Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The total study duration was 36 weeks. Prior to enrolling in the study, participants had a chest X-ray. Participants were randomly assigned to receive LDMTX or placebo for 24 weeks. Participants continued taking their antiretroviral (ARV) medications as usual; ARVs were not provided by the study. At study entry, participants underwent a medical and medication history, physical examination, blood collection, and adherence assessments. From study entry through Week 1, participants received either 5 mg of LDMTX or placebo once a week. For participants who were clinically stable at the Week 1 study visit, the dose of LDMTX or placebo was increased to 10 mg once a week through Week 12. For participants who were clinically stable at the Week 12 study visit, the dose of LDMTX or placebo was increased to 15 mg once a week through Week 24. Participants who did not meet the criteria for dose escalation were re-evaluated at the following study visit. In addition to LDMTX or placebo, all participants also received 1 mg of folic acid once a day from study entry throughout Week 24. After taking the final dose of LDMTX or placebo, all participants continued taking folic acid for an additional 4 weeks.
Post-entry visits occurred at Weeks 1, 2, 4, 8, 12, 18, 24, and 36. These included a physical examination, blood collection, and adherence assessments; an arm ultrasound test was performed at Weeks 12 and 24. At Week 2, some participants took part in a pharmacokinetic (PK) assessment, which involved undergoing a blood collection several times over a 6-hour period.
