Clinical trials

This is a phase IV, post-marketing, observational, cohort study for safety and effectiveness evaluation of Amitzo® in Iranian patients with grade III and IV glioma tumors. No control group is considered in the study design. The primary objective is to evaluate the incidence of hepatic injury in patients with grade III and IV glioma tumors, treated with Amitzo®.

Dopason is a phase I, open-label, multicenter, single-arm clinical trial designed to evaluate the safety and feasibility of intraputaminal transplantation of human embryonic stem cell-derived dopaminergic progenitor cells (DopaCells) in patients with moderately severe Parkinson's disease.

The present study will examine the effects of increasing dietary polyphenol intake by consumption of oregano and basil leaves, on plasma inflammatory and lipid factors and total urinary polyphenol levels in patients who have recently had unstable angina.

Parkinson's disease is commonly associated with impaired gait, postural instability, reduced physical function, and increased concern about falling, all of which contribute substantially to disability and reduced quality of life. Exercise-based rehabilitation is increasingly recommended as a core non-pharmacological strategy for improving mobility and balance in people with Parkinson's disease. In parallel, recent clinical and neurorehabilitation research suggests that eye-movement and gaze-stabilization training may influence postural control, visuomotor integration, and movement performance in neurological disorders, including Parkinson's disease. This randomized controlled trial will evaluate whether a supervised in-center eye-exercise program can improve physical function, balance, and fall-related concern in patients with Parkinson's disease.

This pilot randomized trial will evaluate whether a structured intradialytic eye-exercise program can be delivered safely and consistently during maintenance hemodialysis and whether it shows preliminary promise for improving physical function, balance, and fall-related concern. The study is needed because hemodialysis patients commonly experience impaired physical performance, reduced balance, and fear of falling, and these problems are associated with higher fall risk; at the same time, supervised exercise during dialysis is increasingly viewed as a practical way to reach this medically complex and often sedentary population. Eye-movement and gaze-stability training has also shown benefit for balance- and fall-related outcomes in older adults and stroke survivors, but its feasibility and potential value during dialysis sessions remain uncertain.

Liberation from mechanical ventilation involves three steps: weaning, readiness assessment, and extubation. Readiness is determined using clinical criteria such as improvement of the underlying condition, hemodynamic stability, and adequate respiratory effort. Successful extubation is defined as not requiring invasive support within 48 hours. Due to the complexity of ICU patients, various clinical parameters and multi-component scores have been developed to predict extubation success. This study aims to develop and evaluate a multi-component score, the Readiness for EXtubation score (REXs), to predict extubation readiness in ICU patients under invasive mechanical ventilation.

Benign prostatic hyperplasia (BPH) is one of the most common performed surgical procedures in urology. Over the past few decades there have been an increasing development of newer surgical treatment options. Additionally, the outcome parameters for BPH treatments have been standardized. While data are available for the initial pivotal studies, post-market release data are lacking. Under the umbrella of uCARE, we have started a prospective, ongoing international registry for recording demographics and outcomes for patients undergoing surgical treatments for BPH.

Pain management is a core competency in nursing practice, yet nursing students consistently demonstrate insufficient knowledge, unfavorable attitudes, limited competence, and low self-efficacy in this area. Artificial intelligence (AI)-based educational tools, particularly ChatGPT, have emerged as promising resources in nursing education; however, rigorous experimental evidence on their effectiveness remains scarce. This study is a two-arm, parallel-group randomized controlled trial (RCT) that aims to evaluate the effect of a ChatGPT-driven blended teaching model for pain management on nursing students' knowledge and attitudes toward pain, nursing competence, and learning self-efficacy. Eligible nursing students at Shahid Beheshti University of Medical Sciences (Tehran, Iran) will be randomly assigned in a 1:1 ratio to either: * Intervention group: ChatGPT-assisted blended clinical nursing rounds (8 sessions over 4 weeks, each 90 minutes, combining bedside rounds with AI-assisted pre- and post-round activities) * Control group: Traditional clinical nursing rounds (same number and duration of sessions, without any AI tools) Outcomes will be measured at baseline (1 week before intervention), immediate post-test (1 week after intervention), and 3-month follow-up using validated instruments: the Nurses' Knowledge and Attitudes Survey Regarding Pain (NKASRP), the Nursing Student Competence Scale (NSCS), and the Nursing Students' Learning Self-Efficacy instrument (NLSE). Findings will provide empirical evidence to guide educational policy and curriculum design in nursing programs, with the goal of improving pain management education and patient care outcomes.

