Sarepta has shown that golodirsen will increase dystrophin levels, but has not completed studies to demonstrate animprovement in muscle function.

Announced Research Updates

Published Research Updates
In the 465 patient, Phase II/III ZEUS trial, 64.7% of patients treated with injectable fosfomycin achieved clinical cure and microbiologic eradication that was non-inferior to the 54.5% overall success achieved with piperacillin-tazobactam in patients with urinary tract infection (cUTI) or acute pyelonephritis (AP). The original ZEUS data was calculated based on the 2015 FDA Guidance for the development of antibiotics to treat cUTI/AP. Nabriva announced that in a reassessment of the ZEUS data based on the 2018 FDA Guidance, which reduced the microbial eradication threshold, 78.6% for patients in the fosfomycin group achieved overall success compared to 33.3% of patients in the piperacillin-tazobactam group, in patients with piperacillin-tazobactam-resistant infections. In patients with piperacillin-tazobactam-susceptible pathogens, the overall success rate was 64.7% for patients in the fosfomycin group and 56.7% for patients in the piperacillin-tazobactam group.
In the 6,545 patient, Phase III trial, Norvartis’ serelaxinwas no different than placebo in preventing further decompensation over the first 5 days (6.9% vs 7.7%) or in reducing CV death at 6-months (8.7% vs 8.9%).
In a 38 patient, Phase II trial, treatment with Peregrine Pharmaceuticals’bavituximab plus sorafenib resulted in a median time to progression of 6.7 months in patients with advanced hepatocellular carcinoma.
