There are about 3491 clinical studies being (or have been) conducted in Singapore. 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.
To assess the efficacy of 2 doses of voclosporin compared to placebo in achieving complete remission after 24 weeks of therapy in subjects with active lupus nephritis.
In epithelial cancer, MUC-1(mucin-1) overexpression is thought to disrupt E-cadherin function, leading to anchorage-independent tumor cell growth and metastases. Elevated levels of MUC-1 expression have been found in patients with epithelial cancers of breast, ovarian, colon and lung. Furthermore, overexpression of MUC-1 is independently correlated with adverse clinical phenotypes, metastases and resistance to chemotherapy. In animal models, suppressing the expression of MUC-1 reduces the rates of growth and metastasis and increases the sensitivity of the cancer to chemotherapy-induced cell death. In this study, an adenoviral Ad-sig-hMUC-1/ecdCD40L vector encoding a fusion protein in which the hMUC-1 epithelial antigen is attached to the CD40L (CD40 ligand). The preclinical results have also shown that two subcutaneous Ad-sig-hMUC-1/ecdCD40L vector injections can induce immunity through activation of dendritic cells and promotion of antigen specific B cells or antigen specific CD8 effector T cells which suppresses the growth of hMUC-1 tumor cells in 100% of the vaccinated mice without Interleukin (IL) 2 stimulation being required, this suggests that the Ad-sig-hMUC-1/ecdCD40L vector prime-hMUC-1/ecdCD40L protein boost has the potential to be an effective vaccine in epithelial tumors. Therefore, the safety and tolerability of the Ad-sig-hMUC-1/ecdCD40L vector vaccine will be tested in this phase I non-randomized open label dose escalation trial for men or women with metastatic or recurrent epithelial cancers of the lung, breast, ovary, prostate and colon.
This study is carried out to determine the merit and reliability of extensive intraoperative peritoneal lavage as a preventive strategy Hypothesis: EPL significantly improve the overall survival of patients by reducing the risk of peritoneal recurrence
This study is a 2-arm randomized, controlled, multi-center clinical trial to determine which of two strategies at birth are best to optimally aerate the lung of preterm infants. Specifically we will determine in 600 infants of 23-26 weeks gestational age (GA) requiring respiratory support at birth which of two lung opening strategies - either a standard PEEP/CPAP of 5-7 cm H2O in the delivery room (DR), as compared to early lung recruitment using Sustained Inflation (SI) in the DR, will result in a lower rate of the combined endpoint of death or bronchopulmonary dysplasia (BPD) at 36 weeks gestational age. Hypotheses: 1. Early lung recruitment with SI superimposed upon standard PEEP/CPAP in the DR will reduce the need for mechanical ventilation in the first seven days of life, and reduce need for surfactant use; and 2. A policy of DR SI on standard PEEP/CPAP recruitment will confer better outcomes at 36 weeks post-menstrual age (PMA) than standard PEEP/CPAP
This is a multicenter, Phase III, randomized, double-blind, double-dummy, parallel-group study to evaluate the safety, efficacy, and tolerability of etrolizumab compared with infliximab in treating participants with moderate to severe ulcerative colitis (UC) who are naive to tumor necrosis factor (TNF) inhibitors. Participants will be randomized in a 1:1 ratio to receive either etrolizumab 105 milligrams (mg) by subcutaneous (SC) injection once every 4 weeks (Q4W) + placebo (intravenous [IV] infusion at Weeks 0, 2, and 6, then once every 8 weeks [Q8W]) or infliximab 5 milligrams/kilogram (mg/kg) IV at Weeks 0, 2, and 6, then Q8W) + placebo (SC Q4W). Time on treatment is 54 weeks.
There are two study questions we are asking in this randomized phase II/III trial based on a blood biomarker, Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) for locoregionally advanced non-metastatic nasopharyngeal cancer. All patients will first undergo standard concurrent chemotherapy and radiation therapy. When this standard treatment is completed, if there is no detectable EBV DNA in their plasma, then patients are randomized to either standard adjuvant cisplatin and fluorouracil chemotherapy or observation. If there is still detectable levels of plasma EBV DNA, patients will be randomized to standard cisplatin and fluorouracil chemotherapy versus gemcitabine and paclitaxel. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, fluorouracil, gemcitabine hydrochloride, and paclitaxel work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cisplatin and fluorouracil is more effective than gemcitabine hydrochloride and paclitaxel after radiation therapy in treating patients with nasopharyngeal cancer.
