Hypothesis, HRT does not increase the risk of lupus activity exacerbation, it is effective for the relief of menopausal symptoms and improves bone mineral density. Double-blind, randomized, placebo controlled clinical trial. Objectives 1. Determine the effect of HRT on disease activity, menopausal symptoms, bone mineral density, lipid profile, and mammographic parenchymal density in menopausal women with SLE. 2. Determine the incidence rate of major side effects of HRT in menopausal women with SLE. Outcome Measures 1. Primary outcome will be global disease activity throughout the follow-up period. 2. Incidence of lupus flares, time to the first flare, changes in SLEDAI values from baseline at each follow-up visit, maximum disease activity, lupus treatment, hospitalizations, thromboses, and deaths. Menopausal symptoms and depression will be assessed utilizing the Greene Climacteric Scale questionnaire and the Beck Depression Inventory. Bone mineral density of lumbar spine and hip will be performed with dual energy x-ray absorptiometry. In addition, blood and urine samples to measure biochemical markers of bone turnover.

In addition, a gynecological examination will be performed. Criteria for early termination of the study: A patient will be discontinued from the study whenever any of the following criteria would be present: 1. Development of severe lupus activity (SLEDAI > 30). 2. Development of any putative complication to hormone therapy. 3. Development of any other severe complications due neither to SLE nor hormone therapy. 4. Need prolonged immobilization. Statistical analysis: Between-group comparisons of lupus activity, maximum SLEDAI, and change in SLEDAI score from baseline at each follow-up visit. Incidence-density rates of flares with relative risk and 95 percent confidence intervals.Probability of flares throughout the study using life-table analyses and log-rank test. Climacteric symptoms as the mean value of the Green’s scale score at baseline and at each follow-up visit, between-group and intra-group. Bone mineral density as the mean value at baseline, 12 and 24 months, between and intra-group. The proportion of patients in each group who develop secondary effects, as well as the number who quit the study during the follow-up period. Continuous variables will be compared using Student's t-test, and categorical variables using chi-square or Fisher’s exact test. Within-group comparisons will be done using the Wilcoxon signed-rank test. P values will be two-sided. Analyses will be conducted by the intention-to-treat method.
Ticagrelor is a new, reversible binding, anti-platelet medication. Anti-platelet medications work to prevent the formation of blood clots. Ticagrelor is being developed as a treatment for patients with acute coronary syndrome (ACS). ACS is a term that is used to describe both heart attacks in progress or the imminent threat of a heart attack. ACS is usually caused by the formation of a blood clot in an artery that partially or totally blocks the blood supply to a portion of the heart muscle. Ticagrelor will be compared with clopidogrel to determine which drug, when either is used in conjunction with aspirin, is better at reducing deaths from vascular causes, future heart attacks and/or strokes in patients with ACS.
The purpose of this randomized, double blind, double dummy, multicenter study was to evaluate the efficacy of risperidone long-acting injectable (LAI) monotherapy in comparison with placebo in the prevention of a mood episode in treatment of patients with bipolar I disorder. Oral olanzapine was used to assess the validity of the study design. The primary objective of this study is to evaluate the efficacy of risperidone LAI versus placebo in the prevention of a mood episode (recurrence event) in patients with bipolar I disorder after a 12-week (3 month) stabilization period on risperidone LAI, as measured by the time to recurrence of any mood episode. Risperidone LAI has been approved by the FDA in the USA for the treatment of patients with schizophrenia and for the prevention of mood recurrences in bipolar I disorder, as monotherapy or add-on treatment. It is approved at EMEA and other European and non-European health authorities for the treatment of patients with schizophrenia, too.
This randomized, multicenter, open-label, active-comparator, 2-arm, parallel-group, 6 month study with approximately 360 patients will compare the efficacy of two treatment regimens (Algorithm A versus Algorithm B) in insulin-naive patients with type 2 diabetes not optimally controlled by one or more oral antihyperglycemic medications. Patients will be assigned randomly to receive one of the following treatment groups: Algorithm A is defined as a simplified diabetes management regimen starting with a fixed dose of HIIP (also known as AIR® Inhaled Insulin)(AIR® is a registered trademark of Alkermes,Inc.), titrating 2 times per week based on 2 times per week 4 point blood glucose values for the first month and titrating 1 time per week based on once weekly 4-point blood glucose values for the remainder of the study, increasing total daily dose by a maximum of 6 U per day. Algorithm B is defined as an intensive diabetes management regimen, starting with an adjusted dose of AIR® Inhaled Insulin, titrating 2 times per week based on daily 4 point blood glucose values, with sustained monitoring of dose and blood glucose throughout the study, increasing total daily dose by a maximum of 8 U per day.
The purpose of this study is to determine if CP-945,598 is effective in the treatment of obesity in type 2 diabetic patients.
This 2 arm study will compare the efficacy and safety of Avastin plus Herceptin/docetaxel, versus Herceptin/docetaxel alone, in patients with HER2 positive locally recurrent or metastatic breast cancer who have not received prior chemotherapy for their metastatic disease. Patients will be randomized 1:1 to receive either Avastin (15mg/kg iv q3weeks) + Herceptin (8mg/kg iv loading dose and 6mg/kg iv q3weeks maintenance) + docetaxel (100mg/m2 iv q3weeks) or Herceptin + docetaxel alone. The anticipated time on study treatment is until disease progression, and the target sample size is 100-500 individuals.
Primary purpose of this study is to compare the efficacy and safety of two different nevirapine (Viramune) dosing regimens (once daily (QD) and twice daily (BID) application) and of atazanavir/ritonavir (Reyataz/Norvir), all on an emtricitabine/tenofovir disoproxil fumarate (DF) (Truvada) background. Patients will receive either nevirapine (NVP) 200 mg twice daily, or NVP 400 mg once daily , or ritonavir-boosted atazanavir (ATZ/r), all in combination with emtricitabine (FTC) and tenofovir DF (TDF). All patients receiving NVP will start at 200 mg once daily for 2 weeks, because it has been demonstrated that this lead-in dosing regimen reduces the frequency of NVP-induced rash. At Visit 3 (Week 2), patients increase the NVP dose to either 200 mg twice daily or to 400 mg once daily. Patients receiving ATZ/r will be treated with ATZ 300 mg once daily, boosted by 100 mg ritonavir (RTV) once daily. Background antiretroviral therapy for all patients consists of one tablet of Truvada. Treatment duration is 48 weeks (primary endpoint) with an extension to 144 weeks. Patients may also participate in the metabolic sub-study, comparing NVP and ATZ/r for signs and symptoms of lipodystrophy and serum lipid/glycaemic abnormalities.
The purpose of this study is to prospectively assess the long-term outcomes (benefits and risks) associated with entecavir (ETV) therapy as compared to other antivirals approved for the treatment of chronic HBV infection. For the China substudy, patients randomized to entecavir will have safety and efficacy assessments performed during the first year of the study.
