The present invention relates to oral pharmaceutical formulations comprising a compound of Formula I or a pharmaceutically acceptable salt thereof
wherein R, A and n are as described herein. The present invention also relates to processes for their preparation and their use in treating disorders such as cardiovascular and metabolic disorders, including diabetes.
Approximately 415 million people live with diabetes worldwide, and an estimated 193 million people have undiagnosed diabetes. Type-2 diabetes accounts for more than 90% of patients with diabetes and leads to microvascular and macrovascular complications that cause profound psychological and physical distress to both patients and carers and put a huge burden on health-care systems. Type-2 diabetes mellitus is a chronic metabolic condition characterised by chronic hyperglycemia due to deficiency in the secretion and/or function of insulin (i.e. insulin resistance). Type-2 diabetes mellitus is known to be associated with a reduced life expectancy and increased morbidity. Although cardiovascular disease is the commonest cause of mortality and morbidity, Type-2 diabetes mellitus is also associated with an increased risk of other diseases including cancer, chronic liver disease including non-alcoholic fatty liver disease (NAFLD) such as non-alcoholic fatty liver (NAFL), non-alcoholic steatohepatitis (NASH), dyslipidaemias, and related disorders, cognitive decline and accelerated arthritis, in addition to the microvascular and macrovascular complications.
After long duration of disease, most patients with Type-2 diabetes will eventually fail on oral therapy and become insulin dependent with the necessity for daily injections and multiple daily glucose measurements. Oral antidiabetic drugs conventionally used in therapy (such as e.g. first- or second-line, and/or mono- or (initial or add-on) combination therapy) include, for example, metformin, sulphonylureas, thiazolidinones, glinides, and α-glucosidase inhibitors.
The high incidence of therapeutic failure is a major contributor to the high rate of long-term hyperglycaemia-associated complications or chronic damages (including micro- and macrovascular complications such as e.g. diabetic nephropathy, retinopathy or neuropathy, or cardiovascular complications) in patients with Type-2 diabetes.
U.S. Pat. No. 10,208,030 describes GPR119 agonists and processes for their preparation.

Required amounts of the Compound of Formula IA and (2-hydroxylpropyl) beta-cyclodextrin (HPPCD) were weighed.
Sterile water for injection was added to the (2-hydroxylpropyl) beta-cyclodextrin to obtain a 5% solution w/v. Half the volume of the 5% HPPCD solution was added to the Compound of Formula I with mixing. The resulting material was sonicated for 15 minutes. The remaining half volume of the 5% HPPCD solution was then added and the resulting suspension sonicated for a further 15 minutes
The suspension prepared in Step 2 was then stirred at 900-1200 RPM for 60 minutes to afford a white to off-white suspension.
Maintain a temperature of 20-25° C. during all process steps.
Store final suspension at 20-25° C. for not more than 24 hours.
