What changed

Researchers developed HighPlay3 to balance cyclic peptide target binding and membrane permeability through iterative structural assessment and prediction. Experimental screening produced micromolar binders against MDM2 and GABARAP. Among tested active GABARAP candidates, GAB-D4 showed the highest Caco-2 apparent permeability with no apparent net efflux. These are early laboratory results, not demonstrated human oral bioavailability.

Why it may matter

Integrating permeability early could reduce later optimization cycles, but oral exposure, selectivity, and safety still require substantial experimental validation.

The interpretation above is analysis, not a conclusion attributed to the original source.

Icotrokinra meets Phase 3 joint-response endpoint in biologic-naive psoriatic arthritis

Johnson & Johnson reported that 58% of patients receiving icotrokinra 200 mg achieved ACR20 at Week 16 in ICONIC-PsA 1, versus 41% with placebo. The oral IL-23 receptor peptide also showed skin responses. The company reported no new safety signals through Week 24; active psoriatic arthritis remains an investigational indication.

Entera reported $265.9 million in cash and cash equivalents at September 30, plus $6.5 million in restricted cash. Its November 6 update targets first site activation for an approximately 900-patient EB613 osteoporosis Phase 3 trial in late 2026. EB613 is an oral PTH(1-34) program, included here as an adjacent oral-peptide delivery development, not a cyclic-peptide candidate.

Johnson & Johnson reported that ICONIC-ASCEND met its Week 16 co-primary endpoints: PASI 90 responses were 55.2% with icotrokinra versus 3.6% with placebo, and IGA 0/1 responses were 70.4% versus 9.5%. At Week 28, the oral peptide met noninferiority criteria versus ustekinumab across multiplicity-controlled key secondary skin-clearance endpoints.
