Frame the target before identity details

Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-13

Complement C5 shows approved-linked disease relevance led by paroxysmal nocturnal hemoglobinuria. 5 more disease programs remain visible in the same review block. 6 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P01031. Start with paroxysmal nocturnal hemoglobinuria, then reuse UniProt P01031 as the stable protein anchor across project notes and exports.

Disease program
paroxysmal nocturnal hemoglobinuria

Complement C5 shows approved-linked disease relevance led by paroxysmal nocturnal hemoglobinuria. 5 more disease programs remain visible in the same review block. 6 linked drugs remain visible in the same block.

Start review with paroxysmal nocturnal hemoglobinuria because it currently carries approved-linked support. Linked drugs include CROVALIMAB, ECULIZUMAB, NOMACOPAN, POZELIMAB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
