- Description
- Amendment 1: The purpose of Amendment 1 to DARPA-SN-23-40, the Somnus Research Opportunity, is to provide additional information about the previously collected dataset referenced in Option 2 and clarify the dataset description. Changes bolded/highlighted/underlined below. Objective is updated as follows: Objective: DARPA is interested in revolutionary research ideas to assess and modulate the impact of gut microbiota on sleep-wake states and cognitive function across acute sleep deprivation and recovery according to the following 17-month structure. The Somnus study is divided into a base period of performance of 13 months and an option period of 4 months as described below: Base Period: DARPA seeks to identify gut microbiota and downstream biomolecules (e.g., metabolites, lipids, peptides, nucleic acids, etc.) associated with acute sleep deprivation and recovery. Additionally, DARPA is interested in characterizing differences in gut microbiota and associated biomolecules � including circulating molecules detectable in animal blood biospecimens � corresponding to inter-individual variability in the physiological, behavioral, and cognitive effects of sleep pressure as it fluctuates between deprived and recovered states. At the conclusion of the Base Period effort, performers will deliver a list of identified molecules that could be exploited to modulate physiological underpinnings of the cognitive response to changes in sleep pressure. Options: There are two separate option tasks that, if DARPA elects to proceed with both, may be executed in parallel with one another. Option 1: Should the first option task be executed, performers will conduct extended, system-level analyses of datasets obtained in the Base Period, with the goal of identifying putative molecular/biochemical pathways associated with host-microbiome interaction in the gut and resultant molecules in the blood that correspond to sleep pressure and its effects on cognitive function. Option 2: Should the second option task be executed, the government will provide a previously collected dataset at the start of this task that includes human blood biospecimens and cognitive performance measures collected prior to and following a period of acute sleep deprivation across a cohort of approximately thirty (30) participants. The goal of this option is to verify that molecules, or their homologs, identified during the Base Period of Somnus, correspond to changes in sleep pressure in humans. Anticipated Structure is updated as follows: Anticipated Structure: The Somnus study duration is 17 months. The period of performance (PoP) includes obtaining local Institutional Animal Care and Use Committee (IACUC) and U.S. Army Medical Research and Development Command Animal Care and Use Review Office (ACURO) approvals as well as successfully identifying molecules and mechanisms of host interactions with the gut microbiome that are associated with the restorative effect of sleep on cognitive performance in an animal model. Should Option 2 be exercised, the PoP also includes obtaining local Institutional Review Board (IRB) and U.S. Army Medical Research and Development Command Office of Human Research Oversight (OHRO) approvals to analyze a previously collected dataset of human blood biospecimens provided by the government, in order to identify circulating biomolecules associated with sleep pressure and cognitive function prior to and following acute sleep deprivation, if required. We anticipate that the human cohort will consist of healthy individuals who undergo a single night of sleep deprivation, with cognitive performance measures and blood biospecimens collected prior to and throughout a period of sleep deprivation, as well as following recovery sleep. For the purpose of budgeting, Somnus proposers should assume that the dataset will include a total of 270 blood biospecimens (9 blood biospecimens from each of 30 participants). Proposers may assume that they will have access to the human blood biospecimens but should clearly delineate proposed tasking and associated costs for processing the blood biospecimens vs. analyzing -omics data. Proposers shall develop a milestone-driven work plan, incorporating metrics and deliverables into the 17-month period of performance. Proposals should include measurement methodology (devices, collection approach, etc.) for achieving the Somnus study goals according to the timeline shown in Fig. 1. Periodic milestones will direct efforts to meet the final goal of the Somnus study. A minimum set of these milestones are described below in the context of key tasks associated with Somnus goals. Proposals should describe any additional milestones required to achieve the study goals and the milestones described below. For example, additional milestones may include a timeframe for completing multiomic analysis of animal blood and fecal biospecimens to achieve data analysis goals before or by the end of the Base Period. Throughout this document, �multiomic analysis� refers to chemical and genomic methods of processing