Clinical trials

Pulmonary rehabilitation (PR) is a key non-pharmacological intervention for patients with chronic obstructive pulmonary disease (COPD), yet it remains underutilized, particularly among patients living in peripheral areas due to limited access, travel distance, and logistical barriers. Tele-pulmonary rehabilitation (TPR) has the potential to improve access to care, but its feasibility and effectiveness as a group-based intervention have not been well established. The aim of this study is to evaluate whether a group-based TPR program can improve treatment initiation and adherence compared to usual care, defined as referral to standard PR, among COPD patients living in peripheral areas. In addition, the study will assess the effect of the intervention on COPD exacerbations, symptom burden, quality of life, and patient satisfaction. This is a prospective randomized controlled trial that will enroll patients with COPD who are eligible for PR according to the Israeli health basket criteria and have not participated in PR in the past year. Participants will be randomly assigned to one of two groups: (1) referral to standard PR (control group), or (2) participation in a 12-week, twice-weekly, group-based TPR program delivered remotely via a dedicated application and video sessions (intervention group).

Pulmonary rehabilitation is a key treatment for lung diseases, but many patients struggle to attend sessions due to travel distances, physical limitations, or logistical barriers. The purpose of this study is to evaluate whether a tele-pulmonary rehabilitation (TPR) program can improve the rates of treatment initiation and adherence among patients with chronic lung diseases compared to traditional, center-based pulmonary rehabilitation. Additionally, the study will assess improvements in quality of life, physical symptoms, and safety in both groups. This study will enroll 90 patients from two medical centers in Israel (Tel Aviv and Barzilai). Participants will be randomly assigned to one of two groups: 1. The control group will receive usual care with a referral by a pulmonologist to standard pulmonary rehabilitation at a medical center. 2. The intervention group will participate in a supervised remote tele-rehabilitation program using a dedicated application and remote monitoring.

This prospective randomized controlled trial evaluates whether a specialized "COPD flare-up clinic service" improves outcomes in patients following an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Patients presenting to the emergency department with AECOPD and discharged or hospitalized will be randomized 1:1 to either structured follow-up in a dedicated flare-up clinic or standard follow-up by scheduled telephone interviews. The researches hypothesize that structured follow-up in a specialized clinic will reduce recurrent exacerbations, optimize long-term COPD management, and improve patients' quality of life compared to standard care.

Asthma exacerbations leading to emergency department visits or hospitalization are associated with a high risk of recurrent exacerbations, poor disease control, and increased healthcare utilization in the months following discharge. Early specialist follow-up during this vulnerable transition period remains limited, and many patients do not receive optimized long-term asthma management. The purpose of this study is to evaluate whether a structured remote asthma clinic intervention initiated shortly after hospital discharge can reduce recurrent exacerbations and improve asthma-related outcomes compared to standard community care. This prospective randomized study will enroll 220 adult patients (18-75 years) presenting to the emergency department at Tel Aviv Sourasky Medical Center with an asthma exacerbation. Participants will be randomly assigned to one of two groups: 1. Intervention group - will undergo two structured remote pulmonology follow-up visits via secure video consultation within 7-21 days and 5 months after discharge, including treatment optimization, inhaler technique assessment, and self-management education. 2. Control group - will continue standard community care without additional intervention. All participants will complete scheduled follow-up assessments over 12 months, including evaluation of exacerbations, asthma control, healthcare utilization, and medication use.

This phase II, open-label, single-arm, study investigates the clinical benefit of everolimus combined with endocrine therapy (ET) in hormone receptor-positive (HR+), metastatic breast cancer (MBC) patients who progressed on prior PI3K inhibitor therapy (+ ET). The trial aims to determine if sequential inhibition of the PI3K/AKT/mTORC1 pathway retains efficacy post-PI3K inhibitor resistance, hypothesizing that everolimus will demonstrate a response rate exceeding the historical 9.5% observed in the BOLERO2 trial.

This is a Phase 1, single-center, open-label study to evaluate the safety of CLS-015 in combination with anti-CD19 CAR-T therapy in patients with large B-cell lymphoma. The goal is to improve clinical response by reversing the negative effects of NETs on immune function and CAR-T cells.

