Study B7841007 is an open-label extension study to assess the long-term safety, tolerability, and efficacy of prophylaxis treatment with marstacimab in participants who did not require "Early Termination" from the Phase 3 Study B7841005 and from the Phase 3 Study B7841008. Study B7841005: approximately 145 adolescent and adult participants 12 to \<75 years of age with severe hemophilia A or moderately severe to severe hemophilia B (defined as FVIII activity \<1% or FIX activity ≤2%, respectively) with or without inhibitors are expected to be enrolled in Study B7841005 during which they will receive prophylaxis (defined as treatment by SC injection of marstacimab). Study B7841008: this is an ongoing Phase 3, open-label study in pediatric participants \<18 years of age with severe hemophilia A (FVIII Coagulation Factor Activity \<1%) or moderately severe to severe hemophilia B (FIX Coagulation Factor Activity ≤2%). A sequential approach will be used in enrolling at least 100 pediatric participants, at least 20 of which will be aged ≥12 to \<18 years and at least 80 participants will be aged ≥1 to \<12 years. At the start of study B7841008, the dosing and data available in adolescent and adult participants in Study B7841005 supported the initiation of B7841008 study in participants aged ≥12 to \<18 years. Subsequently, additional safety and efficacy data from adolescent participants in Study B7841005 became available for benefit/risk assessment in support of dosing participants aged ≥6 to \<12 years. Based on the positive benefit/risk assessment conducted by both internal Pfizer review and eDMC review, dosing of the ≥6 to \<12 years age group was initiated in June 2023 in B7841008 Study. Data from participants ≥6 years from B7841008 Study and Study B7841005 will support the dosing of participants aged ≥1 to \<6 years. All participants will be provided the prefilled pen (PFP) for administration of marstacimab in the study. Use of the prefilled syringe (PFS) will be permitted at the investigator's discretion for those participants who have difficulty with administration of the PFP. Additionally, participants will be provided the PFS for use in this study in countries where the PFS is anticipated to be the only presentation available commercially. An optional, open-label, single arm, substudy using the PFP was completed in the first 23 participants rolled over from Study B7841005 who agreed to participate in the substudy.

The study will use standardized objectives, inclusion/exclusion criteria and outcome measures across all countries participating in this study including GCC (Qatar, KSA), Mexico, CAMCAR (Costa Rica, Panama, Dominican Republic), Colombia, Argentina, Taiwan, and Egypt, and any other countries that may be included in the study, in order to facilitate a comparison and analysis across all countries included in this study.

The goal of this clinical trial is to learn whether an AI-powered carbohydrate counting educational platform can help parents of children with type 1 diabetes improve their carbohydrate counting skills and diabetes management. The study will include parents or primary caregivers of children aged 2-12 years with type 1 diabetes. The main questions it aims to answer are: * Is the AI-powered educational platform feasible, acceptable, and easy for parents to use? * Can the platform improve carbohydrate counting accuracy, parental confidence in diabetes management, and diabetes outcomes compared with usual education alone? Researchers will compare parents who receive access to the AI-powered carbohydrate counting educational platform plus usual diabetes education with parents who receive usual diabetes education alone to see whether the AI-supported approach provides additional benefits. Participants will: * Complete baseline assessments, including questionnaires and a carbohydrate counting test. * Be randomly assigned to either the AI-supported education group or the usual education group. * Use the assigned educational resources for 12 weeks. * Complete a follow-up assessment at 6 weeks and a final assessment at 12 weeks. * Provide information about their child's diabetes management, including HbA1c and glucose monitoring data. * Complete questionnaires about confidence, usability, and satisfaction with the educational support they receive. The AI platform is designed to provide educational support only and does not replace medical advice, insulin dosing decisions, or routine diabetes care provided by healthcare professionals.

This study will evaluate the efficacy and safety of inavolisib in combination with Phesgo (pertuzumab, trastuzumab, and rHuPH20 injection for subcutaneous use) compared with placebo in combination with Phesgo, as maintenance therapy, after induction therapy in participants with previously untreated HER2-positive advanced breast cancer (ABC).

This study will evaluate the efficacy and safety of plozasiran in approximately 288 adult participants with severe hypertriglyceridemia (SHTG) and history of at least two prior acute pancreatitis (AP) events not attributed to other etiologies, with at least one occurring within the last 12 months prior to screening. Eligible participants will be randomly assigned in a double-blind manner to either receive plozasiran 25 mg by subcutaneous (SC) injection every three months (Q3M) or matching placebo. Enrolled participants will be counseled to remain on the specified low-fat diet and background medications throughout the study. Following completion of the double-blind treatment period, or if the participant has a positively adjudicated AP event (whichever occurs first), participants will transition to the 12-month Open-Label Extension (OLE) treatment period receiving plozasiran 25 mg by SC injection Q3M.

