MIATA Version 1.0 MIATA version 1.0 evolved from MIATA version 0.0, and was further changed during the second public consultation period. This version is listed here for demonstration purposes. It should not be used for MIATA-compliant reporting.

MIATA Version 0.0 is being updated to Version 1.0. The initial modules have been moved to the archive.
Here you find the updated MIATA modules, version 1.0, based on the comments from the public consultation period and their discussion at the first consensus workshop in March 2010, and three follow-up webinars in May 2010, following the concept illustrated in the figure below.

MIATA Module 1, Version 1.0


31.03.2010 Proposal for Module 1 of MIATA Version 1.0 (based on Consensus workshop and comments from the public consultation period)

Purpose: Reporting framework for publications of human immune monitoring T cell studies


Module 1: Minimal Information on the sample


Proposal for Version 1.0, Module 1A: Donor:


Required to report:


It should not be required to provide any information on the donor.


Optional:


Investigators might want to provide specific details whenever there is a strong specific scientific rationale for doing so to enable better understanding of the T cell assay results. In cases donor information is provided there was strong agreement in the comments from the public consultation period that it might be generally interesting to report (i) age, (ii) gender, (iii) ethnical background and (iv) diagnosis of the studied population as all these “conditions” have been shown to generally influence immune reactivity of tested donors. This can be considered for reporting into a database.


Exclude:


Too detailed information that might allow trailing back to an individual patient.


Specific comments to Module 1A:


The necessity to provide additional details on the donors critically depends on the specific study setting. Information on the donors would primarily be needed to understand the study itself but is not needed to understand how the assay was performed.


Proposal for Version 1.0, Module 1B: Source

Required to report:


    • the source of the cell material and collection methodology (e.g. Heparin blood vs. lymph node biopsy vs. tumor infiltrating lymphocytes),


    • mean time laps between drawing and processing (e.g. <8h, <24h, not known),


    • method for cell processing (e.g. density gradient centrifugation).


Optional:

Investigators might want to provide an extended list of details on the source and method for cell processing as well as equipment and reagents used for preparing the cell material for freezing or further testing whenever there is a strong specific scientific rationale for doing so to enable better understanding of the experiment.

Added Reference: 2A


Specific comments to Module 1B:


It has been clearly shown in the literature that (i) collection methodology, (ii) time laps between drawing and storage, (iii) method for cell processing can critically influence T cell function.


Proposal for Version 1.0, Module 1C: Cryopreservation and Storage

Required to report:


    • use fresh or frozen material


    • In case of cryopreservation, basic information on devices, process and media used for freezing and thawing cell material


    • temperature cell material was stored at


Optional:

Investigators might want to provide an extended list of details on cryopreservation and storage whenever a strong scientific rationale exists for doing so to enable better understanding of the T cell assay results. In cases more information is provided it would be of great interest to know (i) the mean time lapse between freezing and testing in time ranges (e.g. 3 years of storage time before testing) and details on the conditions for storage (e.g. -80°C vs. liquid nitrogen and/or transport to central lab).


Specific comments to module 1C:


All measures taken to prepare cells for storage (=freezing), to store cells and to prepare cells for testing after storage (=thawing) should finally support cell viability and immunologic function. It has been clearly shown in the literature that (i) cryopreservation medium, (ii) methodology for freezing and thawing, and (iii) conditions for storage and transport can critically influence T cell functions.


Proposal for Version 1.0, Module 1D: Quality of cell material:

Required to report:


    • mean recovery and viability of cell material,


    • method to determine the cell recovery and viability


Optional:

Investigators might want to provide an expanded list of details on the quality control of the cell material that was tested whenever a strong specific scientific rationale exists for doing so to enable better understanding of the experiment. In cases when more information is provided there was strong agreement in the comments from the public consultation period that it would be of great interest to know (i) specific cut-offs for recovery and viability (if applicable), (ii) how material was treated that did not reach the cut-off and (iii) the mean time laps at which viability was tested relative to the time of thawing and the experiment.


Specific comments to module 1D:


Quality of cell material considered as being very important and most critical aspect of whole module 1 (“Characterization of important starting material of immunoassay”).

