CID 0821 - Pilot Study to Evaluate HIV Viremia and Persistence in Acutely HIV-Infected Antiretroviral Naïve Patients Treated With Darunavir/Ritonavir and Etravirine

Purpose: This is a pilot study to evaluate HIV viremia and persistence in acutely HIV infected antiretroviral naïve patients treated with Darunavir/ritonavir and Etravirine

Participants: 20 participants, age 18 and older, HIV infected, antiretroviral naïve patients

Procedures (methods): ARV treatment with Darunavir/ritonavir and Etravirine,

Optional studies:

Genital secretion samples, Cerebrospinal fluid samples, Leukapheresis, Endoscopy/colonoscopy

Visão geral do estudo

Descrição detalhada

Study Design

This is a multicenter, single arm, 48-week open-label pilot study of DRV/R & ETR in acute HIV infection. Study sites will be members of the Duke-UNC Acute HIV Infection Study Consortium. If baseline resistance is detected after treatment begins (e.g. evidence of pre-existing baseline resistance (genotypic or phenotypic) that may adversely affect the efficacy of the study regimen), the patient may elect to alter treatment as per best clinical practice. The new regimen will not be provided by the study, but will be obtained for the participant through available clinical resources.

After patients are identified with acute HIV infection, they will be offered the opportunity to participate in the study. Patients will also be offered the opportunity to co-enroll in CHAVI 001 and 012, studies that follow the virological and immunological response of patients with AHI, regardless of the initiation of ART. An overall consent form will be signed for study participation, and separate informed consents with signatures will be obtained for optional studies. Patients will be eligible for participation after signing the overall consent - agreeing to participate in studies of other compartment specimens is not required for enrollment. At the initial visit, patient eligibility will be confirmed with appropriate laboratory testing (see "STUDY POPULATION"). When eligibility is verified, entry laboratory studies will be obtained, and the participants will be started on DRV/r, and ETR. All participants will be followed at regular intervals thereafter as specified in the schedule of evaluations. Participants meeting criteria for virologic failure will be offered the opportunity to switch to the best available regimen as selected by their HIV provider.

Hypothesis

Combination therapy with DRV/R & ETR will suppress plasma viremia and improve immunologic function in antiretroviral (ART)-naïve, acutely HIV-infected (AHI) patients, and will limit replication in HIV-1 cellular compartments.

  4. Screening HIV-1 RNA >1,000 copies/mL obtained within 30 days at study entry.
  5. Lab values obtained within 30 days prior to study entry:
  6. Absolute neutrophil count >500/mm3
  7. Hemoglobin > 8.5 g/dL for men and > 8.0 g/dL for women

  10. ALT (SGPT) ≤2.5 x ULN
  11. Total bilirubin <2.5 x ULN
  12. Calculated creatinine clearance (Cockcroft-Gault formula) > 30mL/min:

    • CrCl = (140-age) x body weight (kg) (x 0.85 if female)
    • Serum creatinine [mg/dL] x (72)
  13. For women of reproductive potential, a negative serum or urine pregnancy test within 7 days prior to initiating antiretroviral study medications. Reproductive potential is defined as females who have reached menarche and have not been post-menopausal for at least 24 consecutive months, or have not undergone surgical sterilization (e.g., hysterectomy, bilateral oophorectomy, or salpingotomy). Acceptable documentation of surgical sterilization includes patient-reported history.
  14. If participating in sexual activity that could lead to pregnancy, female study patients must use at least one form of contraception, which could consist only of a barrier method. All patients must continue to use contraception for 6 weeks after stopping the study medications. Acceptable methods of contraception include: condoms (male or female) with or without spermicidal agent, diaphragm or cervical cap with spermicide, or IUD. Female volunteers not of reproductive potential are not required to use contraception.
  15. Ability and willingness of patient to give written informed consent.

Exclusion Criteria:

  1. Women who are pregnant or breast-feeding.
  2. Women with a positive pregnancy test on enrollment or prior to study drug administration.
  3. Women of reproductive potential who are unwilling or unable to use acceptable methods to avoid pregnancy for the entire study period
  4. Use of immunomodulators (e.g., interleukins, interferons, cyclosporine), HIV vaccine, systemic cytotoxic chemotherapy, or investigational therapy within 30 days prior to study entry.

    • Prednisone at a daily dose of 10 mg or less (physiologic replacement dose) is permitted.
  5. Known allergy/sensitivity to study drugs or their formulations.
  6. Difficulty swallowing capsules/tablets.

  12.

An overall summary score was created by averaging all tests. Participants also completed the self-reported functional status Patient's Assessment of Own Functioning Inventory (PAOFI) and the Activities of Daily Living Scale (ADLS). Best available demographically corrected normative data were utilized to create z scores. A negative z score denotes below-average performance relative to a US normative comparison population. A higher z score is a better outcome.