Only the participants who complete double-blind treatment period (Part A) are eligible to continue to the LTE period. The duration of the LTE period (Part B) will be from the first-participant-in (FPI)-LTE (Part B) until the last participant who enters the LTE has completed 52 weeks. * Treatment duration: 52-week double-blind period (Part A); LTE period (Part B) from the (FPI until the last participant who enters the LTE has completed 52 weeks. * Visit frequency: Week visits based on the Schedule of Assessments.

Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy, with over 80,500 estimated new cases diagnosed in the United States in 20231. Diffuse large B-cell lymphoma (DLBCL) is the most frequent subtype of NHL, accounting for 30%-40% of cases2. DLBCL is an aggressive malignancy with heterogeneous biology and behavior. Disease risk stratification and treatment planning involve various patient and clinical characteristics (e.g., age, stage, and tumor bulk), prognostic indices (e.g., International Prognostic Index (IPI) score), and gene expression profiling. Patients typically present with nodal or extranodal disease, usually exhibiting rapid tumor growth and symptoms that are highly dependent upon the tumor localization. The diagnosis and subtyping of DLBCL have significantly advanced, from morphological assessment of tissue slide to numerous ancillary tests, including immunophenotyping performed by immunohistochemistry (IHC), cytogenetics, and detailed molecular testing to classify the disease based on cell of origin (COO). With the advent of novel therapeutic options, molecular subtyping of DLBCL at diagnosis is expected to allow prognostic stratification of patients into distinct subgroups. This stratification could provide a preclinical rationale for therapeutic targeting the involved pathways and paving the application of personalized treatment. DLBCL is a potentially curable disease with an overall 60-70% chance of achieving durable complete remission (CR) with the currently used standard first-line immunochemotherapy. However, 30-40% of patients are either refractory to first-line treatment or experience relapse and eventually will die of disease progression7. Although high-dose chemotherapy followed by autologous stem cell transplant (ASCT) is the recommended SOC for eligible patients in the second-line setting based on results from the pivotal PARMA study, real-world SOC in this setting remains less clearly defined. Patients not cured with ASCT or ineligible to ASCT or refractory to salvage chemotherapy may be considered for Chimeric Antigen Receptor (CAR) T cell therapy targeting CD1910. Although ASCT and CAR-T cell therapy offer patients an opportunity for durable remission, many patients may not be eligible for ASCT or CAR-T cell therapy or relapse after these treatments. In the last decade, the investigation of novel antigens, which can be targeted by immunotherapy and identified to eliminate malignant cells regardless of their molecular pathogenesis, has been constantly pursued. This study aims to address this need by examining the demographic, clinical characteristics, and treatment patterns and exploring access to novel therapies for diffuse large B-cell lymphoma (DLBCL) patients, both treatment naïve and relapsed/refractory patients, in the Middle East and Africa (MEA) region.

This study is conducted to confirm whether etavopivat works well at reducing the number of Vaso-occlusive crisis VOCs (sickle cell pain crises) caused by obstructions in blood vessels in adults and adolescents living with sickle cell disease. The study will also evaluate how well etavopivat can reduce the damage to different organs, improve your exercise tolerance and reduce fatigue in people with sickle cell disease.The participants will either get etavopivat or placebo. Which treatment the participants will get is decided by chance. Etavopivat is a new medicine and is currently being tested in other studies in addition to this one. The study will last for about 2 years.

Protocol Title: Protocol Title: The Effect of using Weighted Blanket on anxiety, stress, depression and comfort level among Patients with cancer undergoing intravenous (IV) anticancer therapy and its feasibility of use by nurses compared to routine care; a Randomized controlled study. Study Tools: VAS-A, ESAS-R, DASS-21 and comfort level scale will be used to study the patients' population. A survey will be used to assess the feasibility of using the weighted blankets on patients receiving IV anticancer therapy. Methodology: Consented patients will be stratified per gender then randomized to either ARM1: The interventional arm, Weighted blanket, or ARM2: The control arm, Standard of care. (Regular blanket). The weighted blanket will be administered in the two cycles of IV anticancer therapy for the interventional arm, exploring the temporal trajectory of anxiety, depression, and psychological distress, and investigating the potential of a weighted blanket intervention to mitigate these symptoms. The tools will be administered according to the study protocol. Day Care Unit nurses will be assessed on how feasible they think the blankets are for patients. Expected Outcome: WB is expected to reduce the anxiety in patients undergoing IV anticancer therapy and reduce the nurses' burden when caring for those patients.

