How does Kyprolis work?

  • Kyprolis is a member of the drug class known as proteasome inhibitors, which function by targeting on the cancer cells’ proteasomes3Overview| Researched based study from
  • By inhibiting these proteasomes, Kyprolis causes cell death in cancer cells, effectively slowing the formation of tumors by impacting all cells that divide quickly4Overview| Researched based study from
