Protagonist Therapeutics (NASDAQ:PTGX) has announced the submission of a New Drug Application (NDA) to the FDA for icotrokinra, a first-in-class oral peptide therapy for moderate to severe plaque psoriasis. The submission is supported by impressive data from four Phase 3 clinical trials that demonstrated significant efficacy and favorable safety in both adults and pediatric patients aged 12 and older.
The drug, developed in collaboration with Johnson & Johnson, showed superior results compared to deucravacitinib in the ICONIC-ADVANCE studies. Safety data revealed similar adverse event rates between icotrokinra (49.1%) and placebo (51.9%). The treatment offers a unique advantage as a once-daily pill that selectively blocks the IL-23 receptor, potentially transforming the treatment paradigm for plaque psoriasis.
The comprehensive clinical package includes successful results across multiple trials, including ICONIC-LEAD, ICONIC-TOTAL, and ICONIC-ADVANCE 1 & 2, with additional studies ongoing for potential expansion into other indications such as psoriatic arthritis, ulcerative colitis, and Crohn's disease.Protagonist Therapeutics (NASDAQ:PTGX) has announced the nomination of PN-477, a novel GLP-1, GIP, and GCG receptor triple agonist peptide, as a development candidate for obesity treatment. The drug candidate features both oral (PN-477o) and injectable (PN-477sc) formulations, designed for once-daily and once-weekly administration respectively.
The company reports that PN-477 has demonstrated potent in vitro activity in activating all three targeted receptors and has shown robust preclinical proof-of-concept in various animal studies, including diet-induced obesity mouse models, normal dogs, and cynomolgus monkeys. The candidate is engineered to be orally stable with balanced potencies against the three receptors to potentially maximize weight loss benefits while minimizing adverse effects.
Protagonist has initiated IND-enabling studies and expects to begin Phase 1 clinical trials in the second quarter of 2026. The company positions PN-477 as a potential best-in-class treatment option, aiming to offer weight loss comparable to the best injectable treatments while providing the flexibility of both oral and injectable administration routes.
Protagonist Therapeutics (NASDAQ:PTGX) has scheduled a conference call and webcast for Monday, June 30th at 4:30 pm ET to announce its oral obesity development candidate. The presentation will include details about in vitro and pre-clinical proof-of-concept study results.
