Abstract
Despite remarkable progress achieved in decreasing HIV transmission and AIDS-related deaths in the last decade due to development of over 30 antiretroviral drugs, HIV continues to spread in a virtually uncontrolled manner. An effective HIV vaccine remains one of the priorities of HIV/AIDS research and will always be the best solution and likely key to any strategy for halting the AIDS epidemic. The biggest challenge in developing such a vaccine is the enormous HIV variability, which dwarfs that of any other virus except hepatitis C virus. However, all parts of HIV cannot easily change; to remain alive, HIV has to keep some smaller regions of its proteins more or less constant to maintain function. Our vaccine strategy takes advantage of this and focuses the body defenses on these conserved parts of HIV, its Achilles heel. Because conserved regions are common to most of the global HIV variants, the vaccine, if successful, could be used in Africa, Asia, Europe, America and Australia: it would be universal. The 1st generation conserved-region vaccine was very safe and induced strong immune responses in adult volunteers in the UK and Africa. In 2014, the pharmaceutical company GSK acquired a small biotech company, which developed one of the benign viruses we used for vaccine delivery, and unilaterally decided that we could no longer use the jointly owned vaccine in high risk people. Thus we needed to switch to an alternative vaccine virus and this provided an opportunity to also substantially improve the 1st generation vaccine. These modifications are based on our experience from human vaccine testing and other developments in the HIV vaccine field over the last 10 years since its original design. Thus, the 2nd generation vaccine was born, using a new vaccine virus (ChAdOx1) owned by Oxford University and combining conserved regions with computer-designed proteins (mosaics), which significantly increase the vaccine match to global HIV variants. (Note that even the highly conserved regions are still somewhat variable.) Vaccines should match circulating HIVs as much as possible to stop them efficiently. The 2nd generation vaccines have been constructed, shown to induce strong immune responses in animal models and are now bound for testing in human volunteers. The requested funds will allow to us see how well the 2nd generation vaccine works in trying to get rid of HIV from already infected individuals and for larger scale testing in HIV-1 negative healthy volunteers in Africa. The latter study will aim first evidence that the vaccine can stop HIV from infecting healthy people. The funding will also allow clinical testing of the vaccine enabling further improvements including some new aimed at keeping ahead of HIV.
Technical Summary
Development of an effective vaccine against HIV/AIDS remains one of the top global health priorities even in the context of broader prevention landscape. It is generally accepted that development of HIV vaccine is a gradual iterative process that will take many years. It is very positive that significant inroads have been made into identifying what constitutes both protective T cells and broadly neutralizing Abs (bnAb) for this most difficult of vaccines.
The biggest challenges for vaccines are HIV variability and escape. Compelling evidence for an important role of CD8 T cells in controlling HIV has accumulated over the last 30 years. My group is taking a multipronged approach to HIV T-cell vaccine development combining our experimental data with novel vaccine strategies. The hypothesis we pursue is that focusing T cells on the functionally conserved regions of HIV proteins will enable early control or elimination of the transmitted/reactivated viruses. To achieve this, the vaccines must match as much as possible all HIV variants and the T cells must be robust enough to stay strong when facing natural infection, altering the natural immunodominance.
This PG Renewal will support a team of scientists led by Tomas Hanke, who are at the heart of a highly rational and promising T-cell vaccine approach. We demonstrated the concept of the conserved region strategy in European and African HIV seronegative adults and also in infected patients on ART. We are now adding a new element to the vaccine, the mosaic concept and are moving towards testing this much improved 2nd generation vaccine for HIV cure and small efficacy trials. The aim for the latter will be to complement induction of Abs when bnAb vaccines remain suboptimal. In the next 5 years, we will develop next generation of vaccine vectors and immunogens; evaluate the induction and role of non-canonical CD8 T cells for human vaccine use; asses the role of conserved T-cell responses in HIV cure and prevention.

