A Study to Assess the Efficacy of Raltegravir (Isentress®), Administered in Combination With Other Antiretroviral Drugs as Treatment for Adults and Older Adults Infected With the Human Immunodeficiency Virus 1 (HIV-1)(MK-0518-145) (Wirksamkeit Von Isentress® Unter Praxisbedingungen) (WIP)

15. dubna 2016 aktualizováno: Merck Sharp & Dohme LLC

A Non-interventional Cohort Study for the Assessment of the Efficacy of RALTEGRAVIR 400 mg Administered Twice Daily in Combination With Other Antiretroviral Drugs to Treat Infection With the Human Immunodeficiency Virus 1 (HIV-1) in Adults and Aging Patients (≥ 50 Years) Under Conditions That Are Representative of the Nationwide Treatment of HIV-positive Patients in Germany

This is an observational, non-comparative, multicenter, open-label study. Participants will be treated with Raltegravir according to standard clinical practice, and monitored over a total period of 96 weeks. In an extension to the study (Amendment 1), a new cohort of aging participants (≥ 50 years) will be recruited and monitored over a total period of 48 weeks. Participants who stop taking Raltegravir before the end of the 96-week period or 48-week period, respectively, will be followed up for 3 months after discontinuing the drug. The primary objective is to determine the proportion of participants with a human immunodeficiency virus (HIV)-1 viral load < 50 copies/mL after 48 weeks of treatment with Raltegravir.

Change From Baseline in Mean Framingham Risk Score for the 10-Year Cardiovascular Risk in Aging Participants After 48 Weeks of Raltegravir Treatment
Časové okno: Baseline and 48 weeks
Mean Framingham Risk for 10-year cardiovascular risk was determined in aging participants (>=50 years old at initiation of raltegravir treatment). Points were allotted for each of following 8 risk factors : sex, age, systolic blood pressure, treatment for hypertension, smoking, diabetes, total cholesterol, and high-density lipoprotein. The sum of the points for each participant was assigned a percent 10-year cardiovascular risk on a lookup table, and could range from 0% to 100%. The mean Framingham Risk for 10-year cardiovascular risk was then calculated for the analysis population. The change from baseline was calculated as Baseline minus Week 48; a positive change indicates reduced risk. This Outcome Measure was added with Amendment 1 and applies only to aging participants.

Change From Baseline in Mean D:A:D Risk Score for the 5-Year Cardiovascular Risk in Aging Participants After 48 Weeks of Raltegravir Treatment
Časové okno: Baseline and 48 weeks
Mean Data Collection on Adverse Events of Anti-HIV Drugs (D:A:D) Risk Score for 5-year cardiovascular risk was determined in aging participants (>=50 years old at initiation of raltegravir treatment) at Baseline and after 48 weeks of raltegravir treatment. The score included the following 8 risk factors: sex, age, systolic blood pressure, family cardiovascular disease history, current smoking, previous cigarette smoker, diabetes, total cholesterol, high-density lipoprotein, currently on indinavir, currently on lopinavir, currently on abacavir, duration and current use of indinavir and duration and current use of lopinavir. The D:A:D Risk Score is interpreted as low: <1%; moderate: 1-5%; high: 5-10%; and very high: >10%. The change from baseline was calculated as Week 48 minus Baseline; a positive change indicates increased risk. This Outcome Measure was added with Amendment 1 and applies only to aging participants.
