About this study

Official title: Steady State Pharmacokinetics (PK) of Fosamprenavir (FPV) Alone or in Combination With Low Dose Ritonavir (/r) (1400mg BID, 1400mg/100mg QD or 700/100mg BID) and the Chemokine Receptor 5 (CCR5) Entry Inhibitor Maraviroc (MVC) 300mg BID in Healthy Volunteers

To date, no study has investigated whether there is a drug interaction between the protease inhibitor fosamprenavir and the entry inhibitor maraviroc. COL112237 is a randomized, open-label, 6-arm, 3-period, drug interaction study to assess steady-state plasma amprenavir (APV) and maraviroc (MVC) pharmacokinetics in 48 healthy, HIV-negative adults after administration of a 7-day regimen of MVC 300mg BID alone and after 14-day regimens of unboosted fosamprenavir (FPV) 1400mg twice daily (BID), FPV 700mg/RTV 100mg BID, or FPV 1400mg/ritonavir (RTV) 100mg once daily (QD) with and without concurrent MVC 300mg BID. Blood samples for drug concentration measurement will be collected over 12 hours at the end of each dosing period. Subjects will undergo a physical examination, complete blood count (CBC) with differential, HIV test, hepatitis B/C test, liver function test, renal function analysis, and lipid panel at screening, and all of these tests, except those for HIV and hepatitis B/C, will be repeated at follow-up post-study. Adverse events and adherence (by pill count and medication diary) will be assessed by the investigator/study personnel at the end of each dosing period.

Read the detailed description

This randomized, open-label, six-arm, three-period drug interaction study will recruit 48 healthy volunteers so as to obtain a minimum of 36 evaluable subjects at a single study center in the U.S. The study will have a screening visit, 3 treatment visits for PK sampling and a follow-up visit. The screening visit will be conducted within 30 days prior to receiving the first dose. Subjects will then be randomized into 1 of 6 treatment groups as shown below:

Cohort Size Period 1 Days 1 to 7 Period 2 Days 1-14 Period 3 Days 1-14

A 8 MVC 300mg BID; FPV 1400mg BID; FPV 1400mg BID \& MVC 300mg BID

B 8 MVC 300mg BID; FPV 1400mg BID \& MVC 300mg BID; FPV 1400mg BID

C 8 MVC 300mg BID; FPV 700mg BID \& RTV 100mg BID; FPV 700mg BID \& RTV 100mg BID \&MVC 300mg BID

D 8 MVC 300mg BID; FPV 700mg BID \& RTV 100mg BID \& MVC 300mg BID; FPV 700mg BID \& RTV 100mg BID

E 8 MVC 300mg BID; FPV 1400mg QD \& RTV 100mg QD; FPV 1400mg QD \& RTV 100mg QD \& MVC 300mg BID

F 8 MVC 300mg BID; FPV 1400mg QD \& RTV 100mg QD \& MVC 300mg BID; FPV 1400mg QD \& RTV 100mg QD

Study subjects will enter the clinic in the morning prior to dosing and remain at the center for 12 hours following each dose. Fourteen to 21 days following completion of the third dosing period, study subjects will return to the clinic for follow-up assessment. The total duration of the study will be approximately 86 days from screening through follow up. Blood samples for drug concentration measurement of amprenavir (APV) and maraviroc(MVC) concentrations will be collected over 12 hours at the end of each dosing period (at 0 [baseline], 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 12 hours post-dose). Subjects will undergo a physical examination, CBC with differential, HIV test, hepatitis B/C test, liver function test, renal function analysis, and lipid panel at screening, and all of these tests except those for HIV and hepatitis B/C will be repeated at follow-up post-study. Adverse events and adherence (by pill count and medication diary) will be assessed by the investigator/study personnel at the end of each dosing period. Evaluable patients will be required to have adhered to at least 95% of their study drug doses. Plasma APV and MVC concentrations will be analyzed using a validated high-performance liquid chromatography method with tandem mass spectrometric detection (HPLC/MS/MS). Plasma APV and MVC pharmacokinetic parameters measured will include maximum concentration (Cmax), time to maximum concentration (Tmax), minimum concentration (Cmin), and area under the concentration-time curve (AUC). All these parameters, except Tmax, will be log-transformed before statistical analysis. Analysis of variance, considering treatment as a fixed effect and subject as a random effect will be performed using Statistical Analysis Software (SAS), and assuming a treatment ratio for steady-state APV PK parameters as 1.0, the 90% confidence intervals will be within the range 0.81-1.24.

