sales milestones required for every licensed product commercialized by Quoin Inc. are $10 million upon achievement of $100 million in sales being achieved in the annual period; $25 million upon achievement of $250 million in sales and $50 million upon the achievement of $400 million in sales in an annual period. On January 27, 2021, Quoin Inc. and Skinvisible entered into an amendment which modified the clinical milestone payment requirements such that $750,000 would be payable to Skinvisible upon achievement of specified clinical milestones, and $21.75 million upon regulatory approval in the U.S. and EU respectively. No development milestones, sales milestones or royalty payments were due through in 2019, 2020 or 2021.
The agreement has a termination clause that is triggered if no product has commenced clinical testing 12 months after the date of the agreement or the latest subsequent amendment. On April 19, 2021, Quoin Inc. and Skinvisible entered into another amendment which established the development deadline as December 31, 2022. Should the Company not commence clinical testing as defined by the development deadline, the license agreement will terminate immediately except in certain circumstances as specified in the agreement.
The license fee was originally due in two equal installments of $500,000 payable no later than December 31, 2019 and June 30, 2020, which were not paid. The agreement was subsequently amended for payment due on July 31, 2020. On July 31, 2020, the agreement was amended to further extend the payment until September 30, 2020. On September 30, 2020, the agreement was again amended, requiring payment of the license fee only when outside financing is received, as defined in the agreement. On June 21, 2021, the parties entered into an additional amendment which modified the payment terms and required a payment of $107,500 on June 26, 2021, a payment of $250,000 within 10 days of the Primary Financing, and the remaining $250,000 upon the earlier of approval of an Investigatory New Drug application by the FDA or December 31, 2021. This amendment also eliminated the $750,000 clinical milestone payments described above and reduced the milestone payment upon regulatory approval of the product containing the Skinvisible technology in either the U.S. or E.U., whichever happens first to a total of $5,000,000.
At December 31, 2021 and December 31, 2020, the license acquisition liability due was $250,000 and $875,000 respectively. The remaining license acquisition liability has not been paid in accordance with the terms but has not impaired the Company’s rights to the technology as the Company is in the process of renegotiating this payment with Skinvisible.
The major research and development vendors utilized by the Company include the following:
Quoin Inc. entered into three consulting agreements with Axella Research LLC (“Axella”) to provide regulatory and pre- clinical/clinical services with respect to QRX003 and QRX004. The combined fees of the three agreements are approximately $270,000, payable as milestones under the three agreements are met. Quoin Inc. has also engaged Axella for additional services pursuant to separate work orders. Further, Quoin Inc. has two options to pay the milestones due 1) one half in equity (at a pre-negotiated valuation) and one-half in cash or 2) entirely in cash, in which case a discount of approximately 20% would be applicable. We recognized research and development expenses for services provided and milestones met of approximately $247,000, $50,000 and $25,000 for the years ended December 31, 2021, 2020 and 2019, respectively, and have accrued expenses of $193,537, $105,052 and $24,940 at December 31, 2021, 2020 and 2019, respectively.
In November 2020, Quoin Inc. entered into a Master Service Agreement for an initial term of three years with Therapeutics Inc. for managing preclinical and clinical development for new products in the field of dermatology. The agreement required the execution of individual work orders. Quoin Inc. may terminate any work order for any reason with 90 days written notice subject to costs incurred through termination and a defined termination fee, unless there is a material breach by Therapeutics Inc. The first work order was entered into in late 2020 for a clinical study at an expected estimated cost of approximately $3.5 million and expected timing through the first quarter of 2023. For the year ended December 31, 2021, we incurred approximately $340,000 of research and development costs related to this agreement.
In November 2021, we entered into a commitment with Queensland University of Technology for research related services associated with Netherton Syndrome of approximately $250,000 for an expected period of eighteen months, of which an initial $25,000 expense was incurred in 2021.
