Inclusion Criteria:
- The participant is willing and able to give informed consent to participate in the study.
- The participant is at least 18 years of age at the time of enrolment.
- The participant has a clinical diagnosis of Type 1 diabetes, with 7% < HbA1C < 10% within the last 6 months, for a minimum of 6 months duration prior to enrolment, as determined by a medical record by an individual qualified to make a medical diagnosis, and is using insulin (either by an insulin pump, subcutaneous injections, and/or inhaled insulin) for at least 6 months prior to enrolment.
- If participant is using noninsulin glucose-lowering medications (such as SGLT2I Inhibitor, Metformin, or other), dose has been stable for at least 2 weeks prior to screening.
- The participant body weight is at least 110 pounds, in accordance with U.S. Department of Health and Human Services guidance for blood collection.
- The participant has adequate venous access as assessed by an investigator or appropriate centre staff.
- The participant is available to attend all three up to 8-hour, clinically supervised, in-clinic sessions and to have multiple venous and capillary blood samples collected.
- The participant agrees to not consume Vitamin C for the duration of the study.
- The participant is prepared to record details related to their participation (e.g. meals, finger prick times, device incidents, comfort) daily.
- The participant is prepared to wear up to three blinded investigational devices, and one unblinded investigational device for 15 days.
- In the investigators' opinion, are suitable for participation in the study.
- The participant is able to read and understand English.
- The participant is willing to return the research devices at the end of the study.
- The participant is willing to manage diabetes with insulin during study visits as they would do otherwise.
- The participant can commit to not getting the CGMs wet for the first 12 hours after application, such as by showering or swimming.
Exclusion Criteria:
- The participant gave birth within the last 6 months, is pregnant, is trying to conceive or is not willing and able to practice birth control during the study duration.
- The participant has serious concomitant disorders or diseases (e.g. history of hypoglycaemia with unawareness requiring third party assistance, coagulation disorders) that would compromise the safety of the participant or their ability to complete the study, at the discretion of the Investigator.
- The participant has had a recent cardiovascular event or major surgery in the last 6 months that would compromise the safety of the participant or their ability to complete the study, at the discretion of the Investigator.
- The participant has been admitted to the hospital with Diabetic Ketoacidosis in the last 6 months prior to enrolment.
- The participant has donated more than 500mL of blood in the past 4 weeks.
- The participant has a blood haemoglobin (Hb) that is 10% or more below the normal reference range for men and women, at the discretion of the Investigator.
- Current use of sulfonylurea medications.
- Current use of GLP-1 Receptor Agonist medications.
- The participant has an implanted medical device such as a pacemaker or an implantable cardioverter-defibrillator (ICD).
- The participant has multiple tattoos, scars, active skin condition or wound, or significant dermatitis overlying the skin where devices are likely to be placed.
- The participant has a known allergy or sensitivity to skin adhesives or sensor materials.
- The participant is taking part in another interventional clinical study requiring blood sampling, an investigational drug or device during the 15-day wear period of this study.
- The participant is not willing to suspend their hybrid closed loop (Automated Insulin Delivery) system during the clinic sampling session.
- The participant has any X-ray or MRI scheduled at any time during the participation of the study.
- Any other reason which, in the investigator's opinion, would compromise participant safety or data integrity.

Paired Sensor-Venous Blood Glucose Readings
Tijdsspanne: For the duration of time the participant is wearing the CGM device (Day 0 to Day 14; up to 15 days)
|
The primary outcome is at least 98% of all paired sensor-venous blood glucose reference readings fall within the clinically acceptable Zones A and B of the Clarke Error Grid.
|
For the duration of time the participant is wearing the CGM device (Day 0 to Day 14; up to 15 days)

Assessment of comfort associated with devices at insertion and removal
Tijdsspanne: At device application (Day 0) and removal (up to Day 14)
|
Assess participant-reported comfort and pain associated with sensor application and removal using the Numeric Pain Rating Scale which measures participants' pain level on a scale of 0 to 10 where higher scores mean worse pain.
|
At device application (Day 0) and removal (up to Day 14)
|
|
Assessment of duration of pain associated with devices at insertion and removal
Tijdsspanne: At device application (Day 0) and removal (up to Day 14)
|
Assess participant-reported comfort and pain associated with sensor application and removal using the Pain Duration Scale which measures participants' pain level at different time points (within 5 seconds, 5-30 seconds, more than 30 seconds) after sensor application or removal, on a scale of 0 to 10 where higher scores mean worse pain.
|
At device application (Day 0) and removal (up to Day 14)
|
|
Evaluation of skin response at device wear sites
Tijdsspanne: At device application (Day 0) and removal (up to Day 14)
|
Characterise the skin and evaluate skin response at sensor wear sites before and after device removal using the Draize Scale where higher scores mean worse skin response.
|
At device application (Day 0) and removal (up to Day 14)
|
|
Characterisation of the safety profile of the SAVA CGMs
Tijdsspanne: Up to 15 days (Day 14)
|
Characterise the safety profile of the SAVA CGM in terms of adverse events and device deficiencies.
The number, type, and severity of adverse events and device deficiencies will be evaluated.
|
Up to 15 days (Day 14)
|
|
Description of SAVA CGM clinical safety profile
Tijdsspanne: Up to 15 days (Day 14)
|
Describe the clinical safety profile of the SAVA CGM based on the percentage distribution of paired sensor-reference glucose readings across zones of the Consensus (Parkes) Error Grid.
|
Up to 15 days (Day 14)
