The obesity-drug scoreboard

How good is it, really, and how sure are we?

One standardized verdict per drug, graded against its own division, so a best-in-class pill is not punished for not being an injection. Every efficacy number is placebo-adjustedPlacebo-adjusted: the drug’s result minus the placebo group’s. Every trial runs a diet-and-lifestyle program in both arms, so the placebo group already loses a few percent. The drug’s real effect is the gap above it., uses the discontinuation-inclusive estimateTreatment policy or treatment regimen: the average effect of assignment regardless of whether participants later stop treatment or have other changes specified in the trial’s analysis plan. Follow-up outcomes after discontinuation are used when available, and missing outcomes are estimated. The alternative trial-product or efficacy estimand asks what would have happened under hypothetical continued treatment; it is not a completers-only population., and is time-standardized. The grade only counts what the evidence can back: a big press-release number never outranks a confirmed one.

Reductive on purpose. Rigorous underneath.

The grade: a tier, within division

A Class-leading for its route
B Competitive
C Lagging the frontier
A tier, not a rank: two drugs can share “class-leading” while the numbers show one a hair ahead.

Confidence: how sure we are

Approved Regulator-cleared, on the market.
Certified A Phase 3 result, topline or published.
Projected Only Phase 2; a grade we project, not crown.
NR Too early to rate at all.
The badge ring says it too: solid for the board (Approved, Certified), dashed for the watchlist (Projected, NR). The two never mix into the ranking.

Efficacy is a measured bar right of zero; tolerability is coarse bands that run cool→hot left of it. Good: long blue, few amber.

This strip is the quick key. The methodology page defines every threshold and is linked from every drug and comparison page.

Against the hype: oral semaglutide out-does orforglipron on both efficacy and tolerability. Orforglipron’s real case is convenience: no fasting, room temperature, scalable. See the head-to-head.

The bigger question behind this division: is the pill as good as the shot? A full breakdown puts every drug on one magnitude scale, then splits it into weight loss, tolerability, and the trade-off.

Efficacy bars show % of body weight lost vs placebo, so longer is better. Bars share one absolute 0 to 25% scale across both divisions, so an oral and an injectable at the same length really did lose the same amount, the fact behind is the pill as good as the shot? Each division’s frontier is its strongest drug, the top bar, which is what anchors the A tier. Each drug is scored once, at the highest standard maintenance dose reached through the usual labeled escalation. A higher dose with an additional tolerance and clinical-indication gate may be shown beneath its drug, but it is not separately ranked and does not set the frontier.  * Retatrutide’s figure is inferred from topline and ADA, not yet peer-reviewed.

On the horizon

projected only · kept off the ranked board

These are not graded on the same scale. The phase shown is how far the program has got; none of these has posted a Phase 3 result yet, which is why several sit in Phase 3 and are still not rated. The faded, dashed-ring grade shows only where each looks to be aiming, at low confidence, and against its own route. A Phase 3 result, topline or published, is what graduates one onto the board.

RetiredPemvidutide (Altimmune), injectable: Obesity development shelved in 2025. Altimmune refocused pemvidutide on liver disease, and guides no obesity milestone. Off the board and off the watchlist, kept for the record.
