Material uncertainty over going concern
We draw attention to Note 1.2 in the financial statements, which indicates that the Company is dependent on securing future funding from investors in order to continue as a going concern. There is no certainty that such funding will be available. The Directors expect that the Company will have sufficient resources to continue its research and development activities for at least 12 months from the date of approval of these financial statements. However, the events and conditions described in Note 1.2 may cast significant doubt on the Company's ability to continue as a going concern. Our opinion is not modified in respect of this matter.

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
