Twin Moves: VRTX Rises On Kidney Disease Trial Results, MAZE Rallies Harder
Vertex Pharmaceuticals (VRTX) shares rose 3% after reporting positive trial results for inaxaplin in APOL1-mediated kidney disease (AMKD). The drug reduced protein leakage in urine by 42.7% for albumin and 44.7% for total protein in patients with modest proteinuria. Rival Maze Therapeutics (MAZE) shares jumped 25% on the read-through. Truist called the data a validation of APOL1 inhibition, estimating a market of over 100,000 patients and potential blockbuster sales for Maze's MZE829.
