Directional Versus Nondirectional DBS for ET
This will be a single center (OHSU) proof of concept trial to demonstrate that directional deep brain stimulation (DBS) creates a larger therapeutic window for the treatment of essential tremor (ET), effectively treats ET, and minimizes effects on speech, gait and balance compared to nondirectional DBS.
Correlation Between Intraoperative Tourniquet Use and Limb pH, Functional Measures and Patient-reported Outcomes After Ankle Fracture Surgery
This study aims to 1) characterize skeletal muscle pH during/after tourniquet use and 2) investigate any relationship between intraoperative tourniquet use and postoperative functional measures and patient-reported outcomes.
BLOCK-SAH - PPF-Block for Post-SAH Headache
BLOCK-SAH is a phase II, multicenter, randomized, double-blinded, placebo-controlled clinical trial with a sequential parallel comparison design (SPCD) of bilateral pterygopalatine fossa (PPF) injections with 20mg ropivacaine + 4mg dexamethasone (active, PPF-block) compared to saline (placebo) for headache in survivors of aneurysmal subarachnoid hemorrhage (SAH), while monitoring intracranial arterial mean …
Transcranial Magnetic Stimulation in Progressive Supranuclear Palsy
The objective of this proposal is to investigate the effect of non-invasive repetitive cerebellar transcranial magnetic stimulation (rTMS) on motor control in progressive supranuclear (PSP). The central hypothesis is that augmenting cerebellar inhibition via cerebellar rTMS will decrease postural instability in patients with PSP. We will use functional near infrared …
Testing the Addition of Herceptin Hylecta or Phesgo to the Usual Chemotherapy for HER2 Positive Endometrial Serous Carcinoma or Carcinosarcoma
This phase III trial tests whether adding trastuzumab and hyaluronidase-oysk (Herceptin Hylecta [TM]) or pertuzumab, trastuzumab and hyaluronidase-zzxf (Phesgo [TM]) to the usual chemotherapy (paclitaxel and carboplatin) works to shrink tumors in patients with HER2 positive endometrial cancer. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that …
A Study With Tovorafenib (DAY101) as a Treatment Option for Progressive, Relapsed, or Refractory Langerhans Cell Histiocytosis
This phase II trial tests the safety, side effects, best dose and activity of tovorafenib (DAY101) in treating patients with Langerhans cell histiocytosis that is growing, spreading, or getting worse (progressive), has come back (relapsed) after previous treatment, or does not respond to therapy (refractory). Langerhans cell histiocytosis is a …
Feasibility of FMISO in Brain Tumors
This phase II trial studies how well ¹⁸F- fluoromisonidazole (FMISO) works with positron emission tomography (PET)/magnetic resonance imaging (MRI) in assessing participants with malignant (cancerous) brain tumors. FMISO provides information about the oxygen levels in a tumor, which may affect how the tumor behaves. PET/MRI imaging produces images of the …
A Study to Compare the Administration of Encorafenib + Binimetinib + Nivolumab Versus Ipilimumab + Nivolumab in BRAF-V600 Mutant Melanoma With Brain Metastases
This phase II trial compares the effect of encorafenib, binimetinib, and nivolumab versus ipilimumab and nivolumab in treating patients with BRAF- V600 mutant melanoma that has spread to the brain (brain metastases). Encorafenib and binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for …
Study in Parkinson Disease of Exercise
This study is a Phase 3 multi-site, randomized, evaluator-masked, study of endurance treadmill exercise on changes in the Movement Disorder Society-Unified Parkinson Disease Rating Scale (MDS-UPDRS) Part III score at 12 months among persons with early stage Parkinson disease. 370 participants will be randomly assigned to 2 groups: 1)60-65% HRmax …
Phase I Study of ANK-101 in Advanced Solid Tumors
This is a Phase 1, multicenter, open-label dose escalation study to determine the safety and tolerability of intratumoral (IT) injection of ANK-101 in participants with advanced solid tumors who have progressed during or after receiving standard of care (SOC) therapy or who will not benefit from such therapy. The study …
