PoA = probability-of-approval band (directional only; not FDA guidance).

THE FRAME (FEB 27–MAR 2): “CLOCKS COLLAPSE → EXECUTION TAPE + CONFERENCE NOISE”

Last Friday’s “weekend clock risk” is gone — the market got three early-week FDA prints and now shifts to launch posture + conference framing:

So the tape splits:

  • Tape A (now): ASCO GU + AAAAI data cadence (headline risk is dataset shape, not binary approvals).

  • Tape B (next week): the next clean regulatory clock ($LNTH ( ▲ 1.22% ) Mar 6) plus March label/CMC events.

THIS WEEK’S BIG REGULATORY PRINTS (DONE)

VNDA — $VNDA ( ▲ 2.56% ) | BYSANTI (milsaperidone) | FDA APPROVAL (Feb 20)

What matters now: label breadth + payer friction + “next indication” optionality (adjunct MDD remains the longer-dated narrative).

REGN/SNY — $REGN ( ▲ 1.34% ) | Dupixent (AFRS) | FDA APPROVAL (Feb 24)

What matters now: uptake pace in a surgery-linked, high-burden niche; how quickly ENT/allergy practice patterns absorb it.
(Keep claims tight: “approved for AFRS” is enough — avoid “only therapy” language.)

ETON — $ETON ( ▼ 0.81% ) | Desmoda (desmopressin oral solution) | FDA APPROVAL (Feb 25)

Trade lens: clean “approval → launch execution” tape; early scripts + coverage decisions matter more than science now.

AFTERSHOCKS (POST-APPROVAL TAPE)

  • $ETON ( ▼ 0.81% ) : launch target Mar 9 → watch early access/coverage and initial traction.

  • $VNDA ( ▲ 2.56% ) : NCE glow fades fast → the market pivots to commercial reality and psych channel dynamics.

  • $REGN ( ▲ 1.34% ) : adoption curve will be driven by prescriber behavior + pathway placement, not a debate over biology.

IMMEDIATE VISIBILITY / TRADEABLE WINDOWS (NEXT ~7 DAYS)

ASND — $ASND ( ▼ 0.67% ) | TransCon CNP (achondroplasia) | PDUFA: Sat Feb 28

Only remaining “real” FDA clock in this window.
Watch: label language vs Voxzogo, any post-approval commitments, and manufacturing/CMC tone.

TARA — $TARA ( ▲ 6.07% ) | TARA-002 (NMIBC) | ASCO GU poster: Fri Feb 27

This is the event. Updated interim dataset for BCG-unresponsive cohort hits Friday.
Watch the tape-movers:

  • CR with maturity (6-mo vs 12-mo durability)

  • any-time CR vs durable CR (front-loaded responses get punished)

  • safety/discontinuations + “registrational cohort” messaging (clear path vs hand-waving)

CLDX — $CLDX ( ▼ 2.29% ) | barzolvolimab (CSU/ColdU/SD) | AAAAI: Feb 27–Mar 2

Multiple Phase 2 datasets at AAAAI; allergy/immunology room narrative can move this quickly.
Watch: durability + re-treatment behavior and whether “disease modification” framing holds up.

WHAT WE MISSED / WHAT CHANGED SINCE LAST FRIDAY

  • $REGN ( ▲ 1.34% ) Dupixent AFRS was a Feb 28 PDUFA, but approved early (Feb 24) → treat as “DONE,” not upcoming.

  • $VNDA ( ▲ 2.56% ) BYSANTI approved Feb 20 → “weekend gap risk” no longer relevant.

  • $ETON ( ▼ 0.81% ) Desmoda approved Feb 25 → forward-looking hook is launch execution (Mar 9 target).

Pipeline radar (new Priority Review acceptances):

  • $RARE ( ▲ 1.0% ) (Ultragenyx) DTX401 — BLA accepted w/ Priority Review; PDUFA Aug 23, 2026.

  • $IONS ( ▲ 1.47% ) olezarsen (sHTG) — sNDA accepted w/ Priority Review; PDUFA Jun 30, 2026.

CLOSING NOTE

Treat this as two tapes:

  • Tape A (now → Mar 2): conference-driven price discovery ($TARA/$CLDX) + one remaining FDA clock ($ASND).

  • Tape B (Mar): cleaner calendar trades where positioning is about label/CMC language + execution, not storytime.