Planned Impact
Who will benefit from this research?
Since the first report of AIDS in 1981, an estimated 60,000,000 people have become infected with HIV-1, of whom some 25,000,000 have died. Over 90% of new infections take place in countries with limited resources. Globally the rate of new infections has decreased by 33% since year 2001. Nevertheless in 2013, still 240,000 children became newly infected with HIV-1 and 50 young women became infected every hour, thus a control of the HIV-1 epidemic remains one of the global health priorities.
Effective preventive vaccine against HIV-1 can avert millions of new infections, empower women, protect children, circumvent the stigma facing men-who-have-sex-with-men, and help many other beyond the reach of today's HIV-1 treatment and prevention options. Millions of already infected people around the word will benefit from HIV cure, either functional (drug-free control of HIV-1) or sterile (complete elimination of the virus from the body).
How will they benefit from this research?
ART has revolutionized survival, but is far from an ideal solution, because antiretroviral drugs are not available on a regular reliable basis in many resource-poor settings, they have long-term side effects, their effective use requires rigorous daily compliance and the circulating and/or transmitted viruses develop resistance. In any case, ART alone is unable to eradicate the virus because of an inaccessible pool of HIV-1-infected cells, in which the virus is dormant (the proviral reservoir). Thus, with or without reactivation by latency reverting agents, effective T-cell vaccine will be a key to HIV cure. The gained understanding and approach stimulating CD8+ T cells specific for conserved regions, would be greatly preferable to simply reactivating the pre-antiretroviral treatment T-cell responses that had failed to control the virus. Similarly, efficient and early recognition of transmitted/founder viruses will control the virus spread and prevent damage to the immune system in healthy exposed individual. Our strategy is applicable to other immunological problems where variability is a major roadblock in developing effective preventive or therapeutic tools.
The MRC Programme Grant Renewal proposes science on the forefront of the biotechnology engineering and HIV-1 vaccine development, thus strengthening the UK's world-class excellence in science, fostering industrial leadership to support business including innovation by small and medium-sized enterprises (Immune Design (US), Clinical Biomanufacturing Facility) and even big Pharma will become re-engagement if a real promise is observed in an efficacy trial. Bioengineering is a proven driver of a long-term sustainability and economic growth, we shall demonstrate the feasibility and functional validation of novel designs and biotechnologies developed by academia and manufactured by industries, spur scientific innovation across a broad sector of public and animal health and contribute to educated societal debates on issues associated with novel biotechnologies.
Ultimately, vaccine research will provide a basis for clinical decision making and policy-making for governments, policy-makers and advocates to develop evidence-based policies and advocacy aiming at prioritizing investments in HIV-1 research (clinical and basic science), allowing for an efficient use of limited funds, supporting research that has a greater potential to deliver results at population level.

| Description | Evidence before T cells play an important role in the control of HIV infection and may be particularly useful for HIV-1 cure by killing cells with reactivated HIV-1. Evidence is emerging that not all T-cell responses are protective and only those targeting conserved regions of HIV-1 proteins are effective, but typically immunologically subdominant, while those recognizing hypervariable, easy-to-escape immunodominant 'decoys' do not control viremia and do not protect from a loss of CD4 T cells. We pioneered a vaccine strategy focusing T-cell responses on the most conserved regions of the HIV-1 proteome using an immunogen designated HIVconsv. T cells elicited by the HIVconsv vaccines in HIV-uninfected UK and Kenyan adults inhibited in vitro replication of HIV-1 isolates from 4 major global clades A, B, C and D. Added value Under the present award, we demonstrated the concept that epitopes subdominant in natural infection, when taken out of the context of the whole HIV-1 proteome and presented to the immune system by a potent simian adenovirus prime-poxvirus MVA boost regimen, can induce strong responses in patients on antiretroviral treatment and efficiently refocus HIV-1-specific T-cells to the protective epitopes delivered by the vaccine. Implications of all the available evidence Nearly all HIV-1 vaccine strategies currently emphasise induction of broadly neutralizing Abs. The HIVconsv vaccine is one of a very few approaches focussing exclusively on elicitation of T cells and, therefore, can complement antibody induction for better prevention and cure. Given the cross-clade reach on the HIVconsv immunogen design, if efficient, the HIVconsv vaccines could be deployed globally. Effective vaccines will likely be a necessary component in combination with other available preventive measures for halting the HIV-1/AIDS epidemic. |
| Exploitation Route | Depending on the data from each stage of testing, the vaccine strategy is being taken toward assessment of preventive and therapeutic efficacy. |

