Filter by:To evaluate the safety, tolerability, and efficacy of long term, bi-weekly administration of aerosol pentamidine when used as a prophylactic agent in patients who have had at least two or more episodes of AIDS-associated Pneumocystis carinii pneumonia (PCP).
The primary objective of the study is to evaluate the effectiveness of l-leucovorin in preventing toxicity from high dose trimethoprim / sulfamethoxazole (TMP / SMX) used as a therapy for Pneumocystis carinii pneumonia (PCP) in patients with AIDS.
To compare the safety of atovaquone (566C80) with intravenous (IV) pentamidine for the treatment of mild to moderate Pneumocystis carinii pneumonia (PCP) in AIDS patients who are intolerant of therapy with trimethoprim / sulfamethoxazole (TMP / SMX) by comparing the incidence of premature discontinuation of therapy due to toxicity. To compare the efficacy of 566C80 with intravenous (IV) pentamidine for the treatment of mild to moderate PCP in the same population.
To facilitate provision of atovaquone (566C80) to patients who have mild to moderate Pneumocystis carinii pneumonia (PCP) and are intolerant and/or unresponsive to trimethoprim / sulfamethoxazole (TMP / SMX ); to monitor serious adverse events attributable to 566C80.
To facilitate provision of atovaquone (566C80) to patients who have severe Pneumocystis carinii pneumonia (PCP) and are intolerant and/or unresponsive to trimethoprim / sulfamethoxazole ( TMX / SMX ); to monitor serious adverse events attributable to 566C80.
To compare the safety and efficacy of aerosolized pentamidine and dapsone in the prevention of Pneumocystis carinii pneumonia (PCP) in high-risk HIV-infected patients who are intolerant to trimethoprim and/or sulfonamides. Both aerosolized pentamidine and dapsone have been shown to prevent PCP, but both drugs cause side effects. This study attempts to determine which drug is more efficacious as prophylaxis against PCP in patients who cannot tolerate trimethoprim/sulfamethoxazole.
Primary: To compare the pharmacokinetics of biweekly and monthly dose regimens of intravenous pentamidine in HIV-infected infants and children who require PCP prophylaxis and who are intolerant to oral trimethoprim - sulfamethoxazole. To determine the safety and tolerance of these regimens in this patient population. Secondary: To obtain information on the rate of PCP breakthrough in infants and children receiving parenteral pentamidine prophylaxis. Prophylaxis against Pneumocystis carinii pneumonia is recommended for all HIV-infected children considered to be at high risk. In children younger than 5 years of age with intolerance to trimethoprim - sulfamethoxazole, parenteral pentamidine may be a successful alternative.
To determine the safety and effectiveness of an investigational drug trimetrexate (TMTX) with leucovorin rescue (LCV) in the treatment of Pneumocystis carinii pneumonia (PCP) in patients who have AIDS, are HIV positive, or are at high risk for HIV infection, and who have demonstrated serious adverse effects from the conventional therapies for PCP. The drugs usually used to treat PCP in AIDS patients (trimethoprim / sulfamethoxazole and pentamidine) have had to be discontinued in many patients because of severe adverse effects. Currently there are no proven alternatives to these drugs. TMTX was chosen for this trial because it has been found to be very active against the PCP organism in laboratory tests. In a preliminary trial, TMTX in combination with LCV has been effective against PCP with fewer and less severe adverse effects.
To compare the safety and effectiveness of an investigational drug therapy (trimetrexate plus leucovorin calcium) with that of conventional therapy (sulfamethoxazole-trimethoprim) in the treatment of moderately severe Pneumocystis carinii pneumonia (PCP) in patients who have AIDS, are HIV positive, or are at high risk for HIV infection. New treatments are needed to reduce the mortality rate from PCP in AIDS patients and to reduce the high relapse rate found after conventional therapy. Trimetrexate (TMTX) was chosen for this trial because it was found to be much more potent than sulfamethoxazole/trimethoprim (SMX/TMP) against the PCP organism in laboratory tests. Also TMTX, in combination with leucovorin (LCV), did not cause severe toxicity in a preliminary trial. It is believed that TMTX will be more effective in treating PCP and in preventing a recurrence of PCP.
To compare the safety and effectiveness of an investigational drug therapy (trimetrexate plus leucovorin calcium) with that of conventional therapy (sulfamethoxazole-trimethoprim) in the treatment of moderately severe Pneumocystis carinii pneumonia (PCP) in patients who have AIDS, are HIV positive, or are at high risk for HIV infection.