Comments for discussion:

 

Before version 2 is be prepared for publication we should prepare MIATA-conform example reports for ELISPOT, HLA-peptide MULTIMER staining and cytokine flow cytometry. These examples will show if preparation of a publication within the MIATA framework will be feasible/appropriate and make sure that we do not put inappropriate burden of work to scientists.

We should emphasize to the community that it might take some extra time to prepare the first publication in conformity to MIATA. Once a template has been generated for a given lab and assay, the preparation of follow-up publications will be much less time consuming.

When publishing version 2 of MIATA we have to make sure that appropriate wording is used. It should be clear that MIATA is only there for the report of generated data and is not a template for how a lab should perform its studies. Extra care has to be taken so that scientific progress is not hindered and that publications from labs not using specific standards or grades of validation are not inappropriately censored.

Before version 2 of MIATA is prepared for publication we should reach a consensus on how to position MIATA towards other MI projects with overlap (e.g. REMARK, MyFloCyt and others). The value of MIATA should become very clear, redundancy should be avoided whenever possible and settings that would suite better to other existing MI projects should be listed.

18Steven Smithno commentI assume that if the assay used whole blood (whether diluted or not) would be covered in the assay or sample processing descriptions. For these, information such as anti-coagulants used are important as different ones can affect some assays as they're still present in the assay. Êtime between drawing and processing (which might be dilution of blood in media or aliquoting into tubes) would be desirable. As time to processing has been shown to affect responses I would go further than asking for rough estimates (e.g. <4 hrs or <8 hrs) and ask that times of drawing and processing are recorded for each sample then a mean/median processing time for the sample cohort reportedno commentno comment
19John Huralno commentÊI think the statement Òmean time lapse between drawing and processingÓ is a bit too vague. That could be interpreted as time between blood draw andÊbeginningÊprocessing rather than when the specimen goes into the freezer. Lapse is misspelled as ÒlapsÓ in 1B. the actual processing time is important as well. In other words, the time from opening the blood draw tubes to freezing the cells. It generally takes 2 to 2.5 hours. If we see actual processing times of 3 or more hours it often correlates with reduced viability and recoverythe amount of time at Ê-80 (or -70) before moving to liquid nitrogen is also important. my impression of the current environment is that these are things readers will want to know. ÊThis would require a bit more detail under both 1B and 1C. For example, under 1C, Òtemperature sample was stored atÓ is also too vague for the reasons I mentioned above.For 1D, it may be difficult to require recovery data. Determining recovery is only possible if a particular attention is paid to cell count and aliquotting during processing. This is not standard practice.
20Venky Ramakrishnaadd here "medication history" for normal volunteer blood source, fasting conditions to minimize chylomicronsNote expiration dates on green top tubes and fill volumes. The latter is important for maintaining heparin to blood ratios and anti-coagulant properties.

Regarding Optional information, we usually do not find gender-related differences. may be useful to indicate pregnancy status in the optional infoimportant in the Optional information to include the "mean time lapse between starting of sample processing and starting of cryopreservationthere appears to be some redundancy between the Required information "temparature storage" and the Optional information (details conditions: -80¼C, liquid nitrogen...). To avoid confusion, we consider that in Required information, not only the temperature but also whether storage was -80¼C orÊ-150¼C freezers or liquid nitrogen should be stated, as those are intimatly linked to temperature. Then, in the Optional information it could perhaps be added whether the samples were in the liquid or vapour phase of liquid nitrogen, if applicablespecific cut-offs for viability should be Required information, not just optional

31Gerold Schuler and Stefanie Grossno commentWhat do you mean with "pretested", is the media/serum pretested right before each assay (which is the only pretesting-information that would make sense to me, but usually this requires a lot of additional work and is not performed in most labs), or only each batch of the single reagents or each bottle of the complete medium. If the assay was not performed for the first time in the lab, then the medium/serum is allways pretested, because it was used in an other assay. Therefore the information on media-pretesting should not be required. It would be more important to know wether media were allways prepared fresh or how long the average shelf life was.no commentno comment

As a company that provides tailored reagents for such assays we know that there is currently limited consensus in the field which details are crucial to enable reproducibility of an assay. As a consequence the sole request for details might be inappropriate since the nature and level of details provided will vary tremendously depending on the subjectively biased opinion of the investigator Êperforming the assay.

