Attachment 1
Hosted Commercial In-Life Data Collection and Management System for
NTP
Background
The National Institute of Environmental Health Sciences (NIEHS) is one of 27 Institutes and Centers of the National Institutes of Health (NIH), Department of Health and Human Services (DHHS). The mission of the NIEHS is to reduce the burden of human illness and disability by understanding how the environment influences the development and progression of human disease. The Division of the National Toxicology Program (NTP) is an interagency program whose mission is to evaluate agents of public health concern by developing and applying tools of modern toxicology and molecular biology. The NTP maintains an objective, science-based approach in dealing with critical issues in toxicology and is committed to using the best science available to prioritize, design, conduct, and interpret its studies. To that end, the NTP is continually evolving to remain at the cutting edge of scientific research and to develop and apply new technologies.
In carrying out its mission, the NTP studies the effects of environmental agents in laboratory studies, which are performed predominantly at contract laboratories and then reviewed by the NTP. The NTP requires a hosted data management system to collect data from multiple laboratories and host the data in a secure central database which the NTP scientists can access in order to review and analyze the data. The system shall use the internet to transmit the collected data securely back to the hosted database.
Purpose
The purpose of this procurement is to obtain a system that allows:
a. Access to a hosted commercial in-life data collection and management system for use by personnel of the NTP and contract laboratories carrying out NTP-directed research for one base year and nine option years.
b. User access across multiple locations.
c. Performance of statistical tests, upload capability, and ability to meet usability requirements.
d. Housing of multiple NTP study types.
I. Scope and Tasks
A. System Functionality
1. The system shall:
a. Collect data from (1) in-life studies (body weights from balances calibrated using the system, feed and water consumption using calibrated balances, clinical observations using the NTP glossary given in Appendix 1; (2) necropsy room (organ weights from calibrated balances, gross observations and tissue/site linkage using the NTP glossary given in Appendix 1; (3) fetal pathology observations using the NTP glossary given in Appendix 1; (4) reproductive studies (pairing, mating, littering, pup and litter observations); (5) histopathology observations using the NTP modified histopathology glossary given in Appendix 1; (6) calculate daily gavage volumes for individual adult animals based on the most recent individual body weight.
b. House studies using NTP MOG (Modified One Generation) and RACB (Reproductive Assessment by Continuous Breeding) reproductive toxicology protocol templates. Such RACB studies cover 1 to 2 years in the laboratory, three generations (F0 breeder generation plus F1 and F2 generations), and approximately 3000 animals per study. Templates for these two protocols are given in Appendix 2.
c. Maintain system response time for data collection to within 30 seconds throughout the study period, and system response time for modifications to the study work schedule to within 5 minutes throughout the study period, barring network or system failure and agreed-upon maintenance windows. The contractor is not responsible for network integrity and response at NTP or at labs using the system.
d. Produce reports and tables of data, both summary and individual animal data, as well as supporting real-time data collection and data review during the data collection phases of the study.
e. Produce endpoint reports containing data for all litters for each mating pair, and litter averages for each litter plus the parents’ endpoint (for example sperm count or estrous cyclicity, age and weight at attainment of developmental markers).
f. Load custom glossaries for histology, gross observations, in-life observations, fetal pathology and organ sites and associated morphologies at both the system and individual study levels.
g. Create system-wide custom endpoints for data collection, and custom calculated endpoints based on the data collected.
h. Accept retrospective data in the form of Excel spreadsheets and incorporate the data into the system.
i. Directly accept data from a networked Hamilton Thorne CASA instrument.
j. Perform the following (but not limited to) statistical tests: Cochran-Armitage trend test, Chi-square test, Fisher’s exact test, Dunn’s test, ANOVA, Kaplan-Meier analysis, stepped graph display of animal death over time.
k. Contain a process whereby the rights of each user can be restricted to particular rights for a particular study.
l. Support real-time access by multiple laboratories in such a way that the data from one laboratory is not viewable or otherwise accessible by users from another laboratory, while all sets of data are available to NTP scientists.
m. Contain a secure reporting area where users are restricted to run reports on only the data they are authorized to see. The reports shall be saved to a secure area prior to download and printing, in such a fashion that reports generated by a laboratory are visible only to members of that laboratory.

