Detailed Description
Study SGN113399 is a Phase 2b randomized, partially-blinded, multicenter, parallel-group, dose-ranging study to be conducted in HIV-1 infected ART-experienced adults with documented NNRTI resistance. ...
Eligibility Criteria
Inclusion
- HIV-1 infected adults greater than or equal to 18 years of age. Females are eligible to enter and participate in the study if she is (1) non-childbearing potential, (2) child bearing potential with negative pregnancy test at screening and Day 1 and agrees to use protocol-specified methods of birth control while on study.
- HIV-1 infection with a screening plasma HIV-1 RNA greater than or equal to 400copies/mL
- Previously received or current treatment with antiretroviral therapy (HAART) for HIV-1 infection (patient may be off ART at time of screening)
- HIV-1 harboring NNRTI resistance by screening genotype (defined as the presence of at least 1 NNRTI resistance-associated mutations)
Exclusion
- Any pre-existing physical or mental condition (including substance abuse disorder) which, in the opinion of the Investigator, may interfere with the subject's ability to comply with the dosing schedule and/or protocol evaluations or which may compromise the safety of the subject
- Any condition which, in the opinion of the Investigator, may interfere with the absorption, distribution, metabolism or excretion of the drug or render the subject unable to take oral medication
- Women who are currently breastfeeding
- Any evidence of an active Centers for Disease and Prevention Control (CDC) Category C disease \[CDC, 1993\], except cutaneous Kaposi's sarcoma not requiring systemic therapy
- History of ongoing or clinically relevant hepatitis within the previous 6 months, including chronic hepatitis B virus (HBV) infection (HBsAg positive). Asymptomatic individuals with chronic hepatitis C virus (HCV) infection will not be excluded, however Investigators must carefully assess if therapy specific for HCV infection is required; subjects who are anticipated to require such therapy during the randomized portion of the study must be excluded
- History of liver cirrhosis with or without hepatitis viral co-infection
- Ongoing or clinically relevant pancreatitis
- History of the following cardiac diseases: myocardial infarction, congestive heart failure, documented hypertrophic cardiomyopathy, sustained ventricular tachycardia
- Personal or known family history of prolonged QT syndrome
- History or presence of allergy or intolerance to the study drugs or their components, or a history of drug or other allergy that, in the opinion of the Principal Investigator, contraindicates their participation. In addition, if heparin is used during PK sampling, subjects with a history of sensitivity to heparin or heparin-induced thrombocytopenia should not be enrolled
- HIV-1 genotype results with any of the following will be excluded: (1)Any screening genotype with virus showing a Y181 mutation in combination with any other NNRTI resistance-associated mutations, (2) Any screening genotype with virus showing a Y181I or Y188L alone or in combination with any other NNRTI resistance-associated mutations
- HIV-1 phenotype results with any of the following will be excluded: (1) Any screening phenotype with virus showing etravirine fold change \>10, (2) Any screening phenotype with virus showing darunavir fold change \> 20, (3) Any screening phenotype with virus showing raltegravir fold change \>1.5
- Any acute laboratory abnormality at screening, which, in the opinion of the Investigator, would preclude the subject's participation in the study of an investigational compound. Any verified Grade 4 laboratory abnormality at screening would exclude a subject from study participation unless the Investigator can provide a compelling explanation for the laboratory result(s) and has the assent of the medical monitor
- Any of the following laboratory values at screening: (1) Creatinine clearance \<50 mL/min via Cockroft-Gault method, (2) Alanine aminotransferase (ALT) greater than or equal to 5 times ULN. Subjects with ALT \>2xULN but \<5xULN may participate in the study, if in the opinion of the Investigator and GSK medical monitor the lab abnormality will not interfere with the study procedures or compromise subject safety, (3) Alanine aminotransferase (ALT) greater than or equal to 3xULN and bilirubin greater than or equal to 1.5xULN (with \>35% direct bilirubin
- Any clinically significant finding on screening electrocardiograph (ECG), specifically (a single repeat is allowed to determine eligibility): (1) Heart rate \<45 and \>100bpm (males), \<50 and \>100bpm (females); Note: A heart rate from 100 to 110 BPM can be rechecked within 30 minutes to verify eligibility, (2) QRS duration \>120msec, (3) QTc interval \>450msec, (4) Non-sustained (greater than or equal to 3 consecutive beats) or sustained ventricular tachycardia, (5) Sinus pauses \>2.5 seconds, (6) 2nd degree (Type II) or higher AV (Atrioventricular) block, (7) Evidence of WPW (Wolff-Parkinson-White) syndrome (ventricular preexcitation), (8) Pathologic Q waves (defined as Q wave \>40msec OR depth \>0.4 mV, (9) Any other abnormality which in the opinion of the investigator would interfere with the safety of the subject
- Treatment with any of the following agents within 28 days prior to screening, or has an anticipated need for these agents during the study: (1) radiation therapy or cytotoxic chemotherapeutic agents, (2) immunomodulators (such as systemic corticosteroids, interleukins, or interferons); Note: Subjects using short-term (\<7 day) steroid tapers and inhaled corticosteroids are eligible for enrollment, (3) Any non-protocol-specified agent with documented activity against HIV-1 in vitro
- Treatment with an HIV-1 immunotherapeutic vaccine within 90 days prior to screening
- Receipt of an experimental drug and/or vaccine within 28 days or 5 half-lives, or twice the duration of the biological effect of the experimental drug or vaccine, whichever is longer, prior to screening
- Immunization within 28 days prior to first dose of IP