43Staffan Paulieno commentno commentwe agree with the recent comment by Holger Wenschuh (June 3) that it may be helpful to more specifically indicate what should be reported in terms of reagents, material and procedure since there is no general consensus what is here important. For instance, and given the very significant influence that the choice and treatment of plates may have for the outcome of an ELISpot assay, there may be a need not only to include information about the type and manufacturer of the plates used (e.g. if PVDF, nitrocellulose or other membrane) but, if using PVDF plates (normally recommended), also state whether they were preactivated or not with ethanol and how this pretreatment was performed. Another issue that is more related to the cells and a potential problem with all cellular assays, is the quality of the substances to which the cells are exposed. In addition to the pretesting of serum and medium that is suggested in the harmonization guidelines, one should here consider the risk for endotoxin contamination of e.g. the antigens used for antigen challenge (particularly when using recombinant antigen) as well as the capture antibodies used in the ELISpot assayno comment

I would also require the information on what aspects of data evaluation were set globally for the reported study and what aspects were sample or assay individual (e.g., patient individual gates
19John Huralno commentÊIt seems that require ÒsampleÓ elispot data is going a bit far and, of course, would only be a sample. So the usefulness could be questioned. For flow experiments provision of sample plots, namely gating strategy, may be good, but again, it is just a sample, and likely the best sample the author had available rather than a ÒrepresentativeÓ sample
24Carlota Dobanono commentn the required information, we would also add an "illustration of the gating strategy" (which is different to a "detailed explanation", as included in optional)

29Lisa Butterfieldno commentI agree with those suggesting that the gating strategy should be required. If simple, it could be included in Materials and Methods text, but when complex, it could be shown/diagramed as part of one of the examples of raw data. Much can be learned about the approach used, and the cells used in a few dot plot panels showing gating strategies.

33Holden Maeckerno commentÊIn addition to representative raw data, I think a summary of the gating strategy should be required.Ê This could be as simple as:Ê "Spot counting was performed using the instrument default settings (for ELISPOT)" or "Samples were gated on CD3+CD4+ viable lymphocytes (for ICS)".Ê For flow cytometry experiments, an actual figure of the gating strategy should be highly recommended, and could be supplied as a supplemental figure.
34Ronald RookeIn the optional section, it is mentioned Òinformation on the routine QC proceduresÓ. This should be expanded to all sections (or limited to section 5 ?) as QC procedures are not limited to machines and softwaresIn the optional section, the vocabulary used seems limited to flow cytometry. Expanding it to ELIspot acquisition conditions may help in data interpretation (spot size acquired, thresholds applied, etc.
35Guido FerrariIt seems to me that 3 should be "Data acquisition": that include what already mentioned, but I am missing whether we require to provide information on how the instruments are QCd both cytometers and ELISpot readers. In case of flow cytometry-based assay, the instrument settings used to acquire data should be provided as wellModule 4 should be more about "Data analysis and accessibility". So, 3B should be really 4. I don't agree on leaving detailed explanation on gating strategy as optional, this should be mandatory. This should also required to provide information on whether or not any transformation of the results was applied, though this can be judged by the axises, it may be still important to have a comment directly from the author. So, mainly redistributing info among modules and a couple of adjustments in the requirement to fit a better separation of topics.
36Kimberly Shafer-Weaverno commentÊI agree with Holden Maecker that in Module 3B that the acquisition parameters should be specified and that a representation of the gating parameters be provided.

47Marij weltersno commentAcquisition strategy: (better mentioned as acquisition and analysis strategy ?) For flow cytometry-based assays it should be required to display the complete set of facs plots (at least in supplemental figures) of a positive (and optionally negative) sample to show the gating strategy.This will also remove the optional part: Òin case an uncommon strategy was appliedÓ since it is still not known what strategy is the best. Optional: this includes also instrument settings of ELISPOT readers ?