This is a pilot study designed to assess the feasibility, adherence, and preliminary effects of a 6-week home-based gait training intervention using the Walking Tall mobile app in individuals with Parkinson's disease. The app delivers rhythmic auditory cues and motivational verbal prompts to promote gait improvements. Primary outcomes include daily walking duration and step count measured via wearable sensors; secondary outcomes include gait speed, balance, self-reported confidence, and usability.

We will seek consent from participants to use the data and biospecimens collected according study protocol to address additional research questions for MGUS, SMM, MM, and other conditions. Our overarching hypothesis is that early detection of MGUS/SMM in a high- risk population, along with the comprehensive characterization of genomic/epigenomic and microenvironmental/immune regulators of disease progression will lead to strategies that intercept disease progression and improve survival.

Breast cancer is the most common malignancy among women worldwide. Triple-negative breast cancer (TNBC), defined by the lack of estrogen receptor, progesterone receptor, and HER2 expression, comprises approximately 15% of all breast cancers and is the most aggressive subtype, associated with a higher risk of early recurrence and death compared to other breast cancer subtypes. Neoadjuvant chemotherapy (NACT), administered before definitive surgery, is the standard of care for stage II-III TNBC (eTNBC), and pathological complete response (pCR), defined as the absence of invasive cancer in the breast and lymph nodes at surgery, following neoadjuvant systemic therapy, is strongly associated with improved survival in this population. In the pivotal phase 3 KEYNOTE-522 study, the addition of Pembrolizumab (an immune checkpoint inhibitor (ICI), a PD-1 inhibitor) to NACT significantly improved both pCR rates and survival in patients with eTNBC , establishing a new standard of care for these patients. The KEYNOTE-522 regimen is a five-drug regimen administered in two distinct phases: in the first phase, Paclitaxel and Carboplatin are administered with Pembrolizumab for four cycles (TCa+P) and in the second phase, Adriamycin and Cyclophosphamide are administered with Pembrolizumab for an additional four cycles (AC+P). This regimen carries a high toxicity burden, particularly due to anthracyclines, which are associated with late cardiotoxicity and increased risk of therapy-related leukemias. Many patients, however, achieve an excellent response after only the first phase of treatment (paclitaxel-carboplatin + pembrolizumab), raising the question of whether treatment can be safely de-escalated in selected responders. Emerging evidence from the NeoPACT and NEO-N studies suggests that pCR rates of 55-58% can be achieved with taxane-carboplatin-pembrolizumab regimen, even in the absence of anthracyclines. Moreover, the recently published TRAIN-3 study in HER2+ breast cancer demonstrated that radiologic complete response on MRI (MRI-CR) strongly correlates with pCR in hormone receptor-negative disease, with 87% concordance. Building on this rationale, we propose a prospective, investigator-initiated, multicenter, phase II clinical trial in Israel to evaluate the feasibility and efficacy of MRI-guided de-escalation of NACT plus immunotherapy in patients with eTNBC. All enrolled patients will receive four cycles (12 weeks) of paclitaxel-carboplatin with pembrolizumab (TCa+P), followed by breast MRI to assess treatment response. Patients achieving MRI-CR will proceed directly to surgery, omitting the second phase of anthracycline-containing chemotherapy (AC+P). Patients with radiologic residual disease (MRI-RD) will complete the full KEYNOTE-522 regimen. Adjuvant therapy, including pembrolizumab continuation and/or additional chemotherapy, will be administered based on pathological findings and physician and patient discretion. The primary endpoint is pCR rate among patients who achieve MRI-CR and undergo early surgery. The trial uses a Simon's two-stage optimal design and aims to test whether the observed pCR rate in MRI-CR patients exceeds the benchmark of 65% (based on KEYNOTE-522), with a target of 87% as suggested by TRAIN-3. Based on this approach, to reject the null hypothesis, a pathologic complete response (pCR) must be achieved in at least 22 of the 27 patients with MRI-CR who are referred to early surgery. Overall, Approximately 54 patients will be enrolled in the study to reach this goal. Key secondary endpoints include recurrence-free survival (RFS), overall survival (OS), and patient-reported quality of life (QoL). Patient-reported outcomes (PROs) will be collected longitudinally throughout the study to assess physical symptoms, psychological well-being, treatment-related toxicities, and functional recovery, helping to evaluate how treatment de-escalation impacts patient's experience. In addition, the study will prospectively collect blood samples for circulating tumor DNA (ctDNA) analysis, creating a unique biorepository of biologic material for translational research. ctDNA dynamics will be evaluated as a complementary biomarker to MRI, enabling assessment of early treatment response, molecular residual disease, and mechanisms of resistance. Samples will be collected at multiple timepoints, before treatment, during therapy, and prior to surgery, providing a rich dataset for future genomic, epigenetic, and immune profiling studies. This study represents an innovative, precision-driven approach to treatment de-escalation in eTNBC, with the potential to influence clinical practice and redefine the standard of care by identifying patients who can safely avoid anthracycline-based chemotherapy without compromising efficacy.

