Investment Grants: Bringing Bioengineers to Cure HIV
Request for Proposals
amfAR’s $100 million Countdown to a Cure initiative is aimed at developing the scientific basis of a cure for HIV by the end of 2020. The urgency of our goal demands that we direct our funding to studies that uncover vital knowledge directly applicable to curing HIV in people living with HIV/AIDS. amfAR expects that this RFP will solicit revolutionary ideas and unconventional approaches that inform, design and evaluate curative interventions.
Persistent reservoirs of virus not cleared by antiretroviral therapy (ART) represent the main barrier to a cure for HIV and, as evidenced by the “Berlin patient,” removing the reservoir is one mechanism by which a cure can be accomplished. amfAR intends to fund research that explores all curative approaches, including reservoir removal, as well as other mechanisms that would result in ART-free remission without the risk of transmission for at least five years. We encourage the submission of proposals that explore novel, high-risk, and potentially high-impact ideas.
amfAR’s Investment Grants aim to harness technology developed by bioengineers to solve the problems posed by the viral reservoir. Recent advances in nanomachines, synthetic biomarkers, in vivo sensors, multi-omic single cell platforms and other technologies have yet to be evaluated for their usefulness in curing HIV. Investment Grants provide a funding mechanism through which potentially groundbreaking, early stage approaches are encouraged, regardless of risk or scalability, by requiring collaborations between bioengineers and HIV cure scientists.
Funding Opportunity Description: Investment Grants
Investment Grants are milestone-driven grants that provide funding of up to $1.5 million over four years in three phases. See table below for funds allotted to each phase. Applicants must be HIV scientists focusing on cure research and are required to collaborate with bioengineers employing technologies that have the potential to address the specific areas of interest. Bioengineers interested in applying are required to collaborate with HIV cure scientists.
Investment Grants are expected to be completed in four years and the length of each phase should be dictated by the PI, however, reasonable time allocations should be made to ensure completion of all phases within the prescribed time.
Specific Areas of Interest
The main barrier to a cure for HIV is the presence of a viral reservoir that persists despite suppressive ART. The majority of the viral reservoir is in CD4+ T cells in the form of provirus—HIV DNA that is integrated into the host genome. To date, there is no single or combined signature of biomarkers that can distinguish the viral reservoir from uninfected cells during suppressive ART. Eliminating or permanently disabling the viral reservoir will result in a cure for HIV. Thus, specific areas of interest are:
biomarkers or molecular signatures that can distinguish the reservoir from uninfected cells in vivo during suppressive ART
mechanisms to induce cell death specifically in HIV-infected cells in vivo
mechanisms to permanently disable the provirus in vivo
The goal of each area of interest is to develop tools that will, at the end of four years, be ready for Phase I clinical trials. Each proposal must address the specific area of interest in vivo in an appropriate animal model. Research plans that do not include an in vivo component will not be reviewed.
The proposed research plan must be responsive to at least one specific area of interest and delineate all phases of the work for all milestones within that area. Research plans falling outside of the prescribed areas of interest will not be considered. Applicants should ensure that the research plan is written for reviewers who are well-versed in the HIV cure field.
amfAR will not consider iterations of previously tested ideas that resulted in only modest advances or studies that would result in incremental knowledge. Collaborations must be meaningful and capitalize on the verifiable expertise of both parties. This RFP does not fund prevention studies or non-biomedical research-based activities.
