Drug Therapies in Clinical Studies

Rusfertide (PTG-300) is a hepcidin mimetic currently being studied as a treatment for polycythemia vera (PV).


JNJ-2113 (formerly known as PN-235) is an oral peptide IL-23 receptor antagonist currently being studied in moderate-to-severe psoriasis and ulcerative colitis.


This reflects our corporate policy on providing access to our new investigational medicines before they are fully approved for use on prescription.
