycemic control and quality of life in type 1 diabetes (T1DM) patients with a chronic lack of glycemic control and with psychological problems.

After screening visit and run-in, patients will be randomized to treatment with mylife CamAPS FX HCL for 12 months (group I) or treatment with their current type of treatment for 3 months and mylife CamAPS FX HCL for next 9 months (group II). The HCL system used in the study will consist of mylife CamAPS FX controller, mylife YpsoPump insulin pump and Dexcom G6 continuous glucose monitoring system (CGM).

Main inclusion criteria include: type 1 diabetes for at least 2 years, hemoglobin A1c (HbA1c) ≥ 9.0%, and psychological vulnerability.

Primary glycemic outcomes include: differences between study groups in changes in time in range 70-180 mg/dL (TIR) and HbA1c after 3 months.

Main secondary outcomes include: differences between groups in CGM-derived data after 3 months and within the entire cohort after 12 months, as well as changes within groups in psychological scores after 3 months and within the entire cohort after 12 months.

Read the detailed description

Estimated sample size needed to provide 80% power to detect a difference in:

  • in time spent in range between studied groups at 3 months, if baseline TIR is 30% and expected 60%, pooled SD of 20%,, with a two-sided significance level of 0.05, the sample is 20 (10 in each group).
  • in HbA1c between studied groups at 3 months, if baseline mean HbA1c is 9.5% and expected mean HbA1c is 7.5%, with pooled SD of 1.5% with a two -sided significance level of 0.05, is 20 (10 in each group)

Randomization in 1:1 ratio to either mylife CamAPS FX HCL or continuation of optimised pre-study insulin therapy regimen, using the big stick method with a maximum tolerated imbalance of 3. The allocation sequence generated using the Clinical Trial Randomization Tool, and study personnel responsible for participant enrollment and assignment with no access to the randomization sequence.

Funding Investigator-initiated study; device support provided by mylife Diabetes Care,, without influence on study design, analysis, or reporting.

Note: The study protocol was approved by the Bioethics Committee on 29 April 2024. Registration at ClinicalTrials.gov was completed after participant enrolment had begun due to an institutional discussion within the University Hospital in Krakow regarding the registration process. This delay was caused by a discrepancy between the definition of a clinical trial under Polish law - where the term applies solely to studies involving unregistered drugs or devices - and the broader definition commonly used in the scientific community.

Questions about this trial

What is this clinical trial studying?

A study testing mylife CamAPS FX hybrid closed-loop system in people with Type 1 Diabetes Mellitus, run by Jerzy Hohendorff at 3 sites in Poland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 3 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HbA1c (time frame: 3 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2026; AzTrials last refreshed its copy on 7 Nov 2026.
