Understanding Patient Preferences in Psoriasis, With Andrew Blauvelt, MD, MBA

As a wave of new oral therapies approaches regulatory review for moderate-to-severe plaque 

 (PsO), a better understanding is needed of what factors may affect patient preference toward different modalities of treatment.

caught up with Andrew Blauvelt, MD, MBA, dermatologist, Blauvelt Consulting, at the 

2026 American Academy of Dermatology (AAD) Annual Meeting

 held in Denver, Colorado, from March 27-31, to learn more about how the field is coming to better understand and support patient preferences.

In this conversation, Blauvelt pushed back on what he described as a reflexive tendency to assume that the availability of once-daily oral options will automatically translate into patient demand. The reality, he noted, is considerably more nuanced. Across several published preference studies he reviewed, the direction of patient preference varied substantially depending on disease, severity, injection characteristics, and country of origin.

In 1 study comparing patients with atopic dermatitis and psoriasis on the question of route-of-administration preference, the 2 groups diverged: atopic dermatitis patients favored oral therapy, while psoriasis patients expressed a preference for injectable treatment.

 A second psoriasis-specific study found that disease severity modulated preference within the same patient population — those with more moderate disease leaned toward pills, while patients with more severe disease preferred injections.

The implication, Blauvelt noted, is that 2 studies conducted in the same disease reached different directional conclusions depending on how the question was asked and which patients were enrolled.

Geographic context introduced additional variation. A study conducted in Japan found a clear preference for oral therapy, while a comparable study conducted in Germany yielded the opposite result, with German patients favoring injections.

 And a further study found that what mattered most was not simply whether a treatment was injectable, but what kind of injection it was: patients preferred shots when they were infrequent — monthly or less — and not painful, but shifted toward pills when injections were more frequent or associated with discomfort.

Blauvelt framed these findings as relevant context for interpreting the clinical landscape now emerging around envudeucitinib, zasocitinib, and icotrokinra, each of which offers once-daily or twice-daily oral dosing and carries efficacy data approaching or overlapping with injectable biologics in some measures. The case for oral therapy is real, he argued, but it is not universal — and the patients most likely to benefit from the shift to pills may be those with moderate disease, those averse to injections for logistical or geographic reasons, and those in clinical settings where biologic prescribing remains limited. For patients with more severe disease who are already on well-tolerated, infrequent injectable biologics, the calculus may be less straightforward than the narrative around the oral pipeline sometimes suggests.

How Envudeucitinib May Fit Into the Evolving Oral Psoriasis Landscape, With Andrew Blauvelt, MD, MBA

 held in Denver, Colorado, from March 27-31, marked a watershed moment for the oral psoriasis treatment landscape, with late-breaking phase 3 data presented for 2 next-generation TYK2 inhibitors — envudeucitinib and zasocitinib — arriving just weeks after the FDA approval of icotrokinra (Icotyde), the first oral IL-23 receptor antagonist approved for moderate to severe plaque psoriasis. Andrew Blauvelt, MD, MBA, owner of Blauvelt Consulting, in Annapolis, Maryland, and a principal investigator on the ONWARD program, spoke about where envudeucitinib fits in the context of this rapidly expanding field. 

Blauvelt characterized envudeucitinib as a second-generation TYK2 inhibitor specifically engineered for complete 24-hour target coverage — distinct from the first approved agent in the class, deucravacitinib — and the only TYK2 inhibitor to date shown to achieve maximal inhibition over a full dosing interval in humans. The ONWARD1 and ONWARD2 trials together enrolled more than 1,700 adults with moderate to severe plaque psoriasis, randomized 2:1:1 to envudeucitinib 40 mg twice daily, placebo, or the active comparator apremilast, with co-primary endpoints of PASI 75 and static Physician's Global Assessment (sPGA) 0/1 at week 16. Both studies met all primary and secondary endpoints with high statistical significance versus placebo (

 <.0001). At week 16, approximately 74% to 75% of envudeucitinib-treated patients achieved PASI 75 and 59% achieved sPGA 0/1. Response continued to deepen through week 24, at which point approximately 80% achieved PASI 75, approximately 65% achieved PASI 90, and more than 40% achieved PASI 100 — complete skin clearance. Envudeucitinib outperformed apremilast on all PASI endpoints at week 24 (

 <.0001), with separation from placebo on PASI 90 observed as early as week 4. The safety profile was favorable and consistent with phase 2 findings, with nasopharyngitis and upper respiratory tract infection the most common adverse events and notably no lipid signal of the type observed in earlier deucravacitinib studies.

