Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Sum of Total Pain Relief (TOTPAR) over 0-6 hours post-dose	Pain relief will be evaluated considering the Sum of Total Pain Relief (TOTPAR) over 0-6 hours post-dose. Pain relief will be evaluate using a Categorical Pain Relief Rating Scale (0 = No relief, 1 = a little relief, 2 = some relief, 3 = a lot of relief, 4 = complete relief).	6 hours post-dose
Secondary	Sum of Total Pain Relief (TOTPAR) over 0-4 and 0-8 hours post-dose	Pain relief will be evaluated considering the Sum of Total Pain Relief (TOTPAR) over 0-4 and 0-8 hours post-dose. Pain relief will be evaluate using a Categorical Pain Relief Rating Scale (0 = No relief, 1 = a little relief, 2 = some relief, 3 = a lot of relief, 4 = complete relief).	4 and 8 hours post-dose
Secondary	Sum of Pain Intensity Difference (SPID) over 4, 6 and 8 hours post-dose.	Sum of Pain Intensity Difference (SPID) over 4, 6 and 8 hours post-dose. The pain intensity will be assessed using a Categorical 4-point scale (0 = no pain, 1 = mild pain, 2 = moderate pain, 3 = severe pain).	4, 6 and 8 hours post-dose
Secondary	Use of rescue medication	Proportion of participants who used rescue medication in the first 24 hours after the first drug intake, amount of rescue medication used in the first 24 hours after the first drug intake, and time elapsed between the last drug intake and the first administration of rescue medication.	24 hours post-dose
Secondary	Number of additional drug intake	Number of additional drug intake during the 24 hours after the first drug intake	24 hours post-dose
Secondary	Patients' Global Impression of Change (PGIC)	Patients' Global Impression of Change (PGIC) will be assessed after 8 hours post-dose or immediately before the intake of rescue medication.	8 hours post-dose
Secondary	Incidence of Adverse Events Associated with DEH113 in the Treatment of Primary Dysmenorrhea	The safety will be evaluated considering the incidence of adverse events (AEs) reported during the study period.	7 days post dose