This is a multi-center, open-label, interventional clinical trial designed to evaluate the efficacy and safety of subcutaneous (SC) Mosunetuzumab as a first-line immunotherapy in patients with low tumor burden follicular lymphoma (LTB-FL), defined by the absence of GELF criteria. Eligible patients will undergo screening and, upon signing an Informed Consent Form, will receive their first dose of SC Mosunetuzumab. Mosunetuzumab is administered via SC injection without the need for mandatory hospitalization. The first cycle lasts 21 days, followed by subsequent 28-day cycles. In Cycle 1, Mosunetuzumab is given on Day 1 (5 mg), Day 8 (45 mg), and Day 15 (45 mg). From Cycle 2 onward, a single 45 mg dose is administered on Day 1 of each cycle. Treatment continues for up to 8 cycles (approximately 6 months). Patients will be monitored for disease status according to standard clinical practice. After completing active treatment, they will enter a post-treatment follow-up phase. Premedication with dexamethasone (20 mg) is mandatory in Cycle 1 and optional in later cycles. Acetaminophen and diphenhydramine may also be administered. All patients will continue study treatment as per the Schedule of Activities or until premature discontinuation. After treatment discontinuation, disease status assessments will occur approximately every 3 months for up to 24 months. During post-treatment follow-up, PET-CT scans for disease evaluation will be performed every 6 months, as applicable. Patients not under active follow-up will be contacted annually to collect data on disease status and survival. Throughout the trial, the following data will be collected (as applicable): demographics and baseline characteristics (including sex, age, race, height, and weight), medical history, details of initial diagnosis and treatment history, concomitant medications, adverse events (AEs), serious adverse events (SAEs), disease response, and survival status.

One Anastomosis Gastric Bypass (OAGB) is the most common metabolic and bariatric surgery (MBS) in Israel, recognized for its effectiveness in achieving sustainable weight loss and mitigating obesity-related diseases. The metabolic outcomes of OAGB are significantly influenced by the length of the biliopancreatic limb (BPL). The objective of this study is to determine whether tailoring the BPL length to the total small bowel length (TSBL) results in more effective weight loss compared to patients undergoing OAGB with a fixed BPL of 180 cm. Efficacy and safety of this approach will also be evaluated, ensuring it does not lead to long-term morbidity or negatively impact patients' quality of life.

This study investigates the impact of perioperative inhibition of beta-adrenergic and COX-2 signaling in ovarian cancer patients undergoing debulking surgery. The trial aims to assess the feasibility, safety, and biological effects of a combination of propranolol and etodolac in reducing cancer metastasis and improving immune responses.

This study is testing how different types of protein - from red meat, legumes (like lentils and beans), or a mix of both - affect muscle strength, body composition, and metabolic health in older adults with obesity who are also at risk for sarcopenia (loss of muscle mass and function). Participants will follow a personalized weight loss diet with one high-protein meal each day that includes either red meat, legumes, or both, along with a home-based strength training program. The study will last three months and will include health assessments such as blood tests, muscle and fat measurements, and physical function tests. The goal is to find out which type of protein source is most helpful for improving strength, reducing body fat, and supporting healthy aging.

This study is looking at how a medication called beta-blockers (metoprolol) affects patients with a heart attack (STEMI) who are in the cardiac intensive care unit. When patients are admitted to the unit, they will be randomly placed in one of two groups. One group will get the metoprolol medication, and the other will receive a placebo (a harmless pill that looks like the real medication). All other treatments will be the same for both groups. During the study, which is 72 hours long, patients will be monitored for blood pressure, heart rate, and lactate levels alterations. The main goal is to see if the medication helps improve patients condition or prevent it from getting worse. patients safety is a top priority, and if needed, the doctors can stop the study at any time if there are concerns.

