Note 6—License Agreements

During the nine months ended February 29, 2016, the Company executed a license agreement with a third-party licensor covering the licensor’s “system know-how” technology with respect to the Company’s use of proprietary cell lines to manufacture new PRO 140 material. The license agreement required a payment, which was accrued as of May 31, 2015, of £600,000 (approximately US$915,000) by December 15, 2015. In connection with this license agreement, the Company became the primary obligor of an additional payment of £600,000 (approximately US$930,000) due on June 30, 2016. This amount was subject to reduction depending on the amount, if any, recovered by the licensor in certain litigation involving Progenics Pharmaceuticals, Inc. (“Progenics”), the company that sold PRO 140 to CytoDyn. During the nine months ended February 29, 2016, the Company recorded an additional expense of £600,000 (approximately US$930,000), as probability of any recovery from third-party litigation was not reasonably estimable. Recently, the licensor resolved its litigation with Progenics. No financial payment was made by either party to the other in connection with the settlement of the litigation. As such, CytoDyn remains fully liable for the previously accrued license fee due on June 30, 2016. Future annual license fees will be £300,000 (approximately US$450,000).

Under the Asset Purchase Agreement, dated July 25, 2012, between the Company and Progenics Pharmaceuticals, Inc. (“Progenics”) (the “Asset Purchase Agreement”), the Company acquired from Progenics its rights to the HIV viral-entry inhibitor drug candidate PRO 140 (“PRO 140”), a humanized anti-CCR5 monoclonal antibody, as well as certain other related assets, including the existing inventory of bulk PRO 140 drug product, intellectual property, certain related licenses and sublicenses, and U.S. Food and Drug administration (“FDA”) regulatory filings. On October 16, 2012, the Company paid to Progenics $3,500,000 in cash to close the transaction. The Company is also required to pay Progenics the following milestone payments and royalties: (i) $1,500,000 at the time of the first dosing in a U.S. Phase 3 trial or non-US equivalent, which was paid during the three months ended February 29, 2016; (ii) $5,000,000 at the time of the first US new drug application approval by the FDA or other non-U.S. approval for the sale of PRO 140; and (iii) royalty payments of up to 5% on net sales during the period beginning on the date of the first commercial sale of PRO 140 until the later of (a) the expiration of the last to expire patent included in the acquired assets, and (b) 10 years, in each case determined on a country-by country basis. To the extent that such milestone payments and royalties are not timely made, under the terms of the Asset Purchase Agreement, Progenics has certain repurchase rights relating to the assets sold to the Company thereunder.

Payments to the third-party licenser and to Progenics are in addition to payments due under a Development and License Agreement, dated April 30, 1999 (the “PDL License”), between Protein Design Labs (now AbbVie Inc.) (“PDL”) and Progenics, which was assigned to the Company in the Asset Purchase Agreement, pursuant to which the Company has an exclusive worldwide license to develop, make, have made, import, use, sell, offer to sell or have sold products that incorporate the humanized form of the PRO 140 antibody developed by PDL under the agreement and must pay additional milestone payments and royalties as follows: (i) $1,000,000 upon initiation of a Phase 3 clinical trial, which was paid during the three months ended February 29, 2016; (ii) $500,000 upon filing a Biologic License Application with the FDA or non-U.S. equivalent regulatory body; (iii) $500,000 upon FDA approval or approval by another non-U.S. equivalent regulatory body; and (iv) royalties of up to 7.5% of net sales for the longer of 10 years and the date of expiration of the last to expire licensed patent. Additionally, the PDL License provides for an annual maintenance fee of $150,000 until royalties paid exceed that amount. To the extent that such milestone payments and royalties are not timely made, under the terms of the PDL License, AbbeVie Inc. has certain termination rights relating to the Company’s license of PRO 140 thereunder.

Pursuant to the foregoing Asset Purchase Agreement and PDL License, the Company accrued an expense of $2,500,000 as of May 31, 2015 in connection with the anticipated milestone payments related to the first patient dosing in a Phase 3 clinical trial, all of which was paid during the three months ended February 29, 2016, as described above.
