Key Terms

crispr, in vivo, phase 3

3 terms

crispr technical

"focused on revolutionizing medicine leveraging CRISPR gene editing"

CRISPR is a gene‑editing technology that works like precise molecular scissors to change DNA in living cells. For investors, it matters because it can speed development of new therapies, lower research costs, and create valuable intellectual property, but it also carries scientific, regulatory, ethical, and commercial risks that can strongly affect the value and prospects of companies working with the technology.

in vivo technical

"commercialize our first potential in vivo gene editing product"

In vivo describes tests or experiments performed inside a living organism, such as an animal or human, to observe how a drug, device or biological process behaves in a real, functioning body. Investors care because in vivo results reveal safety, effectiveness and possible side effects that lab tests cannot, much like road-testing a prototype car in traffic rather than only on a bench — outcomes can strongly influence regulatory approval, clinical success and a company’s valuation.

phase 3 medical

"advance our Phase 3 clinical trials in transthyretin amyloidosis"

Phase 3 is the late-stage clinical testing step for a new drug or medical treatment, where the product is given to large groups of patients to confirm effectiveness, monitor side effects, and compare it to standard care. Successful Phase 3 results are often the final scientific hurdle before regulators decide on approval and market launch—like passing a final exam before graduation—and can sharply change a company's valuation and future revenue prospects.
