Under accelerated approval, DOXIL was indicated for the treatment of metastatic ovarian cancer in patients with disease that was refractory to both paclitaxel- and platinum-based chemotherapy regimens. This approval was based on tumor response rates from three Phase II studies. According to the terms of the accelerated approval, Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD) completed a randomized Phase III clinical study to formally demonstrate the drug's clinical benefit in patients with relapsed ovarian cancer. In March 2004, J&JPRD submitted a supplemental new drug application (sNDA) based on data from the Phase III study.
"The Phase III data provide evidence of the product's clinical benefit for patients with relapsed ovarian cancer," commented Alan N.

In the randomized, multi-center, open-label, Phase III study, 474 patients with recurrent epithelial ovarian cancer were randomly assigned to receive either DOXIL 50 mg/m2 every 28 days or topotecan HCl 1.5 mg/m2/day for five consecutive days every 21 days. A total of 239 patients received DOXIL; 235 patients received
