Stroke clinical trials at UC Davis

Study Objective is to establish the feasibility and safety of the NOVIS Transcarotid Neuroprotection System when used for the transcarotid intervention of patients that have a failed transfemoral endovascular therapy in the case of anterior circulation strokes due to large vessel embolic occlusions.

Primary Aim: To determine if apixaban is superior to aspirin for prevention of the composite outcome of any stroke (hemorrhagic or ischemic) or death from any cause in patients with recent ICH and atrial fibrillation (AF). Secondary Aim: To determine if apixaban, compared with aspirin, results in better functional outcomes as measured by the modified Rankin Scale.

The primary objective of Part 1 of the study is to determine if BIIB093 improves functional outcome at Day 90 as measured by the modified Rankin Scale (mRS) when compared with placebo in participants with Large Hemispheric Infarction (LHI). The secondary objectives of Part 1 of the study are to determine if BIIB093 improves overall survival at Day 90 when compared with placebo, if BIIB093 improves functional outcome at Day 90 on the mRS dichotomized 0-4 vs. 5-6 when compared with placebo, if BIIB093 reduces midline shift at 72 hours (or at time of decompressive craniectomy [DC] or comfort measures only [CMO], if earlier) when compared with placebo, and to evaluate the safety and tolerability of BIIB093 in participants with LHI. The objectives of Part 2 of the study are to evaluate long-term disability following LHI, to evaluate long-term outcome measures of clinical function, quality of life, and healthcare utilization, and to assess the safety of BIIB093 in subjects with LHI during the follow-up period.

The current project investigates a method called paired associative stimulation (PAS) which is known to influence nervous system function through a process called neuroplasticity. Here the investigators will target function of the ankle plantarflexor muscles because they are critically important to walking. The investigators will study adults who have walking dysfunction resulting from stroke. The study will test three ways of delivering PAS targeted towards brain-muscle connections serving the ankle plantarflexors. The overall goal is to improve functioning of the plantarflexors. The investigators believe that improving plantarflexor function will increase the likelihood of positive effects from gait retraining programs for people post-stroke. Participants will experience all three PAS methods in separate sessions. The investigators will compare differences in the size of these effects to identify the optimal method for delivery of PAS to the ankle plantarflexors. This study is a preliminary step to help us design a better clinical trial of combined PAS and gait retraining.

A Phase 3 study to examine the safety and effectiveness of the allogeneic, adult stem cell investigational product, MultiStem, in adults who have suffered an acute ischemic stroke in the previous 18-36 hours.