the collected biospecimens, and �data analysis� refers to computational methods of identification, characterization, and interpretation of multiomic raw data outputs. Option 2 is updated as follows: Option 2: Correlation between human and animal blood biomarkers of fatigue (13 MAC - 17 MAC): Using a dataset of human blood biospecimens collected prior to and throughout periods of acute sleep deprivation (to be provided by the government), along with the animal dataset collected in the Base Period, assess correspondence of molecular markers between the human and animal datasets with regard to their role in sleep/wake states and cognitive function in the context of acute sleep deprivation and recovery. The Option must include, at least, the following key milestones: Month 17: Using animal data collected in Base Period Task 1, along with human blood biospecimens provided by DARPA, identify similarities and differences between humans and animals in relative concentrations of circulating biomolecules associated with sleep-wake states prior to and following acute sleep deprivation, as well as following recovery sleep. Measure transcript relative abundance and calculate fold change (? 2) in expression mRNA expression levels in sleep deprived compared to non-sleep deprived individuals. Analyze specific immune related transcripts. Identify biomolecules, perform functional interpretation using GO enrichment algorithms, and establish network mapping using pathway databases such as KEGG, Reactome, or Ingenuity Pathway. Original Posting: Special Notice DARPA-SN-23-40 Defense Advanced Research Projects Agency (DARPA) / Biological Technologies Office (BTO) Research Opportunity: Somnus I. INTRODUCTION This announcement describes a research thrust, entitled Somnus, that will focus on the identification of molecules and mechanisms of host interactions with the gut microbiome that are associated with the restorative effect of sleep on cognitive performance. This solicitation is released under the current DARPA BTO Office Wide Broad Agency Announcement (BAA), HR001122S0034, entitled �Biological Technologies,� which can be found at the URL below: https://sam.gov/opp/4f70483c0b4b49aeac299342a36af04d/view This special notice is soliciting proposal abstracts and full proposals to HR001122S0034.

TOPIC DESCRIPTION DARPA is soliciting proposals for research aimed at identifying molecules and mechanisms of host interactions with the gut microbiome that are associated with the restorative effect of sleep on cognitive performance. To achieve this goal, funded studies will utilize an animal model of acute sleep deprivation and recovery, along with a variety of approaches to collect biospecimens for measurement and analysis. Proposals should include descriptions of optional tasks, that, if exercised, will include analysis of previously collected (i.e., banked) blood biospecimens obtained from humans undergoing an acute sleep deprivation protocol and comparing results with animal data collected during the Base Period. Overview � Somnus: Insufficient sleep is highly prevalent in the military and has multiple causes ranging from environmental factors to disease processes. According to a recent DoD study, 64% of US service members reported less than seven hours of sleep per night, compared to 28-37% of adults in civilian population. Irrespective of its etiology, sleep loss has negative effects on health and performance that are poorly addressed by existing therapeutic interventions. Acute sleep loss has been found to result in cognitive and social dysfunction, as well as dysregulation of molecular pathways underlying immune and metabolic function. While negative effects of acute loss may be restored by follow-on recovery sleep, achieving effective recovery sleep may be stymied by 2 suboptimal environmental or disease-related conditions, leading to chronic sleep loss. The deleterious effects of chronic sleep loss are systemic and include metabolic dysregulation (insulin resistance, diabetes, and obesity), immune dysfunction (increased risk of infection, neurodegeneration, and autoimmune diseases) and neuropsychiatric disorders (PTSD, depression, and increased risk of suicide). Furthermore, sleep restriction reduces the ability to execute complex cognitive tasks, effective communication, rapid decision making, and maintenance of vigilance and alertness required to carry out assigned duties. The propensity to sleep and the subjective experience of sleepiness accumulate with increased time spent awake, but the biological mechanisms regulating this drive to sleep, or �sleep pressure,� have not been characterized. Recent studies have identified various changes in gut microbiota associated with sleep deprivation and/ or insomnia in humans, as well as in animal models. Evidence suggests that the gut microbiomes of insomnia patients compared to healthy controls are characterized by lower microbial richness and diversity, as well as depletion of anaerobes and short-chain fatty acid (SCFA)-producing bacteria. Additionally, gut bacterial