This control database shall contain data on the incidence of histological, fetal pathology and other findings in control animals from all NTP studies completed using the system, with dates of study start and termination, strain of animal, diet, route of administration and lab performing the study indicated in the database and available for filtering by the user. The Contractor shall collect this data from within the database. The contractor shall report this data for all NTP studies housed within the system. The user will view this historical control database in the system during the evaluation of findings from a particular study (using historical control data gathered within 5 years of that particular study). The system shall provide the user the choice of including or excluding the control values from the evaluated study in the historical control incidence value.
The historical control database shall be available to use as an analysis group in statistical tests.
The historical contract database shall be available in the system within the first year following data collection in the system.
IV. Statistical and Analysis Methods
A. Analysis for Reproductive and Developmental Toxicology
The system shall contain the following twelve (12) methods:
1. Guide users in using the NTP statistical decision tree: Jonckheere’s test (Jonckheere, 1954) shall be used to assess the significance of the dose-related trends and to determine whether a trend-sensitive test (Williams’ or Shirley’s test) is more appropriate for pairwise comparisons than a test that does not assume a monotonic dose-related trend (Dunnett’s or Dunn’s test). Jonckheere’s test is considered to be significant at a level of α = 0.01. Data with approximately normal distributions shall be analyzed with the parametric multiple comparison procedures of Dunnett (1955) and Williams (1971, 1972). Dunnett’s test shall be used if there is no significant trend, Williams’ test if there is a significant trend, both at α = 0.05. Data with skewed distributions shall be analyzed using the nonparametric multiple comparison methods of Shirley (1977, as modified by Williams, 1986 and Dunn, 1964). Dunn’s test shall be used if there is no significant trend, Shirley’s test if there is a significant trend, both at α = 0.05. Prior to statistical analysis, extreme values shall be identified by the outlier test of Dixon (1950) and examined by NTP personnel. Implausible values shall be eliminated from the analysis.
2. Apply multivariate analysis of variance (Morrison, 1976) to data to test for simultaneous equality of measurements across doses.
3. Compare the proportions of regular cycling females in each dosed group to the control group using the Fisher exact test (Gart et al., 1979). Because vaginal cytology data are proportions (the proportion of the observation period that an animal was in a given estrous stage), an arcsine transformation shall be used to bring the data into closer conformance with a normality assumption prior to analysis.
4. Construct tests for extended periods of estrus and diestrus based on a Markov chain model proposed by Girard and Sager (1987). For each dose group, a transition probability matrix shall be estimated for transitions among the proestrus, estrus, metestrus, and diestrus stages, with provision for extended stays within estrus and diestrus. Equality of transition matrices among dose groups and between the control group and each dosed group shall be tested using chi-square statistics.
5. Perform mixed effects logistic regression (pup is the unit of analysis, dose and survival time are predictors, litter is a random effect) with tests for trend with dose and pairwise comparisons with the control group.
6. Include different mean calculations for summarizing litter data: (a) mean of means for (e.g.) pup weights; (b) mean of all in group ignoring litter (e.g. total dead pups for a group); (c) repeated measure (for an endpoint from litters a, b, c in RACB protocol) – mixed effects ANOVA across generations; (d) developmental marker attainment, BW at birth – nested ANOVA by litter size (2 factors – dam and litters nested within dam); (e) covariate calculation of e.g. day of attainment of developmental markers using wean weight and/or litter size. The system shall calculate these statistics for each endpoint listed in the RACB and MOG protocols.
7. Use survival analysis including log-rank test or Cox’s proportional hazards model (Cox, 1972) for calculation of time to attainment of developmental markers (testes descent, vaginal opening, preputial separation) with multiple covariates, e.g. litter, animal weight at attainment of the developmental marker and animal weight at weaning.
8. The statistics module shall permit the control group in a statistical calculation to be specified by the user within the statistics report work flow.
9. Use the NTP estrous cyclicity algorithm (Appendix 4, NTP EstrousCyclicityAlgorithm.xlsx) to calculate the cycle parameters of the estrous cycle, starting from any of the four stages of the cycle, at the request of the system user.
10. Have the ability to include and exclude p-values from tables at the request of the user.
11. Permit the user to select any pair of groups within a study for pairwise statistical comparison. The pairwise comparisons shall be done using the methods described in point 6 above
12. Spearman’s Rank Order Correlation for ordinal variables, Mann-Whitney U non-parametric for tests with an upper limit cutoff, repeated measure ANOVA, test for homogeneity of variance, and the ability to transform data (to log or square root) if needed.
