Von Willebrand Disease

The EMPOWER trial is a pilot multi-center, placebo-controlled (normal saline), double-blind (patient and outcome assessor), crossover, 2-year randomized trial in female outpatients with von Willebrand disease (VWD) and heavy menstrual bleeding to determine trial feasibility and viability, and explore assay sensitivity of the proposed efficacy clinical outcomes for a definitive randomized controlled trial. For the first treatment period, patients will be randomized to receive either plasma derived von Willebrand factor:Factor VIII (pdVWF:FVIII) concentrate (plus standard of care) or placebo (plus standard of care) for VWD-associated heavy menstrual bleeding for 4 cycles, crossing over to the comparator treatment during the second treatment period. The first treatment period will be followed by a 1 cycle washout period when no study-based treatment will be delivered. The main purpose of the pilot will be to evaluate viability and feasibility of the trial design, as well as to explore assay sensitivity to inform determination of the primary efficacy outcome for the definitive randomized trial which will evaluate the effect of prophylaxis with pdVWF:FVIII concentrate compared with placebo on HMB in women with VWD. A secondary objective is to conduct a preliminary assessment of the effect on clinical outcomes of 2-3 doses of prophylaxis with pdVWF:FVIII concentrate when provided on the first 4 days of menstruation compared with placebo.

This is a first-in-human (FIH), Phase 1/2, open-label, dose escalation, safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and efficacy study of HMB-002 in participants with VWD. Part A of the study involves a single ascending dose (SAD) design to establish safety, tolerability, PK, and PD effect. In Part B of the study, the safety and tolerability of repeat dosing will be established prior to cohort expansion to explore efficacy.

This is a prospective, screening study in participants with confirmed Type 1 VWD according to diagnostic guidelines. Participants with confirmed Type 1 VWD and associated bleeding symptoms will be enrolled. The study may also be opened to participants with Type 2 and Type 3 VWD with Sponsor approval. Up to a total of 200 participants may be enrolled in the study. The study includes screening, a baseline evaluation, and an approximately 4 month observation period which will include every other week telemedicine check-ins (to monitor bleed diary entries and bleeding event treatments. There will be an optional extension to the observation period of up to a total of 12 months for participants wishing to continue.

The objective of this clinical investigation is to evaluate the safety and efficacy of ETHIZIA to control minimal, mild, or moderate soft tissue bleeding during open surgery when compared to SURGICEL Original in the percentage of cases achieving hemostasis at 3 minutes after product application, and without re-bleeding up to 10 minutes after application.

The main aim of the study is to check effectiveness, side effects, and tolerability of vonicog alfa (recombinant von Willebrand factor \[rVWF\]), with or without ADVATE, in the treatment and control of nonsurgical bleeding events in pediatric participants (less than (\<)18 years of age) with severe hereditary von Willebrand disease (VWD). The participants will be treated with vonicog alfa for 12-18 months. Their von Willebrand Disease will be treated by their doctor according to their doctor's usual clinical practice. During the study, participants will be followed up at clinics or over telephone calls.

This is a Phase III, multicenter, open-label clinical study designed to evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of emicizumab prophylaxis in participants aged 1 month and above, who have been diagnosed with Type 3 von Willebrand disease (VWD). Participants on prior standard of care (SOC) on-demand therapy will be assessed via a randomized comparison (Arm A - emicizumab prophylaxis and Arm B - continuation of SOC on-demand therapy), while participants on prior SOC prophylactic therapy (Arm C - emicizumab prophylaxis) will be assessed via intra-participant analysis with data obtained from the preceding non-interventional study (NIS), WP45335 (NCT06883240).

The goal of this clinical trial is to evaluate the safety, tolerability, and recommended Phase 2 Dose (RP2D) of KLN-1010 in patients with relapsed or refractory multiple myeloma.

This is a Phase I/II, open-label multicenter study to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of anti-GPRC5D CAR-T cell product (OriCAR-017) in subjects with relapsed/refractory multiple myeloma". The study will consist of a Phase I dose escalation stage involving three doses as a single IV infusion) with up to 18 evaluable subjects and a dose expansion stage with 10-15 evaluable subjects, followed by a Phase II stage with up to 48 evaluable subjects.

This non-interventional study (NIS) is designed to collect information on the effectiveness and safety of treatment received in routine clinical care, as well as measure the health-related quality of life (HRQoL) of participants with Type 3 von Willebrand disease (VWD) receiving prophylactic therapy per local standard of care (SOC) over an observation period of at least 24 weeks.

This is a prospective, multicenter, open-label, randomized trial comparing OAC with no OAC (1:1 ratio) in patients who develop new-onset POAF after CABG. The primary effectiveness endpoint is the composite of death, ischemic stroke, transient ischemic attack (TIA), myocardial infarction (MI), systemic arterial thromboembolism or venous thromboembolism (VTE) at 90 days after randomization. The primary safety endpoint is BARC (Bleeding Academic Research Consortium) grade 3 or 5 bleeding at 90 days after randomization. The overall intent is to evaluate the trade-off in prevention of thromboembolic events versus an increase in bleeding. Patients will be randomly assigned to the following treatment strategies: * OAC-based strategy (experimental arm): OAC with vitamin K antagonist (VKA) with international normalized ratio (INR) target 2-3 or any approved direct oral anticoagulant (apixaban, rivaroxaban, edoxaban or dabigatran) in addition to background antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor) * Antiplatelet-only strategy (control arm): single antiplatelet therapy with aspirin 75-325mg once-daily or a P2Y12-inhibitor (clopidogrel or ticagrelor) The protocol-specified duration of anticoagulation is 90 days. Patients, who are randomized to the control arm and develop recurrent AF after 30 days, may be crossed-over to an OAC. Accrual is expected to take 60 months. Study follow-up visits will be performed at 90 days and phone follow-up at days 30, 60, and 180 days. Data for patients enrolled in the registry will be ascertained from the local clinical site via a review of medical records. The baseline risk profile of registry patients (i.e., patients eligible but unwilling to be randomized) will be analyzed and compared to that of patients randomized in the trial. The usage of anticoagulant and antiplatelet therapies in the registry population overall and baseline CHA2DS2-VASC ischemic stroke risk score will also be determined. Up to 500 patients will also be offered the option to participate in a digital health substudy which includes a wearable heart rhythm monitor device for 30 days post discharge.
