This program aims to develop anti-GPC3 therapeutic monoclonal antibodies for immuno-oncology.
Glypicanin-3 (GPC3) is a heparan sulfate proteoglycan, expressing mostly in hepatocellular carcinoma (HCC), ovarian clear cell carcinoma, melanoma, lung squamous cell carcinoma, hepatoblastoma, kidney blastoma, and some pediatric cancers. To note, GPC3 is currently used as a diagnostic biomarker to distinguish HCC from normal liver tissues, benign liver tumors, and other types of metastatic cancer, highlighting the rationale for GPC3-based tumor immunotherapy.
GPC3 can be immobilized on the cell surface by glycosylphosphatidylinositol anchors. GPC3 can be expressed in a variety of tissues during embryonic development. Beyond that life state, it is a highly tumor-specific antigen in which expression is severely inhibited in most adult tissues.

Here are some published data about GPC3 working as a potential target for cancer immunotherapy.

Trial | Patients | ID |
A randomized, placebo-controlled, double-blind, multicenter phase II trial of intravenous GC33 at 1,600 mg Q2W in previously treated patients with unresectable advanced or metastatic HCC | Histologically confirmed HCC | NCT 01507168 |
A phase I dose escalation and cohort expansion study of ERY974, an anti-GPC3/CD3 bispecific antibody, in patients with advanced solid tumors | Patients with GPC3-positive advanced solid tumors not amenable to standard therapy or for which standard therapy was not available or not indicated | NCT 02748837 |

Creative Biolabs has extensive knowledge of end-to-end program development. For each program, we are committed to delivering the final complete program to our clients within 1.5 years before entering the IND stage.
Creative Biolabs is looking for potential partners (include but not limit to major pharma or biotech firms) to develop anti-GPC3 therapeutic monoclonal antibody programs together. Our scientists are dedicated to bringing together years of valuable experience to our partner and achieve a meaningful partnership together. For any partners interested in our Next-IO™ programs, 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 the discovery phase to IND enabling. Costs will be shared.
2) Become a licensed candidate for our programs.
With our quality control protocol and knowledge of global regulatory requirements, we can help our partners further their programs with more chance to succeed. Look forward to cooperating with you in the near future.
