What Did the Enovid Clinical Trials Actually Show? Phase 2 and 3 Results Explained

Who developed Enovid, and why it was studied

Enovid was developed by SaNOtize Research & Development, a Canadian biotech company. Its co-founders, Dr. Gilly Regev and Dr. Chris Miller, built the formulation around nitric oxide — a molecule the human body produces naturally as part of its own defense system. Because a nasal-delivered nitric oxide technology (NONS) was new, SaNOtize ran a series of clinical trials to understand how it performs in the nose.

What the Phase 2 and Phase 3 studies looked at

Research on the formulation has been carried out in the UK, India and Thailand and published in peer-reviewed journals, including the Journal of Infection and The Lancet Regional Health – Southeast Asia. In India the same spray is a prescription product called FabiSpray™, distributed by Glenmark. The common thread across these studies was a focus on viral load in the nasal cavity during the early days of infection — how much virus was measurable, and how that changed over time.

What the studies established — and what they didn't

It's important to read this evidence responsibly. The trials measured specific outcomes in specific populations under controlled protocols. They are not the same thing as a blanket claim that the product prevents any illness. One point that is frequently misunderstood: SaNOtize's US prevention trial was terminated because of recruitment challenges, not because of a safety problem or a failure to work. Skeptics sometimes cite the termination as if it were negative evidence — it wasn't.

In the United States, NoWonder™ is sold as a cosmetic nasal cleanser, and we make no drug or disease-prevention claims for it. The value of the clinical record is that it exists, it's peer-reviewed, and it's public — you can read it yourself.

Where to read the primary sources

Rather than take anyone's summary at face value, we keep the study list — with journals and links — on our clinical data page. If you want to understand the science behind Enovid nasal spray, that's the best starting point.

Enovid™ is a registered medical device in Israel, Germany, South Africa and several Asian markets. In the United States the identical formulation is sold as NoWonder™, a cosmetic nasal cleanser, and no drug or disease-prevention claims are made for it. Any studies referenced here were conducted with Enovid™ or FabiSpray™ outside the United States.
