SeagenSeagen (Nasdaq:SGEN) has tapped a law firm to lead an investigation into its CEO Clay Siegall, who was charged with misdemeanor assault against his wife on April 23.

Siegall maintains his innocence.

A police report related to the incident reported that Siegall’s wife called 911 after he allegedly forced her to the ground.

Siegall was later charged with fourth-degree domestic violence, according to police reports obtained by Endpoints News.

Siegall’s wife also filed a temporary restraining order against him. The couple is going through divorce proceedings.

The police report alleges that Siegall (61) pushed his wife Nellie to the ground and dragged her along the floor, causing bruises and abrasions.

Founded in 1997, Bothell, Washington-based Seagen is a leading biotechnology company focused on antibody-drug conjugates. Its 2021 revenues were $1.6 billion.

Siegall is a co-founder of the company.

Following the recent allegations, Seagen has installed its chief medical officer, Dr. Roger Dansey, to assume the role of interim CEO. Dansey has worked at the company since 2018.

Siegall’s future role at the company is uncertain.

Nancy Simonian, chair of Seagen’s nominating and corporate governance committee, said the company is “treating these allegations with the utmost seriousness.”

“At this time, the facts are still uncertain, and our decisions will be guided by the outcome of our investigation,” Simonian continued.
