Active clinical trials for "Pneumonia"

The study will assess the clinical efficacy at Day 14-21 (Test of Cure), 14-21 days after starting the study drug; those subjects from whom a baseline pathogen is identified will also be assessed for bacteriologic response. All subjects who receive 1 dose of study medication will be assessed for safety.

The purpose of this study is to determine the efficacy of addition of corticosteroid therapy to antibiotics in patient admitted with Community-acquired pneumonia. The hypothesis is: Prednisolone in combination with antibiotic treatments is effective in improving clinical outcome in patients hospitalized with CAP.

To compare the efficacy and safety of tigecycline with those of levofloxacin in the treatment of subjects with CAP requiring hospitalization. The co-primary efficacy endpoints in the study will be the clinical response in the clinically evaluable population and the clinical response in the clinical modified intent-to-treat population at the TOC visit. The primary efficacy analyses will first determine whether tigecycline is noninferior to levofloxacin. If tigecycline is found to be noninferior, the analyses will determine whether tigecycline is statistically better than levofloxacin.

To evaluate the safety of the combination of trimetrexate glucuronate (TMTX) and dapsone with leucovorin protection versus trimethoprim/sulfamethoxazole (TMP/SMX) in patients with AIDS and moderately severe Pneumocystis carinii pneumonia (PCP). To determine the pharmacokinetic parameters of TMTX, leucovorin, and dapsone and of TMP/SMX when given to patients with AIDS and moderately severe PCP.

To determine which of 2 doses of dapsone is effective prophylaxis for Pneumocystis carinii pneumonia (PCP) in patients with oral thrush or hairy leukoplakia and less than 400 CD4 lymphocytes per mm3. To determine whether the long-term toxicities associated with daily dapsone in this population are tolerable.

The purpose of this study is to determine the effects of etanercept, and define the toxicity, when administered to patients with acute non-infectious lung injury (idiopathic pneumonia syndrome, IPS) and with subacute pulmonary dysfunction after allogeneic stem cell transplantation.

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 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.

To determine if the drug combination sulfamethoxazole-trimethoprim (SMX-TMP), given by mouth, and the drug pentamidine (PEN), given by inhaled aerosol, are effective in preventing a relapse of Pneumocystis carinii pneumonia (PCP) when they are given to patients who have recovered from a first episode of PCP and are being given zidovudine (AZT) to treat primary HIV infection. AZT prolongs survival in patients with AIDS and decreases the occurrence of opportunistic infections such as PCP. However, PCP recurs in about 43 percent of patients receiving AZT, indicating a need for other treatments to reduce the relapse rate. The two medications to be tested in this study, SMX/TMP and aerosolized PEN, have also been partially effective in preventing recurrence of PCP. It is hoped that the combination of AZT with these medications will be more effective than AZT or one of the medications alone.

To determine the maximum tolerated dose (MTD) of WR 6026 in HIV-infected patients. To determine whether any unexpected toxicities are caused by WR 6026 in HIV-infected patients. To determine whether there is additional toxicity when WR 6026 is given for 21 days rather than 14 days. To further investigate the pharmacokinetics and pharmacodynamics of WR 6026, and in particular to examine potential correlations between the area under the concentration-time curve and methemoglobinemia or other toxicities. In recent animal studies, WR 6026 demonstrated inhibitory activity against Pneumocystis carinii pneumonia (PCP). This study will assess the safety and tolerance of this drug in HIV-infected patients who do not have PCP.
