Trial Title: A French Study to Evaluate the Usefulness of an Implantable Continuous Glucose Monitoring (CGM) Sensor to Improve Glycemic Control in Participants With Diabetes Mellitus

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: DIAGNOSTIC
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 4.0

Eligibility Criteria:
Inclusion Criteria:~* Male and female participants at least 18 years of age~* Clinically confirmed diagnosis of Type 1 or Type 2 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and an HbA1c \> 8% (Cohort 1)~* Clinically confirmed diagnosis of Type 1 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and spending more than more than 1.5 hour with sensor glucose \<70 mg/dl per day including excursions below 54 mg/dl as a mean for at least 28 days (Cohort 2)~* Participant is willing to comply with protocol~Exclusion Criteria:~* Female participants of childbearing capacity (defined as not surgically sterile or not menopausal for ≥ 1 year) who are lactating or pregnant, intending to become pregnant, or not practicing birth control during the course of the study~* A condition preventing or complicating the placement, operation or removal of the Sensor or wearing of transmitter, including upper extremity deformities or skin condition~* History of hepatitis B, hepatitis C, or HIV~* Currently receiving (or likely to need during the study period): immunosuppressant therapy; chemotherapy; anticoagulant/antithrombotic therapy (excluding aspirin \< 2000 mg per day); antibiotics for chronic infection (e.g. osteomyelitis, endocarditis)~* A condition requiring or likely to require magnetic resonance imaging (MRI)~* Known topical or local anesthetic allergy~* Known allergy to glucocorticoids or using systemic glucocorticoids (excluding topical, optical or nasal but including inhaled)~* Any condition that in the investigator's opinion would make the participant unable to complete the study or would make it not in the participant's best interest to participate in the study. Conditions include, but are not limited to, psychiatric conditions, known current or recent alcohol abuse or drug abuse by participant history, a condition that may increase the risk of induced hypoglycemia or risk related to repeated blood testing. Investigator will supply rationale for exclusion~* Participation in another clinical investigation (drug or device) within 2 weeks prior to screening or intent to participate during the study period~* Legal incompetence or limited legal competence~* Dependency on sponsor or Investigator (e.g. co-worker or family member)~* The presence of any other active implanted device

Study Arms:
- Cohort 1, Enabled - Eversense XL CGM System (Type: EXPERIMENTAL): Cohort 1 included patients with clinically confirmed diagnosis of Type 1 or Type 2 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and had an HbA1c \>8%. All participants had the Eversense XL Glucose Sensor subcutaneously implanted into their arm of choice. Those randomized into the Enabled group were trained and allowed to use the Eversense XL system for continuous glucose monitoring (CGM). They were not allowed to use another CGM or FGM system.
- Cohort 1, Control - Usual Glucose Monitoring System (SMBG or FGM) (Type: ACTIVE_COMPARATOR): Cohort 1 included patients with clinically confirmed diagnosis of Type 1 or Type 2 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and had an HbA1c \>8%. All participants had the Eversense XL Glucose Sensor subcutaneously implanted into their arm of choice. Those randomized into the Control group were to continue using their usual glucose monitoring system (self-monitoring of blood glucose \[SMBG\] or flash glucose monitoring \[FGM\]), and the implanted Eversense XL CGM System remained in blinded mode.
- Cohort 2, Enabled - Eversense XL CGM System (Type: EXPERIMENTAL): Cohort 2 included patients with Type 1 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and spending \>1.5 hours per day with a sensor mean glucose of \<70 mg/dL for at least 28 days (time in hypoglycemia). All participants had the Eversense XL Glucose Sensor subcutaneously implanted into their arm of choice. Those randomized into the Enabled group were trained and allowed to use the Eversense XL system for continuous glucose monitoring (CGM). They were not allowed to use another CGM or FGM system.
- Cohort 2, Control - Usual Glucose Monitoring System (SMBG or FGM) (Type: ACTIVE_COMPARATOR): Cohort 2 included patients with Type 1 diabetes mellitus for ≥1 year and using insulin by multiple-daily subcutaneous injections or insulin pump and spending \>1.5 hours per day with a sensor mean glucose of \<70 mg/dL for at least 28 days (time in hypoglycemia). All participants had the Eversense XL Glucose Sensor subcutaneously implanted into their arm of choice. Those randomized into the Control group were to continue using their usual glucose monitoring system (self-monitoring of blood glucose \[SMBG\] or flash glucose monitoring \[FGM\]), and the implanted Eversense XL CGM System remained in blinded mode.
