Technology, programs & evidence

AUBE00 is an oral pan-KRAS macrocyclic peptide from the SnipeTide platform; Phase 1 began in 2025.

LUNA18 was discontinued in 2025. The annual report states that human oral absorption was confirmed and development shifted to AUBE00. This is company-reported information, not publicly available quantitative clinical data.

As of 2026-09-30, the website also listed AQUA07, an oral macrocyclic allosteric ALK inhibitor. Its clinical stage was not confirmed in this review.

The July 24 company release confirms clinical entry; the Japanese registry identifies an oral Phase 1 study recruiting participants.

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.
