| OTC | NCT01469234 ↗ | A Study of Onset of Action of Loratadine and Fexofenadine in Participants With Seasonal Allergic Rhinitis (P08712) | Completed | Bayer | Phase 4 | 2011-10-01 | The purpose of this study is to determine the onset of action of two commercially available over-the-counter antihistamines (Loratadine and Fexofenadine) in a model of seasonal allergic rhinitis (SAR). Participants undergo sensitization exposures to Mountain Cedar (juniperus ashei) pollen in a Biogenics Research Chamber; those who demonstrate an adequate allergic response determined by the Major Symptom Complex (MSC) score will then receive drug. |
| New Dosage | NCT02435563 ↗ | Dose Adaptation to Offset the Interaction Between Ticagrelor and Ritonavir by Population-based PK Modeling | Completed | University Hospital, Geneva | Phase 2 | 2014-08-01 | Ticagrelor is a new generation antiplatelet agent with higher efficacy as compared to clopidogrel and prasugrel in treatment of patients with moderate and high ischemic risks. Ticagrelor is active as such and its hepatic metabolism by CYP3A generates also an active metabolite. Because of the remarkable progress in HIV therapies the number of older age patients is on the rise, requiring adequate cardiovascular treatment. Since frontline HIV therapies include ritonavir, a strong inhibitor of CYP3A enzyme, ticagrelor is contraindicated in these patients because of the expected interaction and bleeding risk. A lower efficacy of clopidogrel and prasugrel, which are both pro-drugs, in the presence of ritonavir has been already demonstrated. Therefore, administration of a lower dose of ticagrelor may be a good alternative in HIV patients in order to lessen the impact of this pharmacokinetic interaction. The aim of this study is to adjust the dose of ticagrelor in case of co-treatment with ritonavir to achieve the same pharmacokinetic profile as administered alone using a physiologically-based pharmacokinetic (PBPK) model. As the first step, a pharmacokinetic (PK) model for ticagrelor and its active metabolite will be created based on available in vitro and in vivo parameters in healthy volunteers. An open-label, 2 sessions cross over study will be conducted with 20 healthy male volunteers at Clinical Research Center (CRC) of Geneva University Hospitals (HUG). During the first session of the clinical trial, a single dose 180 mg ticagrelor will be administered to the volunteers and obtained pharmacokinetic data will be fitted into the model for optimization. Thereafter a simulated trial by the Simcyp® simulator in presence of a single dose 100 mg ritonavir will allow evaluating the impact of CYP3A inhibition on the concentration-time profile of ticagrelor and its active metabolite. The necessary dose of ticagrelor to minimize the magnitude of this interaction will be calculated. This new dose will be co-administered with ritonavir in the same volunteers during the second session of the clinical trial. The purpose is to obtain the same PK profile with single dose of 180 mg ticagrelor administered alone and with an adapted dose of ticagrelor co-administered with a single dose 100 mg ritonavir. Moreover, the pharmacodynamic effect of ticagrelor will be measured in both sessions of the clinical trial using two specific platelet function tests: the VAsodilator-Stimulated Phosphoprotein assay (VASP) and VerifyNow® P2Y12. With the same PK profile, the same pharmacodynamic activity is expected. The modulation of activity of CYP3A and P-gp by ritonavir will be also monitored using micro dose midazolam and fexofenadine as probe substrates. The purpose of this study is to use the Simcyp® Simulator mechanistic PBPK modeling to broaden the application field of ticagrelor, especially in HIV patients. Since PK models are often created after clinical observations, the prospective aspect of this study is of particular value as the model will be first created and then applied to an unknown clinical scenario. |
| OTC | NCT03425097 ↗ | Fexofenadine Use in Gastroesophageal Reflux Symptoms | Terminated | Stanford University | Phase 2 | 2018-02-07 | The investigators wish to study the effectiveness of Fexofenadine (an over the counter allergy pill) for the treatment of gastroesophageal reflux symptoms in patients who still have symptoms despite being on a proton pump inhibitor. The investigators will do this by giving participants both Fexofenadine (an H1 blocker) for 2 weeks and placebo (sugar pill) for 2 weeks. The participants will not know which drug they are getting at a particular time. This will help the investigators better assess the true effectiveness of Fexofenadine. |

