Cystic Fibrosis Development Award

On April 20, 2015, the Company entered into an award agreement with the CFFT, a non-profit drug discovery and development affiliate of the Cystic Fibrosis Foundation, pursuant to which it received a development award (the “Award”) for up to $5 million in funding. The funding from the Award is supporting a first-in-patient Phase 2 clinical trial of the Company’s Resunab drug in adults with cystic fibrosis (CF). Upon the execution of the Award agreement, the Company received a payment of $1,250,000 in May 2015 from the CFFT (See Notes 3 and 8). In the fourth quarter of 2015, the Company received a second payment of $1,250,000 from the CFFT upon the achievement of a milestone for dosing the first patient. In 2015, the Company recorded these amounts received from the CFFT totaling $2,500,000 as deferred revenue. The Company is amortizing these amounts on a straight-line basis over the expected duration of the performance period of the development program under the award, which is expected to conclude in the first quarter of 2017. In August 2016, the Company received a $1,000,000 payment from the CFFT for achieving a milestone in July 2016 related to dosing the median clinical trial patient as per the terms of the Award. The remaining $1,500,000 under the Award is expected to be paid to the Company incrementally by the end of the fourth quarter of 2016 or in the first quarter of 2017 upon the achievement of certain milestones related to the progress of the Phase 2 CF clinical trial, as set forth in the Award agreement.

Pursuant to the terms of the Award agreement, the Company is obligated to make royalty payments to the CFFT contingent upon commercialization of Resunab in the Field of Use (as defined in the Award agreement) including a royalty payment equal to five times the amount the Company receives under the Award agreement, up to $25 million, payable in three equal annual installments following the first commercial sale of Resunab, the first of which is due within 90 days following the first commercial sale of Resunab. The Company is also obligated to make a royalty payment to CFFT equal to the amount the Company receives under the Award agreement, up to $5 million, due in the first calendar year in which the aggregate cumulative net sales of Resunab in the Field of Use exceed $500 million. Lastly, the Company is obligated to make royalty payment(s) to the CFFT of up to approximately $15 million if the Company transfers, sells or licenses Resunab in the Field of Use other than for certain clinical or development purposes, or if the Company enters into a change of control transaction, with such payment(s) to be credited against the royalty payments due upon commercialization. The Field of Use is defined in the Award as the treatment in humans of CF, asbestosis, bronchiectasis, byssinosis, chronic bronchitis/COPD hypersensitivity pneumonitis, pneumoconiosis, primary ciliary dyskinesis, sarcoidosis and silicosis. Either the CFFT or the Company may terminate the agreement for cause, which includes the Company’s material failure to achieve certain commercialization and development milestones. The Company’s payment obligations survive the termination of the Award agreement.
