ROR1 ROR family WNT receptor 1

ENSG00000185483 · protein coding · Open Targets profile

Has very low kinase activity in vitro and is unlikely to function as a tyrosine kinase in vivo (PubMed:25029443). Receptor for ligand WNT5A which activates downstream NFkB signaling pathway and may result in the inhibition of WNT3A-mediated signaling (PubMed:25029443, PubMed:27162350). In the inner ear, crucial for spiral ganglion neurons to innervate auditory hair cells (PubMed:27162350). Via IGFBP5 ligand, forms a complex with ERBB2 to enhance CREB oncogenic signaling (PubMed:36949068). {ECO:0000269|PubMed:25029443, ECO:0000269|PubMed:27162350, ECO:0000269|PubMed:36949068}.

In 2 of 15 cancers, the evidence for ROR1 comes mainly from inherited variants

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 0.24105000495910645 (upper bound 0.35370001196861267). 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 5 registry trials, updated in the last three years, of the most advanced drugs against ROR1 (cirmtuzumab), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

5 of 5 trials of drugs against ROR1 have sites only in United States

Registry trials of cirmtuzumab 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; 5 of 5 have all sites in one country.

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.

2 trials of drugs against ROR1 were stopped early

Terminated, withdrawn and suspended interventional trials of cirmtuzumab, newest update first, live from ClinicalTrials.gov. Each reason is quoted exactly as the registry gives it; we do not sort reasons into safety, efficacy or business. Dates are the last registry update. Showing the 2 most recent of 2.

Paediatric incentives and obligations for ROR1's drugs

For cirmtuzumab: 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.
