Clay Siegall resigned as Seagen’s president, CEO and a board member effective May 15, 2022, after the company disclosed that he had taken leave following an alleged domestic violence incident at his home. Seagen said Siegall denied the allegations and that its independent board committee was investigating. The company said his resignation was not based on findings from that investigation.
What Seagen announced
In a May 5, 2022, filing, Seagen said it was aware of an alleged domestic violence incident that had occurred recently at Siegall’s home. The company said he denied the allegations and had told it he was engaged in a divorce. Seagen also announced that Siegall was taking a leave of absence and that chief medical officer Roger Dansey would serve as interim CEO.
The board formed a committee of independent directors to investigate and retained an outside law firm to assist. In a May 16 filing, Seagen said the investigation was ongoing.
What was reported about the arrest
Contemporaneous news reports, citing police records, said Siegall was arrested on April 23, 2022, and faced a charge of fourth-degree domestic violence, a gross misdemeanor. An arrest and charge are not proof of guilt. Seagen described the matter as an allegation, and its filing recorded Siegall’s denial.

When the resignation took effect—and what it did not establish
Siegall’s resignation from the roles of president, CEO and director took effect May 15, 2022. Seagen’s May 16 filing said the departure was mutually agreed and explicitly stated that it was not based on findings from the company’s investigation. The filing also said Dansey would remain interim CEO while the company searched for a permanent successor.
Seagen’s 2023 proxy statement said the independent committee’s investigation continued. The public materials cited here do not establish a final investigative finding.
