Tipranavir Dose-response Study Using a Prototype Self-emulsifying Drug Delivery System (SEDDS) Formulation in Treatment-naive HIV-1 Infected Patients Report on the Post-study Option, a Treatment of Triple Therapy With Delavirdine, ZDV and 3TC Without Tipranavir

Tipranavir (PNU-140690): A Fourteen Day Dose-response Study Using a Prototype Self-emulsifying Drug Delivery System (SEDDS) Formulation in Treatment-naive HIV-1 Infected Patients. Report on the Post-study Option, a 46-week Treatment Period of Triple Therapy With Delavirdine, ZDV and 3TC Without Tipranavir

To investigate the safety of a standard triple therapy regimen of delavirdine (DLV), zidovudine (ZDV), and lamivudine (3TC) following 14 days of experimental treatment with regimens of tipranavir (TPV) with and without ritonavir (RTV)

Exclusion Criteria:

• Previous treatment with any antiretroviral drugs for more than 2 weeks
• Clinically significant, active and/or acute (onset within the prior month) medical problems including opportunistic infections, such as active cryptococcosis, Pneumocystis carinii pneumonia (PCP), herpes zoster, histoplasmosis or cytomegalovirus (CMV) , or non-opportunistic diseases including, but not limited to, progressive multifocal leukoencephalopathy, lymphoma, or malignancy requiring systemic therapy
• History of clinically significant nervous system or muscle diseases, seizure disorder, or psychiatric disorder that might impair compliance with the study
• Receipt of any known enzyme-inducing drugs including rifabutin, rifampin, carbamazepine, dexamethasone, phenobarbital, phenytoin, sulfamidine, sulfinpyrazone, or troleandomycin within 30 days prior to participation in the study
• Receipt of any investigational medication within 30 days prior to participation in the study
• Receipt of oral contraceptives within 30 days prior to participation in the study
• Pregnancy or lactation (serum ß-human chorionic gonadotropin (ß-HCG) test negative at second screen visit of the tipranavir phase of trial)
