Lotus Pharmaceuticals, Alvogen, and NRx Pharmaceuticals Inc. announced a global collaboration agreement covering the development and commercialization of NRX-101 for suicidal treatment-resistant bipolar depression (S-TRBD) for global markets. Under the terms of the agreement, relating to NRX-101 for the U.S. market, NRx is entitled to receive an initial payment of $10 million upon achieving both a successful read-out from the ongoing Phase 2b/3 clinical trial in S-TRB and completion of a Type B meeting with the U.S. Food and Drug Administration (FDA). NRx would receive an additional payment of $5 million upon receipt of FDA approval for NRX-101 as well as bonus milestone payments of increasing amounts up to $330 million based on reaching certain net sales targets.

In addition to success-based payments, NRx is eligible to receive a royalty on net sales between 12% and 16% contingent on certain sales thresholds for the U.S. market and other success-based payments for markets outside of the U.S. Lotus will acquire worldwide rights for NRX-101 for treatment of S-TRBD and will be responsible for commercialization of NRX-101 in markets outside of the U.S. through their direct commercial presence in certain Asian markets or through Lotus's export division where the company currently markets an extensive portfolio of products through top-tier partners. Lotus will partner with Alvogen to commercialize NRX-101 for treatment of S-TRBD in the U.S. market through Alvogen's Almatica label. Almatica is the CNS-focused division of Alvogen that currently markets six branded products.

Alvogen and Lotus have committed to fund the next registrational study in suicidal treatment-resistant bipolar depression to support approval of NRX-101 contingent upon successful results of the ongoing Phase 2b/3 clinical trial and completion of a Type B meeting with the FDA. Lotus and Alvogen will have a right of first negotiation for new indications outside of the field of bipolar depression with suicidality for NRX-101 and/or potential new products containing D-cycloserine in combination with an antidepressant /antipsychotic.
