All Clinical Trials for PENTAMIDINE ISETHIONATE
| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00000707 ↗ | Aerosols in the Treatment of Asymptomatic Pneumocystis Pneumonia: A Pilot Study Assessing the Effectiveness of Aerosolized Pentamidine as Treatment of Subclinical Pneumocystis Infection in Patients With No Clinical Symptoms | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | N/A | 1969-12-31 | To confirm the ability of pulmonary (lung) function testing (PFT) to detect Pneumocystis carinii pneumonia (PCP) before the development of clinical symptoms and to determine if pentamidine (PEN), a drug used in treating PCP, can be given effectively as an aerosol (inhaled mist). Other goals include the measurement of the actual amount of PEN that reaches the lung, and to determine if close clinical observation is safer and as effective as drug therapy for the prevention of subsequent episodes of PCP. Many AIDS patients develop PCP, but the effectiveness of early diagnosis and treatment of PCP is not known. The effectiveness of PEN may be improved if treatment is begun when the parasite burden (the number of organisms in the lung) is still small, and before respiratory symptoms appear. If PFT of HIV-infected patients is able to identify patients in the early stages of infection, outpatient treatment of these patients offers a possible alternative to the expense and toxicity of continuous preventive therapy of all high-risk patients. |
| NCT00000715 ↗ | A Controlled Trial Comparing the Efficacy of Aerosolized Pentamidine and Parenteral/Oral Sulfamethoxazole-Trimethoprim in the Treatment of Pneumocystis Carinii Pneumonia in AIDS | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 1969-12-31 | To compare the safety and effectiveness of drug therapy with aerosolized pentamidine (PEN) with that of conventional therapy, sulfamethoxazole plus trimethoprim (SMX/TMP) in the treatment of Pneumocystis carinii pneumonia (PCP) in patients who have AIDS, are HIV positive, or are at high risk for HIV infection. New treatments are needed for PCP, a common lung infection in patients with AIDS, because many patients treated with the two standard treatments, PEN given by injections and SMX/TMP, have had adverse effects that required a change in treatment. There is also a high relapse rate after the standard treatments. Preliminary experiments in humans suggest that aerosolized PEN is as effective as the standard treatments for PCP, and causes few adverse effects. |
| NCT00000722 ↗ | Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | N/A | 1969-12-31 | To compare the use of pentamidine aerosol (inhaled mist) with the standard intravenous method of administration in patients with AIDS related Pneumocystis carinii pneumonia (PCP), to measure the amount of pentamidine aerosol that actually reaches the lung, and to see if close clinical observation is safer and as effective as drug therapy in the prevention of PCP recurrences. To compare the efficiency of 2 nebulizers - the Respirgard II nebulizer and the Cadema Aerotech II nebulizer. Aerosolized pentamidine was as effective as intravenous pentamidine in treating PCP in animals. More of the pentamidine reached the lungs and less was found in the liver and kidney after pentamidine was given by aerosol than after an intravenous injection. This suggests that the toxicity of pentamidine may be less if given by aerosol than if given by the intravenous route. |
| NCT00000727 ↗ | A Controlled Comparative Trial of Sulfamethoxazole-Trimethoprim Versus Aerosolized Pentamidine for Secondary Prophylaxis of Pneumocystis Carinii Pneumonia in AIDS Patients Receiving Azidothymidine (AZT) | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 1969-12-31 | 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. |
| NCT00000730 ↗ | Comparison of Three Treatments for Pneumocystis Pneumonia in AIDS Patients | Terminated | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 1969-12-31 | This study compares three different therapies for treatment of refractory Pneumocystis carinii pneumonia (PCP) in patients with AIDS. "Refractory" means that the patient has failed to respond to at least 4 days of treatment with either of two standard therapies: (1) sulfamethoxazole/trimethoprim (SMX/TMP) or (2) pentamidine (PEN). This study compares therapy with trimetrexate (TMTX) and leucovorin (LCV) to standard therapy and standard therapy plus high-dose steroids (methylprednisolone). The purpose is to find better and safer forms of treatment for PCP in AIDS patients. There is at present no scientific information about the best treatment for an AIDS patient with PCP who is not improving while receiving the standard therapies (SMX/TMP or PEN). New drug treatments are available, including steroid therapy and TMTX, but there is no information proving that these new treatments work better than the standard therapies. |
| NCT00000974 ↗ | A Study of Two Forms of Pentamidine in HIV-Infected Children Who May Have Pneumocystis Carinii Pneumonia | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 1 | 1969-12-31 | To evaluate the delivery of a single dose of aerosolized pentamidine to children; to evaluate the tolerance of pentamidine administration by mask; to compare intravenous pentamidine first dose pharmacokinetics (blood levels) in children with information previously collected on adults; and to compare plasma pentamidine levels in children after an aerosolized treatment with levels previously collected on adults. Pneumocystis carinii pneumonia (PCP) is the most common serious infection in children with AIDS and is associated with a high death rate. Current approved treatment includes intravenous trimethoprim - sulfamethoxazole (TMP / SMX) and intravenous pentamidine, which are both effective in treatment of the first episode of PCP pneumonia. However, both therapies have a 50 percent or greater incidence of adverse reactions. Because of serious toxicities, drug treatment has had to be discontinued. Animal studies show that aerosolized pentamidine (pentamidine given through inhalation) is as effective as intravenous pentamidine. It is hoped that the aerosolized route will be less toxic than intravenous pentamidine. The study is the first step in evaluating the delivery of aerosolized pentamidine to children. |
| NCT00000991 ↗ | A Study of Three Drugs Plus Zidovudine in the Prevention of Infections in HIV-Infected Patients | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 3 | 1969-12-31 | To evaluate and compare 3 anti-pneumocystis regimens plus zidovudine (AZT) in persons with HIV infection and T4 cell count less than 200 cells/mm3. All persons completing at least 8 weeks of therapy on 081 will be offered the opportunity to participate in the nested study (ACTG 981) of systemic antifungal therapy (fluconazole) versus local therapy (Clotrimazole) for the prevention of serious fungal disease. Persons with HIV disease who are receiving AZT are at risk for PCP, toxoplasmosis, bacterial pneumonia, and other serious infections. It is therefore important to find drugs that can be given along with AZT to control these infections. Aerosolized pentamidine (PEN) has been shown to be useful in preventing PCP and is expected to lower the 2-year risk of PCP. Both sulfamethoxazole/trimethoprim (SMX/TMP) and dapsone probably also provide effective preventive treatment against PCP, and both may be useful in preventing toxoplasmosis and extrapulmonary pneumocystosis. |
