What Perinatal HIV Research Unit does

The Perinatal HIV Research Unit (PHRU) is a South African non-profit clinical research organization founded in 1996 and headquartered at Chris Hani Baragwanath Academic Hospital in Soweto, operating as a research division of the University of the Witwatersrand under the Wits Health Consortium. PHRU conducts multi-disciplinary, GCP-compliant clinical research across HIV prevention (vaccines, PrEP, long-acting agents), HIV treatment optimization (including paediatric, maternal, and adolescent populations), tuberculosis (including drug-resistant TB and the M72 vaccine trial), and COVID-19 vaccine studies, operating five research sites across four South African provinces (Soweto, Aeroton, Matlosana, Botshabelo, Limpopo) and participating in landmark multi-country trials such as PURPOSE 1. Its research portfolio is delivered through NIH-funded networks — HVTN, HPTN, ACTG, and IMPAACT — together with internally branded units (NM Syndicate, Vaccines Research Centre, Social & Bio-behavioural Research Division) and supported by an in-house support services stack: DataLab for data management and AI metadata preparation, Statistics Support for study design and machine learning, GCP/GCLP-certified Pharmacy Services for clinical trial medications, Regulatory Services for SAHPRA and ethics submissions, and the CLEAR Laboratory for PBMC processing, cryopreservation, and biostorage.

PHRU is fully grant-funded, with revenue derived from research grants and clinical trial agreements with the National Institutes of Health (via DAIDS), PEPFAR, the Bill & Melinda Gates Foundation, the South African Medical Research Council, and pharmaceutical sponsors including Gilead Sciences and the Gates Medical Research Institute. The organization does not sell commercial products and operates a community-partnered go-to-market model: four Community Advisory Boards (including an Adolescent CAB / Youth Talk), 26 partnered Soweto TB clinics, and direct community outreach in high-burden townships drive trial recruitment, while ~100 peer-reviewed publications annually provide scientific credibility and inform WHO and FDA recommendations. Notable milestones include the 1996-1997 court case compelling South African government provision of nevirapine (in which PHRU was a plaintiff), the 2001 launch of the first HIV vaccine trial in South Africa, the 2020 Sisonke study vaccinating nearly 500,000 healthcare workers against COVID-19, and the 2025 PURPOSE 1 trial demonstrating 100% efficacy of lenacapavir for HIV prevention among cisgender women.

Leadership combines internationally credentialed researchers — including Executive Director Prof Neil Martinson (Johns Hopkins MPH), Deputy Executive Director Dr Avy Violari (IMPAACT site leader), Non-Executive Director and co-founder Prof Glenda Gray (NRF A-rated scientist, former SAMRC President and CEO), and Lead Biostatistician Prof Kennedy Otwombe (140+ publications) — with site-level directors across each province. Customer-facing outputs are delivered to study participants (HIV-positive pregnant women, adolescents and young women, MSM, TB patients and contacts, healthcare workers) and to global health sponsors; PHRU functions as a contract research organization embedded within an academic institution, with operational scale of 101-250 employees distributed across the five sites.

Core offering

PHRU conducts multi-disciplinary clinical research in HIV, TB, COVID-19, and related infectious diseases through five dedicated research sites across South Africa. The unit operates through NIH-funded research networks (HVTN, HPTN, ACTG, IMPAACT) and investigator-initiated studies, supported by in-house DataLab, Statistics, Pharmacy, Regulatory, and CLEAR Laboratory services. PHRU also provides clinical care, prevention services, and community engagement for study participants in high-burden South African communities.

Product overview

The Perinatal HIV Research Unit (PHRU) is a research institution offering a comprehensive portfolio of clinical research services rather than a traditional product company. The organization operates through multiple research networks (NM Syndicate, HVTN, HPTN, ACTG, IMPAACT) and a Vaccines Research Centre, all supported by core service divisions: DataLab for data management and API integrations, Statistics Support for study design and machine learning, Pharmacy Services for clinical trial medications, Regulatory Services for compliance, and the CLEAR Laboratory for specimen processing. The PHRU also conducts Social & Bio-behavioural research. This structure integrates clinical trials infrastructure with specialized support services to enable multi-site research across HIV, TB, COVID-19, and other infectious diseases throughout South Africa.

Broad incumbents

• HIV Vaccines Trials Network (HVTN): HVTN is the NIH-funded global network coordinating HIV vaccine trials of which PHRU is a member site. It is comparable as the overarching research consortium governing the trials PHRU executes, providing peer benchmarks in network governance and protocol allocation.
• International AIDS Vaccine Initiative (IAVI): IAVI is a global product-development organisation that funded PHRU's HIV Vaccine Clinical Trials Unit in 2001 and continues to co-sponsor protocols. It is comparable as a partner/peer organisation shaping the HIV vaccine pipeline PHRU serves.

Regional players

• Centre for Infectious Disease Research in Zambia (CIDRZ): CIDRZ is a Lusaka-based research organisation running PEPFAR/NIH-funded HIV and TB trials in Zambia. It is comparable as a regional African peer performing the same grant-funded clinical-research mission under similar public-sector constraints.

Direct peers

• Desmond Tutu HIV Foundation: Based at the University of Cape Town, the Desmond Tutu HIV Foundation conducts HIV prevention and vaccine trials with a community-based model. It competes with PHRU for adolescent and key-population trial enrolments across South African sites.
• Africa Health Research Institute (AHRI): AHRI is a KwaZulu-Natal-based research institute running HIV/TB clinical trials, population cohorts, and immunology studies. It is a fellow NIH-network-affiliated site and competes with PHRU for HPTN, HPTU, and ACTG protocols.
• The Aurum Institute: Aurum is a large South African health-research NGO specialising in TB, HIV, and vaccine trials with multiple clinical sites. Like PHRU, it is grant-funded (NIH/PEPFAR/Gates), runs GCP-compliant laboratories, and competes for HPTN/HVTN protocols.
• Centre for the AIDS Programme of Research in South Africa (CAPRISA): CAPRISA is a UNAIDS-collaborating centre in Durban running HIV prevention and treatment trials, TB research, and vaccine studies. It directly competes with PHRU for NIH network site selection and sponsor-led protocols in South Africa.
• Wits Reproductive Health and HIV Institute (Wits RHI): Wits RHI is a sister institute at the University of the Witwatersrand running large-scale HIV prevention, PrEP, and adolescent trials. It shares institutional affiliation and overlapping investigator networks with PHRU and competes for the same grant-funded research mandates.

Others
