McDermott Advised Vivet Therapeutics on the Sale of its Equity to Pfizer


McDermott Will & Emery advised Vivet Therapeutics, a gene therapy biotechnology company dedicated to the development of hereditary liver disorders, in the acquisition by the American group Pfizer of a 15% equity interest in Vivet. The transaction included an exclusive option to acquire all outstanding shares. Pfizer and Vivet will collaborate in the development of VTX-801, Vivet’s proprietary treatment for Wilson disease.

Pfizer may exercise its option to acquire 100% of Vivet following the company’s delivery of certain data from the Phase I/II clinical trial for VTX-801.
