Visualisation to show Completion Dates for Trials

Hi

I would be very grateful if a solution/ suggestion to the question below can be provided

I have a list of drugs which have different trials with associated completion dates.  E.g  Drug A has 100 trials which have different completion dates.  These trials are  classified or filtered according to

1. grades 3,2,1,
2. status which has 3 options (Active, Trial Withdrawn and Suspended) only Trials with Active status will be used in the visual 
3. completion Date which has values, of  Not available, Unknown or Blank or actual date but only those with actual dates will be used.

Task:

The task is to display the list of drugs on the Y-axis and the different trials with completion dates on the x-axis in a visual. We would like to include a color scheme whereby all trials with a Completion date will be grey in color, Trials which have the answer Yes to the question unique trial? will be green .

Desired result:

 I had tried using the gant chart visual but it would not display the individual trial and completion date. However we achieved the screenshot below in Tableau using  a text table. But we would prefer to create the Power BI equivalent to the picture below.

 Data table is below:

How can this be achieve?
