A former Genentech principal scientist and her husband were convicted of stealing trade secrets and providing the information to a Taiwanese company, which then parlayed the purloined data to reach a $101 million partnership with Sanofi (SNY) to develop medicines.

Xanthe Lam, who worked for Genentech from 1986 through 2017, helped to siphon information about four drugs — the Avastin, Rituxan, and Herceptin cancer treatments, as well as the Pulmozyme cystic fibrosis medication — to JHL Biotech, which was founded by former Genentech employees to develop biosimilar versions of these and other drugs, according to court documents.


The information contained different processes and procedures for formulating, testing, and manufacturing the medicines, including drug substance and product specifications, as well as analytical methods, according to documents filed at the time that she and her husband, Allen Lam, were indicted in 2018. Her husband worked as a consultant to JHL.