Acute low back pain is one of the most common health problems in the world. Most people experience it at least once in their lives, and although many cases improve within a few weeks, a significant number of patients continue to struggle with pain, fear of movement, stress, and reduced daily function. These psychological factors-such as catastrophizing ("my back is damaged"), fear of movement ("if I move, it gets worse"), and avoidance behaviors-can slow recovery and increase the risk of the pain becoming chronic. Pain Neuroscience Education (PNE) is a modern educational approach that teaches patients how pain actually works in the nervous system. Instead of focusing only on muscles and bones, PNE helps people understand how the brain interprets pain, why pain can persist even without serious injury, and how thoughts, emotions, and behaviors can influence the experience of pain. Research shows that PNE can reduce fear, improve movement, and help people participate better in rehabilitation-especially in chronic pain. However, there is very limited high-quality evidence about its effects in acute low back pain. The purpose of this study is to determine whether adding Pain Neuroscience Education to routine physiotherapy can improve recovery in people with acute low back pain. To do this, the investigators will conduct a single-blind randomized clinical trial with two groups of patients: Control group: Receives conventional physiotherapy, including soft-tissue mobilization and TENS, along with routine patient education about posture and back care. Intervention group: Receives the same physiotherapy plus two structured sessions of Pain Neuroscience Education, delivered individually using simple explanations, metaphors, and visual materials. Both groups will receive eight treatment sessions over four weeks. The investigators will measure several important outcomes before starting treatment and immediately after the 8th session, including: Pain intensity Functional disability Pain catastrophizing Fear-avoidance beliefs Fear of movement (kinesiophobia) The investigators' hypothesis is that patients who receive PNE in addition to routine physiotherapy will show greater reductions in pain, disability, fear, and catastrophizing compared to those receiving physiotherapy alone. If proven effective, this approach could provide a simple, low-cost, and safe addition to physiotherapy that not only reduces pain but also prevents acute low back pain from turning into a chronic condition. This could help improve patients' quality of life and reduce the economic and healthcare burden caused by low back pain.

Fractures of the lower extremities represent a significant proportion of injuries sustained by polytrauma patients, with a notable association with prolonged hospitalization, chronic disability, and impaired physical functioning. The occurrence of surgical site infections (SSI) represents a significant threat to the efficacy of osteosynthesis procedures. As with other traumas and surgical procedures, the secretion of inflammatory mediators is markedly elevated in this cohort of patients following surgery. Naringenin is one of the most prevalent flavonoids, occurring naturally in grapefruit and other citrus fruits. In vitro studies have demonstrated that naringenin may stimulate the release of osteogenic cytokines and suppress the production of pro-inflammatory factors, which can result in a reduction in bone resorption. Based on these findings, naringenin may prove an effective agent for accelerating the rate of fusion and controlling inflammation. Furthermore, it may enhance quality of life and augment functional activity.

Post-transplant obesity is a common complication after kidney transplantation, largely attributed to recovery from uremia, increased appetite, sedentary lifestyle, and long-term corticosteroid exposure. Obesity in kidney transplant recipients increases the risk of cardiovascular disease, post-transplant diabetes mellitus (PTDM), and may contribute to graft injury through hyperfiltration-related mechanisms, potentially leading to reduced graft survival. Current approaches for weight management in transplant recipients, including lifestyle modification, are often insufficient, while bariatric surgery carries considerable risks and concerns regarding altered absorption of immunosuppressive medications. Tirzepatide (Iranian brand name: Spartina), the first dual agonist of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, has demonstrated superior effects on weight reduction and glycemic control compared with earlier GLP-1 receptor agonists in the general population. However, its use in kidney transplant recipients requires careful evaluation due to potential gastrointestinal adverse effects, dehydration risk, and possible interaction with calcineurin inhibitor absorption caused by delayed gastric emptying. This prospective single-arm pilot clinical trial aims to assess the preliminary safety and efficacy of tirzepatide in obese kidney transplant recipients with stable graft function. Outcomes include changes in anthropometric indices, percent weight change, gastrointestinal tolerability, immunosuppressive drug trough levels, and graft function over 24 weeks of treatment.

