A Phase I Study of the Combination of Recombinant GM-CSF, AZT, and Chemotherapy (ABV) (Adriamycin, Bleomycin, Vincristine) in AIDS and Kaposi's Sarcoma

Summary

To determine the safety as well as the most effective dose of sargramostim (GM-CSF; granulocyte-macrophage colony stimulating factor) that will prevent the side effects caused by the combined use of zidovudine (AZT) and various doses of cancer-fighting drugs (doxorubicin, bleomycin, and vincristine) in AIDS patients with Kaposi's sarcoma (KS). Patients included in this study have KS, which is a type of cancer that occurs in nearly 20 percent of patients with AIDS. AIDS patients with extensive KS require treatment with effective cytotoxic (anti-cancer) agents to reduce the tumor size and with antiretroviral agents such as AZT to prevent or ameliorate the development of opportunistic infections. Due to the significant toxic effect of both cytotoxic and antiviral agents on the bone marrow where new blood cells are generated, the combination of these agents is expected to result in complications such as granulocytopenia (very low granulocyte counts). Hematopoietic growth factors such as GM-CSF may reduce the severity and duration of marrow suppression. This may improve survival. Clinical trials of GM-CSF in HIV infected individuals with or without granulocytopenia have shown that the progenitor cells (early blood cells) are responsive to GM-CSF.
