Brand rules in.
Consistent outputs out.

Four brands. Four industries. One methodology made visible. For each case below you can see the brand brain that was loaded — claims library, voice rules, forbidden phrases, MLR-derived tonal preferences, audience segments — and the variants the engine produced against those rules. Where the rail caught a borderline framing, you can see the original alongside the auto-rewrite. Compliance flags are real. Rule-respect annotations are real. The methodology is the same across every case.

How OVYN™ produces these — the methodology
01
Brief intake
Structured. Brand · audience · channel · asset · claim · constraint. Six fields, one schema.
02
Brand-trained generation
Per-tenant fine-tune on the brand's claims library, voice rules, and approved-content history.
03
Pre-check rail
Eight rule families. Deterministic + LLM-judged. Both must agree to pass.
04
Channel adaptation
One approval, every surface. Email, paid social, LinkedIn, organic — same content, native render.

VANTAGE showed a median PFS extension in sorafenib-experienced patients [L-C01].
In VANTAGE (NEJM 2025), median PFS was 5.8 months for vanaclostat vs 3.9 months for placebo (HR 0.68; p=0.0021) [L-C02]. Overall survival data are immature. Treatment decisions in advanced HCC remain individualized; fair-balance with adverse-event profile is required for full risk/benefit communication.

Hospital P&T committeesFormulary Summary — VANATAR Mechanism & Safety Trade-Offs in Advanced HCC
VANATAR is a multi-kinase inhibitor with activity against VEGFR2, FGFR1, and RET (L-C03), contributing to its observed PFS benefit in VANTAGE (median 5.8 vs 3.9 months, HR 0.68; L-C02), though the clinical significance of PFS as a surrogate endpoint warrants consideration. The safety profile in Child-Pugh A patients was manageable (L-C04), yet hand-foot syndrome, hypertension, and diarrhea were common (L-C06) and required dose modifications from the standard 400mg daily (L-C05). Formulary decision-making should weigh the modest PFS gain against AE management resources and the lack of head-to-head data with other second-line TKIs.

community oncologySafety Profile Overview: VANATAR in Pre-Treated HCC — Community Oncology Carousel
In VANTAGE, VANATAR demonstrated a manageable safety profile in Child-Pugh A patients with advanced HCC previously treated with sorafenib (L-C04). The most common adverse events were hand-foot syndrome, hypertension, and diarrhea (L-C06). While median PFS extended to 5.8 months versus 3.9 months (HR 0.68, p=0.0021) (L-C02), clinicians should consider dose modifications and supportive care strategies in community practice. Recommended starting dose is 400mg once daily (L-C05).

Pharmacy leadershipCost-of-care framing — caveats
Cost-of-care projections for VANATAR cannot be derived from VANTAGE alone — registrational trials don't reflect real-world utilization patterns. Post-market real-world evidence is required for total-cost-of-care modeling. The prescribing information and current formulary pricing are the starting point.