This study investigates how well fentanyl is absorbed through the skin when delivered via a transdermal patch in critically ill surgical ICU patients. It compares hemodynamically stable patients with unstable patients who require vasopressors to maintain adequate blood pressure. Fentanyl blood levels will be measured over time to assess whether absorption is impaired in unstable patients. The goal is to determine whether transdermal fentanyl is a viable option for pain management in resource-limited ICUs or in situations where intravenous fentanyl is unavailable.

This prospective, non-interventional study aims to characterize the molecular and cellular mechanisms underlying the response and resistance of multiple myeloma (MM) patients to bispecific antibodies (BisAb) and CAR-T therapies. Conducted at the Tel Aviv Sourasky Medical Center, the study will enroll up to 200 MM patients aged 18 and older, who are candidates for BisAb, CAR-T, or other MM treatments. Bone marrow (4-6 mL) and peripheral blood (15-20 mL) samples will be collected before treatment and at predefined intervals post-treatment, including at disease relapse/progression. The study will analyze plasma cells and the tumor microenvironment (TME) using techniques such as flow cytometry (FACS), single-cell RNA sequencing, genomic DNA sequencing, and ELISA to assess soluble BCMA levels. Key objectives include identifying genetic and protein signatures predictive of treatment response, evaluating specific drug binding, and analyzing interactions between plasma cells and immune cells (e.g., T cells). Samples will be processed and stored at the study site, with data coded to ensure patient confidentiality. Results will inform personalized treatment strategies for MM patients. The study duration includes 5 years for sample collection, 1 year for data analysis, and up to 20 years for sample storage.

The role of dietary interventions in improving symptoms of multiple sclerosis (MS) is of high interest amongst patients and researchers, but data supporting this evidence are limited. Current evidence indicates that A higher Expanded Disability Status Scale (EDSS) score correlates with poor diet quality in patients with MS. Moreover, even though disease-modifying therapies (DMT) improve disease course and prognosis, MS patients report a lower quality of life (QoL) than people without illness. The Mediterranean diet (Med-Diet) is beneficial in preventing cardiovascular comorbidities, and outcomes of a decrease in inflammation processes are evident. Recent studies suggest that the Med-Diet might positively affect MS QoL, However, empirical evidence remains unclear, limiting the possibility of evidence-based nutritional recommendations. In the current study, we aim to investigate the effect of the Mediterranean diet on the quality of life of patients with MS. Methods: Randomized controlled trial among MS patients aged 18-70. The participants will be randomly assigned to two 1:1 ratio groups: The med-diet group and the control group (no intervention). The intervention will be carried out for six months with subsequent six-months follow-up. Nine nutrition sessions will be delivered to the intervention group by an expert registered clinical dietitian. Data will be collected at baseline, three months, six months, and 12 months, including the following: Demographic, Anthropometric measurements, Blood tests of complete blood count, chemistry, levels of vitamins D, and B12, CRP, neurofilaments light chain (NfL), Grip strength, Biochemical analysis for fatty acid composition in membranes of red blood cells (RBC) and HPLC analysis of carotenoid concentration. Patients will complete questionnaires for multiple sclerosis quality of life-54 (MSQoL-54), Patient Health Questionnaire (PHQ-9), Fatigue Severity Scale Questionnaire (FSS) and will undergo clinical evaluation for expanded disability status scales (EDSS) and Symbol Digit Modalities Test (SDMT). Dietary analysis and Med-Diet adherence will be validated by the Israeli Mediterranean diet screener (I-MEDAS) and by Food diaries. Calculated sample size: To achieve a mean difference of 10 points in the MSQoL-54 questionnaire and 80% power, a sample of 77 participants per group is needed. Considering a 5% drop-off, 81 participants per group are needed, and overall, 162 participants. Expected results: this study will highlight the effect of the Med-Diet dietary pattern on MS quality of life, MS symptoms, and its underlying mechanism, to enable evidence-based nutritional recommendations for MS patients Importance to Medicine: MS patients suffer from a decrease in QoL. Hence, physicians, researchers, and patients seek nutritional approaches that may improve their condition. If proven beneficial, The Med diet, a dietary approach that has been proven to reduce the risk for major comorbidities and that can be sustained throughout life, has the potential to improve the condition of MS patients in crucial lifestyle aspects.

To develop a reliable and accurate clinician-reported outcome (ClinRO) measure (against a new and precise definition) and patient reported outcome (PRO) for use by clinicians and researchers to quantify the severity of Freezing of Gait (FOG).

