E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of this study is to identify an optimal dose combination(s) of tipranavir (TPV) and ritonavir (RTV) for antiretroviral treatment naïve HIV-1 infected patients that can be used in pivotal trial by assessing the steady-state pharmacokinetics and short-term efficacy and safety PRIMARY ENDPOINT(S)
The primary endpoints include: • TPV pharmacokinetics o AUC0-24h for QD dosing, AUC0-12h for BID dosing o Cp24h for QD dosing, Cp12h for BID dosing o Cmin o Cmax
• Efficacy o Change from baseline in HIV-RNA viral load (log10)
|
|
E.2.2 | Secondary objectives of the trial |
SECONDARY ENDPOINT(S) • TPV pharmacokinetics o Apparent oral clearance (CL/F) o Volume of distribution (V/F) o Terminal half-life (t1/2) o Tmax
• RTV pharmacokinetics o AUC0-24h for QD dosing, AUC0-12h for BID dosing o Cp24h for QD dosing, Cp12h for BID dosing o Cplast and Tlast o Cmax and Tmax o Apparent oral clearance (CL/F) o Volume of distribution (V/F) o Terminal half-life (t1/2)
• Safety and tolerability o Clinical laboratory results (hematology and clinical chemistry) o Adverse events o Physical examination

E.3 | Principal inclusion criteria |
3.3.1 Inclusion criteria Patients meeting the following criteria will be eligible for participation in this study: • 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/mm3 • 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 (see Appendix 10.2). • 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: o Grapefruit or grapefruit juice, Seville oranges, St. John’s 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: o 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 |
Exclusion criteria Patients with any of the following criteria are excluded from participation in this trial: • Female patients of reproductive potential who: o Have positive serum pregnancy test. o Have not been using a barrier method of contraception for at least 3 months prior to participation in the study. o 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. o 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).
