E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To identify an optimal dose combination(s) of tipranavir (TPV) and ritonavir (RTV) for antiretroviral treatment naive HIV-1 positive patients that can be used in pivotal trial by assessing the steady-state pharmacokinetics and short-term efficacy and safety. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study will be evaluated by the following end-points: TPV pharmacokinetics -Apparent oral clearance (CL/F) -Volume of distribution (V/F) -Terminal half-life (t1/2) -Tmax RTV pharmacokinetics -AUC(0-24h) for QD dosing, AUC(0-12h) for BID dosing -C(pre24h) for QD dosing, C(pre12h) for BID dosing -C(prelast) and T(last) -Cmax and Tmax -Apparent oral clearance (CL/F) -Volume of distribution (V/F) -Terminal half-life (t1/2) Safety and tolerability -Clinical laboratory results (hematology and clinical chemistry) -Adverse events -Physical examination |

E.3 | Principal inclusion criteria |
Signed informed consent in accordance with GCP and local regulatory requirements prior to trial participation. HIV-1 infected men and non-pregnant women who are treatment naïve, with positive serology (EIA) confirmed by Western blot. Age >=18 and <=65 years. CD4 > 200 cells/mm**3 Viral load (HIV-1 mRNA viral load) > 5,000 copies/mL. Ability to swallow multiple large capsules without difficulty. Acceptable laboratory values that indicate adequate baseline organ function at screening visit. Laboratory values are considered to be acceptable if the severity of any parameter is <= Grade 2, based on the DAIDS/ACTG Grading Scale Acceptable medical history, physical examination, and 12-lead ECG at screening Willingness to abstain from the following starting 2 weeks prior to administration of any study medication and up until the end of the study: -Grapefruit or grapefruit juice, Seville oranges, St. Johns Wort, and Milk Thistle. Willingness to abstain from alcohol 3 days prior to administration of any study medication up to the end of the study. Willingness to abstain from the following starting 3 days prior to PK sampling: -Garlic supplements and methylxanthine containing foods or drinks (including coffee, tea, cola, energy drinks, chocolate, etc.). Willingness to abstain from over-the-counter herbal medications for the duration of the study. Willingness to abstain from any over the counter medication 7 days prior to administration of any study medication (including vitamins, minerals, dietary supplements and antacids) during the study until completion of the post study assessments. |

E.4 | Principal exclusion criteria |
Female patients of reproductive potential who: -have positive serum pregnancy test. -have not been using a barrier method of contraception for at least 3 months prior to participation in the study. -are not willing to use a reliable method of barrier contraception (such as diaphragm with spermicidal cream/jelly or condoms with spermicidal foam), during and 60 days after completion/termination of the trial. -are breast-feeding. Suspected or documented seroconversion within last 6 months Participation in another trial with an investigational medicine within 2 months prior to Day 0 of this study. Use of any pharmacological contraceptive (including oral, patch or injectable contraceptives) within 1 month prior to Day 0 and for the duration of the study. Use of hormone replacement therapy within 1 month prior to Day 0 and anytime during the study. History of acute illness within 30 days prior to Day 0. Have evidence of active or acute HBV or HCV. Alcohol or substance abuse within 1 year prior to screening or during the study. Patients with a history of any illness or allergy that, in the opinion of the investigator, might confound the results of the study or pose additional risk in administering TPV. Patients who have taken (within 7 days prior to Day 0) any over-the-counter or prescription medication that, in the opinion of the investigator in consultation with the BI clinical monitor, might interfere with absorption, distribution, or metabolism of the study medications. Known hypersensitivity to any ingredients of the test drug. Inability to adhere to the protocol. Genotypic resistance to tipranavir (defined as a TPV mutation score > 4). |
