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.

AJMC

Enlicitide reports address durability and baseline cardiovascular risk

Ahead of the AHA meeting, an original report reviewed enlicitide analyses across PREVENT cardiovascular risk groups and an open-label extension. LDL cholesterol reductions were broadly consistent across risk categories and persisted through Week 104. The extension selected participants who had tolerated and adhered to treatment and lacked a control group, limiting generalization of its long-term findings.

Aurinia reports $232.4 million in nine-month LUPKYNIS net product sales

Aurinia reported LUPKYNIS net product sales of $232.4 million for the nine months ended September 30, 2026, up 18%, including $79.4 million in the third quarter, up 12%. Total company revenue also includes licensing, collaboration, and royalty income. These are commercialization results for an approved oral cyclic peptide, rather than a new indication approval or clinical endpoint readout.

Acta Pharmaceutica Sinica B

New review maps evidence standards for orally active peptides

A new review connects peptide structure, formulation, screening, and pharmacokinetic testing in an evidence-based framework for oral drug discovery. It distinguishes architecture-led libraries, oral optimization of existing hits, and hybrid approaches. The scope includes cyclic and noncyclic peptides; the proposed framework organizes development evidence rather than demonstrating a new therapy or clinical benefit.