| NCT00029692 ↗ | Effects of Ginseng and Ginkgo on Drug Disposition in Man | Completed | National Center for Complementary and Integrative Health (NCCIH) | Phase 2 | 2002-03-01 | This study will assess the effects of ginseng and ginkgo on 1) cognitive function, 2) enzymes that process drugs, and 3) enzymes that may help prevent cancer. |
| NCT00044811 ↗ | Efficacy and Safety of Fexofenadine in Mild to Moderate Persistent Asthma | Completed | Sanofi | Phase 3 | 2002-03-01 | The purpose of this study is to investigate the efficacy and safety of fexofenadine 120mg BID compared to placebo in the treatment of subjects with mild to moderate persistent asthma |
| NCT00044824 ↗ | Efficacy and Safety of Fexofenadine in Mild to Moderate Persistent Asthma | Completed | Sanofi | Phase 3 | 2002-02-01 | The purpose of this study is to investigate the efficacy and safety of fexofenadine 120mg BID compared to placebo in the treatment of subjects with mild to moderate persistent asthma |
| NCT00045955 ↗ | Long-Term Safety Performance of Fexofenadine in Asthma | Completed | Sanofi | Phase 3 | 2002-02-01 | The purpose of this study is to assess the long-term safety performance of fexofenadine compared to montelukast in subjects with asthma |
| NCT00103012 ↗ | Drug Interactions of Echinacea, Ginseng, and Ginkgo Biloba Taken With Lopinavir/Ritonavir in Healthy Volunteers | Completed | National Institutes of Health Clinical Center (CC) | Phase 4 | 2005-01-01 | This study will examine the interaction of the HIV combination medication lopinavir/ritonavir with the herbal products echinacea, ginseng, and ginkgo biloba. Patients with HIV infection often take herbal products and dietary supplements in addition to their doctor-prescribed medicines to treat the disease, lessen the side effects of anti-viral drugs, and improve their overall well being. Alternative medicines such as these may, however, interfere with the elimination of lopinavir/ritonavir from the body, causing either higher or lower blood levels of these drugs than would be expected. This study will assess in healthy subjects any potential harms of taking echinacea, ginseng, or ginkgo biloba together with lopinavir/ritonavir. Healthy normal volunteers between 18 and 50 years of age may be eligible for this study. Candidates are screened with a history, physical examination, and blood tests, including an HIV test and a pregnancy test for women. Pregnant women are excluded from the study. Participants come to the NIH Clinical Center after fasting overnight for the following procedures: Visits 1 and 2: A catheter (plastic tube) is placed in an arm vein to collect blood samples. After the first sample is drawn, the subject takes 8 mg of midazolam syrup and two fexofenadine tablets. Midazolam is a sedative, and fexofenadine (Allegra) is a medicine used to treat allergies. Subjects are given breakfast an hour after taking the drugs. Blood samples are collected at 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8 and 24 hours after taking the drugs to measure blood levels of fexofenadine. An extra sample is collected at the 4-hour mark to measure the midazolam level. The catheter is removed after the 8-hour blood draw and subjects are dismissed home. They return the following morning (visit 2) for the 24-hour blood draw. Visit 3: From 7 to 28 days after visit 1, subjects begin taking lopinavir/ritonavir capsules twice a day by mouth for a total of 29.5 days. On day 15 they return to the clinic for lopinavir/ritonavir blood levels as were done for fexofenadine, except that samples are collected once before breakfast and then at 0.5, 1, 2, 3, 4, 6, 8 and 12 hours after the lopinavir/ritonavir dose. An extra sample is collected for routine tests. The catheter is removed after the 12-hour draw and the subject is dismissed home. The next morning, subjects begin taking one of the following: echinacea 500 mg 3 times a day; ginkgo biloba 120 mg twice a day; or ginseng 500 mg 3 times a day for 28 days. Visit 4: On the last day of taking lopinavir/ritonavir, subjects return to the clinic again for blood level measurements of these drugs as on visit 3, except that the catheter is removed and the subject dismissed home after the 8-hour blood draw. Visits 5 and 6: On the last day of taking the herbal supplement, subjects return to the clinic for repeat measurement of fexofenadine and midazolam levels, as described in visits 1 and 2. At the final visit (visit 6) an additional blood sample is collected for repeat laboratory testing. ... |