Etavopivat is a new medicine under development for treating blood disorders like sickle cell disease and thalassaemia. Sickle cell disease and thalassaemia are inherited blood disorders that affect haemoglobin. Haemoglobin is the protein that carries oxygen through the body. This study is looking into how safe treatment with etavopivat is and how well it works over a long period of time. The study will last for up to 264 weeks, but it will end earlier if etavopivat is approved in the participant's country.

Cancer is becoming more common worldwide. In countries like the United States, cases of breast and colorectal cancer have increased in recent years. A similar pattern is seen in Oman, where breast cancer is the most common cancer among women, and colorectal cancer is the most common among men. As more people are diagnosed with cancer, there is a growing need for safe and effective cancer treatment. One important type of treatment is systemic anticancer therapy (SACT), which includes medications such as chemotherapy, immunotherapy, and targeted therapy. These treatments are powerful and can cause serious side effects if not given correctly. Because of this, nurses who administer these treatments need special knowledge and skills to ensure patient safety. This study aims to develop an online learning (e-learning) program to help nurses improve their knowledge, skills, and confidence in safely administering systemic anticancer therapy. The study will also evaluate whether this e-learning program is effective compared to routine education. The study will be conducted in two major cancer care centers in Oman: the National Oncology Centre at Royal Hospital and the Sultan Qaboos Comprehensive Cancer Care and Research Centre. Nurses working in oncology and hematology units in these centers will be invited to participate. Participants will be divided into two groups. One group will receive access to the e-learning program (intervention group), while the other group will continue with their usual training (control group). The assignment to these groups will be done randomly to ensure fairness. Before starting the program, all participants will complete a questionnaire to assess their current knowledge, attitude, and practices related to systemic anticancer therapy. They will also provide basic information such as their age, years of experience, and previous training. The e-learning program will be developed based on the learning needs of nurses and reviewed by experts in oncology to ensure accuracy and quality. Nurses in the intervention group will be given time to complete the online training. After the training period, all participants (both groups) will complete the same questionnaire again. This will help researchers compare the results before and after the training, as well as between the two groups, to see if the e-learning program made a difference. The study will also assess how satisfied the nurses are with the e-learning program, as learner satisfaction is important for the success of educational interventions. Participation in this study is voluntary. All participants will provide written informed consent before joining the study. They will be informed about the purpose of the study, what they need to do, and their right to withdraw at any time without any negative consequences. All information collected will be kept confidential and used only for research purposes. At the end of the study, nurses in the control group will also be given access to the e-learning program to ensure fairness. The results of this study are expected to show that the e-learning program improves nurses' knowledge, attitudes, and clinical practices in administering systemic anticancer therapy. This may help improve patient safety and the quality of cancer care in Oman.

This study aims to compare the effectiveness of 4mg and 8mg dexamethasone administered submucosally in reducing postoperative pain after dental implant surgery. Participants will be randomly assigned to receive either 4mg dexamethasone, 8mg dexamethasone, or a placebo (normal saline) at the surgical site. Later, postoperative pain will be assessed using a Visual Analog Scale at 6 hours after the surgery and daily for the next 6 days. Also the number of pain-relief tablets consumed after the surgery will be recorded. Preoperative anxiety will be assessed using Generalized Anxiety Disorder-7 (GAD-7) questionnaire to assess its association with postoperative pain scores. The results of this study will help determine the optimal dose of dexamethasone that is effective for postoperative pain control following dental implant surgery.

This randomized, single-blind, controlled clinical trial aims to evaluate the efficacy and safety of Aescin-based herbal extract (Reparil®) compared with Ibuprofen in managing postoperative sequelae following surgical removal of impacted mandibular third molars. A total of 100 participants aged 18-40 years will be enrolled at the Dental Center, Medical City Hospital for Military and Security Services (MCMSS), Al Khoud, Oman. Participants will be randomly assigned to receive either Reparil® (Aescin 20 mg, three times daily for five days) or Ibuprofen (400 mg, three times daily for five days) following standardized third molar extraction procedures. Postoperative outcomes including pain (VAS), facial swelling (3D facial scanner), and mouth opening (digital caliper) will be assessed preoperatively, on day 2, and day 7 post-surgery. The study aims to determine whether Aescin offers comparable analgesic and anti-edematous effects to Ibuprofen with fewer adverse events.

The purpose of this prospective registry is to characterize the natural history of ectonucleotide pyrophosphatase/phosphodiesterase1(ENPP1) Deficiency and the infantile-onset form of adenosine triphosphate (ATP) binding cassette transporter protein subfamily C member 6 (ABCC6) Deficiency longitudinally. The registry will prospectively gather information about the genetic, biochemical, physiological, anatomic, radiographic, and functional manifestations (including patient reported outcomes \[PROs\]) of each disease during routine, standard-of-care visits, with the aim of developing a comprehensive understanding of the burden of illness and progressive nature of the disease.