metabolites and components of the bacterial cell wall have been shown to serve in sleep signaling through peripheral pathways, such as the hepatoportal vein and the vagus nerve. Notably, however, these observed associations have not been tied to changes in functional outcome measures associated with cognitive function following sleep deprivation. Thus, it is unknown whether such observed changes in the gut ecological environment lead to deleterious effects of sleep deprivation on health and performance, or whether they are involved in compensatory mechanisms to recover physiological function following sleep deprivation. Moreover, while studies have suggested that modulating the gut microbiome via mechanisms such as administration of prebiotics, butyrate (a gut bacterial metabolite) or lipopolysaccharide (a bacterial cell wall component) can modulate sleep/wake states in animal models, the underlying mechanisms have not been fully elucidated, and the impacts of these interventions on health and functional performance following sleep deprivation have not yet been explored. Somnus seeks to identify molecules and mechanisms of host interactions with the gut microbiome that are associated with the restorative effect of sleep on cognitive performance in an animal model. If successful, the study may pursue additional efforts to identify similarities and differences between humans and animals in relative concentrations of circulating biomolecules associated with sleep pressure and cognitive outcomes across acute sleep deprivation and recovery. Objective: DARPA is interested in revolutionary research ideas to assess and modulate the impact of gut microbiota on sleep-wake states and cognitive function across acute sleep deprivation and recovery according to the following 17-month structure. The Somnus study is divided into a base period of performance of 13 months and an option period of 4 months as described below: Base Period: DARPA seeks to identify gut microbiota and downstream biomolecules (e.g., metabolites, lipids, peptides, nucleic acids, etc.) associated with acute sleep deprivation and recovery. Additionally, DARPA is interested in characterizing differences in gut microbiota and associated biomolecules � including circulating molecules detectable in blood samples � corresponding to inter-individual variability in the physiological, behavioral, and cognitive effects of sleep pressure as it fluctuates between deprived and recovered states. At the conclusion of the Base Period effort, performers will deliver a list of identified molecules that could be exploited to modulate physiological underpinnings of the cognitive response to changes in sleep pressure. Options: There are two separate option tasks that, if DARPA elects to proceed with both, may be executed in parallel with one another. Option 1: Should the first option task be executed, performers will conduct extended, system-level analyses of datasets obtained in the Base Period, with the goal of identifying putative molecular/biochemical pathways associated with host-microbiome interaction in the gut and resultant molecules in the blood that correspond to sleep pressure and its effects on cognitive function. Option 2: Should the second option task be executed, the government will provide a previously collected dataset at the start of this task that includes blood samples and cognitive performance measures collected prior to and following a period of acute sleep deprivation across a cohort of approximately thirty (30) participants. The goal of this option is to verify that molecules, or their homologs, identified during the Base Period of Somnus, correspond to changes in sleep pressure in humans. Anticipated Structure: The Somnus study duration is 17 months. The period of performance (PoP) includes obtaining local Institutional Animal Care and Use Committee (IACUC) and U.S. Army Medical Research and Development Command Animal Care and Use Review Office (ACURO) approvals as well as successfully identifying molecules and mechanisms of host interactions with the gut microbiome that are associated with the restorative effect of sleep on cognitive performance in an animal model. Should Option 2 be exercised, the PoP also includes obtaining local Institutional Review Board (IRB) and U.S. Army Medical Research and Development Command Office of Human Research Oversight (OHRO) approvals to analyze a previously collected dataset of biospecimens provided by the government, in order to identify circulating biomolecules associated with sleep pressure and cognitive function prior to and following acute sleep deprivation, if required. Proposers shall develop a milestone-driven work plan, incorporating metrics and deliverables into the 17-month period of performance. Proposals should include measurement methodology (devices, collection approach, etc.) for achieving the Somnus study goals according to the timeline shown in Fig. 1. Periodic milestones will direct efforts to meet the final goal of the Somnus study. A minimum set of these milestones are described below