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 figure that counts everyoneCounts everyone: obesity trials report two numbers. We always take the conservative one, which counts every person randomized, including those who stopped the drug. Sponsors name it the “treatment policy” estimand (Novo) or the “treatment regimen” estimand (Lilly and Boehringer); we verify each trial’s analysis plan. We never headline the flattering on-treatment number. prescribed the drug rather than only those who stayed on it, 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.

One bar, a hard zero

← tolerabilityefficacy →
bands0measured
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.

The board

% body weight lost vs placebo · everyone counted · monitored for new evidence
Tolerability bands= AE-discontinuation over placebo · fills leftward = worse
Clean ≤1 pt Mild 1 to 5 Notable 5 to 10 Heavy >10

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. Each division’s frontier is its strongest drug, the top bar, which is what anchors the A tier.  * Retatrutide’s figure is inferred from topline and ADA, not yet peer-reviewed.

On the horizon

These are not graded on the same scale. The evidence is still Phase 2 or topline. The faded, dashed-ring grade shows only where each looks to be aiming, at low confidence. When one earns a Phase 3 readout, it graduates onto the board.