Applicants may submit inquiries to amfAR (firstname.lastname@example.org) regarding the development of research plans to ensure that such plans fit within the intended scope of this RFP. No phone calls will be accepted. Responses to all inquiries received will be posted here as Frequently Asked Questions (FAQs). The FAQ will be updated periodically, so please check for the current version before e-mailing an inquiry.
collaborative work plan involving the HIV cure scientist and the bioengineer
a device, technology or tool that has not been tested in HIV
in vivo studies in an appropriate animal model
the use of clinical HIV viral isolates or SIV model viruses if using non-human primates
the use of clinically relevant tissues and primary cells
Milestones and Tasks
Investment Grant funds will be distributed in three phases. Advancement to the next phase is dependent on 1) the achievement of a predetermined and mutually agreed upon milestone and 2) on amfAR’s research priorities. Provisions can be made and negotiated during the performance period as needed to ensure maximum agility, allow for creativity, and keep pace with innovations in the field. Milestones should be proposed by the investigator at the LOI stage and will be negotiated at the time of notice of award.
amfAR expects that the research plan will be completed in four years and that each phase is allotted a reasonable amount of time to be completed. In order for amfAR to evaluate whether the proposed work is on course for completion during the phase and in line with stated objectives, project metrics will be evaluated through progress reports.
Generally, we expect technology development to be accomplished in Phase I. Phase II should translate that technology in vitro to primary cells and/or tissues. Phase III should test the technology in vivo in an appropriate animal model. However, amfAR understands these milestones can differ significantly depending on the stage at which each technology is beginning. Thus, reasonable milestones outside of that described above will be reviewed.
Example of Proposed Milestones and Tasks
A team proposes that a nanomachine, Death Star, which currently detects influenza in vitro and activates apoptosis via caspase X, can be modified to cure HIV. The team is addressing specific area #2- mechanisms to induce cell death specifically in HIV-infected cells in vivo. This team will write milestones that redesign the technology in Phase I, test the technology in primary cells in Phase II and test it in non-human primates in Phase III.
Their milestones and tasks could be written as follows:
Milestone I- Demonstrate that Death Star specifically detects HIV/SIV viral isolates and activates caspase X only when HIV is detected.
Task 1- Redesign Death Star to detect clinical HIV viral isolates and two SIV model viruses. Criteria for success: Activation of caspase to at least 80% of positive control will be detected in 90% of HIV clinical viral isolates and two SIV model viruses.
Task 2- Test redesigned Death Star for specificity to HIV/SIV vs. other clinically relevant viruses for caspase X activation. Criteria for success: 0% caspase activation is observed in samples testing Human Endogenous Retrovirus, Herpes Simplex Virus, Human papilloma virus, Rhinovirus and Influenza virus.
Application Review and Selection Process
Selection of applications is a four-step process, as follows:
Letters of Intent (LOIs) are reviewed by amfAR staff to ensure that eligibility requirements are met and that the research proposed is in line with amfAR objectives and is responsive to the RFP. LOIs that meet the criteria proceed to a peer review process.
LOIs are reviewed by leading HIV experts and scored based on the following criteria:
- expected impact on HIV cure
- innovation and novelty of the proposed work
- plan to overcome obstacles described with the technology/tool/platform proposed
- competency and track history of members of the team
- feasibility of work plan
Applicants with the highest-scoring LOIs are invited to submit full applications. Full applications are reviewed by members of amfAR’s Scientific Advisory Committee and a select group of bioengineers. Each application will be discussed during an in-person meeting to assess the merit of each application with respect to:
- expected impact on HIV cure
- ability of the team to overcome obstacles in reaching milestones
- innovation and novelty of the proposed work
- possible scientific or budgetary overlap
Successful applications are chosen based on reviewer comments and on amfAR priorities.
Applications are accepted from nonprofit research institutions worldwide; applications are not accepted from individuals or for-profit entities. However, although the Principal Investigator must be from the applicant institution, research teams may include members from, and budgets may include subcontracts or subawards to, for-profit entities.
Must hold a doctoral level degree; it is not required that the principal investigators hold a faculty-level position.
Collaborating PIs need not be from the same institution.
The HIV cure PI will be expected to lead one of the component projects, coordinate the development, implementation and analysis of the project as a whole, and be responsible for overall financial management and the preparation and submission of required reports.
There is no direct cost maximum; however, indirect costs may not be greater than 20% of direct costs, less subawards. The total cost maximum is $1,500,000.
This RFP solicits projects to be completed in the four-year period starting February 1, 2017.
