​If upcoming trial data holds, the IBD space is primed for major shifts over the next decade. $PTGX and $JNJ could dominate first-line treatment as oral IL-23s replace injectables. $SYRE stands out as a prime buyout candidate through combo therapies and strong Phase 2 data (40% remission rate), while $AGMB targets high-unmet needs in fibrostenosing Crohn's.

Here is how the IBD landscape could evolve over the next decade, assuming strong upcoming trial data for all players listed: -$PTGX’s and $JNJ’s Icotrokinra becoming the frontline standard of care for IBD. IL-23 pathway inhibitors already have displaced TNFi’s due to unprecedented safety and an oral IL-23 will capture a large market share from injectables as we have already seen in PsO. -$SYRE ’s combo therapies step in for a significant percentage of monotherapy non-responders. The TL1A/IL-23 combo is in phase 2 already and Spyre also has a half-life extended alpha 4 beta 7 antibody with a 40% (!) clinical remission rate on its own that also has combo potential. All three targets have an excellent safety profile. Spyre is a prime buyout candidate, especially given strong phase 2 SKYLINE results in 2026 and 2027. -$AGMB’s ALK5i used in fibrostenosing Crohn’s Disease, a highly unmet medical need. Patients will remain on immune pathway inhibitors like the ones above.

$PTGX Just a reminder that Protagonist is 98-99% institutionally owned, which means if you’re a retail shareholder you’re an investor with exquisite taste. I posted about this company in March and you can see what retail has missed out on just since then.

$TAK Took a position here due to the clear sector rotation from AI into pharma plus upcoming catalysts including Rusfertide but also the orexin receptor antagonist for narcolepsy and the oral TYK2 for psoriasis and psoriatic arthritis. Note that TAK-279 (zasocitinib) directly competes with Icotyde as an oral psoriasis treatment so this could affect $PTGX ’s stock price. However, positive Ico data for IBD would likely mitigate and outweigh this effect, so I am still bullish on both companies

$PTGX Did a deeper dive on this and now appreciate two peices of information that now make me weight the scales towards strongly bullish on this company. First, I underestimated how strong the patient preference is for a daily oral pill compared to even an infrequent subq injectable. Second, their peptide technology actually stabilizes the molecule to survive stomach acid and be absorbed without needing an enhancer. This distinction obviates the need for complex carrier systems and gives them a competitive advantage in the space. The more I read about this the more they seem to be an obvious buyout target once the Rusfertide news comes out (if it’s positive), but even if not I would guess they’ll have robust growth over the next few years.

$PTGX Rusfertide news expected next month. If approved, and the phase 3 data and priority review all suggest it will be, Protagonist gets an immediate $200 mil from Takeda. After that investors can look forward to Ico’s indication expansion readouts as early as Q4 this year. However, the price of this stock is already at a premium, and if news is bad for any of their trials we could see a big drop. We could also see a sell-the-news hit as well. Should be interesting to see how this looks in a year. Cautiously optimistic.

Truist⬆️ $PTGX's PT to $145 and said ~~ We reiterate our Buy rating of PTGX as we continue to be bullish on broader Icotyde commercial opportunity. $JNJ TAK $ABBV ALMS BMY ABVX Truist added—Johnson & Johnson (JNJ, NR) commentary on Icotyde continues to indicate 1) rapid access and uptake for the drug in Psoriasis; 2) strong KOL enthusiasm driven by label strength, & 3) comments around Ico potential to be "one of their biggest products ever", raising overall peak sales estimates beyond $10B. We have updated our model to reflect slightly increased market share of Icotyde in PsO; new PT is $145/sh vs. $121 prev.

BMO Capital reiterated $PTGX Outperform; $112, and said: Main Character Energy—Momentum Increases Upside Potential for PTGX. $JNJ $TAK ABBV BMY ALMS ABVX BMO Capital added—Commercial launches and anticipated approvals could enable accelerated clinical diversification and growth for Protagonist. As of March 31, 2026, the company held cash and cash equivalents of $620M, with an anticipated runway through ~2028. Following the recent Icotyde approval (here) and launch, we could see potential additional indication approvals for the product into the decade, and a nearer-term rusfertide approval later this year (Aug. 2026 PDUFA). We continue to like collaboration revenue opportunities supportive of clinical development/diversification and look for clinical derisking of earlier-stage assets for growth beyond Icotyde/rusfertide.
