Going-concern doubt — flagged Aug 6, 2026

Substantial doubt about the company's ability to continue as a going concern.

“However, given the risks associated with these potential strategic or financing opportunities, they are not deemed probable for purposes of the going concern assessment and do not alleviate the substantial doubt about our ability to continue as a going concern. There can be no assurance that we will be able to generate sufficient net product revenues or obtain additional capital on favorable terms or at all.”
