BEIJING – The ongoing trade war between the U.S. and China has helped put the biotechnology field on the U.S. foreign investment restriction list, causing a chilling effect on the market. With the amount of Chinese money entering the U.S. biotech sector dropping sharply, many believe it is the U.S. that is taking the hit.

The U.S. FDA has granted breakthrough device designation to Laboratory for Advanced Medicine Inc. (LAM) for its liquid biopsy blood test for the detection of liver cancer. The test, which analyzes the DNA methylation pattern of cell-free DNA (cfDNA), is designed to detect the presence of hepatocellular cancer as early as stage 1, with both high specificity and sensitivity.

The FDA's September 2018 draft guidance for considerations of benefit-risk determinations for several device types, including PMAs, said that the agency "intends" to hold an advisory committee hearing if the FDA has any questions about the post-market data generated by the accompanying post-approval study. The final guidance pulls back on that language, but only slightly, stating that the agency "generally expects" to hold an advisory hearing in this circumstance, a difference in language that may or may not translate to a difference in function.

Edwards Lifesciences Corp.'s buy of Cas Medical Systems Inc. (Casmed) this spring appears to have borne fruit. The Irvine, Calif.-based company reported that the U.S. FDA has granted clearance for a smart cable enabling compatibility between the company's Foresight tissue oximetry (brain oxygenation) sensors and the Hemosphere advanced monitoring platform.

BEIJING – The trade war has escalated. On Aug. 23, China announced retaliatory tariffs on $75 billion of U.S. exports, 10 days after the U.S. slapped the same amount on $300 billion of Chinese goods. Once again, the med-tech sector is neck deep in this tariff tit-for-tat.
