Amendment No. 2 to Draft Registration Statement on Form F-1 Submitted November 24, 2020 CIK No.: 0001818838 Dear Mr. Luo: We have reviewed your amended draft registration statement and have the following comments. In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. Please respond to this letter by providing the requested information and either submitting an amended draft registration statement or publicly filing your registration statement on EDGAR. If you do not believe our comments apply to your facts and circumstances or do not believe an amendment is appropriate, please tell us why in your response. After reviewing the information you provide in response to these comments and your amended draft registration statement or filed registration statement, we may have additional comments. Unless we note otherwise, our references to prior comments are to comments in our November 10, 2020 letter. Draft Registration Statement on Form F-1 Submitted on November 24, 2020 Prospectus Summary Overview Our Pipeline, page 5 1. We note your response to our prior comment 2 and your revised pipeline table that shows your trial 1001 for ADG126 has already commenced Phase Ia. However, your disclosures only indicate that you have received authorization to begin the trial from the Australian authorities, and from the FDA, subject to submission of a revised agreed-upon Peter (Peizhi) Luo FirstName LastNamePeter (Peizhi) Luo Adagene Inc. Comapany9, December NameAdagene 2020 Inc. December Page 2 9, 2020 Page 2 FirstName LastName protocol, but not that the trial has commenced. Please reconcile your disclosures. In addition, please explain why it is appropriate to show Phase Ia and Phase Ib as two separate columns when your discussions for ADG126 and ADG116 only refer to "Phase I". Please also explain why it is appropriate to retain the US 1001 trial for ADG116 in the pipeline table when you do not currently plan to enroll patients in this clinical trial. ADG126: Novel anti-CTLA-4 SAFEbody candidate, page 7 2. We note your use of the phrase "potency" to describe certain preclinical observations. For example only, we note your revised disclosures here and elsewhere in your prospectus where you state that "ADG126 in addition to its potency for Treg depletion in TME suggests its potential for tolerable and potent monotherapies" and that "preclinical results support the further clinical evaluation of ADG116 both as tolerable and potent monotherapies and combination therapies for a wide range of tumor types." As ADG126 is only in the preclinical stage, and as safety and efficacy determinations are solely within the FDA's authority and they continue to be evaluated throughout all phases of clinical trials, please remove these and any similar references. Where you deem appropriate, you may present objective data resulting from your trials without including your conclusions related to safety or efficacy.
