All-In AAV
home_gem_1_update 2-2

At Viralgen, we’re proud to be known for just one thing: Being a world leader in rAAV-based gene therapy manufacturing.

Earning the privilege to make your gene therapy

We’re all in on AAV; it’s all we do, all day, every day. And as an independently operated CDMO and subsidiary of AskBio, Viralgen delivers cGMP rAAV gene therapy manufacturing that grows as our clients do – from early construct optimization to small feasibility studies to full-on commercial campaigns.

We built our business on foundational science in AAVs and are home to the world’s largest manufacturing capacity dedicated to AAV for one reason: To get patients with genetic diseases a step closer to the therapies that can make a life-changing and, in some cases, life-saving, difference.

Why we’re trusted for AAV success

When your vision is to change the world with a gene therapy, you need to enlist a team that knows how to help that vision become reality for patients predictably, efficiently, and with the confidence that can only come from experience.

That’s precisely what you’ll find at Viralgen. In the last five years alone, we’ve been at the center of more global regulatory submissions using a single-platform process than other gene therapy manufacturer. Which means we can predict with clarity, adapt with surety, and advance with urgency. The bottom line of all that? Scale quickly. Future-proof your manufacturing. Start optimizing for cost of goods from day one. And mitigate downside risk.
