Planimeter’s (Hi)story
First yearsPlanimeter was founded in 1997 by private individuals to provide statistical services in the pharmaceutical industry especially to support clinical trial design and evaluation. The team was formed by 4 people at the beginning and we primarily concentrated on design and analysis of Phase III-IV clinical trials, post-marketing studies and epidemiological surveys.
E-business solutionsWe started our e-business activity in 2005 with preparation of our first Patient Registry. This was followed by further registries and the first e-CRF in 2006. Our e-CRF solution became internally well known and well accepted within a reasonably short time pf period. Probably the main reason of our success is that all our experience on conduction and evaluation of clinical trials were incorporated during design and implementation of the system. Our solution – equipped with a high level help-desk service – currently operates in 8 countries. Besides registries and eCRFs we also developed e-learning, dating and special CRM systems specifically build for health-care system support.
Our today activitiesMeantime Planimeter has became an internally acclaimed, full service CRO of a size of 16 employees and a similar bunch of contractors. Our today activity covers – beyond the original targets – full conduction of clinical trials and reporting - including the medical writing activities.Our strength lays in the strong mathematical background of our staff. We are experienced in both classical (parallel, cross-over, etc.) and modern (Bayesian, Adaptive, etc.) designs. Recently we are focusing on support of translational research and implementation of bioinformatics solution. Main therapeutic areas are: vascular and nervous system disorders, ophthalmology, infections, oncology, renal and urinary disorders, immunology and respiratory disorders. In 2014 Planimeter became an ISO qualified company.

Statistical Programing Statistical Programing primarily means derivation of
Tables, Listings and Graphs (TLGs). This activity is performed with the help of SAS, so Statistical
programing practically means programing in SAS. In wider sense statistical programing covers the majority of CDISC-related tasks because SDTM and ADaM data
tables are also prepared with the help of SAS.
Quality Assurance with ChiliA sophisticated Quality Assurance procedure was
developed and introduced to support the preparation of data models and the process of statistical programing.
QA can be performed with different depth depending on the Sponsor’s requests. The whole procedure is
documented within Chili, a free web-based tool, which was configured specifically for QA-purposes internally.
Data Models (CDISC)CDISC SDTM (Study Data Tabulation Model) is applied to re-structure the raw clinical data into the generally
used domains with the help of variable naming conventions. In this approach the Submission
Metadata Model is followed as far as possible. ADaM (Analysis Data Model) is used to prepare
datasets for direct reporting purposes. The activity is extended with preparation of the Define.xml and
Study Data Reviewer’s Guide.
Management support with ChiliChili is not only suitable for documentation of the QA-
procedure, it also provides environment for delegation of tasks and supervision of both the development and QA-
procedures. With granting access to the Sponsor the whole procedure can be monitored with full transparency.

The Clinical Data Acquisition Standards
Harmonization (CDASH) model standardizes
the way data is collected to facilitate the
generation of SDTM tables. As the primary aim
of following CDASH Guidance is to make
easier and more comfortable to transform
raw study data into SDTM domains, CDASH is
taken into consideration during CRF (and eCRF)
design.
CDASH approach is primarily applied by our Data Management Department, but being a small company
there are not strict boundaries between DM and statisticians or DM and programmers. Consequently majority of our staff including data managers, statistical
programmers and statisticians are familiar with the CDASH standards.
Similarly to the CDASH / CDISC community we are also continuously working on building our CDASH libraries and improvement of already implemented
modules.

SDTM
Preparation of SDTM domains is quite a well defined
procedure, which primarily means the proper application
of the guidance in case of the standard variables and
domains (e.g. sex, age or blood pressure). Due to the
nature of SDTM even the study or therapeutic area
specific variables can easily been transformed into SDTM-
compliant variables with following the naming and
formatting conventions.
As SDTM is a living concept in itself , we pay great
attention to its own development: we intensively follow
the achievements regarding development of Therapeutic
Area Data Standards (TAUGs), Metadata Submission
Guidelines (MSG) or SDTM implementation Guide for
medical devices (SDTMIG-MD).
Our services cover:
• Creation of Data Standards Library including a CRF Library, and CDASH/SDTM/ADaM Libraries
• Set-up Study Specific aggregates mapping visit information into the appropriate visit window structure
• Development of a metadata repository to enable data model compliance checking and define.xml generation
• Comparison against Study Specifications
• Validation against the Data Standards Library
• Generation of pooled analysis based on CDISC data (for ISS or ISE purposes)
• Creation of macros for ADaM dataset creation.
12
SDTM and ADaM data sets are programmed according
to the associated specifications, and validated against a
series of electronic integrity checks to ensure compliance
to the models. Additional QC includes independent
verification of results.
In the Subject-Level Analysis Dataset (ADSL) only one
record is created for all subjects.
In the Basis Data Structures (BDs) one or more records
per subject are generated per analysis parameter, per
analysis time point (conditionally required).
The so called „Other” section of ADaM specifically
contains – among others – the Basic Data Structure for
Time-to-Event Analysis and Data Structure for Adverse
Event Analysis.
ADaM

