Havas named integrated agency for Indivior

Havas has been appointed U.S. Integrated Agency of Record for Indivior, a leader in long-acting injectable treatments for opioid use disorder (OUD). Following a competitive two-month review, Havas will lead integrated strategy, creative, media and digital efforts across healthcare professional (HCP) and direct-to-consumer (DTC) audiences.

The win reinforces Havas’ converged operating model, uniting creative, media and experience under a single framework. The approach aims to reduce fragmentation, accelerate decision-making, and deliver consistent engagement across complex healthcare ecosystems.

Greg James, CEO, Havas Media Network North America: "Indivior didn’t come to us for an advertising solution – they came to us for integration. By uniting creative, media, and experience around a single strategy, we’re able to help clients navigate complexity, move faster, and deliver meaningful impact. That’s exactly how we support our clients’ growth today."

Chris Schnurman, Managing Director, Havas Life New York: "Challenges of this magnitude require more than disconnected campaigns. Our role is to help Indivior bring clarity, credibility, and consistency to every touchpoint – supporting providers and patients with work that is human, respectful, and effective."

The partnership reunites Indivior with Havas following previous creative work with Jacques NY (formerly Havas Tonic). Havas’ integrated model aligns insight, strategy, creativity and activation to deliver scalable, real-time performance improvements and more cohesive engagement across audiences.