in the context of key tasks associated with Somnus goals. Proposals should describe any additional milestones required to achieve the study goals and the milestones described below. For example, additional milestones may include a timeframe for completing multiomic analysis of blood and fecal biospecimens to achieve data analysis goals before or by the end of the Base Period. Throughout this document, �multiomic analysis� refers to chemical and genomic methods of processing the collected biospecimens, and �data analysis� refers to computational methods of identification, characterization, and interpretation of multiomic raw data outputs. Fig. 1. Somnus study timeline. Base Period (13 Months): Identify gut microbiota, associated biological molecules, and molecular pathways associated with sleep pressure and cognitive function in the context of acute sleep deprivation and recovery in an animal model. The Base Period will consist of two main tasks. Task 1 (1 MAC � 13 MAC): Obtain required protocol approvals (IACUC & ACURO) for all animal studies to be conducted during the Base Period. Animal use protocols must describe how the performer plans to study acute sleep deprivation and restorative sleep in both optimal and suboptimal (e.g., noisy or stressful) conditions in an animal model. Acquire biospecimens and other physiological measures across sleep deprived and non-sleep deprived states in an animal model to identify changes in the relative abundance and/or activity of gut microbial species, as well as increases or decreases in circulating molecules attributable to gut microbiota in response to changes in sleep pressure (i.e., recovery from fatigue due to sleep restriction) and resulting cognitive function. Task 1 involves data collection from animal models only; any proposed efforts to collect human data will be considered out of scope. To reduce potential gaps in data collection between the Base and Option Periods, Task 1 involves submission of human use protocols in preparation for potential execution of Option 2, which includes analysis of a government-provided human dataset (see Option 2 description below for additional detail). Task 1 must include, at least, the following milestones: Month 1: Submit animal use protocol packages for IACUC review and approval. Month 2: Upon receipt of IACUC approval, submit animal use protocol packages for ACURO review and approval. Month 4: Upon receipt of ACURO approval, begin collection of biospecimens and other physiological measures across sleep deprived and non-sleep deprived states. Month 8: Acquire biospecimens from the gut microbiome and blood within-subjects across periods of acute sleep deprivation and recovery in an animal model. o Obtain physiological measures associated with changes in sleep pressure over the course of acute sleep deprivation. o Quantify physiological correlates of recovery sleep in response to acute sleep deprivation. o Assess behavioral performance on cognitive tasks across baseline and acute sleep deprivation conditions, as well as following recovery sleep. o Collect biospecimens from animals across baseline, sleep deprivation, and recovery sleep conditions, including whole blood, fecal samples, or comparable specimens. o Collect additional biospecimens from animals after recovery sleep including luminal fluid, intestinal tissue, or comparable specimens. Month 10: In preparation for potential execution of Option 2, submit IRB packages for research protocols involving analysis of blood biomarkers in human datasets furnished by the government. Month 11: Upon receipt of IRB approval, submit human use protocol packages for OHRO review and approval for potential Option 2 efforts involving analysis of blood biomarkers in human datasets furnished by the government. Month 13: Finalize test plan for Option 2 to include planned analytical approaches and pipeline. Task 2 (7 MAC - 13 MAC): Perform multiomic analysis of biospecimens (transcriptomics/metatranscriptomics, metagenomics, proteomics, and/or metabolomics) to identify molecules that arise from interactions between the host and microbiome and correlate with changes in sleep pressure and its effects on cognitive function across acute sleep deprivation and recovery. Task 2 must include, at least, the following milestones: Month 10: Complete acquisition of biospecimens including collection of additional biological specimens/tissues during baseline, sleep deprivation, and recovery. o In additional cohorts of animals, obtain intestinal tissue, luminal fluid, or comparable specimens after baseline sleep and after sleep deprivation. o Obtain physiological measures associated with changes in sleep pressure due to sleep deprivation, and assess behavioral performance on cognitive tasks across acute sleep deprivation and recovery. Month 13: Analyze multiomic data from blood and fecal biospecimens from within-subjects cohorts (transcriptomics/metatranscriptomics, metagenomics, proteomics, and/or metabolomics) to identify molecules that arise from the gut microbiome/host interactions and correlate