In prior years, the Corporation entered into agreements with Neptune Wellness Solutions Inc.

This license allowed the Corporation to exploit the intellectual property rights in order to conduct clinical trials for its CaPre drug candidate. During the second quarter of fiscal 2021, the Corporation released its Phase 3 clinical programs data and its failure to meet its primary endpoints, and the resulting decision to not file an NDA to obtain FDA approval for CaPre and therefore undertook an analysis to determine the fair value of the intangible asset.
