TNFSF13B TNF superfamily member 13b

ENSG00000102524 · protein coding · Open Targets profile

Cytokine that binds to TNFRSF13B/TACI and TNFRSF17/BCMA. TNFSF13/APRIL binds to the same 2 receptors. Together, they form a 2 ligands -2 receptors pathway involved in the stimulation of B- and T- cell function and the regulation of humoral immunity. A third B-cell specific BAFF-receptor (BAFFR/BR3) promotes the survival of mature B- cells and the B-cell response. .

1 of the 7 drugs recorded against TNFSF13B is approved, and 4 more reached Phase 3

Each band is a group of drugs. It runs from the kind of drug on the left to the furthest stage that drug has reached in any disease on the right. Thicker bands mean more drugs.

Approved bands are highlighted. Withdrawn means the drug was pulled from the market or from development. A combined phase counts as the later one (Phase 1/2 is shown as Phase 2). Hover a band for the drug names. Source: Open Targets Platform, fetched live.

TNFSF13B: inherited and tumour-mutation evidence across 15 cancers

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 0.27458998560905457 (upper bound 0.4954499900341034). 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 44 registry trials, updated in the last three years, of the most advanced drugs against TNFSF13B (belimumab, blisibimod, atacicept, tabalumab, tibulizumab, rozibafusp alfa, briobacept), ranked by Phase 2+ trials. Live from ClinicalTrials.gov.

14 of 44 trials of drugs against TNFSF13B have sites only in United States

Registry trials of belimumab, blisibimod, atacicept, tabalumab, tibulizumab, rozibafusp alfa, briobacept 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; 30 of 44 have all sites in one country.

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.
