This presentation discusses the transformation of pharmacokinetic (PK) data from its original source to the standard SDTM submission format. PK data comes from various clinical trial sources and needs to populate the SDTM PC and PP domains with linked records in RELREC. Challenges include mapping variables, relating records across domains, and deriving parameters in PP from concentrations in PC. Intermediate ADaM datasets like ADPC are often needed to perform analyses and populate PP. Care is required to represent timing criteria, flags, and other analysis-related attributes correctly between the domains.
Implementation of CDISC ADAM in The Pharmacokinetics DepartmentSGS
SGS Life Science Services as a leading CRO, is one of the pioneers in the implementation of CDISC standards. Given the positive experiences in the SGS Data Management and Biostatistics Departments (implementation of SDTM and ADaM respectively), the Pharmacokinetics (PK) Department recently decided to adopt the CDISC standards as well.
In an SDTM database, pharmacokinetic data is stored as one record per subject, per time point (PC domain) or per pharmacokinetic parameter (PP domain). For the PK analysis, the generation of Tables, Listings and Figures, and the statistical analysis on PK parameters, ‘analysis ready’ datasets are created.
A complex ADaM dataset - three different ways to create oneKevin Lee
The paper is intended for Clinical Trial SAS® programmers who create and validate a complex ADaM dataset. Some ADaM datasets require the use of complex algorithms. These algorithms could require several steps of data manipulation and more than one SDTM datasets. It can be very challenging to create a complex ADaM dataset in accordance with ADaM data structures and standards. Furthermore, it can be equally as challenging to validate those ADaM datasets. The paper will introduce three different ways to create a complex ADaM dataset. The first way is to create ADaM from SDTM directly without any intermediate permanent datasets. The second way is to create ADaM through the intermediate permanent datasets like SDTM+ or ADaM+ from SDTM. The third way is to create the final ADaM through the intermediate ADaM from SDTM. The paper will discuss the benefits and limitations of each method and also show some examples.

CDISC's CDASH and SDTM: Why You Need Both!Kit Howard
CDISC's clinical data standards are widely used for clinical research, but many people wonder why there seem to be two standards for collected data: the Clinical Data Acquisition Standards Harmonization (CDASH) standard and the Study Data Tabulation Model (SDTM) standard. This poster steps through four significant reasons that reflect the differences in philosophy, intermediate goals and broad-scale uses. Examples illustrate each reason and how they affect your studies.

The use of Adaptive designs is becoming quite popular and well-perceived by the regulatory agencies such as the FDA in the US. “Adaptation” can occur in different fashion and potentially make studies more efficient (e.g. shorter duration, fewer patients) more likely to demonstrate an effect of the drug if one exists, or more informative (see “Adaptive Design Clinical Trials for Drugs and Biologics” FDA guidance).
The aim of this presentation is to illustrate a case where an adaptive design was used in a Phase III oncology pivotal study having Overall Survival as a primary end-point. The particular adaptation implemented was an un-blinded SSR that applied a promising zone approach.
The main focus will be how the adaptive design impacted the SDTM modelling, the design of some ADaM datasets (e.g. those containing the time-to-event endpoints and therefore using ADTTE ADaM model) and later on how some mapping and analysis decisions were described in both the study and analysis reviewer guide.

Meaningful (meta)data at scale: removing barriers to precision medicine researchNolan Nichols
Randomized controlled trials (RCTs) are the gold standard for evaluating therapeutics in patient populations. The data collected during RCTs include a wealth of clinical measures, biomarkers, and tissue samples – the analysis of which can lead to the approval of new medicines that improve the lives of patients. The secondary use of these data can also fuel the discovery of novel targets and biomarkers that support precision medicine, but a lack of metadata standards creates substantial barriers to reuse.
For this talk, I will discuss the challenges that arise when aggregating diverse types of data from a large number of RCTs and present a case study in how to apply (meta)data standards for the scalable curation and integration of these data into an analysis ready form.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