These twelve (12) methods shall be incorporated into the system by the end of Year 1.
B. Immunotoxicology Statistics
1. Immunotoxicology Workflow Number 1.
The system shall guide users in using the NTP statistical decision tree for immunotoxicology studies.
The data obtained using this study design shall be first tested for homogeneity of variances using the Bartlett's Chi Square Test, Bartlett, 1937. Homogeneous data shall be evaluated by a parametric one-way analysis of variance, Kruskall and Wallis, 1952. When significant differences occur, treatment groups shall be compared to vehicle control using Dunnett's t Test, Dunnett, 1955. Non-homogeneous data shall be evaluated using a non-parametric analysis of variance, Wilson, 1956. When significant differences occur, treatment groups shall be compared to vehicle control using the Wilcoxon Rank Test, Gross and Clark, 1975. Jonckheere's Test shall be used to test for dose-related trends across the vehicle and the treatment groups, Hollander and Wolfe, 1975. Student’s t Test shall be used to compare the positive control for the assay with the vehicle control, Sokal and Rohlf, 1981.
2. Immunotoxicology Workflow Number 2.
Additional tests shall include outlier analysis using Distribution box blots and Dixon’s test;
Spearman’s Rho trend test; Bartlett’s test and Levene’s test for homogeneity of variances. If data are homogeneous, then the ANOVA and Dunnett’s test are used. For nonhomogeneous data the Wilcoxon Rank test and Paired Wilcoxon Rank test are used. The Student’s t test is used for positive control data. The Jonckheere's Test shall be used to test for dose dependency among the vehicle and treatment groups.
The Immunotoxicology Workflows shall be incorporated into the system within the first six (6) months following contract award.
C. Carcinogenicity Study Statistics
1. Survival Analysis.
Statistical analyses for possible dose-related effects on survival: Cox’s (1972) method for testing two groups for equality and Tarone’s (1975) life table test to identify dose-related trends. All reported p values for the survival analyses should be two sided.
2. Calculation of Lesion Incidence.
The system shall calculate the incidence of lesions using the following method: The incidences of lesions are given as the numbers of animals affected at each site examined microscopically. When macroscopic examination is required to detect neoplasms in certain tissues before microscopic evaluation, the denominators shall consist of the number of animals that had a gross abnormality.
When neoplasms had multiple potential sites of occurrence the denominators shall consist of the number of animals on which a necropsy was performed.
3. Analysis of Neoplasm and Non-neoplastic Lesion Incidences.
The system shall use the Poly-k test (Bailer and Portier, 1988; Portier and Bailer, 1989; Piegorsch and Bailer, 1997) to assess neoplasm and non-neoplastic lesion prevalence. This test is a survival-adjusted quintal-response procedure that modifies the Cochran-Arbitrage linear trend test to take survival differences into account. More specifically, this method modifies the denominator in the quintal estimate of lesion incidence to approximate more closely the total number of animal years at risk. For analysis of a given site, each animal is assigned a risk weight. This value is one if the animal had a lesion at that site or if it survived until terminal sacrifice; if the animal died prior to terminal sacrifice and did not have a lesion at that site, its risk weight is the fraction of the entire study time that it survived, raised to the kth power.
This method yields a lesion prevalence rate that depends only upon the choice of a shape parameter for a Waybill hazard function describing cumulative lesion incidence over time (Bailer and Portier, 1988). The system shall permit the value of k to be specified, with a default value of k=3. The system shall adjust the variance of the Poly-3 statistic as recommended by Bailer and Williams (1993) to accommodate statistical variation introduced by the use of risk weights, which reflect differential mortality.
The system shall report pairwise comparisons of each dosed group with controls and a test for an overall dose-related trend. The system shall use continuity-corrected Poly-3 tests for the analysis of lesion incidence, and report one-sided p values. The system shall report the significance of lower incidences or decreasing trends in lesions as 1–p with the letter N added (e.g., p=0.99 is presented as p=0.01N).
These statistical methods shall be incorporated into the system by the end of Option 2 (Year 3).
