Non-compartmental analysis (NCA) is a simple and quick method for evaluating the exposure of a drug. It allows you to evaluate things like linearity and in vivo exposure. To illustrate this consider an antibody given in a subcutaneous injection. The actual exposure profile a patient might experience is given in the solid black line in the left panel. But we don’t yet have the ability to sample in a continuous fashion. What we might observer is given by the blue points.
Generally NCA will determine the following directly from the data:
Cmax - Maximum observed concentration
(units=concentration)Tmax - The time where the maximum concentration was
observed (units=time)AUC - The area under the curve (\(units=time \times concentration\))AUMC - The area under the first moment curve (\(units=time^2 \times concentration\))These properties are all based on observational data. So the
Cmax and Tmax will most certainly not be at
the actual maximum concentration but as long as we sample judiciously it
will give us a good approximation. Similarly, the calculated
AUC and AUMC will be different than the actual
values. To calculate the areas you need to dig back into your calculus
text books to the trapezoid method. Basically each sampling interval is
a trapezoid and the area of each is calculated and added up for all of
the n samples:
\[ \begin{eqnarray} AUC &=& \int_0^{t_f} Cdt &\approx \sum_{i=1}^{n-1}{\frac{C_i+C_{i+1}}{2}\times (t_{i+1}-t_{i})} \\ AUMC &=& \int_0^{t_f} t\times Cdt &\approx \sum_{i=1}^{n-1}{\frac{t_iC_i+t_{i+1}C_{i+1}}{2}\times (t_{i+1}-t_{i})} \end{eqnarray} \]
This can be done in Excel pretty easily. Depending on the data and the analysis other properties can be calculated. For example we can calculate the clearance, mean residence time, steady-state volume of distribution and terminal half-life:
Properties like AUC and AUMC can also be be calculated using extrapolation from the last time point to infinity to account for data beyond the observations at hand. The subsequent values of clearance, volumes of distribution, etc can also change with extrapolation.
There is a lot of nuance associated with these calculations, and it
is good to rely on software that focuses on this type of analysis. The
{PKNCA} package has been developed with this in mind. The
ruminate app provides an interface to functionality found in
{PKNCA} and will generate code you can use to get started
with {PKNCA}.
To run NCA you need your data formatted in a specific way. The names of the columns can be defined by the user. Some columns are required, others are optional, and others are only required depending on how the user wants to specify dosing. See below for a general description of the columns followed by more information about how dosing is inferred:
Note that Dose and Concentration need to have the same mass units.
Dosing will be extracted from the datasets, and it can be incorporated in two ways. One is that the dosing information is stored in columns of the dataset. This is the simplest and most straight forward way of storing the dosing information. The other method is that dosing is specified as individual records (rows) in the dataset (if your data is formatted for NONMEM, you can use this).
Beyond the required columns to infer dosing from columns you must also have the following columns defined: Dose, Dosing Cycle or Period, and Nominal Time.
If your dataset is formatted for NONMEM you can extract the dosing from those rows that contain the dosing records. For this case it is expected you will have the following columns in your dataset: Dose (AMT in NONMEM) and Event ID (EVID in NONMEM).
Some notes on dosing information. For each interval where you want to
calculate dose-dependent parameters, you will need to provide
information about dosing in those intervals. In a multiple dose setting
where you have intervals where you do not have enough PK data to run NCA
it, is not necessary to provide dosing information for those intervals.
For example if you have four weekly doses but only have intensive
sampling on weeks 1 and 4 but peak and trough on weeks 2 and 3, you do
not have to provide dosing information for weeks 2 and 3. However there
are certain parameters that {PKNCA} will provide if that
dosing and intermediate sampling information is provided (e.g. time to
steady-state). So if all you are interested in is parameters for
intervals with intensive sampling, then you don’t need to worry about
having dosing information for the other intervals.
If you select an interval for analysis, it is necessary that you have
observations at the beginning and end of that interval. If you do not
have observations at dosing times (e.g. you dose at time zero but your
first observation is at 15 minutes post-dose) and you want to use the
dosing time as the beginning of your interval, you can have an
observation that is BQL or missing (NA) at the dosing time
(zero).
The following shows the different NCA parameters that can be calculated. The PKNCA parameter is value used in PKNCA, and the App Parameter Name is the value shown in the app.

# This is the default shown when the app loads or a new analysis is created
ana_scenario_def: "sd_iv"
# Here are all of the available NCA parameters. Each field is the name of
# the parameter used in PKNCA. See the table in this vignette for the
# available parameters:
#
# https://cran.r-project.org/web/packages/PKNCA/vignettes/v03-selection-of-calculation-intervals.html
#
# Each of parameter has the following
#
# - description: This is a verbose description of the parameter. If set to NULL the
# description from PKNCA will be used. Set it to other text to
# overwrite it. This description will also be used in exports as
# well.
#
# - text: Textual description to show the user. If set to NULL it
# will use the text form PKCNA.
#
# - md: Markdown formatted value of text.
#
# - group: This is how the paramters will be grouped in the UI that
# is generated.
#
# To limit the options the user sees you simply need to comment out the
# parameters you do not want in the App. Alterantively you can use the
# grouping below to have the most common parameters together at the top and
# the remaining in case they are needed.
#
# BILL can you go through the text and md elements below and make any
# changes you think make sense. For example is there a better way to label
# the parameter aucint.inf.obs.dose :).