Chronic active antibody mediated rejection (CAMR) is a therapeutic challenge in transplant recipients that does not respond well to conventional treatments for acute antibody mediated rejection (AMR). Annually, 5000 kidney transplants are lost in the United States due to CAMR. The two-year graft survival rate in CAMR is approximately 20%, highlighting the need for a more efficient therapy for CAMR and directly targeting donor specific antibody (DSA) producing cells and reducing CAMRThere is no established treatment for this problem. While many centers intensify and optimize the dosage of immunosuppressive drugs, treatments such as plasmapheresis, IVIG, and rituximab, although effective in treating AMR, have not been successful in reducing DSA or improving kidney graft survival in CAMR patients. Despite these treatments, two-year graft survival can increase up to 55%. The use of anti-plasma cell treatments like bortezomib has also yielded inconsistent results.

This prospective single-arm interventional study evaluates the recurrence rate and functional outcomes following conjunctival transpositional pterygium surgery without bare sclera formation. The technique involves mobilization and transposition of the pterygium tissue while preserving Tenon's layer and avoiding adjunctive therapies.

Polycystic Ovary Syndrome (PCOS) is one of the most common endocrine disorders among women of reproductive age and is associated with metabolic abnormalities such as insulin resistance, dyslipidemia, and hormonal imbalance, which may lead to infertility and hirsutism. Despite the availability of several pharmacological treatments, many therapies fail to effectively address the underlying metabolic and endocrine dysfunctions of PCOS. Magnesium and L-carnitine are two essential nutrients that may play a synergistic role in improving insulin sensitivity, glucose metabolism, and lipid profile, as well as reducing oxidative stress and androgen production in women with PCOS. This randomized, triple-blind, placebo-controlled clinical trial aims to evaluate the effects of co-supplementation with magnesium and L-carnitine on glycemic control indices, lipid profile, and hirsutism in women with PCOS. A total of 84 eligible women aged 19-65 years diagnosed with PCOS according to the Rotterdam criteria will be recruited from Shohada Tajrish Hospital, Tehran, Iran. Participants will be randomly assigned to one of three groups: (1) magnesium supplementation (500 mg/day, in two 250 mg doses) plus L-carnitine placebo, (2) L-carnitine supplementation (1000 mg/day) plus magnesium (500 mg/day), or (3) placebo control group. The intervention period will last 12 weeks. Physical activity information will be collected using short form of International Physical Activity Questionnaire (IPAQ) and demographic information through a general information questionnaire. In order to evaluate dietary intake of patients in terms of energy(kcal/(day), carbohydrate(gr/day), protein(gr/day), fat intake(gr/day), saturated fatty acids (SFA) (gr/day), monounsaturated fatty acids (MUFA) (gr/day), polyunsaturated fatty acids (PUFA)(gr/day), Vitamin E (mg/day), Vitamin C (mg/day), Beta-carotene (mg/day) and Vitamin A (mg/day), cupper intake (mg/day), selenium intake (mg/day), and zink intake (mg/day), 24-hr recalls will be completed by interviewing the patient for 3 days (two normal days and a weekend day). Weight will be measured with the minimum dress and without shoes by using a digital balance scale of 100 grams and height will be measured without shoes by meters mounted to the wall with an accuracy of 0.5 centimeters. Then the body mass index will be calculated by dividing the weight (kg) by the square of the height (m), waist circumference will be measured in the narrowest area between the lowest lumbar spine and the iliac bone (cm), systolic and diastolic blood pressure will be measured after 15 minutes of rest, twice using the mercuric barometric measure and the mean will be reported as individual blood pressure. The blood sample will be taken after 12 hours of overnight fasting in three groups for measuring Fasting Blood Sugar (FBS) (mg/dL), lipid profile (mg/dL), Hemoglobin A1c (HbA1C) (percentage), serum insulin concentration (µIU/ml) and insulin resistance. Insulin resistance will be calculated using the Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) formula, and hirsutism score (using the modified Ferriman-Gallwey method) will be assessed at baseline and post-intervention. At the end of the study, counting the remaining capsules, the patient's compliance rate will be evaluated, and patients who have consumed less than 90% of their capsules will be excluded from the analysis.

The goal of this clinical trial is to Investigate the Effect of Injection of MSC-Derived Exosome on Patients with Erectile Dysfunction in overall healthy males, aged 18-70, with-out any severe active medical condition, with moderate to severe erectile dysfunction based on IIEF-5, and non-satisfactory response to other treatments (5PDEI). The main question it aims to answer is: • Is MSC-derived exosome safe and effective in treating patients with ED by improving IIEF-5 score? If there is a comparison group: Researchers will compare the intervention group (Exosome receiving group) with control group (placebo receiving group) to see if exosomes are safe and effective in treating male adult patients with moderate-sever ED. Participants will receive six weekly injections of normal saline or exosome (based on group), and will undergo necessarily follow up, and examinations and observation.