| Impact | Our work realizes capacity building projects, which take place at African Clinical Research Centers (CRC) with the aim of preparing them for participation in the proposed phase 2a vaccine trial and future HIV-1 vaccine efficacy trials. Thus, at CRCs in Kenya, Uganda and Zambia, and also in Tanzania through the Lake Victoria Consortium for Health Research, capacity building takes place with the following objectives: • To strengthen clinical capacity for the proposed phase 2a vaccine trial though the training of personnel, procuring equipment and updating infrastructure as needed. • To build a sustainable platform for future HIV-1 vaccine efficacy trials by expanding clinical and laboratory infrastructure and establishing field-based clinical and laboratory capacity. • To ensure the availability of diverse, well-characterized key populations and the ability to ethically engage them in a future HIV-1 vaccine efficacy trial through formative research, community outreach and enhanced community engagement models, which will ensure good participatory practice. |
| Title | Identification of HLA-E binding peptides |
| Description | Non-classical class Ib MHC-E molecule is becoming an increasingly interesting component of the immune response. It is involved in both the adaptive and innate immune responses to several chronic infections including HIV-1 and, under very specific circumstances, likely mediated a unique vaccine protection of rhesus macaques against pathogenic SIV challenge. Despite being recently in the spotlight for HIV-1 vaccine development, to date there is only one reported human leukocyte antigen (HLA)-E-binding peptide derived from HIV-1. In an effort to help start understanding the possible functions of HLA-E in HIV-1 infection, we determined novel HLA-E binding peptides derived from HIV-1 Gag, Pol and Vif proteins. These peptides were identified in three independent assays, all quantifying cell-surface stabilization of HLA-E*01:01 or HLA-E*01:03 molecules upon peptide binding, which was detected by HLA-E-specific monoclonal antibody and flow cytometry. Thus, following initial screen of over 400 HIV-1-derived 15-mer peptides, 4 novel 9-mer peptides PM9, RL9, RV9 and TP9 derived from 15-mer binders specifically stabilized surface expression of HLA-E*01:03 on the cell surface in two separate assays and 5 other binding candidates EI9, MD9, NR9, QF9 and YG9 gave a binding signal in only one of the two assays, but not both. Overall, we have expanded the current knowledge of HIV-1-derived target peptides stabilizing HLA-E cell-surface expression from 1 to 5, thus broadening inroads for future studies. This is a small, but significant contribution towards studying the fine mechanisms behind HLA-E actions and their possible use in development of a new kind of vaccines. |

| Description | The first randomised, double blind trial of kick-and-kill HIV cure. Antiretroviral therapy (ART) cannot cure HIV infection because of a persistent reservoir of latently infected cells. Approaches that force HIV transcription from these cells, making them susceptible to killing-termed kick and kill regimens-have been explored as a strategy towards an HIV cure. RIVER is the first randomised trial to determine the effect of ART-only versus ART plus kick and kill on markers of the HIV reservoir. |

| Title | DC 04 |
| Description | Dendritic cell (DC)-based therapeutic vaccines have shown the most promise for controlling HIV replication without antiretroviral therapy (ART). Although two seminal clinical trials demonstrated significant decreases in plasma viremia without ART that were associated with vaccine-induced HIV-specific immune responses, other DC-based vaccine studies have shown equivocal or no virologic efficacy. The disconnect between a DC-based vaccine's theoretical capability, supported by strong in vitro evidence of priming of effector T-cells, and the variable results of clinical trials, highlight important gaps in understanding the determinants of DC vaccine efficacy in vivo. We therefore propose a comparative analysis to confirm prior efficacy of DC vaccines and to test new, innovative DC vaccines with the dual goals of improving virological efficacy and identifying key determinants of DC vaccine efficacy. Specifically, we will conduct an initial phase I/II, randomized, double-blind, pilot study to compare safety and anti-HIV efficacy of four different DC-based vaccines and two corresponding placebos. The trial will evaluate two DC maturation techniques (the prostaglandin E2-matured DCs, which were partially effective in the two seminal clinical trials, and the alpha-type-1 DCs, which have shown improved antigen-presenting and T-cell priming function ex vivo), two HIV immunogens (whole, inactivated, autologous HIV that was partially effective in the two trials, and a pool of HIV peptides covering the most highly-conserved regions in Gag and Pol combined with epitopes known to be associated with control of viremia in untreated HIV-infected individuals), and two dosing strategies (3 vs 6 doses). The primary efficacy outcome will be change in the inducible HIV reservoir from pre-vaccination to 2 weeks after the final vaccine dose. We will also further evaluate the in vivo anti-HIV efficacy of the DC vaccines by performing an extensive analysis of vaccine-induced changes in virologic and immunologic parameters with the secondary goal of identifying immune correlates of vaccine-induced virologic responses. The parameters measured will include residual plasma viremia, the number and transcriptional activity of HIV-infected cells, CD8+ T-cell inhibition of autologous virus replication, the magnitude, breadth, and polyfunctionality of immune responses, and immunoregulatory responses including regulatory T-cells and myeloid-derived suppressor cells. We propose a second clinical trial to assess reproducibility of initial findings from the first trial and to assess the impact of further refinements of DC vaccine designs on efficacy. We have developed pre-specified Go/No-Go criteria for moving forward to a second trial. The decision whether a specific DC vaccine will be evaluated in the second trial will be based on the primary and secondary virologic and immunologic endpoints of the first trial. This innovative, sequential, and iterative approach will evaluate multiple DC vaccines, elucidate determinants of vaccine efficacy, identify immune correlates of vaccine-induced reductions in HIV reservoirs, and provide new insights into the potential for DC vaccines to achieve durable HIV remission without ART. |

