Efficacy and safety of once-weekly glucagon-like peptide 1 receptor agonist albiglutide (HARMONY 1 trial): 52-week primary endpoint results from a randomized, double-blind, placebo-controlled trial in patients with type 2 diabetes mellitus not controlled on pioglitazone, with or without metformin.

AIMS: To show that albiglutide, a glucagon-like peptide-1 receptor agonist, is an effective and generally safe treatment to improve glycaemic control in patients with type 2 diabetes mellitus whose hyperglycaemia is inadequately controlled with pioglitazone (with or without metformin). METHODS: In this 3-year, randomized, double-blind, placebo-controlled study, 310 adult patients on a regimen of pioglitazone (with or without metformin) were randomly assigned to receive additional treatment with albiglutide [30 mg subcutaneous (s.c.) once weekly, n = 155] or matching placebo (n = 155). The primary efficacy endpoint was change from baseline to week 52 (intention-to-treat) in glycated haemoglobin (HbA1c). RESULTS: The model-adjusted change from baseline in HbA1c at week 52 was significantly better with albiglutide than with placebo (-0.8%, 95% confidence interval -1.0, -0.6; p < 0.0001). Change from baseline fasting plasma glucose was -1.3 mmol/l in the albiglutide group and +0.4 mmol/l in the placebo group (p < 0.0001); a significantly higher percentage of patients reached the HbA1c goals with albiglutide (p < 0.0001), and the rate of hyperglycaemia rescue up to week 52 for albiglutide was 24.4 versus 47.7% for placebo (p < 0.0001). Albiglutide plus pioglitazone had no impact on weight, and severe hypoglycaemia was observed rarely (n = 2). With few exceptions, the results of safety assessments were similar between the groups, and most adverse events (AEs) were mild or moderate. The 52-week incidence rates for gastrointestinal AEs for albiglutide and placebo were: 31.3 and 29.8%, respectively (diarrhoea: 11.3 and 8.6%; nausea: 10.7 and 11.3%; vomiting: 4.0 and 4.0%). CONCLUSIONS: Albiglutide 30 mg administered once weekly as an add-on to pioglitazone (with or without metformin) provided effective and durable glucose lowering and was generally well tolerated.

Low-dose oral fluorouracil with eniluracil as first-line chemotherapy against advanced breast cancer: a phase II study.

PURPOSE: Eniluracil (776C85) is an effective inactivator of dihydropyrimidine dehydrogenase that allows continuous low-dose oral fluorouracil (5-FU) to be given with predicable oral bioavailability. We have assessed this as first-line oral chemotherapy for patients with advanced/metastatic breast cancer. PATIENTS AND METHODS: Patients with histologically proven, locally advanced or metastatic breast cancer without previous chemotherapy for advanced disease were entered onto this open-label phase II study. Patients received oral 5-FU 1.0 mg/m(2) with eniluracil 10 mg/m(2), both given twice daily for the first 28 days of each 35-day cycle, continuing until disease progression or unmanageable toxicity. RESULTS: Thirty-three patients were entered, with a median age of 53 years. Sixteen partial responses were seen in twenty-nine assessable patients (55%; 95% confidence interval, 37% to 73%), including responses in four (40%) out of 10 patients who had received prior adjuvant 5-FU. Seven patients had stable disease for at least 3 months with symptom improvement. Median response duration was 14 months (range, 10 to 18+ months). Toxicity was low. There were only two episodes of drug-related grade 3 nonhematologic toxicity (diarrhea and infection), and only 6%, 3%, and 3% of patients developed granulocytopenia, thrombocytopenia, and neutropenic sepsis, respectively. Mild (grade 1/2) diarrhea occurred in 39% of patients, hand-foot syndrome in 15%, nausea in 27%, and mucositis in 18%. Toxicity-associated delay and dose reduction occurred in only 2% and 5% of courses, respectively. CONCLUSION: First-line treatment with the combination of oral 5-FU and eniluracil has high activity in patients with advanced breast cancer comparable with the most active conventional cytotoxic agents but with strikingly less toxicity.

Effect of metformin plus roziglitazone compared with metformin alone on glycaemic control in well-controlled Type 2 diabetes.

AIMS: To investigate the effect of metformin plus roziglitazione (RSGMET) compared with metformin alone (MET) on glycaemic control in well-controlled Type 2 diabetes. METHODS: Subjects (drug naïve or those on glucose-lowering monotherapy) were randomized (n = 526), following a 4-week placebo run-in period, to RSGMET [4 mg rosiglitazone (RSG)/500 mg MET] or MET 500 mg. From weeks 2-18, medication was escalated every 4 weeks (based on gastrointestinal tolerability), then remained at RSGMET 8 mg/2 g or MET 3 g for 14 weeks. RESULTS: RSGMET reduced HbA(1c) from 7.2 +/- 0.6 to 6.7 +/- 0.8% at week 32, compared with a reduction from 7.2 +/- 0.6 to 6.8 +/- 0.9% with MET (treatment difference -0.13%; P = 0.0357). More subjects achieved an HbA(1c) value of

A phase II study of oral eniluracil/fluorouracil in patients with anthracycline-refractory or anthracycline- and taxane-refractory advanced breast cancer.

BACKGROUND: Eniluracil is an effective inactivator of dihydropyrimidine dehydrogenase, the initial and rate limiting enzyme in the catabolism of fluorouracil. The current study was done to determine the objective tumour response of a 28-day oral regimen of eniluracil-fluorouracil in patients with advanced breast cancer. PATIENTS AND METHODS: This was a multicentre, phase II study in patients with anthracycline-refractory (AR) or anthracycline- and taxane-refractory (ATR) advanced breast cancer. Oral eniluracil (10 mg/m2) and fluorouracil (1 mg/m2) were taken twice daily for 28 days of each 35-day treatment course. RESULTS: In this study, 106 patients received treatment: 62 patients in the AR stratum and 44 patients in the ATR stratum. The objective tumour response rate in the intent-to-treat population was 18% (95% confidence intervals (CI): 11%-27%), including three complete responses. The response rate was similar in both strata: 19% in the AR and 16% in the ATR stratum. The overall median duration of response was 23.6 weeks. The treatment was well tolerated with a low incidence of grade 3 or 4 toxicities that were considered attributable to study medication. CONCLUSION: Treatment with oral eniluracil-fluorouracil was well tolerated by patients with advanced breast cancer. The efficacy data were comparable with those of other published studies in this group of refractory patients.
