Measure
Enfuvirtide+PI+ARV's
Eligible participants received Fuzeon® (enfuvirtide) 90 milligram (mg) subcutaneously (SC) two times a day (bid) for 24 weeks plus new protease inhibitor (PI) (darunavir/ritonavir) plus other investigator-choice antiretrovirals (ARVs). Participants selected their preferred injection device among the following three options: 27 gauge (G) ½" needle/syringe, 31G 8 millimeter (mm) needle/syringe or Biojector 2000 (B2000) needle-free injection device (NFID).

Population: Analysis was performed on the Intent-to-treat (ITT) Population.The ITT Population included enrolled participants who received at least one dose of study medication and had at least one post baseline efficacy assessment. Maximum number of participants available at the particular time point were analysed and reported.

Adherence to ENF treatment regimen was calculated using the participant's response to the query on the "Participant Adherence Questionnaire case report form (CRF)" about injections incomplete or missed in the last 4 days preceding the study visit. The percentage adherence to the ENF regimen at each study visit is given by: % Adherence = (\[8 - the number of doses missed\] / 8) x 100. The number and percentage of participants adhering to the ENF regimen were presented by adherence category (100%, ≥95%, ≥90% and ≥85%) at Weeks 4, 12, and 24.

SECONDARY outcome

Timeframe: Week 1 to Week 24

Population: Analysis was performed on the Safety Population. The Safety Population included all the participants who received at least one dose of trial medication and had a safety follow-up.

Injection site reactions (ISRs) referred to any localized sign or symptom, including erythema, induration, pruritus, nodules, ecchymosis (degree of bruising/ discoloration), and pain/discomfort. Injection site reactions were monitored by trained study personnel at weeks 1, 4, 12, 16, and 24. Interruption of ENF for toxicity management of recurrent local grade 3 or 4 ISRs until the sign or symptom resolved to grade 2 was at the discretion of the investigator. Any individual injection site signs or symptoms meeting the criteria for a serious adverse event (SAE) had to be reported as an SAE. In the event of a serious ISR, the participant was to immediately discontinue ENF and withdraw from the study. If the participant was not already hospitalized, serious ISRs required a clinic visit within 72 hours of the event.

Eligible participants received enfuvirtide 90 mg bid, SC injection for 24 weeks plus new PI (darunavir/ritonavir) plus other investigator-choice ARVs. Participants selected their preferred injection device among the following 3 options: 27G ½" needle/syringe, 31G 8 mm needle/syringe or B2000 NFID.
Percentage of Participants With 1 or More Injection Site Reactions Meeting the Criteria of an Serious Adverse Event
0 Percentage of participants

SECONDARY outcome

Timeframe: Week 24

Population: Analysis was performed on the Safety Population. The Safety Population included all the participants who received at least one dose of trial medication and had a safety follow-up. Maximum number of participants available at the particular time point were analysed and reported.

Injection site reactions (ISRs) referred to any localized sign or symptom, including erythema, induration, pruritus, nodules, ecchymosis (degree of bruising/ discoloration), and pain/discomfort. Injection site reactions were monitored by trained study personnel at weeks 1, 4, 12, 16, and 24. Grades 0 through 4 are a measure of intensity, not seriousness. Thus, a grade 3 or grade 4 sign or symptom could be severe, but not necessarily serious. Only active, ongoing ISR were counted. The maximum severity grade for pain/discomfort since the last visit at any injection site was recorded whether or not the maximum severity of pain/discomfort was ongoing at the time of clinical evaluation.
