Minoryx and Neuraxpharm form alliance to get rights to new therapy for rare CNS disease


Minoryx Therapeutics and Neuraxpharm Group have announced a strategic alliance for the European rights to a new therapy for rare central nervous system (CNS) disease.

The companies have entered into a license agreement for leriglitazone, currently under European Medicines Agency (EMA) review for the orphan indication X-linked Adrenoleukodystrophy (X-ALD).

Under the agreement, Minoryx grants Neuraxpharm exclusive European rights to lead candidate leriglitazone, which is a brain penetrant and selective PPAR gamma agonist. Neuraxpharm obtains exclusive rights to commercialize leriglitazone in Europe and will join with Minoryx to continue the further development of leriglitazone. Minoryx retains full rights to leriglitazone in the US and the rest of world, excluding already partnered China.

Minoryx retains full rights

As part of the agreement, Neuraxpharm has agreed to pay Minoryx a significant double-digit upfront payment in addition to milestone payments and development funding totalling up to €258 million ($266 million) in the aggregate. Also, Minoryx will further receive material tiered double-digit royalties.

Minoryx and Neuraxpharm will collaborate on concluding the ongoing European regulatory process to obtain approval for leriglitazone for the treatment of adult male patients with X-ALD. Leriglitazone will be the first approved treatment for this population if it is approved by the EMA. Minoryx and Neuraxpharm are further committed to jointly continue the development of leriglitazone for additional X-ALD patient populations and other orphan indications.

Tapping into the business segment of orphan drugs to treat rare diseases via this license agreement is a new approach for Neuraxpharm. In this strategically relevant step, the company builds on its extensive CNS expertise stemming from 35 years in the field of CNS disorders. Neuraxpharm will create a center of excellence dedicated to leriglitazone. With this, Neuraxpharm plans to accelerate diagnosis and allow for early treatments through better population screening and shorter referral ways. Another important part of the work will consist of closely collaborating with patient advocacy groups and associations.

New approach for Neuraxpharm

Jörg-Thomas Dierks, CEO of Neuraxpharm said: “This agreement is not only an important strategic step for Neuraxpharm, it will also be to the benefit of patients who may not be too numerous but whose medical needs are as urgent as they can get. Helping them and at the same time entering a highly attractive business area with a great partner like Minoryx is something I am very proud of.”

“Minoryx remains fully committed to ensure that leriglitazone reaches X-ALD patients as quickly as possible. With the Neuraxpharm partnership Minoryx has secured a strong partner that will enable an optimal launch of leriglitazone throughout Europe. Minoryx selected Neuraxpharm specifically for its expertise in the European central nervous system marketplace and its substantial experience and capabilities in successfully commercializing CNS drugs in Europe,” said Marc Martinell, CEO, Minoryx.

“Minoryx will continue the development and regulatory preparations for the US and is currently in discussions with the FDA to define the next steps for the US approval path.”