CRISPR-Cas9, a revolutionary gene-editing tool, holds immense potential to reshape medicine, agriculture, and our understanding of life. But like any powerful tool, it comes with ethical considerations.
Unveiling CRISPR: This naturally occurring bacterial defense system (crRNA & Cas9 protein) fights viruses. Scientists repurposed it for precise gene editing (correction, deletion, insertion) by targeting specific DNA sequences.
The Promise: CRISPR offers exciting possibilities:
Gene Therapy: Correcting genetic diseases like cystic fibrosis.
Agriculture: Engineering crops resistant to pests and harsh environments.
Research: Studying gene function to unlock new knowledge.
The Peril: Ethical concerns demand attention:
Off-target Effects: Unintended DNA edits can have unforeseen consequences.
Eugenics: Misusing CRISPR for designer babies raises social and ethical questions.
Equity: High costs could limit access to this potentially life-saving technology.
The Path Forward: Responsible development is crucial:
International Collaboration: Clear guidelines are needed for research and human trials.
Public Education: Open discussions ensure informed decisions about CRISPR.
Prioritize Safety and Ethics: Safety and ethical principles must be paramount.
CRISPR offers a powerful tool for a better future, but responsible development and addressing ethical concerns are essential. By prioritizing safety, fostering open dialogue, and ensuring equitable access, we can harness CRISPR's power for the benefit of all. (2998 characters)

PCTEST –. Represents analyte (Usually). Long, chemical names possible.
Inconsistent spellings frequent
• For urine samples, can contain different info, e.g. specific gravity,
total volume collected.
PCTESTCD – Will need to develop shortened versions of Analyte. Can be
difficult for long names that are similar to one another.
PCCAT – If PCTEST is an Analyte, then PCCAT = “ANALYTE”. If PCTEST is
urine descriptive variable, then PCCAT = “SPECIMEN PROPERTY”.
Note: PCCAT has very different meaning than PPCAT.
PCGRPID – Use in conjunction with RELREC to relate PP to PC.

20. ADaM- ADPC and ADPP
Points to Ponder
Similar to the creation of ADPC, the PP domain is merged with ADSL and derived
variables are added to create ADPP. In the BDS structure, following variables derivation
will need to pay attention to:
AVISIT/ AVISITN : AVISIT and its numeric counterpart AVISITN are derived from the
variables VISIT and VISITNUM from the PC domain.
All PK concentrations (in ADPC) or all PK parameters (in ADPP) that refer to
the same exposure will have the same AVISIT(N) value.
ATPT/ATPTN :The planned analysis time points Only for pre-dose values they differ
from the PCTPT and PCTPTNUM The value of PCTPTNUM, which is in general
negative for predose samples, is put to zero in ATPTN.
PCTPTNUM having the planned time points in minutes, it can be converted
to e.g. hours in ATPTN. These variables are not present in ADPP.
ANLzzFL: Analysis record flags (ANLzzFL) can be used to select a set of records for
one or more analyses. The “zz” can carry value from 0-99.
As multiple analysis flags can be assigned, a new variable, analogue to
ANLzzFL, is needed to define the different analysis groups: ANLzzFD
(Analysis Record Flag zz Description).
20
21. ADaM- ADPC and ADPP
Points to Ponder
● In ADPC, the main analysis groups are:
● ‘PK analysis’, ‘Descriptive statistical analysis’ and ‘Steady state analysis’.
In ADPP, the main analysis groups are:
‘Inferential statistical analysis’ and ‘Descriptive statistical analysis’. Subjects, time
points or PK parameters can be included or excluded from analyses based upon
criteria or as specified in the protocol/SAP.
● AVAL/AVALC. In most cases, it is equal to PCSTRESN, the numeric result in standard
unit. The character counterpart is reported in AVALC
● For example, values that are below the limit of quantification can be put to zero.
● CRITy, CRITyFL, CRITyFN Analysis criteria are evaluated in CRITy. The “y” is used to
categorize the different criteria and will be replaced with a single digit: 0-9.
● Two important criteria in PK analysis are,
● time deviations and
● quantifiable predose values.
If a sample is taken more than 10% too soon, or too late relative to the scheduled time
point, the value can be excluded from the descriptive statistical analysis
