STEAP1 STEAP family member 1

ENSG00000164647 · protein coding · Open Targets profile

Does not function as a metalloreductase due to the absence of binding sites for the electron-donating substrate NADPH. Promotes Fe(3+) reduction when fused to the NADPH-binding domain of STEAP4. .

In 1 of 15 cancers, the evidence for STEAP1 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.

gnomAD loss of function constraint: o/e 0.8716899752616882 (upper bound 1.1822999715805054). Low values mean loss of function is poorly tolerated, a safety flag for inhibition.

Who runs trials of these drugs

No named investigators on registry trials of STEAP1's approved or late-stage drugs in the last three years.

No terminated, withdrawn or suspended trials of STEAP1's drugs are registered

Paediatric incentives and obligations for STEAP1's drugs

For vandortuzumab vedotin: 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.
