Please refer to prior comment 13. Your revised disclosure addresses the specific methodology and key assumptions used to determine the fair value of your common stock. Please revise to explain how you determined the enterprise value, which as you state on page 85, is allocated across classes and series of capital stock to determine the estimated fair value of common stock at each valuation date. Please also disclose the nature of the assumptions used in determining the enterprise value. Business Prior Clinical Experience with Epetraborole, page 106 3. We note that you added disclosure stating the observations of clinical resistance were similar to those for rifampicin. It is inappropriate to imply that you are likely to achieve similar results. Please revise your disclosure accordingly. Adjuvant Global Health Agreement, page 115 4. We note your response to prior comment 17. You state on page 115 that given "substantially all NTM development activities, including toxicology studies, clinical trials and manufacturing, overlap with tuberculosis and melioidosis development activities, we believe the risk of repayment related to any future potential investment is low." Please revise this statement in light of the fact that regulatory strategies, product registration, and seeking funding from governmental grants and other granting sources may not overlap with NTM activities.

Please clarify, if true, that you sublicense to Brii Biosciences Limited intellectual property licensed from Anacor Pharmaceuticals.