Define.XMLInformation sharing on the content of SDTM in a more or less human-readable manner led to introduction of Define.xml, which – in short – contains all SDTM data AND metadata in XML-format.
The Standard content of define.XML is :
• Data Metadata (TOC)• Variable Metadata• Variable Value Level Metadata• (Computational Algorithms)• Controlled Terminology/Code Lists• Annotated CRF• Optional: Supplemental Data
Definition Document.
Computational algorithms can also be stored within define.xml framework.
Further advantage of Define.XML: Content can be checked (validated) with define.XML checker programs (e.g. http://www.pharmasug.org/proceedings/2013/AD/PharmaSUG-2013-AD19.pdf).

TLGTables, Listings and Graphs are defined in the Statistical Analysis Plan with the
help of Table Shells. Theoretically table shells defines the outputs with character
precision (in case of Tables and Listings).
Planimeter developed a highly sophisticated SAS-macro set which is able to deliver
the required outputs with very high flexibility. What is the best in our solution that
the macro set can be adjusted through an interface which does not require
programing knowledge. So if no new template is required, the outputs can be put
together simply in a text-editor.
While each study requires some further development of our SAS macro set,
greater and greater part of tables, listings and graphs can be used in off-the-shelf
manner. Today we are generally cover a typical clinical study with pre-defined
outputs in 65-85%.
The advantage of this high coverage is that our TLG generation costs can be
decreased reasonably proportionally with the decrease in work-load.

Quality Assurance ProceduresSteps establishing quality during development phase
• Application of programing conventions
• Commenting and segmenting
• Application of continuously developed macros in TLG-derivation
• Double programming on demand
• TLG-derivation in a three-stage method: development, testing, production
• Complete and transparent documentation of the whole activity (code development and QA)
• Continuous development of standardization according to international standards and guidelines.
Steps establishing quality during QA phase
• Code and output review
• Checking of the applied filtering and sorting in the database s
• Checking of program codes for programming conventions
• Checking log files for errors, notes, messages
• Comparison of the results against the table shells
• Checking of titles, notes, remarks, and spelling.
In case of any discrepancy notification of the programmer and detailed
description of the finding. Response: programmer’s action: fixing the bug or
explanation of the discrepancy. In case of data error notification of project
manager. In case of specification issue notification of the study statistician.

QA in Chili
Chili (https://www.chiliproject.org/) is a free, web-based tool which perfectly fits the demand of managing and documenting of QA-procedures of statistical programing.
Adjustment of the application starts with role definition and set-up of user authorizations.
This is followed by the description of all the potential tasks (the program codes themselves) and finally with the assignment of the tasks to the users (programmers).
When a task is indicated as „ready for validation” the assignments skips to the dedicated QA-person responsible for the specific task.
Not only the work-flow can be commanded within Chili, it also provides area for showing the actual status of a specific program.
17
Management with Chili
Chili is a perfect tool of monitoring
both the program development
procedure and the QA-activities.
Monitoring can be applied at task-level,
when all the activities related with one
specific task are tabulated.
Summary tables of arbitrary sets of
tasks can also be created.
With suitable authorization the
Sponsor can follow the development
and QA-procedure without any
additional effort in real-time.

E-business solutions
Automated Business Data Reporting
There are many data sources (e.g. IMS) which make possible of
preparation of regular reports. Although the same task should be
repeated, sometimes this repetition is not supported within the original software framework. We are able to transform regular data into regular reports with a maximal flexibility.
Patient Support ProgramPatient Support Programs are to
incorporate information collected by usual eCRFs extended with
further study-specific activities of an enrolled subject, like
communication with call-center, patient organisations, dietitians,
running a Diary of rating the different services on regular basis.
E-learning SystemOur e-Learning system has two
roles. First, trains the materials as the
name says. If we consider the SOP-system as a potential material to train/learn, then we arrive to our second task: to provide a job- or
role-dependent delegation of SOPs to be studied to specific 'students'.
Medical Information System
Aim of Medical Information System is to collect, document and manage all potential AE-related information
reaching a pharma headquarter independently of the
communication channel (web, telephone, CRA, trial, etc.). The
system delegates the tasks, logs and reports the activities.
