VOLUNTARY ANNOUNCEMENT PRESENTATION OF PRECLINICAL STUDIES OF ANTI-CGC ANTIBODY (hC2) AT SID ANNUAL MEETING 2026
Regulatory Filings Classification · 30% confidence The document is a voluntary corporate announcement regarding the presentation of preclinical study results at a scientific conference. It contains no financial statements, no management changes, no voting results, and is not an investor deck or earnings release. It simply notifies the market of a scientific poster presentation and related abstract link. This does not fit any specific category (e.g., 10-K, IR, ER, IP, etc.), so it falls under the general Regulatory Filings (RNS) fallback category.
