Alendronate/colecalciferol 70 mg/2800 IU, a once-weekly tablet containing the bisphosphonate alendronate and colecalciferol (the precursor of the biologically active form of vitamin D), has been approved for the treatment of osteoporosis in women and for increasing bone mass in men with osteoporosis. The mean oral bioavailability of alendronate or colecalciferol is similar when administered alone or as one once-weekly tablet containing alendronate/colecalciferol 70 mg/2800 IU. In a 15-week, randomized, double-blind, multicenter study in patients with osteoporosis, the proportion of patients with serum 25-hydroxyvitamin D3 levels <15 ng/mL was significantly lower with alendronate/colecalciferol than with alendronate alone.

Patients with early Parkinson's disease receiving rotigotine monotherapy experienced significantly greater improvements in parkinsonian symptoms (as measured by Unified Parkinson's Disease Rating Scale scores) compared to placebo in two large, well designed clinical trials. Significant beneficial effects versus placebo were observed with the 30 and 40 cm2 rotigotine patches in both trials.
View Article and Find Full Text PDFTrandolapril/verapamil sustained release (SR) [Tarka] is an oral, fixed-dose combination of the ACE inhibitor trandolapril and the SR formulation of the phenylalkylamine calcium channel antagonist verapamil. It is indicated for the treatment of hypertension in patients who require more than one agent to achieve blood pressure (BP) targets. In the large, randomised, multicentre INVEST (INternational VErapamil SR/trandolapril STudy), a verapamil SR-based treatment strategy that included trandolapril in most patients was as effective as an atenolol-based treatment strategy in reducing the risk of the primary outcome (first occurrence of death [all-cause], nonfatal myocardial infarction [MI] or nonfatal stroke) in patients with hypertension and coronary artery disease (CAD) and was as well tolerated.

Maintenance therapy with combined salmeterol/fluticasone propionate is at least as effective in improving lung function and symptoms and is as well tolerated in patients with asthma as concurrent salmeterol plus fluticasone propionate. In patients previously receiving as-required short-acting beta(2)-agonists (SABAs) or inhaled corticosteroids, salmeterol/fluticasone propionate was significantly more effective in providing asthma control than fluticasone propionate and in improving lung function and asthma symptoms than inhaled corticosteroids (at equivalent or higher dosages), salmeterol or montelukast (as monotherapy or in combination with fluticasone propionate).

As a component of an antiretroviral regimen, oral tenofovir DF 300 mg once daily effectively reduces viral load in patients with HIV infection who are treatment-experienced with baseline NRTI resistance mutations or treatment-naive. Tenofovir DF provides a simple and convenient once-daily dosage regimen, and is generally well tolerated and able to produce sustained suppression of viral replication.

Insulin aspart administered immediately before meals provided significantly greater improvements in glycosylated haemoglobin and better postprandial glycaemic control than regular human insulin administered 30 minutes before meals, when used in a basal-bolus regimen with neutral protamine Hagedorn (NPH) insulin, in randomised, nonblind studies in patients with type 1 diabetes mellitus. In patients with type 2 diabetes, insulin aspart provided similar glycaemic control to regular human insulin, administered in a basal-bolus regimen with NPH insulin.

In three large, well designed trials, subcutaneous fondaparinux 2.5mg once daily was more effective than subcutaneous enoxaparin sodium (enoxaparin) 30 mg twice daily or 40 mg once daily at preventing venous thromboembolism (VTE) at day 11 in patients undergoing hip replacement, elective major knee or hip fracture surgery; a fourth trial demonstrated similar efficacy to enoxaparin 30 mg twice daily in hip replacement.

In two 12-week, randomised studies in patients with asthma, ciclesonide 80 or 320 microg once daily was at least as effective as budesonide 400 microg/day at increasing forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) from baseline; ciclesonide 320 microg daily was significantly more effective than budesonide 400 microg once daily in one study. In a randomised, double-blind study in patients with asthma controlled with high-dosages of inhaled corticosteroids, FEV(1) and FVC decreased significantly from baseline at 12 weeks in patients receiving ciclesonide 320 microg daily or budesonide 400 microg daily; peak expiratory flow values decreased significantly only in patients receiving budesonide.

In two large, randomised, double-blind, 12-month studies, patients with severe chronic obstructive pulmonary disease (COPD) receiving budesonide/formoterol 320/9 microg twice daily had a significantly higher forced expiratory volume in 1 second (FEV1) and significantly higher morning and evening peak expiratory flow at trial endpoint than recipients of budesonide or placebo; FEV1 was significantly higher than with formoterol in the larger study. In both studies, the rate of COPD exacerbations and exacerbations requiring oral corticosteroids was significantly reduced with budesonide/formoterol versus formoterol and placebo.
View Article and Find Full Text PDFCetuximab is a chimeric monoclonal antibody highly selective for the epidermal growth factor receptor (EGFR), which is over-expressed by 25-80% of colorectal cancer tumours and associated with advanced disease. Cetuximab induces a broad range of cellular responses in tumours expressing EGFR, enhancing sensitivity to radiotherapy and chemotherapeutic agents. In a large, randomised, open-label, multicentre study in adult patients with irinotecan-refractory, metastatic colorectal cancer expressing EGFR, cetuximab 400 mg/m2 initial dose followed by 250 mg/m2 weekly plus irinotecan (various doses) produced a greater rate of partial response and disease control (partial response plus stable disease), and increased time to disease progression, compared with cetuximab monotherapy; survival was similar in both groups.
