Upfront Briefing

Blackstone handed Apogee up to $1.3B and didn't ask for a single share in return — non-dilutive is the new flex. Sanofi's venglustat grabbed US priority review in type 3 Gaucher, and GSK finally showed its homework on bepirovirsen in hepatitis B (spoiler: an actual functional cure).

Net-net: late-stage money is cheap if your data's good, the FDA clocks are speeding up, and timelines are still the only thing that move models.

Tape Action

Instrument Last close 1D % YTD %
S&P 500 7,520.4 0.0% 9.7%
Nasdaq 100 29,973.6 (0.1%) 18.9%
Russell 2000 2,919.9 0.0% 16.4%
Healthcare (XLV) 148.8 0.2% (4.3%)
Biotech (XBI) 134.4 0.8% 10.6%
Nasdaq Biotech (NBI) 5,931.3 0.3% 3.9%
Clinical Trials (BBC) 43.6 0.4% 15.8%
  • Records on autopilot — just don't look under the hood: the Dow tagged a fresh high (+0.4%) mostly because crude took a ~5.5% dive on Strait of Hormuz headlines, the S&P (+0.02%) limped to its own record, and the Nasdaq got mugged by a chip pullback as Micron gave back part of its moonshot.
  • Biotech didn't wait for the macro — XBI (+0.8%) was the green standout, riding its own catalyst tape: Apogee's $1.3B Blackstone bag, GSK/Ionis' hep B cure data, and Sanofi's GD3 priority review.
  • Market data: U.S. cash close Wednesday, 27 May 2026.

The Big 3

1
Blackstone backs Apogee AD therapy ahead of Phase 3
  • Apogee dropped fresh Apex Part B Phase 2 data for zumilokibart (anti-IL-13 mAb) — 65.9% of mid-dose patients hit EASI-75 at 16 weeks — and walked away with up to $1.3B from Blackstone to bankroll Phase 3 and launch. Shares popped ~16%. Not a bad Wednesday.
  • Why it matters: The capital is non-dilutive — up to $800M synthetic royalty plus up to $500M senior debt, staged ($100M at signing, $100M at Phase 3 enrolment, $200M on positive data), with low-to-mid single-digit royalties over 15 years that lapse above $8B in sales. It funds three Phase 3 trials (2H26 start) without tapping equity and sets up zumilokibart's less-frequent dosing against Dupixent and Ebglyss in a multibillion-dollar AD market.

Sanofi’s venglustat gets US priority review in Gaucher 3
  • Sanofi’s venglustat was accepted for priority review in the US to treat type 3 Gaucher disease. The designation shortens the regulatory path for the rare-disease asset.
  • Why it matters: Priority review sets a 25 November 2026 PDUFA date for venglustat, an oral, brain-penetrant glucosylceramide synthase inhibitor. Backed by Phase 3 LEAP2MONO (oral venglustat vs IV enzyme replacement), it could become the first US therapy for the neurological manifestations of GD3 — a defined rare-disease catalyst and an extension of Sanofi's lysosomal-storage franchise.

GSK details positive Phase 3 HBV data for Ionis-licensed drug
  • GSK and partner Ionis reported detailed pivotal data for bepirovirsen, a finite six-month antisense (ASO) therapy for chronic hepatitis B — published in NEJM and presented at EASL. Pooled B-Well 1/2 showed a 19% functional cure rate (233/1,220) vs 0% on standard of care (p<0.001), rising to 26% in patients with lower viral load.
  • Why it matters: Functional cure is the prize in CHB, where current nucleos(t)ide analogues deliver ~1% annual cure and lifelong therapy. A first-in-class finite option with a 26 October 2026 PDUFA (priority review + Breakthrough Therapy) hands GSK a near-term launch catalyst and validates Ionis's partnered-antisense platform and royalty stream.
