Indivior Selects Havas as U.S. Integrated Agency of Record

Win reinforces Havas’ converged model, uniting creative, media, and experience to deliver next-level impact  

New York, NY (February 24, 2026) –  Havas today announced it has been selected as the U.S. Integrated Agency of Record for Indivior, a leader in long-acting injectable treatments for opioid use disorder (OUD) dedicated to delivering evidence-based treatment and advancing understanding of OUD as a chronic but treatable brain disease. Following a competitive, two-month review, Indivior chose Havas to lead integrated strategy, creative, media, and digital efforts across healthcare professional (HCP) and direct-to-consumer (DTC) audiences. 

The appointment represents a fully converged win for Havas, bringing together creative, media, and experience under a single operating model. It further validates Havas’ approach to helping clients solve complex business and societal challenges through integration, speed, and clarity. 

The partnership reunites Indivior with Havas following prior creative collaboration with Jacques NY (formerly Havas Tonic). 

“This win is a strong validation of our converged strategy in North America,” said 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.” 

“Challenges of this magnitude require more than disconnected campaigns,” said Chris Schnurman, Managing Director of Havas Life New York. “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.” 

Havas’ converged operating model enables teams to align insight, strategy, creativity, and activation – reducing fragmentation, optimizing performance in real time, and delivering more consistent engagement across complex healthcare ecosystems.
