51 Clinical Trials for Various Conditions
This study is being conducted to determine if the uptake of anti-HIV medication, called Genvoya®, at different time-frames, is different at several body sites, including mucosal tissues. This medication might be considered for on-demand PEP regimens in the future.
This study is being conducted to determine if the uptake of anti-HIV medications called Genvoya® and darunavir is different at several body sites, including mucosal tissues.
The study is being conducted to evaluate whether African potato, an herbal medicine, can be used together with anti-HIV medicines without affecting the amounts of the anti-HIV medicines in the blood. African potato is an African herbal medicine widely used in Africa, particularly sub-Saharan Africa. Although it has not been proven, it is believed to help boost the immune system. Similar studies have been done on herbal medicines especially those that are used in developing countries. In some cases, the herbal treatments can affect the blood levels of other medicines when the medicines are used together. This study will measure the effect of African potato on lopinavir/ritonavir (Kaletra®), a common anti-HIV medicine. Lopinavir/ritonavir is approved by the United States Food and Drug Administration (FDA). The information obtained from this study will tell us if African potato and anti-HIV treatments can be used together to treat HIV infected patients in Africa and other resource poor regions.
The primary objective of this study is to evaluate the efficacy of lenacapavir (formerly GS-6207) containing regimens in people living with human immunodeficiency virus (HIV) (PLWH).
To investigate the pharmacokinetic drug-drug interaction potential of fixed dose antiretroviral therapies, i.e. ATRIPLA, COMPLERA, STRIBILD, TRIUMEQ, or any approved antiretroviral protease inhibitor in combination with (preferably) TRIUMEQ, on the exposure to riociguat in HIV patients on a stable dose of one of these therapies. • To Assess the safety and tolerability of riociguat treatment in combination with these fixed-dose antiretroviral therapies.
The purpose of this study is to learn more about the safety and tolerability of etravirine. Etravirine is a type of non-nucleoside reverse transcriptase inhibitor (NNRTI) which has shown high activity against wild-type human immunodeficiency virus (HIV-1), and HIV strains resistant to other non-nucleotide agents.
The purpose of the study is to determine in healthy volunteers whether certain anti-HIV medications (lopinavir/ritonavir and efavirenz) affect the drug levels of certain anti-malarial medications (artesunate/ amodiaquine and artemether/ lumefantrine) and vice versa. Since these drugs are degraded using overlapping pathways in the liver, it is predicted that changes in both drug level and overall drug exposure will be observed.
The main objective of this study is to observe the long-term safety of elvitegravir (EVG) boosted with ritonavir (RTV) in combination with other antiretroviral (ARV) agents in participants who have completed a prior EVG+RTV treatment study.
This study will determine if blood levels of anti-HIV drugs in pregnant women change at different stages of pregnancy and if these changes require dosage adjustments in order to maintain adequate drug levels during pregnancy. Anti-HIV medications are recommended for HIV-infected women during pregnancy not only to treat their infection, but also to reduce the chance of passing the virus to the baby during pregnancy. Changes in the body that occur during pregnancy may affect how the body uses and eliminates these drugs, reducing their levels during pregnancy. Pregnant women 18 years of age or older who are infected with HIV may be eligible for this study. Candidates will have a medical history and physical examination, pregnancy test and blood tests. Participants will come to the NIH Clinical Center once every 6 to 12 weeks until around their 34th week (8 months) of pregnancy and then again at least 1 month after the birth of the baby to have blood drawn. A catheter (thin plastic tube) will be placed in a vein to avoid multiple needle sticks for blood sampling during the day. The first sample will be collected before the patient takes the morning doses of anti-HIV medicines and additional samples will be drawn at 1, 2, 4, 8 and 12 hours after taking the medication. A urine sample will also be collected at each visit.
This multi-center Phase I study is designed to characterize the safety, PK, and PD of TFV/LNG IVR to assess systemic and genital tract bioavailability in healthy women. The IVRs to be used in the study are TFV/LNG IVR (8-10mg per day/20μg per day) or placebo IVR. Samples will be obtained before, during and after 90 days of continuous or interrupted IVR use.
