Intensive therapy in newly diagnosed type 2 diabetes: results of a 6-year randomized trial.

ABSTRACT: This study aimed to assess the efficacy of early intensive diabetes therapy with either insulin plus metformin (INS) or triple oral therapy (TOT) with metformin, glyburide, and pioglitazone on glycemic control and A-cell function.Fifty-eight treatment-naive newly diagnosed patients with type 2 diabetes underwent a 3-month lead-in treatment period with insulin and metformin, then were randomized to INS or TOT for 6 years. ?-Cell function was measured using mixed-meal challenge test. ?-Cell function remained stable throughout the 6-year study in both groups, as measured by the C-peptide area under the curve (AUC; P = 0.13), the AUC C-peptide/AUC glucose (P = 0.9), and by the disposition index (P = 0.8). Excellent glycemic control was maintained in both groups (end-of-study hemoglobinA1c, 7.3% [SD, 1.7%] INS vs 6.4% [1.4%] TOT; P = 0.4). There were 8 treatment failures (confirmed hemoglobinA1c, 98%) in INS and 6 in TOT (P = 0.93). The predictors of treatment failure included higher fasting glucose (P = 0.008), fasting C-peptide (P = 0.008), systolic blood pressure (P = 0.004), and lower insulin sensitivity (P = 0.04) at randomization.Early intensive treatment at the time of type 2 diabetes diagnosis-initial short-term insulin treatment followed by either insulin-based or intensive oral hypoglycemic-based therapy-stabilizes ?-cell function for at least 6 years. Treatment failure was independent of intervention and was associated with worse disease pathology at baseline.

Project description:OBJECTIVE:To assess the efficacy and safety of short- term intensive hypoglycemic therapy with a triple regimen consisting of metformin, sagliptin and dapagliflozin in patients with newly diagnosed type 2 diabetes mellitus with hemoglobin Alc (HbA1c) of 9%-12%. METHODS:We prospectively enrolled 58 patients with newly diagnosed type 2 diabetes, who were treated with metformin combined with sagliptin and dapagliflozin for 12 weeks on the basis of diabetic diet and regular exercise. Blood glucose was monitored during the treatment and the changes in HbA1c, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2 hPBG), fasting insulin (FINS), 2-hour postprandial insulin (2 hPINS), fasting C-peptide (F-CP), 2-hour postprandial C-peptide (2 hP-CP), and body weight after treatment as well as the incidence of hypoglycemia and adverse events associated with the treatment were recorded. RESULTS:Two patients withdrew from the study for intolerance of gastrointestinal reactions, and another 2 withdrew for inconvenience of access to the medicines. Fifty-four of the patients finally completed the study, including 34 male and 20 female patients. After 12 weeks of therapy, all the patients showed significant improvements in FBG, 2 hPBG, HbA1c, HOMA-beta and HOMA-IR (P < 0.001) with a mean reduction of HbA1c level by (4.19 ± 1.07)%, and the goal of HbA1c control to below 7.0% was achieved in 83.33% of the patients. The reduction of HbA1c was correlated with FBG (r=0.487, P=0.000), 2 hPBG (r=0.310, P=0.023), and HOMA-? (r=-0.398, P=0.003). The patients had a mean body weight loss by 2.47±3.38 kg (P < 0.001) and a mean decrease of body mass index (BMI) by 0.90± 1.18 kg/m2 (P < 0.001) after the therapy. The body weight-reducing effect was associated with the patients' baseline body weight (r=0.678, P=0.000), BMI (r=0.818, P=0.000), F-CP (r=0.282, P=0.039) and HOMA-IR (r=0.297, P=0.029). During the therapy 8 patients experienced hypoglycemic symptoms (10 times, 14.81%); 3 patients were diagnosed with hypoglycemia (blood glucose ?3.9 mmol/L, 3 times), and the overall incidence of hypoglycemia was 5.56%. No serious hypoglycemia or infections of the urinary and reproductive systems occurred in these patients. CONCLUSIONS:Short-term intensive oral hypoglycemic therapy with metformin combined with sagliptin and dapagliflozin is effective for treatment of patients with newly diagnosed type 2 diabetes with HbA1c of 9%-12% and shows a good weight-reducing effect with a low risk of hypoglycemia. The combined therapy can effectively improve ?-cell insulin secretion function, and is suitable for treatment of newly diagnosed type 2 diabetic patients with high blood glucose.

Project description:Purpose Bosutinib is a potent dual SRC/ABL kinase inhibitor approved for adults with Philadelphia chromosome-positive chronic myeloid leukemia (CML) resistant and /or intolerant to prior therapy. We assessed the efficacy and safety of bosutinib versus imatinib for first-line treatment of chronic-phase CML. Methods In this ongoing, multinational, phase III study, 536 patients with newly diagnosed chronic-phase CML were randomly assigned 1:1 to receive 400 mg of bosutinib once daily (n = 268) or imatinib (n = 268). Per protocol, efficacy was assessed in patients who were Philadelphia chromosome-positive with typical (e13a2/e14a2) transcripts (bosutinib, n = 246; imatinib, n = 241). Patients with Philadelphia chromosome-negative-/ BCR-ABL1-positive status and those with unknown Philadelphia chromosome status and/or atypical BCR-ABL1 transcript type were excluded from this population. Results The major molecular response (MMR) rate at 12 months (primary end point) was significantly higher with bosutinib versus imatinib (47.2% v 36.9%, respectively; P = .02), as was complete cytogenetic response (CCyR) rate by 12 months (77.2% v 66.4%, respectively; P = .0075). Cumulative incidence was favorable with bosutinib (MMR: hazard ratio, 1.34; P = .0173; CCyR: hazard ratio, 1.38; P < .001), with earlier response times. Four patients (1.6%) receiving bosutinib and six patients (2.5%) receiving imatinib experienced disease progression to accelerated/blast phase. Among treated patients, 22.0% of patients receiving bosutinib and 26.8% of patients receiving imatinib discontinued treatment, most commonly for drug-related toxicity (12.7% and 8.7%, respectively). Grade ≥ 3 diarrhea (7.8% v 0.8%) and increased ALT (19.0% v 1.5%) and AST (9.7% v 1.9%) levels were more common with bosutinib. Cardiac and vascular toxicities were uncommon. Conclusion Patients who received bosutinib had significantly higher rates of MMR and CCyR and achieved responses faster than those who received imatinib. Consistent with the known safety profile, GI events and transaminase elevations were more common with bosutinib. Results indicate bosutinib may be an effective first-line treatment for chronic-phase CML.
