Psoriasis (PsO) is a systemic immune disease that affect 2-4% of the population worldwide. PsO causes tremendous burden in terms of quality of life, psychological impact, disability and work productivity of affected individuals. PsO is associated with an increased risk of cardiovascular morbidities and mortality in the long term. Up to 30% of PsO patients develop psoriatic arthritis (PsA) over time causing joint deformities and further disabilities. Majority of patients with PsA developed PsO first, and arthritis develop 5-10 years after. PsA and PsO are increasingly recognized as two entities under the umbrella of psoriatic diseases. Advances in biological treatments have greatly improved the prognosis of patients with PsO. Remarkable efficacies have been demonstrated for patients with moderate to severe PsO in randomized controlled trials (RCTs). However, the high cost of biological treatment is one of the major barriers to its prescription and many patients may have limited access to these treatments. The best treatment strategy for PsO that takes into account efficacy and cost effectiveness is unknown. For instance, whether some PsO patients can stop biological treatment and be treated with non-biologic medications upon relapse, which may enhance cost effectiveness of treatment. Preliminary studies have shown that some PsO patients were able to maintain good control of disease without medications after biologics withdrawal. The patho-immunological mechanisms behind long term remission after drug withdrawal is poorly understood. Better understanding of these mechanisms in maintaining remission and relapses will advance the development of biomarkers that eventually guide development of best treatment strategies for PsO. Secukinumab targets interleukin (IL)-17a and is highly efficacious in the treatment of plague PsO with a favorable safety profile. Some patients may have the response maintained after withdrawal of secukinumab. With the proven efficacies, sustainability after withdrawal and safety profile, secukinumab could be a choice of initial treatment for patients with moderate to severe PsO. Secukinumab has been recommended as first line treatment for selected patients with moderate to severe PsO by the American Academy of Dermatology and the European S3 guidelines. However, the use of biologics as first line is limited by cost issue. Overall, real-life data on biologic treatment for moderate to severe PsO is scanty.
This is a single center, randomized, phase Ib/II open-label study of pembrolizumab (pembro or MK-3475) with or without bevacizumab in patients with recurrent non-curable or metastatic nasopharyngeal carcinoma (NPC).
With the growing burden of dementia (including Alzheimer's disease), and the lack of efficacious therapies, there is an urgent need to identify new therapeutics. Ergothioneine (ET) is a naturally occurring thiol derivative of histidine, obtained solely through diet and is able to accumulate in the body and brain, through the action of a specific transporter, OCTN1. In addition to a wide variety of in vitro and in vivo (animal) studies demonstrating the antioxidant, anti-inflammatory properties of ET, several studies have demonstrated the neuroprotective potential of ET in various cell and animal models. Based on the ability of ET to counteract the underlying pathology of AD dementia, it is hypothesize that ET supplementation may prevent cognitive decline, especially in individuals at risk of cognitive impairment. This will be assessed using a randomized, double blinded, placebo-controlled, intervention study to test the ability of ET to delay or reverse cognitive impairment in elderly individuals with mild cognitive impairment.
This study aims to evaluate the safety and efficacy of new ablation catheter developed by MEDICAL TAEWOONG for the treatment of pancreatic neoplasm (pancreatic adenocarcinoma or neuroendocrine tumour). The ablation is performed using EUSRA needle and radio frequency waves under ultrasound imaging. The subject who will be recruited into this study are patients who are deemed as non-surgical candidates.
Clinical significance and current evidence: Radiation dermatitis occurs commonly in patients receiving chemoradiation for nasopharyngeal cancer; 50 to 60% develop grade 2 or higher dermatitis. This can result in significant morbidity, reduced aesthetic appearance, decrease in quality of life and delays in treatment. Current literature does not conclusively support the use of one agent over another for prevention of radiation dermatitis. The choice of agents used in clinical practice is highly variable, with aqueous agents being one of the commonest. Specific Aims: The aim of this study is to evaluate if the investigational product (StrataXRT), a silicone-based gel, is superior to standard clinical practice in prevention of grade 2 or higher acute dermatitis in patients receiving chemoradiation for nasopharyngeal carcinoma. Trial Design: The study will be conducted using a prospective, double-blind randomized control trial in 2 institutions. Each arm will receive standard radiation to a total dose of 70 Gray (Gy) with concurrent chemotherapy. The primary objective is to compare the prevention of dermatitis and the primary endpoint is reached when grade 2 or higher dermatitis according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03 scale occurs. Secondary objectives will be evaluation of the time to onset of dermatitis, the time to complete recovery from dermatitis and the degree of pain. Assessment of the patient's skin will be done at baseline, weekly during treatment, 1 week post treatment and unless the skin has resolved to baseline then every week up until 6 weeks post-treatment, which will mark the end of follow-up. The safety end-point is reached when grade 4 dermatitis occurs. Hypothesis and statistics: The investigators aim to demonstrate a 30% reduction in the incidence of grade 2 or higher dermatitis with StrataXRT. Using a 2-sided test at significance level 0.05 to detect the difference with a power of 80%, the investigators envisage a recruitment of 100-150 patients in total. The study duration is estimated to be 2 years.
In this protocol, the investigators propose a randomised controlled trial to explore the effects of intra-nasal oxytocin administration on appetite regulation. The investigators will run a cross-over design with 60 healthy adult men.
This study is a prospective, randomized, non-blinded study. 1 group will be assigned the standard arm with use of heparinised saline (10U/ml) lock in between each catheter use. This is consistent with the standard procedure of PICC care in the investigators' centre. The second group will be assigned the intervention with use of 4% citrate lock (Dirinco Citra-Lock 4%) in between each catheter use.
This is a multi-center, open-label, phase II study of durvalumab in combination with lenalidomide for treatment of relapsed/refractory NK/T-cell lymphoma (NKTCL). The study will employ a 2-stage Simon Optimal design with 80% power and type 1 error rate (significance level) of 5%. Stage 1 will involve 8 patients and will require at least 2 patients to achieve the primary end point of overall response in order to proceed onto to stage 2, which will have a target enrolment of 14 patients.
The purpose of this study is to evaluate the clinical outcomes of transcatheter aortic valve Replacement (TAVR) in the Asian Pacific population
Importance This will be a proof of concept study - whereby we hypothesize that Repigel may represent a paradigm shift in global acne treatment. Historically, there has been a dearth of clinical evidence in this use of povidone-iodine for inflammatory acne. This is likely due to staining related to iodine use, which is not acceptable to consumers. The trial drug, Povidone Iodine, however, becomes colourless and odourless in a matter of seconds after application on the skin. This represents an ideal product for which we may perform testing to look at its efficacy in the management of acne. A mainstay in the pathogenesis of acne involves the overgrowth and proliferation of skin micro-organisms, primarily proprionibacterium Acnes. Long term antibiotic therapy is usually prescribed for a period of 3 to 6 months or more. Previous studies have revealed this form of antibiotic therapy is ineffective, patients are usually poorly compliant, and also results in the formation of antibiotic resistant micro-organisms,which in turn reduces treatment efficacy. Potential Benefits As such, Povidone Iodine with its antiseptic property represents a promising avenue for the elimination of Proprionibacterium Acnes without the associated problems of long term antibiotic use, and the development of antibiotic-resistance. It is cosmetically acceptable, affordable, and easy to use.