A Study to Learn About the Medicine Called Nirmatrelvir Used in Combination With Ritonavir in People with Weakened Immune Systems or at Increased Risk for Poor Outcomes who are Hospitalized Due to Severe COVID-19
The purpose of this study is to demonstrate the effectiveness of Symtuza® in a rapid reinitiation model of care in patients with HIV-1 infection and who are treatment-experienced but have been off of antiretroviral therapy (ART) for 12 or more weeks.
The study involves delivering one of two interventions - either Promoting Action Towards Health (PATH) or Personalized Cognitive Counseling (PCC) - to 440 men who have sex with men (MSM) who have recently been diagnosed with HIV and assessing whether participants who received PATH achieve greater suppression of HIV viral load, demonstrate greater uptake of care and adherence to treatment, and engage in less sexual HIV transmission risk behavior than participants who received PCC. * PATH consists of two preliminary sessions plus "booster" sessions after 1, 3, and 6 months. * Personalized Cognitive Counseling consists of one session. Participants will complete assessments before participating in their intervention (i.e., at "baseline") and at 3, 6, 9, and 12 month follow-up points. Participants' viral loads will be measured at approximately 6 and 12 months following baseline.
RATIONALE: Giving autologous lymphocytes that have been treated in the laboratory with antibodies may stimulate the immune system to kill tumor cells. Aldesleukin may stimulate the lymphocytes to kill tumor cells. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving laboratory-treated autologous lymphocytes together with aldesleukin and GM-CSF may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of laboratory-treated autologous lymphocytes when given together with aldesleukin and GM-CSF in treating patients with recurrent, refractory, or metastatic advanced solid tumors.
The hypothesis is that participants in the intervention group will experience fewer/less intense side effects from anti-HIV medications, if they receive training sessions on the use of guided imagery, relaxation, and reframing of the medication-taking experience. Such training is not part of the usual care of HIV patients.
The purpose of this study is to compare the efficacy, safety and tolerability of TMC114/r versus Kaletra (a combination pill of lopinavir and ritonavir, ("lpv/rtv") in HIV-1 infected patients who have never been treated with anti-retroviral medications (referred to as "treatment-naïve" patients).
The purpose of this study is to provide early access to TMC114 (a protease inhibitor) for HIV-1 infected patients with limited or no treatment options, who have failed multiple antiretroviral (ARV) regimens, and to evaluate the longer-term safety and tolerability of TMC114/r in combination with other antiretrovirals
The purpose of this study is to determine the effectiveness of the nutritional supplement chromium picolinate in improving insulin resistance, a symptom of diabetes, in HIV-infected patients. The ultimate goal is to find a simple therapy that can prevent the development of diabetes in individuals with HIV.
The purpose of this study is to determine whether HIV and anti-HIV drugs cause mental health problems or make mental health problems worse in children and adolescents who were infected with HIV at birth.
The purpose of this study is to determine the best time to begin anti-HIV treatment in individuals who have HIV and tuberculosis (TB). Study hypothesis: Immediate antiretroviral therapy (ART), initiated after approximately 2 weeks of TB treatment, will reduce the frequency of other AIDS-defining illnesses and death in HIV-infected participants being treated for TB by at least 40% at week 48 when compared to deferred ART, initiated at after 8-12 weeks of TB treatment.
This study will assess the pharmacokinetics, safety, tolerability, maintenance of virological suppression and patient reported outcomes for participants receiving CAB and RPV LA injections following SC administration in the anterior abdominal wall SC tissue compared with IM administration in the gluteus medius muscle in adult participants living with HIV-1 infection in the FLAIR study (NCT02938520).
