Efficacy and Safety of Soliqua Versus Lantus in Ethnically/Racially Diverse Patients With Type 2 Diabetes Mellitus Inadequately Controlled on Basal Insulin and Oral Antidiabetic Agents

Inclusion criteria : * Participants with type 2 diabetes mellitus (T2DM) diagnosed at least 1 year prior to the screening visit (signing of informed consent). * Uncontrolled diabetes as demonstrated by a screening centrally measured hemoglobin A1c (HbA1c) between 7.5% and 10% (inclusive). * Participants who were Hispanics of any race, non-Hispanic black/African Americans or non-Hispanic Asians. Note: Decision for ethnic/racial inclusion was made based on the participant's self-identification. Mixed-race participants must select 1 of the above-mentioned categories. If such selection could not be made, the candidate would be ineligible to participate in the study. * Participants who had been treated with any basal insulin (ie, glargine - U100 or U300, detemir, degludec, intermediate-acting \[human Neutral Protamine Hagedorn (NPH\]) for at least 6 months prior to Visit 1. * The basal insulin regimen (ie, type of insulin and time/frequency of the injection) had been stable for at least 3 months prior to Visit 1. * The basal insulin dose had been stable (defined as up to ±20% \[1/5 of the dose\] variability) for at least 2 months prior to Visit 1 within the following dose ranges: * 15 to 50 units/day if HbA1c at Visit 1 is less than or equal to (\<=)8.5%, and * 15 to 40 units/day if HbA1c at Visit 1 is greater than (\>)8.5%. * Participants receiving 1 or 2 of the following OAD drugs: metformin, pioglitazone/rosiglitazone, an sodium-glucose transport protein 2 (SGLT-2) inhibitor or a sulfonylurea (SU), at stable doses for at least 12 weeks prior to Visit 1. Exclusion criteria: * Age \<18 years of age at Visit 1. * A body mass index (BMI) \<=20 or \>40 kg/m\^2 at Visit 1. * Fasting plasma glucose (FPG) \>200 mg/dL (by central lab measurement) at Visit 1 (1-time repeat measurement before Visit 2 is permitted). * Type 1 DM or any diabetes other than T2DM. * Any use of OAD drugs other than those described in the inclusion criteria (e.g., but not limited to, glucagon like peptide-1 receptor agonist (GLP-1 RA), dipeptidyl peptidase 4 (DPP4) inhibitors) within 12 weeks prior Visit 1. * Use of any other type of insulin except for basal insulin (e.g., prandial or premixed insulin, insulin pump) within 6 months prior to Visit 1. Note: History of short-term treatment (i.e, \<=10 days) with other insulin types due to intercurrent illness was permitted at the discretion of the Investigator. * Known history of discontinuation of treatment with a GLP-1 RA due to safety/tolerability reasons. * Use of systemic glucocorticoids for a total duration of \>7 days within 12 weeks prior to Visit 1. * Initiation/change in type or dose of a weight loss drug within 12 weeks prior to Visit 1.
