Population Description

Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
Enrolled patients were sequentially assigned into one of two dosing groups which consisted of lonafarnib 100mg in group 1 and lonafarnib 200mg in group 2, with placebo controls in each group. Group1 placebo patients received open-label lonafarnib as group 2 participants.

Reporting Groups

	Description
Placebo	placebo control.
Lonafarnib 100 mg	6 participants were randomized to Lonafarnib 100 mg.
Lonafarnib 200 mg	4 participants were randomized to Lonafarnib 200 mg and two "Placebo" participants in Lonafarnib 100 mg arm received open label lonafarnib 200 mg .
