Randomized Controlled Trial Clinical Trial
Prospective randomized Phase II trial of pegylated doxorubicin in the management of symptomatic hormone-refractory prostate carcinoma.
Liposomal encapsulation of doxorubicin has been shown to reduce nonspecific delivery of this agent to normal tissue and to increase specific delivery to malignant cells. On the basis of doxorubicin's demonstrated clinical efficacy against hormone-refractory prostate carcinoma (HRPCA), the authors conducted a prospective, randomized Phase II clinical trial to evaluate the feasibility, toxicity, and therapeutic efficacy associated with the pegylated form of this agent. ⋯ Pegylated liposomal doxorubicin yielded a noteworthy objective palliative response rate and a mean survival of 13 months for patients with symptomatic HRPCA. The dosage tested in the current study should be used in future Phase II and Phase III trials of pegylated liposomal doxorubicin-containing combination regimens for patients with HRPCA.
