Anti-CD19 Recombinant Immunotoxin (B4-Ricin) (CAT#: BioBet-IT012Z) Datasheet

Target
CD19
IT Type
Antibody-based IT
Description
The immunotoxin includes a mouse anti-CD19 antibody (B4) coupled to a modified form of ricin (a phytotoxin). In multiple phase I and phase II studies of this immunotoxin, the desired response has been seen in many patients with tolerable and reversible toxicity.
Indication
Refractory B-cell malignancies; B-cell Leukemia/Lymphoma
Classification
Immuntoxin; biobetter
Construction
B4-Ricin

Cooperation Seeking

Creative Biolabs is interested in collaborating with potential partners (include but not limit to major pharma or biotech firms) to further co-develop our ADCC/CDC-enhanced antibodies or immutoxins. For commercial partners interested in our therapeutic biobetter product, Creative Biolabs welcomes collaboration.
Here are two ways for your choice, and please contact us for more details.
1) Collaborate with us and co-develop the programs from discovery phase to IND enabling. Costs will be shared.
2) Become a licensed candidate of our programs.
Looking forward to cooperating with you in the near future.

Toxic MOA
Ricin toxin A chain (RTA) is an N-glycoside hydrolase composed of 267 amino acids. Ricin is a toxalbumin, a biological toxin whose mechanism of action is inhibition of protein synthesis (manufacture of proteins) in eukaryotic cells; cell death results from the absence of proteins.

The antibody portion mediated selective binding to target cells, while the toxin portion mediated translocation into the cytosol and subsequent cell killing.
