Everyone asks: what exactly do you learn in 90 days?

Here is the complete week-by-week breakdown.

Weeks 1–3 — Base SAS Foundation:
Data step and PROC step. SAS macros. PROC SQL joins. Arrays for batch processing. Merging and appending. These are the tools that power everything else.

Weeks 4–6 — CDISC SDTM Programming:
Create DM, EX, AE, LB, VS, DS domains from real CRF data. Learn SDTM IG 3.3 standards. Annotate CRFs. Run and fix Pinnacle 21 validation errors.

Weeks 7–9 — ADaM Dataset Creation:
Build ADSL with population flags, TRTSDT, SAFFL, ITTFL. Create ADAE with TRTEMFL. Build ADLB, ADVS, ADTTE from SDTM. Real derivation specs throughout.

Weeks 10–11 — TLF + Define-XML:
Generate tables, listings, and figures per a SAP. Create Define.xml 2.1 from scratch with value level metadata. Full Pinnacle 21 cross-validation.

Week 12 — Projects + Interview Ready:

🚀 Advanced Clinical SAS | Day 26

Controlled Terminology in CDISC Submissions

Controlled terminology provides standardized values for clinical trial data and improves consistency across datasets, studies, and submissions.

Common terminology sources include:

✔ MedDRA – Medical conditions, adverse events and indications
✔ WHODrug – Drug and substance terminology
✔ CDISC/NCI Controlled Terminology – Standardized clinical data terms
✔ SNOMED CT – Clinical terminology
✔ LOINC – Laboratory and clinical observation terminology
✔ ISO 8601 – Date and time representation

Using the appropriate terminology helps reduce inconsistent coding and improves data quality.

Best Practice

Always verify the terminology version used by the study and ensure that the applicable version is correctly documented in the study metadata.

Consistent terminology supports standardized analysis, data exchange, regulatory review, and cross-study comparison.

Clinical SAS — by the numbers.

₹35 LPA+
The maximum salary for a Senior or Lead Clinical SAS programmer with 8+ years of experience at a global pharma company. This is not a rumour — I see it in real job postings.

90 Days
The time it takes to go from zero SAS knowledge to being interview-ready, if you practice every single day. Not 6 months. Not 2 years. 90 days.

20+
The typical number of SDTM domains in a single Phase III clinical trial submission. That is how complex — and how important — this role is.

2016
The year the FDA made Define.xml mandatory for all CDISC-compliant drug submissions. That mandate created a permanent demand for Clinical SAS programmers.

1000+
The number of students trained at Sudarshan SAS Class since we started. Placed at ICON, IQVIA, Indegene, TCS, Cognizant, Soterius, Phaster and more.

16+
Years of active pharma industry experience of our trainer. Not retired. Not teaching from memory. Doing real clinical trial work right now.

Any of these numbers surprise you?

Next batch coming soon.

🚀 Advanced Clinical SAS | Day 25

LB Domain in SDTM – Key Variables You Must Know

The LB domain represents laboratory test results and is one of the most important SDTM findings domains used in clinical trials.

Important variables include:

✔ LBTESTCD – Laboratory Test Short Name
✔ LBTEST – Laboratory Test Name
✔ LBORRES – Original Result
✔ LBORRESU – Original Units
✔ LBSTRESC – Standardized Result Character
✔ LBSTRESN – Standardized Result Numeric
✔ LBSTRESU – Standard Units
✔ LBSTNRLO – Lower Reference Range
✔ LBSTNRHI – Upper Reference Range
✔ LBDTC – Collection Date/Time
✔ LBSEQ – Sequence Number

These variables provide standardized representation of laboratory observations and form an important source for analysis datasets such as ADLB.

Correct mapping and standardization of laboratory data are essential for reliable safety and efficacy analyses.

People often ask me: what does a Clinical SAS programmer actually do every day?

Here is an honest answer from someone who does it.

9 AM — I open the SDTM programming specifications document. I review the CRF annotation for the domains assigned to me that sprint.

10 AM — I write the SAS data step to create the AE domain. Map AETERM, AEDECOD, AEBODSYS, AESEV, AESER from raw CRF variables. Every variable has a source and a derivation rule.

12 PM — I run Pinnacle 21 validation on the AE dataset. Three errors today. ERR-006 (DOMAIN mismatch) and WARN-021 (date format). Fix and rerun.

