Creating ADIS

Introduction

This article describes how to create an ADIS ADaM domain. The parameters derived reflects common vaccine immunogenicity endpoints.

Examples are currently presented and tested using ADSL (ADaM) and IS and SUPPIS (SDTM) inputs.

Note: All examples assume CDISC SDTM and/or ADaM format as input unless otherwise specified.

Programming Workflow

Read in Data

In this first step you may read all the input data you need in order to proceed with ADIS development. In this template, SDTM.IS, SDTM.SUPPIS and ADAM.ADSL has been used.

library(admiral)
library(dplyr)
library(lubridate)
library(admiraldev)
library(admiralvaccine)
library(pharmaversesdtm)
library(metatools)
library(pharmaversesdtm)

# Load source datasets
data("is_vaccine")
data("suppis_vaccine")
data("admiralvaccine_adsl")

# Convert blanks into NA
is <- convert_blanks_to_na(is_vaccine)
suppis <- convert_blanks_to_na(suppis_vaccine)
adsl <- convert_blanks_to_na(admiralvaccine_adsl)

Combine IS with SUPPIS

Combine IS with its supplemental domain SUPPIS.

is_suppis <- metatools::combine_supp(is, suppis)

Derive Timing Variables

Derive AVISIT, AVISITN, ATPT, ATPTN and ATPTREF variables. Please, update visit records according to your Study Design/Protocol. For the visit values, please refers to your ADAM SPECIFICATIONS.

adis <- is_suppis %>%
  mutate(
    AVISITN = as.numeric(VISITNUM),
    AVISIT = case_when(
      VISITNUM == 10 ~ "Visit 1",
      VISITNUM == 20 ~ "Visit 2",
      VISITNUM == 30 ~ "Visit 3",
      VISITNUM == 40 ~ "Visit 4",
      is.na(VISITNUM) ~ NA_character_
    ),
    ATPTN = as.numeric(VISITNUM / 10),
    ATPT = case_when(
      VISITNUM == 10 ~ "Visit 1 (Day 1)",
      VISITNUM == 20 ~ "Visit 2 (Day 31)",
      VISITNUM == 30 ~ "Visit 3 (Day 61)",
      VISITNUM == 40 ~ "Visit 4 (Day 121)",
      is.na(VISITNUM) ~ NA_character_
    ),
    ATPTREF = case_when(
      VISITNUM %in% c(10, 20) ~ "FIRST TREATMENT",
      VISITNUM %in% c(30, 40) ~ "SECOND TREATMENT",
      is.na(VISITNUM) ~ NA_character_

Derive AVAL, AVALU and DTYPE Variables

This is the core of ADIS template.

For ORIGINAL (and relative log10 values) the following rule has been followed for AVAL derivation:

For 4fold (and relative log10 values) the rule is pretty the same, except when the LAB result (ISSTRESN) is lower than the Lower Limit Of Quantitation. In that case put ISSTRESN instead of ISSTRESN/2.

With log10 transformations, simply follow the before rules and apply log10 function.

Please, update this algorithm according to your Protocol/SAP.

AVALU is set equal to IS.ISSTRESU.

Later you can find SERCAT1/N and DTYPE derivations.

DTYPE is filled only for those records who exceed or are below the ISULOQ and ISSLOQ, respectively. If ISULOQ is not present, DTYPE is filled only when lab result is below Lower Limit of Quantitation.

Derive CRITx Variables

Derive Criteria Evaluation Analysis Flags.

The function selects a subset of rows from the input dataset and apply a criterion to them. If this criterion is met then CRIT1FL (or the name you specified in the first argument) is equal to Y; N otherwise.

The function returns a relative numeric CRIT1FN variable (1 or 0 if the criterion is met, respectively) and a label CRIT1 variable (with the text specified in label_var argument).