with changes in sleep pressure and its effect on cognitive function across acute sleep deprivation and following recovery sleep. o Complete multiomic analyses for all biospecimens. o From the multiomic dataset obtained from blood and feces biospecimens, complete the following data analyses to address changes in sleep pressure across acute sleep deprivation and recovery periods, as well as inter-individual variability in the effect of sleep pressure on cognitive task performance: . Calculate transcript relative abundance and fold change (= 2) in mRNA expression levels. . Assess phylogenetic diversity of the gut microbiome using Alpha diversity measures (Shannon H� index of diversity, Simpson index of dominance, or similar) and Beta diversity (using Bray-Curtis dissimilarity measures). Determine relative abundance (% of the total sequences) of the bacterial genus level, and calculate fold difference. . Use Gene Ontology (GO) enrichment analysis to determine tissue-specific or ubiquitous gene functions, and to generate functional organized pathways/networks. . Identify microbiome derived biomolecules, perform functional interpretation using GO enrichment algorithms, and establish network mapping using pathway databases such as KEGG, Reactome, Ingenuity Pathway. Progress towards the stated goals will be assessed throughout the Base Period, with funding for Options 1 and 2 described below dependent on both funding availability and performance towards the Base Period milestones. Option 2 is also dependent on the government�s ability to provide multiomic datasets from human blood biospecimens obtained across varying degrees of sleep deprivation. Option 1: Multiomic data analysis to identify molecular pathways from the gut to the blood (13 MAC � 17 MAC): Using datasets generated in the Base Period � including additional biospecimens, such as luminal fluid and intestinal tissues, to augment datasets from blood and feces � perform systems-level analyses to identify correlated molecular events probabilistically associated with blood biomarkers of sleep pressure and its effects on cognitive task performance. Month 17: Complete analysis of multiomic datasets from additional biospecimens (e.g., intestinal tissue, luminal fluid, etc.) to validate correlations derived from analysis of blood and fecal biospecimens. Identify molecules that arise from interactions between the host and microbiome and correlate with changes in sleep pressure and its effect on cognitive function across acute sleep deprivation and recovery. Option 2: Correlation between human and animal blood biomarkers of fatigue (13 MAC - 17 MAC): Using a dataset of human blood samples collected prior to and throughout periods of acute sleep deprivation (to be provided by the government), along with the animal dataset collected in the Base Period, assess correspondence of molecular markers between the human and animal datasets with regard to their role in sleep/wake states and cognitive function in the context of acute sleep deprivation and recovery. The Option must include, at least, the following key milestones: Month 17: Using animal data collected in Base Period Task 1, along with human blood samples provided by DARPA, identify similarities and differences between humans and animals in relative concentrations of circulating biomolecules associated with sleep-wake states prior to and following acute sleep deprivation, as well as following recovery sleep. o Measure transcript relative abundance and calculate fold change (= 2) in expression mRNA expression levels in sleep deprived compared to non-sleep deprived individuals. Analyze specific immune related transcripts. o Identify biomolecules, perform functional interpretation using GO enrichment algorithms, and establish network mapping using pathway databases such as KEGG, Reactome, or Ingenuity Pathway. Ethical, Legal, and Societal Implications (ELSI): DARPA maintains its commitment to ensuring that efforts funded under this Special Notice adhere to ethical and legal regulations currently in place for Federal and DoD-funded research. Somnus developments will be discussed with a panel of expert external advisors with expertise in bioethical issues that may emerge as a consequence of advances in biomedical science and technology, including those that may occur beyond the scope of this Special Notice, such as modulation of the microbiome and/or sleep schedules in humans. Proposers should plan to support ELSI activities with DARPA, including semi-annual teleconference calls with an ELSI group that DARPA will engage. Somnus performers will need to consider the feedback from the ELSI group regarding their research activities, and to this end, ELSI outcomes will be reported regularly to DARPA. III. PROPOSAL ABSTRACT SUBMISSION For this special notice, DARPA strongly encourages that abstracts be submitted before any proposals. Please note that the deadlines for Somnus study abstract and proposal submissions are different from the general abstract and proposal deadlines that are listed in HR001122S0034.