V. Tables and Reports
A. Reproductive and Developmental Toxicology Reports
1. Test p-values shown on summary statistical reports.
Show the numeric p-value for a trend test or t-test in addition to including superscripts indicating significance in the table or report, at the discretion of the system user.
2. Cross-generation report.
This report shall contain two columns per group per endpoint. The first shall be the value for that endpoint for a given sire or dam, the second shall be the summary value for the pups (male, female or both, as the endpoint suggests) from that dam or sire. The summary values shall be calculated using the methods described in Section IV, Paragraph A, Number 6.
3. Multi-litter report.
This shall contain on one report the results of three or more litters in a generation plus a summary value for all the litters in a group combined. The format shall be litter letter in each row, dose groups across the top, with breaks for different endpoints if included on the same table. The summary values shall be calculated using the methods described in Section IV, Paragraph A, Number 6.
These reports shall be incorporated into the system by the end of Option 1 (Year 2).
B. Reproductive and Developmental Tables and Study Designs
1. Comparison of multiple groups in a study.
The system shall expand the capability for pairwise comparison of any pair of groups to statistical analysis of e.g. trend or ANOVA, or other statistical test for any set of 4 to 12 groups. This shall not be limited by generation or litter number.
2. Cross generational comparison
The system shall display a table containing summary data for a lineage of three or more generations for a given endpoint. In other words, the system shall display a report with endpoints given in rows and the columns consisting of (1) F0 values for that endpoint for each individual animal selected; (2) F1 summary values for each direct offspring of that individual; (3) F2 summary values for each second-generation offspring of that individual. The summary values shall be calculated using the methods described in Section IV, Paragraph A, Number 6.
The Reproductive and Developmental Tables and Study Designs shall be incorporated into the system by the end of Option 2 (Year 3).
VI. Additional Study Types

e. Macrophage Activation Factor Assay. Cells are incubated with B16F10 melanoma target cells at a ratio of 10:1, pulsed with 3H-thymidine, and harvested. The total 3H-thymidine counts (CPM) for each well are used to calculate the percent suppression of B16F10 proliferation.
f. Natural Killer Cell Activity: Spleen cell suspension are adjusted to obtain effector-to-target ratios of 200:1, 100:1, 50:1, 25:1, 12.5:1, and 6.25:1. The target cells, YAC-1 cells, are maintained in a stock culture and labeled with 200 mCi of 51Cr. Target cells are counted and 51Cr release compared to 100% release. The mean (± SE) percent cytotoxicity at each effector concentration is then determined for each exposure group.
2. The system shall upload data from Hypersensitivity studies containing the following endpoints within a single study (endpoint details are given in Appendix 5):
a. Primary Irritancy & Cumulative Percutaneous Toxicity Study: Animals are treated on 4 consecutive days by administration of test article or control to ear. Ear thickness at site of application is measured on Day 1 prior to treatment and 24 hours following the last treatment.
b. The percent ear swelling is calculated as the: [(mean thickness of the post treated ear / mean thickness of the pre-treated ear) X 100]-100. The percent ear swelling for the test article is compared to the percent swelling for the vehicle using a one-way analysis of variance followed by the Dunnett's t Test to determine the minimal irritating concentration, and the maximal non-irritating concentration.
c. Mouse Ear Swelling Test: This test occurs over 10 days, with treatment applied on days 1, 2, 3
(sensitization) and 8 (challenge). Ear measurements are taken on days 1, 9 and 10. The percent ear swelling is calculated as follows: [(mean thickness of both ears (24 or 48 hours post treatment) / mean thickness of both ears measured before challenge) X 100]-100.
d. Local Lymph Node Assay: Each animal is treated with one of up to eight dilutions (e.g. 100%, 50%, 25%, 10%, 5%, 2.5%, 1%, 0.5%) on Days 1, 2, and 3 of the assay. On Day 6 they receive an intravenous injection of 3H- thymidine. Data are presented as DPM (disintegrations per minute), calculated as: ([counts per minute minus the background count ]/ the efficiency of the Beta counter).
e. Immunofluorescent Staining of Lymph Node Subpopulations. Mice are treated with either test article or control on 4 consecutive days. On the fifth day mice are euthanized and the auricular lymph nodes removed, pooled and pressed into a single cell suspension. Cells are labeled in 96-well culture plates with 0.10 ml of the appropriate anti-mouse monoclonal antibodies, propidium iodide and then enumerated by flow cytometry.
