Pfizer’s Xalkori OK’d for Myofibroblastic Tumors
FDA has approved a Pfizer supplemental NDA for Xalkori (crizotinib) for adult and pediatric patients with unresectable, recurrent, or refractory inflammatory anaplastic lymphoma kinase (ALK)-positive myofibroblastic tumors (IMT). Approval was based on data from two single-arm, open-label trials that included 14 pediatric patients from trial ADVL0912 (NCT00939770) and seven adult patients from trial A8081013 (NCT01121588) with unresectable, recurrent, or refractory ALK-positive IMT, with both measuring objective response rate, according to an agency release.
Of the 14 pediatric patients treated, a total of 12 patients (86%) experienced an objective response, which was assessed by an independent review committee, the agency says. For the seven adult patients, five patients had objective responses.
