Of course, the transformational Unilever announcement is expected in the next few months - and we all know that. So that pretty much underpins the current level. Even without an announcement, there'll be speculative buying beforehand. This is the AI summary of when the announcement will take place, do such trials usually complete on time and are they usually successful? - bottom line is the odds are in APTA's favour:
Unilever planned to start on-person functionality studies in the second half of 2024. Follow-on work likely includes further in-vivo testing (which typically means testing in human subjects or under conditions mimicking real use).
According to the companies’ statements, the overall project is anticipated to be completed within “about two years” from mid-2024 — which would point toward completion sometime in 2026 (assuming no major delays).
🚀 What this means
There is no specific official announcement yet giving a firm end-date for the human testing phase or reporting final results to the public.
Based on the public statements, the program was expected to progress through 2024 and onto on-person trials, and then ideally complete by around 2026 if everything stays on track.
⚠️ Notes
Unilever does not routinely share detailed schedules for internal R&D trials unless there’s a product launch announcement or regulatory filing — so exact finish dates for human testing aren’t publicly posted yet.
The timeline above is based mainly on statements from Aptamer Group about when stages were planned and how long they expect the overall project to take.
Do they usually finish on schedule?
Roughly:
~50–60% finish close to the originally planned timeline
~30–40% experience delays
~10% get paused, redesigned, or quietly dropped
Why delays happen (even when the science is solid):
Recruitment takes longer than expected (finding the right participants)
Variability in human biology (sweat rate, microbiome, lifestyle)
Results are ambiguous → extra study rounds needed
Safety, irritation, or performance thresholds aren’t met
Internal business decisions (budget, reprioritisation, reformulation)
For deodorants specifically, timelines are moderately predictable, but anything involving novel actives or biology-targeting tech (like Optimer binders) has a higher chance of slippage.
✅ Are on-person trials usually “successful”?
Depends how you define success.
If “success” means:
“Works well enough to move forward”
~60–70% of trials meet minimum performance & safety criteria
If “success” means:
“Ready for commercial launch with no major changes”
Only ~30–40%
Most projects land in the middle:
The product works, but not consistently enough
Or it works for some people, not others
Or it works but needs reformulation (dose, delivery, pairing with other actives)
This is especially true for odour-control tech targeting enzymes or bacteria, where:
Individual microbiomes vary wildly
Performance can differ by gender, climate, stress, di
