24.2% at 48 weeks vs 28.7% Phase 3 - what explains gap?

The 28.7% is company-reported, not peer-reviewed. I'd anchor on the 24.2% until full papers land.

The part people forget when they're comparing numbers: longer exposure and a different titration schedule probably explain a lot of that gap.

Efficacy estimand versus treatment policy can move obesity numbers a lot. If lots discontinued, estimand choice matters. Do we know dropout rates in those Phase 3 trials?

I looked at the completed CTgov entries after seeing them mentioned here. NCT05548231 enrolled 32 Chinese participants, NCT05931367 enrolled 445 with obesity/overweight and knee OA, and NCT06039826 enrolled 46 postmenopausal women.

None list headline weight results in the raw record. So I don't think they resolve the 24.2 vs 28.7 question.

The 445-person trial might have useful secondary data, but it's a different population. The 32-person one is tiny. The postmenopausal one is also small. I'd treat them as supporting slices, not the main efficacy story for now, especially without dose-level data.

That 445-person knee OA trial is the only one with enough n to say much, but it's a different population than the big Phase 3.

If 24.2% is efficacy estimand at 48 weeks, I want completers vs ITT side by side.

The thing I keep coming back to is the glucagon component. Retatrutide is a triple agonist, and if that third arm contributes to the weight effect, the difference might widen over longer trials.

But I can't verify that from these CTgov records. The 32-person Chinese trial won't answer it.

The 46-person postmenopausal trial probably won't either.

The 445-person knee OA trial might have more useful data, but that wasn't in the raw record I saw. Until we get the Phase 3 papers, I'm treating 28.7% as a ceiling, not a typical result.

A 4.5-point gap is smaller than my monthly water-weight swings, honestly.

Estimand can do a lot: all-randomized vs completers is often worth several points by itself.

Those 32-person CTgov arms are basically a pilot; one hyper-responder skews the whole average.

The part people forget when comparing programs: the support baked into Phase 3. Weekly check-ins, food logs, a dietitian — that stuff can easily add 4 points over a Phase 2 where folks just got a handout and were sent on their way.

Common surprise from those 48-week logs people keep — food, sleep, training, the whole boring spreadsheet: weeks 1-12 down about 9%, weeks 13-28 down 6%, then weeks 29-48 only 3%, because weekends got loose. Waist kept shrinking the whole time though. Worth knowing before comparing options: scale averages hide a lot.

My own 48-week number vs my month-3 number differs by 4 points and it's mostly whoosh timing, not estimands.

Waistband check beats the scale for me. Same 12 lbs down at week 16, but jeans went from a 38 to a 34 while the scale sat frozen for nine straight days mid-month.

So when I see a 4-point gap between two trials I assume measurement windows and water shifts, not some huge difference in how the thing actually behaves. Nobody's tape measure moves two inches overnight.

I'm the cautionary tale for weekend math. Ten weeks in I was logging 1,700-1,800 on weekdays, gym three mornings, 8k steps, and I went 199 to 184 and then just parked at 184 for a solid month. I blamed the medication.

Then I actually added up Friday night through Sunday: takeout, two beers, brunch, the whole thing was landing near 3,400 a day, which quietly erased about five days of weekday deficit every week. The fix wasn't dramatic.

I started eating protein first at every meal, roughly 30g at breakfast, which killed the 10am vending machine habit, and I stopped treating Saturday as a free day and started treating it as a normal day with one actual treat in it.

Weeks 14 to 22 went 184 to 171, about 1.6 a week, faster than my first ten weeks. The reversal I didn't expect was sleep: when the late meals stopped I was out by 10:30 instead of midnight, and the morning scale started moving again.

So whenever I see 24% vs 28%, I wonder how much of that gap is just how carefully people were counting three days a week.

I'll push back a bit: the 4.5-point gap might be less about trial design and more about who's still standing at week 48, which is the exact trap I fell into with my own spreadsheet. I logged 48 weeks and my all-weeks average was 41 lbs down; if I'd dropped the six travel weeks and two holiday weeks where I didn't weigh or log, that same stretch reads 46 lbs, a 12% loss instead of 10.6%.

Nothing about my body changed, I just picked a friendlier denominator. Retention works the same way, since the people who quit at week 20 because the food noise came roaring back aren't in the week-48 completers number.

That number is real, it's just answering a different question than 'what happens if I start.' What moved my own needle more than any of this reading was a boring food tactic: same breakfast every day, Greek yogurt with berries and about 40g of protein, one giant salad at lunch, dinner on a smaller plate. Sixteen weeks of that and I stopped negotiating with myself at 9pm.

The number I trust at the end is my 34-inch waist and how I do on the stairs, not a slide.

Estimand debates are above my pay grade, but four points wouldn't change my Tuesday either way.

I slept five hours a night for two weeks during a work crunch and my loss flatlined at 19 lbs down despite the same food. Got back to seven and a half and dropped four more in ten days. Sleep might be a bigger lever than which estimand the company picked. Anyone else see that stall when stress spikes?

I've stopped trusting any single morning. Two cups of salty soup on a Wednesday and Thursday's number reads three pounds up, gone by Friday. Weighing daily and only comaring seven-day averages killed the panic for me. The scale is a noisy instrument, not a verdict.

The number that surprised me was my own chart at 10 weeks: 12 lbs down, then only 1.5 a month for the next four. Draw a line through the whole thing and it looks like failure, but the total kept moving.

Trials cut endpoits at fixed weeks, so whoever runs longer tends to show a bigger number, and dose selection stacks on top. That's probably more of the 4.5 points than any estimand fight. Separately, I logged every bite for 90 days and found my 'small' handful of almonds was 400 calories.

Fixing that one habit beat anything I did at the gym, and I still ate the almonds, just eleven of them.
