NCT01761643

Brief Summary

CCTG 595 is a controlled, open-label, two-arm, randomized (1:1) clinical demonstration project to determine if the use of a text-message based adherence intervention (iTAB) improves retention and adherence to PrEP compared to standard of care (SoC) PrEP delivery.

Outcome Measures

Primary Outcomes (1)

  • Adherence to PrEP

    Proportion of participants adherent to PrEP as measured by TFV-DP dried blood spot (DBS) concentrations \> 719 fmol/punch at Week 12 and the last on-drug visit.

    Baseline to Week 48

Secondary Outcomes (2)

  • Perfect Adherence to PrEP

    Baseline to Week 48

  • Rate of HIV Seroconversion

    Up to 2.5 years after baseline

Study Arms (2)

Standard of Care (SoC)

NO INTERVENTION

This proposal will perform a study of potential methods to improve adherence and retention by evaluating standard procedures versus the use of the iTAB platform. All subjects will receive SoC that will include health education, clinical assessments, laboratory safety monitoring, STI and HIV screening, HIV risk reduction counseling, assessment of psycho-social barriers, adherence counseling, and completion of a computer based survey.

SoC + iTab

ACTIVE COMPARATOR

Subjects assigned to the iTAB intervention will receive daily dosing reminders that will be sent for the first 6 weeks and then continue with reminders for the duration of the study. Subjects will have visits with the study coordinator to introduce the iTAB texting system. Once the time is identified, the text reminder system is automated. Patients will confirm medication taking via text responses to the personalized reminders. If a participant does not respond on three consecutive occasions, a high alert message (chosen by the participant) will be sent. If the subject does not respond to this message, the study coordinator would initiate phone calls to contact the subject and explore barriers.

Device: SoC + iTab

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Man or transgender M to F who has sex with men.
  • Age 18 years or older.
  • Subjects must have substantial ongoing risk of acquisition of HIV as evident by one or more of the following:
  • Has at least one HIV infected sexual partner for ≥4 weeks.
  • No condom use during anal intercourse with ≥3 male sex partners who are HIV-positive or of unknown HIV status during the last 3 months.
  • No condom use during anal sex with ≥1 male partner and STI diagnosis during the last 3 months.
  • Negative for HIV infection by rapid HIV test and confirmed negative by NAT or other sensitive method such as antibody- antigen test.
  • Acceptable laboratory values in the past 30 days:
  • Calculated creatinine clearance of at least 60 mL/min by the Cockcroft-Gault formula (eCcr (male) in mL/min = \[(140 - age in years) x (lean body weight in kg)\] / (72 x serum creatinine in mg/dL)
  • Alanine aminotransferase (ALT) and/ or aspartate aminotransferase (AST) \< 3 x upper limit of normal (ULN)
  • Hemoglobin \> 9 g/dL
  • Absolute neutrophil count \> 750/ mm3
  • Platelets \> 75,000/ mm3

You may not qualify if:

  • Unable to give informed consent.
  • Active hepatitis B (positive hepatitis B surface antigen (HBSAg) or HBSAg negative/ HB core antibody positive/ HBV PCR positive).
  • Has substantial medical condition, that in the opinion of the investigator would preclude participation, as defined by
  • cardiovascular condition that may lead to an increased risk of complication if placed on study drugs.
  • gastrointestinal condition that would impair absorption of study drugs.
  • neurological or psychiatric condition that would significantly impair the ability to adhere to PrEP.
  • calculated GFR \< 60 mL/min.
  • alcohol or drug abuse or dependence that would significantly impair the ability to adhere to PrEP (only for those with severe impairment).
  • other medical condition that would unacceptably increase the risk of harm from study drug or significantly impair the ability to adhere to PrEP.
  • Suspected sensitivity or allergy to the study drug or any of its components.
  • Currently using an essential product or medication that interacts with the study drug such as the following:
  • ART (including nucleoside analogs, non-nucleoside reverse transcriptase inhibitors, protease inhibitors or investigational antiretroviral agents)
  • Agents with known nephrotoxic potential:
  • aminoglycoside antibiotics (including gentamicin)
  • IV amphotericin B
  • +18 more criteria
