ADaM DAY 2 : ADLB   Abstract: ADLB stands for Laboratory Test Result Analysis dataset is an important safety dataset, it captured all the Lab test results for each treatment cycle per patient. We can the Lab dataset to visualize the change of lab test results based on the time change for each patient (Spider Plot) or the overall lab-test distribution…


ADaM day 1: ADaM.ADAE stands for Adverse Event  Analysis dataset : This dataset is crucial for safety analysis in a new drug development progress as well as in post-market safety updates. it contains the information of ADSL, AE, SUPPAE. The dataset ADAE captured adverse event’s name, length, start and end date, relation to the drugs, actions to resolve the adverse…


ADaM Day 1 In clinical trials, ADSL(Subject-Level Analysis Dataset) is the foundation of all ADaM analysis dataset, it is one record per subjects; it captures subjects’ population flag 🚩, treatment-related info, vital sign info♂, baseline disease info, and other info respect to different study designs.

Basic Oncology 101

  Today I will share some Basic Oncology Knowledge I found in my old notebook:  RECIST 1.1: Complete Response (CR): Disappearance of all non-nodal target lesion Partial Response (PR) : At least 30% decrease in the sum of diameters of target lesions compared with the baseline sum diameters.

ISS & ISE Info

  Background Story:       Once my friend said her team members cried during a meeting, i thought it was funny then. However, when I started to work in their team, I wanted to cry, too. What was the challenge? It was ISS/ ISE related work!  


SDTM day 6: Vital Sign Introduction: the Vital Sign domain captures all the measurements of body’s most basic functions, such as height, weight, blood pressure, heart rate… VS is a critical dataset in Drug Safety Analysis.


SDTM Day 5: SDTM.EX   Introduction: Exposure dataset contains the details of subjects’ study treatment information, it is one of the key safety datasets, and it is critical to efficacy analysis. The EX domain is intended for “protocol-specified study treatments” including placebo dosing. The EX dataset would present a complete and accurate of subjects’ exposure in one record per constant dosing to the reviewers.


SDTM Day 4 : SDTM.AE Adverse Event is an event that results in unintended harm to the patient by an act of commission or omission rather than by the underlying disease or condition of the patient, thus AE Dataset is very important to Safety analysis for drug testing. It captures Adverse Event dates and various Adverse Event information for each patient. The…


SDTM Day 3 : LB, Laboratory Dataset   Last Time we introduced SDTM.LB for laboratory Test Results in Finding General Observation Class and Showed an example of how to merge with SV(Subject Visit) to get Epoch. SDTM.LB is one of the most crucial datasets for Drug Safety Analysis, it could be challenging due to the vast amount of records. This…
