On May 11, 2020, Galera Therapeutics, Inc. (the “Company”) and Clarus IV Galera Royalty AIV, L.P. (the “Purchaser”) entered into Amendment No. 1 (the “Amendment”) to the Amended and Restated Purchase and Sale Agreement, dated November 14, 2018, by and among the Company, the Purchaser and the other parties thereto (the “Royalty Agreement”), which was filed as Exhibit 10.1 to the Company’s Registration Statement on Form S-1 filed with the Securities and Exchange Commission on October 11, 2019. The Purchaser is affiliated with Blackstone Life Sciences (“Blackstone”), successor in interest to Clarus Ventures.

Under the Royalty Agreement, Blackstone previously agreed to pay the Company, in the aggregate, up to $80.0 million (the “Royalty Purchase Price”), in four tranches of $20.0 million each upon the achievement of specified clinical milestones in the Company’s Phase 3 ROMAN Trial. The Amendment increased the Royalty Purchase Price by $37.5 million to a total of $117.5 million by increasing the fourth tranche from $20.0 million to $37.5 million (the “Fourth Milestone Tranche”) and adding a new $20.0 million tranche upon the achievement of an additional clinical enrollment milestone (the “New Milestone Tranche”).

Pursuant to the Royalty Agreement, as amended by the Amendment, in connection with the payment of each tranche of the Royalty Purchase Price, the Company has agreed to sell, convey, transfer and assign to Blackstone all of its right, title and interest in a high single-digit percentage of (i) worldwide net sales of avasopasem and GC4711 (the “Products”) and (ii) all amounts received by the Company or its affiliates, licensees and sublicensees with respect to Product-related damages (collectively, the “Product Payments”) during the Royalty Period. The Royalty Period means, on a Product-by-Product and country-by-country basis, the period of time commencing on the commercial launch of such Product in such country and ending on the latest to occur of (i) the 12th anniversary of such commercial launch, (ii) the expiration of all valid claims of the Company’s patents covering such Product in such country, and (iii) the expiration of regulatory data protection or market exclusivity or similar regulatory protection afforded by the health authorities in such country, to the extent such protection or exclusivity effectively prevents generic versions of such Product from entering the market in such country.

The amended Royalty Agreement will remain in effect until the date on which the aggregate amount of the Product Payments paid to Blackstone exceeds a fixed single-digit multiple of the actual amount of the Royalty Purchase Price received by the Company, unless earlier terminated pursuant to the mutual written agreement of the Company and Blackstone.

On May 11, 2020, as partial consideration for the Amendment, the Company and the Purchaser entered into a warrant purchase agreement (the “Purchase Agreement”) pursuant to which the Company issued two warrants (the “Warrants”) to the Purchaser to purchase an aggregate of 550,661 shares (the “Warrant Shares”) of the Company’s common stock, par value $0.001 per share (“Common Stock”), at an exercise price equal to $13.62 per share, subject to customary adjustments for stock splits, stock combinations and similar transactions. The first warrant is exercisable for 256,975 of the Warrant Shares and will become exercisable on payment of the Fourth Milestone Tranche and the second warrant is exercisable for 293,686 of the Warrant Shares and will become exercisable on payment of the New Milestone Tranche. The Warrants expire six years after the initial exercise date of each respective warrant.

Under the Purchase Agreement, the Company has provided the Purchaser with customary “piggyback” registration rights, allowing the Purchaser to include the Warrant Shares in certain “shelf” or “resale” registration statements of the Company filed under the Securities Act of 1933, as amended (the “Securities Act”), subject to certain limitations. The Purchase Agreement contains customary indemnification and procedural terms.

The issuance of the Warrants is exempt from registration pursuant to Section 4(a)(2) of the Securities Act and Regulation D promulgated thereunder, as a transaction by an issuer not involving a public offering. The Purchaser has acquired the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends have been affixed to the securities issued in this transaction.

The information contained in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02.