9Guido FerrariThe proposed parameters that are required for each module are fine with me.ÊI don't have any other comment. Well done.
10Bart RoepYour report seems very acceptable, feasible and logical to me. Good job.
12Tania KollgaardWe have been through your Miata version 1 - had nothing to add at all! We find it "very mature" - and very nice as a framework
13Tina DalgaardI have spent a little time on the MIATA website and I find it very useful. It is a good inspiration even for us who work in veterinary immunology. In general, I am very pleased but when first reading the modules - I missed some of the flow cytometry issues - until I realized that it is covered by MIFlowCyt. MIATA is a very nice piece of work, so far.
14Michele Miao and Nughus NicolayWe find the report clear and acceptable
15ÊMarcella Sarzotti-KelsoeCurrent Miata Modules and the consensus so far. I agree with most of them. My congratulations to the MIATA team for their great efforts
21Dolores SchendelThe MIATA project is very important for raising the visibility of the immune monitoring field and demonstrating how coordinated efforts through the exchange of information and best practices will help us all to move immunotherapy forward. By pooling our scientific and technological expertise in MIATA, we work for the good of our scientific field and provide a dynamic platform to improve the tools of immune monitoring

I would like to see more of a purpose in the opening paragraph. It currently states that the purpose is the reporting framework for publications of human immune monitoring T cell studies. What is missing is why this is important or why do we want this framework. I think it should state that these reporting frameworks will then allow for others to compare results from different therapeutics and decide if they are comparing apples to apples or apples to oranges. It also gives details so that others can reproduce the assays. It also lets others see differences in the assays that they are performing which could lead to potentially different results. I think there needs to be this purpose so that people see these guidelines in a positive light not that anyone is trying to point fingers about the way assays are being run or data is being interpreted.
31Gerold Schuler and Stefanie GrossWe are really happy with the new Version of the MIATA guidelines, really great job! The new Version1 of the MIATA guidelines should now be applicable for every lab dealing with t cells
32Michael KalosVersion 1 is a substantive improvement on version 0.ÊÊ Comments from the community during the initial consultation phase and the workshops have significantly streamlined and strengthened these guidelines.Ê No significant criticism from me on these modules.Ê I look forward to further refinement of the MIATA guidelines through this consultation process and the upcoming FOCIS workshop and to begin to see broader implementation of these guidelines in publications
35Guido FerrariI had the opportunity to take a look at the document and it looks fine to me. A lot of comments, all very appropriate have been posted, and I think we are in good shape there
37Holger WenschuhIn addition, I think that such details compiled by the experts in the field would clearly add to the value of the MIATA endeavour
38Cedrik BrittenFrom many discussions on the content of MIATA modules over the last 18 months, I understood that a significant fraction of expert investigators for good reasons were asking for more detailed information in the ÒrequiredÓ part of MIATA on one hand. On the other hand a large fraction of investigators were strongly against expanding the framework to a point where reporting of assay results would become Òtoo much of a burdenÓ. ÊAt the beginning of the project I was in strong favor for the expansion of MIATA to capture results on all (!) critical aspects of T cell assays. In the last months I have changed my position and I am now more in favor of a ÒleanerÓ version of MIATA as acceptability and feasibility should be considered as being equally important for the success of MIATA as the quest to generate a framework capturing comprehensive explanations on every single detail of T cell assays. Whenever adding new parts to the required part will have the likelihood to reduce the chance that MIATA will become broadly acceptable and easily applicable, I strongly recommend adding any new aspects to the ÒoptionalÓ part. Many expert labs will probably decide to provide information on the ÒoptionalÓ part in the future. Expanding the required part might lead to opposition against MIATA that might prevent the adoption rate in the scientific community
39Henrik PedersenIn general, we think as many comments and specifications should be included as possible. The time going into the experiments or clinical trials is so much more than the time it takes to specify reagents, protocols etc, wherefore details should be given. We think. Generally: For each of the steps in each of the modules, an appropriately detailed protocol, including specification of all reagents and materials used, should be prepared that would allow others to understand and repeat the analysis and reach the same conclusion. It should be stated how many times the entire experiment (modules 1-5, or at least module 2-5) has been independently performed on each sample (e.g. duplicate analysis).
40Paola NisticoThe research community agrees that the T cell immune monitoring represents a pillar for further studies of mechanisms, enabling the understanding of the immune response and the possibility of manipulating it in disease. The efforts of the MIATA proposal to establish minimal information of T cell immune monitoring to include in scientific publication, are so relevant in the field that all the investigators should contribute with constructive suggestion.
