What changed

Unnatural Products closed a $45 million Series B led by The Venture Collective, with argenx, Droia, and existing investors participating. Funding supports its computational design, automated chemistry, high-throughput screening platform, and macrocyclic peptide pipeline. The oral-delivery strategy remains a development objective; this financing announcement does not establish human oral efficacy for a newly disclosed candidate.

Why it may matter

Funds translation from platform discovery toward candidates; named assets, administration routes, and human exposure data remain important next milestones.

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

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.

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.