The First Long-Acting Injectable Regimen (FLAIR) study is being conducted to establish if human immunodeficiency virus type-1 (HIV-1) infected adult participants whose virus is virologically suppressed on an integrase inhibitor single tablet regimen (INI STR) will remain suppressed after switching to a two-drug intramuscular (IM) long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine (RPV). In this study, the INI STR will be limited to abacavir/dolutegravir/lamivudine (ABC/DTG/3TC). FLAIR is a Phase 3, multi-phase, randomized, open label, active-controlled, multicenter, parallel-group, non-inferiority study in HIV-1, anti-retroviral therapy (ART)-naïve adult participants. This study is designed to demonstrate the non-inferior antiviral activity of switching to a two drug CAB LA 400 mg + RPV LA 600 mg regimen every 4 weeks (Q4W: monthly) compared to remaining on ABC/DTG/3TC over 48 weeks (4 weeks oral CAB + RPV, 44 weeks LA therapy). Participants who are HLA-B\*5701 positive at Screening may enroll into the study and receive DTG plus a non-abacavir containing dual nucleoside reverse transcriptase inhibitor (NRTI) regimen. Eligible participants will enroll into the Induction Phase of the study and receive ABC/DTG/3TC for 20 weeks (Week \[-20\] to Day 1). Participants who have an HIV 1 ribose nucleic acid (RNA) \<50 copies per milliliter (c/mL) at Week (-4) will be randomized (1:1) into the Maintenance Phase at Day 1 to either continue ABC/DTG/3TC or to discontinue ABC/DTG/3TC and begin oral therapy with CAB 30 mg + RPV 25 mg once daily for approximately 4 Weeks, followed by monthly CAB LA + RPV LA injections from visit Week 4b until study completion or withdrawal. Participants who successfully complete Week 100 (without meeting study defined withdrawal criteria and who remain virologically suppressed through Week 96: HIV-1 RNA \<50 c/mL) will be given the option to switch to the LA arm in the Extension Phase (using an optional oral lead-in with CAB + RPV) or be withdrawn from the study. Participants will continue to receive injections every 4 weeks during the Extension Phase until CAB LA and RPV LA are either locally approved and commercially available, the participant no longer derives clinical benefit, the participant meets a protocol-defined reason for discontinuation, or until development of either CAB LA or RPV LA is terminated.
The primary objective of this study is to evaluate the efficacy of switching to elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) relative to continuing on a baseline regimen consisting of abacavir/lamivudine (ABC/3TC) plus a 3rd antiretroviral agent in HIV-1 infected participants.
The purpose of this study is to determine if blood levels of the hormonal emergency contraceptive agent, Plan B, are altered by concomitant use with the HIV medication, efavirenz.
The purpose of this study is to evaluate the non-inferiority of ritonavir-boosted GS-9137 relative to a ritonavir-boosted Comparator Protease Inhibitor when used as part of combination antiretroviral regimens in subjects who have failed, or are failing, protease inhibitor therapy.
The purpose of this study is to evaluate the safety, tolerability and efficacy of higher doses of lopinavir/ritonavir, in combination with other anti-HIV medications when administered as either the capsule or liquid formulations, among patients who have not had full viral suppression despite treatment with 3 classes of HIV medications, and at least 2 prior courses of treatment with HIV protease inhibitors. In addition, pharmacokinetics of the active agents, lopinavir and ritonavir will be measured following administration of both the liquid and capsule formulations and compared.
The goal of this study is to examine whether enfuvirtide (T20, Fuzeon) has continued anti-HIV activity in patients experiencing an incomplete virologic response to an enfuvirtide-based regimen.
SCOPE is an observational, prospective study of HIV-1 infected volunteers designed to provide a specimen bank of samples with carefully characterized clinical data. SCOPE specimens will be used to examine multiple questions involving virologic, immunologic, and host factors involved in HIV-1 infection, progression, non-progression, response to treatment, control of HIV-1 virus, and evolution of drug resistance.
The purpose of this study is to see if it is effective to give HIV positive patients recombinant interleukin-2 (rIL-2) in addition to anti-HIV therapy. Patients will be followed over a minimum of 4 years to study the long-term effects of rIL-2 on their HIV disease progression. Anti-HIV therapy has been very successful in treating HIV positive patients and in keeping viral load (level of HIV in the blood) low. However, anti-HIV drugs cannot completely rid the body of the virus, and the immune system is never completely restored in HIV positive patients. Doctors hope that giving patients recombinant interleukin-2 (rIL-2) in addition to their anti-HIV therapy will help improve their immune systems and keep them healthier over a longer period of time. rIL-2 is a hormone naturally produced by the body during an immune response to a microbial infection.
The purpose of this study is to determine whether patients who have asymptomatic HIV infection can discontinue antiretroviral therapy (ART) without adverse clinical, virologic, or immunologic consequences. This study will also assess the virologic, immunologic, and clinical outcomes in any patients who restart ART.