| Title | HIV CORE 0052 |
| Description | A phase 1 dose escalation open label trial to assess safety and immunogenicity of candidate ChAdOx1- and MVA-vectored conserved mosaic HIV-1 vaccines, given sequentially to healthy HIV-1/2-negative adult volunteers in Oxford, UK MVA-based vaccines The two MVA-vectored vaccines are called MVA.tHIVconsv3 and MVA.tHIVconsv4. Both were manufactured, labeled and technically released by IDT Biologika GmbH in Dessau-Rosslau, Germany. MVA is an efficient single-round expression vaccine vector that is itself incapable of replication and spread in mammals. Both MVA.tHIVconsv3 and MVA.tHIVconsv4 contain a transgene (insert) coding for 6 conserved HIV regions that are fused together to form a chimeric protein immunogen. These 6 regions are arranged in different unique orders, MVA.tHIVconsv3 as 3-6-2-5-1-4 and MVA.tHIVconsv4 as 4-1-5-2-6-3. Chimpanzee Adenovirus-based vaccine The Chimpanzee Adenovirus-vectored vaccine is called ChAdOx1.tHIVconsv1. It was manufactured, labeled and technically released by Advent S.r.l. in Rome, Italy. The ChAdOx1 vaccine vector is an engineered, non-replicating vector derived from simian adenovirus. ChAdOx1.tHIVconsv1 contains a transgene (insert) coding for 6 conserved HIV regions that are fused together to form chimeric protein immunogen in the region order of 1-2-3-4-5-6. |

| Title | HIV-CORE 006 |
| Description | A Phase 1 Trial of ChAdOx1- and MVA-vectored Conserved Mosaic HIV-1 Vaccines in Healthy, Adult HIV-1-negative Volunteers in Eastern and Southern Africa. MVA-based vaccines The two MVA-vectored vaccines are called MVA.tHIVconsv3 and MVA.tHIVconsv4. Both were manufactured, labeled and technically released by IDT Biologika GmbH in Dessau-Rosslau, Germany. MVA is an efficient single-round expression vaccine vector that is itself incapable of replication and spread in mammals. Both MVA.tHIVconsv3 and MVA.tHIVconsv4 contain a transgene (insert) coding for 6 conserved HIV regions that are fused together to form a chimeric protein immunogen. These 6 regions are arranged in different unique orders, MVA.tHIVconsv3 as 3-6-2-5-1-4 and MVA.tHIVconsv4 as 4-1-5-2-6-3. Chimpanzee Adenovirus-based vaccine The Chimpanzee Adenovirus-vectored vaccine is called ChAdOx1.tHIVconsv1. It was manufactured, labeled and technically released by Advent S.r.l. in Rome, Italy. The ChAdOx1 vaccine vector is an engineered, non-replicating vector derived from simian adenovirus. ChAdOx1.tHIVconsv1 contains a transgene (insert) coding for 6 conserved HIV regions that are fused together to form chimeric protein immunogen in the region order of 1-2-3-4-5-6. |

| Impact | The world needs an AIDS vaccine. The overall aim of the research is to make a significant contribution to the development of an effective HIV vaccine by inducing protective T-cell responses. Such a T-cell vaccine may critically complement vaccines inducing broadly neutralizing antibody (bnAbs) for prevention and be key for HIV cure for people living with HIV (PLWH). We have initiated a series of prevention and cure trials with new improved mosaic vaccines, called HIVconsvX, which target highly conserved regions of HIV and we believe have a real chance to help impact the epidemic. |
