A kidney transplant milestone has Wall Street excited about Biogen
Biogen's (BIIB) stock rose 3% after JPMorgan upgraded it to Overweight, citing the potential of its kidney transplant drug felzartamab. The drug, in Phase 3 trials, targets antibody-mediated rejection, a condition with no approved treatment. JPMorgan estimates a $2B market for felzartamab, with data expected in 2027. The upgrade reflects growing investor interest in Biogen's pipeline beyond its Alzheimer's drug Leqembi.
