Scope & Taxonomy

The LAI universe, defined

A Long-Acting Injectable (LAI) is not a keyword. Vectora defines the universe with one defensible rule — and holds the line where others blur it.

What qualifies as a LAI

Every asset in Vectora meets three cumulative criteria. Miss one, and it is out — regardless of how it is marketed.

  • 1Injectable route. IM, SC, slow IV, perineural, intra-articular, intra-tumoral, intravitreal, epidural. Not oral, not transdermal, not solid non-injectable implants.
  • 2A deliberate duration technology. Either a Drug Delivery System (the formulation releases the drug over time) or Half-Life Extension (the molecule is engineered to last). A long native half-life alone does not count.
  • 3Duration that breaks with daily dosing. Significantly longer than the indication's immediate-release standard, with a hard floor of ≥ 48 hours after a single dose.

Where others blur — and Vectora holds the line

Keyword tagging pulls in molecules that are long-acting for the wrong reasons. Vectora excludes them, on purpose:

  • Long-acting by mechanism, not technology. Bisphosphonates, botulinum toxin, native-long-half-life antibodies — the effect comes from the biological target, not a delivery or half-life technology.
  • Daily basal insulins. Lantus, Levemir, Tresiba carry real HLE chemistry — but act under 48h and are injected daily. Out. Only weekly-plus HLE insulins (e.g. insulin icodec) qualify.
  • Pure implants. A device-and-procedure story, not drug delivery. Captured only when they compete alongside a LAI — never as standalone assets.
  • Short or daily injectables. Below the 48-hour floor, however "sustained" the label sounds.
  • Vaccines, cell & gene therapy. Out by editorial scope — unless a DDS/HLE technology carries the payload. The test is always the source of the duration: engineered delivery, not the biology itself.

Calibrated to the clinic, not a blunt cutoff

"Long-acting" means something different in post-operative pain than in schizophrenia. The rule is relative to each indication's standard of care — with the 48-hour floor underneath.
