3 months in and triple agonist is still the thing I get wrong

Trial Data Well Actually ×7 Long Haul ×3 Receipts ×2

Reporting in. 3 months in and triple agonist is still the thing I get wrong.

The numbers the title promised, since a headline without them is worthless: 3 months. Everything below is context for those.

Stopped at a low step because there was no reason to go further and no data to tell me what further would do.

Where the evidence actually stands, since every thread here assumes a different answer.

Phase 2 reported a large mean body weight change at 48 weeks across a few hundred participants with a slow, protocol-driven escalation. The effect size was striking. The confidence intervals were wide, the population was small, and the duration was under a year.

Phase 3 is running. Until it reports, everything else — including the ranking arguments this board loves — is extrapolation from a small study. That is not a criticism of the compound; it is a description of the evidence.

Research-use-only material is not approved for human use and nothing here should be read as a recommendation to use it.

Standing reminder in every thread here: unapproved compound, research material is not for human use, nothing on this board is medical advice.

Is that the 48-week figure or an earlier readout?

u/naomi_erdogan-36 points·1 year ago

the escalation is where most of the reported trouble sits

u/vito_beaulieu1 point·1 year ago

small trial, big effect, wide error bars

This. The phase 2 result was genuinely large and it was also 48 weeks in a few hundred people.

This is the sentence the rest of the board should read first. Phase 2 is not a label.

The phase 2 readout ran to 48 weeks in a few hundred participants with a slow escalation. Both the size and the duration matter when people quote the headline number.

u/nikhil_asante764 points·1 year ago

Went up slowly, deliberately, because everything on this board says the escalation is where trouble lives. Uneventful so far and I am not going to pretend that is a finding.

It is a triple agonist at the GLP-1, GIP and glucagon receptors. The glucagon arm is the genuinely novel component and it is the one with the least human outcome data behind it.

It is a triple agonist at the GLP-1, GIP and glucagon receptors.

fabio_lehtinen is right about the escalation being the variable. It explains most of the difficult reports here.

not approved anywhere, which is the single most important fact in this board

u/sena_teixeira346 points·1 year ago

Small fix — three receptors, not two. GLP-1, GIP and glucagon, and the third one is the reason this compound gets its own board.

u/reflux_report108 points·1 year ago

the TRIUMPH programme is still running, so anything definitive is premature

u/trialwatch_theotrial nerd296 points·1 year ago

The thing that surprised me was how much of the discussion here is inference rather than measurement.

replysharereportpermalink
u/rekha_vestergaard94 points·1 year ago

Same read. The energy-expenditure mechanism is the interesting bit and it is not established in humans at scale.

replysharereportpermalink
u/kofi_balogun0 points·1 year ago

Same read.

Disagree with this specific inference. A 48-week readout does not tell you the shape of the curve after it.

u/yannick_salinasOP1 point·1 year ago

Which phase 2 arm are you quoting, and at what week?

replysharereportpermalink
u/jarno_cabrera324 points·1 year ago

Phase 2 estimates effect and finds a dose range. Phase 3 estimates it precisely in a bigger population and catches what phase 2 was too small to see. Treating them as the same tier of evidence is the recurring error here.

u/honest_syringe_202589 points·1 year ago

Watched heart rate on a wearable across twelve weeks because the threads said to. It moved a little and I have no idea whether that means anything.

replysharereportpermalink
u/careful_gradient_again20 points·1 year ago

Read the phase 2 paper twice before ordering anything. Recommend that to anyone in this board: the error bars are the interesting part.

u/kofi_balogun211 points·1 year ago·edited

Are you comparing against phase 3 numbers for something else? They are not comparable.

replysharereportpermalink
u/placebo_arm_pam64 points·1 year ago

phase 2 data only, and people quote it like it is a label

replysharereportpermalink
u/andres_restrepo33 points·1 year ago

Right, and it bears repeating that nothing here is approved anywhere and research material is not for human use.

replysharereportpermalink
u/titration_marshalmod · c/semaglutide25 points·1 year ago

Increases in heart rate have been reported across this receptor class. The magnitude and clinical significance are exactly what phase 3 is powered to establish.

replysharereportpermalink
u/rosa_almeida100 points·1 year ago

Yes — the comparison threads are apples to oranges and they generate more heat than anything else here.

About c/retatrutide

Retatrutide: GIP/GLP-1/glucagon triple agonism, the TRIUMPH programme, and the fact that most people discussing it are handling research-grade material with no human-use approval anywhere. Dose-response, heart-rate signal, and the unusually steep phase-2 weight curves get argued about here weekly.