Measured: Day 14 of the FPV 1400mg BID, FPV 1400mg/MVC 300mg BID, FPV 700mg/RTV 100mg BID, FPV 700mg/RTV 100mg/MVC 300mg BID, FPV 1400mg/RTV 100mg QD, and FPV 1400mg/RTV 100mg QD plus MVC 300mg BID regimens
AUC: Steady-state Plasma Amprenavir (APV) Pharmacokinetics ( PK) Following Admin of Fosamprenavir (FPV) 1400mg BID, FPV 700mg/Ritonavir (RTV) 100 mg BID, or FPV 1400mg/RTV 100mg QD With and Without Concurrent (Maraviroc) MVC 300mg BID.
Amprenavir (APV) is the active ingredient/metabolite of Fosamprenavir (FPV).
Measured: Day 14 of the FPV 1400mg BID, FPV 1400mg/MVC 300mg BID, FPV 700mg/RTV 100mg BID, FPV 700mg/RTV 100mg/MVC 300mg BID, FPV 1400mg/RTV 100mg QD, and FPV 1400mg/RTV 100mg QD plus MVC 300mg BID regimens
Cmin/Cmax: Steady-state Plasma MVC PK Following Administration of RTV
Amprenavir (APV) is the active ingredient/ metabolite of Fosamprenavir (FPV). MVC minimum concentration (Cmin), maximum concentration (Cmax), and area under the plasma concentration-time curve (AUC), as determined from MVC concentrations observed in blood samples obtained at baseline, and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 12 hours during the period when MVC 300mg BID was administered with the FPV-Containing BID regimens (FPV 1400mg BID, FPV 700mg/RTV 100 mg BID), and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours during the period when MVC 300mg BID was administered with the FPV QD regimen (FPV 1400mg/RTV 100mg QD).

Secondary outcomes (1)

Number of Participants Who Experienced an Adverse Event
Safety/tolerability data collected included all adverse events (AEs) reported within the time frame of each regimen evaluated. The intent was to compare adverse events for each sequence and not for each regimen. The regimens for which AE information was culled were:
- MVC 300mg BID alone
- FPV 1400mg BID alone
- FPV 700mg/RTV 100 mg BID alone
- FPV 1400mg/RTV 100mg QD alone
- FPV 1400mg BID combined with MVC 300mg BID
- FPV 700mg/RTV 100 mg BID combined with MVC 300mg BID
- FPV 1400mg/RTV 100mg QD combined with MVC 300mg BID The severity of reported AEs was graded according to DAIDS criteria, Version 1.0 (National Institute of Allergy and Infectious Diseases (NIAID). Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 1.0. Division of Acquired Immunodeficiency Syndrome (DAIDS), Washington D.C.; 2004

MVC minimum concentration (Cmin), maximum concentration (Cmax), and area under the plasma concentration-time curve (AUC), as determined from MVC concentrations observed in blood samples obtained at baseline, and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 12 hours during the period when MVC 300mg BID was administered with the FPV-Containing BID regimens (FPV 1400mg BID, FPV 700mg/RTV 100 mg BID), and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, and 24 hours during the period when MVC 300mg BID was administered with the FPV QD regimen (FPV 1400mg/RTV 100mg QD). As Groups A and B received the same regimens (albeit in different order), PK data for these two groups were collated, then assessed. For the same reason, PK data from Groups C and D regimens were collated before assessment, as were the PK data from Groups E and F.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Maraviroc, Fosamprenavir and Ritonavir in people with Healthy, run by Garden State Infectious Disease Associates, PA at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 16 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Jan 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmin/Cmax: Steady-state Plasma Amprenavir (APV) Pharmacokinetics ( PK) Following Admin of Fosamprenavir (FPV) 1400mg BID, FPV 700mg/Ritonavir (RTV) 100 mg BID, or FPV 1400mg/RTV 100mg QD With and Without Concurrent (Maraviroc) MVC 300mg BID. (time frame: Day 14 of the FPV 1400mg BID, FPV 1400mg/MVC 300mg BID, FPV 700mg/RTV 100mg BID, FPV 700mg/RTV 100mg/MVC 300mg BID, FPV 1400mg/RTV 100mg QD, and FPV 1400mg/RTV 100mg QD plus MVC 300mg BID regimens). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00764465.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2016.
