We note your response to comment 10 and your revised disclosure stating your belief that "it is unlikely that ALS-1 will experience the resistance developed by the viruses against the existing anti-viral therapy." As you have not yet conducted any clinical studies, it is premature for you imply that ALS-1 will be effective. Please remove this statement. Similarly, please remove the disclosure on page 4 stating your belief that ALS-4 is "less likely to be susceptible to antibiotic resistance." NLS-1: A Derivative pf Epigallocatechin-3-Gallate ("Pro-EGCH") for the treatment of Endometriosis, page 5 4. We note your response to comment 11, which we reissue in part. Please remove your conclusion that studies of EGCG for the treatment of endometriosis have produced "encouraging results." Additionally, please move the discussion of p-values observed to the Business section and expand your disclosure to explain how p-values are used to measure statistical significance and how they relate to the U.S. Food and Drug Administration's evidentiary standards of efficacy. Additionally, please revise your discussion of preclinical studies of NLS-1 stating that it "prevents the progression of fibrosis" and "reduced lesion size significantly better that EGCG and other hormone- based therapy" to remove these conclusions regarding the efficacy of NLS-1. We will not object to a discussion of objective data points in the Business section. Capitalization, page 54 5. We reissue our prior comment 18 since it does not appear that you have revised your capitalization table. Business Lead Projects ALS-1: Small molecule intended for the treatment of viral infections caused by Influenza virus A, page 70 6. We note your response to comment 22. Please expand your disclosure to briefly explain EC50. Additionally, please remove your conclusion that the "animal study results strongly suggest that ALS-1 protected mice against hypervirulent influenza A H5N1 virus in vivo." Please also expand your disclosure on page 72 to briefly explain IC50. Ian Huen Aptorum Group Ltd September 20, 2018 Page 3 Patent License, page 71 7. We note your response to comment 24, which we reissue in part as it does not appear that you have disclosed the aggregate regulatory development and aggregate sales milestones payable under the license agreement. Please revise here and make similar revisions concerning the license agreement related to each of ALS-4 discussed on page 74 and NLS-1 discussed on page 79. Notes to Consolidated Financial Statements (Successor Basis) 14. Summary of Significant Accounting Policies Intangible Assets, page F-37 8. Refer to your response to comment 36. We believe that the aggregate amount of the milestone obligations and the description of the events that would trigger these milestones are significant terms of an agreement that should be disclosed. Please revise your disclosures accordingly.

Refer to Rules 460 and 461 regarding requests for acceleration. Please allow adequate time for us to review any amendment prior to the requested effective date of the registration statement.
