iStock, designer491 AbbVie’s Skyrizi appears to have stronger efficacy than Johnson & Johnson’s newly approved pill Icotyde, as well as a less frequent dosing schedule that patients could prefer, according to analysts at BMO Capital Markets. AbbVie is ready to face off against the newest kid on the immunology block: Johnson & Johnson and Protagonist Therapeutics’ peptide pill Icotyde. The FDA gave the greenlight to Icotyde earlier this month, marking the first oral targeted therapy that blocks the IL-23 receptor and completely clears the skin of patients with plaque psoriasis. This puts the drug’s sponsors in direct competition with immuno stalwart AbbVie, which owns Skyrizi, a biologic therapy that also targets the IL-23 cascade. First approved in April 2019 for moderate to severe plaque psoriasis, Skyrizi has since become a cornerstone of AbbVie’s portfolio, growing into a $17.562 billion franchise in 2025 to help the pharma gracefully ride out the patent cliff of its mega-blockbuster Humira. The therapeutic antibody has also picked up several other indications, including Crohn’s disease and ulcerative colitis. Skyrizi was the industry’s fifth top-selling drug last year.

March 4, 2026 · 9 min read · Tristan Manalac Read more “While Icotyde is expected to take share, Skyrizi is likely to remain a value driver for AbbVie across I&I,” analysts at BMO Capital Markets wrote in a note to investors on Friday afternoon after catching up with AbbVie management to clear up competitive concerns following Icotyde’s approval. “AbbVie does not underestimate competitive threats,” the note continued, “but is confident in the strength of Skyrizi.” Key to AbbVie’s confidence is the drug’s superior efficacy. At 16 weeks in the Phase 3 UltIMMa-1 and UltIMMa-2 studies, 70% to 73% of patients treated with Skyrizi saw a 90% improvement from baseline in Psoriasis Area and Severity Index (PASI) scores, a key tool used to assess disease severity, as compared with placebo. At the same follow-up, 36% to 49% saw a 100% PASI improvement, BMO added, meaning the complete resolution of lesions. In contrast, Icotyde achieved a 46% placebo-adjusted PASI-90 at 16 weeks in the late-stage ICONIC-LEAD trial, while roughly 27% achieved PASI-100, BMO reported. (In the absence of a direct head-to-head study, cross-trial comparisons are inconclusive.) Aside from an efficacy edge, Icotyde’s oral availability and daily dosing schedule could also work against it, the analysts continued. “Frequently dosed orals often bring adherence challenges with risk of reduced real-world efficacy,” they explained, noting that skipped doses could lower the drug’s therapeutic benefit. In turn, “providers and patients may favor longer-acting/durable therapies like Skyrizi,” which is administered subcutaneously every three months. Approvals J&J Wins FDA Nod for First Targeted Oral Anti-IL-23 Therapy for Plaque Psoriasis Icotyde, co-developed by Johnson & Johnson and Protagonist Therapeutics, is backed by data from the Phase 3 ICONIC program, which, among other advantages, showed significant superiority over Bristol Myers Squibb’s Sotyktu. March 18, 2026 · 2 min read · Tristan Manalac Read more Despite these key advantages for Skyrizi, “we remain positive on the commercial opportunity presented by Icotyde as the first and only oral IL-23 on the market,” BMO stated in its Friday note. J&J and Protagonist are also proposing Icotyde for psoriasis more broadly, an “already large” market that could unlock billions in opportunity for the drug. Peak psoriasis sales for the pill could hit $3.2 billion in 2040, the firm forecasted. Another plaque psoriasis player is Takeda, though the pharma is far behind AbbVie and J&J, with its TYK2 inhibitor zasocitinib still in Phase 3 development. Data from a pair of late-stage studies, presented Saturday at the American Academy of Dermatology Annual Meeting, showed that daily doses of zasocitinib induced clear or almost clear skin in 69.2% to 71.4% of patients, as compared with 10.7% to 12.6% of placebo comparators and 29.7% to 32.1% of those on Amgen’s Otezla. PASI-90 was likewise significantly higher in the zasocitinib arms versus placebo and Otezla. Takeda plans to zasocitinib’s approval during its fiscal year 2026, which starts on April 1.

iStock, Yutthana Gaetgeaw Takeda’s layoffs include cutting 247 people in Massachusetts. The workforce reduction is meant to help offset investments in areas including a product launch for oral drug candidate zasocitinib, for which the pharma today announced positive Phase 3 data. The workforce impact of Takeda’s recently announced reorganization has become clearer. The Japan-based pharma estimates the restructuring will affect around 634 U.S. employees, according to a Worker Adjustment and Retraining Notification (WARN) Act notice . Takeda began notifying employees on March 25, the same day it announced a business transformation , which includes streamlining corporate functions. However, the company noted in the WARN notice that the total number affected could change as staff pursue and accept redeployment opportunities across its global network. Takeda’s cuts include 247 employees in Cambridge, Massachusetts, effective July 1, 2026, through Dec. 31, 2027. To understand where other layoffs will take place, BioSpace has requested a copy of a document mentioned in the WARN notice that lists the number of individuals affected by state. In last week’s announcement, Takeda noted that the restructuring, which includes “strategically prioritizing resources,” is expected to save more than 200 billion yen—about $1.25 billion—by fiscal year 2028. The company explained that the savings will offset investments needed to prepare for multiple launches, including oveporexton, usfertide and zasocitinib; progress the late-stage pipeline; and support strategic technology investments. Takeda announced today promising data for zasocitinib, an oral tyrosine kinase 2 (TYK2) inhibitor, in adults with moderate to severe plaque psoriasis . In the Phase 3 Latitude PsO 3001 and 3002 studies, more than half of patients treated with the drug candidate achieved clear or almost clear skin at week 16, a key measure of treatment success, according to the pharma. Zasocitinib also demonstrated statistically significant improvements in complete skin clearance. Takeda expects to submit a new drug application for zasocitinib in fiscal year 2026. The pharma acquired zasocitinib from Nimbus Therapeutics for $4 billion at the end of 2022 to challenge Bristol Myers Squibb’s kinase inhibitor Sotyktu. Takeda in December 2025 reported positive results from the Phase 3 LATITUDE studies, noting that when compared with placebo and Amgen’s Otezla, about 30% of treated patients achieved completely clear skin, or a score of 100 on the Psoriasis Area and Severity Index (PASI). The company’s latest layoffs join a series of cuts from the past two years. Takeda let go of nearly 1,500 employees in the U.S. and Austria in 2024 and early 2025 and 137 in October 2025. In January, news broke that 243 people would be laid off across its U.S. operations.
