Leadership change disclosed; administrative filing treatment is standard.

The company reports a change in its commercial leadership with the departure of its Chief Commercial Officer. Such transitions can affect commercial execution, but the notice here is limited to the fact of departure and the furnishing of a press release.

The filing also clarifies technical treatment: the 6-K (excluding the exhibit) is incorporated into multiple registration statements, while the press release is furnished, not filed. This preserves disclosure without attaching Section 18 liability to the exhibit.