Zasocitinib, Takeda's once-daily investigational TYK2 inhibitor, presented concurrent phase 3 data from the LATITUDE PsO 3001 and 3002 trials at the same meeting. In those studies, 71.4% and 69.2% of zasocitinib-treated patients achieved sPGA 0/1 at week 16 versus 10.7% and 12.6% with placebo (

 <.001), with PASI 75 responses observed as early as week 4 and more than 90% of week 40 responders maintaining response through week 60. Also arriving just before AAD, icotrokinra received FDA approval on March 18, 2026 as the first targeted oral peptide to precisely block the IL-23 receptor, with approval based on the phase 3 ICONIC program in approximately 2,500 patients. In the ICONIC-ADVANCE head-to-head studies, approximately 70% of patients achieved IGA 0/1 and 55% achieved PASI 90 at week 16, with icotrokinra demonstrating superiority over deucravacitinib at weeks 16 and 24.

Blauvelt placed these 3 agents in direct relation to one another, noting that the best IL-23 and IL-17 biologics likely still represent the ceiling for skin clearance. For patients prioritizing maximum efficacy, he would continue to favor those agents; however, for the many patients who prefer oral therapy and the many clinicians who remain reluctant to prescribe biologics, he characterized icotrokinra, envudeucitinib, and zasocitinib as agents that will move immediately to the top of the oral treatment hierarchy. He noted that dosing may be an early point of practical differentiation — zasocitinib and icotrokinra are once daily, while envudeucitinib is currently dosed twice daily, though Alumis has indicated plans to develop an extended-release once-daily formulation. He also raised the possibility that performance in psoriatic arthritis could ultimately drive prescribing choices among these agents if data reveal meaningful differences in joint outcomes. An NDA submission for envudeucitinib is planned for the second half of 2026.

Phase 3 ONWARD data for the investigational TYK2 inhibitor envudeucitinib join a rapidly crowding oral psoriasis space.


ONWARD: Oral Envudeucitinib Demonstrates High PASI Responses in Phase 3, With Andrew Blauvelt, MD

Phase 3 data for envudeucitinib — a next-generation, highly selective oral TYK2 inhibitor precision-engineered for maximal 24-hour target inhibition — have demonstrated robust skin clearance in moderate-to-severe plaque psoriasis (PsO), in new data presented at the 

 held in Denver, Colorado, from March 27-31.

To discuss the findings, we spoke with Andrew Blauvelt, MD, MBA, Owner of Blauvelt Consulting, LLC, in Annapolis, Maryland, and a principal investigator on the ONWARD program, following his late-breaking oral presentation at the meeting. The ONWARD1 and ONWARD2 trials together enrolled more than 1,700 adults with moderate-to-severe plaque psoriasis, randomized 2:1:1 to envudeucitinib 40 mg twice daily, placebo, or the active comparator apremilast, with co-primary endpoints of PASI 75 and static Physician's Global Assessment (sPGA) 0/1 at week 16. Both studies met all primary and secondary endpoints with high statistical significance versus placebo (

At week 16, approximately 74–75% of envudeucitinib-treated patients achieved PASI 75 and 59% achieved sPGA 0/1 — substantially higher than both placebo and apremilast. Blauvelt highlighted the week 24 data as particularly noteworthy: consistent with the class behavior of TYK2 inhibitors, response deepened over time, with approximately 80% achieving PASI 75, approximately 65% achieving PASI 90, and more than 40% achieving PASI 100 — complete clearance — by week 24. Envudeucitinib outperformed apremilast on all PASI endpoints at week 24 (

 <.0001), and separation from placebo on PASI 90 was observed as early as week 4. Patient-reported quality-of-life and itch measures were consistent and clinically meaningful throughout. 

On safety, the profile was favorable and consistent with phase 2 findings — the most common adverse events were nasopharyngitis and upper respiratory tract infection, with no major cardiovascular events, no tuberculosis reactivation, no clinically relevant hematologic or metabolic laboratory abnormalities, and notably no lipid signal of the kind observed in earlier deucravacitinib studies. 

Blauvelt distinguished envudeucitinib from deucravacitinib as a second-generation TYK2 inhibitor specifically engineered for complete 24-hour target coverage — the only TYK2 inhibitor shown to achieve maximal inhibition over a full dosing interval in humans. An NDA submission is planned for the second half of 2026, with a once-daily extended-release formulation and a pediatric program both in development.

“[This was] a major reveal… phase 3 results for a new oral drug for psoriasis called envudeucitinib, next gen TYK2 inhibitor. If all goes well, if the FDA likes it… usually when phase 3 results are presented at AAD, oftentimes, we will see approval of the drug in the coming year,” Blauvelt said.
