Active clinical trials for "Acquired Immunodeficiency Syndrome"

To evaluate the safety of escalating doses of RMP-7 administered in persons with HIV infection and cryptococcal meningitis and to determine the MTD of the drug. To evaluate the pharmacokinetics, including cerebrospinal fluid (CSF) penetration, of amphotericin B when administered with RMP-7.

To evaluate the safety and tolerance of topical cidofovir (HPMPC) therapy for condyloma acuminatum in patients with HIV infection. To investigate whether topical HPMPC therapy can induce regression of condyloma acuminatum in patients with HIV infection.

To demonstrate a dosage regimen for intravenous itraconazole that produces a plasma concentration range comparable to that obtained after currently used oral dosages of itraconazole oral solution; and to obtain preliminary safety data in patients with advanced HIV disease.

The purpose of this study is to compare the effects of anti-HIV drug courses of different lengths in infants who became HIV infected at birth.

This is a 48-week study to evaluate the safety, tolerability, pharmacokinetics, and antiviral activity of an investigational regimen including FDA approved HIV drugs in HIV-infected pediatric subjects, ages 4 weeks to < 2 years old.

This study will determine the safety and side effects of two experimental HIV vaccines given in a "prime-boost" schedule. It will also monitor participants for the social impact of being in an HIV vaccine study (e.g., problems with insurance, health care, friends, family, employment, housing, and so forth). The vaccines are VRC-HIVDNA016-00-VP (called the DNA vaccine) and VRC-HIVADV014-00-VP (called the rAd vaccine). The DNA vaccine codes for four HIV proteins. The rAd vaccine is made using an adenovirus (a common virus that causes upper respiratory infections, such as the common cold) that has been modified to contain DNA that codes for three HIV proteins. These vaccines cannot cause HIV or adenoviral infections. The study will also see if the vaccines cause an immune response; if the injection of the DNA vaccine given using a needle and syringe is similar in safety and immune response to giving them with a needleless injection device called a Biojector 2000; if people who already have antibodies to adenovirus still have an immune response to rAd vaccine; and if there are social harms that result from participating in an HIV vaccine study. Healthy volunteers between 18 and 50 years of age may be eligible for this 42-week study. Candidates are screened with a medical history, physical examination, blood and urine tests (including pregnancy test for women), and questions regarding sexual behavior and other practices. Participants receive three injections (shots) of the DNA vaccine and one injection of the rAd vaccine. All injections are given into a muscle in the upper arm (alternating right and left arms with each injection), using a needle and syringe or the needleless Biojector 2000. The first vaccination is given the day of enrollment into the study, and the DNA vaccinations are given about 4 weeks apart from each other, with a minimum of 21 days between injections. The rAd "booster"vaccination is given at Week 24. Participants fill out a diary card at home for 5 days after each vaccination, recording their temperature and any symptoms. They come to the clinic for follow-up 3 days each DNA vaccine injection, and call or return again 7 days after each injection. They call a study nurse 1 or 2 days after the rAd injection. There are 15 to 18 clinic visits during the course of the study. At each visit, participants are checked for health changes or problems. Blood and urine samples are collected at some visits. Participants are periodically tested for HIV and asked questions about their sexual behavior and drug use and are counseled throughout the study on HIV risk reduction. They are also asked about any social effects they may have experienced as a result of their participation in this study.

The purpose of this study is to evaluate the dose-response relationship of antiviral activity after 48 weeks treatment with 3 different dose regimens of TMC278.

It is not known if anti-HIV treatment for recently infected patients improves long-term patient prognosis. The purpose of this study is to determine if a one year course of anti-HIV medications slows progression of HIV disease in adults recently infected with HIV. Study hypothesis: A one-year course of HAART administered during acute or early seroconversion may slow the progression of HIV infection.

This was a clinical trial in HIV infected patients with tuberculosis. The study assessed whether the addition of prednisolone, a type of steroid medication, to the standard treatment for tuberculosis improved immune and viral outcomes in the patients. The study demonstrated that prednisolone increased the CD4 cell count as was hoped, but the beneficial effect was short-lived and was gone within 4 months of stopping therapy. Therefore, the use of prednisolone for tuberculosis in HIV infected patients is not recommended at this time.

This study will evaluate the safety and immune system effects of infusing HIV-infected patients with multiple doses of lymphocytes (white blood cells) from their non-infected identical twin. It will determine whether the donated lymphocytes can improve immune function and reduce viral load in the infected twin. Identical twin pairs-one who is infected with HIV-1 and one who is negative for the virus-may be eligible for this study. Candidates will be screened with blood tests, a medical history and physical examination. Both twin participants will receive a tetanus booster shot, if needed. The non-infected twin will undergo apheresis to collect white blood cells. For this procedure, whole blood is collected, similar to the procedure for donating a unit of blood from a needle in the arm. The blood flows through a cell separator machine where the white cells are removed, and the rest of the blood (red cells, plasma and platelets) is returned to the donor through a catheter in the opposite arm. The collected lymphocytes will be given intravenously (through a vein) to the infected twin over a 60-minute period. This procedure-apheresis and infusions-will be repeated 4 days a week to complete one cycle. The cycles will be repeated about every 8 weeks for 6 cycles (about 1 year). The infected twin will have blood samples drawn on the first day of each cycle, 2 weeks after the beginning of each cycle, and 4 weeks after each cycle to evaluate immune status, viral load and other safety parameters. The frequency of these blood tests may change as the study progresses. The infected twin will also undergo apheresis immediately before each cycle of infusions and one month later to test the white cells for certain immune features. The number of apheresis procedures may be reduced as the study proceeds.
