Viral Vector
Development & Manufacturing 

Accelerate your therapies’ journey from laboratory to patient.

The need for highly specific vector expertise is at the core of this scientific shift, as unique as the therapies you develop. There is no universal blueprint; your work deserves a custom-crafted strategy to swiftly and safely bring life-saving therapies to those in need.

The Scientist behind HEK293

While working in the Netherlands in the 1970s, genetic engineer and virologist Dr. Frank Graham developed the Calcium Phosphate Transfection technique and created the HEK293 cell line, now a cornerstone of gene therapy, vaccine development, and viral vector production.

Partnering with Us, You Accelerate Your Path to Market

In viral vector development, the journey from concept to clinical application demands a combination of scientific know-how and commercial experience, core expertise of the professionals working at NecstGen. We facilitate your translational journey within a state-of-the-art, GMP-compliant development and manufacturing facility, ensuring your project meets the highest standards.

Our team is adept at crafting meticulously tailored process designs to meet your therapies’ distinct needs. We are well-versed in the nuances of scaling up production to clinically relevant volumes, an essential step to meet increasing demand while maintaining the integrity of your product.

Our Product Expertise

Lentiviruses (LV)
Ideal for stable gene delivery, with a track record of safety and efficacy.

Adeno-Associated Viruses (AAV)
The vector of choice for targeting various tissues with minimal immune response.

Oncolytic Viruses
Harnessing the power of virotherapy to selectively target and destroy cancer cells.

Continuity through Product Development

Our commitment to scalability spans every trial phase in viral vector manufacturing, ensuring you can access state-of-the-art production capabilities when it matters most. From the crucial early stages of pre-clinical studies or toxicology material production, NecstGen provides robust support in developing and manufacturing viral vectors.

As your therapy progresses, we ensure the seamless transition from one phase to the next, providing reliable and high-quality viral vector supplies from pre-clinical to Phase III clinical trials.

This continuity is the cornerstone of our service, guaranteeing not just consistency in the product but also confidence in the process. It allows our scientific partners to focus on the pivotal task of advancing their therapies through the trial phases toward ultimate regulatory approval and patient application.
