NCT02251223

Brief Summary

Primary: Sequentially determine the effects of three dose combinations of tipranavir (TPV) / ritonavir (RTV) (administered b.i.d.), TPV 1250 mg/RTV 100 mg vs. TPV 750 mg/RTV 100 mg vs. TPV 250 mg/RTV 200 mg on the steady-state pharmacokinetics of zidovudine, lamivudine, stavudine, didanosine, abacavir, nevirapine and efavirenz at approved doses. The three treatment groups will be enrolled sequentially starting with the highest tipranavir dosage group first and ending with the lowest tipranavir dosage group. Secondary: A) To assess the effects of zidovudine, lamivudine, stavudine, didanosine, abacavir, nevirapine, and efavirenz on the pharmacokinetics of tipranavir/ritonavir compared to historical controls. B) To assess the safety of three tipranavir/ritonavir combinations when used in combination with protocol defined antiretrovirals.

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Signed informed consent prior to trial participation
  • Between 18 and 75 years of age inclusive
  • Female subjects of child bearing potential are required to use a barrier contraceptive method for at least 12 weeks prior to administration of study medication, during study medication administration, and for 28 days after the end of the study
  • Ability to swallow capsules without difficulty
  • A Body Mass Index (BMI) between 11 and 50 kg/m2
  • Reasonable probability for completion of the study
  • Acceptable screening laboratory values. All laboratory values ≤ Grade I (e.g., creatine phosphokinase (CPK), amylase, triglycerides) are permissible if documentation of stability for 2 months or more is available. Abnormalities \> Grade I are subject to approval by BI clinical monitor or designee
  • Acceptable medical history, physical examination, ECG, and chest X-ray prior to entering the treatment phase of the study
  • Willingness to abstain from alcohol from Day -2 to Day 23
  • Willingness to abstain from ingesting grapefruit, grapefruit juice, Seville oranges or orange marmalade from Day -2 to Day 23
  • Negative urine drug screen for drugs of abuse. Subjects on methadone or equivalent narcotic maintenance programs will be permitted to enter the study
  • Documented HIV-1 RNA load (by PCR) at screening of ≤20,000 copies/mL for at least twelve weeks. Acceptable documentation would include laboratory data, a letter or a verbal report from another provider noted in the subject records.
  • Stable doses of approved NRTIs and NNRTIs 2 for a minimum of twelve weeks prior to study Day 0. Subjects on efavirenz must be able to tolerate daily morning (8:00 a.m.) dosing starting at screening period and for 22 days of the study. Subjects receiving bid ddI must be willing to accept a change to the once a day delayed release (EC) formulation

You may not qualify if:

  • Female subjects who:
  • have a positive serum pregnancy test at Screening Period Day -14 to -7
  • are breast feeding
  • Receipt of any other investigational medicine for 30 days prior to Day 0
  • Receipt of any known cytochrome P450 3A4 (CYP3A4) altering drug i.e. phenothiazines, cimetidine, barbiturates, ketoconazole, fluconazole, rifampin, steroids and herbal medications for 30 days prior to Day 0. No antibiotics permitted within 10 days prior to Day 0
  • Ingestion of grapefruit, grapefruit juice, Seville oranges or orange marmalade within 2 days of study entry (Day 0)
  • Blood or plasma donations (\>100 ml total) for research or altruistic reasons within 30 days prior to Day 0
  • Seated systolic blood pressure either \<100 mm Hg or \>150 mm Hg; resting heart rate either \<50 beats/minute or \>90 beats/minute
  • History of any illness, including malabsorption, irregular food intake or gastrointestinal intolerance, or allergy that, in the opinion of the investigator, might confound the results of the study or pose additional risk in administering TPV/RTV
  • Any acute illness within 2 weeks prior to Day 0
  • Subjects who are currently taking any over-the-counter drug within 7 days prior to Day 0, or who are currently taking any prescription drug that, in the opinion of the investigator (in consultation with the BI medical monitor and/or pharmacokineticist), might interfere with either the absorption, distribution or metabolism of the TPV/RTV
  • Hypersensitivity to TPV, RTV or sulfonamide containing drugs
  • Using the adherence diary, subject has less than 100% documented adherence for the last 14 doses (7 days) of baseline antiretroviral medications prior to Day 0. Subjects has less than 100% adherence for the last 7 doses (7 days) of efavirenz and ddI (delayed release) prior to Day 0