Background and rationale: Antimicrobial resistance is a global public health threat. An increasing number of Gram-negative bacteria isolates worldwide are resistant to virtually all antibiotics including carbapenems. Although polymyxins are the current gold standard antibiotic for treatment of severe extensively drug-resistant Gram-negative bacteria (XDR-GNB - defined in Appendix I) infections, resistance development on therapy and treatment failures are common. Combination antibiotics therapy have better in vitro efficacy, but have not been formally tested in a prospective trial. We will conduct a Phase IIB, prospective, open-label, randomized-controlled trial in 4 major Singaporean hospitals, with balanced treatment assignments achieved by permuted block randomization, stratified by hospital. There will be 75 subjects per arm, with the subjects in the comparator arm receiving standard-dose polymyxin B while the intervention arm will receive a second antibiotic, doripenem, with polymyxin B against the bacterial isolate in question. Subjects with ventilator-associated pneumonia (VAP) will additionally receive nebulized colistin. The primary outcome is 30-day mortality while secondary outcomes include microbiological clearance, time to defervescence, and toxicity of therapy, presence of secondary infections due to new multi-drug resistant bacteria and length of ICU stay. Plasma drug levels will be measured by liquid chromatography-mass spectrometry. Hypothesis: The underlying primary hypothesis is that combination antibiotic therapy (IV polymyxin B + IV doripenem) is superior to mono-antibiotics therapy (IV polymyxin B) in reducing 30-day mortality from XDR-GNB infections.
This randomised, double-blind phase III trial will be performed in patients with head and neck squamous cell carcinoma (HNSCC). The objectives of the trial are to compare the efficacy and safety of afatinib (BIBW 2992) with placebo as adjuvant therapy to patients who have received definitive chemo-radiotherapy.
Phase 3, 2-arm, randomized, open label trial. Patients will be randomized to receive bosutinib or imatinib for the duration of the study.
Background - In patients with critical limb ischaemia (CLI), the infragenicular arteries are often involved. Without revascularisation, amputation often is imperative. There is a high technical success rate of endovascular revascularisation of infragenicular arteries with percutaneous transluminal angioplasty (PTA), but mid- and long-term results are disappointing as restenosis frequently occurs. Drug-eluting balloon (DEB) PTA has been shown to improve patency rates after PTA of coronary arteries. Aim - To study the results of DEB-PTA compared to conventional balloon CB-PTA for the treatment of infragenicular lesions in patients with CLI. - To evaluate cost-effectiveness of DEB-PTA versus CB-PTA in patients with critical limb ischemia (CLI) by quantifying the incremental cost-effectiveness ratio (ICER). Hypothesis - DEB PTA results in improved patency rates compared to CB-PTA for treatment of infragenicular arterial lesions in patients with CLI. - DEB-PTA is a cost-effective strategy in patients with CLI compared with CB-PTA. Methodology Multi-center, prospective, randomised parallel-group trial. Patients are eligible for enrolment if they have CLI and at least one infragenicular lesion with a maximal total lesion length of 20cm. Randomisation will be performed on a 1:1 ratio to either DEB-PTA or CB-PTA. Patients will be assessed prior and directly after the intervention, at 3, 6 and 12 months by Rutherford classification, ankle-brachial index, toe pressure and adverse events. Duplex will be performed at 3 months. Angiography will be performed before and directly after PTA and at 6 months. Primary end-point will be primary patency of the treated lesions at 6 months on angiography (defined as <50% stenosis, without re-intervention in the interim). Secondary end-points are limb salvage at 3, 6 and 12 months, primary patency of the treated lesion on Duplex at 3 months (defined as patency of the treated artery with peak systolic velocity (PSV) ≤2.0 m/sec), Rutherford classification, minor and major amputation, infrapopliteal endovascular re-intervention, patency of treated femoropopliteal sites (if applicable), infrapopliteal surgical bypass, peri-procedural complications and death at 3, 6 and 12 months. A cost-effectiveness analysis (CEA) from a societal perspective will be performed in parallel with the randomized clinical trial with a 12-month time horizon.
