The primary objective is to assess the antihypertensive efficacy of 4 different AVE 7688 doses on the change from baseline in trough diastolic blood pressure at the end of week 12. The secondary objectives are: - To assess the antihypertensive efficacy of 4 different AVE 7688 doses on the change from baseline in trough systolic blood pressure at the end of week 12 - To compare the percentages of responders after 12 week of treatment - To evaluate the long term safety and tolerability of AVE 7688 with particular attention to angioedema
The purpose of this study is to assess whether Lyrica is a safe and effective treatment for partial epilepsy in comparison with an established treatment, Lamictal.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This clinical trial is studying giving radiation therapy or combination chemotherapy to see how well it works in treating patients with clinically or radiologically progressive low-grade gliomas.

The objective of the study was to evaluate the degree of improvement in lung function in patients with chronic obstructive pulmonary disease (COPD) after treatment with tiotropium inhalation capsules compared to salmeterol inhalation aerosol .
Primary: - To assess the efficacy of SR121463B in correcting hyponatremia in patients with dilutional hyponatremia other than SIADH or cirrhosis Secondary: - To assess the long-term efficacy of SR121463B in maintaining normonatremia in these patients - To assess the safety and tolerability of SR121463B
- 1.To compare overall survival after treatment with the test tri-therapy (TPF: docetaxel plus cisplatin and 5FU) or the control treatment (PF: cisplatin plus 5-FU) followed by chemoradiotherapy in patients with locally advanced SCCHN. - 2.The main secondary endpoint is progression free survival (PFS). The other secondary endpoints are to evaluate and compare improvement of local symptoms; time-to-treatment failure; quality of life; clinical complete response rate (CR and CR/PR); toxicity and to evaluate the relationship of tumor markers and response to therapy.
The purpose of this study is to evaluate the safety, tolerability and antiviral effects of atazanavir (ATV) plus ritonavir (RTV) versus a combination drug of lopinavir (LPV) plus RTV. A combination drug containing tenofovir (TDF) and emtricitabine (FTC) will also be taken by participants in both arms.