41Shane LarsonI will say that the resources on the MIATA website have been extremely helpful- from blood collection/processing to assay development/qualification and even statistics. Even though I read through all of the papers after the bulk of our assay development it mirrored (in some papers, almost exactly) how we approached it here at Genocea, which gave us confidence inÊthe power of our assays
43Staffan PaulieIn agreement with many earlier comments, I think the MIATA guidelines will become a very useful tool and framework that will help both the researcher when planning and designing a study and the reader when evaluating reported data
44Adrian BotThe modules look great and the most relevant aspects that will finally determine the performance of T cell immune assays have been adequately addressed. The checklist also appears to be balanced in terms of the amount of requested information which should make it feasible to implement MIATA easily.ÊAnother issue that I would like to raise is whether a refinement of the assays is needed to capture more relevantly the appropriate immune effector cells as needed? Unfortunately, the correlation between the "immune response" as measured by more robust, standardized methods and clinical outcome respectively, have been less than optimal. It is clear that we (as a field) do not understand entirely what we need to monitor for. This is further complicated by the fact that distinct immune interventions may deploy different mechanisms of action. Perhaps emerging investigational therapies that afford a higher rate of clinical response would prove essential to elucidate what exactly we need to monitor in man? This question seems as important to me as the Êquest for structuring reports from commonly used T cell immune monitoring assays.
45Jo CoxThe contributors to MIATA are to be congratulated on the guidelines which are comprehensive and far reaching in scope. ÊImplementation will eventually lead to improved reporting of immunology data and allow cross-trial comparisons. Many excellent comments have been already posted and there is not much new to be contributed. My biggest concern remains how will these recommendations be implemented? Experienced reviewers will be able to recommend that authors revise manuscripts according to the MIATA guidelines but so far few journals have started imposing the new guidelines.Ê Open access journals should be able to implement the MIATA guidelines reasonably easily since they already insist on documentation such as clinical protocols and CONSORT diagrams supplied as supplementary information or included in the manuscript.Ê The MIATA workshop will need to seriously address how non-specialist journals will be able to monitor compliance.ÊÊ Can a check-list be developed with the ÔrequiredÕ and ÔoptionalÕ information needed which authors would be asked to submit as supplementary information.Ê A check list would be easy to implement and review. A Êcheck list would allow data mining across studies
46Chris TaylorI am enormously encouraged by the continued enthusiasm for the further development of MIATA and by the obviously broad participation from within the relevant community. Certainly the project fills a gap in the market that would otherwise remain. I understand that comments continue to pour in both through the excellent web site and the series of meetings. Good communication with the ultimate consumers of your product is the life blood of a standardisation project. This follows best practice in standards development and I applaud your continued dedication to doing things 'the right way'. As for MIATA itself: in general, I am pleased to see that through the use of fairly general phrases you encourage debate -- to be too concise in a draft specification can discourage participation, because the project might appear to be finished, whereas the style of the current draft makes clear that there is still room for debate. The corollary is of course that when the content is more settled, more specific detail would be better (especially in your optional sections) Ê-- certainly from the point of view of an implementer of such guidelines it can be difficult to turn general statements into data entry fields in software or a database (MIAME offers a salutory lesson there -- a recent paper from GEO expressd their regret that while they would like to be able to confirm MIAME compliance in submissions to that database, they feel unable to properly verify compliance as MIAME is couched in such general terms). Additionally, once you reach the final validation stage, specificity will reduce the room for misinterpretation by reviewers and users, ensuring that you get the comments you need to be sure you got it right. I believe you have pitched MIATA at an appropriate level; certainly it is broadly comparable to documents such as MIAPE and MIFlowCyt in neither asking for excessive detail nor too little; by this I mean that the completion of a MIATA-compliant report would not seem to be particularly onerous as the guidelines currently stand. (Incidentally, where flow cytometry is employed in a T cell assay will you refer people to MIFlowCyt?) Where you overlap with equivalent guidelines you seem to have settled on a similar level of Êdetail, which I see as validation (for example, to be in broad agreement on such things as the desciption of a sample). I see little to criticise excepting a few forgiveable typos. So to sum up, I would like to congratulate you and your collaborators on your continued progress with MIATA, on your efforts to engage the community you seek to serve, and on your continued commitment as a valued member of the MIBBI project.
48Sebastian KreiterThe goal to reach a community wide consensus about a reporting framework for immune monitoring is of high importance and the progress made so far is impressive. A major issue for successful implementation will be to provide tools allowing a fast and straightforward provision of the required data (e.g. checklists).