2 PM — QC session. I compare my output with the independent programmer's output. Any discrepancy must be documented and resolved.

4 PM — The biostatistician added a new variable to the LB domain. I update the Define.xml to include it with correct metadata.

5 PM — A biostatistician asks why two subjects have TRTEMFL = 'Y' despite starting AEs before treatment. I investigate. EXOCCUR was missing for those subjects. TRTSDT was wrong. I fix it and document the issue.

That's one day.

And that's exactly what I teach at Sudarshan SAS Class. Not theory — the actual workflow.

Next batch coming soon.

🚀 Advanced Clinical SAS | Day 24

What Is the Difference Between AE and CE Domains in SDTM?

Both AE and CE capture clinical events, but their purpose and collection context are different.

AE – Adverse Events

AE is used to represent adverse events and other untoward medical occurrences collected during a clinical study.

Examples may include:

✔ Headache
✔ Nausea
✔ Vomiting
✔ Injection-site reaction

AE data commonly supports safety analysis.

CE – Clinical Events

CE is used for protocol-defined clinical events that are not appropriately represented as adverse events.

These events may be important for evaluating study objectives, disease progression, or other predefined clinical outcomes.

Key Principle

AE → broader safety-event concept

CE → protocol-defined clinical-event concept

The correct domain should be determined from the study protocol, CRF, collection context, and applicable SDTM implementation guidance.

Accurate domain selection helps preserve the meaning of the collected clinical data.

Most Clinical SAS freshers can name AE and LB domains.

Few can map every domain to its correct category and explain why.

Here is the complete SDTM universe — and how interviewers expect you to talk about it.

4 categories. Every domain fits into one.

Special Purpose — the foundation:
DM (Demographics) is created first. Always.
Every other domain's USUBJID links back to DM.
TA, TE, TS, TV, TI are trial design domains.

Interventions — what was given to the patient:
EX is what makes a subject part of the safety population.
CM captures everything else the patient was taking.

Events — what happened to the patient:
AE is the most scrutinised domain in any submission.
DS captures whether the patient completed or withdrew.
MH documents what was there before the trial even started.

Findings — what was measured:
LB, VS, QS, EG — all the objective data collected during visits.
These feed directly into ADaM datasets like ADLB and ADVS.

The key insight: DM anchors everything. EX drives TRTSDT in ADSL. AE feeds ADAE. LB feeds ADLB.

That's not just knowledge — that's understanding.

5 myths about Clinical SAS that I hear from freshers every single week.

And why every single one of them is wrong.

Myth 1: "You need a programming background."
Wrong. I have trained engineers, pharmacists, statisticians, and complete beginners. The ones who practice daily — all of them learn.

Myth 2: "Only B.Pharm graduates qualify."
Wrong. M.Sc Statistics, Biotech, Life Sciences, even working professionals in unrelated fields — all are in our batches right now.

Myth 3: "SAS is dying because of Python and R."
Wrong. The FDA mandates CDISC-standard submissions. Those submissions require SAS. Until that regulation changes — Clinical SAS programmers have guaranteed demand.

Myth 4: "AESER and AESEV mean the same thing."
Wrong — and this answer costs candidates their job offer. Serious is a regulatory classification. Severity is a clinical rating. They are independent of each other.

Myth 5: "90 days is not enough time."
Wrong. Saleem. Madhavi. Sowmya. All placed in 90 days or less. From zero SAS knowledge.

Which myth did you believe before reading this?

🚀 Advanced Clinical SAS | Day 23

How Do You Derive ADT and ADTSDTC in ADaM?

ADT and ADTSDTC are important date/time variables used in analysis datasets.

ADT represents the analysis date associated with an analysis record.

ADTSDTC represents the analysis start date/time when the analysis requires date and time information.

For example, an ADLB record may use the laboratory collection date/time from SDTM LB as the source for its analysis date/time, depending on the analysis requirements.

Key Points

✔ Follow the analysis specifications.
✔ Preserve the appropriate date/time precision.
✔ Use ISO 8601 representation where applicable.
✔ Do not create artificial time information without a defined rule.
✔ Maintain consistency between source and analysis datasets.

ADT can also be used for analysis-day calculations, visit assignment, and other time-based derivations.

The exact derivation should always follow the study-specific SAP and programming specifications.
