How does AbbVie's Boey, a newly approved botulinum neurotoxin serotype E, compare to other botulinum toxin products in t

What the evidence tells us about Boey versus other botulinum toxins

Boey (trenibotulinumtoxinE) is a first‑in‑class botulinum neurotoxin serotype E approved in Canada for treating glabellar lines – the frown lines between your eyebrows [1]. It is designed to work differently from the more common serotype A products (like Botox, Dysport, Xeomin, or Jeuveau) by kicking in faster and wearing off sooner [4][5][6][8].

Onset of action

In AbbVie’s pivotal studies, some patients noticed improvement as early as 8 hours after injection – the earliest time they could be checked. This rapid start is a key feature that sets Boey apart from most other neurotoxins. [1][2][8]

Duration of effect

Boey’s wrinkle‑smoothing lasts about 2–3 weeks [2][8]. AbbVie describes this as a shorter duration than what you’d expect from currently available botulinum toxin products [4][8]. (Because the evidence doesn’t contain head‑to‑head trials, we don’t have direct duration numbers for those other products here.)

Efficacy for glabellar lines

Boey was tested in two large Phase 3 studies that compared it against a placebo. The studies met every primary and secondary goal they set out to prove, with statistically significant improvement in glabellar line severity at day 7 (p < 0.0001). Improvement was measured using both the patients’ own assessments and investigator ratings on the Facial Wrinkle Scale (FWS). [3][9]

In plain terms, Boey demonstrated clear, meaningful smoothing of frown lines in the studies, with a quick onset and a short‑lived effect.

How it stacks up against other products – a direct comparison

• Differentiated profile: The manufacturer states that Boey’s rapid onset and short duration offer a different option compared to currently available neurotoxins [4]. This is the main comparison the evidence supports.
• No head‑to‑head data: The sources do not include head‑to‑head studies (e.g., Boey vs. Botox). Therefore, we cannot give exact numbers on how its efficacy or duration compares to specific brand‑name toxins.
• Context from another type E toxin: A separate clinical study of a different botulinum type E product (EB‑001) reported an 80 % response rate for glabellar frown lines [7]. That reinforces that type E toxins can work, but it is not a direct comparison with Boey.

Bottom line from the evidence

Boey is a serotype E neurotoxin with onset as early as 8 hours and a duration of 2–3 weeks. The manufacturer positions it as a fast‑acting, short‑lasting alternative to the traditional type A products, though direct comparative data are not included in these sources. [1][2][3][4][5][8][9]
