Trial Outcomes & Findings for A Study to Evaluate the Long-Term Safety of M207 in the Acute Treatment of Migraine (NCT NCT03282227)

NCT ID: NCT03282227

Last Updated: 2020-08-19

Results Overview

Number and % of subjects in safety population with any treatment-emergent adverse event(s) during the study. TEAE is defined as any new adverse event (AE) that started after first patch application. This was an open-label study with no control group. No statistical analyses were performed. Application site skin reactions including erythema, swelling, haemorrhage, bruise, pain, and pruritus were collected systematically via subject e-diary and/or investigator skin assessment at study visits. All other AEs were spontaneously reported by subject or observed upon examination.

PRIMARY outcome

Timeframe: 0 to 12 months

Population: Safety Population included 335 subjects (98.0%) who received any amount of study drug (applied at least 1 patch).

Number and % of subjects in safety population with any treatment-emergent adverse event(s) during the study. TEAE is defined as any new adverse event (AE) that started after first patch application. This was an open-label study with no control group. No statistical analyses were performed. Application site skin reactions including erythema, swelling, haemorrhage, bruise, pain, and pruritus were collected systematically via subject e-diary and/or investigator skin assessment at study visits. All other AEs were spontaneously reported by subject or observed upon examination.

SECONDARY outcome

Timeframe: 2 hours for each Migraine, up to 12 months for each subject

Population: Modified intent-to-treat (mITT) Population included all subjects who received any amount of study drug to treat a qualifying migraine, and who had efficacy data.

Percentage of migraine attacks for which pain freedom defined as a pain level of 'None' (Grade 0 on pain severity scale where 0: None, 1: Mild, 2: Moderate, 3: Severe, and lower values represent a better outcome) was achieved at 2 hours post-dose without the use of rescue medication. This was an open-label study with no control group. No statistical analyses were performed.

Population: Modified intent-to-treat (mITT) Population included all subjects who received any amount of study drug to treat a qualifying migraine, and who had efficacy data.

Percentage of migraine attacks for which pain relief defined as an improvement of pain severity (1) to mild (Grade 1) or none (Grade 0) from moderate (Grade 2) or severe (Grade 3) at baseline, or (2) an improvement of pain severity to none (Grade 0) from mild (Grade 1) at baseline, without rescue medication was achieved. Pain severity scale has grades: 0: None, 1: Mild, 2: Moderate, 3: Severe, where lower values represent a better outcome. This was an open-label study with no control group.
