Significant Agreements	15. SIGNIFICANT AGREEMENTS AbbVie Option Agreement On October 31, 2023 (the Option Agreement Effective Date), the Company entered into an exclusive option agreement (the Option Agreement) with AbbVie Inc. (AbbVie), pursuant to which the Company granted AbbVie an exclusive option (the Option) to obtain (a) a co-exclusive license in the United States to facilitate a collaboration with the Company to develop, manufacture and commercialize reproxalap in the United States, (b) an exclusive license to develop, manufacture and commercialize reproxalap outside the United States, (c) a right of first negotiation for compounds that are owned or otherwise controlled by the Company in the field of ophthalmology relating to treating conditions of the ocular surface, and (d) a right to review data for any other compounds that are owned or otherwise controlled by the Company in the fields of ophthalmology and immunology before such data is shared with any other third party (the Collaboration Agreement). AbbVie has paid the Company a non-refundable payment of $1.0 million in consideration of the Option (the Option Payment). On December 21, 2023, pursuant to the Option Agreement, AbbVie extended the period during which it may exercise the Option (the Exercise Period Extension) by paying the Company a non-refundable payment of $5.0 million (the Option Extension Fee). As a result of the Exercise Period Extension, AbbVie may exercise the Option by delivering written notice to the Company at any time during the period following the Option Agreement Effective Date until the earlier of (a) the tenth (10th) business day after the date, if any, that the Company receives approval from the U.S. Food and Drug Administration of the NDA for reproxalap in dry eye disease (the FDA Decision) and (b) the date that is eighteen (18) months after the Option Agreement Effective Date. If the Collaboration Agreement is entered into, the Option Payment and the Option Extension Fee will be credited against the upfront cash payment payable by AbbVie. On November 15, 2024, the Company entered into the Expansion Side Letter (the Expansion Letter) with AbbVie, which amended certain terms of the Option Agreement. The Expansion Letter makes certain changes to the Option Agreement, among other things, providing that the Company will conduct certain launch activities, which costs shall not exceed mid-single-digit millions of dollars without AbbVie’s approval, and which costs will be considered allowable expenses pursuant to the Collaboration Agreement upon the delivery of AbbVie’s written notice of exercising the Option and entry into the Collaboration Agreement, such that 60% of the Company's allowable expenses will be reimbursed by AbbVie in the event of exercise. If AbbVie does not deliver a written notice of exercising the Option and the Company and AbbVie do not execute the Collaboration Agreement, the Company will remain solely responsible for such launch activities costs. AbbVie has also independently initiated pre-commercialization planning activities. In addition, the Exercise Period (as defined in the Option Agreement) was further modified to ten (10) business days following the date, if any, that the Company receives approval from the U.S. Food and Drug Administration of the NDA for reproxalap in dry eye disease (the FDA Decision), provided that AbbVie shall provide the Company notice in case AbbVie determines that it will not exercise the Option. Upon AbbVie’s delivery of the agreement execution notice and the parties entering into the Collaboration Agreement, AbbVie would pay the Company a $100.0 million upfront cash payment, less the Option Payment and the Option Extension Fee. In addition, the Company would be eligible to receive up to approximately $300.0 million in regulatory and commercial milestone payments, inclusive of a $100.0 million milestone payment payable if the FDA Decision is received prior to or after the execution. In the United States, the Company would share profits and losses with AbbVie from the commercialization of reproxalap according to a split of 60% for AbbVie and 40% for the Company. Outside of the United States, the Company would be eligible to receive tiered royalties on net sales of reproxalap. As of May 14, 2025, AbbVie has not exercised the Option. As of December 31, 2023, the Company had recognized no collaboration revenue and had $6.0 million of deferred long-term collaboration revenue related to the Option Agreement and Exercise Period Extension. During the three months ended September 30, 2024, the deferred collaboration revenue was reclassified from a long-term liability to a current liability due to the Option expiring pursuant to the terms of the Option Agreement in less than one year. Although the Option Agreement was not considered to be a vendor-customer relationship, the Company used FASB ASC Topic 606, Revenue from Contracts with Customers, to conclude that the $6.0 million liability would be considered a transaction price (the Transaction Price), and all other amounts due to the Company under the Collaboration Agreement would be excluded from the Transaction Price, since such amounts relate to fees that can only be achieved subsequent to the exercise of the Option. Because the Option Extension Fee and the Option Payment are creditable against the Collaboration Agreement payments due to the Company, the Transaction Price was allocated to a single unit of account, specifically, the option to enter into a future collaboration agreement which is considered a material right. The Company concluded that all other performance obligations were immaterial promises in the context of the Option Agreement and did not represent additional units of account. The Company will begin to recognize revenue if and when the Option is exercised or when the Option expires.