The Immunotoxicology study design shall be incorporated into the system within six (6) months following contract award.

Training of subsequent more difficult schedule will generate data such as number of correct bar presses, number of incorrect bar presses, number of reinforcements, latency to first bar press.
The Neurotoxicology studies shall be incorporated into the system by the end of Year 1.
C. Carcinogenicity Study Design
The system shall be able to collect and report data from an NTP Toxicology and Carcinogenicity study with design specified here: http://ntp.niehs.nih.gov/ntp/Test_Info/FinalNTP_ToxCarSpecsJan2011.pdf, in sections IX (study protocols), VII (pathology), VI (Clinical pathology), XI (report formats), Appendix 5 (Individual Animal Necropsy Reports) and Appendix 6 (Procedures for Sperm Count and Vaginal Cytology Evaluation).
In brief, this requirement is that the system be able to capture data from acute toxicity studies of 2- or 13-week duration, and from carcinogenicity studies of 2-year duration. The system shall be compatible with both feed/water delivery, gavage and inhalation delivery routes. The details of such studies, including endpoints and report structures, are given in the NTP specifications listed above.
The NTP has specific requirements given in the design specifications above for report design and study design which the contractor shall accommodate within the system.
The system shall include the NTP neoplastic glossary, which shall be available to the Contractor during the second year of the contract. An example of the NTP glossary can be found in the NTP path code tables, http://jones.niehs.nih.gov:8080/pct/
The Carcinogenicity study design shall be incorporated into the system by the end of Option 2 (Year 3).
D. Cross-Fostering Study Design
The system shall support data collection and analysis using a cross-fostering study design. In this design all the pups in a litter are moved to the cage of a foster dam, and the pups from the foster dam are moved to the cage of a third dam and so on until no pup in the foster group is housed with its birth mother. This process: (1) moves pups only within a dose group, and if possible (2) only within one study day (preferably PND1). The system shall provide a method to randomly select litters to be moved in this manner.
In a second application of fostering, the system shall support the use of fostering to maintain litter pressure in other studies. The system shall permit one or more pups to be moved to the cage of a foster dam in order to balance the number of pups per litter. The foster pups shall be moved only within a dose group. The system shall record the IDs of the foster pups in such a way that they are not selected for use on the study post weaning.
The Cross-Fostering Study Design shall be incorporated into the system by the end of Option 2 (Year 3).
VII. Options Which May Be Exercised After Completion of Option 1 (Year 2).
1. The system shall support NTP RACB (Reproductive Assessment by Continuous Breeding) reproductive toxicology protocol templates covering four generations (F0 breeder generation plus F1, F2 and F3 generations), and 8000 individually-housed animals per study.
2. Presentation of data from adult male and female animals without an obligatory page beak in any table.
3. The system shall calculate gavage doses for pre-weaning pups based on most recent bodyweight.
4. A report format with only those descriptive statistics the NTP chooses to display (mean, SEM and N) on one row.
These Options may be exercised after the completion of Option 1 (Year 2). At this time, the NTP cannot determine which options shall be exercised or in what year these options may be exercised.
VIII. Reporting Requirements
Quarterly, the Contractor shall deliver a report summarizing the status of the system and progress made in the prior quarter. This report shall be delivered as an electronic Microsoft Word document to the COTR via e-mail.
Annually, the Contractor shall prepare a security report as directed by the COTR.
Annually, the Contractor shall provide a report documenting compliance with Section 508 of the Rehabilitation Act (29 U.S.C. 794d), as amended by the Workforce Investment Act of 1998 (P.L. 105- 220), August 7, 1998. These reports shall be delivered as an electronic Microsoft Word document to the COTR via e-mail.
The Contractor shall provide the system in a secure environment that conforms to the moderate security level described in the Federal Information Security Management Act of 2002 (FISMA), NIST Special Publication 800-53Rev3 and NIST800-63, level 1. The contractor shall certify this capability annually.
Prior to implementing any changes to the system to address capabilities described above the contractor shall deliver a short report which describes the approach which will be taken. Each report will be due six
(6) months prior to final delivery of the system with requested changes. Each report shall be delivered as an electronic Microsoft Word document to the COTR via e-mail.
