About this study

Official title: A Phase 2 Randomized Trial of Pre-emptive NPH Insulin Versus Usual Reactive Diabetes Management for Preventing Hyperglycaemia After Intra-articular Triamcinolone Acetonide Injection in Adults With Type 2 Diabetes and Knee Osteoarthritis

Steroid injections used to treat painful joints can temporarily increase glucose levels in people with type 2 diabetes. This study will test whether a short course of pre-emptive neutral protamine Hagedorn, NPH, insulin can reduce high glucose after a standard corticosteroid injection into the knee.

Adults with type 2 diabetes who are scheduled to receive one intra-articular injection of triamcinolone acetonide 40 mg for knee osteoarthritis will be randomly assigned to one of two groups. The experimental group will receive a prespecified NPH insulin regimen beginning immediately after the injection and continuing for three doses. The comparison group will continue usual reactive diabetes management without pre-emptive NPH insulin.

Both groups will use blinded continuous glucose monitoring and scheduled capillary glucose testing. The main outcome is the percentage of continuous glucose monitoring time above 180 mg/dL during the first 72 hours after the corticosteroid injection. Hypoglycaemia, rescue treatment, healthcare contacts, treatment burden, acceptability and adverse events will also be assessed.

Read the detailed description

Intra-articular corticosteroid injections can produce clinically important but transient hyperglycaemia in people with type 2 diabetes. Published studies have largely characterised this glucose response rather than testing a standardised strategy to prevent it.

PREVENT-SIH is a phase 2, randomised, parallel-group trial in adults with type 2 diabetes managed without insulin or insulin secretagogues. All participants will receive a clinically indicated, standardised intra-articular injection of triamcinolone acetonide crystalline suspension 40 mg into one index knee for symptomatic knee osteoarthritis.

Participants will be randomly assigned 1:1 to a pre-emptive NPH insulin pathway or usual reactive diabetes management. The pre-emptive pathway comprises three weight-based NPH doses starting immediately after the corticosteroid injection, with prespecified glucose-based dose modification, withholding and discontinuation rules. Both groups will continue stable background diabetes medication and will receive identical blinded continuous glucose monitoring, capillary glucose monitoring, safety instructions, scheduled contacts and rescue thresholds.

Continuous glucose monitoring data will be collected for a 72-hour baseline period and for at least 96 hours after injection. The primary analysis will compare the percentage of valid readings above 180 mg/dL during the first 72 hours after injection, adjusted for baseline continuous glucose monitoring time above 180 mg/dL, site and HbA1c stratum. Rescue treatment and other post-randomisation diabetes treatment changes will be retained in the primary treatment-policy analysis.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Insulin Isophane Human, NPH, Pre-emptive AlgorithmDrug

    Also called Human NPH Insulin, Neutral Protamine Hagedorn Insulin

    Human NPH insulin U-100 will be administered subcutaneously within 30 minutes after the knee injection at 0.10 units/kg actual body weight, rounded to the nearest whole unit, maximum 16 units. Doses are repeated approximately 24 and 48 hours later. For doses 2 and 3, predose glucose below 90 mg/dL requires withholding; 90 to 109 mg/dL requires 50% of the initial dose; 110 to 180 mg/dL requires 100%; 181 to 250 mg/dL requires 120%; and above 250 mg/dL requires 120%, maximum 20 units, plus clinician contact. Any glucose below 54 mg/dL or level 3 hypoglycaemia permanently discontinues study NPH.

  • Triamcinolone Acetonide Knee InjectionDrug

    Also called Triamcinolone Acetonide Crystalline Suspension

    A single 1 mL intra-articular injection of triamcinolone acetonide crystalline suspension 40 mg/mL, total dose 40 mg, will be administered into one index knee using a standardised landmark-guided procedure. Up to 2 mL lidocaine 1% without epinephrine may be used for skin and subcutaneous anaesthesia but will not be mixed with or injected into the joint. No repeat or additional injected corticosteroid is permitted through day 7.

Study groupRoleWhat they receive
Pre-emptive NPH Insulin PathwayExperimentalParticipants will receive three subcutaneous doses of human NPH insulin beginning within 30 minutes after intra-articular triamcinolone acetonide injection and repeated approximately 24 and 48 hours later. The initial dose is 0.10 units/kg, maximum 16 units. Subsequent doses are modified according to prespecified capillary-glucose and hypoglycaemia criteria. Participants will continue stable background diabetes medication and receive blinded continuous glucose monitoring, scheduled capillary glucose testing, safety contacts and the common rescue pathway.
Receives: Drug: Insulin Isophane Human, NPH, Pre-emptive Algorithm
Usual Reactive Diabetes ManagementActive comparatorParticipants will continue stable background diabetes medication without pre-emptive NPH insulin. They will receive blinded continuous glucose monitoring, the same scheduled capillary glucose testing, safety instructions, study contacts and common rescue pathway as the experimental group. Additional non-emergency medication changes may be made by the treating diabetes clinician when clinically necessary and will be documented.

