Serina Therapeutics is a small biotechnology company focused on developing new treatments for neurological diseases, particularly Parkinson's disease. Its core technology is a drug delivery platform called POZ, which is designed to make existing drugs work better and last longer in the body. The company is in early-stage research and does not yet sell any approved products.

Serina makes no commercial revenue today and funds its work through grants, partnerships, and capital raises — typical for a pre-revenue biotech. It operates primarily in the United States and is a very small company with a market cap near zero, meaning it carries significant financial risk. The main growth driver would be advancing its lead drug candidate through clinical trials and eventually gaining regulatory approval, but the main risk is that it could run out of funding before reaching that milestone.
