Prospective Observational Epidemiologic Study of Maraviroc's Safety

Completed
Conditions
Human Immunodeficiency Virus
Interventions
Drug: Optimized background antiretroviral drug regimen without maraviroc
Registration Number
NCT00665561

Primary Outcome Measures
NameTimeMethod
Density Rate Per 1000 Participant-Years for Incidence of Viral EncephalitisUp to 5 years following enrollment

Density rate per 1000 participant-years for incidence of viral encephalitis was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI.

Density Rate Per 1000 Participant-Years for Incidence of Death Due to Any CauseUp to 5 years following enrollment

Density rate per 1000 participant-years for incidence of death due to any cause was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI.

Adjusted Density Rate Per 1000 Participant-Years for Incidence of Centers for Disease Control and Prevention Category C Aids-Defining Opportunistic InfectionsUp to 5 years following enrollment

Adjusted density rate per 1000 participant-years for incidence of centers for disease control and prevention category c aids-defining opportunistic infections was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with treatment as the main effect, propensity score (PS) quartile and imputed Framingham score (FS) as covariates in the model to obtain the adjusted rate and CI.

Percentage of Participants With All-Cause MortalityUp to 5 years following enrollment

All-cause death was defined as the death due to any cause during the course of study.

Density Rate Per 1000 Participant-Years for Incidence of Centers for Disease Control and Prevention Category C AIDS -Defining Opportunistic InfectionsUp to 5 years following enrollment

Density rate per 1000 participant-years for incidence of centers for disease control and prevention category C acquired immunodeficiency syndrome (AIDS) -defining opportunistic infections was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and confidence interval (CI).

Density Rate Per 1000 Participant-Years for Incidence of All Malignancies (AIDS Defining Malignancies and Non-AIDS Defining Malignancies)Up to 5 years following enrollment

Density rate per 1000 participant-years for incidence of all malignancies as well as its types (categorized as: AIDS defining malignancies and non-AIDS defining malignancies) were reported. AIDS defining malignancies included malignancies due to any of these: cervical cancer, Kaposi's sarcoma or lymphoma; whereas all other malignancies (except AIDS-defining) were non-aids defining malignancies. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI.

Density Rate Per 1000 Participant-Years for Incidence of Liver FailureUp to 5 years following enrollment

Density rate per 1000 participant-years for incidence of liver failure was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI.

Density Rate Per 1000 Participant-Years for Incidence of Myocardial Infarction or Ischemia: Events Adjudicated as 'Definite' or 'Possible'Up to 5 years following enrollment

Density rate per 1000 participant-years for incidence of myocardial infarction or ischemia (definite + possible) was reported. Events of myocardial infarction or ischemia were adjudicated as definite or possible; where definite= an event had definitely occurred; possible =an event had possibly occurred. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI. In this outcome measure, density rate per 1000 participant-years for incidence of myocardial infarction or ischemia (which included sum of definite + possible events) was reported.

Density Rate Per 1000 Participant-Years for Incidence of Myocardial Infarction or Ischemia: Events Adjudicated as 'Definite' or 'Possible' or 'Insufficient Data'Up to 5 years following enrollment

Density rate per 1000 participant-years for incidence of myocardial infarction or ischemia (definite + possible + insufficient data) was reported. Events of myocardial infarction or ischemia were adjudicated as definite or possible or insufficient data; where definite= an event had definitely occurred; possible =an event had possibly occurred; insufficient =insufficient data to determine whether an event had occurred. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI. In this outcome measure, density rate per 1000 participant-years for incidence of myocardial infarction or ischemia (which included sum of definite + possible events + insufficient data) was reported.

Density Rate Per 1000 Participant-Years for Incidence of RhabdomyolysisUp to 5 years following enrollment

Density rate per 1000 participant-years for incidence of rhabdomyolysis was reported. Density rate was calculated as the number of events (n) per 1000 participant-years at risk. Poisson regressions were fit to the categorical events with only treatment in the model to obtain the crude rate and CI.

Poisson regressions were fit to the categorical events with treatment as the main effect, PS quartile and imputed FS as covariates in the model to obtain the adjusted rate and CI.
