NCT01904851
XLPAD is an observational study designed to evaluate the effectiveness and use of stent and non-stent based therapies among PAD patients. The study will create a registry that will include entry of procedural and clinical follow-up information into an online data collection software, REDCAP.Data available since Jan 1 2005 will be included in the registry, until 14,000 patients have been included. The primary objectives of this observational registry study are to: 1. Compare stent and non-stent based outcomes defined as a composite of symptom driven target vessel revascularization (TVR), unplanned surgical revascularization of the target limb and need for target limb amputation through 12 months post-index procedure (Primary efficacy endpoint) 2. Compare stent and non-stent based outcomes defined as a composite of causes such as: death, myocardial infarction (MI), stroke, peri-procedural complications, target vessel revascularization (TVR) and unplanned surgical revascularization/amputation of the target limb through 12 months (Primary safety endpoint) 3. Compare stent and non-stent based change in walking distance, Rutherford category and/or ankle- brachial index (ABI) at 12 months compared to baseline (Primary clinical improvement endpoint) Approximately 14,000patients will be enrolled at approximately 60 sites worldwide. Enrollment in the observational study will be monitored in an effort to achieve at least 20% (and no more than 80%) of the population receiving stents as the initial treatment strategy. Follow-up visits by sites will be reported at 6 and 12 months after index procedure to collect data on treatment patterns and effectiveness, and outcomes. The follow-up procedures are not mandated by the registry protocol. Each site will be encouraged to enter follow-up information derived from clinically indicated follow-up visits. All events post-index procedure till the 7th month will be reported under the 6 month follow-up form and subsequent follow-up till the 13th month post-procedure will be entered on the 12 month follow-up form. Patient management and treatment decisions are at the discretion of the care team per routine clinical practice. The procedural aspects (including selection of stent type or non-stent based treatments) and follow-up are not mandated by the registry and will be up to the discretion of the operator and/or based upon the practice dictated by the clinical care of the patient. Therefore the study poses minimal risk to the patient.

NCT00066690
RATIONALE: Estrogen can stimulate the growth of breast tumor cells. Ovarian function suppression combined with hormone therapy using tamoxifen or exemestane may fight breast cancer by reducing the production of estrogen. It is not yet known whether suppression of ovarian function plus either tamoxifen or exemestane is more effective than tamoxifen alone in preventing the recurrence of hormone-responsive breast cancer. PURPOSE: This randomized phase III trial studies ovarian suppression with either tamoxifen or exemestane to see how well they work compared to tamoxifen alone in treating premenopausal women who have undergone surgery for hormone-responsive breast cancer.

NCT07078383
The Goal of this Clinical Study is to evaluate the safety and effectiveness of the Rapidlink device in the repair or replacement of the supra-aortic vessels during open surgical repair of aortic disease affecting the thoracic aorta. This study will collect information on patients who are already having surgery to repair their aorta and who will have Rapidlink device implanted into one or more of the aortic arch vessels. The first 32 subjects enrolled will undergo left subclavian artery repair or replacement, only, with the Rapidlink device. After the 32nd subject, enrollment will proceed to include subjects undergoing any supra-aortic vessel (i.e., left subclavian artery, left common carotid artery, and/or innominate artery) repair or replacement with the Rapidlink device in a planned surgery. After the 32nd subject is enrolled in the main group, up to 30 subjects will undergo supra-aortic vessel (i.e., left subclavian artery, left common carotid artery, and/or innominate artery) repair or replacement with the Rapidlink device in an emergency setting. Data will be collected before, during and after surgery including recovery at discharge, 30 days, 6 months, 1 and 2 years after the surgery.

Approximately 75 participants with active IgG4-RD will be enrolled in the overall program, 12 in Part 1 and 63 in Part 2. Randomization in Part 2: 2 to 1, with approximately forty-two participants randomized to elotuzumab plus prednisone taper, and twenty-one participants randomized to placebo for elotuzumab plus prednisone taper. The total duration of participation for each participant in this trial will be 48 weeks (11 months).
NCT03898180
The purpose of this study is to evaluate the efficacy and safety of lenvatinib (MK-7902/E7080) in combination with pembrolizumab (MK-3475) in the treatment of cisplatin-ineligible participants with a Programmed Cell Death-Ligand 1 (PD-L1) Combined Positive Score (CPS) ≥10, or in participants ineligible for any platinum-containing chemotherapy regardless of CPS, with advanced/unresectable or metastatic urothelial carcinoma (UC). The primary hypotheses for this study are that: 1. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR), and 2. Pembrolizumab + lenvatinib is superior to pembrolizumab + placebo with respect to Overall Survival (OS). Based on recommendation of the external Data Monitoring Committee (eDMC), Amendment 3 (effective: September \[Sep\]-24-2021) was implemented to unblind the study and discontinue lenvatinib and placebo treatment. The eDMC was then disbanded. With Amendment 4 (effective: December-5-2022) second course pembrolizumab will no longer be offered. Any participant receiving second course pembrolizumab treatment prior to initiation of Amendment 4 will be able to complete treatment as planned. Study participation will end after the final administration of pembrolizumab. Participants who either complete 35 administrations of pembrolizumab or discontinue pembrolizumab will discontinue from the study following the safety follow-up visit. AEs and spontaneously reported pregnancies will be reported and followed per protocol. The overall study ends when the last participant completes the last study-related contact or visit, withdraws from the study, or is lost to follow-up.
