FDA Orphan Status for AbbVie Lung Cancer Drug
FDA has granted AbbVie an Orphan Drug Designation for veliparib, an oral poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitor, being investigated in combination with chemotherapy or radiation for treating advanced squamous non-small cell lung cancer. The company describes PARP as a naturally-occurring enzyme in the body that repairs damage to DNA in cells. “While this repair is a useful process to maintain the integrity of healthy cells, the same process may also help repair DNA in cancer cells, causing them to survive,” it says. “Researchers are investigating whether veliparib, a PARP inhibitor, in combination with DNA damaging therapies, such as chemotherapy or radiation, may lessen the repair of DNA damage in cancer cells, eventually causing some cells to die.”
