About OvaScience, Inc.
OvaScience, Inc. was a fertility company that tried to improve in vitro fertilization outcomes using egg precursor cells. Its scientific founders had published research suggesting that women carry egg precursor cells in the ovaries that could be harnessed. The company developed the AUGMENT treatment, which aimed to boost egg quality with mitochondria taken from a patient's own precursor cells. It also worked on OvaPrime and OvaTure, programs intended to create or mature eggs.
OvaScience was founded in 2011 in the Boston area with backing from well-known life science investors. It became a public company in 2012 and its shares later listed on Nasdaq under the symbol OVAS. Early enthusiasm pushed its market value above $1 billion. AUGMENT was offered in fertility clinics in several countries outside the United States.
Clinical results proved disappointing, and AUGMENT uptake was slow. The company went through leadership changes, layoffs and repeated restructurings from 2015 onward. By 2017 it had dropped AUGMENT and was searching for strategic alternatives. Its cash balance became its most important asset.
In August 2018 OvaScience agreed to a reverse merger with Millendo Therapeutics, a private Ann Arbor, Michigan company developing treatments for endocrine diseases. The deal closed on December 7, 2018 after a 1-for-15 reverse split, leaving former OvaScience holders with about 16.5 percent of the combined company. The renamed Millendo Therapeutics began trading as MLND on December 10, 2018. In 2021 Millendo merged with Tempest Therapeutics, and the same listed entity now trades as TPST.