Warts caused by the human papillomavirus (HPV) are one of the most common skin conditions among children. The prevalence of warts in school-aged children ranges from 10 to 20 percent. Warts are more common among immunocompromised patients \[1, 2\]. Some studies also show that the prevalence of viral warts in the pediatric population increases with age, peaking in adolescence. HPV is a DNA virus that replicates only in fully differentiated epithelial cells. More than 80 types of HPV have been identified. Types 27, 57, 2, and 1 are the most common types of HPV in skin warts in the general population. Warts usually affect patients of different age groups and various parts of the body, causing physical and psychological complications for patients (such as pain, discomfort, and embarrassment), which in turn lead to functional impairment. Warts often affect pressure points on the soles of the feet. Although most warts are asymptomatic, plantar warts are often associated with pain while walking, causing physical and psychological stress \[3\]. Various treatments such as keratolytic agents, cryotherapy, laser, antimitotic treatments, contact sensitizers, and intralesional injection of antigen have been used. There is no evidence that one treatment is superior to others, and in many cases, treatment of viral warts requires a combination of treatments. Treatment selection for patients should be based on variables such as wart size, number of lesions, anatomical location, patient preference, cost, convenience, side effects, and operator experience. It is important to emphasize that good communication between the patient, parents, and dermatologist is essential for successful treatment in children \[2, 4\]. Despite having various treatment approaches, treating plantar warts is challenging. No single treatment is effective in most patients, treatments are often painful, and they are associated with a high recurrence rate. Although nearly 75 percent of warts can resolve spontaneously within two years, patients often seek treatment for cosmetic reasons and pain. Many studies have examined the use of vitamin D compounds (calcipotriol) and 5-fluorouracil in wart patients separately or in combination with other drugs, but only one recent case report that tested the combination of these two showed very positive efficacy results \[5, 6\]. To date, no clinical trial has evaluated the combination of calcipotriol and 5-fluorouracil. Additionally, given that common current treatments such as cryotherapy are painful for children, achieving an effective, pain-free intervention is necessary. This study aims to evaluate the efficacy and side effects of the combination of 5-fluorouracil and calcipotriol in children (ages 4 to 18) with palmar and plantar warts in a randomized, double-blind, placebo-controlled clinical trial.

The goal of this study is to evaluate Effectiveness and safety of Spartina® (Tirzepatide) in male or female participants with obesity and overweight. The main questions which are aimed to be answered: 1. Is Spartina® (Tirzepatide) effective in the treatment of obesity and overweight? 2. Is Spartina® (Tirzepatide) safe in the treatment of obesity and overweight? In this study, there is no comparison group. Participants receive Spartina® (Tirzepatide)

Diabetes management presents a complex clinical scenario marked by several challenges, especially in chronic kidney failure. These include navigating potential drug interactions between oral antidiabetic therapies and other agents. Furthermore, these patients may experience various adverse drug effects, such as lactic acidosis, electrolyte abnormalities such as hypomagnesemia, fluid retention, and lipid derangements, which can further augment overall morbidity. Consequently, many patients receive insulin. However, prolonged intensive insulin therapy may be linked to several adverse outcomes, including an increased risk of hypoglycemia and weight gain. Hence, a common practice is to transition to medications commonly used other populations of patients. With their established benefits on glycemic control, cardiovascular health, renal benefits, and weight management, in conjunction with the aforementioned adverse effects associated with other oral antidiabetics agents, glucagon-like peptide-1 receptor agonists have emerged as an attractive therapeutic option for patients with kidney failure.

This study, called "ROSUBREAST", is a multicenter, double-blind, randomized clinical trial evaluating whether rosuvastatin (20 mg daily) can protect the heart in women with breast cancer receiving anthracycline-based chemotherapy. A total of 400 participants will be randomly assigned to receive either rosuvastatin or placebo for 12 months. The main goal is to determine whether rosuvastatin can prevent cancer treatment-related cardiac dysfunction (CTRCD), defined as a significant drop in heart pumping function. The study will also assess changes in cardiac strain, blood biomarkers, symptoms of heart failure, quality of life, and possible side effects.

