Fixed-Dose Combination of Dapagliflozin + Sitagliptin + Metformin in Patients with Type 2 Diabetes Poorly Controlled with Metformin: Phase 3, Randomized Comparison with Dual Combinations.

INTRODUCTION: This study compared efficacy and safety of triple drug fixed-dose combination (FDC) of dapagliflozin (DAPA) + sitagliptin (SITA) + metformin (MET) extended release (ER) with SITA + MET sustained release (SR) and DAPA + MET ER in patients with type 2 diabetes poorly controlled with metformin. METHODS: This phase 3, randomized, open-label, active-controlled study included adult patients with glycated hemoglobin (HbA1c) ≥ 8% (64 mmol/mol) and ≤ 11% (97 mmol/mol), randomized in 1:1:1 ratio to receive either FDC of DAPA + SITA + MET ER (10 mg + 100 mg + 1000 mg) tablets once daily (n = 137) or co-administration of SITA + MET SR (100 mg + 1000 mg) tablets once daily (n = 139) or FDC of DAPA + MET ER (10 mg + 1000 mg) tablets once daily (n = 139). Primary endpoint was mean change in HbA1c from baseline to week 16. RESULTS: Mean baseline HbA1c was approximately 9% (75 mmol/mol) in each treatment group. At week 16, adjusted mean reduction in HbA1c from baseline was significantly greater with DAPA + SITA + MET ER (- 1.73% [- 19.0 mmol/mol]) compared to SITA + MET SR (- 1.28% [- 14.1 mmol/mol]; difference of - 0.46% [- 5.1 mmol/mol], p < 0.001) and DAPA + MET ER (- 1.33% [- 14.6 mmol/mol]; difference - 0.4% [4.4 mmol/mol], p < 0.001). Similarly, at week 12, reduction in HbA1c from baseline was significantly greater with DAPA + SITA + MET ER compared to SITA + MET SR (p = 0.0006) and DAPA + MET ER (p = 0.0276). At week 16, DAPA + SITA + MET ER showed significant reduction in postprandial blood glucose compared to DAPA + MET ER (p = 0.0394) and significant reduction in fasting blood glucose with DAPA + SITA + MET ER compared to SITA + MET SR (p = 0.0226). The proportion of patients achieving HbA1c < 7.0% (53 mmol/mol) at week 16 was significantly higher with DAPA + SITA + MET ER (38.5%) versus SITA + MET SR (12.8%) (p < 0.001) and DAPA + MET ER (21.3%) (p = 0.0023). All study medications were well tolerated. CONCLUSION: Triple FDC of DAPA + SITA + MET ER tablets once daily was significantly better in achieving glycemic control versus dual combination once daily in patients with type 2 diabetes poorly controlled with metformin without any significant safety concerns.

Type 2 diabetes is a progressive disease in which the risks of microvascular and macrovascular complications and mortality are strongly associated with hyperglycemia. Achieving glycemic control remains the main goal of treatment to prevent these complications. Estimates in 2019 showed that 77 million individuals had diabetes in India, which is expected to rise over 134 million by 2045. Considering the progressive nature of the disease, many guidelines recommend use of dual or triple drug therapy based on glycated hemoglobin (HbA1c) level. Use of fixed-dose combination (FDC) helps to improve therapy compliance and can provide optimum therapeutic benefits. Mechanisms of action of dipeptidyl peptidase 4 (DPP4) and sodium­glucose cotransporter 2 (SGLT2) inhibitors are complementary to that of metformin with low risk of hypoglycemia. Studies have shown beneficial effects of adding both DPP4 inhibitors and SGLT2 inhibitors after metformin monotherapy. This phase 3 study was designed to assess efficacy and safety of triple FDC of dapagliflozin + sitagliptin + metformin extended release in comparison with combipack of sitagliptin + metformin sustained release and FDC of dapagliflozin + metformin ER in patients with type 2 diabetes inadequately controlled with metformin monotherapy. The study demonstrated superiority of triple FDC of dapagliflozin + sitagliptin + metformin ER over dual combinations in terms of reduction in HbA1c and percentage of patients achieving target HbA1c at the end of week 16. The current study provides evidence for considering triple FDC of dapagliflozin + sitagliptin + metformin ER as an alternative option with minimal risk of hypoglycemia and weight gain, while considering oral triple-combination therapy for patients to achieve their glycemic target.

One-year safety and effectiveness of insulin degludec in patients with diabetes mellitus in routine clinical practice in India-TRUST (Tresiba real-world use study).

Objective: This post-authorization safety study (PASS) was conducted to evaluate the long-term safety and effectiveness of insulin degludec in patients with diabetes mellitus (DM) requiring insulin therapy in routine clinical practice in India. Methods: Data on glycated hemoglobin (HbA1c) and adverse events (AEs) were collected up to 12 months after insulin degludec initiation. Results: A total of 1057 adult patients with DM were enrolled, including 60.07% males with the mean duration of 22.2 ± 21.90 years with type 1 DM and 10.1 ± 7.37 years with type 2 DM and the mean HbA1c of 9.6 ± 1.9%. Insulin degludec was prescribed to improve HbA1c and fasting plasma glucose (FPG). Insulin degludec daily dose was increased from 14.8 ± 8.0 U to 18.0 ± 9.46 U over 12 months resulting in a significant decrease of HbA1c by 1.8 ± 1.68% compared with baseline. There were 84 events of confirmed hypoglycemia in 51 patients during the 12-month follow-up period, and 44 AEs were reported in 2.6% of patients, of which 2 AEs were serious and unrelated to the drug. Conclusion: Insulin degludec is well tolerated in patients with DM. It improves glycemic control with reduced HbA1c, FPG, and postprandial glucose, with a low risk of hypoglycemia.

Blood-pressure Lowering Efficacy and Safety of Perindopril / Indapamide / Amlodipine Single-pill Combination in Hypertensive Patients: Phase III Trial in India.

BACKGROUND: Hypertension is the biggest contributor to global burden of disease and mortality. Increasing compliance with antihypertensive treatment and achieving a wide BP control in the population represents a major challenge for clinical practice. The benefits of single pill combination versus free-equivalent combination has been demonstrated in several meta-analyses and is now strongly supported by the latest 2018 ESC/ESH guidelines. The RAAS blocker with CCB and thiazide like diuretic is proposed as the optimal combination in patients inadequately controlled by two drugs. OBJECTIVE: To assess the blood pressure control rate, safety, tolerability and quality of life with triple-drug SPC in patients with grade II/ III hypertension. METHODS: Hypertensive patients uncontrolled (BP ≥ 140/90 mmHg) on two-drug therapy were recruited in an open-label, phase III clinical trial conducted in outpatient setting in India with 6 months treatment period. No other antihypertensive medication except the study medication was received by the patients. RESULTS: Out of 218 evaluable patients the observed average blood pressure reduction achieved from baseline to end of study at 6 months was Systolic Blood Pressure (SBP) 28.5 mm Hg / Diastolic Blood Pressure (DBP) 13.8 mm Hg. The quality of life (QoL) questionnaire demonstrated improvement in QoL for all patients. CONCLUSION: This study showed the clinical efficacy, safety and acceptability of the perindopril/indapamide/amlodipine SPC in patients with grade 2/3 hypertension inadequately controlled with two-drug therapy. The clinical effectiveness was observed in more than 96 % patients. The benefit of single-pill combination (SPC) therapy in hypertension control was reconfirmed in this study.
