Revised Simplified Algorithm for Treatment Eligibility for HIV (SLATEII) — SLATEII  

HIV/AIDS Clinical Trial

Official title: Randomized Evaluation of a Revised, Simplified Clinical Algorithm for Identifying Patients Eligible for Immediate Initiation of Antiretroviral Therapy for HIV (SLATEII)

Status Completed

Clinical Trial Summary

In its 2017 revision of the global guidelines for HIV care and treatment, the World Health Organization called for rapid or same-day initiation of antiretroviral treatment (ART) for eligible patients testing positive for HIV. In sub-Saharan Africa, where most HIV patients are located, studies continue to document high losses of treatment-eligible patients from care before they receive their first dose of antiretroviral medications (ARVs). Among facility-level reasons for these losses are treatment initiation protocols that require multiple clinic visits and long waiting times before a patient who tests positive for HIV is dispensed an initial supply of medications. Simpler, more efficient, accelerated algorithms for ART initiation are needed, including strategies for rapid initiation in patients with symptoms of tuberculosis, most of whom do not have active TB. In July 2017, the original SLATE study (SLATE I) completed enrollment in South Africa. One of the most striking findings of the study so far is the large proportion of patients who "screened out" of the SLATE algorithm and were referred for additional services rather than started on ART immediately. Among 298 patients assigned to the intervention arm and evaluated for immediate treatment eligibility under the SLATE algorithm, 149 (50%) screened out, two thirds of these (100/149) due to symptoms of TB. The vast majority of the TB suspects (93/100, 93%) tested negative for active TB. The SLATE II study will revise the original SLATE algorithm to provide a pathway for immediate ART initiation for some patients with TB symptoms. Under SLATE II, patients with TB symptoms will be clinically evaluated by the study nurse and will receive a urine point of care LAM (lipoarabinomannan antigen of mycobacteria) test. Those with milder symptoms and a negative LAM test will be offered immediate ART. Those with more serious symptoms and/or a positive LAM test will be asked to return the next day to receive TB test results and either immediate ART or TB treatment. All intervention arm patients (symptomatic and asymptomatic) will be asked for a sputum sample for Xpert testing, and positives will be contacted on the next day. The SLATE II algorithm will also incorporate other improvements identified from SLATE I.

Clinical Trial Description

SLATE II is be a pragmatic, individually randomized evaluation to determine the effectiveness of the revised algorithm in increasing ART initiation, compared to standard care, among non-pregnant adult patients. Six hundred HIV-infected adult patients not yet on ART will be enrolled during a routine clinic visit and randomized to receive the intervention or standard care. Patients in the intervention arm will be administered a revised version of the SLATE screens, including the TB add-on; those found eligible under the algorithm will be offered immediate treatment initiation, while those who are not eligible will be referred for standard clinic care. Patients in the standard arm will be referred for ART initiation under standard clinic procedures. All care after the initial visit will be by the clinic under standard care. Primary outcomes will be ART initiation within 7 days of study enrollment and viral suppression within 8 months of study enrollment. The study is being conducted at three healthcare facilities (clinics) in South Africa. In September 2017, the South African National Department of Health instructed all clinics to offer same-day ART initiation to eligible patients but provided little guidance on determining eligibility. SLATE II will help to create such guidance. If successful, it will improve on the SLATE approach to collecting and interpreting a minimum set of patient data that will avoid delaying treatment initiation for the majority of patients who are eligible for immediate ART, while deferring initiation in the minority who should not start immediately. ;
