Vanda's Novel Anti-Nausea Treatment Breaks 40-Year Market Gap, Attracting Multiple Bullish Analyst Calls

Landmark FDA Clearance for Travel Sickness Relief

The pharmaceutical landscape just shifted. After more than four decades without new options, the FDA has cleared Vanda Pharmaceuticals’ Nereus (tradipitant) for motion sickness prevention. This isn’t just another drug approval—it represents a meaningful gap-filler in a market where patients have been relying on decades-old alternatives. The move signals potential for travel sickness tablets to capture meaningful market share.

Data Tells the Story: Clinical Efficacy Speaks

What makes this approval compelling? The numbers. Vanda ran three clinical studies, including two Phase 3 trials conducted on moving vessels (Motion Syros and Motion Serifos), which form the foundation of this regulatory win.

In Motion Syros (365 participants), Nereus reduced vomiting to just 18.3–19.5% compared to 44.3% in the placebo group. Motion Serifos (316 participants) showed even sharper results: 10.4–18.3% vomiting rates on Nereus versus 37.7% on placebo. That translates to a 50–70% relative risk reduction—a statistically robust outcome that justifies the regulatory approval.

The drug demonstrated consistent safety profiles across trials, making it suitable for short-term use. The takeaway? Tradipitant has proven efficacy against motion-induced vomiting, validating years of development work.

Unexpected Growth Vector: GLP-1 Nausea Management

Here’s where it gets interesting. Beyond motion sickness, tradipitant showed promise in a controlled November 2025 trial targeting GLP-1-related side effects. Among patients taking GLP-1 therapies, tradipitant cut vomiting incidents to 29.3% versus 58.6% in the placebo arm—a 50% relative risk reduction.

This finding matters because GLP-1 adoption is booming. Any solution addressing treatment-related nausea could tap into a rapidly expanding patient pool seeking to maintain medication adherence.

Street View: Analysts Raising Targets

The investment community is taking notice. Raghuram Selvaraju at HC Wainwright bumped his price target from $20 to $22 (Buy rating), predicting the approval could trigger broader regulatory reassessment of tradipitant’s potential.

B Riley Securities’ Madison El-Saadi raised her target from $11 to $14, framing Vanda as a compelling turnaround narrative with two additional approvals potentially in the pipeline.

Cantor Fitzgerald’s Olivia Brayer maintained an Outperform stance at $11, noting that Nereus will likely command premium pricing—potentially exceeding $500 per eight-tablet bottle—compared to over-the-counter alternatives like dramamine. Pricing accessibility remains the critical variable.

Andrew Tsai at Jefferies stayed cautious with a Hold rating but lifted his target to $7.50 from $5, acknowledging gradual but meaningful uptake potential among patients dissatisfied with existing travel sickness tablets or those avoiding travel altogether.

The Commercialization Challenge

Here’s the reality: Vanda’s success hinges on penetration. Incumbent treatments are cheap and entrenched. Out-of-pocket costs will likely determine whether patients switch to Nereus despite superior efficacy. The company’s strategy of bundling eight tablets per bottle aims to improve affordability perception, though $500+ positioning suggests a premium positioning rather than mass-market disruption.

Uptake will likely emerge gradually as awareness builds, with early adoption concentrated among patients with prior adverse experiences or those seeking prescription-strength alternatives.

Current Momentum

As of latest trading, VNDA shares moved up 1.25% to $7.97, reflecting cautious optimism while the market digests the approval’s commercial implications.