The study will test a new medicine, etavopivat, for sickle cell disease and see if it is safe and help-ful for participants with sickle cell disease who are at an increased risk of stroke. Participants will be divided into two cohorts depending on their transcranial doppler (TCD) ultrasound results and whether or not they receive hydroxyurea (medication that they may already be taking). In one cohort, participants with conditional transcranial doppler (TCD) or participants with abnormal TCD who are not able to receive hydroxyurea will be included. The study doctor will determine if the TCD result is conditional or abnormal. In another cohort, participants with conditional TCD or participants with abnormal TCD who are receiving a stable dose of hydroxyurea will be included. The study doctor will determine if the TCD result is conditional or abnormal. The participant will start a 52-week (1 year) treatment period. The participant will take 400 milligrams (mg) of etavopivat once a day for the 52 weeks. The dose of 400 mg will be taken as 2 tablets by mouth, each containing 200 mg of etavopivat. Etavopivat may be taken with or without food. Each dose should be taken with a glass of water. As part of the study, the participants will be asked to visit the clinic frequently. The participant will have the opportunity to participate in a 48-week optional extension treatment period. The optional extension treatment period will allow continued as-sessment of safety of etavopivat in paediatric patients. At the end of the study, if deemed appro-priate the participant, the caregiver, and the study doctor, the participant may be offered the op-portunity to participate in a separate study to continue receiving etavopivat. If/when this separate study becomes available, the participant may only transfer to the new study after completion of the 52-week primary treatment period and at any time during the 48-week optional extension treatment period.

INTRODUCTION: The study focuses on comparing the effectiveness of oral Bisoprolol, a beta-1 adrenergic receptor blocker, against intravenous Diltiazem, a calcium channel blocker, in treating rapid atrial fibrillation or flutter with rapid ventricular response in an emergency setting. This research aims to fill the gap in empirical evidence regarding the use of oral Bisoprolol for these conditions, potentially offering a convenient, evidence-based alternative for patient management in emergency departments where established protocols are lacking. METHOD: This study is a randomized controlled trial targeting patients who present to the emergency room with symptomatic atrial fibrillation or flutter and rapid ventricular response requiring intervention. Participants will be split into two groups and undergo continuous monitoring of vital signs and regular electrocardiograms to ensure safety and document any adverse effects. The primary focus is on patient safety while evaluating the efficacy of the treatments. AIM: Evaluate the efficacy and safety of oral bisoprolol in treating atrial fibrillation or atrial flutter with rapid ventricular response in an emergency department setting. PRIMARY OJECTIVES: The primary efficacy outcome will be evaluated by achieving a HR\<110 beats per minute or a decrease ≥20% of baseline HR at 60 minutes. The primary safety outcome measures are HR \< 60 bpm and SBP \< 95 mm Hg. SECONDARY OBJECTIVES: The use of Rescue medication, proportion of patients who required hospitalization, worsening of heart failure or pulmonary oedema, side effect of medication ( dizziness, headaches, gastrointestinal symptoms) PATEINT POPULATION: Adults (18 and older) presenting to the emergency department at Sultan Qaboos University Hospital with symptomatic atrial fibrillation or atrial flutter with rapid ventricular response requiring treatment. INTERVENTION: A single oral dose of 5 mg Bisoprolol (maximum dose of 5 mg) or a single intravenous dose of Diltiazem at 0.25 mg/kg (to a maximum dose of 30 mg). CLINICAL MEASURMENT: Heart rate recorded every 15 minutes up to the 90-minute mark, with a 12-lead ECG performed every 30 minutes. OUTCOME: For therapy to be considered effective, patients must achieve a ventricular rate ≤110/min or experience a drop-in ventricular rate of at least 20% at 60 minutes.

The high prevalence of delirium in hospitalized older adults, with significant associated morbidity and mortality, emphasize the need for effective prevention strategies. Limited trials have explored melatonin's potential in preventing delirium among patients admitted to general medical wards. Previous trials on melatonin's preventive role in medical wards had limitations, necessitating a robust, double-blinded, placebo-controlled design with a larger sample size. This randomized, double-blind study of melatonin versus placebo aims to investigate the efficacy of melatonin, a neurohormone regulating the sleep-wake cycle, in preventing delirium among medically hospitalized patients aged 65 or older. Given the high prevalence of delirium in this population and its association with adverse outcomes, the study seeks to contribute valuable insights into an effective preventive strategy.