The purpose of the researchers is to test whether the CancerenD24 index, an algorithm based on the quantitative value of CD24, CD11b, clinical and laboratory characteristics, developed in the laboratory can help in the early detection of a malignant disease in a population of healthy subjects.

This is a pilot study to compare premeal to postmeal dosing of ultra rapid lispro insulin (URLi) used in a MiniMed 780G system hybrid closed loop system. Subjects with type 1 diabetes mellitus (T1DM) already using a 780G hybrid closed loop system with URLi will be included. After signing a remote digital informed consent, a baseline record of the MiniMed 780G system will be downloaded from the Medtronic digital platform (Carelink system \[1\]) and subjects will be asked to fill an online questionnaire regarding their time of insulin dosing preferences and a 3-day online food diary \[2\]. During the intervention period subjects will be asked to provide a bolus dose of insulin only at the end of meals for up to 4 weeks. During the last week of the intervention period, subjects will be asked to fill out a 3-day online food diary \[2\]. At the end of the intervention period- a Carelink report \[1\] will be collected remotely and subjects will be asked to fill again the online questionnaire regarding their time of dosing preferences. 1. Primary Objective: To assess the efficacy of premeal dosing to post-meal dosing on parameters of glycemic control as obtained from continuous glucose monitoring. 2. Secondary Objective: To assess patient dosing preferences and the effect of premeal dosing vs. post-meal dosing on patient reported outcomes Ref: 1. carelink.medtronic.eu 2. NutRatio.com.

To understand the mechanisms underlying the transfer from improvements in walking to improvements in mobility in daily life in people with PD; 4. To understand for whom treadmill training improves walking characteristics in the laboratory and for whom it does not, and to understand for whom treadmill training improves mobility in daily life and for whom it does not.

West Nile virus (WNV) is a mosquito-borne virus which in majority of cases causes only self-limited disease. Despite that, in minority of cases (\~0.5%) it can infect the brain and cause severe and even life-threatening disease (neuroinvasive disease). Recent study has shown that up to 40% of WNV patients who develop neuroinvasive disease, have antibodies against Interferons (anti-Type I interferon autoantibodies), which neutralizes interferons, and could explain the development of severe disease. The investigators therefore assume that early treatment with interferon beta (the type of interferon against which most patients do not have neutralizing antibodies) could prevent the development of severe neuroinvasive WNV disease.

Current guidelines mandate Helicobacter pylori (H. Pylori) eradication with 2-3 antibiotics for 14 days ,This may result in multiple side effects and in eradication of important bacterial species to human health, exposing humans to multiple disease conditions. Preservation of fecal microbiome prior to antibiotic therapy and auto-transplantation of the microbes post H. pylori eradication, will enable avoiding eradication of beneficial microbial populations and perhaps protect from consequent disease conditions.

Creutzfeldt-Jakob Disease (CJD) is the most common prion disease in humans causing a rapidly progressive neurological decline and dementia and is invariably fatal. The familial forms (genetic CJD, gCJD) are caused by mutations in the PRNP gene encoding for the prion protein (PrP). In Israel, there is a large cluster of gCJD cases, carriers of an E200K mutation in the PRNP gene, and therefore the largest population of at-risk individuals in the world. The mutation is not necessarily sufficient for the formation and accumulation of the pathological prion protein (PrPsc), suggesting that other, genetic and non-genetic factors affect the age at symptoms onset. Here we present the protocol of a cross-sectional and longitudinal natural history study of gCJD patients and first-degree relatives of gCJD patients, aiming to identify biological markers of preclinical CJD and risk factors for phenoconversion. The study includes two groups: Patients diagnosed with gCJD, and first-degree healthy relatives (both carriers and non-carriers of the E200K mutation in the PRNP gene) of patients diagnosed with gCJD. At baseline, and at the end of every year (for 4 years), healthy participants are invited for an "in-depth" visit, which includes a clinical evaluation, blood and urine collection, gait assessment, brain MRI, lumbar puncture, and Polysomnography sleep lab (PSG). At 6 months from baseline, and then halfway through each year, participants are invited for a "brief" visit, which includes a clinical evaluation, short cognitive assessment, and blood and urine collection. gCJD patients will be invited for one "in-depth" visit, similar to the baseline visit of healthy relatives.
