Item 1.01 Entry into a Material Definitive Agreement


On September 13, 2022, we and Arena Pharmaceuticals, Inc., (“Arena”) executed a Second Amendment (the “Second Amendment”) to that certain License Agreement dated October 27, 2020, as amended by the First Amendment entered into as of January 28, 2022.


Pursuant to the Second Amendment:

The field of the license of LP659 is expanded to cover, in addition to the indications in the original field licensed to us, all therapeutic, prophylactic, and diagnostic uses in humans for any developmental, degenerative or autoimmune disease, disorder or condition of the central nervous system or peripheral nervous system.
We are providing Arena a right of first negotiation, for a specified period of time following the date of the Second Amendment, to acquire certain development and commercial rights to LP659 products subject to Arena and we mutually agreeing on terms. This right of first negotiation is triggered by our announcing Phase 2 clinical results relating to an LP659 product for an indication that was not in the original field of the license or if we otherwise intend to commence discussions or negotiations to license or partner rights to LP659 in such field.


The foregoing description of the terms of the Second Amendment do not purport to be complete and are qualified in their entirety by reference to the Second Amendment, which we intend to file in redacted form with the Securities and Exchange Commission as an exhibit to our Quarterly Report on Form 10-Q for the quarter ending September 30, 2022.