Trans arterial chemoembolization (TACE) has emerged as a treatment option for chemotherapy-refractory diseases in Liver metastases. By delivering chemotherapy agents directly to the tumor site, TACE can maximize local drug concentrations and reduce systemic adverse reactions. Bevacizumab is a monoclonal antibody that functions as an angiogenesis inhibitor. It works by slowing the growth of new blood vessels by inhibiting vascular endothelial growth factor A (VEGF-A). The application of Bevacizumab during TACE has not been reported. In this study, we will evaluate the the overall survival (OS)、efficacy, and safety of the application of Bevacizumab during TACE in patients with Liver Metastases by designing an open, single-arm phase II clinical study.

Epidermolysis bullosa (EB) is a hereditary disease of skin tissues that causes painful bleeding blisters in the skin and mucous membrane. The prevalence of this disease is 1 in 50,000. The severity of the disease varies depending on the type of disease and may even lead to death. This disease is caused by a genetic mutation in keratin or collagen, and its incidence is the same in all men and women of different human races. In these patients, the skin becomes extremely fragile and peels off with the slightest scratch. Many blisters are one of the most obvious symptoms of this disease. The possibility of skin cancer in people suffering from this disease is more than others. Nowadays, the preference of cell therapy methods is to use biological products produced by cells such as extracellular vesicles and mitochondria instead of stem cells. The use of Extracellular vesicles and engineered EVs as messenger carriers can introduce a new treatment method based on cell products for skin regeneration and as an alternative to cell therapy. Therefore, in this study, EV.FV will be applied topically to patients.

The Computerized Registry of Patients with Venous Thromboembolism (RIETE) is a multidisciplinary Project initiated in march 2001 and consisting in obtaining an extensive data registry of consecutive patients with venous thromboembolism. The main objective is to provide information on the Internet to help physicians to improve their knowledge on the natural history of thromboembolic disease, particularly in those subgroups of patients who are usually not recruited in randomized clinical trials (pregnant women, elderly patients, disseminated cancer, severe renal insufficiency, patients with contraindications to anticoagulation therapy, extreme body weight, etc), with the purpose of decreasing mortality, frequency of thromboembolic recurrences as well as bleeding complications and arterial events. As an additional objective RIETE is also aimed to create predictive scores that help physicians to better identify patients with high risk of presenting some of these complications. The primary parameters recorded by the registry comprise details of each patient's clinical status, including any coexisting or underlying conditions, and the type, dose, duration and outcome (during the first 3 months of therapy) of antithrombotic treatment. Study endpoints are clinically recognized (and objectively confirmed) recurrences of VTE, major and minor bleeding complications, and death.

Chemotherapy is an essential component of breast cancer treatment. Frequent intravenous injections may lead to phlebitis and limited venous access, therefore implantable venous ports are increasingly used. The choice of port placement side in breast cancer patients is controversial, especially when mastectomy or radiotherapy is planned. This retrospective cohort study compares one-year patency, complications (infection, thrombosis, skin necrosis), and functional outcomes of ports implanted via the right internal jugular vein in patients with right versus left breast cancer.

This study examines the demographic, clinical, and laboratory characteristics of patients with diabetic foot ulcers admitted to 5 Azar Hospital, Gorgan, in 2024. By analyzing factors such as Hb, WBC, HbA1C, ESR, and CRP in relation to ulcer severity, the study aims to identify predictors of outcomes and support more effective prevention and management strategies

This is a descriptive analytical study to investigate the prevalence and risk factors for pancreatitis after Endoscopic Ultrasonography-guided Fine Needle Biopsy (EUS-FNB) in patients at Shariati Hospital in Tehran. The study aims to identify risk factors for post-FNB pancreatitis to improve clinical protocols, reduce complications and treatment costs, and increase diagnostic accuracy for pancreatic and biliary tract diseases. The study will collect demographic and clinical data from all eligible patients undergoing EUS-guided FNB during the study period. Amylase and lipase levels will be measured in all enrolled patients 24 hours post-procedure. Pancreatitis will be diagnosed based on abdominal pain and amylase or lipase levels exceeding three times the normal range 24 hours after the procedure. The outcomes will be independently adjudicated by an expert gastroenterologist not involved in the EUS procedures by reviewing participants' medical records. The consensus definition will be applied as a diagnostic framework (rather than a strict definition) so that the adjudicator can use their best judgment in cases that does not strictly satisfy the criteria. The patients will be contacted 24-72 h after the procedure to follow-up on any potential complications. The study plans to enroll at least 300 patients.
