Avnst Util

A Python utility package for clinical trial data analysis

Features

• Time Alignment: Tools for aligning and comparing clinical trial event timings
• TEAE Flag Derivation: Utilities for determining Treatment Emergent Adverse Events
• Data Validation: Functions for checking missing or unknown values in clinical data

Installation

pip install avnst_util

Usage

Time Alignment

from avnst_util.time_alignment import align_time

# Align time for an event
start_time, end_time = align_time(
    date="2023-01-01",
    time="14:30",
    event_name="First Dose"
)

TEAE Flag Derivation

from avnst_util.teae_flag_deriver import derive_teae_flag

# Determine if an AE occurred after first dose
teae_flag = derive_teae_flag(
    first_dose_date="2023-01-01",
    first_dose_time="14:30",
    ae_start_date="2023-01-02",
    ae_start_time="09:00",
    opID="SUBJ001"
)

The TEAE flag returns:

• 1: AE definitely occurred after first dose
• 0: AE definitely occurred before first dose
• 2: AE timing overlaps with first dose timing or timing uncertain
• None: Unable to determine timing

Requirements

• Python >= 3.6
• pandas >= 1.0.0
