aactr

aactR

R package to connect and interact with clinical trials data via the AACT

Installation

Install the package from GitHub using devtools package

library(devtools)
install_github("ineelhere/aactr")

If you don’t have the devtools package already please install it with install.packages("devtools")

Check if the package got installed by importing it

library(aactr)

AACT Setup

• Sign up at https://aact.ctti-clinicaltrials.org/users/sign_up
• You will need the Username and Password you created.

Using the package features

👉 To connect to the AACT database, use the connect_aact() function:

library(aactr)
conn <- aact_connect(username, password) 

username and password should be the same as your AACT account.

👉 To quickly check if your AACT db connection is actually fetching data:

library(aactr)
check_connection(conn)

Note, we just used the conn connection created earlier.

You should expect an output similar to -

                        study_type
1 Observational [Patient Registry]
2                   Interventional
3                  Expanded Access
4                             <NA>
5                    Observational

👉 To refer to AACT database schema and details

library(aactr)
get_schema()

👉 To run custom queries for fetching data from the AACT database

library(aactr)

get_query(
  conn, 
  query = "
    SELECT 
      nct_id, 
      source, 
      enrollment, 
      overall_status
    FROM 
      studies
    LIMIT 
      5;
  "
)

You may define the query string outside the function call, store it in a variable and just pass it to the get_query() function.

Expected output:

       nct_id                         source enrollment     overall_status
1 NCT05762861            University of Minho        200 Not yet recruiting
2 NCT02950012                  BIO-CAT, Inc.        100          Completed
3 NCT05251298   University Hospital Muenster        370         Recruiting
4 NCT01376921 Merck KGaA, Darmstadt, Germany        300          Completed
5 NCT05237219             University of Pecs          0          Withdrawn
