On December 13, 2021 (the “Execution Date”), Arbutus Biopharma Corporation (the “Company”) entered into an Exclusive License Agreement (the “License Agreement”) with Qilu Pharmaceutical Co., Ltd. (“Qilu”), pursuant to which the Company granted Qilu an exclusive (except as to the Company’s retained rights as set forth below), sublicensable, royalty-bearing license, under certain intellectual property owned by the Company, to develop, manufacture and commercialize the Company’s product candidate, AB-729 (the “Licensed Compound”), including pharmaceutical products that include the Licensed Compound (each, a “Licensed Product” and collectively, “Licensed Products”), for the treatment or prevention of hepatitis B (the “Field”) in China, Hong Kong, Macau and Taiwan (the “Territory”). With respect to the Licensed Compound, the Company retains non-exclusive rights to develop and manufacture the Licensed Compound in the Territory, and exclusive rights to develop, manufacture and commercialize the Licensed Compound and Licensed Products outside the Field in the Territory and in the Field and outside the Field in the rest of the world.
In partial consideration for the rights granted by the Company, Qilu agreed to pay to the Company (i) a one-time upfront cash payment of $40 million payable within 30 business days of the Execution Date, and (ii) milestone payments totaling up to $245 million, net of withholding taxes, upon the achievement of certain technology transfer, development, regulatory and commercialization milestones.
Qilu also agreed to pay the Company double digit royalties into the low twenties percent based upon annual net sales of Licensed Products in the Territory. The royalties are payable on a Licensed Product-by-Licensed Product and region-by-region basis commencing on the first commercial sale of a Licensed Product in a region and continuing until the later to occur of (i) the expiration of the last valid patent claim covering or claiming the composition of matter, method of treatment, or method of manufacture of such Licensed Product in such region, (ii) the expiration of regulatory or data exclusivity for such Licensed Product in such region, and (iii) the tenth anniversary of the first commercial sale of such Licensed Product in such region (collectively, the “Royalty Term”). The royalty rate is subject to reduction under certain circumstances, including when there is no valid claim of a licensed patent that covers a Licensed Product in a particular region or following the existence of a defined level of generic competition to a Licensed Product in a particular region.
Qilu is responsible for all costs related to developing, obtaining regulatory approval for and commercializing the Licensed Products in the Field in the Territory. Qilu is required to use commercially reasonable efforts to develop, seek regulatory approval for, and commercialize at least one Licensed Product in the Field in the Territory. A joint development committee will be established between the Company and Qilu to coordinate and review the development, manufacturing and commercialization plans with respect to the Licensed Products in the Territory. The Company and Qilu also agreed to negotiate in good faith the terms and conditions of a supply agreement and related quality agreement pursuant to which the Company will manufacture or have manufactured and supply Qilu with all quantities of the Licensed Product necessary for Qilu to develop and commercialize the Licensed Product in the Field in the Territory until the Company has completed manufacturing technology transfer to Qilu and approval of a Qilu, or its designated contract manufacturing organization, manufactured product by National Medical Products Administration in China for the Licensed Product.
The License Agreement will expire on a Licensed Product-by-Licensed Product and region-by-region basis on the date of the expiration of the Royalty Term in such region. Upon expiration of the License Agreement, Qilu will have a fully paid-up, freely transferable, perpetual license to use the patent rights and know-how licensed from the Company to research, develop, have developed, manufacture, have manufactured, use, sell, offer for sale, import, export and otherwise commercialize the applicable Licensed Product in the Field in the Territory. Either party may terminate the License Agreement for the other party’s material breach following a cure period or upon certain insolvency events. Qilu may terminate the License Agreement at its sole discretion and without any penalty or liability for any reason or no reason upon twelve months prior written notice to the Company.
The License Agreement includes customary representations and warranties, covenants and indemnification obligations for a transaction of this nature.
The foregoing description of the terms of the License Agreement is not complete and is qualified in its entirety by reference to the full text of the License Agreement, which the Company intends to file as an exhibit to the Company’s Annual Report on Form 10-K for the annual period ended December 31, 2021.
