NCT ID NCT04365101

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tested a new therapy called CYNK-001, which uses natural killer cells from the placenta to fight COVID-19. It enrolled only 7 adults with moderate COVID-19. The study was terminated early, so we have limited information on safety and effectiveness.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

CYNK-001 (natural killer cells from placenta)

What this could lead to

If successful, this could point toward a cell-based therapy to help the immune system fight COVID-19.

What could go wrong

This was a very early, small trial (only 7 people) that was terminated early, so results are limited. Cell therapies can have side effects like infusion reactions or immune system overactivation.
