GPC3 glypican 3

ENSG00000147257 · protein coding · Open Targets profile

Cell surface proteoglycan (PubMed:14610063). Negatively regulates the hedgehog signaling pathway when attached via the GPI- anchor to the cell surface by competing with the hedgehog receptor PTC1 for binding to hedgehog proteins (By similarity). Binding to the hedgehog protein SHH triggers internalization of the complex by endocytosis and its subsequent lysosomal degradation (By similarity). Positively regulates the canonical Wnt signaling pathway by binding to the Wnt receptor Frizzled and stimulating the binding of the Frizzled receptor to Wnt ligands (PubMed:16227623, PubMed:24496449). Positively regulates the non-canonical Wnt signaling pathway (By similarity). Binds to CD81 which decreases the availability of free CD81 for binding to the transcriptional repressor HHEX, resulting in nuclear translocation of HHEX and transcriptional repression (By similarity). Inhibits the dipeptidyl peptidase activity of DPP4 (PubMed:17549790). Plays a role in limb patterning and skeletal development by controlling the cellular response to BMP4 (By similarity). Modulates the effects of growth factors BMP2, BMP7 and FGF7 on renal branching morphogenesis (By similarity). Required for coronary vascular development (By similarity). Plays a role in regulating cell movements during gastrulation (By similarity). {ECO:0000250|UniProtKB:Q6V9Y8, ECO:0000250|UniProtKB:Q8CFZ4, ECO:0000269|PubMed:14610063, ECO:0000269|PubMed:16227623, ECO:0000269|PubMed:17549790, ECO:0000269|PubMed:24496449}.

In 14 of 15 cancers, the evidence for GPC3 comes mainly from mutations found in tumours

Each row is a cancer, strongest overall evidence first. The two dots show how strong the inherited (germline) and tumour-mutation (somatic) evidence is; the line between them is the gap.

Scores run from 0 (no evidence) to 1 (strongest). A missing dot at 0 means Open Targets holds no evidence of that kind. Source: Open Targets Platform, fetched live.

gnomAD loss of function constraint: o/e 0.08715999871492386 (upper bound 0.22527000308036804). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

Principal investigators and study chairs on 1 registry trials, updated in the last three years, of the most advanced drugs against GPC3 (codrituzumab), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

1 of 1 trials of drugs against GPC3 have sites only in United States

Registry trials of codrituzumab updated in the last three years, counted by the country group of their listed sites. A trial with sites in several groups counts in each; 1 of 1 have all sites in one country.

Sites only in this groupSites here and elsewhere
United StatesUnited States: 1 trials with sites only hereUnited States: 0 trials with sites here and elsewhere1

Site counts are not patients per country, and trials registered only outside ClinicalTrials.gov are not covered. Where sites are is a fact about the record, not a judgement of its quality. Europe is the EU and EEA, the UK and Switzerland. Source: ClinicalTrials.gov, fetched live.

No terminated, withdrawn or suspended trials of GPC3's drugs are registered

Paediatric incentives and obligations for GPC3's drugs

For codrituzumab: what EMA and FDA publish about paediatric plans, orphan status and pediatric approvals, and how many registered studies take children. Each line is a yes, no or not published fact from the record linked under it; none of it is a forecast.

Rare pediatric disease voucher. FDA, content current as of 29 Apr 2026: “As of February 3, 2026, enactment of the Consolidated Appropriations Act, 2026, the rare pediatric disease PRV program will sunset after September 30, 2029. FDA may not award any PRVs under this program after September 30, 2029.” Voucher sale prices are not shown here; they appear only as company-reported news.
