Trial Outcomes & Findings for Comparison of Liquid Kaletra and Low Dose Kaletra Tablets (NCT NCT00762320)

NCT ID: NCT00762320

Last Updated: 2014-03-24

Results Overview

Number of participants who had no clinically significant deterioration in absolute CD4 and % CD4 count for the duration of the study. Absolute CD4 and Percent CD4 counts were determined by single or dual platform analysis performed on blood samples by Phoenix Children's Hospital Laboratory, Sonora Quest Laboratory or Labcorp Laboratory. Clinically significant change was determine to be a deterioration in both Absolute CD4 to less than 500 and %CD4 to less than 25%.

SECONDARY outcome

Timeframe: Baseline, 1 month

Population: Patients had to be able to read and write to complete the patient satisfaction questionnaire, so an arbitrary age of 7 was selected and patients under the age of 7 did not complete the patient satisfaction questionnaire. All 5 of the patients over the age of 5 completed the questionnaire and were analyzed.

Patient Satisfaction Survey. Eight item Likert scale of patient satisfaction with their HIV treatment regimen for patients 7 years of age and older. Items scores are summed to compute a total score. Total scores are reported with a minimum of 0 and a maximum of 32, with higher scores indicating higher satisfaction.

SECONDARY outcome

Timeframe: Baseline, 1 month, 3 months, 6 months

Population: All participants analyzed

Cumulative tally of symptoms for each patients across all visits. Targetted symptoms were asked for at each visit and patients and parents were encouraged to report additional symptoms that were experienced. Each patient got a score for the total number of symptoms at each visit. Scores were totalled, but it the same symptoms occurred continuously it was counted as 1 symptom.
