Molecules in the clinic

Plug-and-play multispecific antibody development. Exceptional quality. Transparent terms.

Most antibody platforms push engineering complexity into the variable domains, so every new molecule brings new chain pairing, purification, and manufacturing risk. If a lead fails late for something that should have been caught early, you’re back to zero.

Our B-Body® and T-Body™ platforms solve the hard engineering in the constant domains, so your variable domains plug in and go.

About B-Body About T-Body
Screen hundreds of combinations in the final therapeutic format.
Ready for CLD and CMC.
Transparent pricing, clear path to licensing, and straight-forward agreements.
What this means in practice

Screen 288+ bispecific combinations in one campaign, not just a handful

>99% of combinations pass purity and yield criteria in the B-Body 1x1 format in at least one orientation

Every molecule screened in the final format, so there’s no reformatting later

Standard mAb-like purification processes allowing same process from discovery through manufacturing

Three molecule types. Start where your program is.

Pick the service that matches your target biology. Each path offers Discovery (we find the antibodies) or Expression (you bring the variable domains).

DEV

Extensive developability capabilities

Expression and purity, thermal stability, self-association, aggregation, solubility, immunogenicity risk, viscosity, each measured with a validated technique. The full developability data sits behind every lead candidate we hand off.

Why Invenra What makes us different in antibody development

High purity & yield

The platform just works.

In a single experiment, we tested 144 commercial-stage antibody combinations in both orientations using the B-Body platform. Over 99% passed purity and yield specs in at least one orientation.

Clear pricing

52 views of cancer

First in class trispecific ADC molecules

Our 52 views project goes beyond developing trispecific ADCs and making these novel therapeutics available to partners. We are creating a one-of-a-kind playing card deck that celebrates the creativity, resilience, and spirit of people whose lives have been touched by cancer. Each of the 52 cards will feature original artwork from a cancer patient, survivor, or immediate family member, making every card a unique view of the human experience with this disease.

From the beginning, we have always striven to be Best in Class. When we developed the B-Body platform, we kept innovating until we outperformed all the known competitors. The same is true for our T-Body platform. And when you start with an excellent platform, it makes everything else easier."
