All clinical trials

The goal of this clinical trial is to compare the safety and effect on visual acuity of three different doses of SYL1801 eye drops.

Breast cancer is the most prevalent cancer type worldwide. In Egypt, It is the second most common type of cancer and the most common one in women with about 22 thousand new cases in 2020. Around 70% of newly diagnosed patients are hormone receptor-positive and, unfortunately, the disease is often diagnosed at the advanced stage. In postmenopausal women with hormone receptor-positive breast cancer, aromatase inhibitors (AIs) are the first-line adjuvant therapy according to National Comprehensive Cancer Network (NCCN) guidelines. Although, they showed superiority in efficacy to tamoxifen in this type of breast cancer, one of the most annoying adverse effects of the aromatase inhibitors are the vasomotor symptoms. They could be as severe as the patient would prefer discontinuing the medication. The underlying mechanism responsible for those adverse effects is that AIs suppress plasma estrogen levels by inhibiting the enzyme responsible for the conversion of androgens to estrogens in peripheral tissues. This estrogen depletion has been linked to an increase in hot flushes by decreasing endorphin levels and increasing that of norepinephrine and serotonin, followed by instability of the hypothalamic thermoregulatory set point which allows changes in the body temperature and in hot flash sensation. Hormone replacement therapy is considered first-line treatment for vasomotor symptoms. However, it is not preferred to be used in breast cancer patients especially those with hormone receptor positive breast cancer. So, many drugs have been investigated for their efficacy in reducing the frequency and severity of vasomotor symptoms. The only FDA-approved drug to treat moderate-to-severe vasomotor symptoms is paroxetine. Paroxetine is a selective serotonin reuptake inhibitor (SSRI) which is used mainly in major depressive disorder and other psychiatric conditions like anxiety disorders. It has proved an efficacy in reducing frequency and severity of hot flushes in post-menopausal women. But, there are several concerns regarding its use with tamoxifen in breast cancer patients. There is a competition between paroxetine and tamoxifen for hepatic CYP2D6, so, paroxetine prevents conversion of tamoxifen into its active metabolite. Oxybutynin has shown efficacy in relieving vasomotor symptoms. Oxybutynin is an anticholinergic used usually in urinary incontinence. It has an advantage over other SSRIs that it lacks the interaction with tamoxifen on CYP2D6 and, therefore, with the anticancer effect of tamoxifen treatment in breast cancer patients. To our knowledge, there are no head-to-head studies comparing the efficacy and safety of paroxetine versus oxybutynin in reducing frequency and severity of vasomotor symptoms especially in breast cancer patients taking aromatase inhibitors.

To investigate the influence of low intensity pulsed ultrasound on Pain level, pinch grip strength, sensory distal latency of the median nerve, motor distal latency of the median nerve and hand function in patients with chronic carpal tunnel syndrome

This study will evaluate the feasibility of transcranial direct current stimulation (tDCS) as an adjunct to an outpatient motor skills-based physiotherapy intervention for children and youth with acquired brain injury. Up to 10 children (age 5-18 years) with childhood onset stroke or traumatic brain injury will be randomly allocated to receive active or sham anodal tDCS immediately prior to the physiotherapy session. These sessions will occur twice weekly for a total of 10 sessions. Assessment of gross motor outcome measures will occur immediately before and after the combined tDCS and physiotherapy treatment protocol. The preliminary treatment effect between the two treatment groups will be compared and other feasibility indicators will be evaluated.

Recent observational data showed a marked reduction of vascular and bleeding complications by the use of ultrasound(US)-guided femoral artery puncture to gain the vascular access and guide the implantation of the Perclose ProGlide® vascular closure system. We aimed to compare in a 1:1 randomized fashion the effect of US-guided femoral puncture and Perclose ProGlide® implantation optimization vs fluoroscopy-guided puncture followed by Perclose ProGlide/ ProStyle implantation (standard approach) during TAVR.

The purpose of this study is to evaluate the safety and efficacy of once daily oral inhalation dose of MK-5475 380 µg in participants 40 to 80 years (inclusive) with Pulmonary Hypertension associated with Chronic Obstructive Pulmonary Disease (PH-COPD). The primary hypothesis of the study is MK-5475, a soluble Guanylate Cyclase (sGC) stimulator is superior to placebo in increasing 6 Minute Walking Distance (6MWD) from baseline at Week 24.

This is an interventional pilot study to determine whether implementation of a supervised exercise program can improve outcomes in subjects undergoing allogeneic HCT. The primary objective is to determine feasibility. Up to 60-72 evaluable subjects will be enrolled. Evaluable subjects are defined as those participating in the exercise intervention.

Supervised exercise training (SET) is considered among first-line therapies for patients with symptomatic lower extremity peripheral artery disease (PAD), combined with general cardiovascular risk management, lifestyle adaptation and pharmacological treatment. Although without clear consistency, the guidelines give recommendations in terms of claudication pain severity, SET volume, duration, and frequency. However, no or little guidance is offered as far as training intensity is concerned. Most of the previous studies on SET, in the context of PAD, did not distinguish between symptom intensity and common training intensity measures such as % of maximal heart rate (%HRmax), % of HR reserve (%HRR), % of peak oxygen uptake (%VO2peak), % of VO2 reserve (%VO2R), or the rate of perceived exertion (RPE). In a recent meta-analysis, we demonstrated that both training modality and exercise intensity (based on %peak heart rate, %peak oxygen uptake, or the rate of perceived exertion) should be considered when looking for the best results in patients with symptomatic PAD. These results call for study of the individual roles of each exercise intensity and modality on walking performance and cardiorespiratory fitness in patients with symptomatic PAD. High-intensity interval training (HIIT) is composed of brief bursts of vigorous intensity interspersed with periods of rest or low-intensity exercise. HIIT may be better than moderate-intensity training (MIT) in improving cardiorespiratory fitness and functional capacity in patients with cardiovascular and metabolic diseases, but in patients with symptomatic PAD, the effects of such modalities on walking ability and cardiorespiratory fitness remain to be clearly determined. The primary objective of this study is to compare the effects of 12-week-long exercise training (short-duration high-intensity intervals vs. low-to-moderate intensity) on treadmill performance in patients with symptomatic PAD. It is hypothesized that treadmill performance would be improved to a greater extent after high-intensity exercise training

This study will compare the safety and efficacy of curative radiotherapy to the prostate and lymph glands given in 5 visits to that of prostate alone radiotherapy given in 5 visits, in men with high risk localised prostate cancer.

The study aims to evaluate the clinical efficacy of Chinese medicine (CM) for the treatment of subacute and chronic Atopic Dermatitis (AD) patients when compared to the placebo control by examining the clinical symptoms.
