Going-concern doubt
— flagged Aug 11, 2026
Substantial doubt about the company's ability to continue as a going concern.
“Management has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that these financial statements are issued. The Company's ability to continue as a going concern is dependent upon the Company's ability to raise additional debt and equity capital or secure a potential license or strategic relationship that can help fund its clinical development activities. There can be no assurance that such capital will be available in sufficient amounts or on terms acceptable to the Company. These factors raise substantial doubt about the Company's ability to continue as a going concern.”View the 10-Q filed Aug 11, 2026
