Coherus Oncology is a commercial-stage biopharmaceutical company focused on delivering biosimilar and innovative medicines. With a growing product portfolio and investor base, Coherus needed a modern, scalable website to reflect its leadership in the biopharma space and to support communication with patients, partners, and stakeholders. SIRO collaborated with branding and design partner 22 Fillmore to bring Coherus’ new digital presence to life—handling all website development, technical execution, and third-party integrations.
The Challenge
Coherus’ existing website no longer reflected the company’s strategic direction, pipeline advancements, or brand evolution. The internal team needed a flexible, easy-to-manage CMS and the ability to maintain detailed pipeline and investor-related content without relying heavily on developers. The site also needed to meet accessibility and compliance standards appropriate for a public company in the healthcare sector.

Our Approach
Working closely with 22 Fillmore, who led creative direction and visual design, SIRO translated a bold, responsive design system into a fully functional website. We focused on performance, flexibility, accessibility, and ease of content management—delivering a custom CMS tailored to Coherus’ content needs.
Custom Modular Pipeline Feature
We developed a dynamic, animated pipeline component that allows Coherus to visually present drug candidates across multiple therapeutic areas and development phases. This feature is fully CMS-driven, responsive, and can be updated or reordered by the internal team with no developer support.
Flexible CMS Architecture
The backend allows non-technical staff to manage complex content like leadership bios and pipeline data—without sacrificing design consistency.
Investor Relations Integration
We integrated a real-time investor relations press release feed and supplied Notified with front-end code to support investor communication and compliance.
Accessibility & Compliance
The site meets WCAG standards for accessibility and was built with long-term regulatory and performance needs in mind.
Results & Impact
The collaboration resulted in a highly successful website launch, providing numerous benefits for Coherus, helathcare providers, patients, and investors.
Improved User Experience
We achieved a 92/100 Google PageSpeed performance score, ensuring fast load times, smooth interactions, and optimized delivery across devices and browsers.
Enhanced Visibility & Reach
Following launch, Coherus experienced a 50% increase in Google Search impressions and clicks, indicating stronger search visibility and engagement.
Accessibility & Compliance
The site meets WCAG 2.1 “AA” compliance standards, ensuring a fully accessible experience for users with visual, motor, and cognitive impairments—crucial for a public life sciences company.
