Acute to Chronic Pain Signatures (A2CPS) Frequently Asked Questions (FAQs)

We appreciate your interest in the NIH Common Fund Acute to Chronic Pain Signatures (A2CPS) funding opportunities. The NIH hosted a pre-application interactive Q&A webinar (NOT-RM-18-021) on September 6, 2018 for the five program FOAs:






The slides from the webinar are now available for download. In addition, this Frequently Asked Questions page is now updated to reflect questions received during the webinar.

Questions Generated from the Applicant Informational Webinar:

A2CPS General Application Questions (for RFA specific questions see lower on the page.)

Abbreviations used below:

MCC: Multisite Clinical Centers

CCC: Clinical Coordination Center

DIRC: Data Integration and Resource Center

ODGC: Omics Data Generation Centers

24. Can applicants apply to more than one RFA as a PI or as a component of a project?Can applicants submit to one or more of these RFAs and also submit investigator-initiated or other types of NIH applications?

25. Do you have some idea how many awards you are making for each RFA?

26. Is a letter of intent required?

27. Do applicants to these RFAs need to fill our human subjects sections and biohazard sections?

28. For the budget, is the dollar amount listed on the FOA direct only, or direct plus indirect?

29. How was the budget determined?

30. In terms of the 10+ proposed biomarkers, how specific do we need to be? For example, should we propose a single gene, a single measure from a single brain region, etc.?

31. Would imaging quality assessment happen at the data collection site?

32. Who will coordinate data quality for brain imaging?

MCC Specific Questions:

33.The MCC FOAs suggest that 50% of subjects should be enrolled and complete 6 months by 1 year. This means the first 6 months would need 50% enrollment. How tight is that schedule and can it be modified?

34. How would you approach realistic rates of 15% transition for some pain conditions?

35. Will a single grant with multiple centers will be funded or will individual applications be brought together to work on one surgical cohort?

36. Would NIH consider revising their sample size of 1800 subjects with a single injury type in 2 years?

37. If our cohort is smaller than 1800, then do we develop collaborations for the submission to achieve a full 1800 patient cohort before submitting, or can this happen during the planning year?

38. How do you eliminate previous drug dependence and similar confounds?

39. For the MCC, are the timepoints for data collection fixed?

40. Can we argue that more time points are necessary?

41. How similar should the types of surgery or pain events be?

42. For the MCC, there may be a tradeoff between homogeneity of the cohort and rapidity of enrollment. Which factor should be given greater weight/importance?

43. Since MCCs will be multisite, do the subcontracts need to be finalized/executed at the time of submission or can these be finalized during the planning year?

44. For the MCC, can sites decide to collect additional measures or biospecimens for questions of interest that are outside of the consortium?

45. Do all participants need to undergo brain imaging at each timepoint or can judicious selections be made for subsets of participants that will be imaged?

46. Can the brain imaging be done at multiple different sites under each MCC?

47. Since the MCC is only doing data collection, should the grant submission include planned analyses?

48. Can and how do pediatric studies fit into these funding announcements and opportunities?

49. Is there a preference to have the MCCs at different locations, or can we apply for both MCC FOAs?

50. Would proposing a clinical trial detract from the responsiveness to the MCC RFA?

51. What type of fractures and what type of thoracotomy were considered as possible acute trauma?

52. Must all the peri-operative subjects come from the MCC or can the MCC also recruit from other sites?

53. For peri-surgical pain data collection FOA, it is likely that data collection will occur at multiple sites. Do you see having one primary site & the lead site writing the proposal?Or will the proposal come from multiple PIs with each site PI being multi-PI?

54. Is breast cancer surgery an acceptable pain condition?

55. Are musculoskeletal trauma patients expected to be non-operatively managed?

56. For the musculoskeletal pain MCC, how close in time to the injury must the time 0 assessment need to be in order to be responsive to the RFA?

57. For musculoskeletal trauma, would fracture of different bones or polytrauma fit the single injury requirement?

DIRC-Specific Questions:

58. Will the DIRC extract materials from samples?

59. Doesn’t the proposal for the DIRC depend on what biomarkers are selected? How does one put together a submission for the DIRC without knowing what measures are selected?

ODGC-Specific Questions:

60. Is the microbiome included among the biomarkers?

61. Can our application to the ODGC RFA include genomics?

62. Will sample handling be performed by the ODGCs individually, or will one group be responsible for handling/tracking all samples?

63. Is it possible to outsource multi-omics assays and analysis (i.e. pay for other companies to perform the assays and analysis)?

64. For the variant genotyping, should DNA isolation be included in the ODGC budgets?
