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

A QUICK FRAME FOR THE WEEK (FEB 9–13)

This remains a process-first tape:

  • Weekend wall digestion: $KOD ( ▲ 5.38% ) (Saturday data visibility) + $RGNX ( ▼ 0.48% ) (Sunday PDUFA date vs clinical hold) are the only “Monday open” forcing functions.

  • Visibility events > hard binaries this week (MAZE / INAB), but they can still move names via regulatory-alignment tone, trial design specificity, and timeline discipline.

WEEKEND WALL FALLOUT (WHAT MATTERS MONDAY)

REGENXBIO — $RGNX ( ▼ 0.48% ) | RGX-121 (MPS II) | PDUFA: Feb 8 (Sun)

  • Status: Program remains under FDA clinical hold (announced Jan 28) following a CNS tumor in the RGX-111 sister program; FDA cited a potentially shared risk and REGENXBIO noted it had not yet received the full hold letter at the time of the announcement.

  • PoA: 5 (functionally impaired while the hold is active)

  • Desk note: REGENXBIO disclosed preliminary evidence consistent with AAV vector genome integration associated with PLAG1 overexpression—why this trades as platform/class risk, not a single-asset issue.

What to watch today: any formal FDA action/process update mechanics (delay language vs CRL language) and whether the company has now received details from the FDA on the hold.

Kodiak — $KOD ( ▲ 5.38% ) | KSI-101 (MESI) | Angiogenesis 2026: Feb 7 (Sat)

  • Status: Final APEX Phase 1b Week 24 results were scheduled for presentation Saturday (classic weekend disclosure bias).

  • PoA: n/a (data visibility)

What to watch in the read-through:

  • 5mg/10mg safety profile clarity (what changes confidence into PEAK/PINNACLE Phase 3).

  • Durability at Week 24 + any safety/tolerability language that changes the “extended interval” framing.

HARD EVENTS (FEB 9–13)

MAZE Therapeutics — $MAZE ( ▲ 6.22% ) | Feb 11 (Wed), 3:00 PM ET

  • Event: Guggenheim Emerging Outlook: Biotech Summit webcast.

  • Focus (company pipeline framing): watch for execution/timeline updates around MZE829 (APOL1) and MZE782 (SLC6A19).

IN8bio — $INAB ( ▼ 1.51% ) | Feb 12 (Thu), 1:20–1:40 PM ET

  • Event: IO360° Conference presentation (William Ho).

  • Topic: “DeltEx DRI approach… results from Phase 1/2 study in newly diagnosed GBM” (agenda language).
    Listen for: trial design specificity, durability, and any “FDA alignment” cues in the forward path.