What is being measured

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

  1. Percentage of Continuous Glucose Monitoring Time Above 180 mg/dL During the First 72 Hours After Corticosteroid Injection

    The numerator is the number of valid continuous glucose monitoring readings above 180 mg/dL from the recorded completion time of the intra-articular injection through exactly 72 hours. The denominator is the total number of valid readings during that window. The result is expressed as a percentage. A directly observed outcome requires at least 80% of expected readings and no uninterrupted data gap longer than 6 hours. Participants not meeting this requirement have a missing primary outcome for statistical handling; missing readings are not counted as being within or above range.

    Measured: From completion of the intra-articular corticosteroid injection through 72 hours after injection

Secondary outcomes (12)
  1. Percentage of Continuous Glucose Monitoring Time Above 250 mg/dL

    Number of valid continuous glucose monitoring readings above 250 mg/dL divided by all valid readings, multiplied by 100. The primary-outcome valid-data requirements apply.

    Measured: From completion of the injection through 72 hours after injection

  2. Continuous Glucose Monitoring Area Under the Curve Above 180 mg/dL

    Incremental area above 180 mg/dL calculated using the trapezoidal rule across adjacent valid readings separated by no more than 30 minutes. The observed mean excess above 180 mg/dL is standardised to a 72-hour period and reported in mg/dL-hours.

    Measured: From completion of the injection through 72 hours after injection

  3. Mean Sensor Glucose

    Arithmetic mean of all valid continuous glucose monitoring readings during the assessment window, reported in mg/dL.

    Measured: From completion of the injection through 72 hours after injection

  4. Peak Sensor Glucose

    Highest valid continuous glucose monitoring glucose value during the assessment window, reported in mg/dL.

    Measured: From completion of the injection through 72 hours after injection

  5. Time to Peak Sensor Glucose

    Elapsed time in hours from completion of the injection to the first occurrence of the participant's peak valid sensor glucose.

    Measured: From completion of the injection through 72 hours after injection

  6. Percentage of Continuous Glucose Monitoring Time in Range, 70 to 180 mg/dL

    Number of valid continuous glucose monitoring readings from 70 through 180 mg/dL divided by all valid readings, multiplied by 100.

    Measured: From completion of the injection through 72 hours after injection

  7. Percentage of Continuous Glucose Monitoring Time Below 70 mg/dL

    Number of valid continuous glucose monitoring readings below 70 mg/dL divided by all valid readings, multiplied by 100.

    Measured: From completion of the injection through 72 hours after injection

  8. Percentage of Continuous Glucose Monitoring Time Below 54 mg/dL

    Number of valid continuous glucose monitoring readings below 54 mg/dL divided by all valid readings, multiplied by 100.

    Measured: From completion of the injection through 72 hours after injection

  9. Participants With Clinically Significant Hypoglycaemia

    Number and percentage of participants with capillary glucose below 54 mg/dL, continuous glucose monitoring glucose below 54 mg/dL lasting at least 15 consecutive minutes, or level 3 hypoglycaemia requiring third-party assistance.

    Measured: From completion of the injection through day 7

  10. Participants Requiring Rescue Glucose-Lowering Treatment

    Number and percentage of participants receiving protocol rescue insulin or any additional glucose-lowering medication initiated for post-injection hyperglycaemia.

    Measured: From completion of the injection through 72 hours after injection

  11. Number of Unscheduled Diabetes-Related Clinical Contacts or Healthcare Encounters

    Count per participant of unscheduled telephone calls, electronic contacts, clinic visits, urgent-care visits or emergency-department encounters primarily related to glucose management.

    Measured: From completion of the injection through day 7

  12. Participant-Reported Treatment Burden Score

    Study-specific numerical rating from 0 to 10, where 0 means no treatment burden and 10 means extreme treatment burden.

    Measured: Day 4

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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Percentage of Continuous Glucose Monitoring Time Above 180 mg/dL During the First 72 Hours After Corticosteroid Injection (time frame: From completion of the intra-articular corticosteroid injection through 72 hours after injection). 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 15 Sep 2026.
