There are about 3194 clinical studies being (or have been) conducted in Portugal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The objective of this trial is to collect evidence for the safety and efficacy of 24 weeks of treatment with BI 201335 240 mg in combination with 24 or 48 weeks of Pegylated Interferon (PegIFN) and ribavirin (RBV) in treatment experienced patients who have been withdrawn from PegIFN and RBV treatment due to lack of efficacy in the 1220.7, 1220.30 and 1220.47 trials.
The purpose of this trial is to assess the antiviral activity and safety of a dolutegravir (DTG) containing regimen in HIV-1 infected, antiretroviral therapy (ART)-experienced adults with current or historical failure on an integrase inhibitor (INI) containing regimen. The study will assess DTG 50mg twice daily administered initially with the current failing ART regimen but then with an optimised background ART regimen (OBR) after Day 7. The first analyses will be conducted after the last subject enrolled has completed 24 weeks. Subjects may remain on study after Week 24.
The purpose of this study is to investigate the efficacy of a treatment with TMC435 in combination with peginterferon alfa-2a and ribavirin in patients who did not clear their hepatitis C infection with peginterferon alfa-2a and ribavirin alone within a previous trial conducted by Tibotec, or who participated in Tibotec trials in which antivirals directed against hepatitis C virus (HCV) were evaluated for short periods of time.
This is a multicenter, randomized, double-blind, placebo-controlled Phase 3 study to compare the progression free survival, overall response rate (ORR) and safety of participants treated with lenvatinib 24 mg by continuous once daily oral dosing versus placebo. The study is conducted in 3 phases: a Prerandomization Phase (screening and baseline period), a Randomization Phase (double-blind treatment period), and an Extension Phase (Optional Open Label (OOL) Lenvatinib Treatment Period and a follow-up period).
This study will describe the long-term safety and effectiveness, treatment patterns,and patient reported quality of life associated with ranibizumab treatment in routine clinical practice for all approved indication included in the local product label.
This observational study will assess the long-term efficacy and safety of MabThera/Rituxan in routine clinical practice in patients with sero-positive rheumatoid arthritis who are non-responders or intolerant to a single tumour necrosis factor (TNF) inhibitor. Data will be collected from each patient over 2 years.
The purpose of the study was to evaluate the safety and efficacy of the emtricitabine (FTC)/rilpivirine (RPV)/tenofovir disoproxil fumarate (TDF) single-tablet regimen (STR) compared with the efavirenz (EFV)/FTC/TDF STR in HIV-1 infected adults who had not previously received treatment with antiretroviral medications. Participants were randomized in a 1:1 ratio to receive one of the study treatments. Randomization was stratified by HIV-1 RNA level (≤ 100,000 copies/mL or > 100,000 copies/mL) at screening. A treatment duration of 96 weeks was planned, with the option for subjects in FTC/RPV/TDF STR arm to receive treatment following the Week 96 visit until FTC/RPV/TDF STR is commercially available or until Gilead Sciences elects to terminate development in that country.
Primary Objective: - To demonstrate the superiority of cabazitaxel plus prednisone at 25 mg/m^2 (Arm A) or 20 mg/m^2 (Arm B) versus docetaxel plus prednisone (Arm C) in term of overall survival (OS) in participants with metastatic castration resistant prostate cancer (mCRPC) and not previously treated with chemotherapy. Secondary Objectives: - To evaluate safety in the 3 treatment arms. - To compare efficacy of cabazitaxel at 20 mg/m^2 and 25 mg/m^2 to docetaxel for: - Progression Free Survival (PFS) (RECIST 1.1) - Tumor progression free survival (RECIST 1.1) - Tumor response in participants with measurable disease (RECIST 1.1), - PSA response - PSA-Progression free survival (PSA-PFS). - Pain response in participants with stable pain at baseline - Pain progression free survival - Time to occurrence of any skeletal related events (SRE) - To compare Health-Related Quality of Life (HRQL). - To assess the pharmacokinetics and pharmacogenomics of cabazitaxel.
This multi-center study evaluates the safety and efficacy of vemurafenib in participants with BRAF V600 mutation-positive, surgically incurable, and unresectable Stage IIIC or IV (American Joint Committee on Cancer [AJCC]) metastatic melanoma.
The purpose of this study is to focus on potential differences in the occurrence of new-onset Diabetes Mellitus (a glucose metabolism disorder) when two different regimens of immunosuppressive treatment are compared.
