Biomarkers
are indicators of a biological response related to disease
progression or remission. Carefully selected biomarkers can be
useful in the selection of a lead compound, determining the
mechanism of action of a compound, be used as a surrogate
endpoint for demonstrating efficacy, or for identifying
intermediate endpoints of success to decrease follow-up time
with a specific treatment. Many biomarkers are in an ELISA
format and can be either in the form of a kit or custom assay.
The validation of these immunoassays according to GLP, final
sample analysis with a panel of biomarkers, and the monitoring
of assay performance requires the processing of various forms
of data and multiple data points per patient or specimen.
ALIS-IC 2000™
software incorporates features such as encrypted electronic
signatures, complete audit trail and password protected task
based access that allows us to meet several GLP compliance
requirements for automated systems and satisfies the needs of
these demanding studies.
The use of ALIS-IC 2000 allows bi-directional data
transfer.
A sample sequence run list is generated and uploaded to
StatLIA™ for
instrument control and the results of assay are transferred
back to ALIS-IC 2000 using an instrument upload module.
The assay results are then processed based on
parameters defined by study, method and protocol.
Finally the data are reported using ALIS-IC 2000's
Seagate Crystal Report Writer and MS-WORD 2000/VBA based
application that can be customized to meet study specific
requirements.
In this presentation, we will describe our approach to
automating a high throughput immunoassay data processing and
reporting using
ALIS-IC 2000.

Contract research organizations
(CRO) operating under FDA-GLP are faced with two opposing
challenges; maintaining high productivity and compliance with
the evolving regulatory electronic record-keeping
requirements. Over the past ten years, LCMS laboratory
managers have steadily improved laboratory productivity via
automation of data acquisition and reporting. The drive
towards laboratory automation and compliance with electronic
record keeping is converging to define a common platform
necessary to achieve the paperless CRO. FDA has
recently presented guidance regarding electronic record
keeping requirements issued in Part 11; Electronic Records;
Electronic Signatures (21 CFR 11)1,2 . The
purpose of Part 11 was to address the electronic record
keeping and signature requirements in "Paperless Record
Systems". Some of the key requirements for regulated
systems include: - Validation - Ability to Generate Accurate
and Complete Copies - Archival Protection of Records - Audit
Trails - System Controls - Personnel Training and
Qualifications ALTA has incorporated the electronic record
keeping and signature procedures into ALIS98™, an LCMS
report writer3-5 that are required of regulated
systems. The purpose of this presentation is to describe our
approach to implementing these new features including an
electronic audit trail, encrypted electronic signatures and
enhanced system controls towards satisfying the FDA
requirements. Much of the design considerations were based on
information presented at the 1998 SQA Workshop (Alexandria,
VA) as well as presentations available at the FDA web site
(http://www.fda.gov). We invite discussions with others who
supply FDA with equivalent data as to how they accomplish the
same goal.

Method validation studies
require processing of method performance experimental data and
generation of custom analytical reports. Although
there is some similarity between validation plans, (contract
research organization) CRO's typically see considerable
variation in design due to compound and sponsor driven
requirements. In addition to differences in experimental
design, method validation report formats are often dictated by
sponsor (versus CRO) standard operating procedures (SOP).
These factors complicate any efforts to streamline report
generation via software automation.
One approach towards providing
a flexible reporting tools to study managers has been the
utilization of MS Office97 automation. The advantage of
this approach is that MS Word97 is used throughout many if not
all pharmaceutical companies and FDA. Tracking and
processing of method validation trial results can be handled
by a MS-Access97 database and user interface constructed with
MS-Visual Basic (Visual Basic or Visual Basic for
Applications). Report data can be queried and written
into a pre-designed and preformatted MS Word97 document
templates using Access97 -SQL via MS DAO (Data Access Object)
library version 3.5. Besides enabling rapid application
development, report writers also benefit from using a
validated significant figure subroutines to ensure consistent
numerical formatting. This poster describes the method
validation report writing module developed for ALIS-98, a
LC-MS/MS data management and reporting system. |

Purpose:
To evaluate the effects of regression model selection on
statistical measures traditionally used to assess quantitative
data set acceptability including bias of standards, r2
and QC percent recovery.
Method: LCMS/MS data
from a single dose safety and pharmacokinetic study was
evaluated using the LCMS Report Writer, ALIS-DMPRA 4.0.
Designs details of ALIS including a description of
functionalities has been presented elsewhere . The data which
consisted of five analytical runs and 16 subjects were
generated on a PE-Sciex API III + operating in turbo-ionspray
tandem mass spectrometry mode. Standard concentrations ranged
over three orders of magnitude (0.005 - 5.0 ng/mL).
Calibration sets were processed using weighted, non-weighted,
linear, quadratic regression and log-log quadratic regression.
All regression calculations were performed using the ALIS
Calibration Optimizer module and verified by Jandel's
TableCurve 4.0 for Windows (Figure 1).
The coefficient of determination (r2) and the fit
standard error were used to assess good-ness of fit for each
calibration curve-regression model combination. In addition,
the bias of the lowest calibration standards and QC samples
were determined to examine the effect of curve fit on data
acceptability. Subject data were processed within the ALIS
Pharmacokinetic/SGI Data Analysis module to generate t 1/2 for
all subjects and three PK models: zero-order, first-order and
compartment independent. To compare the results across
regression types, the relative percent difference was
calculated using the t 1/2 from the weighted linear regression
1/x2 as a reference point.
Results: These results
suggest curve fit selection should be based on a goodness of
fit measure such as Standard Error (Root MSE). In this study,
regression model selection had a significant effect on the
bias of standards and QC samples.
Conclusion: Future work
should examine procedures for outlier selection and rejection.

The use of high speed automated
analytical procedures such as LC/MS/MS in support of FDA/EPA
data submissions has markedly increased over the past five
years. Instrument through-put can easily exceed several
hundred result records per analytical run creating the need
for software capable of performing real-time post-acquisition
data processing and report generation. LCMS based
pharmacokinetic reports and field dissipation reports are
typically method or protocol specific requiring a high degree
of flexibility in the design of the report writer software.
ALIS, a windows based LCMS report writer, allows the creation
of study specific sample log-in screens, electronic
benchsheets, and report forms customizable through an
extensive set of user utilities. The ALIS report writer
currently supports automated data transfer from two instrument
platforms: the Finnigan XSQ 700/7000 and the Sciex API 3/300.
ALIS employs two template
builders to facilitate the collection and processing of data
based on study specific requirements. Method templates are
created that dictate sample preparation and instrument
operation parameters. Post-acquisition quantitation options
are also assigned to the method template including the type of
calibration curve fitting, sample response types and any
result correction factors that will be applied to the data.
The use of method templates greatly reduces laboratory errors
due to method deviations and promotes the generation of a
uniform study database.
To accommodate as many study
types as possible, the ALIS user interface allows the
alteration of the underlying sample descriptor database
structure by the user. Allowing the user to create study
specific sample log-in templates has enabled a high degree of
flexibility in the back-end grouping and sorting of analytical
results. Post processed data can be stored in MS Access,
Oracle or any RDBMS capable of supporting ODBC. In the case of
MS Office based ALIS, results data sets can be queried from
Access using SQL, stored query definitions or through thin the
above third party report writers. |
