Phase II study of liposomal encapsulated daunorubicin in the treatment of AIDS-associated mucocutaneous Kaposi's sarcoma

Objective : To evaluate the efficacy and safety of liposomal encapsulated daunorubicin (DaunoXome) in the treatment of AIDS-associated mucocutaneous Kaposi's sarcoma. Design : A Phase II, multicentre, European, non-comparative, open study to assess the use of DaunoXome in patients with no prior anthracycline chemotherapy for Kaposi's sarcoma. The response rate, time to disease progression, and the incidence and severity of adverse events were documented. Setting : Hospital-based HIV units. Patients : Thirty HIV-seropositive patients with mucocutaneous Kaposi's sarcoma were enrolled and treated. Interventions : Treatment with DaunoXome at a dose of 40 mg/m 2 intravenously once every 2 weeks. Treatment with antiretroviral agents and prophylaxis of opportunistic infections where indicated. Results : Of the 30 evaluable patients, 22 patients (73%) achieved a partial response. Median time to treatment response was 30 days (range, 15-202). For patients with a partial response, median time to treatment failure was 153 days (range, 15-558). Patients received a median of 10 cycles (range, 1-44). Adverse events were minimal. The most common side effect was granulocytopenia in 16 patients (53%). Conclusion : DaunoXome is an effective and well-tolerated treatment for AIDS-associated mucocutaneous Kaposi's sarcoma and can be administered for prolonged periods. The myelosuppression can be managed by dose reductions and does not preclude the concurrent use of antiretroviral therapies.
