Overview

Multiple studies are done in animals to ensure safety of an Active Pharmaceutical Ingredient (API) prior to initiation of clinical trials. Pharmacologist or toxicologist may want to compare among the studies. So app generate a plot that shows all doses with calculated exposure margin, any user provided notes, and findings with degree of severity. Plot can be customized with other input button like sliders, drag and drop and checkbox. App also generate multiple summary table for all of the studies. Summary table also highly customizable and can be downloaded in different format.

Program Tab

On the landing page (Program tab) there is a button on bottom of the left sidebar called “Need Help?”. When user click on the button it will show how to use the app and will provide self guided tour for all the button in this page. User can crate new program by selecting New program in ‘Select Program’ input. This page have multiple other tab for figure and tables.

Edit Clinical Tab

There is a button on top of the left column called “Need Help?”. When user click on the button will provide self guided tour for all the button in this page.
Clinical Dosing chechbox have options to provide more information about dose. When user select a dose, there are more options appeared. By default, dose are in mg/day. But user can choose mg/kg. User need to make sure that unit match for provided clinical and nonclinical dose.

Edit Nonclinical Tab

There is a button on top of the left column called “Show Help Button”. When user click on this button, it will show two other button
1. Need Help? start here
2. Manual Entry
These button will provide self guided tour to this page and give information what all input button does and how to enter data here. There are two workflow for data entry.
1. Automated data entry
2. Manual data entry
If SQLite database connected to database then app can get all the study information from the study and fill out appropriate input. But If App run without database connection, User can fill out all the information manually here about study. In both case user still need to provide findings manually in the right column.

Database Connection

User can enter nonclinical data manually or nonclinical data can be filled out from database. To extract from database, user need to create a SQLite database from Standard for Exchange of Nonclinical Data (SEND). Instruction for how to create SEND database can be found here https://github.com/phuse-org/sendigR. When user choose to connect to database, user need one csv file that map studies to a corresponding program number. An example file can be found here link.

number	id
155580	CJ16050
155580	CJUGSEND00
155580	Study ID
155581	Nimort-01
155581	PC201708
155582	GLP003
155582	PDS2014
155582	CV01

for above example, study ID GLP003, PDS2014 and CV01 in id column, all belong to program number 155582 (last 3 rows). Make sure first column contain program number and second column contain study ID number.

Plot

When user create an program and add study information, app will create plot and plot will be shown on program tab. Plot can be think of as two subplot. On the left plot, one big rectangular represents one study and small rectangular box represents dose. If the color of small rectangular box is green, it represent No Observed Adverse Effect Level (NOAEL) dose. Other doses are colored black. Mouse hovering on dose box will show exposure margin. User can select to show dose and exposure margin same time from checkbox. On the right plot, dose box is color coded with degree of severity of finding. Mouse hovering on box will show finding. The whole plot can be customized by changing the different input located at the top of the plot.

Tables

App generate multiple summary table located right side of the figure tab. Clinical relevance table is group by findings. User can look into which finding is common across studies. Table also show reversibility, dose and exposure margin information. The key finding table show all the findings that are found at greater than NOAEL dose for a study. Table also include NOAEL, Cmax, AUC and safety margin column. The safety margin table show all the studies that have NOAEL dose. It filter out all the other study that does not have NOAEL dose. Table include NOAEL, HED (Human Equivalent Dose) Cmax, AUC, safety margin at proposed clinical dose. There is a notes table that show all the notes if user provided note while adding the study in nonclinical section. All the table can be downloaded as csv, Excel and microsoft word file. User also can download all the plot as image (jpeg file).
