Aravive Inc.'s chief medical officer, Gail McIntyre, told BioWorld that a "very clever mechanism" designed by researchers at Stanford University helped lead to positive data from the first 12 patients of the ongoing phase Ib part of the phase Ib/II experiment with AVB-500 against notoriously hard-to-beat ovarian cancer.

Pfizer Inc. edged closer to Dermira Inc. in the rush for an approved treatment for atopic dermatitis (AD), a field dominated by Regeneron Pharmaceutical Inc.'s FDA-approved blockbuster, Dupixent (dupilumab), as Pfizer reported positive top-line results from a phase III trial evaluating the efficacy and safety of its oral JAK1 inhibitor, abrocitinib.

SAN FRANCISCO – Mitraclip from Abbott Park, Ill.-based Abbott Laboratories, has long been the only minimally invasive mitral valve repair device that's approved by the FDA. Edwards Lifesciences Corp., of Irvine, Calif., aims to challenge that dominance with its Pascal. This week at the Transcatheter Cardiovascular Therapeutics (TCT) conference, positive one-year data from the small CLASP study on Pascal were presented, offering a further glimpse of data for comparison.

Top-line results from Enanta Pharmaceuticals Inc.'s Argon-1 phase IIa study of EDP-305 for the treatment of nonalcoholic steatohepatitis (NASH) found one of the two doses of the drug tested met the study's primary endpoint, alanine aminotransferase (ALT) reduction at week 12, contributing further evidence for the drug's mechanism of action, farnesoid X receptor (FXR) agonism. But the non-biopsy study appears to have left investors without proof for something more even more valuable: a clear case for differentiation vs. FXR first-mover Ocaliva (obeticholic acid, Intercept Pharmaceuticals Inc.). Appearing to reflect the sentiment, Enanta's shares (NASDAQ:ENTA) fell 15.1% to $60.51 on Thursday.

LONDON – The first systematic review and meta-analysis of the accuracy of artificial intelligence in health care has concluded AI may be as good as clinicians in interpreting medical images, but it is hard to be sure because of the poor quality of published studies. Researchers at Birmingham University, U.K. considered 31,887 journal papers appearing between January 2012 and June 2019, of which 20,530 were screened. They found most were methodologically flawed.

Corvia Medical Inc. is enrolling patients in a 100-site multinational study of its Interatrial Shunt Device that will measure traditional heart failure endpoints as well as biosensor data transmitted to the cloud for analysis by Napier, Ill.-based Physiq's artificial intelligence analytics. The trial will evaluate Tewksbury, Mass.-based Corvia's device in heart failure with preserved and mid-range ejection fraction.

BOSTON – The FDA's Center for Device and Radiological Health (CDRH) released draft guidance on Monday aimed at encouraging the use of patient input in medical device clinical trials and helping sponsors understand how they can use patient engagement to improve the design and conduct of investigations.

Shares of San Diego-based Tocagen Inc. (NASDAQ:TOCA) fell 77.7% to 93 cents on Sept. 12, and further since, after its two-part immunotherapy for people with recurrent brain cancer failed to surpass standard of care on overall survival (OS), the primary endpoint of the company's phase III Toca 5 trial. Secondary endpoints in the registrational study were also missed, showing no meaningful difference between study arms.

HONG KONG – In one of the latest combination efforts against cancer, Kahr Medical Ltd. is teaming up with Switzerland's Basel-based Roche Holding AG to study the use of the former's lead program, DSP-10, in combination with the latter's PD-L1-blocking checkpoint inhibitor, Tecentriq (atezolizumab), in patients with advanced non-small-cell lung carcinoma refractory to checkpoint inhibitors.
