Study Details

Study Description

Brief Summary

The study is being conducted to explore the safety and effectiveness of a new chemical entity, BGC20-1531, in subjects with a history of migraine. In this study subjects will treat a total of three migraine attacks with two different doses of BGC20-1531 and placebo, with at least one week wash out period between doses.

Condition or Disease	Intervention/Treatment	Phase
Migraine	Drug: BGC20-1531 Drug: Lactose	Phase 2

Detailed Description

Migraine headache is estimated to affect 10-20% of the world population and is listed by the World Health Organisation in the top 20 causes of disabling conditions, and in the top four neurological disabling conditions. The most common therapies for acute migraine are non-steroidal anti-inflammatory drugs (NSAIDs) and triptans. However, many migraine sufferers do not experience sufficient relief from these treatments or cannot tolerate their gastrointestinal, cardiovascular and other side-effects.

Prostaglandin PGE2-induced sensory nerve sensitisation, neuropeptide release and cerebral vascular dilatation is thought to underlie migraine pain, particularly via activation of the EP4 receptor subtype. BGC20-1531 is an orally available EP4 receptor antagonist which inhibits prostaglandin-induced vasodilation of cranial blood vessels via a selective blockade of EP4 receptors reducing inflammation and migraine pain. As EP4 receptors are discretely localised, the overall safety profile of EP4 receptor antagonists may be improved compared to triptans and NSAIDs.

Outcome Measures

Primary Outcome Measures

To evaluate the effect of BGC20-1531 on headache response, defined as a decrease of headache from severe or moderate to mild or none at 2 hours post-dose without the use of rescue medication. [2 hours]

Secondary Outcome Measures

To evaluate the effect of BGC20-1531 on pain-freedom up to 48 hours post-dose without the use of rescue medication. [Up to 48 hours]
To evaluate the effect of BGC20-1531 on headache response up to 48 hours post-dose (without the use of rescue medication). [Up to 48 hours]
To evaluate the effect of BGC20-1531 on sustained headache relief and pain-freedom over a 24-hour and 48-hour period post-dose. [Up to 48 hours]
To evaluate the safety of BGC20-1531. [Duration of the study]
