Next 3 weeks on the FDA calendar and it is not crowded. that is kind of the point Oct 26 $IONS bepirovirsen for chronic hepatitis B, B Well trials already showed functional cure after treatment stopped Oct 30 $INO INO 3107 for recurrent respiratory papillomatosis, accelerated approval path and inspections already done Nov 1 $AGIO mitapivat for sickle cell disease, a Sunday date so Friday is the practical window quiet on both sides of that little cluster imo. nobody is loud about any of these yet and yes, every one of these dates traces back to a company release or an SEC filing, not calendar gossip

$IONS Bounced off oversold and rounding out the bottom. Could get better as we assess the right side.

$IONS Ionis got two good pieces of news in about a day and the stock still closed down Friday. UBS upgraded it to Buy on Thursday and raised its target to 88 from 46. Then the CHMP recommended expanding TRYNGOLZA in the EU for severe hypertriglyceridemia (triglycerides at or above 880 mg/dL), ahead of the timeline Ionis had expected. Final European Commission decision is expected in Q4. The trial data behind it: placebo-adjusted triglyceride cuts of up to 72% at six months in CORE and CORE2, and an 85% reduction in acute pancreatitis events over 12 months pooled. One nuance on the EU piece: Sobi holds the commercialization rights outside the US, Canada and China, so for Ionis this is partner economics, not direct EU sales. Stock closed Friday at 42.94, down 2.7%, down about 46% year to date and pretty close to the 52-week low of 42.08.

Latest company news, October 16, 2026: Ionis and partner Sobi said the EMA's CHMP recommended extending the EU indication of TRYNGOLZA (olezarsen) to adults with severe hypertriglyceridemia (fasting TG of 880 mg/dL or higher), based on Phase 3 CORE and CORE2.

$IONS Ionis Pharmaceuticals, an RNA-drug maker: the EU CHMP nod for TRYNGOLZA in severe hypertriglyceridemia covers only adults with triglycerides ≥880 mg/dL, about 700,000 of ~2 million EU5 patients, narrower than its US label at ≥500. Partner Sobi sells it in the EU; Ionis gets milestones and tiered royalties up to the mid-20% range on net sales. No amounts or EU sales forecasts are given to size vs a ~$7.33B market value ($44.12, 16:00 ET Oct 15, 2026). Upside: the opinion came ahead of schedule. European Commission decision expected in Q4 2026.

Preclinical evidence shows what a therapy may be capable of. Clinical evaluation begins to show how it performs in patients. Across biotech, that transition is critical—from RNA-targeted medicines at $IONS to gene-editing approaches at $CRSP. For $PPCB, February 2027 is targeted to mark that next step, with PRP’s Phase 1b First-In-Human study evaluating safety, tolerability, PK, PD and preliminary antitumor activity in up to 50 patients. Moving into the clinic begins a new stage for PRP, where clinical data can further define the program and shape the path ahead. Each milestone brings PRP one step closer to clinical evaluation.

$IONS still has the $42.82 gap to fill from August 2025 on the weekly. I expect it will keep going lower with every good news story or PR that comes out. Cathie Wood Curse?
