Description: Serina Therapeutics Inc is a clinical-stage biotechnology company developing a pipeline of wholly-owned drug product candidates to treat neurological diseases and pain. Serina's POZ Platform delivery technology is engineered to provide control in drug loading and more precision in the rate of release of attached drugs, enabling the potential of certain challenging small molecules, while addressing the limitations of polyethylene glycol (PEG) and other biocompatible polymers. The company has one reportable segment relating to the research and development of its POZ platform. The segment derives its revenues from Grant revenue. Its main product candidate, SER-252 for advanced Parkinson's disease, is anticipated to enter clinical trials.

How positions resolve to the securities master. FIGI_COMPOSITE is exact identifier equality — both sides got the FIGI from Bloomberg. TICKER is a narrow fallback used only where the master row carries no FIGI at all (2,389 rows do not, disproportionately Irish-domiciled US listings like LIN and ACN). Roughly 22% of all positions resolve to the master.

Classification

classification.v_security_classification

Asset class: Equity
Sector: Health Care
Industry: Pharmaceuticals
Source: LLMunreviewed
Self-reported confidence: 0.95
Model: deepseek
Rationale: SIC 2834 indicates pharmaceutical preparations, so the security is an equity in the healthcare sector.

Classifications are unreviewed model output. All 5,771 assignments carry source = LLM and is_reviewed = false. Confidence is the model’s own estimate and is not calibrated — it clustered at 0.90–0.98 across the whole first pass, including rows that later proved wrong. Use it to order a review queue, not as a probability. Two share classes of one issuer can disagree.

Not linked to a fund series.

Either this is not a fund, or it is one the SEC share-class snapshot cannot reach — commodity trusts and notes have no series ID at all.
