NO CLASS HAS YET BEEN CERTIFIED IN THE ABOVE ACTION. UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY COUNSEL UNLESS YOU RETAIN ONE. YOU MAY RETAIN COUNSEL OF YOUR CHOICE. YOU MAY ALSO REMAIN AN ABSENT CLASS MEMBER AND DO NOTHING AT THIS POINT. AN INVESTOR’S ABILITY TO SHARE IN ANY POTENTIAL FUTURE RECOVERY IS NOT DEPENDENT UPON SERVING AS LEAD PLAINTIFF.

According to the lawsuit, the materials supporting Gossamer’s IPO, and certain of the Company’s post-IPO public filings, may have misled investors or otherwise omitted material facts relevant to Gossamer’s GB001 drug and its related clinical trials and studies. Then, on December 16, 2019, Novartis announced that it was terminating the development of its DP2 antagonist for asthma after it failed a pair of phase 3 clinical trials. As a result, Gossamer’s common stock dropped by approximately 37% in one day. The stock has continued to plummet. When the true details entered the market, the lawsuit claims that investors suffered damages.

A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than June 2, 2020. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.
