Stem cell therapy heals injured mouse brain


Animal study examines method for restoring brain cells killed by stroke or other neurological diseasesPR Brain

Scientists and clinicians have long dreamed of helping the injured brain repair itself by creating new neurons, and an innovative NIH-funded study published today in Nature Medicine may bring this goal much closer to reality. A team of researchers has developed a therapeutic technique that dramatically increases the production of nerve cells in mice with stroke-induced brain damage.

ZZ Biotech Announces Phase 2 Trial with 3K3A-APC in Stroke

ZZ Biotech Announces Phase 2 Trial with 3K3A-APC in Stroke; Funds Will Be Provided by NIH and Broadview Ventures

HOUSTON, April 22, 2014—ZZ Biotech today announced that the National Institutes of Health will support a multicenter Phase 2 clinical trial of its experimental drug, 3K3A-APC, in patients suffering from acute ischemic stroke.

The Phase 2 study will evaluate safety, tolerability and activity of ZZ Biotech’s 3K3A-APC when given after tissue plasminogen activator, or tPA, in patients who have experienced moderately severe ischemic stroke. The drug will be given intravenously as a 15-minute infusion every 12 hours for up to five treatments, and four dose levels will be evaluated. About 100 participants, ages 18 to 80, will be followed for 90 days.

Experimental stroke therapeutic developed at Keck Medicine of USC also shows promise for people with Lou Gehrig’s disease (ALS)

New research finds vascular damage in mice with ALS contributes to early development of the neurodegenerative disease, while repairing damage delays disease progression

LOS ANGELES, March 3, 2014Keck School of Medicine of USC neuroscientists have unlocked a piece of the puzzle in the fight against Lou Gehrig’s disease, a debilitating neurological disorder that robs people of their motor skills. Their findings appear in the March 3, 2014, online edition of the Proceedings of the National Academy of Sciences of the United States of America, the official scientific journal of the U.S. National Academy of Sciences.

ZZ Biotech Initiates Phase 1 Study with 3K3A-APC for the Treatment of Acute Ischemic Stroke

HOUSTON, Texas, August 8, 2012—ZZ Biotech, LLC today announced that it has commenced dosing healthy volunteers in a Phase 1 clinical study with 3K3A-APC, a recombinant variant of human activated protein C (APC), being developed for the treatment of acute ischemic stroke.

The Phase 1 study is a randomized, double-blind, placebo-controlled, single-center trial that will investigate the safety and pharmacokinetics of single and multiple ascending doses of 3K3A-APC in healthy adult volunteers. Approximately 62 eligible adult subjects will be assigned sequentially to 1 of 10 cohorts, at successively higher single doses, followed by successively higher multiple doses. Results of the study are anticipated in the first quarter of 2013.
